OBJECTIVE: We aimed to explore the lived experiences of informal caregivers for pregnant women seeking scheduled antenatal care during the early stage of China's COVID-19 lockdown and potential measures to address the challenges. DESIGN: This is a phenomenological qualitative study. SETTING: The study was carried out in a leading teaching hospital in Southwest China. PARTICIPANTS: We recruited 15 informal caregivers for healthy pregnant women on routine antenatal visits about six months after China launched the city-wide lockdown and other control measures for COVID-19, including 10 males and 5 females with diverse demographic backgrounds. MEASURES AND FINDINGS: The research team developed a demographic form and an interview outline with key questions, conducted semi-structured interviews with the informal caregivers, and analyzed the data using the Colazzie's method. Five themes of lived experiences were revealed, i.e., increased caregiving burdens, disruption of routines in family life, lack of accurate information and knowledge, active role adjustment, and positive attitudes and coping in a difficult time. Some caregivers reacted positively to the lockdown experience and saw it as an opportunity to rethink their lives and improve family relations. KEY CONCLUSIONS: The informal caregivers experienced increased physical and psychological burdens. Strategies such as adoption of a less frequent prenatal visit schedule, use of tele-medicine technologies, and provision of accurate information and knowledge may help to ease the increased informal caregiving burdens. Psychological counseling, community services and disaster response policies specially targeting pregnant women and their informal caregivers may also be valuable resources. IMPLICATIONS FOR PRACTICE: Attention should be drawn to the group of informal caregivers for pregnant women during a COVID-19 lockdown, including professional assistance delivered by nursing and other related professionals. Measures are called for to minimize exposure opportunities such as adoption of a new prenatal care schedule and tele-medicine technologies. Patient education with reliable information should be provided, preferably by nursing staff and physicians. Social support efforts including professional mental counseling may added and work with other resources such as community services and policy makers.

A cluster of serious pneumonia cases caused by an unknown pathogen was reported in Wuhan, capital city of Hubei province, China in December 2019 (Zhou et al., 2020) . The new virus was soon confirmed to be transmissible between humans (Chan et al., 2020) , which was later officially named the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the condition it causes the coronavirus disease 2019 (COVID-19) (WHO, 2019). The Chinese government was quickly alerted and responded with a range of local and nationwide control measures. In tackling further spread of the virus, transportation in and out of Wuhan, the epicenter was suspended from 23 January 2020, after which the entire Hubei province was isolated the following day. On the same day of Wuhan's lockdown, the Chinese state authority raised its national public health response level to the maximum level of emergency, i.e., Level 1 in China's 4-level Emergency System. Other control measures were introduced nationwide, including screening and isolation of suspected and confirmed cases, suspension of public transit, closure of all schools and entertainment venues, ban on public gatherings, prohibition of travel in and out of cities, and dissemination of information on mass media (Tian et al., 2020) . Personal actions were required according to health authority recommendations, including frequent airing and disinfection of home environment, wearing a proper facial mask whenever going outdoors or entering a public space, and handwashing with soup water (China CDC, 2019). Certain essential public services remained operational, including hospitals providing prenatal care. The hospitals also introduced prevention and control mechanisms according to the national guidelines, such as taking temperature of every person entering the premises, designating separate space and passages for suspected cases, required wearing of facial masks at all times, isolating and referral of suspected and confirmed patients to a local designated hospital treating COVID-19 patients (China CDC, 2019).

As one of the most important life events in Chinese culture, childbearing has been traditionally stressed and pregnant women are well cared for, both professionally and informally. Prenatal visits are a common practice among Chinese childbearing women (National Health Commission of the People's Republic of China, 2019), who will typically register her case with one of the local obstetrics hospitals and visit the hospital at least ten times for routine checkups before laboring given that her gestation is not clinically complicated according to the guidelines of Chinese Medical Association (Chinese Medical Association, 2018) . Informal prenatal care is often provided by the pregnant woman's family members, primarily one or more of her parents or parents-in-law. The husbands share some of the care tasks, who usually continue to work. Remunerated external help, such as a family relative, friend, and/or a hired nanny or sitter, may also be used, often in more affluent families. The informal caregiving includes preparing special diet, assistance with daily living activities, and providing company and support for pregnant women. The carers may often accompany the pregnant women on prenatal visits.

After the Chinese cities were locked down and other stringent control measures devised for the COVID-19 pandemic, the circumstances in which informal prenatal care was delivered were drastically changed. As a result, the behaviors and real-world experiences of the informal caregivers were changed significantly. The external help was no longer available due to the lockdown and transport ban. The tasks incurred by caregiving were different and increased. Many of the carers experienced greater burdens from caregiving. After searching the main databases including PubMed  , the Cochrane Library, Embase  and Ovid  , we were unable to find any literature focusing on the group of informal caregivers for pregnant women, reporting their experiences during the COVID-19 lockdown, or suggesting strategies to address possible challenges.

On the current study we aimed to explore the lived experiences of informal caregivers for pregnant women during the early stage of COVID-19 lockdown in China and some promising strategies to alleviate their caregiving burdens based on existing research results. Our findings may contribute to the understanding of the status quo of informal prenatal caregiving during the COVID-19 pandemic and shed light on useful measures to address similar situations in the continual COVID-19 lockdowns and future disaster events.

This is a phenomenological qualitative study to explore lived experiences of informal caregivers for pregnant women during the COVID-19 lockdown in China. Colaizz's method was employed for data analysis (Edward & Welch, 2011) .

The study was ethically approved by the Academic Ethics Committee, Second Affiliated Hospital, Sichuan University (approval number YXKY194). After explaining the study to candidate participants in details before each interview, informed consents were signed with both the pregnant woman and her informal caregiver after they indicated full understanding.

The current study took place in a tertiary teaching hospital for woman and child health affiliated to a university in Chengdu, Sichuan province of Southwest China. The city is located over 1,000 km away from Wuhan, the COVID-19 epicenter. National response measures were implemented in the city, such as citywide lockdown, suspension of transit, identification and quarantine of infected and suspected patients in the local hospitals designated to treat COVID-19, frequent personal hygiene and disinfection, and required use of personal protective equipment. The hospital was not a designated facility for admitting COVID-19 patients. An internal screening protocol was in place to identify and isolate any possibly infected individual, including such measures as automated body temperature measurement of all persons entering the facility with a thermal imaging system at the entrance, subsequent screening procedures outside each department, separate waiting areas and a fever clinic for febrile patients, and a specialist consultation and referral protocol for suspected cases.

We used purposive sampling to enroll participants. The primary investigator (first author) selected candidate study subjects from pregnant women visiting the hospital for prenatal care between May and July 2020, which some six months into the implementation of COVID-19 control measures. She approached the candidate dyads while they were in the waiting area of the Obstetrics Clinic of the hospital on one of their routine prenatal visits. The primary investigator then greeted them both, introduced herself, and talked casually with the dyad first when she visually assessed their overall mental statuses and communication abilities. Should she find the dyad suited for the study, she then explained the purpose and process of the study briefly and asked if both the pregnant woman and her accompanying caregiver were willing to participate. Then the primary investigator checked their eligibility against the inclusion and exclusion criteria. The eligible dyads were included.

The inclusion criteria for the study were: for pregnant women: (1) the pregnancy was uncomplicated; (2) the pregnant woman had a registered prenatal care file at the hospital; (3) the pregnant woman did not have any known serious or chronic physical or mental illnesses; (4) the pregnant woman was aged 18 years or older and had sufficient communication ability; for informal caregivers: (5) the caregiver did not receive financial compensation of any kind for his or her care delivery; (6) the caregiver provided at least eight hours of care daily for the pregnant woman over the last week to qualify as a primary informal caregiver; (7) the informal caregiver had sufficient communication ability and was mentally fit as visually assessed by the primary investigator; for the dyad: (8) the pregnant woman and her primary informal caregiver gave written consent to part-take in the study. The exclusion criteria: for pregnant women: (1) complicated pregnancy; (2) the pregnant woman visited the hospital only for ad hoc prenatal care;

(3) the pregnant woman had one or more serious or chronic disease or was mentally unfit for the study as visually assessed by the primary investigator; (4) the pregnant woman was aged below 18 years or did not have sufficient communication ability; for informal caregivers: (5) the caregiver received financial remuneration of any kind for the care delivered; (6) the caregiver's average daily care time was less than eight hours over the last week; (7) the informal caregiver did not have sufficient communication ability, or was known or observed to be mentally unfit for the study as visually assessed by the primary investigator; (8) the informal caregiver showed any concern or was uncomfortable to talk freely in the presence of the pregnant woman; for the dyad: (9) either one of the dyad refused to participate in the study; and (10) the dyad had a conflicting schedule for interview.

The sample size was determined with the data saturation method (Sandelowski, 1995) , where we stopped enrolling and interviewing new subjects when data saturation was achieved, i.e. when the interviews ceased to yield new analytic information.

Strict COVID-19 precautions were exercised on every inter-personal encounter, including wearing proper masks, handwashing and disinfection before and after, social distancing of at least 1.5 meters, disinfection of used items, and proper disposal of wastes produced during the interviews.

The research team included three registered nurses, each with more than 10 years of clinical experience, one radiologist, and one obstetrician. All members received training on phenomenological research and semi-structured interview. The research team designed the study and developed the interview questions. The primary investigator, who was also a psychological counselor with over five years' experience, conducted semi-structured interviews with the included subjects.

The interviews were situated in a designated meeting room in the Obstetrics Department of the hospital. The room was disinfected and properly aired. The primary investigator interviewed no more than two dyads face-to-face a day for precaution considerations. The informal caregiver was the targeted interviewee while with the pregnant woman was seated in the same room during an interview. The pregnant woman was allowed to add to her carer's response occasionally.

The subjects were invited for an interview right after they were included or after their clinic consultation on the current prenatal visit. After they were seated, the primary investigator explained the study in details and attained their informed consents. The primary investigator then turned on the recorders and began the interview with a grand tour question such as 'Could you describe how you feel about caring for a pregnant woman/your wife/your daughter... during the special time of COVID-19 lockdown?' and 'Have you experienced any changes in caring for a pregnant woman compared with before the epidemic?' Probing questions were asked to encourage the interviewee to elaborate, such as 'Could you tell me more about it?' and 'What would you say is the most difficult problem to deal with?'

Interview techniques such as rhetorical questioning, repetition and response were employed to collect the real psychological feelings of interviewee. The primary investigator took field notes including the interviewee's tone of speaking, notable facial expressions and gestures during the interview. The interviews lasted 27 minutes on average (range 20-32 min). The entire interview processes were audio recorded with two recorders. The recordings and field notes were cataloged right after an interview. The research team transcribed the recordings verbatim and double checked the transcriptions for accuracy within 24 hours after each interview.

All personal identifiers of the subjects were replaced with serial numbers N1, N2... for anonymity.

All data were kept confidential. Information on and recordings of the excluded subjects if any were properly destroyed, except for their demographic information kept for statistical calculations.

The following measures were taken to ensure quality of data: (1) the primary investigator maintained neutrality during interview, who only encouraged or oriented the interviewee when appropriate without giving any personal opinions or making a personal judgment; (2) the primary investigator clarified uncertain statements or feelings with the interviewee during the interview; (3) the transcriptions were emailed to the participants for verification; and (4) the research team resolved doubts or disagreements during transcription review with a discussion based on the original transcriptions and clarified with the interviewee if it remained unresolved.

The data analysis process was based on Colazzie's method, including: (1) the research team members read each interview transcription in entirety to form an overall understanding; (2) the primary investigator worked as the primary coder with the other investigators to analyze and extract significant statements from the transcription; (3) the team encoded and gathered the recurrent statements of significant opinions; (4) the team classified similar codes into more comprehensive sub-themes; (5) the team summarized the sub-themes to form major themes; and (6) the primary investigator double checked with the interviewees to verify accuracy.

As mentioned above, in case there was a disagreement among the team, we would go back to the transcription for clarification. A phone call would be made to the interviewee in question for final resolution if the disagreement remained after the team reviewed the transcription.

Out of 18 candidates approached, we eventually included 15 dyads of pregnant women and their informal caregivers (83.3%), who came to our hospital on routine prenatal visits between May 2020 and July 2020. Three dyads were excluded for a conflicting schedule (16.7%). The informal caregivers were 5 women (33.3%) and 10 men (66.7%) aged 37.2 years on average (range 27 -66 years). The pregnant women's average length of gestation was 26±1.50 weeks (range 10+3 -39+1 weeks), most of who were between 12 and 28 weeks (11, 73.3%). All 15 informal caregivers were immediate family members to the pregnant women, including 10 husbands (66.7%), 3 mothers (20.0%) and 2 mothers-in-law (13.3%). Most of the informal caregivers had an education level of undergraduate or over (10, 66.7%), followed by 3 at the level of high school (20.0%) and 2 primary school or lower (13.3%). Two of the informal caregivers did not give information on their occupations (13.3%). The other 13 participants occupations were diverse, including 3 retired (20.0%), 2 small business owners (13.3%), 2 administrators (13.3%), 2 factory workers (13.3%), 2 freelancers (13.3%), 1 clerk (6.7%) and 1 teacher (6.7%). Table 1 details the demographics of the study subjects. 

We summarised five major themes from the interviews with the informal caregivers, i.e.

(1) informal caregivers experienced increased caregiving burdens;

(2) routines in family life were disrupted; (3) there was lack of accurate information and knowledge; (4) informal caregivers adjusted their roles actively; and (5) informal caregivers showed positive attitudes and coping in a difficult time.

Most informal caregivers indicated a rise in caregiving burdens both physically and mentally.

Caring for a pregnant woman could be difficult and stressful in itself, which was further complicated by the COVID-19 pandemic, lockdown and control measures. The informal caregivers experienced more complex psychological processes and greater pressure in their day-to-day caregiving.

The informal caregivers' physical burdens increased due to impact of the COVID-19 lockdown and control measures. The lockdown effectively prevented access to the external help such as sitters, nannies, family relatives and friends that would otherwise be available to provide or support prenatal caregiving. Participant N4 mentioned: 'Our a'yi (nanny) went back to her hometown. It seems that we have to do all housework for a while as the epidemic goes on'. There were more tasks incurred as a result of the COVID-19 control requirements, in particular disinfection. According to participants N1: 'All items at home must be wiped with alcohol every day'; N2: '(We) must disinfect hands and clothes with disinfectant after coming back home from the hospital'; and N14: 'As my daughter-in-law's gestation gets into the later weeks, we have to come to the hospital for a prenatal check every week. My son works in a facial mask factory. He has to work extra hours every day. Aren't there more things to attend to every time we leave home? Like disinfection and so on. Also put on a hat, wear shoe covers. I have to cook every day. Very busy. Tired, really tired!' Access to prenatal care was considerably more difficult because of the citywide transit suspension, which was not lifted until the later stage of the epidemic. This meant that private vehicles were the only means of transportation to the hospital. Riding a private car was not as simple as before COVID-19 according to participant N15: 'My wife can't ride any public vehicles lately. Every time we leave home it takes half an hour to disinfect the car.' Shutdown of most restaurants, supermarkets, food markets and grocery stores complicated daily care delivery. Participant N7: 'We need to keep changing food tastes. All restaurants and stores are closed outside. I got many recipes but some have failed.'

In face of the COVID-19 pandemic, fear, worry, and anxiety were common, which was especially true when the lockdown first began. According to participant N1: 'I will only feel safe after wiping everywhere every day, feeling safe for my daughter-in-law (pregnant woman) and dear grandbaby ( 

Most participants indicated that their daily routines and original life plans were disrupted because of the rapidly changing epidemic situation recently, which had resulted in changed care tasks and schedule. Shutdown of the local farm product markets significantly reduced the diversity of and access to food supplies, as participant N7 said: 'We can only go to a store to get food lately. There used to be so many fresh vegetables and fruits for us to choose from at will, especially those fresh vegetables from the countryside, which we can't get lately.' Participant N12 also mentioned: 'The food market near our neighborhood is closed because some suspected case was found. Buying food is not convenient.' Ban on crowd gathering and home stay requirements ruled out opportunities of social gathering in person. Outdoor activities such as daily walks and exercises for pregnant women were not allowed or intentionally avoided for fear of the virus. Participant N8 said: 'We don't party recently. It's not convenient for my wife to excise. She exercises completely indoors. The whole family stay in the home for whole days every day'. Participant N13 said: 'My daughter's pregnancy is getting in the late weeks. Shopping is not easy now. Many (shops) are closed. We stay home and can't go for walks in the park. We cook some nice food together and kill time by making some little stuffs.'

Because there was no known knowledge about this newly emerging virus and the conditions that it 

The pandemic and lockdown situation were a stressor that could cause fear, worry and anxiety. However, 'every cloud has a silver lining'. People's behaviors may change positively during the COVID-19 pandemic (Kalra & Deshmukh, 2020) . It also meant more time for the pregnant women and their informal caregivers, in our case family members, to spend closely together, an adversary for the family to confront and go through together, and a rare valuable period for them to rethink their lives and relations. We noted positive attitudes in the participants towards what they experienced personally as an informal caregiver during the lockdown. They also found ways to cope with the difficult time and manage to provide quality care for their wives or children.

When witnessing the disease and deaths during the pandemic, some of the informal caregivers began to look at themselves, life and family from a new perspective than before. There appeared to be positive changes in their attitudes and behaviors. According to participant N4: 'There are so many confirmed COVID-19 cases and deaths every day. (I) find life really unpredictable. I feel truly lucky that we are waiting for a new life to be born in this rather safer environment. I feel the sanctity of life. I'm very grateful...' Participant N6 articulated: 'After confronting the difficulties, (I) am actually not anxious any more. At this point, taking good care of my wife and baby is the most vital thing for me.'

The caring process seemed to bring the relationship between informal caregiver and pregnant woman closer. This was both true for a husband and a parent as an informal caregiver. Participant N15 (husband) told the interviewer that '(We) watch TV series, read books and play video games together. (I) try every way to make her laughter. (I) don't work extra hours recently. (I) don't have pressure or business diners like before. Very quiet life now. We feel very sweet.' Participant N13 (parent) said: 'My daughter and I stay home. We make some small stuffs together while chatting.

(Her father and I) were busy when we were younger. She was busy going to school, graduating, working and getting married. It's rare that we can communicate deeply like this. We find it very valuable.'

When a husband made his wife happy through his caring efforts, he felt a sense of accomplishment, as participant N3 pointed out: '(I) was always busy with work and felt fine to leave her (wife) to the family. But now I cook every day, we watch TV together, chat after eating, and I feel very satisfied. I can really get used to a life like this, very good indeed.' Participant N7 even said proudly: 'Very valuable experience. (My) cooking skills have improved considerably. My wife says I'm pretty good at it now.'

Childbearing is a highly attended life event in Chinese culture. The attention has grown even higher and the way informal prenatal care is delivered has become more diverse and thorough as families are more financially affluent. Special care for a pregnant woman could even start before a planned pregnancy and last beyond child labor. The care tasks range from preparing special food, helping a pregnant woman with daily living activities, accompanying her on a prenatal visit at a hospital to providing personal company and psychological support. Identities of informal caregivers may be one or even more of the couple's parents, who in many cases may move to live with the couple; family relatives and friends, who may or may not receive economic remunerations; and hired external help such as a nanny or sitter. The husbands typically continue to work and may share some care tasks. The number of caregivers engaging in prenatal care, especial how much external help is hired, mostly depends on how affluent the family is.

After the COVID-19 epidemic broke out in December 2019, the usual way of informal prenatal care delivery was disrupted. The nationwide lockdown and other stringent control measures drastically changed the circumstances in which prenatal care was delivered. On one hand, the travel ban prevented most families from attaining external help. On the other hand, extended holidays freed up husbands and other family members for caregiving. As a result, there seemed to be a shift of caregiver identity from a more diverse makeup to more immediate family members. According to our findings, all the interviewed informal caregivers were either parents/parents-in-law or husbands of the pregnant women. The interview findings also revealed that hired help such as 'nannies' had left after the epidemic began. Without external help, fewer caregivers were available per pregnant woman and each caregiver would have to take up more care tasks.

Increased complexity and variety of informal care tasks also added new tasks during the lockdown. Accessibility of prenatal care was troubled because of suspension of urban public transit, which reduced the available options of means of transportation for prenatal visits to a hospital. Limited bus lines were kept for public use, which however were hardly chosen by pregnant women and their family for fear of virus transmission. Private cars seemed to be the most used vehicles according to our findings. Riding it meant more tasks including driving and disinfection before and after. After citywide lockdown began, only a handful of grocery stores and food markets were kept open. Access to food and daily groceries was more difficult and incurred other tasks such as disinfection of all containers, the purchased items and body surface every time a caregiver went for grocery shopping. Daily exercises of pregnant women became more challenging because most public spaces suited for a walk and exercises such as parks and malls were closed, temperature had to be checked at the entrances and exits of residential compounds, and disinfection and facial masks were required. Hospitals were required to devise infection screening and prevention mechanism. The measures included a mandatory online appointment, temperature taking at the entrance of hospital and a double check before entering a clinic, wearing of facial masks at all times, distancing in the waiting areas, disinfection after physical contact, and use of designated space and passage if any sign of COVID-19 infection was detected. This complicated prenatal visits. An accompanying caregiver was more needed than before the pandemic to assist the pregnant women with the visit process. These considerably increased the physical burdens of the informal caregivers according to our findings. The caregivers seemed more stressed psychologically during the lockdown, especial the early stage of the pandemic. As the interviewees indicated, they were fearful, worried/concerned, and nervous. They feared for the transmission and infection of the virus, were worried/concerned because of absence or lack of accurate information and knowledge about the newly emerging disease, and were nervous about the safety of the pregnant women and the babies as well as whether they had done properly in delivering care. The emotional responses during the COVID-19 lockdown added up to their care burdens psychologically. Similar experiences have been reported of other special groups by a number of other researchers during the COVID-19 pandemic (Borges-Machado et al., 2020; Sheth et al., 2021; Penteado et al., 2020; Cohen et al., 2021) There are known strategies that are potentially helpful for easing the informal caregivers' prenatal care burdens. Many of the additional care tasks were resulted from reduced accessibility of prenatal care according to our findings. A modified schedule which requires fewer prenatal visits may minimize the demand of a pregnant woman to access care, in particular those whose gestation is not complicated and only needs routine checks. Compared with the Chinese Medical Association guidelines, which most Chinese prenatal care providers adopt and requires at least ten routine prenatal visits throughout pregnancy, Peahl AF et al. evaluated a reduced prenatal visit schedule incorporating virtual visits (Peahl et al., 2021) . Such a schedule of less frequent visits may not be necessary in times other than disasters like COVID-19, but could lower the need to access a care provider, hence reducing the informal care tasks incurred. Tele-medicine technologies including tele-consultation on a smart phone, remote monitoring and uploading of pregnant woman's vital signs, fetal heart rate and other physiological data, and home-delivery of medications are well developed and widely adopted during the COVID-19 pandemic (Peahl et al., 2021; Fryer et al., 2020; Zork et al., 2020; Pasadino et al., 2020) . Replacing some of the routine physical prenatal visits with the online and remote technologies may well reduce the required frequency of physical access to hospital. A third strategy is to localize some of the routine lab tests and examinations on a prenatal visit. Many of the community health centers were kept operational during China's COVID-19 lockdown. Patient attendance was not allowed but the health workers would make home visits to the households in the local neighborhoods, who were responsible for taking temperature and monitoring for signs of COVID-19 infection, delivering refill medications for the local chronic disease patients, and dealing with simple illnesses. It is suggestible that in future lockdown events, they may also collect blood and other samples of pregnant women and use the local laboratory equipment for certain tests and examinations, saving the pregnant women and their informal caregivers a visit to hospital.

Information dissemination, education and psychological counseling may be helpful for alleviating the informal caregivers' psychological burden. According to our findings, fear for the COVID-19, especially in the early stage of the pandemic, was largely attributable to the absence or lack of accurate information and knowledge about the virus and the disease. There was no known knowledge of the pathogen whatsoever due to its total novelty. Rumors and misinformation were not uncommon in the beginning. The number of infected patients and death toll increasing by the day made it even worse psychologically. It was repeatedly expressed by the participants that accurate information and knowledge were needed, preferably from reliable sources such as health professionals. As an essential part of prenatal visits, pregnancy health education may be an opportunity to offer helpful information and knowledge for easing the informal caregivers' psychological burden. Health professionals involved in prenatal care, both physicians and nursing staff, may contribute by offering information and knowledge. In future disaster situations where a lockdown is likely, health professionals may even act proactively, for instance, by preparing disease knowledge pamphlets to give out on a physical visit and organizing lectures offered to both pregnant women and their caregivers online in addition to their routine pregnancy health education. If a caregiver is psychologically troubled, for example experiencing burnout, professional counseling sessions should be recommended and scheduled.

Local community services may play a valuable part in alleviating informal caregiving burdens during pregnancy. To some extent, the Chinese community services were caught unprepared when first responding to the COVID-19 pandemic. There had never been a nationwide mobilization as thorough as the COVID-19 lockdown. Community services in response to COVID-19 focused on maintaining order of local neighborhood, provisions of daily living necessities and pandemic control measures. The only special population that was specifically targeted was the elderly people, especially those with chronic diseases, to whom refill medications were prescribed online and delivered to their doors. Other special populations including pregnant women and their informal caregivers were treated the same way as the general population. Targeted services should be considered for the groups in future lockdown events. In addition to the healthcare needs mentioned above, other special needs in daily living during pregnancy, such as food and exercise, may also be attended in community services. Furthermore, emergency response measures addressing the needs of different special populations should be specified in future policy making. The efforts may serve their purposes best if done proactively based on the experiences gained from disaster events such as the COVID-19 pandemic and research findings such as the current study.

It is notable that the lockdown was not described only as a negative experience by the informal caregivers. Several interviewees found it an opportunity for them to rethink their lives and family relations; in some cases, a chance to improve the relations by caring for the mothers-to-be. Without external help, immediate family members, especial the husbands who were freed up from work during the extended holidays and stayed home because of the lockdown, became the primary informal caregivers for their pregnant wives. Many of them adapted to their new roles positively. They seemed to enjoy the time spent caring for their wives according to our findings. The message that the lockdown could be 'the silver lining of a dark cloud' may be added to the health education and counseling sessions offered to the informal caregivers, which might allow them to see their heavier caregiving efforts during the lockdown from a positive perspective and react to the increased burdens more optimistically.

As the COVID-19 pandemic continues and mutant viral strains keep emerging, future lockdowns are not impossible. The experiences and potential response measures explored in our study may find merit in similar circumstances and even other disaster situations in China and other countries for individuals, families, healthcare providers, policy-makers and communities to develop strategies proactively for addressing the needs of the informal caregivers. However, the findings of our study should be generalized and applied with caution because prenatal informal caregiving practices may vary significantly from one country to another and there are differences in the national conditions, governing systems, and cultures between societies. Caregivers, researchers, and policy-makers should give full consideration to their local realities when adopting the recommended strategies in response to the COVID-19 lockdown or any other similar disaster event.

Informal caregivers for pregnant women experienced increased caregiving burdens, found their life routines disrupted and their roles in caregiving altered as a result of the COVID-19 lockdown and control measures. Some carers, however, showed positive reactions and saw the period in lockdown as an opportunity to rethink their lives and improve family relations. Several strategies may hold promise for better informal prenatal caregiving in future lockdown events, including adoption of a prenatal visit schedule that requires less frequent physical presence, use of tele-medicine and tele-education technologies, and provision of accurate information and knowledge. Psychological counseling, community services and policies targeting the special populations of pregnant women and their informal caregivers may also be valuable resources. Attention should be drawn to the group of informal caregivers for pregnant women during a COVID-19 lockdown, including professional assistance delivered by nursing and other related professionals. Measures are called for to minimize exposure opportunities such as adoption of a new prenatal care schedule and tele-medicine technologies. Patient education with reliable information should be provided, preferably by nursing staff and physicians. Social support efforts including professional mental counseling may added and work with other resources such as community services and policy makers.
