Abstract

Objectives: To associate the maternal perception of the child’s weight (MPCW) and the child’s nutritional status. To describe child’s lifestyle behavior problems (CLBPs) and maternal self-efficacy (SE) to deal with them, as well as to verify differences according to children with and without overweight-obesity (OW-OB) and MPCW.

Material and methods: There was participation of 274 dyads (mother-preschool child). MPCW was assessed through words and images. The mothers answered the Lifestyle Behaviour Checklist. The child’s weight and height were measured.

Results: 18.8 % (n = 13) of the mothers of children with OW-OB and 78.8 % (n = 160) of the mothers of children without OW-OB obtained adequate MPCW values through words (X² = 77.759; DoF = 1; p < .001). It was identified that the mothers of children with OW-OB reported more CLBPs and less SE. When the child’s OW-OB is perceived through words, there are more CLBPs (F = 17.041; p = .001) and less SE (U = 1,118; p = .015).

Conclusions: Inadequate MPCW was predominant in mothers of children with OW-OB. When OW-OB is perceived, there are more CLBPs and fewer SE. It is recommended to promote adequate MPCW, particularly in mothers of children with OW-OB. Images assist in the identification of the child’s OW-OB more than to classify it into a category.

Introduction

Childhood obesity is one of the most severe public health problems of the 21^st century. Its prevalence has been increasing at an alarming pace. In 2016, more than 41 million children aged less than 5 years old worldwide were overweight or obese ⁽¹⁾. Multiple factors contribute to excess weight during childhood, such as high consumption of fat and sugar and reduced physical activity ⁽²⁾, as well as false traditional beliefs regarding health and nutrition ⁽³⁾.

Excess weight during childhood has repercussions on health, such as hyperlipidemia, hypertension, and abnormal tolerance to glucose. In addition, it has been documented that an overweight 5-year-old child has 4 times more chances of presenting obesity at the age of 9 when compared to a child with normal weight at the same age ⁽⁴⁾.

During childhood, and according to the traditional gender role, the mother is the main caregiver ⁽⁵⁾, the reason why she is in a unique position to exert an influence on her child’s lifestyle behaviors. However, the literature has documented that the mothers of overweight-obese children have an inadequate perception of the child’s weight: they underestimate it ^(6-10). Therefore, they could be less willing to motivate them to participate in healthy behaviors and less likely to resort to health services ⁽⁶⁾. Likewise, it has been documented that the mothers of children aged between 2 and 6 years old present more chances of underestimating overweight and obesity in their children ⁽⁹⁾.

Assessing how the mother perceives her child’s body weight is a previous step to involving her in programs to prevent and treat excess weight in childhood. The maternal perception of the child’s weight (MPCW) is the mother’s opinion regarding the child’s body weight, formulated based on the recognition of body size, standards related to body weight, health and beliefs associated with upbringing ⁽¹¹⁾.

In addition, it has been documented that mothers of children with overweight-obesity need to deal with the children’s lifestyle behavior problems (CLBPs) linked to childhood obesity, such as: demanding extra helpings at meals or watching too much television; and they report less self-efficacy (SE) to deal with these problems when compared to the mothers of children with normal weight ^(12-14). Self-efficacy allows the caregiver, in this case, the mother, to perceive her own ability and competence to exert a positive influence on the children’s behaviors, upbringing and development. The concept of self-efficacy was proposed by Bandura in 1977 as a core cognitive element to explain the acquisition, maintenance and changes of human behavior, along with other variables of the Social Cognitive Theory ⁽¹⁵⁾.

As already pointed out, most of the mothers of children with overweight-obesity present inadequate MPCW; in addition, they have fewer chances of participating in programs to lose weight ⁽⁶⁾, as well as less motivation to help the children reduce their body weight and foster healthy behaviors ⁽¹⁶⁾. On the other hand, several studies conducted with adolescents and adults have found that an adequate perception of overweight-obesity is associated with depression and with unhealthy behaviors that could favor weight gain ⁽¹⁷⁾. However, up to date, it has not been explored if the CLBPs and SE to deal with them differ according to an adequate maternal perception of overweight-obesity in preschool children.

Given the above, this research study was conducted with the following objectives: 1) to associate MPCW with the child’s nutritional status, 2) to describe the CLBPs and verify if they differ according to children with and without overweight-obesity, 3) to describe SE and verify if it differs according to children with and without overweight-obesity; and 4) to evaluate if the CLBPs and SE differ according to MPCW.

Given that Nursing is the first contact of the user with the health services, it is considered that the knowledge that is generated could ground Nursing actions targeted at preventing and treating childhood overweight-obesity, promoting adequate MPCW, and implementing actions targeted at reducing the CLBPs that are identified, as well as offering strategies to strengthen SE to deal with them.

Material and methods

Design

A correlational and cross-sectional study.

Inclusion criteria

Women who identified themselves as mothers of preschool children enrolled in the selected educational institutions.

Women who were able to read and write to answer the questionnaires.

Exclusion criteria

Questionnaires in which the mothers reported that the preschool children had some diseases affecting their development, such as endocrine disease and asthma.

Participants and Sample

The participants were preschool children and their mothers, the latter being recruited for having their children enrolled in 4 public educational institutions attended by 524 preschoolers. Recruitment was conducted in 2016 and the institutions belonged to School Zone No. 1 of the metropolitan area of Monterrey, Nuevo León, Mexico. The zone was randomly selected from the list provided by the Public Education Secretariat.

To calculate the sample, the nQuery Advisor package, version 4.0, was used for means comparison of SE according to MPCW with and without OW-OB, a bilateral significance level of .05 and power of 95, which resulted in 270 participants. Subsequently, using cluster-stratified sampling, where the schools were the strata and the groups were the clusters, the groups were randomly selected, and 300 mothers were invited to participate. A total of 274 dyads (mother-preschool child) were considered for the analysis; the questionnaires in which the mothers reported that the children had some disease (n = 8) were excluded, as well as incomplete questionnaires (n = 12) or those with duplicate answers (n = 6).

Study Variables and Measurements

MPCW was the mother’s perception regarding her preschool child’s weight, which was assessed through two methods. In the first, called perception through words, the mothers answered the following question: “I believe that my child is”, with the following answer options: a) “underweight”, b) “slightly underweight”, c) “around normal weight”, d) “slightly overweight”, and e) “overweight”. This corresponds to the Physical Appearance and Health Perceptions Questionnaire ⁽¹⁸⁾; it was considered adequate when the mother’s report was in agreement with the nutritional status assessed in the child ⁽¹⁹⁾. It is worth noting that, in the mothers of children with overweight-obesity, when inadequate MPCW is present it corresponds to underestimation; regarding the mothers of children with low or normal weight, it can present underestimation or overestimation.

In addition, MPCW was assessed through images with a panel containing 7 images according to the child’s gender and age ⁽¹⁸⁾. It was considered adequate when a) the mothers of children with low weight selected images 1 and 2 to the right, b) the mothers of children with normal weight selected images 3, 4, or 5 in the center, and c) the mothers of children with overweight-obesity selected images 6 or 7 to the left.

The mothers also answered the Lifestyle Behaviour Checklist questionnaire ⁽¹²⁾, which presents 25 different child’s lifestyle behaviors related to childhood obesity. They are asked to indicate to what extent each of these behaviors represents a problem, for example: demands extra helpings at meals, with Likert-type answers, namely: 1) Not at all, 2) and 3) A little, 4) Somewhat, 5) and 6) Very much, and 7) A lot, with a minimum score of 25 and a maximum score of 175, where higher scores indicate that the behavior is perceived as a problem.

Subsequently, they are asked to select from 1 to 10 to indicate how confident they feel to deal with each of the behaviors, where 1 represents no confidence and 10 means feeling confident. In case the behavior is not occurring, they are asked to indicate how confident they feel that they could deal with it if it did occur; the minimum score is 25 and the maximum score is 250, where higher scores represent greater self-efficacy. This questionnaire has reported Cronbach’s alpha values of 0.97 for the BP subscale and 0.92 for the SE scale.

Preschooler nutritional status was the preschool child’s Body Mass Index classified in percentiles according to what is set forth by the WHO ⁽¹⁹⁾, namely: malnutrition (< percentile 3), low weight (≥ 3 and < 15), normal weight (≥ 15 and < 85), overweight (≥ 85 but < 97) and obesity (≥ 97). Weight was measured in kilograms with a 0.1 kg precision Seca 804 scale and was divided by the square of the height expressed in meters, which was measured with a Seca 214 stadiometer. In addition, sociodemographic information such as maternal age, schooling and occupation was asked, as well as the child’s age and gender by requiring the presentation of a sociodemographic information card.

Data analysis

The data were captured and analyzed in the Statistical Package for the Social Sciences (SPSS) for Windows statistical program, version 21.0. The reliability of the Lifestyle Behaviour Checklist questionnaire ⁽¹²⁾ was assessed using Cronbach’s alpha coefficient and the descriptive statistics of the sociodemographic information were obtained.

For Objective 1 (to associate MPCW with the child’s nutritional status), a 2x2 contingency table was prepared with adequate and inadequate MPCW and the child’s nutritional status according to children with and without overweight-obesity, and the chi-square test was applied. For Objective 2 (to describe the CLBPs and verify if they differ according to children with and without overweight-obesity), Objective 3 (to describe SE and verify if it differs according to children with and without overweight-obesity) and Objective 4 (to evaluate if the CLBPs and SE differ according to MPCW), the distribution of the CLBPs and SE variables was verified using the Kolmogorov-Smirnov test with Lilliefors correction and, according to this, parametric and non-parametric statistics were applied.

The single-factor ANOVA test was applied for Objective 2. According to Objective 3, the Mann-Whitney U test was applied and, according to Objective 4, the sum of CLBPs and SE was considered; in addition, the single-factor ANOVA test and the Mann-Whitney U test were applied, respectively.

Ethical considerations

This research was reviewed and approved by an Ethics Committee, registered with No. 12CEI19039007 at the Federal Commission for the Protection against Health Risks, and observed the Ethical Standards outlined in the 1973 Declaration of Helsinki.

The participating mothers were explained the research objectives and the procedures to be performed, as well as the risks and benefits inherent to participation in the study. They were guaranteed freedom to withdraw their consent at any time of the study, without this representing negative consequences for them or their children. Anonymity and confidentiality of the information were ensured, in addition to guaranteeing that the data would only be analyzed and handled jointly; subsequently, the mothers signed the informed consent. Assent was also obtained from the preschool children to perform the anthropometric measurements, which were in charge of qualified and standardized health staff that preserved the preschool children’s integrity and privacy. Data collection was conducted in educational institutions.

Results

The internal consistency of the two subscales of the Lifestyle Behaviour Checklist ⁽¹²⁾ was assessed using Cronbach’s alpha coefficient; both subscales presented acceptable reliability: CLBPs, α = 0.78 and SE, α = 0.94.

There was participation of 274 dyads (mother-child), with a mean maternal age of 30.79 years old (SD = 5.9) and a mean schooling of 11.19 years of study (SD = 3.01); 82.5 % (n = 226) lived with their partner; and 62.4 % (n = 171) were housewives. Regarding the children, their mean age was 4.38 years old (SD = 0.69), 54.4 % (n = 149) were female, mean weight of 18.90 kg (SD = 3.66), mean height of 108.83 cm (SD = 6.80), and 25.2 % (n = 69) with overweight-obesity; the information is presented in Table 1.

Statistics to verify the study objectives

According to Objective 1, adequate MPCW through words was found in 18.8 % (n = 13) of the mothers of children with overweight-obesity and in 78.8 % (n = 160) of the mothers of children without overweight-obesity (X² = 77.759; DoF = 1; p < .001). Through images, adequate MPCW was found in 2.9 % (n = 2) of the mothers of children with overweight-obesity and in 44.4 % (n = 91) of the mothers of children without overweight-obesity (X² = 39.638; DoF = 1; p < .001); the information is presented in Table 2.

Discussion

This study assessed MPCW, as well as the CLBPs and SE to deal with them, and it was verified if they differ according to MPCW. It was found that most of the mothers of children with overweight-obesity present inadequate MPCW, perceive more CLBPs and have less SE. When the perception of the child’s overweight-obesity is adequate, higher CLBP scores and lower SE values are presented.

As already mentioned, inadequate MPCW was present in most of the mothers of children with overweight-obesity, which indicates that they underestimate their children’s weight. This finding is consistent with what is reported in other studies and systematic reviews of studies conducted in countries such as Australia, Germany, Italy, United States, Brazil, United Kingdom and Singapore, among others (7-10). Therefore, the results of this study confirm the existing evidence.

The CLBP and SE variables were assessed using the Lifestyle Behaviour Checklist questionnaire ⁽¹²⁾, which presented acceptable internal consistency, similarly to what is published in the literature regarding the population living in Australia ⁽¹³⁾, the Netherlands ⁽¹⁴⁾ and Mexico ⁽²⁰⁾. It is worth pointing out that, to the present day regarding research, this questionnaire is the only one that assesses SE to deal with CLBPs; likewise, the authors have indicated that assessing self-efficacy for a specific behavior is the best SE indicator, which would allow working to reinforce it ⁽¹⁵⁾.

It was found that the mothers of children with overweight-obesity reported more CLBPs and less SE when compared to the mothers of children without overweight-obesity, which is similar to a study conducted with mothers of children aged from 4 to 11 years old living in Australia ⁽²¹⁾. However, a study conducted in the Netherlands with mothers and fathers of children aged from 3 to 13 years old ⁽¹⁴⁾ and another study conducted in Sweden with mothers and fathers of preschool and school children ⁽²²⁾ found that the mothers of children with overweight-obesity obtained the highest scores in the CLBPs subscale, whereas in the SE scale, no significant difference was identified according to the groups with and without overweight-obesity

Regarding the individual analysis by items, the mothers of children with overweight-obesity presented higher scores in 10 of the 25 CLBPs. It is worth noting that the study conducted in Sweden ⁽²²⁾ identified a significant difference in 20 out of 25 CLBPs, and that the survey conducted in Australia ⁽²¹⁾ did so in 24 out of 28 CLBPs. Lower scores were identified in 15 of the 25 SE items in mothers of children with overweight-obesity. The study conducted with mothers in Sweden ⁽²²⁾ identified a significant difference in 7 out of 25 items and, in Australia ⁽²¹⁾, there was a significant difference in 26 out of 28 items.

Among the Mexican mothers of children with overweight-obesity, the CLBP that obtained the highest score was that of watches too much television, followed by eats too quickly. For the Australian ⁽²¹⁾ and Swedish mothers, the highest scores were in eats too much and watches too much television ⁽²²⁾. Regarding SE, in the Mexican mothers the lowest score was in the demands extra helpings at meals item and, for the Australian ⁽²¹⁾ and Swedish mothers, it was eats too much ⁽²²⁾. These findings have important implications, since one of the main factors related to excess weight is the increased consumption of calories, a factor that was not pointed out by the Mexican mothers, who, in addition, present less SE when their children demand extra helpings at meals.

Likewise, it was found that, when the perception of the child’s overweight-obesity is adequate, higher CLBPs scores and lower SE values are presented; the aforementioned when MPCW is evaluated through words. A possible explanation as to why no difference was found between the CLBPs and SE variables and MPCW through images is that the latter was assessed with a panel consisting in 7 images, which do not represent categories defined by body weight. In addition, the mothers of children with overweight-obesity could select 2 possible options for MPCW to be adequate ⁽¹⁸⁾.

Other authors point out that, up to date, the best method to assess MPCW has not yet been established, and add that images are useful to help sensitize the parents regarding excess weight in childhood ⁽²³⁾. However, as these images are not shown to the parents along with weight categories, they do not allow them to recognize the child’s weight in a category, as is the case with MPCW through words.

This finding is significant and further exploration is recommended, since the studies conducted in adolescents and adults have found that, when there is an adequate perception of overweight-obesity, depression and lower quality of life can emerge ⁽¹⁷⁾. Likewise, although the recommendation is to promote adequate MPCW in mothers of children with overweight-obesity, it is necessary to explore if, when more child’s CLBPs and less SE to deal with them are perceived, depression and stress could emerge, variables related to unhealthy upbringing practices and to childhood obesity ⁽²⁴⁾.

In addition, the literature indicates that the mothers who feel sufficiently confident to achieve the expected outcomes might not initiate actions or get involved in programs targeted at preventing and treating excess weight in their children ⁽²⁵⁾. A negative and significant relationship has also been documented between SE, restrictive eating practices, and pressure to eat ⁽²⁶⁾, which could result in children gaining weight.

Among the strengths of this study, we can point out that the children’s nutritional status was obtained from the Body Mass Index measured and that the Lifestyle Behaviour Checklist questionnaire ⁽¹²⁾ showed acceptable internal consistency. One of the limitations is that only mothers participated; therefore, seeking the fathers’ contribution is an opportunity area ⁽²⁷⁾. In addition, this study did not identify determining factors of adequate MPCW in the mothers of children with overweight-obesity, as well as it did not analyze if some maternal-child sociodemographic characteristics were related to the CLBPs and to SE to deal with them.

Conclusions and recommendations

It is concluded that the mothers of children with overweight-obesity present inadequate MPCW, underestimate their children’s weight, report more CLBPs in the children and less SE to deal with them. Likewise, when overweight-obesity in the child is perceived, more CLBPs are presented, as well as less SE to deal with them.

It is recommended to replicate this study in other populations with children belonging to a broader age group, as well as to explore the relationship between the perception of the child’s overweight-obesity and variables such as depression, stress, eating habits, and physical activity. It is also suggested to study the relationship between self-efficacy and the promotion of healthy habits in the family, a situation that was not assessed in this research. Finally, it is also recommended to devise interventions to promote adequate MPCW and maternal acknowledgment of excess eating as a factor related to childhood obesity, mainly in mothers of children with overweight-obesity, in addition to strengthening SE to initiate actions targeted at preventing and treating excess weight in childhood.

The authors declare no conflict of interest.
