BACKGROUND: Few studies have investigated the association between alcohol use, intimate partner violence, and HIV sexual risk behavior among young people in fishing communities from eastern and central Uganda. Therefore, we aimed to determine the association between alcohol use, intimate partner violence, and HIV sexual risk behavior among young people in the fishing communities on the shores of Lake Victoria, in Uganda. METHODS: We conducted multivariable logistic regression analyses of HIV risk behavior using cross-sectional data from 501 young people from Mukono (Katosi landing site) and Namayingo districts (Lugala landing site). RESULTS: Almost all (97%) respondents reported at least one HIV risk behavior; more than half (54%) reported engagement in three or more HIV risk behaviors. Results from the adjusted model indicate that alcohol use, working for cash or kind, being married, and having multiple sexual partners increased the odds of HIV risk behavior. IPV was not associated with HIV risk behavior. CONCLUSION: Interventions to promote consistent condom use and fewer sexual partnerships are critical for young people in the fishing communities in Uganda.

disproportionately burdened by HIV, relative to the general population in the country [8] [9] [10] [11] [12] . Specifically, HIV prevalence in fishing communities is estimated to be 5-7 times higher than in the general population [13] . One study estimated the HIV prevalence among people aged 18-24 years in fishing communities along the shores of Lake Victoria to be 12% in men and 26% in women [10] . Despite the high burden of HIV infection in Uganda's fishing communities, HIV prevention and treatment strategies have not effectively reached all high-risk individuals in these communities [10, 14] . One of the largest barriers to HIV service access in Uganda's fishing communities is that these areas are characterized by complex sexual networks that include fishermen, food vendors, fish traders, alcohol brewers, and other service providers [9] . The members of this network are hard to track and follow due to their inconsistent patterns of mobility, the time they spend away from home, their pursuit of a daily cash inflow, and their risky work environments.

Another defining feature of Uganda's fishing communities is the high level of availability and use of alcohol, a well-established risk factor for HIV globally [15, 16] and among young people in fishing communities [17] . Alcohol use impairs judgment, reduces one's ability to negotiate for safer sex, and lowers inhibitions [10] . Kuteesa and colleagues (2020) observe several drivers of alcohol use among fishing populations including work-related stress, mobility, geographical remoteness, and limited regulation of alcohol sales [17] . Evidence from fishing communities in Koome Islands in Mukono District in Uganda indicates that lower education, smoking, and depression are all associated with alcohol misuse [17] . In fishing communities in Tanzania, alcohol consumption is associated with higher odds of contracting HIV [12] . Relatedly, people employed in alcohol-related businesses (e.g., working in bars) in fishing communities around Lake Victoria are at greater risk of HIV infection [18] .

Intimate partner violence (IPV), including physical and sexual abuse, is a risk factor for HIV acquisition [14, 19] , including in fishing communities in Rakai, Uganda [20] . Sexually or physically abused women are less likely to be able to negotiate safer sex with a partner and are more likely to engage in sexual relations in exchange for money or gifts [21] . In the event of a divorce, Kher (2008) notes that women may become vulnerable and susceptible to violence since they lack financial independence and may need to stay in unsafe relationships for survival [14] .

Several demographic, socio-economic, and behavioral factors are associated with sexual HIV risk among Uganda's fishing communities. Asiki et al. (2011) observe that age, occupation, relationship to head of household, knowledge of partner's HIV status, alcohol consumption, inconsistent condom use, marital status, being away from home for more than two nights in a month, gift exchange for sex, multiple sexual partners and a recent history of STIs were associated with sexual HIV risk among fishing communities of Lake Victoria in Uganda [10] .

Age is a key variable that is associated with sexual HIV risk behavior [13, 22, 23] . Kiwanuka et al. (2014) report that HIV incidence is higher among younger people (age 18-24 years) than those age 30 years and older, in fishing communities around Lake Victoria in Uganda [23] . Adolescents are more susceptible to drug and substance abuse, sexual HIV risk behaviors [17] . Studies that focus on fisherfolk are timely because fishing populations are more vulnerable than other risky sub-groups. Kissling and colleagues (2005) observe that sexual HIV risk infection was higher among fisherfolk than other high-risk populations in DRC, Kenya, and Uganda, including sex workers, prisoners, migrant workers, men who have sex with men, military, long-distance truck drivers and drug users. In addition, alcohol consumption is common among young people. They often use alcohol to cope with daily stresses in life makes hence becoming more vulnerable through increased sexual risk taking behaviors [10, 15] .

Multiple sexual partnerships among men is a sexual HIV risk behavior factor. This is higher in fishing communities than in agrarian or trading communities in Rakai Community Cohort Study (RCCS) [24] . This finding resonates with Kapesa et al. (2018) , who found a similar resulthigher odds of being HIV infected among fishing communities around Lake Victoria, northwestern Tanzania (three times higher) than among farming communities. Sexual HIV risk was also observed to be associated with lower levels of education, inconsistent use of the condom, and being older [12] . Results from eight fishing communities in Uganda also indicate higher sexual HIV risk among lower educated people, women, divorced or in multiple sexual relations, and users of alcohol or illicit drugs before sexual encounters [22, 23] .

Some studies have included fishing communities in Gerenge [25] , Kasenyi & Kigungu [18] , and Rakai district [20, [26] [27] [28] , in central Uganda and Kasensero from southwestern Uganda [29] . Despite the well-established burden of HIV in this setting, there is limited research exploring the correlates of sexual HIV risk factors in fishing communities among adolescents and young people in Mukono and Namayingo Districts of Uganda [9, 10, 30] . This paper fills this gap by examining sexual HIV risk factors among young people in the age group 15-24 years in fishing populations in Mukono and Namayingo districts, Uganda. Specifically, we investigate whether alcohol use and IPV influence sexual HIV risk. We focus on this specific age group because they are at the greatest risk of incident HIV [8, 18] . Our contribution to the field of sexual HIV risk is that this paper utilizes data from fishing communities to shed light on the correlates of sexual HIV risk among young people (15-24 years) in Uganda.

A cross-sectional survey was conducted in two fishing communities in Eastern Uganda. Initially, a sequential explanatory mixed methods research design was planned; a quantitative survey to be followed by a qualitative exploration of quantitative findings. Due to the COVID-19 lockdown and travel restrictions that were enacted in Uganda on March 18, 2020, data collection stalled until it could safely be resumed in July 2020. This disruption resulted in a need to adapt the study design, leading us to concurrently collect our qualitative and quantitative data. This manuscript presents findings from the quantitative survey component.

We selected two fishing communities along the shores of Lake Victoria for inclusion in our study: Lugala from Namayingo District (Eastern Uganda), and Katosi landing site from Mukono District (Central Uganda). The rationale for selecting these areas was the scarcity of research evidence from these sites. We used the 2014 Uganda Population and Housing Census (UPHC) sampling frame by the Uganda Bureau of Statistics (UBOS) to select sub-counties, parishes, and enumeration areas, which were fishing communities. For Mukono District, we randomly selected Katosi Town Council (formerly belonged to Ntenjeru Sub-county, until 2019), Nsanja Parish, and eight enumeration areas. For Namayingo District, we selected Banda Sub-county, Lugala Parish, and eight enumeration areas. At the time of data collection, one of the villages was submerged from Lake Victoria flooding, so it was excluded. In total there were seven enumeration areas. At each enumeration area, a sampling frame of eligible households was constructed with the aid of local council leaders from where study participants were selected.

Using Kish's formula as cited elsewhere [31] , we estimated a sample size of 202 participants per study site and a total sample size of 404 young people (15-24 years) from the two study sites. But in actual practice, the total sample size was 501. We aimed to sample nearly the same number of participants from each sampled district because we did not have the population sizes of the landing sites since these are highly migrant and mobile populations [32] . For the sample size calculation, we made an assumption of 50% HIV risk behavior obtained from a recent study [20] , implying that p = 0.50 and q = 0.50, confidence level of 95%, error term of 10%, design effect of 2, and non-response of 5%. The final selection of study participants was done using simple random sampling. A pre-test of data collection tools was conducted at the Ggaba fish landing site on the shores of Lake Victoria in Kampala district in June 2020. We were able to revise the flow of few survey questions and identify those that were not clear to the respondents in terms of translation. Most of the survey questions were fine. Therefore, data collection was conducted in July 2020.

Men and women age 15-24 years with a history of sexual activity were eligible for participation. Participants without a history of sexual activity were excluded because most key questions focused on IPV and HIV risk behavior and were exclusive for those who have never had a sexual partner in their lifetime. We used screening questions on the consent form that indicated whether the potential respondents had ever had sex in their lifetime.

Quantitative survey data were collected by research assistants using electronic tablets using an Open Data Kit (ODK) or Survey CTO platform [33] . A survey questionnaire was used (Supplementary File 1). Research assistants were trained for three days (July 6-8, 2020). Trained research assistants collected the survey data using the personal interview method. The selected research assistants knew the local languages (Lusamia, Lusoga, Luganda). Data collection was conducted in the local languages using translated survey tools. We performed a back-and-forth translation from English to the local languages. First, the tools were translated from English to the local dialects by professional native language speakers. Second, during the training of research assistants and role-plays, the translated tools were used. During the pre-test, language issues were checked. During the de-briefing with research assistants, translations were revised. When the research assistants arrived at the households, they requested a secluded place to ensure privacy. All data were exported to STATA for statistical analysis [34] .

HIV sexual risk behavior was measured using the HIV-Risk Screening Instrument (HRSI) [35] . The HSRI contains 10-item binary questions about multiple sexual partnerships, condom use, sexually transmitted infections (STIs), transactional sex, and substance use. Although the instrument was designed for healthcare settings, it was recommended for testing and application to the general population.

During exploratory data analyses, HIV risk measures were tested for correlation. Two pairs of the ten items were strongly correlated. First, items four and ten (respondent's self-reported STIs and partner's self-reported STIs respectively) had a positive correlation (r = 0.49). Second, items seven and eight (injecting drug use by respondent and partner's injecting drug use respectively) were also positively correlated (r = 0.44). The reliability test score was 0.51.

An aggregate score of HIV risk was generated from the 10-items (mean HIV risk score = 2.87, standard deviation (SD) = 1.61, range = 0-10), for use in additional statistical analyses. Exploratory data analysis using a histogram portrayed a normal distribution of the HIV risk score. The minimum score was 0 and the maximum was 8. The HRSI recommended that a threshold of participating in at least one HIV risk item is sufficient for high-risk populations [35] . However, 97% reported at least one HIV risk behavior. This would create a common outcome. Therefore, we created a binary categorical variable for HIV risk behavior from the HIV risk score at the mean HIV risk score of 3. HIV risk behavior was recorded as participating or reporting three or more of the ten HIV risk screening items or behaviors.

IPV was measured using validated screening tools: the Hurt, Insult, Threaten, and Scream (HITS), the Woman Abuse Screening Tool (WAST), and the Abuse Assessment Screen (AAS) tools [36] [37] [38] . For men, the WAST questions were modified to reflect the perpetuation of violence. The HITS tool has four questions with the following response categories (1 = Never, 2 = Rarely, 3 = Sometimes, 4 = Fairly often, 5 = Frequently): a) How often did/does your partner physically hurt you? b) How often did/does your partner insult you or talk down to you? c) How often did/does your partner threaten you with harm? d) How often did/does your partner scream or curse you?

The four items were reliable measures for IPV (Chronbach's alpha = 0.88). The mean HITS score was 7.2 (SD 4.1, range = 4-20). There was a strong positive correlation among the four items. A score of 10.5 and higher is regarded as a positive response to IPV [38, 39] . Therefore, we created a binary variable for HITS to be a yes, if the HITS score was 10.5 and higher and to be a no, otherwise.

The WAST tool has eight questions, which are also described elsewhere [36, 38, 40] . a) In general, how would you describe your relationship with your partner? b) Do you and your partner work out arguments with great difficulty, some difficulty, or no difficulty? c) Do arguments ever result in you feeling down or bad about yourself? d) Do arguments ever result in hitting, kicking, or pushing? e) Do you ever feel afraid/frightened by what your partner says or does? f) Has your partner ever abused you physically? g) Has your partner ever abused you emotionally? h) Has your partner ever abused you sexually?

The first two questions (a-b) are regarded as the WAST-short form (WAST-SF). The first question (a) has the following response categories (1 = No tension, 2 = Some tension, 3 = A lot of tension). The second question (b) uses the response categories (1 = No difficulty, 2 = Some difficulty, 3 = A lot of difficulty). The last six questions (c-h) have the following response categories (1 = Never, 2 = Sometimes, 3 = Often). Exploratory analyses showed that the eight items were reliable (Cronbach's alpha 0.89). The mean WAST score was 11.56 (SD 4.54, minimum 8, and maximum 24). To generate an IPV variable from the eight items, it is recommended that a score of 13 and higher (range = 8-24) is used to denote IPV or abuse [36, 38, 40] . Therefore, we generated a binary WAST variable to measure IPV (yes = WAST score > 13 and no = WAST score [8] [9] [10] [11] [12] .

For the AAS tool, we used two binary questions instead of five questions [38] . The two questions were: a) In the past 12 months, were you emotionally or physically abused by your partner? b) In the last 12 months, has anyone or your partner forced you to have sexual activities against your will?

We excluded three questions that were already captured in the HITS and WAST tools. For the AAS tool, any positive response to any question denotes IPV [38] . Therefore, we created a binary IPV measure from the two questions if a respondent responded in the affirmative (yes) to any of the two binary questions.

Alcohol use was measured using the WHO's Alcohol Use Disorder Identification Tool (AUDIT) [41] [42] [43] [44] [45] [46] [47] [48] [49] [50] . It has 10 questions (response categories from 0 to 4). An AUDIT score was generated by a summation of all ten items. The minimum score was 0 and the maximum was 40. The mean AUDIT score was 2.5 (SD = 5.5) because it was affected by the non-drinkers. Studies in Australia recommend that to create AUDIT categories, AUDIT scores of 0 is for non-drinkers, 1-7 denotes "low-risk drinkers", 8-12 denotes "at-risk drinkers", 13-19 represents "high-risk drinkers, and 20-40 means "dependent drinkers" [44] . Therefore, we created a categorical AUDIT variable following these guidelines.

Demographic and socio-economic variables included district of residence (Mukono and Namayingo), sex (male or female), age group [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] , an education level (None, Primary, Secondary or Higher), employment status (Yes, No), religious affiliation (Catholic, Anglican, Pentecostal, Muslim and others), children ever born or ever given birth or fathered a child (yes or no), and marital status (never married, married, living together, formerly married). Partners' characteristics included education (None, Primary, Secondary or Higher), how often the partner got drunk with alcohol (yes or no), and whether their partners accused them of having other sexual partners in their lifetime or recently (yes or no).

Frequency distributions were used to analyze the descriptive characteristics of the respondents. Chi-square tests were used to measure the association between HIV risk and alcohol use, measures of IPV, and selected explanatory variables. Multivariate logistic regression was used to estimate the relationship between HIV sexual risk behavior as a binary outcome and alcohol use, IPV, and variables that had a 10% or less significant association with the outcome variable [34, 51] .

Two models were estimated. First, HIV risk was regressed against alcohol use and IPV as primary covariates (unadjusted model). Second, HIV sexual risk behavior was regressed against the two primary covariates (alcohol use and IPV) while controlling for demographic (age, sex, marital status, children ever born), socioeconomic factors (education level, employment status), and behavioral factors. Regression diagnostics included the use of the link test to determine the goodness of fit of the models. Also, pairwise correlation and collin commands were conducted to ascertain possibilities of multicollinearity among the covariates.

Descriptive characteristics Table 1 shows the descriptive characteristics of the respondents. There was an even distribution of respondents from Mukono and Namayingo districts. More than half (61%) were female, and three-quarters (75%) were age 20-24 years (mean age of 21.1 years, a standard deviation of 2.4 years).

The majority (45%) of the young people had primary education and six in ten (65%) worked for payment in the last 12 months. A quarter (25%) of them were engaged in petty trade and a small proportion (18%) participated in fishing activities. Catholicism was the most widely practiced religion (40%). More than half (70%) were married and 12% were formerly married. Over two-thirds (72%) had ever given birth or fathered a child. Nearly all respondents (94%) had sexual partners in the last 12 months.

Forty percent of the young people had partners who had achieved secondary or higher education. More than half (53%) had lived in a relationship for between one and three years (mean duration was 1.9 years and standard deviation of 0.7 years). A quarter (26%) reported that their partners consumed alcohol. Four in ten (44%) of the respondents had or were accused of having other sexual partners by the current partner. More than half (64%) used two or more methods to prevent HIV in the last three months. Nearly all respondents (99%) had comprehensive knowledge about HIV transmission and prevention mechanisms. Table 1 also shows the prevalence of alcohol use, IPV, and HIV risk behaviors. The mean AUDIT score was 2.5 (standard deviation of 5.6). Nearly four in ten (39%) were alcohol drinkers. Of those who drunk alcohol, a quarter (27%) were low-risk drinkers and 12% were risky drinkers.

The prevalence of IPV in the last 12 months was 21% using the HITS scale, 40% using the WAST scale, and 63% using the AAS scale. Almost all (97%) respondents reported at least one HIV risk behavior, and more than half (54%) of the respondents reported three or more HIV risk behaviors. Figure 1 shows the HIV risk screening tool items. Almost all (97%) of the respondents reported at least one or more HIV risk behaviors. The most common HIV risk behaviors were non or inconsistent condom use (80%), being sexually active (70%), self-reported STIs (40%), multiple sexual partnerships (28%), and selfreported STIs by partner (22%). Table 2 shows the association between HIV risk behaviors and selected explanatory variables. In bivariate analysis, there were no significant differences in the prevalence of three or more HIV risk behaviors by district, age category, education level, religion, and partner's education level. The prevalence of HIV risk was higher among males compared to females (60% vs 50%; p = 0.04). HIV risk behavior was highest (60%; p = < 0.001) among respondents who worked and received payment in cash or kind and depended on fishing (67%; p = < 0.001) as their source of livelihood. Furthermore, HIV risk behavior was highest among respondents who were married (68%; p = < 0.01) and ever gave birth or fathered a child (58%; p = < 0.01). Those who drank alcohol reported three or more HIV risk behaviors (65%; p = 0.02). Respondents who prevented HIV in two or more ways had lower HIV risk behaviors. Table 2 also shows the association between HIV risk and alcohol use and IPV measures. The prevalence of HIV risk behaviors was higher among those who drunk alcohol compared to those who did not (63% vs 48%; p < 0.01). There was some difference in the prevalence of HIV risk among those that experienced IPV by HITS scale compared to those who did not (63% vs 52%; p = 0.05). The prevalence of HIV risk was higher among those who experienced IPV by the WAST scale compared to those who did not (61% vs 50%; p = 0.02). The prevalence of HIV risk was higher among those who experienced IPV by the AAS scale compared to those who did not (58% vs 47%; p = 0.02). Finally, experiencing IPV by HITS or WAST or AAS was associated with a higher prevalence of HIV risk (57% vs 47%; p = 0.02). Table 3 shows the multivariable logistic regression models fit to identify factors associated with HIV sexual risk behavior. The key correlates of HIV risk were alcohol use, working for payment in cash or kind, being married, and having other sexual partners. However, IPV was associated with HIV sexual risk behavior at the bivariate level, not at the multivariate level.

Alcohol use was associated with increased odds of HIV risk at bivariate (OR = 1.83, 95% CI: 1.27-2.65), and multivariate analyses (aOR = 1.83, 95% CI: 1.18-2.85) respectively. When IPV measures were added in model 2, there was no change in effect sizes (both adjusted odds ratios and significance levels) for alcohol use. Slight changes in effect sizes for alcohol use were realized when we adjusted for socioeconomic factors.

Working for payment in the last 12 months increased the odds of HIV risk (aOR = 2.13, 95% CI: 1.30-3.49). Being married was associated with increased odds (aOR = 2.29, 95% CI: 1.08-4.86) of HIV risk compared to being never married. Finally, being accused by the partner or having another sexual partner increased the odds (aOR = 2.06, 95% CI: 1.33-3.19) of HIV risk.

This study aimed to investigate the association between alcohol use, IPV, and HIV sexual risk behaviors among young people in fishing communities in Uganda. We found that 54% of young people reported three or more HIV risk behaviors and 97% reported at least one HIV risk behavior. Other studies report a high prevalence of HIV risk behaviors in fishing communities [52] [53] [54] [55] . Factors associated with HIV sexual risk behavior included alcohol use, employment status, being in a marital union, and multiple sexual partnerships.

Alcohol use was associated with increased odds of HIV risk behaviors in models 1 and 2. Slight changes in effect sizes for alcohol use were realized when we adjusted for alcohol use and demographic and socioeconomic factors. As earlier stated, alcohol consumption is a risk factor for HIV infection in fishing communities [17] because it impairs judgment, reduces the ability to negotiate for safe sex [10] especially condom use, and promotes multiple sexual partnerships. From our findings, non-or inconsistent condom use was the leading (70%) HIV risk behavior and more than a quarter (28%) of the respondents reported multiple sexual partnerships. Although multiple sexual partnerships were relatively low, they could be underreported due to social desirability bias. Kuteesa and colleagues (2020) noted that alcohol abuse among fishing populations results from work stresses, mobility, geographical remoteness, and limited regulation [17] . Evidence from fishing communities in Koome Islands in Mukono district in Uganda indicates that alcohol misuse among people in the age group 15-24 years was mainly associated with lower education, and depression [17] . Similar evidence has been reported among fishing communities surrounding Lake Victoria in northwestern Tanzania [12] . Contrary to our expectation, we found that IPV was not associated with HIV sexual risk behavior [14, 19] . It is true that sexually or physically abused women are less likely to negotiate for safer sex and are more likely to engage in sexual relations in exchange for money or gifts [21, 56] . From these data, we used the WAST IPV measure. HITS and AAS had borderline statistical significance and multicollinearity. To investigate this relationship further, we conducted bivariate regressions of HIV risk behavior and each of the measures of IPV separately (HITS, WAST, and AAS) and found no significant associations (Results not presented). There is a strong body of evidence that suggests that IPV is associated with HIV risky behaviors [57] [58] [59] . Apparently, alcohol consumption is a stronger predictor of HIV sexual risk than IPV. Alcohol consumption strongly impacts IPV experiences among people within and without fishing communities [28, 60, 61] . As much as IPV was not directly related to HIV sexual risk behavior, there is a possibility of an indirect pathway. This finding is similar that of a study done in India, Haiti, and Mali which did not find an association between IPV and HIV [62] . Also, some study has reported no association between HIV status and IPV rates [63] . From our findings, we suspect under-reporting and social desirability bias regarding IPV. Perhaps, there is a need to investigate this phenomenon further using qualitative inquiries. According to the WHO bulletin, IPV has an indirect effect on HIV by fueling riskier sexual behavior [64] . From our findings, being accused of having an additional sexual partner by a current partner or reporting other sexual partners was associated with HIV sexual risk behavior.

In this study, our findings indicate that working for payment in cash or in-kind in the last 12 months increased the odds of HIV risk. Some young people engage in jobs such as working in bars, and fish trading which may lead to or exacerbate risky sexual behavior even though one earns a wage [57] [58] [59] .

Being married was associated with increased odds (aOR = 2.35, 95% CI: 1.15-4.83) of sexual HIV risk compared to being never married. The literature suggests that HIV risk behavior and infection are higher among married fisher-folk who are highly mobile and stay away from their spouses during work-related mobility seasons [65, 66] .

Finally, being accused by a current partner or having another sexual partner increased the odds (aOR = 2.14, 95% CI: 1.41-3.23) of HIV risk behavior. The Syndemic theory is a good explanation for this phenomenon. One risky sexual behavior has the potential to exacerbate others and therefore, influence health outcomes [67] .

Future studies should examine how patterns of alcohol use differ between males and females and could examine the associations between alcohol abuse and IPV experiences of young people in the fishing communities in Uganda.

Consistent with other fishing communities in East Africa, we found an association between alcohol use and engagement in HIV sexual risk behaviors among young people in eastern and central Ugandan fishing communities. This suggests that interventions to reduce alcohol use among young people may be an important pathway for HIV risk prevention. It may not be realistic to eliminate all forms of alcohol use and abuse from the landing sites. However, it is feasible to formulate regulations and by-laws that regulate alcohol use for young people in the fishing communities in Uganda.

Also, interventions to promote consistent condom use, reduce multiple sexual partnerships, promote faithfulness to one sexual partner, and treat sexually transmitted infections, are critical for young people in the fishing communities in Uganda. Although the Government of Uganda promotes the ABC (abstinence, be faithful, consistent condom use) and male medical circumcision, there is a need to facilitate and implement programs that address these core components of HIV prevention in the fishing communities in Mukono and Namayingo districts.

The strength of this study is that it uses a crosssectional survey to provide evidence about the association between alcohol use, intimate partner violence, and HIV risk behavior among fisherfolk from eastern and central Uganda. Findings from this study should be interpreted considering some limitations. First, the analyses are based on cross-sectional data, which makes it difficult to infer the direction of causality between alcohol, IPV, and HIV risk. Finally, there is a possibility of under-reporting of alcohol abuse, IPV, and HIV risk measures due to stigma, social desirability bias, and trauma.

HIV risk behaviors among young people in fishing communities along Lake Victoria shores are common in Mukono and Namayingo districts. Factors associated with HIV risk among young people included alcohol use, working for payment in cash or kind, being married, and having other sexual partners but not with IPV.

Interventions are needed to address HIV risk behaviors among young people in fishing communities. These should focus on reducing alcohol abuse in these communities. Future research could examine associations between alcohol abuse and the IPV experiences of young people. Interventions to promote consistent condom use, reduce multiple sexual partnerships, and treat sexually transmitted infections are critical for young people in the fishing communities in Uganda. 

The datasets generated and analyzed during the current study are not publicly available due to confidentiality reasons but are available from the corresponding author on reasonable request.

Ethics approval and consent to participate All protocols were carried out in accordance with relevant guidelines and regulations. Ethical approval involved two stages. First, the study protocol was submitted to a local institutional review board (IRB): "The AIDS Support Organization (TASO)" Research and Ethics Committee (TASO REC) and approved on January 5, 2020 (TASOREC/084/19-UG-REC-009). The protocol was subsequently registered with the Uganda National Council of Science and Technology (UNCST) and approved on March 12, 2020 (SS421ES). On March 27, 2020, the UNCST halted the recruitment of study participants in Uganda due to the COVID-19 pandemic. Later (June 4, 2020) the UNCST lifted the halt on recruitment of study participants and recommended formulation of risk management plans (RMP) to be approved by IRBs. We developed an RMP which was approved by TASO REC on July 16, 2020. During the data collection, all research teams and study participants had to wear face masks (provided for by the research team) and use hand sanitizers to reduce the risk of COVID-19 transmission. Written informed consent and verbal assent (for minors below age 18 years) were obtained from all study participants. Participants were informed that participation was voluntary, and they could choose to withdraw at any point as well as not to respond to questions they do not wish to answer. Participants were assured of confidentiality. Participants' names were not recorded alongside their responses. Codes were used instead of participants' names. Survey participants received a compensation of UGX 10,000 (equivalent of USD 2.8).
