RESUMEN

Foreign-born (first-generation) South Asians face a growing diet-related chronic disease burden. Little is known about whether the adult US-born (second-generation) children of South Asian immigrants can provide unique insights as changemakers in their parents' dietary behaviors. This study aims to assess how second-generation South Asians describe and influence the dietary behaviors of their parents. Between October and November 2020, 32 second-generation South Asians [mean age 22.4 (SD 2.9), 53% female] participated in online interviews centered around factors involved in their (and their parents) eating behaviors. Thematic analysis revealed three types of parental dietary drivers (socioecological factors that impact the dietary choices of parents): goal-oriented (i.e., parents' dietary intentionality), capacity-related (e.g., environmental barriers) and sociocultural (cultural familiarity, religion and traditions). Participants described three major mechanisms of influence: recommending new foods, cooking for parents, and bringing new foods home. These influences primarily occurred in the household and often involved participants leveraging their own nutritional knowledge and preferences to expand dietary diversity and healthier behaviors among their parents. Evidence suggests that second-generation South Asians may act as powerful agents of dietary change within their households and can provide novel insights to help address and overcome sociocultural, linguistic, and other structural barriers to better understanding and intervening in the health of the South Asian community.

RESUMEN

BACKGROUND: Asian American (AA) young adults face a looming diet-related non-communicable disease crisis. Interactions with family members are pivotal in the lives of AA young adults and form the basis of family-based interventions; however, little is known on the role of these interactions in shared family food behaviors. Through an analysis of 2021 nationwide survey data of 18-35-year-old AAs, this study examines how the quality of family member interactions associates with changes in shared food purchasing, preparation, and consumption. METHOD: Interaction quality was assessed through 41 emotions experienced while interacting with family, and was categorized as positive (e.g., "I look forward to it"), negative (e.g., "I feel annoyed"), and appreciation-related (e.g., "I feel respected") interactions. Participants were also asked how frequently they ate meals, ate out, grocery shopped, and cooked with their family. RESULTS: Among the 535 AAs surveyed (47.6% East Asian, 21.4% South Asian, 22.6% Southeast Asian), 842 unique family interactions were analyzed; 43.5% of interactions were with mothers, followed by siblings (27.1%), and fathers (18.5%). Participants most frequently ate meals with their family (at least daily for 33.5% of participants), followed by cooking (at least daily for 11.3%). In adjusted analyses, an increase in shared food behaviors was particularly associated with positive interactions, although most strongly with cooking together and least strongly with eating meals together; significant differences between ethnic subgroups were not observed. CONCLUSION: Findings revealed the importance of family interaction quality when leveraging family relationships to develop more tailored, impactful AA young adult dietary interventions.

RESUMEN

Background: Many clinical and population-based research studies pivoted from in-person assessments to phone-based surveys due to the COVID-19 pandemic. The impact of these transitions on survey response remains understudied, especially for people living with HIV. Given that there are gender-specific trends in alcohol and substance use, it is particularly important to capture these data for women.Objective: Identify factors associated with responding to an alcohol and substance use phone survey administered during the COVID-19 pandemic in the Women's Interagency HIV Study, a multicenter US prospective cohort of women living with and without HIV.Methods: We used multivariable logistic regression to assess for associations of pre-pandemic (April-September 2019) sociodemographic factors, HIV status, housing status, depressive symptoms, alcohol use, and substance use with response to an early-pandemic (August-September 2020) phone survey.Results: Of 1,847 women who attended an in-person visit in 2019, 78% responded to a phone survey during the pandemic. The odds of responding were lower for women of Hispanic ethnicity (aOR 0.47 95% CI 0.33-0.66, ref=Black/African American) and those who reported substance use (aOR 0.63 95% CI 0.41-0.98). By contrast, the odds were higher for White women (aOR 1.64 95% CI 1.02-2.70, ref=Black/African American) and those with stable housing (aOR 1.74 95% CI 1.24-2.43).Conclusions: Pivoting from an in-person to phone-administered alcohol and substance use survey may lead to underrepresentation of key subpopulations of women who are often neglected in substance use and HIV research. As remote survey methods become more common, investigators need to ensure that the study population is representative of the target population.

RESUMEN

The dietary behaviors of Asian American (AA) young adults, who face a growing non-communicable disease burden, are impacted by complex socio-ecological forces. Family plays a crucial role in the lifestyle behaviors of AA young adults; however, little is known on the methods, contributors, and impact of familial dietary influence. This study aims to deconstruct the mechanisms of AA young adult familial dietary influence through a multi-perspective qualitative assessment. A five-phase method of dyadic analysis adapted from past research was employed to extract nuanced insights from dyadic interviews with AA young adults and family members, and ground findings in behavioral theory (the Social Cognitive Theory, SCT). 37 interviews were conducted: 18 young adults, comprising 10 different AA ethnic subgroups, and 19 family members (10 parents, 9 siblings). Participants described dietary influences that were both active (facilitating, shaping, and restricting) and passive (e.g., sharing foods or environment, mirroring food behaviors). Influences connected strongly with multiple SCT constructs (e.g., behavioral capacity, reinforcements for active influences, and expectations, observational learning for passive influences). Familial influence contributed to changes in the total amount, variety, and healthfulness of foods consumed. Intra-family dynamics were crucial; family members often leveraged each other's persuasiveness or food skills to collaboratively influence diet. AA family-based interventions should consider incorporating both passive and active forms of dietary influence within a family unit, involve multiple family members, and allow for individualization to the unique dynamics and dietary behaviors within each family unit.

RESUMEN

BACKGROUND: Black older-teenaged women have disproportionately high rates of sexually transmitted infections (STI) and unintended pregnancy (UTP). Internet-based interventions can be delivered to large groups of people in a relatively inexpensive manner. In this randomized trial, we examine the efficacy of an evidence-based STI/UTP prevention intervention adapted for older teens and for Internet delivery. METHODS: Black women aged 18-19 years who were not pregnant/seeking to become pregnant were enrolled (n = 637) and randomized to an 8-session intervention or attention control and were followed up at 6/12 months postintervention. The primary outcome was defined as uptake of reliable contraceptives. Other secondary outcomes were examined, including intention to use condoms, intention to use reliable contraception, and STI or pregnancy rates. RESULTS: Overall, at baseline, reliable contraception was 54.8% and dual protection was 29.4%, and the prevalence of STI was 11.1%. Participants were similar by arm for most factors considered. Participation and follow-up rates were excellent (60.9% and 80.3%). There was no statistically significant difference in uptake of reliable contraception for intervention versus controls at 6 months (1.45 [0.99-2.12]) or 12 months (1.33 [0.92-1.91]). At 6 months, several secondary outcomes were improved/trended toward improvement in intervention compared with control, but this effect waned by 12 months, except for intention to use condoms which remained improved. CONCLUSION AND RELEVANCE: The intervention was efficacious for increasing some self-reported UTP and STI prevention behaviors, which waned over time, and the intervention had minimal impact on STI or pregnancy rates suggesting that this type of online intervention may need additional components.

RESUMEN

Problematic alcohol use is prevalent in Russia and is deleterious for individuals with HIV and Hepatitis C Virus (HCV). Ethyl glucuronide (EtG) and blood alcohol content (BAC) provide objective biomarkers of drinking that can be compared to self-reported alcohol use. This paper describes patterns of alcohol use measured by biomarkers and self-report along with concordance across measures. Participants were Russian women with HIV and HCV co-infection (N = 200; Mean age = 34.9) from two Saint Petersburg comprehensive HIV care centers enrolled in an alcohol reduction intervention clinical trial. Measures were: (a) urine specimen analyzed for EtG; (b) breathalyzer reading of BAC; and (c) self-reported frequency of drinking, typical number of drinks consumed, and number of standard drinks consumed in the past month. At baseline, 64.0% (n = 128) had a positive EtG (> 500 ng/mL) and 76.5% (n = 153) had a positive breathalyzer reading (non-zero reading). There was agreement between EtG and BAC (kappa = 0.66, p < .001; Phi coefficient = 0.69, p < .001); self-reported alcohol measures were positively correlated with positive EtG and BAC (p's < 0.001). There was concordance between EtG and BAC measures, which have differing alcohol detection windows. Most participants endorsed frequent drinking at high quantities, with very few reporting no alcohol consumption in the past month. Concordance between biomarkers and self-reported alcohol use suggests that underreporting of alcohol use was minimal. Results highlight the need for alcohol screening within HIV care. Implications for alcohol assessment within research and clinical contexts are discussed.

RESUMEN

The COVID-19 pandemic has resulted in social isolation and reports of insomnia. However, reports of changes in sleep duration and associated factors are few. To determine the impact of COVID-19 on changes in sleep behavior, data were analyzed from an online survey of adults recruited via social media that included questions asking whether the respondent slept less or more after the onset of the pandemic as well as self-reported sociodemographic and occupational information; beliefs about COVID-19; and responses pertaining to loneliness, anxiety, and depression. There were 5,175 respondents; 53.9% had a change in sleep duration.17.1% slept less and 36.7% slept more. Sleeping more was related to greater education, being single/divorced/separated, unemployed or a student. Being retired, divorced/separated or a homemaker, and living in the Mountain or Central time zones were associated with less sleep. Beliefs that COVID-19 would result in personal adverse consequences was associated with both more and less sleep. However, the strongest associations for both more and less sleep were seen with depression, anxiety, and loneliness. In summary, changes in sleep duration since the start of the COVID-19 pandemic were highly prevalent among social media users and were associated with several sociodemographic factors and beliefs that COVID-19 would have adverse personal impacts. However, the strongest associations occurred with worse mental health suggesting that improvements may occur with better sleep.Supplemental data for this article is available online at https://doi.org/10.1080/08964289.2021.2002800 .

RESUMEN

Background: Asian Americans (AA) young adults face a growing non-communicable disease burden linked with poor dietary behaviors. Family plays a significant role in shaping the diet of AA young adults, although little is known on the specific types of family structures most associated with different dietary behaviors. Aim: This analysis explores the changes in dietary behaviors across different AA young adult family structural characteristics. Methods: Nationwide data of 18-35-year-old self-identified Asians surveyed in the 2015 National Health Interview Survey (NHIS) was analyzed. Family structure was measured through family size, family health, and family members in one's life. The Dietary Screener Questionnaire (DSQ) measured the average intake of 10 food and nutrient groups. Published dietary guidelines were used to calculate the number of dietary recommendations met. Results: 670 AA young adults with dietary data were analyzed (26.1% Asian Indian, 26.1% Chinese, 19.3% Filipino, 28.5% other Asian). Participants had an average family size of 2.3. In weighted analyses, 19% of AA young adults met none of the examined dietary recommendations, and only 14% met 3-4 guidelines. Living with a child was associated meeting more dietary recommendations (adjusted odds ratio [AOR]: 1.22; 95%CI: 1.05, 1.42). The adjusted association between living with an older adult and lower odds of meeting dietary recommendations approached significance (AOR: 0.70; 95%CI: 0.49, 1.00). Conclusions: Findings revealed the important role of children and older adults in influencing the diet of AA young adults. Further mixed-methods research to disentangle mechanisms behind the influence of family structure on diet is warranted.

RESUMEN

African American women experience a high prevalence of alcohol-related consequences, and no studies have explicitly examined the associations among lifetime interpersonal abuse, emotion dysregulation, and alcohol-related outcomes during the critical period of young adulthood within this population. This study used baseline data from a sample of African American young women (N = 560) who use alcohol, aged 18 to 24, enrolled in an HIV prevention intervention trial to examine whether emotion dysregulation mediated the relation between lifetime history of abuse and problematic alcohol use. Further, we sought to examine whether there were potential differential levels of problematic alcohol use based on the number of abuse types experienced. Multiple regression analyses showed that exposure to two or more forms of abuse was associated with problematic alcohol use, ß = .24, p < .001, and heavy alcohol consumption, ß = .23, p < .001, whereas history of a single form was not. Indirect effects of both single and multiple forms of abuse on problematic alcohol use (95% confidence interval [CI] [.16, 1.02]; [.46, 1.64]) and heavy alcohol consumption (95% CI [.02, .26]; [.05, .45]) via emotion dysregulation severity were found. Abuse and emotion dysregulation were associated with frequency of alcohol use and binge drinking, but not typical amount consumed. Hazardous alcohol consumption was prevalent among this sample of African American young women who use alcohol. This study provides preliminary evidence that emotion dysregulation may be an important mechanism buttressing the association between lifetime history of interpersonal abuse and problematic alcohol use among African American young women who use alcohol.

RESUMEN

BACKGROUND: The COVID-19 pandemic has disproportionately impacted economically-disadvantaged populations in the United States (US). Precarious employment conditions may contribute to these disparities by impeding workers in such conditions from adopting COVID-19 mitigation measures to reduce infection risk. This study investigated the relationship between employment and economic conditions and the adoption of COVID-19 protective behaviors among US workers during the initial phase of the COVID-19 pandemic. METHODS: Employing a social media advertisement campaign, an online, self-administered survey was used to collect data from 2,845 working adults in April 2020. Hierarchical generalized linear models were performed to assess the differences in engagement with recommended protective behaviors based on employment and economic conditions, while controlling for knowledge and perceived threat of COVID-19, as would be predicted by the Health Belief Model (HBM). RESULTS: Essential workers had more precarious employment and economic conditions than non-essential workers: 67% had variable income; 30% did not have paid sick leave; 42% had lost income due to COVID-19, and 15% were food insecure. The adoption of protective behaviors was high in the sample: 77% of participants avoided leaving home, and 93% increased hand hygiene. Consistent with the HBM, COVID-19 knowledge scores and perceived threat were positively associated with engaging in all protective behaviors. However, after controlling for these, essential workers were 60% and 70% less likely than non-essential workers, who by the nature of their jobs cannot stay at home, to stay at home and increase hand hygiene, respectively. Similarly, participants who could not afford to quarantine were 50% less likely to avoid leaving home (AOR: 0.5; 95% CI: 0.4, 0.6) than those who could, whereas there were no significant differences concerning hand hygiene. CONCLUSIONS: Our findings are consistent with the accumulating evidence that the employment conditions of essential workers and other low-income earners are precarious, that they have experienced disproportionately higher rates of income loss during the initial phase of the COVID-19 pandemic and face significant barriers to adopting protective measures. Our findings underscore the importance and need of policy responses focusing on expanding social protection and benefits to prevent the further deepening of existing health disparities in the US.

RESUMEN

BACKGROUND: Tackling infodemics with flooding misinformation is key to managing the COVID-19 pandemic. Yet only a few studies have attempted to understand the characteristics of the people who believe in misinformation. METHODS: Data was used from an online survey that was administered in April 2020 to 6518 English-speaking adult participants in the United States. We created binary variables to represent four misinformation categories related to COVID-19: general COVID-19-related, vaccine/anti-vaccine, COVID-19 as an act of bioterrorism, and mode of transmission. Using binary logistic regression and the LASSO regularization, we then identified the important predictors of belief in each type of misinformation. Nested vector bootstrapping approach was used to estimate the standard error of the LASSO coefficients. RESULTS: About 30% of our sample reported believing in at least one type of COVID-19-related misinformation. Belief in one type of misinformation was not strongly associated with belief in other types. We also identified 58 demographic and socioeconomic factors that predicted people's susceptibility to at least one type of COVID-19 misinformation. Different groups, characterized by distinct sets of predictors, were susceptible to different types of misinformation. There were 25 predictors for general COVID-19 misinformation, 42 for COVID-19 vaccine, 36 for COVID-19 as an act of bioterrorism, and 27 for mode of COVID-transmission. CONCLUSION: Our findings confirm the existence of groups with unique characteristics that believe in different types of COVID-19 misinformation. Findings are readily applicable by policymakers to inform careful targeting of misinformation mitigation strategies.

RESUMEN

BACKGROUND: Over the past 10 years, incidence of sexually transmitted infections (STIs) has increased to record numbers in the United States, with the most significant increases observed among adolescents and young adults. The US military, where the majority of active duty personnel are 18-30 years old, has seen similar increases. However, the US military does not yet have a standardized, service-wide program for STI education and prevention. METHODS: The KISS intervention (Knocking out Infections through Safer-sex and Screening) was adapted from an evidence-based intervention endorsed by the US Centers for Disease Control and Prevention and consisted of a one-time, small group session. Content included STI/HIV knowledge and prevention, condom use skills, and interpersonal communication techniques. The intervention was pilot tested for feasibility and acceptability among a population of service members and medical beneficiaries at Joint Base Lewis-McChord in Washington state. RESULTS: A total of 79 participants aged 18-30 years were consented to participate in the pilot study and met entry criteria, 66/79 (82.5%) attended the intervention session, and 46/66 (69.7%) returned at 3 months for the final follow-up assessment. The intervention sessions included 31 male (47.0%) and 35 female (53.0%) participants. Almost all participants felt comfortable discussing sexual issues in the group sessions, reported that they intended to practice safer sex after the intervention, and would also recommend the intervention to friends. Knowledge about STI/HIV prevention significantly increased after the intervention, and intervention effects were maintained at 3 months. About one-fifth of participants tested positive for N. gonorrhea or C. trachomatis infection at enrollment, while none had recurrent STIs at the final visit. Use of both male and female condoms increased after the intervention. CONCLUSIONS: The KISS intervention was feasible to implement in the military setting and was acceptable to the active duty service members and other medical beneficiaries who participated in the pilot project. Further studies are needed to determine if the KISS intervention, or others, effectively decrease STI incidence in active duty personnel and would be appropriate for more widespread implementation. TRIAL REGISTRATION: Retrospectively registered as the pilot phase of clinicaltrials.gov NCT04547413 , "Prospective Cohort Trial to Assess Acceptability and Efficacy of an Adapted STI/HIV Intervention Behavioral Intervention Program in a Population of US Army Personnel and Their Medical Beneficiaries-Execution Phase."

RESUMEN

Family is uniquely influential in the health of young Asian Americans (AAs), yet little is known on the impact of specific shared family activities. This study explores different types and frequencies of AA young adult shared family activities on perceived familial influence on the ability to maintain a healthy lifestyle (diet, physical activity, sleep, social relationships, stress, and risky substances). A nationwide sample of 18-35-year-old AAs was surveyed in March 2021 on a list of 30 shared family activities with mothers, fathers, siblings, or extended family. Overall, 984 unique family relationships reported by 616 young AAs were analyzed. Confirmatory factor analysis synthesized a reliable two-factor (routine, leisure activities) 10-item Shared Activities with Family (SAF) scale. Mothers were most influential (mean 3.25, SD = 1.14), although shared activities among South Asians or with extended family were most associated with changes in perceived influence. Routine shared activities were more strongly associated with perceived influence on sleep, diet, and risky substances, while leisure shared activities were more associated with influence on developing healthy social relationships. Family-based, dyadic interventions for young AAs may incorporate shared activities (both routine and leisure) to promote healthy behaviors, although further research to explore mechanisms and directionality of influence is needed to inform action.

RESUMEN

This analysis of 84 interviews with female Black Church leaders and members from Atlanta, GA, examined how women in Black churches construct definitions of, and identities in relation to, HIV narratives about men on the down low. We analyse these narratives as collective memories, through the theoretical lens of memory and trauma studies, by identifying how women understand themselves as the victims of men on the down low transmitting HIV; describe this as a painful experience; make public claims about this experience; and draw on theological understandings to make these claims. The narratives articulate how Black communal modes of meaning making have been disrupted by the HIV epidemic and assign responsibility for HIV transmission to men on the down low, who are perceived to be engaged in risky sexual behaviour. We discuss these results in relation to HIV education and prevention and suggest health educators can engage Black church leaders by understanding these narratives as forms of countermemory.

RESUMEN

Endowing meta-analytic results with a causal interpretation is challenging when there are differences in the distribution of effect modifiers among the populations underlying the included trials and the target population where the results of the meta-analysis will be applied. Recent work on transportability methods has described identifiability conditions under which the collection of randomized trials in a meta-analysis can be used to draw causal inferences about the target population. When the conditions hold, the methods enable estimation of causal quantities such as the average treatment effect and conditional average treatment effect in target populations that differ from the populations underlying the trial samples. The methods also facilitate comparison of treatments not directly compared in a head-to-head trial and assessment of comparative effectiveness within subgroups of the target population. We briefly describe these methods and present a worked example using individual participant data from three HIV prevention trials among adolescents in mental health care. We describe practical challenges in defining the target population, obtaining individual participant data from included trials and a sample of the target population, and addressing systematic missing data across datasets. When fully realized, methods for causally interpretable meta-analysis can provide decision-makers valid estimates of how treatments will work in target populations of substantive interest as well as in subgroups of these populations.

RESUMEN

There is a growing need to better capture comprehensive, nuanced, and multi-faceted qualitative data while also better engaging with participants in data collection, especially in virtual environments. This study describes the development of a novel 3-step approach to virtual mind-mapping that involves (1) ranked free-listing, (2) respondent-driven mind-mapping, and (3) interviewing to enhance both data collection and analysis of complex health behaviors. The method was employed in 32 virtual interviews as part of a study on eating behaviors among second-generation South Asian Americans. Participants noted the mind-mapping experience to be (1) helpful for visual learners, (2) helpful in elucidating new ideas and to structure thoughts, as well as (3) novel and interesting. They also noted some suggestions that included improving interpretability of visual data and avoiding repetition of certain discussion points. Data collection revealed the adaptability of the method, and the power of mind-maps to guide targeted, comprehensive discussions with participants.

RESUMEN

This study explores a novel, mixed qualitative method to deconstruct the diet of second-generation South Asian Americans (SAAs). Online interviews of 32 second-generation SAAs were conducted usingintegrated free-listing and mind-mapping. Ranked free-lists were aggregated to identify salient drivers, while connections made within mind-maps were analyzed using social network analysis (SNA) methods. Overall, 34 distinct drivers and 247 unique connections were identified. Taste, family, and health had the highest adjusted rankings, while health displayed the strongest network centrality. Interventions aimed at second-generation SAA dietary behaviors may benefit from family-based or multi-level interventions, which consider the complex, unique dietary norms identified.

RESUMEN

BACKGROUND: Objective measurement of alcohol consumption is important for clinical care and research. Adjusting for self-reported alcohol use, we conducted an individual participant data (IPD) meta-analysis to examine factors associated with the sensitivity of phosphatidylethanol (PEth), an alcohol metabolite, among persons self-reporting unhealthy alcohol consumption. METHODS: We identified 21 eligible studies and obtained 4073 observations from 3085 participants with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) positive scores (≥3 for women and ≥4 for men) and PEth measurements. We conducted 1-step IPD meta-analysis using mixed effects models with random intercepts for study site. We examined the associations between demographic (sex, race/ethnicity, and age) and biologic (body mass index-BMI, hemoglobin, HIV status, liver fibrosis, and venous versus finger-prick blood collection) variables with PEth sensitivity (PEth≥8 ng/ml), adjusting for the level of self-reported alcohol use using the AUDIT-C score. RESULTS: One third (31%) of participants were women, 32% were African, 28% African American, 28% White, and 12% other race/ethnicity. PEth sensitivity (i.e., ≥8 ng/ml) was 81.8%. After adjusting for AUDIT-C, we found no associations of sex, age, race/ethnicity, or method of blood collection with PEth sensitivity. In models that additionally included biologic variables, those with higher hemoglobin and indeterminate and advanced liver fibrosis had significantly higher odds of PEth sensitivity; those with higher BMI and those living with HIV had significantly lower odds of PEth sensitivity. African Americans and Africans had higher odds of PEth sensitivity than whites in models that included biologic variables. CONCLUSIONS: Among people reporting unhealthy alcohol use, several biological factors (hemoglobin, BMI, liver fibrosis, and HIV status) were associated with PEth sensitivity. Race/ethnicity was associated with PEth sensitivity in some models but age, sex, and method of blood collection were not. Clinicians should be aware of these factors, and researchers should consider adjusting analyses for these characteristics where possible.

RESUMEN

The COVID-19 pandemic has triggered a public health crisis of unprecedented scale. Increased alcohol use has been extensively documented during other crises, particularly among persons with anxiety and depression. Despite COVID-19's differential impact by age, the association of age, mental health and alcohol use during the pandemic has not been explored. This study aimed to examine whether age modified the association of anxiety and depressive symptoms with alcohol use during the COVID-19 pandemic. Two online surveys were administered to U.S. adult social media users in March and April 2020. Generalized linear models were conducted in 2020 among 5850 respondents (52.9% female; 22.0% aged 18-39 years, 47.0% aged 40-59 years, and 31.0% aged ≥60 years) to examine if age modified the association of anxiety and depression symptomatology and alcohol use. Overall, 29% of respondents reported increased alcohol use. Adjusted odds ratios of reporting increased alcohol use were 1.41 (95% CI = 1.20-1.66) among respondents with anxiety symptoms and 1.64 (95% CI = 1.21-2.23) among those with depressive symptoms compared to those without such symptoms. Whereas respondents aged 18-39 years had the highest probability of reporting increased alcohol use, the probability of older persons (40-59 and ≥60 years) reporting increased drinking was much greater among those with symptoms of anxiety and depression, compared to those without symptoms. These findings warrant age-differentiated public health messaging on the risks of excessive alcohol use and scale-up of substance use services for middle-aged and older adults with symptoms of depression and anxiety.

RESUMEN

Alcohol use remains prevalent among Russian women with HIV infection. Multilevel mixed effects models were used to estimate the association of heavy drinking and HIV outcomes among women (N = 250 at baseline; N = 207 at follow-up), aged 18-35, engaged in HIV care in Saint Petersburg. Alcohol use was assessed at baseline and 3 months by self-report and by the biomarker phosphatidylethanol (PEth). Overall, 35% of women were heavy drinkers, defined as women reporting ≥ 1 past-30-day heavy drinking episode (≥ 4 standard drinks on one occasion) or with PEth blood levels ≥ 80 ng/mL. Women who engaged in heavy drinking had an average 41 CD4 cells/mm3 (95% CI = - 81, - 2; z = - 2.04; P = 0.042) fewer than those who did not. Heavy drinking was associated with higher HIV symptom burden (IRR = 1.20; 95% CI = 1.05, 1.36; z = 2.73; P = 0.006) and suboptimal antiretroviral adherence (OR = 3.04; 95% CI = 1.27, 7.28; χ2 = 2.50; P = 0.013), but not with viral load. Findings support the integration of alcohol treatment interventions as part of routine HIV care in Russia.


RESUMEN: El consumo de alcohol es común en las mujeres rusas con VIH. Utilizamos modelos multinivel de efectos mixtos para estimar la asociación entre el consumo de alcohol excesivo y los resultados adversos de VIH en un grupo de mujeres (N = 250 al inicio del estudio; N = 207 en el seguimiento), de 18 a 35 años de edad, que recibían atención médica para el VIH en San Petersburgo. El consumo de alcohol excesivo, definido como el consumo de ≥ 4 bebidas alcohólicas en una ocasión en base a autoinforme o a niveles de fosfatidiletanol ≥ 80 ng/mL, se evaluó al inicio del estudio y a los 3 meses. Las mujeres que bebían en exceso, el 35% de la muestra, tenían un promedio de 41 células CD4/mm3 (IC del 95% = − 81, − 2; z = − 2,04; P = 0,042) menos que las que no lo hacían. El consumo excesivo de alcohol se asoció con una mayor carga de síntomas de VIH (TIR = 1,20; IC del 95% = 1,05, 1,36; z = 2,73; P = 0,006) y una adherencia al tratamiento antirretroviral subóptima (OR = 3,04; IC del 95% = 1,27, 7,28; χ2 = 2,50; P = 0,013), pero no con carga viral. Los hallazgos respaldan la integración de la atención para el tratamiento del alcoholismo en los servicios de atención rutinaria del VIH en Rusia.
