A venue-based method for sampling hard-to-reach populations

Recruitment and Attrition for Panel Surveys of Hard-to-reach Populations: Some Lessons from a Longitudinal Study on Undocumented Migrants

Conducting research among hard-to-reach populations is a difficult endeavor because some of their characteristics are known to be associated with survey nonresponse and panel attrition. In the case of the Parchemins study, which followed undocumented migrants over their process of regularization and during the first years of regularized life in Geneva, we underscore the difficulties in recruiting and keeping respondents who come from such a hard-to-reach population. Factors hindering their participation include the fear of being denounced as undocumented, missing time due to high workload, health issues, or language problems. Using unique data from the recruitment and the follow-up processes, we demonstrate that investing high resources and time is particularly beneficial to reach such a population and to reduce attrition over successive data collection waves. In addition, we present the strategies adopted to draw a convenient sample from our targeted population, which mainly relies on generating trust.

The women's health needs study among women from countries with high prevalence of female genital mutilation living in the United States: Design, methods, and participant characteristics

BACKGROUND

The Women's Health Needs Study (WHNS) collected information on the health characteristics, needs, and experiences, including female genital mutilation (FGM) experiences, attitudes, and beliefs, of women aged 18 to 49 years who were born, or whose mothers were born, in a country where FGM is prevalent living in the US. The purpose of this paper is to describe the WHNS design, methods, strengths and limitations, as well as select demographic and health-related characteristics of participants.

METHODS

We conducted a cross-sectional survey from November 2020 -June 2021 in four US metropolitan areas, using a hybrid venue-based sampling (VBS) and respondent-driven sampling (RDS) approach to identify women for recruitment.

RESULTS

Of 1,132 participants, 395 were recruited via VBS and 737 RDS. Most were born, or their mothers were born, in either a West African country (Burkina Faso, Guinea, Mali, Mauritania, Sierra Leone, The Gambia) (39.0%) or Ethiopia (30.7%). More than a third were aged 30-39 years (37.5%) with a majority who immigrated at ages ≥13 years (86.6%) and had lived in the United States for ≥5 years (68.9%). Medicaid was the top health insurer (52.5%), followed by private health insurance (30.5%); 17% of participants had no insurance. Nearly half of women reported 1-2 healthcare visits within the past 12 months (47.7%). One in seven did not get needed health care due to cost (14.8%). Over half have ever used contraception (52.1%) to delay or avoid pregnancy and 76.9% had their last pelvic and/or Papanicolaou (pap) exam within the past 3 years. More than half experienced FGM (55.0%). Nearly all women believed that FGM should be stopped (92.0%).

CONCLUSION

The VBS/RDS approach enabled recruitment of a diverse study population. WHNS advances research related to the health characteristics, needs, and experiences of women living in the US from countries where FGM is prevalent.

Combined Motivational Interviewing and Ecological Momentary Intervention to Reduce Hazardous Alcohol Use Among Sexual Minority Cisgender Men and Transgender Individuals: Protocol for a Randomized Controlled Trial

BACKGROUND

Sexual minority cisgender men and transgender (SMMT) individuals, particularly emerging adults (aged 18-34 years), often report hazardous drinking. Given that alcohol use increases the likelihood of HIV risk behaviors, and HIV disproportionately affects SMMT individuals, there is a need to test interventions that reduce hazardous alcohol use and subsequent HIV risk behaviors among this population. Ecological momentary interventions (EMIs), which use mobile phones to deliver risk reduction messages based on current location and behaviors, can help to address triggers that lead to drinking in real time.

OBJECTIVE

This study will test an EMI that uses motivational interviewing (MI), smartphone surveys, mobile breathalyzers, and location tracking to provide real-time messaging that addresses triggers for drinking when SMMT individuals visit locations associated with hazardous alcohol use. In addition, the intervention will deliver harm reduction messaging if individuals report engaging in alcohol use.

METHODS

We will conduct a 3-arm randomized controlled trial (N=405 HIV-negative SMMT individuals; n=135, 33% per arm) comparing the following conditions: (1) Tracking and Reducing Alcohol Consumption (a smartphone-delivered 4-session MI intervention), (2) Tracking and Reducing Alcohol Consumption and Environmental Risk (an EMI combining MI with real-time messaging based on geographic locations that are triggers to drinking), and (3) a smartphone-based alcohol monitoring-only control group. Breathalyzer results and daily self-reports will be used to assess the primary and secondary outcomes of drinking days, drinks per drinking day, binge drinking episodes, and HIV risk behaviors. Additional assessments at baseline, 3 months, 6 months, and 9 months will evaluate exploratory long-term outcomes.

RESULTS

The study is part of a 5-year research project funded in August 2022 by the National Institute on Alcohol Abuse and Alcoholism. The first 1.5 years of the study will be dedicated to planning and development activities, including formative research, app design and testing, and message design and testing. The subsequent 3.5 years will see the study complete participant recruitment, data collection, analyses, report writing, and dissemination. We expect to complete all study data collection in or before January 2027.

CONCLUSIONS

This study will provide novel evidence about the relative efficacy of using a smartphone-delivered MI intervention and real-time messaging to address triggers for hazardous alcohol use and sexual risk behaviors. The EMI approach, which incorporates location-based preventive messaging and behavior surveys, may help to better understand the complexity of daily stressors among SMMT individuals and their impact on hazardous alcohol use and HIV risk behaviors. The tailoring of this intervention toward SMMT individuals helps to address their underrepresentation in existing alcohol use research and will be promising for informing where structural alcohol use prevention and treatment interventions are needed to support SMMT individuals.

Social zeitgeber and sleep loss as risk factors for suicide in American Indian adolescents

American Indians / Alaska Natives (AI/AN) bear a high burden of suicide, the reasons for which are not completely understood, and rates can vary by tribal group and location. This article aims to identify circumstances reported by a community group of American Indian adolescent participants to be associated with their depression and/or suicide. American Indian adolescents (n  =  360) were recruited from contiguous reservations and were assessed with a semi-structured diagnostic interview. Twenty percent of the adolescents reported suicidal thoughts (ideation, plans), an additional 8% reported a history of suicide attempts, and three deaths due to suicide were reported. Suicidal behaviors and major depressive disorder (MDD) co-occurred and were more common among female adolescents. The distressing events that adolescents most often reported were: death in the family, family disruption, peer relationship problems, and school problems. All of these events were significantly associated with suicidal behaviors, however those with suicidal acts were more likely to report death in the family. Those with MDD but no suicidal behaviors were more likely to report disruptions in the family. Disruptions in falling asleep were also associated with suicidal behaviors and having experienced a death in the family. Disruptions in important relationships, particularly through death or divorce, may be interpreted as a loss or disruption in "social zeitgebers" that may in turn disturb biological rhythms, such as sleep, thus potentially increase the risk for MDD and/or suicide. Prevention programs aimed at ameliorating the impact of disruptions in important relationships may potentially reduce suicidal behaviors in AI/AN adolescents.

'I don't know exactly what that means to do check-ups': understanding and experiences of primary care among resettled young adult refugees

Young adult refugees have suboptimal primary care use, including having a regular provider and engaging with a regular source of care for primary and preventive healthcare needs. Our purpose was to understand how young adult refugees (ages 18-29 years) resettled to the United States understand and experience primary care. We conducted 23 semi-structured interviews with young adult refugees and explored their ideas about and experiences of key characteristics of primary care. Emergent themes were synthesized. Young adult refugees reported a lack of an understanding of the idea of primary care. However, they also described the lack of accepted key components of primary care, such as being the first contact and providing continuity, coordination and comprehensiveness. The importance of developing an ability to ask questions, get answers and feel empowered was a facilitator of primary care successes. Young refugees lack access to healthcare that exemplifies quality primary care. Improving understanding of the primary care model and its value as well as increasing access and ease of engagement could improve primary care engagement for young adult refugees.

Predictors of prior HIV testing and acceptance of a community-based HIV test offer among male bar patrons in northern Tanzania

Community-based HIV testing offers an alternative approach to encourage HIV testing among men in sub-Saharan Africa. In this study, we evaluated a community-based HIV testing strategy targeting male bar patrons in northern Tanzania to assess factors predictive of prior HIV testing and factors predictive of accepting a real-time HIV test offer. Participants completed a detailed survey and were offered HIV testing upon survey completion. Poisson regression was used to identify prevalence ratios for the association between potential predictors and prior HIV testing or real-time testing uptake. Of 359 participants analyzed, the median age was 41 (range 19-82) years, 257 (71.6%) reported a previous HIV test, and 321 (89.4%) accepted the real-time testing offer. Factors associated with previous testing for HIV (adjusted prevalence ratio [aPR], 95% CI) were wealth scores in the upper-middle quartile (1.25, 1.03-1.52) or upper quartile (1.35, 1.12-1.62) and HIV knowledge (1.04, 1.01-1.07). Factors that predicted real-time testing uptake were lower scores on the Gender-Equitable Men scale (0.99, 0.98-0.99), never testing for HIV (1.16, 1.03-1.31), and testing for HIV > 12 months prior (1.18, 1.06-1.31). We show that individual-level factors that influence the testing-seeking behaviors of men are not likely to impact their acceptance of an HIV offer.

Prevalence of SARS-CoV-2 Infection among Children and Adults in 15 US Communities, 2021

During January-August 2021, the Community Prevalence of SARS-CoV-2 Study used time/location sampling to recruit a cross-sectional, population-based cohort to estimate SARS-CoV-2 seroprevalence and nasal swab sample PCR positivity across 15 US communities. Survey-weighted estimates of SARS-CoV-2 infection and vaccine willingness among participants at each site were compared within demographic groups by using linear regression models with inverse variance weighting. Among 22,284 persons >2 months of age and older, median prevalence of infection (prior, active, or both) was 12.9% across sites and similar across age groups. Within each site, average prevalence of infection was 3 percentage points higher for Black than White persons and average vaccine willingness was 10 percentage points lower for Black than White persons and 7 percentage points lower for Black persons than for persons in other racial groups. The higher prevalence of SARS-CoV-2 infection among groups with lower vaccine willingness highlights the disparate effect of COVID-19 and its complications.

Comorbidity of anxiety/affective, conduct/antisocial, attention deficit, and alcohol use disorders with suicidal behaviors in an American Indian community sample of adults and adolescents

AIMS

To study the associations of anxiety/affective disorders, conduct/antisocial disorders (ASPD/CD), attention deficit disorders (ADHD), and alcohol use disorders (AUD) with suicidal behaviors in an American Indian (AI) community sample of adolescents and adults.

METHODS

Participants were AI (360 adolescents, 925 adults) recruited from reservations who were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA).

RESULTS

Among AI adults (mean age = 33 years), 17% percent reported lifetime experiences of suicidal thoughts (ideation and/or plans) and 14% reported suicidal acts (including either a suicide attempt history or verified death by suicide; n = 19 deaths). Among AI adolescents (mean age = 15 years), 20% experienced suicidal thoughts and 9% experienced suicidal acts (including 3 deaths). In logistic regression analyses, suicidal thoughts were significantly associated with lifetime diagnoses of affective disorder, CD and ADHD in adolescents, and with anxiety disorder, affective disorder, and ASPD/CD in adults. Suicidal acts were associated with affective disorder, ADHD, and alcohol drinking in adolescents and with anxiety disorder, ASPD/CD and AUD in adults. The number of comorbid disorders greatly increased the risk of both suicidal thoughts and acts among both adolescents and adults.

CONCLUSIONS

In addition to affective disorders, both ADHD and CD in adolescents, and ASPD in adults, demonstrated an association with suicidal thoughts. Alcohol use by adolescents and AUD among adults also were associated with suicidal attempts in this AI sample. These findings suggest need for additional research and potential integration of alcohol in screening and intervention programs focused on the prevention of suicide among AI.

Life-time HIV testing among people who inject drugs in Iran: results from the National Rapid Assessment and Response survey

Background

HIV testing is recommended for people who inject drugs (PWID). The aim of this study was to determine the prevalence of lifetime HIV testing among PWID and to better understand the predictors for HIV testing in a convenience sample across Iran.

Materials and methods

This study is a secondary analysis of Iran's National Rapid Assessment and Response survey conducted between October 2016 and March 2017. Analysis includes the 999 people who reported injecting drugs across the capital cities of 21 provinces. Data were collected by using the venue-based application of the Time Location Sampling (TLS) frame. Chi-square tests were used to examine the difference between HIV testing across different quantitative variables. Logistic regression was used to determine the predictors of life-time HIV testing. Analysis was performed using STATA V.12 software with a significance level of 95%.

Results

Most participants were male (n = 902, 93.50%), and over half (n = 555, 59.17%) were older than 35 years old. About one-third, (n = 326, 38%) of people interviewed were single and another one-third (n = 251, 29%) reported being divorced. Over two-thirds of participants (n = 678, 69.78%) in this study reported lifetime HIV testing. The results from a multiple variable logistic regression showed people with a university education were more likely to have been previously tested for HIV than illiterate people (OR = 18.87, 95%CI 2.85-124.6, value of p = 0.002). Those individuals who reported ever receiving methadone treatment were 2.8 times more likely to have been tested for HIV than individuals without methadone treatment experience (OR = 2.89, 95%CI 1.53-5.42, value of p < 0.001). Needle syringe sharing in last month, was negatively associated with life-time HIV testing (OR = 0.29, 95%CI 0.17-0.48, value of p < 0.001).

Conclusion

Despite Iran's wide availability and access to counseling services for HIV testing in key populations, the proportion of PWID being tested for HIV could be improved. Developing effective strategies to increase people's understanding and awareness of the importance of and need for HIV prevention and familiarity with HIV testing sites is an essential step in increasing HIV testing for this population. Studies on more recent HIV testing are required to better assess and understand the frequency of HIV testing among PWID in Iran.

Poor self-reported sleep quality associated with suicide risk in a community sample of American Indian adults

Study Objectives

Although American Indian/Alaska Native (AI/AN) have high suicide rates few studies have systematically investigated sleep quality and its association with suicidal behaviors in AI/AN. This study is a cross-sectional investigation of self-reported sleep quality and suicidal behaviors in an adult AI population.

Methods

A semi-structured interview was used to collect data on suicidal ideation, suicidal plans, and suicidal attempts and the Pittsburgh Sleep Quality Index (PSQI) was collected to assess sleep quality in American Indian adults.

Results

In this sample (n = 477), 91 (19%) of the participants endorsed suicidal ideation (thoughts and plans), and 66 (14%) reported suicidal attempts, including four who subsequently died by suicide. More women reported suicidal thoughts or acts than men. Those endorsing suicidal thoughts slept fewer hours during the night, reported more nocturnal awakenings, and showed poorer subjective sleep quality according to PSQI total scores compared to those with no suicidal thoughts or acts. Participants with suicidal acts (n = 66) reported more bad dreams and higher PSQI total scores compared to those with no suicidal thoughts or acts. When those with any suicidal thoughts or acts (n = 157, 33%) were compared to those without, they were more likely to endorse nocturnal awakenings and bad dreams and demonstrated significantly higher PSQI total scores.

Conclusions

Although additional research is needed to evaluate sleep disturbances as a proximal, causal risk factor for suicidal behaviors in AI, findings highlight need for further study of sleep as a warning sign and intervention tool for suicide prevention among American Indian adults.

Population Size Estimation of Men Who Have Sex With Men in Rwanda: Three-Source Capture-Recapture Method

BACKGROUND

Globally, men who have sex with men (MSM) continue to bear a disproportionately high burden of HIV infection. Rwanda experiences a mixed HIV epidemic, which is generalized in the adult population, with aspects of a concentrated epidemic among certain key populations at higher risk of HIV infection, including MSM. Limited data exist to estimate the population size of MSM at a national scale; hence, an important piece is missing in determining the denominators to use in estimates for policy makers, program managers, and planners to effectively monitor HIV epidemic control.

OBJECTIVE

The aims of this study were to provide the first national population size estimate (PSE) and geographic distribution of MSM in Rwanda.

METHODS

Between October and December 2021, a three-source capture-recapture method was used to estimate the MSM population size in Rwanda. Unique objects were distributed to MSM through their networks (first capture), who were then tagged according to MSM-friendly service provision (second capture), and a respondent-driven sampling survey was used as the third capture. Capture histories were aggregated in a 2k-1 contingency table, where k indicates the number of capture occasions and "1" and "0" indicate captured and not captured, respectively. Statistical analysis was performed in R (version 4.0.5) and the Bayesian nonparametric latent-class capture-recapture package was used to produce the final PSE with 95% credibility sets (CS).

RESULTS

We sampled 2465, 1314, and 2211 MSM in capture one, two, and three, respectively. There were 721 recaptures between captures one and two, 415 recaptures between captures two and three, and 422 recaptures between captures one and three. There were 210 MSM captured in all three captures. The total estimated population size of MSM above 18 years old in Rwanda was 18,100 (95% CS 11,300-29,700), corresponding to 0.70% (95% CI 0.4%-1.1%) of total adult males. Most MSM reside in the city of Kigali (7842, 95% CS 4587-13,153), followed by the Western province (2469, 95% CS 1994-3518), Northern province (2375, 95% CS 842-4239), Eastern province (2287, 95% CS 1927-3014), and Southern province (2109, 95% CS 1681-3418).

CONCLUSIONS

Our study provides, for the first time, a PSE of MSM aged 18 years or older in Rwanda. MSM are concentrated in the city of Kigali and are almost evenly distributed across the other 4 provinces. The national proportion estimate bounds of MSM out of the total adult males includes the World Health Organization's minimum recommended proportion (at least 1.0%) based on 2012 census population projections for 2021. These results will inform denominators to be used for estimating service coverage and fill existing information gaps to enable policy makers and planners to monitor the HIV epidemic among MSM nationally. There is an opportunity for conducting small-area MSM PSEs for subnational-level HIV treatment and prevention interventions.

Geographically skewed recruitment and COVID-19 seroprevalence estimates: a cross-sectional serosurveillance study and mathematical modelling analysis

OBJECTIVES

Convenience sampling is an imperfect but important tool for seroprevalence studies. For COVID-19, local geographic variation in cases or vaccination can confound studies that rely on the geographically skewed recruitment inherent to convenience sampling. The objectives of this study were: (1) quantifying how geographically skewed recruitment influences SARS-CoV-2 seroprevalence estimates obtained via convenience sampling and (2) developing new methods that employ Global Positioning System (GPS)-derived foot traffic data to measure and minimise bias and uncertainty due to geographically skewed recruitment.

DESIGN

We used data from a local convenience-sampled seroprevalence study to map the geographic distribution of study participants' reported home locations and compared this to the geographic distribution of reported COVID-19 cases across the study catchment area. Using a numerical simulation, we quantified bias and uncertainty in SARS-CoV-2 seroprevalence estimates obtained using different geographically skewed recruitment scenarios. We employed GPS-derived foot traffic data to estimate the geographic distribution of participants for different recruitment locations and used this data to identify recruitment locations that minimise bias and uncertainty in resulting seroprevalence estimates.

RESULTS

The geographic distribution of participants in convenience-sampled seroprevalence surveys can be strongly skewed towards individuals living near the study recruitment location. Uncertainty in seroprevalence estimates increased when neighbourhoods with higher disease burden or larger populations were undersampled. Failure to account for undersampling or oversampling across neighbourhoods also resulted in biased seroprevalence estimates. GPS-derived foot traffic data correlated with the geographic distribution of serosurveillance study participants.

CONCLUSIONS

Local geographic variation in seropositivity is an important concern in SARS-CoV-2 serosurveillance studies that rely on geographically skewed recruitment strategies. Using GPS-derived foot traffic data to select recruitment sites and recording participants' home locations can improve study design and interpretation.

Trauma, historical trauma, PTSD and suicide in an American Indian community sample

AIMS

To study the associations between perceived historical trauma, current traumatic events, diagnoses of post-traumatic stress disorder (PTSD), and suicidal behaviors in an American Indian community sample.

METHODS

Participants were American Indians recruited from reservations who were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), as well as the Historical Loss Scale, Historical Loss Associated Symptoms Scale, and Stressful Life Events Scale.

RESULTS

In data from 447 American Indian adults (mean age = 33 years), twenty percent reported lifetime experiences of suicidal thoughts (ideation and/or plans) and 14% reported suicidal acts, (including either a suicide attempt history or verified death by suicide (n = 4)). Diagnosis of PTSD and experience of assaultive trauma were each significantly associated with suicidal thoughts and acts, although assaultive trauma did not remain significant in models adjusting for gender and PTSD. High endorsement of symptoms associated with historical trauma was significantly associated with suicidal acts, and this remained significant when adjusting for gender and PTSD.

CONCLUSIONS

PTSD and historical trauma have an association with suicide and suicidal attempts in this American Indian community. Although further research is needed to evaluate the causal nature of these relations, these findings suggest treatment and prevention programs for American Indian suicide may benefit from addressing issues related to feelings of historical losses, PTSD, and their associated symptomatology.

Racial And Ethnic Disparities In Pandemic-Era Unemployment Insurance Access: Implications For Health And Well-Being

Research demonstrates that receiving unemployment insurance decreases mental health problems. But researchers have also found racial and ethnic disparities in unemployment insurance receipt resulting from differences in work history and location. We examined a population disproportionately affected by job loss and unemployment insurance exclusions, using a survey of service workers from a single city who were parents of young children and who overwhelmingly had eligible work histories. During the COVID-19 pandemic, workers not identifying as White non-Hispanic in our sample were more likely to get laid off than White workers. Among those who were laid off, these workers and White workers experienced similar increases in material and mental health difficulties and similar gains when they received unemployment insurance. However, these workers were less likely than White workers to receive unemployment insurance at all. These results indicate that unemployment insurance has unrealized potential to reduce material and health disparities. Policies should be implemented to make this coverage more effective and equitable through increased access.

Who is in the sample? An analysis of real and surrogate users as participants in user study research in the information technology fields

Background

Constructing a sample of real users as participants in user studies is considered by most researchers to be vital for the validity, usefulness, and applicability of research findings. However, how often user studies reported in information technology academic literature sample real users or surrogate users is unknown. Therefore, it is uncertain whether or not the use of surrogate users in place of real users is a widespread problem within user study practice.

Objective

To determine how often user studies reported in peer-reviewed information technology literature sample real users or surrogate users as participants.

Method

We analyzed 725 user studies reported in 628 peer-reviewed articles published from 2013 through 2021 in 233 unique conference and journal outlets, retrieved from the ACM Digital Library, IEEE Xplore, and Web of Science archives. To study the sample selection choices, we categorized each study as generic (i.e., users are from the general population) or targeted (i.e., users are from a specific subpopulation), and the sampled study participants as real users (i.e., from the study population) or surrogate users (i.e., other than real users).

Results

Our analysis of all 725 user studies shows that roughly two-thirds (75.4%) sampled real users. However, of the targeted studies, only around half (58.4%) sampled real users. Of the targeted studies sampling surrogate users, the majority (69.7%) used students, around one-in-four (23.6%) sampled through crowdsourcing, and the remaining 6.7% of studies used researchers or did not specify who the participants were.

Conclusions

Key findings are as follows: (a) the state of sampling real users in information technology research has substantial room for improvement for targeted studies; (b) researchers often do not explicitly characterize their study participants in adequate detail, which is probably the most disconcerting finding; and (c) suggestions are provided for recruiting real users, which may be challenging for researchers.

Implications

The results imply a need for standard guidelines for reporting the types of users sampled for a user study. We provide a template for reporting user study sampling with examples.

Molecular epidemiology and characterization of Babesia bovis in cattle of Khyber Pakhtunkhwa province, Pakistan

Babesiosis is a tick-borne disease found globally but most prominent in tropical and subtropical regions. It is responsible for huge mortality and morbidity, especially in developing countries like Pakistan. The current study was designed to determine the molecular epidemiology and characterization of Babesia bovis (B. bovis) infection in cattle populations of districts Mardan, Kohat and Swat of Khyber Pakhtunkhwa (KP) province of Pakistan. A total of 434 tick-infested animals were sampled. Blood samples were collected, processed and then examined initially by microscopy for the presence of Babesia and were later confirmed through PCR by targeting cytochrome b gene, and the PCR products were sequenced. Phylogenetic analysis of sequenced isolates of the current study showed close sequence similarity with the reported strain of China. A non-significant association (p > 0.05) was observed between the prevalence of infections and risk factors. The overall prevalence of infection in all three districts was 10.11%. In district Swat (12.61%), the prevalence was recorded as the highest for B. bovis infection followed by district Mardan (10.60%) and district Kohat (06.90%). The Friesian breed of cattle, females and adult animals were highly susceptible to B. bovis infection. The prevalence of infection was recorded highest during the summer season and lowest during the winter season. This study concludes that B. bovis infection is prevalent in three studied districts of KP province and the sequenced isolates of the current study showed close sequence similarity with the reported strain of China.

Effect of daily school and care disruptions during the COVID-19 pandemic on child behavior problems

The COVID-19 pandemic profoundly affected American families and children, including through the closure or change in the nature of their care and school settings. As the pandemic has persisted, many children remain in remote schooling and those attending in-person childcare or school have contended with unpredictable closures. This study investigated the frequency and consequences of disruptions to children's childcare and school arrangements during Fall 2020. The sample is parents who were hourly service-sector workers prior to the pandemic, had a young child between the ages of 3 and 8, and were at least partially responsible for their children's school and/or care in Fall 2020 (N = 676); half of the sample were non-Hispanic Black, 22% were Hispanic, and 18% are non-Hispanic White. Parents were asked to complete 30 days of daily surveys about whether their care and school arrangements went smoothly and as predicted that day, about their mood, parenting behaviors, and children's behavior. Results showed that daily disruptions to care and school were common, with families reporting a disruption on 24% of days. Families with children in exclusively remote schooling experienced more frequent disruption than families with children in in-person care or school. For all families, care or school disruptions were related to worse child behavior, more negative parental mood, and increased likelihood of losing temper and punishment. Within-family mediation suggests that parents' difficulties supporting children's learning, and to a lesser degree their mood and parenting behaviors, partially mediate effects of disruptions on child behavior.

Housing Instability, Structural Vulnerability, and Non-Fatal Opioid Overdoses Among People Who Use Heroin in Washington Heights, New York City

Nationally, opioid overdose remains strikingly persistent among people experiencing homelessness and housing instability. Limited information is available about the characteristics of this phenomenon in economically disadvantaged communities of color. This study sought to evaluate the association between key contextual factors and experiencing a non-fatal opioid overdose among people who use heroin in Washington Heights, New York City. We conducted a cross-sectional survey (N = 101) among participants seeking harm reduction services who reported heroin use in the last three months. Binary logistic regression models examined the association between key social and structural factors and the likelihood of ever experiencing a non-fatal opioid overdose and recently experiencing a non-fatal opioid overdose. The majority of the sample reported housing instability and lived in poverty; almost 42% were homeless. After adjustment, participants who injected heroin were more likely to have ever experienced a non-fatal opioid overdose. Also, younger participants who reported hunger in the last six months were more likely to have experienced a non-fatal opioid overdose in the last three months. Findings suggest the role of structural vulnerability in shaping overdose risk among the participants. Overdose prevention strategies should consider factors of the social and economic environment to mitigate barriers to accessing health and social services within the context of the current opioid crisis.

A Review of Prevalence Estimation Methods for Human Trafficking Populations

Human trafficking has long-lasting implications for the well-being of trafficked people, families, and affected communities. Prevention and intervention efforts, however, have been stymied by a lack of information on the scale and scope of the problem. Because trafficked people are mostly hidden from view, traditional methods of establishing prevalence can be prohibitively expensive in the recruitment, participation, and retention of survey participants. Also, trafficked people are not randomly distributed in the general population. Researchers have therefore begun to apply methods previously used in public health research and other fields on hard-to-reach populations to measure the prevalence of human trafficking. In this topical review, we examine how these prevalence methods used for hard-to-reach populations can be used to measure the prevalence of human trafficking. These methods include network-based approaches, such as respondent-driven sampling and the network scale-up method, and venue-based methods. Respondent-driven sampling is useful, for example, when little information about the trafficked population has been produced and when an adequate sampling frame does not exist. The network scale-up method is unique in that it does not target the hidden population directly. The implications of our work internationally include the need for documenting and validating the various prevalence estimation methods in the United States in a more robust way than was done in existing efforts. In providing this roadmap for estimating the prevalence of human trafficking, our overarching goal is to promote the equitable treatment and overall well-being of the socially disadvantaged populations who disproportionately experience human trafficking.

Factors associated with poor access to HIV and sexual and reproductive health services in Nigeria for women and girls living with HIV during the COVID-19 pandemic

Aim: To determine the proportion of women and girls living with HIV (WGLHIV) who had poor access to HIV, tuberculosis and sexual and reproductive health (SRH) services in Nigeria during the COVID-19 pandemic and associated factors.Methods: This was a cross-sectional study that recruited WGLHIV with six categories of vulnerability (sex work, transactional sex, injecting or using illegal drugs, people on the move, transgender women and people with a disability) through an online survey conducted in ten Nigerian states between june and October 2021. The associations between the limited access to HIV, tuberculosis and SRH services due to COVID-19, the categories of vulnerability and the financial and non-financial barriers to these services were determined using multivariable logistics regression analysis.Results: Over 6 in 10, almost 2 in 10, and almost 4 in 10 WGLHIV had limited access to HIV, tuberculosis and SRH services respectively during the COVID-19 pandemic. Transgender women had 3.59 (95% CI 2.19-5.91) higher odds, women who engaged in sex work had 4.51 (95% CI 2.28-8.42) higher odds, and women who inject or use illegal drugs had 2.39 (95% CI 1.47-32.90) higher odds of facing limited access to sexual and reproductive health services when it was needed. In addition, the direct consequences of the COVID-19 crisis, such as the closure of HIV services and SRH service points, exacerbated pre-existing barriers significantly. Having no money, having to pay additional unofficial fees and the lack of security on the road to the health facility were the barriers with the greatest impact on access to health services.Conclusions: The COVID-19 pandemic had a negative impact on the access of WGLHIV to essential health services. This impact was disproportionately higher for marginalised groups. WGLHIV need non-discriminatory and affordable access to essential health services during the pandemic.

Santos Remedios: How Mexican Immigrants Use Authoritative Healing Knowledge to Survive Migration

Mexicans living in the United States frequently rely upon popular healing to address a broad spectrum of physical, psychological, and spiritual ailments. They practice Mesoamerican healing ways including using herbal remedies, employing nutritional health promotion and illness remediation, over the counter pharmaceuticals, prayer and religion, and visiting expert healers. In this article, we utilize Brigitte Jordan's theory of "authoritative knowledge," to show how Mexican immigrants' ancestral and ecological-based healing knowledge travels with them through migration. Based on original ethnographic research in the Southwest borderlands, we expand an understanding of the factors that support the continuity of authoritative knowledge spatially and temporally. Mexicans' healing knowledge persisted north of the border because it (1) incorporated a wide array of healing techniques and materials that remained accessible post-migration, (2) enabled immigrants to heal according to Mesoamerican worldviews that privileged natural modalities and a holistic approach to body, mind, and spirit, and (3) remained relevant by allowing immigrants to remedy daily health stressors inherent to Mexican migration, including the border crossing, detention and deportation, and daily fear provoked by undocumented status. While lay practices have often been interpreted as problematic by medical professionals, we conclude that Mexicans' authoritative healing knowledge serves as a survival mechanism during the challenging circumstances of binational migration.

Estimating willingness to pay for public health insurance while accounting for protest responses: A further step towards universal health coverage in Tunisia?

Introduction

Developing countries face major challenges in implementing universal health coverage (UHC): a widespread informal sector, general discontent with rising economic insecurity and inequality and the rollback of state and public welfare. Under such conditions, estimating the demand for a health insurance scheme (HIS) on voluntary basis can be of interest to accelerate the progress of UHC‐oriented reforms. However, a major challenge that needs to be addressed in such context is related to protest attitudes that may reflect, inter alia, a null valuation of the expected utility or unexpressed demand.

Methods

We propose to tackle this by applying a contingent valuation survey to a non‐healthcare‐covered Tunisian sample vis‐à‐vis joining and paying for a formal HIS. Our design pays particular attention to identifying the nature of the willingness‐to‐pay (WTP) values obtained, distinguishing genuine null values from protest values. To correct for potential selection issues arising from protest answers, we estimate an ordered‐Probit‐selection model and compare it with the standard Tobit and Heckman sample selection models.

Results

Our results support the presence of self‐selection and, by predicting protesters' WTP, allow the “true” sample mean WTP to be computed. This appears to be about 14% higher than the elicited mean WTP.

Conclusion

The WTP of the poorest non‐covered respondents represents about one and a half times the current contributions of the poorest formal sector enrolees, suggesting that voluntary participation in the formal HIS is feasible.

We study how protest positions may impact affiliation to formal health insurance

We apply a contingent valuation survey to a non‐healthcare‐covered population

We account and correct for selection issues with appropriate econometric models

Accounting for protest positions is found to impact the implementation of UHC

Immigrant generational status and the uptake of HIV screening services among heterosexual men of African descent in Canada: Evidence from the weSpeak study

Objective

Canada became a preferred destination for many non-European and non-American migrants since the introduction of favorable immigration policies in the late 1960 s. Blackimmigrants from the African and Caribbean regions however are a known vulnerable population to HIV infection in Canada. Even though first-generation immigrants might differ from subsequent generations in terms of culture and beliefs which are important for health outcomes and behaviors, research examining disparities in their use of preventative healthcare is limited. This study aimed to examine generational disparities in the uptake of HIV screening services among a sample of heterosexual Black men in Ontario, Canada.

Methods

We used data from a cross-sectional survey sample (n = 829) that was collected from heterosexual Black men in four Ontarian cities (Toronto, Ottawa, London and Windsor) between March 2018 and February 2019. We used the negative log-log link function of the binomial family to examine the independent relationship between immigration status and the uptake of HIV testing and the cumulative effect of other predictor variables on HIV testing in nested models.

Results

Findings from multivariate analysis show second-generation immigrants were significantly less likely to test for HIV compared with their first-generation immigrant counterparts. After controlling for theoretically relevant variables, the second-generation immigrants were 53% less likely to test for HIV. We further observed that participants with good knowledge of HIV transmission (OR=1.05; p > 0.05) and those who were older were more likely to test for HIV. Those with masculine tendencies (OR=0.98; p > 0.05) and those who reported not having sexual partner were less likely to test (OR=0.57; p > 0.01). Religion emerged as a significant predictor of HIV testing as Christians (OR=1.62; p > 0.05) and other believers (OR=1.59; p > 0.05) were more likely to test for HIV when compared to their Muslim counterparts.

Conclusion

HIV prevention policies may need not only prioritize first-generation immigrants, but the wellbeing of their descendants as well. This could be achieved by implementing programs that will enhance second-generation immigrants’ use of HIV screening services. Additionally, HIV educational programs would be of relevance and especially so as respondents with good knowledge of HIV transmission consistently demonstrated higher likelihood of testing for their HIV status.

Prevalence and associated risk factors of HIV infections in a representative transgender and non-binary population in Flanders and Brussels (Belgium): Protocol for a community-based, cross-sectional study using time-location sampling

Introduction

HIV prevalence and sexual risk have been estimated very high for transgender people. However, the limited sampling and data collection methods used in current research on transgender people potentially led to overrepresentation and generalisation of people at risk for HIV. Current HIV prevalence estimates in transgender populations are generalised from studies mainly focusing on transgender women engaging in sex work. Moreover, studies focusing on non-binary people, who identify with a broad range of identities beyond the traditional male and female gender identities, are scarce.

Objectives

To estimate the HIV prevalence rate in the Flemish and Brussels (Belgium) transgender population, including transgender women, transgender men and non-binary people, and to identify the associated risk factors.

Methods

In this community-based cross-sectional study, self-identified transgender and non-binary (TGNB) people will be recruited through a two-stage time-location sampling approach. First, community settings in which TGNB people gather will be mapped to develop an accurate sampling frame. Secondly, a multistage sampling design is applied involving a stratification based on setting type (healthcare facilities vs outreach events), a selection of clusters by systematic sampling and a simple random selection of TGNB people within each cluster. Participants will complete an electronic self-reported survey to measure sociological, sexual and drug-using behaviors (risk factors) and oral fluid aliquots will be collected and tested for HIV antibodies. Logistic regression models will be used to evaluate risk factors independently associated with HIV infection. The presented study is registered at ClinicalTrials.gov (NCT04930614).

Discussion

This study will be the first to investigate the HIV prevalence rates and associated risk behaviors in an accurate representation of the TGNB population in a Western European country. The findings will globally serve as a knowledge base for identifying subgroups at risk for becoming infected with HIV within TGNB people and to set up targeted prevention programs.

What is the prevalence of and trend in opioid use disorder in the United States from 2010 to 2019? Using multiplier approaches to estimate prevalence for an unknown population size

Opioid-related overdose deaths have increased since 2010 in the U.S., but information on trends in opioid use disorder (OUD) prevalence is limited due to unreliable data. Multiplier methods are a classical epidemiological technique to estimate prevalence when direct estimation is infeasible or unreliable. We used two different multiplier approaches to estimate OUD prevalence from 2010 to 2019. First, we estimated OUD in National Survey on Drug Use and Health (NSDUH), and based on existing capture-recapture studies, multiplied prevalence by 4.5x. Second, we estimated the probability of drug poisoning death among people with OUD (Meta-analysis indicates 0.52/100,000), and divided the number of drug poisoning deaths in the US by this probability. Estimates were weighted to account for increase in drug-related mortality in recent years due to fentanyl. Estimated OUD prevalence was lowest when estimated in NSDUH with no multiplier, and highest when estimated from vital statistics data without adjustment. Consistent findings emerged with two methods: NSDUH data with multiplier correction, and vital statistics data with multiplier and adjustment. From these two methods, OUD prevalence increased from 2010 to 2014; then stabilized and slightly declined annually (survey data with multiplier, highest prevalence of 4.0% in 2015; death data with a multiplier and correction, highest prevalence of 2.35% in 2016). The number of US adolescent and adult individuals with OUD in 2019 was estimated between 6.7-7.6 million. When multipliers and corrections are used, OUD may have stabilized or slightly declined after 2015. Nevertheless, it remains highly prevalent, affecting 6-7 million US adolescents and adults.

Respondent-Driven Sampling: a Sampling Method for Hard-to-Reach Populations and Beyond

Purpose of Review

We provided an overview of sampling methods for hard-to-reach populations and guidance on implementing one of the most popular approaches: respondent-driven sampling (RDS).

Recent Findings

Limitations related to generating a sampling frame for marginalized populations can make them “hard-to-reach” when conducting population health research. Data analyzed from non-probability-based or convenience samples may produce estimates that are biased or not generalizable to the target population. In RDS and time-location sampling (TLS), factors that influence inclusion can be estimated and accounted for in an effort to generate representative samples. RDS is particularly equipped to reach the most hidden members of hard-to-reach populations.

Summary

TLS, RDS, or a combination can provide a rigorous method to identify and recruit samples from hard-to-reach populations and more generalizable estimates of population characteristics. Researchers interested in sampling hard-to-reach populations should expand their toolkits to include these methods.

Sexually Transmitted Infections and Associated Risk Factors Among Male Clients of Sex Workers: A Cross-Sectional Pilot Project in Antwerp, Belgium

INTRODUCTION

Prevalence of sexually transmitted infections (STIs) is increasing in Belgium in recent years. Clients of sex workers form a key population for acquisition of STIs, due to their sexual relations, with or without a condom, with sex workers. STI testing uptake is low among clients of sex workers, and prevalence of STIs remains to be investigated in Belgium. Therefore, we offered STI-testing to clients of sex workers during outreach sessions in Antwerp.

METHODS

Time location sampling (TLS) was used to improve representativeness of the sample during ten test sessions in the red light district, Antwerp in May and September 2019 by using a passive approach. Individuals that were interested to get tested for STIs could enter the study. Participants completed an online survey and samples for STI testing were collected. Testing included HIV, syphilis, Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (Ng). Test results were communicated via a cell phone message (for negative test results) or by phone (for positive test results).

RESULTS

In total, 154 male clients of sex workers with a median age of 38 participated. A total of eight Ct and one Ng infections were detected. TLS analysis revealed a Ct/Ng prevalence of 8.2%. No new HIV nor syphilis infections were detected. Using univariate analysis, testing positive for STI was associated with younger age and anorectal sex with a sex worker. Using multivariate analysis, an STI-positive test result was associated with being younger, having non-Belgian nationality, and being in a relationship.

CONCLUSION

Our study found a substantial prevalence of Ct/Ng which highlights the need for sensitization and facilitation of STI testing among clients of sex workers. It is difficult to compare results due to the lack of reference material. Moreover, our relatively small convenience sample limits generalizability of results. However, phone counseling (for positive test results) was accepted, linkage to care was provided, and partner notification was facilitated.

Engaging diverse community members to enhance analysis and interpretation: processing qualitative interview data

As the USA becomes more diverse, the inclusion of patients from diverse backgrounds in research becomes ever more important to ensuring a complete understanding of the patient experience in primary care. Language and cultural barriers are important areas in which researchers face substantial challenges. Primary care researchers need tools and approaches to include diverse communities in qualitative interviews. Here, we describe one way primary care researchers can apply an adapted, engaged transcription and interpretation method in qualitative research to improve retention of nuance and meaning across language and cultures, specifically with non-English, non-Spanish-speaking resettled refugees. We also discuss how the approach provided additional information that increased the validity of interpretation and analysis and improved the retention of nuance in a qualitative primary care study. The methodological and practical value, scope of application and potential limitations and improvements of this method through future research are addressed.

Recovery Capital among Migrants and Ethnic Minorities in Recovery from Problem Substance Use: An Analysis of Lived Experiences

Migrants and ethnic minorities (MEM) are known to be disadvantaged concerning risk factors for problem substance use and resources to initiate and sustain recovery (i.e., recovery capital). Yet, the voices of MEM are largely overlooked in recovery literature. This study explores recovery capital through 34 semi-structured interviews with a diverse sample of MEM in recovery in two ethnically diverse cities in Belgium. A Qualitative Content Analysis using recovery capital theory allowed us to identify various recovery resources on a personal, social, and community level. While physical and human recovery resources play a central role in participants' narratives, personal recovery capital is closely intertwined with meaningful social networks (i.e., social recovery capital) and recovery-supportive environments that maximize opportunities for building culturally sensitive recovery capital (i.e., community recovery capital). Though MEM-specific elements such as culture, migration background, stigma, and structural inequalities play a significant role in the recovery resources of MEM, the largely "universal" nature of recovery capital became clear. The narratives disclose a distinction between "essential" and "acquired" recovery capital, as well as the duality of some recovery resources. The need for developing recovery-oriented systems of care that are culturally responsive, diminish structural inequalities, and facilitate building recovery capital that is sensitive to the needs of MEM is emphasized.

Methodological and Ethical Considerations in Research With Immigrant and Refugee Survivors of Intimate Partner Violence

To promote safe and positive health outcomes by utilizing culturally relevant evidence-based interventions for immigrant and refugee women survivors of intimate partner violence, their active participation in research is critical. With 43.6 million immigrants and refugees living in the United States, there is a need for research studies to eliminate health disparities in these populations. However, barriers to recruiting and retaining these populations in research prevent the provision of quality and culturally informed services to meet their needs. The aim of this article is to discuss the recruitment and retention strategies employed and analyze the methodological and ethical challenges in the context of the weWomen Study. The use of a multifaceted approach informed by best practices maximized recruitment efforts and active participation that generated high numbers of immigrant and refugee women participants. The study also substantiated the need for more community-based participatory approaches to engage community members in the development of culturally appropriate approaches that instill a sense of ownership over the research process. Active research participation of immigrant and refugee survivors will help investigators understand their unique needs and facilitate the implementation of targeted evidence-based interventions.

Feasibility of a Web-Accessible Game-Based Intervention Aimed at Improving Help Seeking and Coping Among Sexual and Gender Minority Youth: Results From a Randomized Controlled Trial

PURPOSE

To address the gap in interventions for improving sexual and gender minority youth (SGMY; e.g., lesbian, gay, bisexual, and transgender youth) health, we tested the feasibility of a game-based intervention for increasing help-seeking, productive coping skills, resource knowledge/use, and well-being.

METHODS

We conducted a 2-arm randomized controlled trial testing a theory-based, community-informed, Web-accessible computer role-playing game intervention. Control condition received a list of resources. Primary hypotheses were high levels of implementation success, game demand, and game acceptability.

RESULTS

We randomized 240 SGMYs aged 14-18 years into the intervention (n = 120) or control (n = 120) conditions. Participants completed baseline (100%), 1-month follow-up (T2; 73.3%), and 2-month follow-up (T3; 64.4%) surveys. Among intervention participants, 55.8% downloaded and played the game. Of those who played, 46.2% reported a desire to play it again, and 50.8% would recommend it. Game acceptability exceeded hypothesized benchmarks, wherein participants reported high positive affect (M = 2.36; 95% confidence interval [CI]: 2.13, 2.58), low negative affect (M = 2.75; 95% CI: 2.55, 2.95), low tension/annoyance (M = 3.18; 95% CI: 2.98, 3.39), and high competence (M = 2.23; 95% CI: 2.04, 2.43) while playing the game. In multivariable intent-to-treat analyses of 38 secondary/tertiary outcomes, intervention participants reported significantly larger reductions than control participants in cyberbullying victimization (T2 b = -.28; 95% CI: -.56, -.01), binge drinking frequency (T2 b = -.39; 95% CI: -.71, -.06), and marijuana use frequency (T3 b = -2.78; 95% CI: -4.49, -1.08).

CONCLUSIONS

We successfully implemented a Web-accessible game trial with SGMY. The game-based intervention was feasible and acceptable to SGMY, and preliminary results show it improved several health-related behaviors. A larger scale trial is needed to test whether the game-based intervention can reduce health inequities for SGMY.

Sexual Debut Among Heterosexual Men of African and Caribbean Descent: Are the Youth Initiating Sex Earlier than the Older Generation?

Although age at first sex is considered a measure of sexual risk and vulnerability for HIV infection, there is a dearth of literature on age at sexual debut in the Canadian context. This study examined time variations to first sex among heterosexual African, Caribbean, and Black (ACB) men in four Ontarian cities. A population-based retrospective survey (n = 879) on timing to first sexual intercourse was conducted between 2018 and 2019 among self-identified heterosexual ACB men 16 years or older and residing in London, Ottawa, Toronto or Windsor. We used the lognormal survival analysis technique to examine variations in time to first sexual intercourse among age cohorts and between cities. The findings showed a generational shift in the pattern of sexual initiation, with younger heterosexual ACB men initiating sexual intercourse earlier compared with those currently older than 50 years. We observed those between 16 and 19 years, 20 and 29 years, and 30 and 39 years of age to have significantly higher risk ratios of TR = 0.852, TR = 0.869, and TR = 0.855, respectively. At city level, the results show marked spatial variations, with youth in cities of Toronto, Ottawa, and London at the highest risk of early sexual debut relative to those in Windsor. Early initiation of first sexual intercourse among heterosexual ACB youth was observed with those in the larger cities being at a relatively higher risk. There is the need for programs aimed at delaying sexual debut among youth in general. It is, however, important to recognize the relative risk of those in the larger cities.

Increasing the Uptake of HIV Testing among Men in Tanzania: A Novel Intervention for Bar Patrons

We investigated a novel community-based HIV testing and counseling (HTC) strategy by recruiting men from bars in northern Tanzania in order to identify new HIV infections. All bars in the town of Boma Ng'ombe were identified and male patrons were systematically invited to participate in a health study. HIV testing was offered to all enrolled participants. Outputs included HIV test yield, cost per diagnosis, and comparison of our observed test yield to that among male patients contemporaneously tested at five local facility-based HTC. We enrolled 366 participants and identified 17 new infections - providing a test yield of 5.3% (95% Confidence interval [CI] 3.3-8.4). The test yield among men contemporaneously tested at five local HTC centers was 2.1% (95% CI 1.6-2.8). The cost-per-diagnosis was $634. Our results suggest that recruiting male bar patrons for HIV testing is efficient for identifying new HIV infections. The scalability of this intervention warrants further evaluation.

Factors associated with access to health care among foreign residents living in Aichi Prefecture, Japan: secondary data analysis

BACKGROUND

In Japan, foreign residents, and particularly new arrivals in the country, experience barriers to health care and show poorer health outcomes when compared to Japanese nationals. The health-care-related situation for foreign residents in Japan has been characterized by drastic changes over time; thus, there is difficulty identifying individuals who are "left behind" by the system. In this study, we aimed to identify, among foreign residents who attended informal free medical consultations, factors associated with "being advised to visit a medical facility" and "being referred to a medical facility," which represented hypothetical proxy indicators of barriers to health care.

METHODS

Secondary data analyses were conducted using the activity records of a non-governmental organization that provides free consultations targeting foreign residents in various locations in Aichi Prefecture, Japan. Participant characteristics, including insurance coverage, were determined. Bivariate and multi-variate analyses were performed to identify factors associated with having barriers to health care.

RESULTS

Among 608 extracted cases, 164 (27.5%) cases were advised to visit a medical facility, and 72 (11.8%) were referred to a medical facility during the consultations. Those who were not covered by public insurance showed a 1.56-time (95% confidence interval [CI]: 1.19-2.05) higher prevalence of being advised to visit a medical facility when compared to those who were covered by public insurance. Unemployed people and students were more likely to be referred to a medical facility than were professional workers; the prevalence ratios were 3.28 (95% CI: 1.64-6.57) and 2.77 (95% CI: 1.18-6.46), respectively.

CONCLUSIONS

Although the majority were insured, almost 30% were advised to visit a medical facility, which implied that they had had limited access to the formal health-care system before availing of the free consultations. The findings highlight those uninsured, unemployed people and students, who are considered vulnerable to access to health care. It is vital to provide those who are vulnerable with the necessary support while updatinge evidence, so that no one is "left behind."

Long tracks of homozygosity predict the severity of alcohol use disorders in an American Indian population

Runs of homozygosity (ROH) arise when an individual inherits two copies of the same haplotype segment. While ROH are ubiquitous across human populations, Native populations-with shared parental ancestry arising from isolation and endogamy-can carry a substantial enrichment for ROH. We have been investigating genetic and environmental risk factors for alcohol use disorders (AUD) in a group of American Indians (AI) who have higher rates of AUD than the general U. S. population. Here we explore whether ROH might be associated with incidence and severity of AUD in this admixed AI population (n = 742) that live on geographically contiguous reservations, using low-coverage whole genome sequences. We have found that the genomic regions in the ROH that were identified in this population had significantly elevated American Indian heritage compared with the rest of the genome. Increased ROH abundance and ROH burden are likely risk factors for AUD severity in this AI population, especially in those diagnosed with severe and moderate AUD. The association between ROH and AUD was mostly driven by ROH of moderate lengths between 1 and 2 Mb. An ROH island on chromosome 1p32.3 and a rare ROH pool on chromosome 3p12.3 were found to be significantly associated with AUD severity. They contain genes involved in lipid metabolism, oxidative stress and inflammatory responses; and OSBPL9 was found to reside on the consensus part of the ROH island. These data demonstrate that ROH are associated with risk for AUD severity in this AI population.

Understanding Neighborhoods' Impact on Youth Substance Use and Mental Health Outcomes in Paterson, New Jersey: Protocol for a Community-Based Participatory Research Study

BACKGROUND

Substance use among youth is a major public health concern. Of note, substance use among youth is increasing in prevalence, and the incidence of substance use at earlier ages is rising. Given the long-term consequences of early substance use, it is important to identify factors that increase youth vulnerability to drug use, as they may be important targets for future interventions.

OBJECTIVE

This study aims to use innovative methods, such as venue-based sampling, to recruit youth who are disconnected from school and use community-based participatory research to gain a better understanding of the prevalence of substance use and important correlates among youth aged between 13 and 21 years in Paterson, New Jersey, a low-income, urban community. The study will use a convergent, mixed methods design involving multiple data collection components and the analysis of a ministrative data source, designed with the strengths of complex intervention frameworks in mind. The overall aims of the study are to identify the prevalence of substance use among youth who are engaged in school and not engaged in school; to understand important antecedents and correlates of substance use; and to use this information to inform social, environmental, and culturally appropriate interventions to address substance use and its correlates among youths in a lower-resourced urban community.

METHODS

This study will use both qualitative and quantitative methods to address important questions. Specifically, semistructured interviews using focus group and interview methodologies will be used to assess youths' lived experiences and will account for specific details that quantitative methods may not be able to attain. In addition, quantitative methods will be used to examine direct and multilevel associations between neighborhood factors and youth substance use and mental health outcomes.

RESULTS

A previous analysis from a substance use initiative in Paterson, New Jersey found that youth who use substances such as marijuana and alcohol are more likely to have higher rates of depression and anxiety. On the basis of the research questions, this study will examine the association between neighborhood characteristics, substance use, and mental health symptoms among youth in Paterson by using quantitative and qualitative methods and will use these findings to inform the adaptation of a community- and evidence-based substance use prevention intervention for these youths.

CONCLUSIONS

The findings of this study will provide an important contribution to understanding the role of socioecological factors in predicting substance use and mental health outcomes among youth in a lower-resourced, urban community. Furthermore, these findings will serve as evidence for the development of a culturally informed, community-based prevention program to address substance use disparities for youth, including those who are truant in Paterson, New Jersey.

An Innovative Approach to the Design of a National Probability Sample of Sexual Minority Adults

Purpose: Sampling lesbian, gay, and bisexual (LGB) people to recruit a national probability sample is challenging for many reasons, including the low base rate of LGB people in the population. To address this challenge, researchers have relied on diverse approaches to sampling LGB people. We aimed to test an innovative method to assemble a U.S. national probability sample of non-transgender sexual minority adults. Methods: Our approach used two phases. In Phase 1, we identified LGBT respondents in a probability general population sample. These respondents were then queried about their sexual orientation and gender identity using short screening questions to identify non-transgender sexual minority respondents. In Phase 2, the identified sexual minority respondents completed the targeted survey online or on a mailed questionnaire. Results: In Phase 1, using random-digit dialing, a nationally representative sample of 366,644 respondents were screened in a brief telephone interview. Of them, 3.5% (n = 12,837) identified as LGB or transgender. In Phase 2, eligible respondents were asked to participate in a self-administered survey questionnaire. Eligibility was based on gender identity, age, race and ethnicity, and educational restrictions. Of the 3525 who were eligible, 81% (n = 2840) agreed to participate in the study (78% agreed to use the web version and 22% the mailed questionnaire), and 49% of web surveys and 46% of mailed surveys were completed. The final sample included 1331 respondents. Conclusion: The benefits of this approach include the ability to assess sexual minority-specific content in a national probability sample; challenges include high cost and low base rates for Asian and American Indian or Alaska Native individuals in the United States.

GPS-estimated foot traffic data and venue selection for COVID-19 serosurveillance studies

The initial phase of the COVID-19 pandemic in the US was marked by limited diagnostic testing, resulting in the need for seroprevalence studies to estimate cumulative incidence and define epidemic dynamics. In lieu of systematic representational surveillance, venue-based sampling was often used to rapidly estimate a community’s seroprevalence. However, biases and uncertainty due to site selection and use of convenience samples are poorly understood. Using data from a SARS-CoV-2 serosurveillance study we performed in Somerville, Massachusetts, we found that the uncertainty in seroprevalence estimates depends on how well sampling intensity matches the known or expected geographic distribution of seropositive individuals in the study area. We use GPS-estimated foot traffic to measure and account for these sources of bias. Our results demonstrated that study-site selection informed by mobility patterns can markedly improve seroprevalence estimates. Such data should be used in the design and interpretation of venue-based serosurveillance studies.

Work Schedule Unpredictability: Daily Occurrence and Effects on Working Parents' Well-Being

OBJECTIVE

To investigate the pervasiveness and frequency of work schedule unpredictability among workers in low-wage hourly jobs and the effects of work schedule unpredictability on worker and family well-being.

BACKGROUND

Family science has long considered the ways in which parents' experiences in the workplace can affect families. Although unpredictability in work schedules has increased over time, especially for low-wage workers, the effects of schedule unpredictability on worker and family well-being have been understudied.

METHOD

Ninety-two workers with children aged 2-7, recruited using a new venue-time sampling technique, were asked to complete once-a-day surveys for 30 consecutive days (N = 2,221 person-days for analysis). Descriptive analyses and regression models with family fixed effects were utilized.

RESULTS

Work schedule unpredictability was common in the context of families' lives: over the 30 days, parents experienced an unanticipated work schedule change on 13.3% of days, and 87% of parents experienced at least one unanticipated work schedule change. Within families, unpredictable work schedule changes on a given day were associated with worse outcomes that day for parents, including increased negative mood and decreased perceived sleep quality.

CONCLUSION

Work schedule unpredictability is ubiquitous in the lives of low-wage hourly workers and is negatively related to working parents' well-being.

IMPLICATIONS

These results provide evidence that unscheduled and canceled shifts typical of low-wage service jobs may harm parents' well-being, which could ultimately affect their children's development and well-being.

Does a Rural Community-Based Intervention Improve Knowledge and Attitudes of Opioid Use Disorder and Medication-Assisted Treatment? A Report From the IT MATTTRs Study

Purpose

Understanding knowledge of and attitudes toward medication‐assisted treatment (MAT) for opioid use disorder (OUD) is important to changing the conversation about this devastating public health problem. While several studies report clinician knowledge and attitudes and training, less is known about community member perspectives. As part of the Implementing Technology and Medication Assisted Treatment Team Training in Rural Colorado study (IT MATTTRs), this study describes the implementation of community‐based interventions developed by rural community members and researchers to increase awareness and promote positive attitudes toward MAT for OUD and explores changes in community members’ OUD and MAT knowledge and beliefs.

Methods

Using the Boot Camp Translation process, the High Plains Research Network and Colorado Research Network MAT Advisory Councils developed multicomponent interventions on MAT for OUD. Baseline and postintervention surveys were administered using venue‐based sampling of community members in rural communities.

Findings

Surveys were completed by 789 community members at baseline and 798 at postintervention. Nearly half (49%) reported exposure to at least 1 intervention product. Greater exposure to intervention materials was associated with beliefs that using opioids to get high in rural communities is a problem (P < .0001), that opioid addiction is a chronic disease (P = .0032), and that OUD can be treated locally (P = .0003).

Conclusions

Partnering with local community members resulted in the successful development and implementation of community‐based interventions, exposure to which was associated with OUD knowledge and beliefs. Locally created interventions should be included in comprehensive approaches to stem the OUD epidemic.

Area based stratified random sampling using geospatial technology in a community-based survey

BACKGROUND

Most studies among Hispanics have focused on individual risk factors of obesity, with less attention on interpersonal, community and environmental determinants. Conducting community based surveys to study these determinants must ensure representativeness of disparate populations. We describe the use of a novel Geographic Information System (GIS)-based population based sampling to minimize selection bias in a rural community based study.

METHODS

We conducted a community based survey to collect and examine social determinants of health and their association with obesity prevalence among a sample of Hispanics and non-Hispanic whites living in a rural community in the Southeastern United States. To ensure a balanced sample of both ethnic groups, we designed an area stratified random sampling procedure involving three stages: (1) division of the sampling area into non-overlapping strata based on Hispanic household proportion using GIS software; (2) random selection of the designated number of Census blocks from each stratum; and (3) random selection of the designated number of housing units (i.e., survey participants) from each Census block.

RESULTS

The proposed sample included 109 Hispanic and 107 non-Hispanic participants to be recruited from 44 Census blocks. The final sample included 106 Hispanic and 111 non-Hispanic participants. The proportion of Hispanic surveys completed per strata matched our proposed distribution: 7% for strata 1, 30% for strata 2, 58% for strata 3 and 83% for strata 4.

CONCLUSION

Utilizing a standardized area based randomized sampling approach allowed us to successfully recruit an ethnically balanced sample while conducting door to door surveys in a rural, community based study. The integration of area based randomized sampling using tools such as GIS in future community-based research should be considered, particularly when trying to reach disparate populations.

Health status of female Moldovan migrants to Italy by health literacy level and age group: a descriptive study

BACKGROUND

Migration flows from Eastern Europe to Italy have been large and continue to grow. The purpose of this study was to examine the health status of a population of Moldovan migrant women, and their access to health care services in northern Italy, by age group and health literacy level.

METHODS

We administered an ad-hoc questionnaire to adult Moldovan women. A bivariate analysis was conducted to test the association between health literacy and age groups with other variables (lifestyles, symptoms and diseases, access to health services). A stepwise logistic regression analysis was run to test the association between access to primary care and health literacy. Moreover, the study compare Moldovan women data with a sample of Italian women of the same age range living in North-Eastern region.

RESULTS

Our sample included 170 Moldovan women (aged 46.5 ± 12.3) in five occupational categories: home care workers (28.2%); cleaners (27.1%); health care workers (5.9%); other occupations (28.8%); and unemployed (10%). Active smokers were twice as prevalent among the women with a low health literacy. Health literacy level also determined access to primary healthcare services. For all age groups, the Moldovan sample reported a higher prevalence of allergies, lumbar disorders and depression than the Italian controls.

CONCLUSIONS

The reported prevalence of some diseases was higher among Moldovan migrant women than among Italian resident women. Health literacy was associated with the migrant women's lifestyle and the use of primary health care services, as previously seen for the autochthonous population.

COVID-19 and Parent-Child Psychological Well-being

BACKGROUND AND OBJECTIVES

The outbreak of coronavirus disease 2019 has changed American society in ways that are difficult to capture in a timely manner. With this study, we take advantage of daily survey data collected before and after the crisis started to investigate the hypothesis that the crisis has worsened parents' and children's psychological well-being. We also examine the extent of crisis-related hardships and evaluate the hypothesis that the accumulation of hardships will be associated with parent and child psychological well-being.

METHODS

Daily survey data were collected between February 20 and April 27, 2020, from hourly service workers with a young child (aged 2-7) in a large US city (N = 8222 person-days from 645 individuals). A subsample completed a one-time survey about the effects of the crisis fielded between March 23 and April 26 (subsample n = 561).

RESULTS

Ordered probit models revealed that the frequency of parent-reported daily negative mood increased significantly since the start of the crisis. Many families have experienced hardships during the crisis, including job loss, income loss, caregiving burden, and illness. Both parents' and children's well-being in the postcrisis period was strongly associated with the number of crisis-related hardships that the family experienced.

CONCLUSIONS

Consistent with our hypotheses, in families that have experienced multiple hardships related to the coronavirus disease 2019 crisis, both parents' and children's mental health is worse. As the crisis continues to unfold, pediatricians should screen for mental health, with particular attention to children whose families are especially vulnerable to economic and disease aspects of the crisis.

Novel Recruitment Methods for Research Among Young Adults in Rural Areas Who Use Opioids: Cookouts, Coupons, and Community-Based Staff

OBJECTIVES

Rural communities in the United States are increasingly becoming epicenters of substance use and related harms. However, best practices for recruiting rural people who use drugs (PWUD) for epidemiologic research are unknown, because such strategies were developed in cities. This study explores the feasibility of web- and community-based strategies to recruit rural, young adult PWUD into epidemiologic research.

MATERIALS AND METHODS

We recruited PWUD from rural Kentucky to participate in a web-based survey about opioid use using web-based peer referral and community-based strategies, including cookouts, flyers, street outreach, and invitations to PWUD enrolled in a concurrent substance use study. Staff members labeled recruitment materials with unique codes to enable tracking. We assessed eligibility and fraud through online eligibility screening and a fraud detection algorithm, respectively. Eligibility criteria included being aged 18-35, recently using opioids to get high, and residing in the study area.

RESULTS

Recruitment yielded 410 complete screening entries, of which 234 were eligible and 151 provided complete, nonfraudulent surveys (ie, surveys that passed a fraud-detection algorithm designed to identify duplicate, nonlocal, and/or bot-generated entries). Cookouts and subsequent web-based peer referrals accounted for the highest proportion of screening entries (37.1%, n = 152), but only 29.6% (n = 45) of entries from cookouts and subsequent web-based peer referrals resulted in eligible, nonfraudulent surveys. Recruitment and subsequent web-based peer referral from the concurrent study yielded the second most screening entries (27.8%, n = 114), 77.2% (n = 88) of which resulted in valid surveys. Other recruitment strategies combined to yield 35.1% (n = 144) of screening entries and 11.9% (n = 18) of valid surveys.

CONCLUSIONS

Web-based methods need to be complemented by context-tailored, street-outreach activities to recruit rural PWUD.

Stigma, Resilience, and Health Care Use Among Transgender and Other Gender Diverse Youth in the United States

Purpose: To understand the relationships between stigma, resilience, and health care use among transgender and other gender diverse youth (TGDY). Methods: Data include a national sample of 171 TGDY (ages 15-24). Previously developed Gender Minority Stress Theory scales were used to measure experiences of stigma and resilience. Health care use included two outcomes: difficulty accessing care and medical gender affirmation service use (e.g., hormones and surgery). Principal components analysis (PCA) was used to reduce data. Logistic regression was used to test relationships between components and the outcomes; interactions between components were also tested. Results: The PCA determined three components representing (1) enacted stigma, (2) a positive sense of identity, and (3) social support. Two scales (mis-gendering and anticipated stigma) did not fit into any components and were included as separate variables. In the main effects model, none of the minority stress variables were associated with difficulty accessing care. However, an interaction between enacted stigma and a positive sense of identity indicated that having a more positive sense of identity was only associated with reduced difficulty accessing care for participants experiencing less stigma. For medical gender affirmation services, participants who experienced more anticipated stigma were less likely to use these services and participants with a more positive sense of identity were more likely to use them. Conclusions: Findings suggest that stigma and resilience experienced both inside and outside of health care settings can play a role on access to care for TGDY. Interventions should consider how to reduce stigma and promote resilience across multiple contexts.

Patterns of Sexual Risk Behavior, HIV Infection, and Use of Health Services Among Sub-Saharan African Migrants in Portugal

This study identified patterns of sexual risk behavior among a sub-Saharan African migrant (SAM) population in Portugal and examined its associations with human immunodeficiency virus (HIV) prevalence, sociodemographics, use of sexual health services, and HIV testing. A cross-sectional biobehavioral survey was conducted with a venue-based sample of 790 SAMs. Data were collected using questionnaires and rapid HIV tests. Cluster analysis identified five subgroups with differing levels of HIV infection (2.5% to 11.3%). In Cluster 1, most participants reported sexual abstinence over the past year and the remaining used condoms consistently; this cluster had the highest HIV prevalence (11.3%). In Cluster 2, most reported one sexual partner and all reported unprotected sex; all HIV-positive participants in this cluster were unaware of their HIV-positive status. In Clusters 3 and 4, most had four or more partners, yet all used condoms. In Cluster 3, 56.5% reported both regular and occasional partners. In Cluster 4, 74% had only occasional partners; all engaged in commercial sex. In Cluster 5, all reported four or more partners and condomless sex. In all subgroups we found low rates of HIV testing and high unawareness of HIV serostatus. Targeted prevention interventions are needed to reduce unprotected sexual relations and undiagnosed infection, as well as improve linkage to sexual health services.

REISNER SARI, W. HARPER GARY, E. GAMAREL KRISTI, STEPHENSON ROB. State-Level Transgender-Specific Policies, Race/Ethnicity, and Use of Medical Gender Affirmation Services among Transgender and Other Gender-Diverse People in the United States

Policy Points Protective transgender-specific policies (including those related to experiences of discrimination, health insurance coverage, and changing legal documents) are associated with increased access to medical gender affirmation services (hormone treatment, therapy/counseling) for transgender and other gender-diverse people. Restrictive transgender-specific policies are associated with less access to these services. The relationship between race/ethnicity and use of medical gender affirmation services varies across states and is context specific, indicating that race/ethnicity also plays a role in access to these types of care across states. Advocacy is needed to prevent or overturn restrictive policies and promote protective policies for transgender and other gender-diverse people, especially for people of color.

CONTEXT

In the 2010s, the number of federal, state, and local transgender-specific policies increased. Some of these policies advanced protections for transgender and other gender-diverse (TGGD) people, and others were restrictive. Little is known about the relationships between these policies and use of medical gender affirmation services (eg, hormone treatment, therapy/counseling), or about how these associations may vary among different racial and ethnic groups.

METHODS

Multilevel modeling was used to examine the associations between state-level transgender-specific policies and the use of medical gender affirmation services among TGGD people in the United States. Data are from the 2015 U.S. Trans Survey of nearly 28,000 TGGD people. The medical gender affirmation services examined in this study were hormone treatment and therapy/counseling. The state policies we analyzed addressed discrimination, health insurance coverage, and changing legal documents; these policies were measured individually and as a composite index. Race/ethnicity was included in the multilevel regression models as a random slope to determine whether the relationship between race/ethnicity and the use of medical gender affirmation services varied by state.

FINDINGS

Individual policies and the policy index were associated with both outcomes (use of therapy/counseling and hormone treatment services), indicating that protective policies were associated with increased care. Broad religious exemption laws and Medicaid policies that excluded transgender-specific care were both associated with less use of therapy/counseling, whereas transgender-care-inclusive Medicaid policies were associated with more use of therapy/counseling. Nondiscrimination protections that include gender identity were associated with increased use of hormone treatment services. The relationship between race/ethnicity and medical gender affirmation services varied across states.

CONCLUSIONS

State-level transgender-specific policies influence medical gender affirmation service use and seem to affect use by non-Hispanic white TGGD people and TGGD people of color differently. Advocacy is needed to repeal restrictive policies and promote protective policies in order to reduce health inequities among TGGD people, especially people of color.

Sexual health services in community pharmacy for women on opioid substitution treatment: a qualitative study

BACKGROUND

Women on opioid substitution treatment (WOST) are at heightened risk for the sexual transmission of sexually transmitted infections and blood-borne viruses. This study aimed to explore the opportunities to promote their sexual health in community pharmacies in UK.

METHODS

Semi-structured interviews were conducted with 20 WOST and 14 community pharmacists (CPs). A focus group was run with three CPs. Participants were recruited in drug services and a service for sex workers (WOST), and in CP. Data collection took place between October 2016 and September 2017. Data were analyzed using Framework Analysis and directed Content Analysis.

RESULTS

CPs could play a role in promoting sexual health among WOST. Sexual health screening, treatment and condom supply were suggested as potential ways of delivering pharmacy-based sexual health services. These services should be actively offered to WOST, delivered in a private space and free of cost. We identified several challenges to overcome in order to design and implement sexual health services for WOST in community pharmacies.

CONCLUSIONS

This study highlights the potentially key role CPs can have promoting sexual health and addressing health inequities among WOST. Improvements in pharmacists' training are required in order to address stigma towards WOST, and promote trust and positive rapport. Structural changes are also needed to broaden the services available for this group of women and improve their access to healthcare.
