RESUMEN

Objectives. To evaluate Chicas Creando Acceso a la Salud (Girls Creating Access to Health; ChiCAS), a Spanish-language, small-group intervention designed to increase preexposure prophylaxis (PrEP) use, consistent condom use, and medically supervised gender-affirming hormone therapy use among Spanish-speaking transgender Latinas who have sex with men. Methods. Participants were 144 HIV-negative Spanish-speaking transgender Latinas, aged 18 to 59 years, living in North and South Carolina. From July 2019 to July 2021, we screened, recruited, and randomized them to the 2-session ChiCAS intervention or the delayed-intervention waitlist control. Participants completed assessments at baseline and 6-month follow-up. Follow-up retention was 94.4%. Results. At follow-up, relative to control participants, ChiCAS participants reported increased PrEP use (adjusted odds ratio [AOR] = 4.64; 95% confidence interval [CI] = 1.57, 13.7; P < .006). However, ChiCAS participants did not report increased use of condoms or medically supervised gender-affirming hormone therapy. ChiCAS participants reported increases in knowledge of HIV (P < .001), sexually transmitted infections (P < .001), and gender-affirming hormone therapy (P = .01); PrEP awareness (P < .001), knowledge (P < .001), and readiness (P < .001); condom use skills (P < .001); and community attachment (P < .001). Conclusions. The ChiCAS intervention was efficacious in increasing PrEP use among Spanish-speaking, transgender Latinas in this trial.

RESUMEN

Trans women experience multiple forms of intersecting stigma due to trans identity, HIV, and sex work, which can negatively affect their health. There is limited understanding of the relationships between stigma and HIV care and treatment outcomes. We assessed associations between multiple forms and types of stigma and HIV treatment outcomes among trans women who conduct sex work in Santo Domingo, Dominican Republic using cross-sectional survey data. Most participants had received HIV care (91%) and were currently taking anti-retroviral therapy (ART) (84%). Only 64% were virally suppressed. Nearly one-third (32%) had interrupted ART at some point; those who had never interrupted ART were more likely to be suppressed. Drug use was associated with ART interruption. Higher enacted HIV stigma was associated with current ART use. Higher enacted HIV stigma and higher anticipated sex work stigma were associated with ART adherence. Higher trans stigma was associated with being virally suppressed. Findings highlight the importance of addressing multiple forms of stigma at the individual and clinic levels to improve and sustain viral suppression. Future research is needed to assess if unexpected associations between stigma and HIV outcomes reflect processes of resilience. Future research is also needed to assess the pathways between drug use, ART interruption, and viral suppression among trans women.

RESUMEN

Objectives: Mental health concerns (e.g. depression, anxiety) that negatively impact gay, bisexual, and other men who have sex with men (GBMSM) persist over the life course and into old age, but less is known about potential contributors to GBMSM's mental health. Close relationships can be a source of risk or resilience from stress, exerting direct relationships on mental health, and may mediate well-established associations between minority stress and mental health. This study examined whether primary partner relationship support and strain were uniquely associated with, and mediated the association between internalized homophobia, and mental health among older GBMSM.Methods: GBMSM (N = 517, M age = 60) from the Multicenter AIDS Cohort Study, who were in primary relationships with men, provided self-report data at four timepoints. We used multilevel modeling to examine longitudinal associations among relationship support and strain and internalized homophobia with depression and anxiety.Results: Relationship strain, but not support, was positively associated with mental health concerns longitudinally. There was a significant, positive indirect effect of internalized homophobia on depression and anxiety through strain, but no support. Internalized homophobia was positively associated with relationship strain, which was positively associated with mental health symptoms longitudinally.Conclusions: Relationship strain was associated with depression and anxiety longitudinally among middle-aged and older GBMSM and mediated associations of internalized homophobia with mental health. The role of partner support warrants further investigation. Mental health interventions are critically needed for older GBMSM and, for partnered GBMSM, should include strategies for reducing relationship strain to foster well-being.

RESUMEN

BACKGROUND: Medical gender affirmation (i.e., hormone use) is one-way transgender (trans) people affirm their gender and has been associated with health benefits. However, trans people face stigmatization when accessing gender-affirming healthcare, which leads some to use non-prescribed hormones (NPHs) that increase their risk for poor health. PURPOSE: We examined whether healthcare policy stigma, as measured by state-level trans-specific policies, was associated with NPHs use and tested mediational paths that might explain these associations. Because stigmatizing healthcare policies prevent trans people from participation in healthcare systems and allow for discrimination by healthcare providers, we hypothesized that healthcare policy stigma would be associated with NPHs use by operating through three main pathways: skipping care due to anticipated stigma in healthcare settings, skipping care due to cost, and being uninsured. METHODS: We conducted analyses using data from the 2015 U.S. Transgender Survey. The analytic sample included trans adults using hormones (N = 11,994). We fit a multinomial structural equation model to examine associations. RESULTS: Among trans adults using hormones, we found that healthcare policy stigma was positively associated with NPHs use and operated through insurance coverage and anticipating stigma in healthcare settings. The effect sizes on key predictor variables varied significantly between those who use supplemental NPHs and those who only use NPHs suggesting the need to treat NPHs use as distinct from those who use supplemental NPHs. CONCLUSIONS: Our work highlights the importance of healthcare policy stigma in understanding health inequities among trans people in the USA, specifically NPHs use.

RESUMEN

BACKGROUND: Transgender and other gender diverse (TGD) youth of color experience stigma within healthcare. Gender affirmation can be a resilience resource; however, little is known about gender affirmation within healthcare. PURPOSE: This study explores TGD youth of color's experiences of stigma and gender affirmation across the entire healthcare experience and their role on motivation to seek care. METHODS: In 2015, cross-sectional surveys and individual in-depth interviews were conducted among 187 TGD youth ages 16-24 living in 14 U.S. cities. Analyses followed a mixed-methods design whereby 33 participants were purposively selected for a qualitative phenomenological analysis based on quantitatively reported gender affirmation needs. Subsequent quantitative analyses examined how healthcare use differed by access to gender affirmation. RESULTS: Participants qualitatively described experiencing stigma across multiple healthcare settings (e.g., primary care, emergency care, medical gender affirmation), including before (finding providers, scheduling), during (waiting rooms, provider interactions), and after (pharmacy) healthcare visits. Participants who quantitatively reported access to gender-affirming healthcare still described negative healthcare experiences, either because they accessed multiple healthcare services or because of prior negative experiences. Stigma and gender affirmation (both inside and outside of healthcare) influenced motivation to seek care, with variation depending on the type of care. Quantitative analyses confirmed these findings; access to gender affirmation differed for participants who delayed primary care vs. those who did not, but did not vary based on participants' use of medical gender affirmation. CONCLUSIONS: Findings highlight the importance of promoting gender-affirming healthcare environments to increase access to care for TGD youth of color.

RESUMEN

BACKGROUND: Brief behavioral interventions are seen as an efficient way to improve knowledge, change behavior, and reduce provider stigma regarding sexual health. When grounded in evidence-based behavioral change techniques and delivered using Brief Sexuality-related Communication (BSC) tools, brief behavioral interventions can address client-driven sexual health goals in a single session with their provider. Evidence for the efficacy of brief interventions for creating gains in sexual health comes largely from resource rich settings, and there is a lack of knowledge of how brief interventions can be implemented in the more resource constrained environments of low- and middle-income countries. As a first step in developing a brief intervention to address sexual health issues in Moldova, this paper reports on qualitative data collected from Moldovan providers to understand their attitudes, willingness and perceived barriers to the brief intervention and its implementation. METHODS: Thirty-nine in-depth interviews (IDI) were conducted between February and March 2020, with health providers recruited from three primary health care institutions, two Youth Friendly Health Centers and counselors from three NGOs who work with key populations in Moldova, including health centers selected from two cites - the capital city, Chisinau and from the Comrat Region. The IDI addressed four domains of provider attitudes: 1) attitudes towards the intervention; 2) willingness and motivation to implement the intervention; 3) logistics of providing the intervention and 4) ability to implement the intervention. A coding analysis approach was applied to all interview transcripts. RESULTS: Providers largely reported being willing to be trained in and implement the brief intervention. Willingness to implement the intervention stemmed from two perceptions: that it would improve the ability of providers to talk with their clients about sex, and that vulnerable groups would benefit from these conversations. However, while there were generally positive attitudes towards the intervention, providers consistently reported structural barriers to their perceived ability to implement the intervention. CONCLUSIONS: While providers reported high levels of initial acceptance of a brief behavioral intervention, care is needed to ensure that brief interventions, and the training of providers on brief interventions, incorporate cultural attitudes and norms around sex, particularly in highly patriarchal settings, and provide opportunities for providers to practice the intervention in ways that address their assumptions and implicit biases.

RESUMEN

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.

RESUMEN

Young men who have sex with men (YMSM) between the ages of 13 and 24 account for a disproportionate number of new HIV infections in the U.S. Recognizing the unique developmental circumstances that YMSM face and building on the dual-process model, it is important to consider the role of cognitive and emotional factors as well as self-efficacy to negotiate safer sex when understanding experiences of sexual risk-taking among YMSM. This article used structural equation modeling to examine how the decisional balance to use condoms (a cognitive factor) and limerence (an emotional factor) are both directly and indirectly associated with sexual risk-taking behaviors (the number of insertive and receptive condomless anal intercourse partners), with indirect effects occurring via limited self-efficacy to negotiate safer sex. Data were from a cross-sectional online survey of YMSM (aged 18-24) in the U.S. who did not report being in a romantic relationship. Analysis included a sample of 1084 single YMSM who had never tested positive for HIV and who had engaged in anal intercourse in the previous 2 months. Results indicated that the decisional balance to use condoms was both directly and indirectly associated with reduced sexual risk-taking behaviors. Limerence was not directly associated with sexual risk-taking behaviors; however, it was indirectly associated with sexual risk-taking behavior through limited self-efficacy to negotiate safer sex. These findings highlight the importance of considering both cognitive and emotional factors, as well as self-efficacy to use condoms, in the development and implementation of HIV prevention interventions for YMSM.

RESUMEN

This study uses longitudinal qualitative methods to examine how gay and bisexual men perceive sexual risk across both a variety of partners and across time. Over ten weeks, participants completed three quantitative personal relationship diaries (PRD) describing sexual encounters during that time period. Participants then completed a timeline-based individual in-depth interview to unpack the PRD data. Participants used multiple factors to determine their own sexual risk (e.g., type of sex, partner concurrency, emotional connections), which often resulted in inconsistencies in defining sexual risk and determining the level of risk both within and across partners and across time. These findings can inform HIV prevention messages and programming.

RESUMEN

In countries such as the USA, gay and bisexual men experience high rates of intimate partner violence. However, little is known about the factors that contribute to this form of violence. In this study, we examine gay and bisexual men's perceptions of sources of tension in same-sex male relationships and how these may contribute to intimate partner violence. We conducted seven focus-group discussions with 64 gay and bisexual men in Atlanta, GA. Focus groups examined men's reactions to the short-form revised Conflicts Tactics Scale to determine if each item was considered to be intimate partner violence if it were to occur among gay and bisexual men. Analysts completed a thematic analysis, using elements of grounded theory. The sources of tension that men identified included: gender role conflict, dyadic inequalities (e.g. differences in income, age, education), differences in 'outness' about sexual identity, substance use, jealousy and external homophobic violence. Results suggest that intimate partner violence interventions for gay and bisexual men should address behavioural factors, while also focusing on structural interventions. Interventions that aim to reduce homophobic stigma and redefine male gender roles may help to address some of the tension that contributes to intimate partner violence in same-sex male relationships.

RESUMEN

Recent studies have called for more nuanced research into the relationships between behaviourally bisexual men and their sexual partners. To address this, we conducted a longitudinal qualitative study with self-identifying gay men; participants took part in timeline-based interviews and relationship diaries. We conducted a thematic analysis of verbatim transcripts to understand how relationship motivations, emotions and relationship dynamics influenced perceptions of HIV risk with behaviourally bisexual male partners. Participants described how partnership types (main and casual) and relationship dimensions (exclusivity, commitment, emotional attachment and relationship designation) strongly influenced perceptions of HIV risk and shaped their decisions to choose behaviourally bisexual male sex partners. Results reveal the crucial role relationship dynamics play in the shaping of HIV risk perceptions, sexual decision-making and HIV risk between partners, and provide potential insight on how to message HIV risk to gay men and their behaviourally bisexual male partners. It is imperative that HIV prevention is able to message key concepts of risk, decision-making and partner negotiation in a way that does not act to stereotype or create stigma against behaviourally bisexual men and their male partners.

RESUMEN

Men who have sex with men (MSM) remain the most severely affected risk group in the US HIV/AIDS epidemic. One-third to two-thirds of HIV transmissions among MSM are estimated to come from primary sex partners. Couples HIV testing and counseling (CHTC), in which two individuals receive pre-test counseling, HIV testing and post-test prevention planning together, has been adapted for male couples in the USA, and is now available in more than 30 cities. Previous studies have demonstrated high levels of willingness to use CHTC among MSM, but to date no studies have explored this among Latino MSM (LMSM). To examine the willingness to use CHTC among and further cultural adaptation needed for LMSM, focus group discussions were held with men who self-identified as Latino, were in a relationship with another man, and resided in Seattle. Willingness to use CHTC was high. Participants reported that CHTC could strengthen and validate their relationships, help mitigate stigma, and provide a forum for support, protection, and information sharing. Barriers to CHTC use included fears of rejection, loneliness, and relationship dissolution, and concerns around deportation and financial burden. The high levels of reported willingness to use CHTC among this sample of LMSM point to the potential for CHTC to be further adapted to provide dyadic HIV testing services for LMSM.

RESUMEN

Men who have sex with men account for a disproportionate burden of HIV incidence in the USA. Although much research has examined the drivers of sexual risk-taking, the emotional contexts in which men make sexual decisions has received little attention. In this three-phase, 10-week longitudinal qualitative study involving 25 gay and bisexual men, we used timeline-based interviews and quantitative web-based diaries about sexual and/or dating partners to examine how emotions influence HIV risk perceptions and sexual decision-making. Participants described love, intimacy, and trust as reducing HIV risk perceptions and facilitating engagement in condomless anal intercourse. Lust was not as linked with risk perceptions, but facilitated non condom-use through an increased willingness to engage in condomless anal intercourse, despite perceptions of risk. Results indicate that gay and bisexual men do not make sexual decisions in an emotional vacuum. Emotions influence perceptions of risk so that they do not necessarily align with biological risk factors. Emotional influences, especially the type and context of emotions, are important to consider to improve HIV prevention efforts among gay and bisexual men.

RESUMEN

Research demonstrates that stigma and resilience influence transgender peoples' healthcare use. Less is known about transgender Latinas in the U.S. South who face multilevel barriers to healthcare access. We used baseline data from the ChiCAS intervention study. Using logistic regression, we examined how stigma (perceived discrimination related to gender identity, race/ethnicity, sexual behavior and perceived documentation status and internalized transphobia), and resilience (ethnic group pride and social support) are associated with two healthcare outcomes (use of routine medical care and medically supervised gender-affirming hormones). We also explored barriers to accessing both types of care. After removing 13 participants with missing data, our sample size was 131 transgender Latinas in the U.S. South. Most participants (74.8%, n = 98) received routine medical care in the past year and 57.3% (n = 75) had ever received medically supervised gender-affirming hormones. Reports of discrimination were highest for gender identity and documentation status. Race/ethnicity-based discrimination was positively associated with accessing routine medical care in the past year (OR = 1.94, p = 0.048). Having more social support was positively associated with care (routine care: OR = 3.48, p = 0.002 and gender-affirming hormones: OR = 2.33, p = 0.003). The most commonly reported barriers to accessing both types of care included cost, insurance, and not knowing where to go. Findings highlight the importance of social support for healthcare use among transgender Latinas. Social support may be especially important when considering the unique experiences of discrimination faced by transgender Latinas in the U.S. South.

RESUMEN

Evidence from observational studies and randomised trials has suggested a potential association between intake of n-3 long-chain polyunsaturated fatty acids (LCPUFA) during pregnancy and certain pregnancy and birth outcomes. Marine foods (e.g. fatty sea fish, algae) and select freshwater fish contain pre-formed n-3 LCPUFA, which serve as precursors for bioactive molecules (e.g. prostaglandins) that influence a variety of biological processes. The main objective of this analysis was to summarise evidence of the effect of n-3 LCPUFA intake during pregnancy on select maternal and child health outcomes. Searches were performed in PubMed, EMBASE, and other electronic databases to identify trials where n-3 LCPUFA were provided to pregnant women for at least one trimester of pregnancy. Data were extracted into a standardised abstraction table and pooled analyses were conducted using RevMan software. Fifteen randomised controlled trials were eligible for inclusion in the meta-analysis, and 14 observational studies were included in the general review. n-3 LCPUFA supplementation during pregnancy resulted in a modest increase in birthweight (mean difference = 42.2 g; [95% CI 14.8, 69.7]) and no significant differences in birth length or head circumference. Women receiving n-3 LCPUFA had a 26% lower risk of early preterm delivery (<34 weeks) (RR = 0.74; [95% CI 0.58, 0.94]) and there was a suggestion of decreased risk of preterm delivery (RR = 0.91; [95% CI 0.82, 1.01]) and low birthweight (RR = 0.92; [95% CI 0.83, 1.02]). n-3 LCPUFA in pregnancy did not influence the occurrence of pre-eclampsia, high blood pressure, infant death, or stillbirth. Our review of observational studies revealed mixed findings, with several large studies reporting positive associations between fish intake and birthweight and several reporting no associations. In conclusion, n-3 LCPUFA supplementation during pregnancy resulted in a decreased risk of early preterm delivery and a modest increase in birthweight. More studies in low- and middle-income countries are needed to determine any effect of n-3 LCPUFA supplementation in resource-poor settings, where n-3 PUFA intake is likely low.

RESUMEN

Current understanding of biologic processes indicates that women's nutritional status before and during early pregnancy may play an important role in determining early developmental processes and ensuring successful pregnancy outcomes. We conducted a systematic review of the evidence for the impact of maternal nutrition before and during early pregnancy (<12 weeks gestation) on maternal, neonatal and child health outcomes and included 45 articles (nine intervention trials and 32 observational studies) that were identified through PubMed and EMBASE database searches and examining review articles. Intervention trials and observational studies show that periconceptional (<12 weeks gestation) folic acid supplementation significantly reduced the risk of neural tube defects. Observational studies suggest that preconceptional and periconceptional intake of vitamin and mineral supplements is associated with a reduced risk of delivering offspring who are low birthweight and/or small-for-gestational age (SGA) and preterm deliveries (PTD). Some studies report that indicators of maternal prepregnancy size, low stature, underweight and overweight are associated with increased risks of PTD and SGA. The available data indicate the importance of women's nutrition prior to and during the first trimester of pregnancy, but there is a need for well-designed prospective studies and controlled trials in developing country settings that examine relationships with low birthweight, SGA, PTD, stillbirth and maternal and neonatal mortality. The knowledge gaps that need to be addressed include the evaluation of periconceptional interventions such as food supplements, multivitamin-mineral supplements and/or specific micronutrients (iron, zinc, iodine, vitamin B-6 and B-12) as well as the relationship between measures of prepregnancy body size and composition and maternal, neonatal and child health outcomes.

RESUMEN

Supplementation with multiple micronutrients (MM) during pregnancy may result in improved pregnancy and infant outcomes. We conducted meta-analyses of randomised controlled trials that evaluated the effects of prenatal supplementation with MM (defined as containing at least five micronutrients and typically included iron or iron and folic acid). The outcomes of interest were low birthweight (<2500 g), birthweight, small-for-gestational age (SGA), gestational age, preterm birth (<37 weeks' gestation), stillbirth and neonatal death, maternal morbidity and mortality. We identified eligible studies through PubMed and EMBASE database searches. Meta-analyses were performed by pooling results for outcomes that were reported from more than one trial and sub-analyses were conducted to evaluate the effect of timing of intervention and amount of iron. We included published results from 16 trials in this review. Compared with control supplementation that was usually iron plus folic acid in most studies, MM supplementation resulted in a significant reduction in the incidence of low birthweight [pooled risk ratio (RR) 0.86; 95% confidence interval (CI) 0.81, 0.91] and SGA (pooled RR 0.83 [95% CI 0.73, 0.95]) and an increase in mean birthweight (weighted mean difference (WMD) 52.6 g [95% CI 43.2 g, 62.0 g]). There was no significant difference in the overall risk of preterm birth, stillbirth, and maternal or neonatal mortality, but we found an increased risk of neonatal death for the MM group compared with iron-folate in the subgroup of five trials that began the intervention after the first trimester (RR 1.38 [95% CI 1.05, 1.81]). None of the studies evaluated maternal morbidity. Compared with iron plus folic acid supplementation alone, prenatal maternal supplementation with MM resulted in a reduction in the incidence of low birthweight and SGA but increased risk of neonatal death in the subgroup of studies that began the intervention after the first trimester.

RESUMEN

INTRODUCTION: Globally, transgender and other gender diverse (trans) people face pervasive stigma, which contributes to health inequities across multiple health outcomes. Stigma is a fundamental cause of health inequities because it simultaneously limits access to resources, contributes to systemic vulnerability and generates chronic stress. Anti-trans stigma occurs across multiple socioecological levels, resulting in multiple possible definitions and measurements of trans stigma. Understanding how trans stigma has been measured in low-income and middle-income countries (LMICs) is critical to health promotion efforts for trans communities. Accordingly, this scoping review will identify and examine how anti-trans stigma has been measured in existing LMIC-specific research to inform best practices for measurement of anti-trans stigma that includes consideration of local context. METHODS AND ANALYSIS: This is the protocol for a scoping review of anti-trans stigma in LMICs. We will search (from January 2001 to December 2021) PubMed, WHO Global Medicus and EBSCO. Study selection will conform to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews Checklist. Original studies in English, Spanish, Arabic or Russian will be included. Reviewers will independently screen all citations, full-text articles and abstract data. Data analysis will involve quantitative and qualitative methods. A narrative summary of findings will be conducted. ETHICS AND DISSEMINATION: As a scoping review (no direct interaction with participants), this study is exempt from human subjects oversight. Understanding context-specific ways to measure anti-trans stigma is urgently needed to support trans health globally. The planned scoping review will help to address this gap. Results of the review will be disseminated in a peer-reviewed journal and likely in other media such as conferences, seminars and symposia. PROTOCOL REGISTRATION NUMBER: osf.io/qcs2v.

RESUMEN

The COVID-19 pandemic has profoundly affected the conduct of community-based and community-engaged research. Prior to the pandemic, our community-based participatory research partnership was testing ChiCAS, an in-person, group-level behavioral intervention designed to promote uptake of pre-exposure prophylaxis (PrEP), condom use, and medically supervised gender-affirming hormone therapy among Spanish-speaking transgender Latinas. However, the pandemic required adaptations to ensure the safe conduct of the ChiCAS intervention trial. In this article, we describe adaptations to the trial within five domains. Transgender women are disproportionately affected by HIV, and it is essential to find ways to continue research designed to support their health within the context of the COVID-19 pandemic and future infectious disease outbreaks, epidemics, and pandemics. These adaptations offer guidance for ongoing and future community-based and community-engaged research during the COVID-19 pandemic and/or potential subsequent outbreaks (e.g., monkeypox), epidemics, and pandemics, particularly within under-served marginalized and minoritized communities.

RESUMEN

Micronutrient deficiencies are common and often co-occur in many developing countries. Several studies have examined the benefits of providing multiple micronutrient (MMN) interventions during pregnancy and childhood, but the implications for programs remain unclear. The key objective of this review is to summarize what is known about the efficacy of MMN interventions during early childhood on functional outcomes, namely, child health, survival, growth, and development, to guide policy and identify gaps for future research. We identified review articles including meta-analyses and intervention studies that evaluated the benefits of MMN interventions (3 or more micronutrients) in children (<5 y of age) using Pubmed and EMBASE. Several controlled trials (n = 45) and meta-analyses (n = 6) have evaluated the effects of MMN interventions primarily for child morbidity, anemia, and growth. Two studies found no effects on child mortality. The findings for respiratory illness and diarrhea are mixed, although suggestive of benefit when provided as fortified foods. There is evidence from several controlled trials (>25) and 2 meta-analyses that MMN interventions improve hemoglobin concentrations and reduce anemia, but the effects were small compared to providing only iron or iron with folic acid. Two recent meta-analyses and several intervention trials also indicated that MMN interventions improve linear growth compared to providing a placebo or single nutrients. Much less is known about the effects on MMN interventions during early childhood on motor and mental development. In summary, MMN interventions may result in improved outcomes for children in settings where micronutrient deficiencies are widespread.
