Perceptions matter: Narratives of contraceptive implant robbery in Cape Town, South Africa.

Uptake of contraceptive implants has declined in South Africa since their introduction in 2014, with side effects and inadequate health provider training cited as primary contributors underlying a poor community perception of implants. In this paper we explore a theme that emerged unexpectedly during analysis of our research in Cape Town that may be an additional factor in this decline: narratives of women being assaulted by robbers who physically remove the implants for smoking as drugs. Narratives were described consistently across interviews and focus groups with youth (aged 18-24 years) and in interviews with health providers, with six participants (two young people, four health providers) sharing personal experiences of robbery. While there was a range of perspectives on whether narratives are based on real experiences or are myths, there was strong consensus that narratives of implant robbery may be influencing women's decisions around implant use in Cape Town. This is a potent example of how perceptions of new products can affect uptake and offers important lessons for implementers to reflect on in planning for rollout of other health technologies.

Women's Health and Mindfulness (WHAM): A Randomized Intervention Among Older Lesbian/Bisexual Women.

INTRODUCTION: Lesbian and bisexual (LB) women have higher body weight than heterosexual women. Interventions focused on health and well-being versus weight loss may be more likely to succeed among LB women. This article describes effects of Women's Health and Mindfulness, a 12-week pilot intervention addressing mindfulness, healthy eating, and physical activity, on outcomes associated with chronic disease risk among overweight and obese LB women older than 40 years. METHOD: Eighty women were randomized, using a stepped-wedge design, to either an immediate- or a delayed-start intervention group; the delayed-start group served as the control. Eligible participants were aged 40 years or older, identified as LB, and had a body mass index of 27 or greater. We compared differences in biological markers of chronic disease, mindfulness, nutrition, and physical activity between immediate- and delayed-start intervention groups. RESULTS: We observed clinically significant improvements in low-density lipoprotein cholesterol but no change in hemoglobin A1c. We found evidence of intervention effects on improved mindfulness and mindful eating scores and on nutrition (improved vegetable intake). CONCLUSIONS: The Women's Health and Mindfulness pilot intervention appears to have initiated positive behavioral and physical health changes in this population. Refinements to the intervention model, such as extended intervention duration, and longer term follow-up are warranted to determine sustained effects.

Seek, Test and Disclose: knowledge of HIV testing and serostatus among high-risk couples in a South African township.

OBJECTIVES: HIV testing and disclosure of results to partners is an important strategy in HIV prevention but is under-researched within heterosexual partnerships. To address this gap, we describe patterns of HIV testing, discrepancies between beliefs and biologically confirmed HIV status of each partner, and characteristics of mutually correct knowledge of HIV status among heterosexual couples in a high-prevalence community. METHODS: The study recruited 290 high-risk heterosexual couples in stable relationships from a township in Cape Town, South Africa. Male patrons of shebeens (drinking establishments) were approached to participate with their main partner in an intervention designed to reduce substance use, violence and unsafe sex. All participants were tested for HIV at baseline and asked about their partner's past HIV testing and current status. Using the couple as the unit of analysis, we conducted logistic regression to identify partnership and individual characteristics associated with having mutually correct knowledge of partner's HIV status. RESULTS: Half (52%) of women and 41% of men correctly knew whether their partner had ever been tested for HIV. 38% of women, 28% of men and in 17% of couples, both members reported mutually correct knowledge of their partner's HIV status. Correlates of correct knowledge included married/cohabitating (aOR 2.69, 95% CI 1.35 to 5.40), both partners HIV-negative (aOR 3.32 (1.38 to 8.00)), women's acceptance of traditional gender roles (aOR 1.17 (1.01 to 1.40)) and men's relationship satisfaction (aOR 2.22 (1.01 to 4.44)). CONCLUSIONS: Findings highlight the need to improve HIV testing uptake among men and to improve HIV disclosure among women in heterosexual partnerships. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov registration NCT01121692.

Differences in Chronic Disease Behavioral Indicators by Sexual Orientation and Sex.

CONTEXT: Lesbian, gay, and bisexual (LGB) populations experience significant health inequities in preventive behaviors and chronic disease compared with non-LGB populations. OBJECTIVES: To examine differences in physical activity and diet by sexual orientation and sex subgroups and to assess the influences of home and neighborhood environments on these relationships. DESIGN: A population-based survey conducted in 2013-2014. SETTING: A stratified, simple, random sample of households in 20 sites in the United States. PARTICIPANTS: A total of 21 322 adult LGB and straight-identified men and women. OUTCOME MEASURES: Any leisure-time physical activity in the past month; physical activity 150 min/wk or more; daily frequency of consumption of vegetables, fruit, water, and sugar-sweetened beverages; and the number of meals prepared away from home in the past 7 days. RESULTS: Physical activity and diet varied by sexual orientation and sex; differences persisted after adjusting for sociodemographic factors and household and community environments. Bisexual men reported a higher odds of engaging in frequent physical activity than straight men (odds ratio [OR] = 3.10; 95% confidence interval [CI], 1.57-6.14), as did bisexual women compared with straight women (OR = 1.84; 95% CI, 1.20-2.80). LGB subgroups reported residing in more favorable walking and cycling environments. In contrast, gay men and lesbian and bisexual women reported a less favorable community eating environment (availability, affordability, and quality of fruit and vegetables) and a lower frequency of having fruit or vegetables in the home. Lesbian women reported lower daily vegetable consumption (1.79 vs 2.00 mean times per day; difference = -0.21; 95% CI, -0.03 to -0.38), and gay men reported consumption of more meals prepared away from home (3.17 vs 2.63; difference = 0.53; 95% CI, 0.11-0.95) than straight women and men, respectively. Gay men and lesbian and bisexual women reported a higher odds of sugar-sweetened beverage consumption than straight men and women. CONCLUSIONS: Findings highlight opportunities for targeted approaches to promote physical activity and mitigate differences in diet to reduce health inequities.

Are hormonal contraceptive users more likely to misreport unprotected sex? Evidence from a biomarker validation study in Zimbabwe.

We analyzed biomarker validation data of unprotected sex from women in Zimbabwe to determine whether condom and sexual behavior misreporting differs between users of different contraceptive methods. Self-reported sexual behavior was compared with the presence of prostate-specific antigen (PSA) in vaginal fluid, a biomarker of semen exposure. Of the 195 women who were PSA positive, 94 (48 %) reported no sex or only condom-protected sex. Hormonal contraceptive users misreported sexual behavior less than women using non-hormonal methods (45 vs. 67 %, P = 0.03). This misclassification pattern could have implications on the elevated risk of HIV infection associated with hormonal contraception in some studies.

Biomarker validation of reports of recent sexual activity: results of a randomized controlled study in Zimbabwe.

Challenges in the accurate measurement of sexual behavior in human immunodeficiency virus (HIV) prevention research are well documented and have prompted discussion about whether valid assessments are possible. Audio computer-assisted self-interviewing (ACASI) may increase the validity of self-reported behavioral data. In 2006-2007, Zimbabwean women participated in a randomized, cross-sectional study that compared self-reports of recent vaginal sex and condom use collected through ACASI or face-to-face interviewing (FTFI) with a validated objective biomarker of recent semen exposure (prostate-specific antigen (PSA) levels). Of 910 study participants, 196 (21.5%) tested positive for PSA, an indication of semen exposure during the previous 2 days. Of these 196 participants, 23 (11.7%) reported no sex in the previous 2 days, with no difference in reported sexual activity between interview modes (12.5% ACASI vs. 10.9% FTFI; Fisher's exact test: P = 0.72). In addition, 71 PSA-positive participants (36.2%) reported condom-protected vaginal sex only; their reports also indicated no difference between interview modes (33.7% ACASI vs. 39.1% FTFI; P = 0.26). Only 52% of PSA-positive participants reported unprotected sex during the previous 2 days. Self-report was a poor predictor of recent sexual activity and condom use in this study, regardless of interview mode, providing evidence that such data should be interpreted cautiously.
