Intimate Partner Violence (IPV) and Associated Factors in HPTN 071 (PopART) Study Communities in Zambia and South Africa-A Comparison by HIV Status.

The HPTN 071(PopART) study was a community-randomised trial in Zambia and South Africa, examining the impact of combination-prevention including universal testing and treatment (UTT), on HIV-incidence. This sub-study evaluated factors associated with IPV (physical and/or sexual) to identify differences by HIV status. During 2015-16, a random subset of adults who participated in the first year of the PopART intervention were recruited and standardised questionnaires were administered. Logistic regression was performed to estimate odds ratios of factors associated with IPV. Among > 700 women studied (300 HIV-negative;400 HIV-positive), ~ 20% reported experiencing physical and/or sexual violence in the last 12-months. Sexual violence was similar by HIV status, but physical violence and reporting both physical/sexual violence was more common among HIV-positive women. Spending nights away from the community in the last 12-months was associated with higher odds of IPV among both HIV-negative (aOR 3.17, 95% CI 1.02-9.81) and HIV-positive women (aOR 1.79, 95% CI 0.99-3.24). Among HIV-positive women, financial autonomy was associated with reduced IPV (aOR:0.41,95%CI:0.23-0.75) while pregnancy in the last 12-months (aOR 2.25, 95% CI 1.07-4.74), risk of alcohol dependence (aOR 2.75, 95% CI 1.51-5.00) and risk of mental distress (aOR 2.62, 95% CI 1.33-5.16) were associated with increased IPV. Among HIV-negative women reporting sex in the last 12-months, transactional sex (aOR 3.97, 95% CI 1.02-15.37) and not knowing partner's HIV status (aOR 3.01, 95% CI 1.24-7.29) were associated with IPV. IPV was commonly reported in the study population and factors associated with IPV differed by HIV status. The association of mobility with IPV warrants further research. The high prevalence of harmful alcohol use and mental distress, and their association with IPV among HIV-positive women require urgent attention.

RESUMEN: El estudio HPTN 071 (PopART) fue un ensayo aleatorio-comunitario realizado en Zambia y Sudáfrica, que examinó el impacto de la prevención combinada, incluyendo las pruebas y tratamiento universal (UTT), en la incidencia del VIH. Este subestudio evaluó los factores asociados con la IPV (físicos y / o sexuales) para identificar diferencias en el estado del VIH. Durante 2015-16, un subconjunto aleatorio de adultos fueron reclutados para participar en el primer año de intervención de PopART, donde se administraron cuestionarios estandarizados. Se realizó una regresión logística para estimar las ratios de probabilidad de los factores asociados con la VPI. Entre las > 700 mujeres estudiadas (300 VIH negativas; 400 VIH positivas), ~ 20% informó haber experimentado violencia física y / o sexual en los últimos 12 meses. La violencia sexual fue similar en cuanto al estado del VIH. La denuncia de violencia física y sexual fue más común entre las mujeres VIH positivas. Pasar noches fuera de la comunidad en los últimos 12 meses, se asoció con mayores probabilidades de VPI entre las mujeres VIH negativas (ORa 3,17, 95% IC 1,02­9,81) y las mujeres VIH positivas (ORa 1,79, 95% IC 0,99­3,24). Entre las mujeres VIH positivas, la autonomía financiera se asoció con una reducción de la VPI (ORa 0,41; IC del 95% 0,23-0,75) mientras que en el embarazo en los últimos 12 meses (ORa 2,25; IC del 95% 1,07­4,74), riesgo a la dependencia del alcohol (ORa 2,75% IC 1,51­5,00) y el riesgo de angustia mental (ORa 2,62% IC del 95% 1,33­5,16) se asociaron con un aumento de la VPI. Entre las mujeres VIH negativas que informaron haber tenido relaciones sexuales en los últimos 12 meses, el sexo transaccional (ORa 3.97, 95% CI 1.02­15.37) y el desconocimiento del estado de VIH de la pareja (ORa 3.01, 95% CI 1.24­7.29) se asociaron con IPV. La IPV fue notificada mayoritariamente en la población de estudio y los factores asociados con la IPV diferían según el estado del VIH. La asociación de la movilidad con la IPV justifica una mayor investigación. La alta prevalencia de l consumo nocivo de alcohol y la angustia mental, y su asociación con la VPI entre las mujeres seropositivas, requieren atención urgente.

Intimate partner violence and HIV treatment adherence in urban South Africa: Mediating role of perinatal common mental disorders.

Background: Antiretroviral therapy (ART) has potential to eliminate perinatal HIV infections, but adherence to ART in late pregnancy and postpartum is often suboptimal. Intimate partner violence (IPV) may influence non-adherence among perinatal women living with HIV (WWH), but few quantitative studies have examined this over time or explored mechanisms for this association. Methods: We used secondary data from a parent trial in Johannesburg comprising WWH from the control arm (n=63) and WWH ineligible for the trial (n=133). Trained nurse researchers administered questionnaires at first antenatal visit on past-year psychological, physical, and/or sexual IPV (WHO instrument), socio-demographics (age, food security, education), and perinatal common mental symptoms of depression (Hospital Anxiety and Depression Screener-d); anxiety (HADS-a); post-traumatic stress disorder (PTSD; Harvard Trauma Questionnaire). At endline visit 2-4 months postpartum, nurse researchers assessed self-reported ART adherence using a visual analog scale (with ≥95% considered "good"). We fitted structural equation models (SEM) in MPlus to explore direct and indirect effects of IPV on ART adherence. Results: Of 196 perinatal WWH, 53.1% reported IPV exposure at baseline. The majority of participants (85.7%) had good perinatal ART adherence. In adjusted models, IPV at baseline was associated with halved odds of good adherence (aOR=0.51, 95%CI=0.20-0.96). IPV was associated with higher adjusted odds of probable depression (aOR=4.64), anxiety (aOR=2.85), and PTSD (aOR=3.42). In SEM, IPV had a direct (standardized coef=-0.22) and indirect effect (coef=-0.05) on ART via common mental disorders. The total effect of IPV on perinatal adherence was of moderate size (coef= -0.27) and the model had good fit (CFI=0.972; TLI=0.969; RMSEA=0.045; SRMR=0.076). Conclusion: IPV was longitudinally associated with perinatal ART non-adherence in part due to its relationship with mental health symptomology. Addressing IPV within clinical care has potential to improve perinatal mental health, maternal HIV outcomes, and HIV-free infant survival.

Intervention with Microfinance for AIDS and Gender Equity (IMAGE): Women's Engagement with the Scaled-up IMAGE Programme and Experience of Intimate Partner Violence in Rural South Africa.

The Intervention with Microfinance for AIDS and Gender Equity (IMAGE) programme has been scaled up to three provinces in South Africa. This paper explores associations between women's engagement in the intervention, intimate partner violence (IPV) and factors associated with IPV and partner abuse. We enrolled women receiving group-based microfinance loans plus gender training into the scaled-up IMAGE cohort study (n = 860). We present cross-sectional analysis on participants' characteristics and intervention engagement and use multivariate logistic regression to explore associations. 17% of women reported lifetime (95% CI 15 to 20%) and 7% past year (95% CI 5 to 9%) IPV, 9% past-year economic (95% CI 7 to 11%) and 11% past-year emotional (95% CI 9 to 14%) abuse. Women under 35 years had higher levels of IPV and emotional abuse. 53% of women attended all the trainings, 83% continuously borrowed and 98% agreed the training had a major impact on their life. Attendance was associated with improved partner relationships (χ2p < 0.001), but not lower IPV risk. Odds of past-year IPV decreased the more types of support (e.g. advice) women received from group members (aOR 0.27, p < 0.001 among those reporting all support versus none or some). A similar pattern was seen for economic, but not emotional, abuse. The scaled-up IMAGE intervention is widely acceptable and may support improvements in partner relationships, but younger women need to be targeted. Group support appears to be a potentially important component of the intervention.

Mechanisms linking intimate partner violence and prevention of mother-to-child transmission of HIV: A qualitative study in South Africa.

Prevention of mother-to-child transmission (PMTCT) can virtually eliminate HIV infection among infants, yet up to one-third of women miss PMTCT steps. Little is known about how partner dynamics such as intimate partner violence (IPV) influence pregnant and postpartum women's adherence to PMTCT. We conducted 32 qualitative interviews with HIV-positive pregnant and postpartum women in Johannesburg who experienced IPV. Trained researchers conducted in-depth interviews over the period of May 2014-Nov 2015 using narrative and social constructionist approaches. Interviews were transcribed verbatim and analyzed thematically and inductively using Dedoose qualitative software. Twenty-six women experienced recent IPV and one-third had poor adherence to PMTCT. Women's experience of partner violence influenced PMTCT behaviors through four pathways. First, fear of partner disclosure led some women to hide their HIV status to avoid a violent reaction. Despite strategic non-disclosure, several maintained good adherence by hiding medication or moving out from their partner's home. Second, IPV caused feelings of depression and anxiety that led to intentionally or accidentally missing medication. Five women stopped treatment altogether, in a type of passive suicidality, hoping to end the distress of IPV. Third, men's controlling behaviors reduced access to friends and family, limiting social support needed for good adherence. Fourth, in a protective pathway, women reported good adherence partly due to their mothering role. The identity around motherhood was used as a coping technique, reminding women that their infant's wellbeing depended on their own health. PMTCT is essential to prevent vertical HIV transmission, but women living with IPV face multiple pathways to non-adherence. Addressing IPV in antenatal care can support the health of women and infants and may enhance PMTCT coverage.

Intimate partner violence during pregnancy and associated mental health symptoms among pregnant women in Tanzania: a cross-sectional study.

OBJECTIVE: Violence against pregnant women is a prevalent issue with severe health implications, especially during pregnancy. This study seeks to determine the prevalence of intimate partner violence against women during pregnancy and its associated mental health symptoms. DESIGN: Cross-sectional survey conducted from December 2011 to April 2012. SETTING: Muhimbili National Hospital antenatal clinic in Dar es Salaam, Tanzania. SAMPLE: 1180 pregnant antenatal care patients. METHODS: Trained interviewers conducted face-to-face standardised interviews with the women in a private room prior to their antenatal care appointment. (PTSD), anxiety and depressive symptoms were assessed through the Conflict Tactics Scale, the John Hopkins Symptom Checklist (25) and the Posttraumatic Diagnostic Scale. MAIN OUTCOME MEASURES: The Conflict Tactics Scale, the John Hopkins Symptom Checklist (25) and the Posttraumatic Diagnostic Scale. RESULTS: Of the 1180 women who were interviewed, 27% reported experiencing both physical and sexual intimate partner violence in the index pregnancy, with 18% reporting physical violence and 20% reporting sexual violence. After adjusting for the sociodemographic characteristics of women, women who experienced physical and/or sexual intimate partner violence during pregnancy were significantly more likely to have moderate PTSD (AOR 2.94, 95% CI 1.71-5.06), anxiety (AOR 3.98, 95% CI 2.85-5.57) and depressive (AOR 3.31, 95% CI 2.39-4.593) symptoms than women who did not report physical and/or sexual intimate partner violence during pregnancy. CONCLUSIONS: About three out of ten women experienced physical or sexual intimate partner violence during pregnancy by an intimate partner, which was significantly associated with poor mental health symptoms. These rates are alarming, and justify training and education of antenatal care providers to raise awareness.

Age at menarche is associated with prediabetes and diabetes in women (aged 32-81 years) from the general population: the KORA F4 Study.

AIMS/HYPOTHESIS: The aim of this study was to examine the association between age at menarche and prediabetes as well as diabetes, considering confounding factors and the possible mediating role of adult obesity. METHODS: This cross-sectional study analysed data on 1,503 women aged 32-81 years from the German population-based KORA (Cooperative Health Research in the Region of Augsburg, South Germany) F4 Study (2006-2008). Data were collected by standardised interviews, physical examinations, and whole blood and serum measurements, including administration of an OGTT in non-diabetic participants. RESULTS: Of the 1,503 women, 226 showed a prediabetic state (impaired fasting glucose and/or impaired glucose tolerance) and 140 persons had diabetes (45 participants with previously undiagnosed diabetes and 95 with known diabetes). In Poisson regression analysis, age at menarche was significantly inversely associated with prediabetes or diabetes after adjustment for year of birth (RR 0.88; 95% CI 0.82, 0.94, p < 0.0001 per additional year of menarche) and after additional adjustment for a number of confounding factors (RR 0.88; 95% CI 0.83, 0.94, p = 0.0001). Further adjustment for current BMI slightly attenuated the association with prediabetes or diabetes (RR 0.89; 95% CI 0.83, 0.95, p = 0.0009), but the association remained clearly significant. CONCLUSIONS/INTERPRETATION: Age at menarche seems to be inversely associated with prediabetes and diabetes independent of confounding factors including current BMI. Women at risk for diabetes might be identified by a history of young age at menarche.

[Pharmacokinetics of theophylline and caffeine in premature infants with apnea (author's transl)]. / Pharmakokinetik von Theophyllin und Coffein bei Frühgeborenen mit Apnoen.

In apneic premature infants treated with theophylline or caffeine the pharmacokinetics of the methylxanthines were investigated. Orally applied caffeine and theophylline were rapidly absorbed reaching peak plasma levels at 1-2 and 1-4 h resp. The plasma concentration of free theophylline was significantly higher (p less than 0.001) in prematures than in adults. In prematures and adults only 5 resp. 8% of caffeine were bound to the plasma proteins. The salivary methylxanthine concentration corresponds to the plasma concentration of the free drugs. The mean plasma half-live of theophylline was 22.3 h, the clearance 28.3 ml/kg/h and the volume of distribution 0.9 l/kg. For caffeine a plasma half-live of 70.6 h, a clearance of 8.6 ml/h/kg and a volume of distribution of 0.84 l/kg was found. A first oral dose of 7-9 mg/kg theophylline or caffeine should be administered to reach rapidly effective plasma concentrations of about 10 micrograms/ml. To maintain a mean plasma concentration of about 10 micrograms/ml, a daily oral maintenance dose of 5-9 mg/kg theophylline or 2 mg/kg caffeine should be given. High concentrations of unchanged caffeine and theophylline were excreted in the urine of premature infants indicating immaturity of the metabolizing hepatic enzymes. In prematures treated with theophylline caffeine was found in plasma as a metabolite of theophylline.
