Longitudinal assessment of changes in hair cortisol levels and associations with violence, poor mental health and harmful substance use among female sex workers in Nairobi, Kenya
Female sex workers (FSWs) in sub-Saharan Africa commonly experience violence, mental health problems, and harmful substance use. Stressful life events can harm the functioning of the hypothalamic-pituitary-adrenal (HPA) axis, serving as a pathway to increased poor health, including HIV susceptibility through cortisol levels. In this paper, we examine changes in hair cortisol concentration (HCC) levels and associations with experiences of violence…
Effect of a brief psychological intervention for common mental disorders on HIV viral suppression
Background For people living with co-morbid HIV and common mental disorders (CMD), it is not known whether a brief psychological intervention for CMD can improve HIV viral suppression. Methods We conducted a prospective cohort study in eight primary care clinics in Harare, Zimbabwe, enrolling adults with co-morbid HIV and CMD. Six clinics provided the Friendship Bench (FB), a brief psychological intervention for CMD based on problem-solving thera…
Methodological issues of retrospective surveys for measuring mortality of highly clustered diseases
BACKGROUND: There is a lack of empirical data on design effects (DEFF) for mortality rate for highly clustered data such as with Ebola virus disease (EVD), along with a lack of documentation of methodological limitations and operational utility of mortality estimated from cluster-sampled studies when the DEFF is high. OBJECTIVES: The objectives of this paper are to report EVD mortality rate and DEFF estimates, and discuss the methodological limit…
Epidemiology of alcohol use and alcohol use disorders among people living with HIV on antiretroviral therapy in Northwest Tanzania
Alcohol use disorders (AUD) among people living with HIV (PLHIV) are associated with poor health outcomes. This cross-sectional study examined current alcohol use and AUD among 300 PLHIV on ART at four HIV care centres in Northwest Tanzania. Participants' data were collected using questionnaires. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT). Logistic regression was used to examine associations between each outc…

The impact of common mental disorders among caregivers living with HIV on child cognitive development in Zimbabwe
This paper aimed to assess the impact of maternal common mental disorders (CMD) among caregivers living with HIV on the cognitive functioning of their child. Data were collected at baseline and 12 months follow-up from mother–child dyads recruited as part of an ongoing trial in Zimbabwe. Symptoms of CMD were assessed using the Shona Symptom Questionnaire. Mixed-effects linear regression was used to assess child cognitive scores at follow-up (usin…
Context of Violence in Adolescence Cohort (CoVAC) study
This study is a long-term follow up of participants in the Good Schools Study (NCT01678846, clinicaltrials.gov). This protocol is for cohort follow-up only; we have a separate protocol paper describing an evaluation of the long-term effects of the Good School Toolkit (In preparation)
Promoting school climate and health outcomes with the Seher multi-component secondary school intervention in Bihar, India
Postpartum maternal mental health is associated with cognitive development of HIV-exposed infants in Zimbabwe
This study examines the cognitive profiles of infants born to HIV positive mothers in Zimbabwe. Caregivers with HIV exposed infants delivered in 30 clinics in two areas of Zimbabwe were recruited to the study. Of the 574 study participants, 562 caregiver-infant dyads with a biological HIV +ve mother and infant aged 0-24 months were interviewed. All infants were tested by a trained administrator for cognitive development on the Mullen Scales of Ea…
The Healthy Activity Program (HAP), a lay counsellor-delivered brief psychological treatment for severe depression, in primary care in India
BACKGROUND: Although structured psychological treatments are recommended as first-line interventions for depression, only a small fraction of people globally receive these treatments because of poor access in routine primary care. We assessed the effectiveness and cost-effectiveness of a brief psychological treatment (Healthy Activity Program [HAP]) for delivery by lay counsellors to patients with moderately severe to severe depression in primary…
The development and pilot testing of a multicomponent health promotion intervention (Seher) for secondary schools in Bihar, India
BACKGROUND: Schools can play an important role in health promotion by improving students' health literacy, attitudes, health-related behaviours, social connection and self-efficacy. These interventions can be particularly valuable in low- and middle-income countries with low health literacy and high burden of disease. However, the existing literature provides poor guidance for the implementation of school-based interventions in low-resource setti…
Experiences of stigma and discrimination faced by family caregivers of people with schizophrenia in India
Stigma associated with schizophrenia significantly affects family caregivers, yet few studies have examined the nature and determinants of family stigma and its relationship to their knowledge about the condition. This paper describes the experiences and determinants of stigma reported by the primary caregivers of people living with schizophrenia (PLS) in India. The study used mixed methods and was nested in a randomised controlled trial of commu…
Effect of a Primary Care–Based Psychological Intervention on Symptoms of Common Mental Disorders in Zimbabwe
Importance: Depression and anxiety are common mental disorders globally but are rarely recognized or treated in low-income settings. Task-shifting of mental health care to lay health workers (LHWs) might decrease the treatment gap. Objective: To evaluate the effectiveness of a culturally adapted psychological intervention for common mental disorders delivered by LHWs in primary care. Design, Setting, and Participants: Cluster randomized clinical …
Intimate partner violence as seen in post-conflict eastern Uganda
BACKGROUND: Conflict and post-conflict communities in sub-Saharan Africa have a high under recognised problem of intimate partner violence (IPV). Part of the reason for this has been the limited data on IPV from conflict affected sub-Saharan Africa. This paper reports on the prevalence, risk factors and mental health consequences of IPV victimisation in both gender as seen in post-conflict eastern Uganda. METHODS: A cross-sectional survey was car…

Condom use among female sex workers in Uganda
Consistent condom use can prevent HIV infection, yet levels of condom use are low in many settings. This paper examines determinants of inconsistent condom use among 905 women enrolled in a high-risk cohort in Kampala, Uganda, who reported sexual intercourse with paying clients in the last month. Among these, 40% participants reported using condoms inconsistently with paying clients in the past month. The most common reason for inconsistent condo…
Effectiveness of an intervention led by lay health counsellors for depressive and anxiety disorders in primary care in Goa, India (Manas)
A qualitative study of participant adherence in a randomized controlled trial of herpes suppressive therapy for HIV prevention in Tanzania
Poor participant adherence to treatment may contribute to lack of impact in some biomedical HIV prevention trials. This qualitative study explored adherence in a randomized controlled trial of herpes suppressive therapy to reduce HIV acquisition and infectivity among 1305 Tanzanian women. The trial found participants completed 72% of visits on treatment; 52-56% of women on treatment had > or = 90% adherence by pill count estimate; and between six…
