Frequency and correlates of anxiety and mood disorders among TB- and HIV-infected Zambians.

Abstract: We determined the frequency and correlates of current common mental disorders (CMDs) in a consecutive series of 649 adult patients with human immunodeficiency virus (HIV), tuberculosis (TB) or both receiving treatment at 16 primary health care centres across Zambia. Data on socio-demographic variables, clinical disease features, anxiety and mood disorders were collected. The frequency of any anxiety disorder (AD) was 30.8% and major depressive disorder (MDD) 11.3%. Although differences by disease group did not reach statistical significance, rates of suicidality (34.8%) and panic disorder (4.1%) were highest for the TB–HIV group (n = 269), while rates of generalised AD (13.3%), obsessive compulsive disorder (7.6%), posttraumatic stress disorder (7.4%) and any AD (37.8%) were highest for the HIV group (n = 149). Female gender (p = 0.004) predicted any current AD as well as current suicidality (p = 0.009), while lower education status (p < 0.001) predicted current MDD.

Mitigating the impact of COVID-19 on tuberculosis and HIV services: A cross-sectional survey of 669 health professionals in 64 low and middle-income countries.

Abstract: OBJECTIVE: The experiences of frontline healthcare professionals are essential in identifying strategies to mitigate the disruption to healthcare services caused by the COVID-19 pandemic. METHODS: We conducted a cross-sectional study of TB and HIV professionals in low and middle-income countries (LMIC). Between May 12 and August 6, 2020, we collected qualitative and quantitative data using an online survey in 11 languages. We used descriptive statistics and thematic analysis to analyse responses. FINDINGS: 669 respondents from 64 countries completed the survey. Over 40% stated that it was either impossible or much harder for TB and HIV patients to reach healthcare facilities since COVID-19. The most common barriers reported to affect patients were: fear of getting infected with SARS-CoV-2, transport disruptions and movement restrictions. 37% and 28% of responses about TB and HIV stated that healthcare provider access to facilities was also severely impacted. Strategies to address reduced transport needs and costs-including proactive coordination between the health and transport sector and cards that facilitate lower cost or easier travel-were presented in qualitative responses. Access to non-medical support for patients, such as food supplementation or counselling, was severely disrupted according to 36% and 31% of HIV and TB respondents respectively; qualitative data suggested that the need for such services was exacerbated. CONCLUSION: Patients and healthcare providers across numerous LMIC faced substantial challenges in accessing healthcare facilities, and non-medical support for patients was particularly impacted. Synthesising recommendations of frontline professionals should be prioritised for informing policymakers and healthcare service delivery organisations.

Why teach sexuality education in school? Teacher discretion in implementing comprehensive sexuality education in rural Zambia.

Abstract: Reproductive health problems such as HIV, unwanted pregnancy and unsafe abortion among adolescents are closely linked to insufficient knowledge about sexuality and reproduction and lack of access to contraceptives. Supported by international agencies, Zambia has introduced an ambitious nation-wide program for comprehensive sexuality education (CSE) to be implemented into ordinary school activities by teachers. The curriculum is firmly based in a discourse of sexual and reproductive rights, not commonly found in the public debate on sexuality in Zambia. This paper explores how teachers perceive the curriculum and practice discretion when implementing the CSE in mid-level schools in Nyimba district in Zambia. Using a case study design, data were collected through in-depth interviews with 18 teachers and analyzed thematically drawing upon theories of discretion and policy implementation. Individual teachers make decisions on their own regarding what and when to teach CSE. This discretion implies holding back information from the learners, teaching abstinence as the only way of preventing pregnancy or cancelling sexuality education sessions altogether. Teachers’ choices about the CSE program were linked to lack of guidance on teaching of the curriculum, especially with regards to how to integrate sexuality education into existing subjects. Limited prioritization of CSE in the educational sector was observed. The incompatibility of CSE with local norms and understandings about adolescent sexuality combined with teacher-parent role dilemmas emerged as problematic in implementing the policy. Limited ownership of the new curriculum further undermined teachers’ motivation to actively include CSE in daily teaching activities. Use of discretion has resulted in arbitrary teaching thus affecting the acquisition of comprehensive sexual and reproductive health knowledge among learners. The CSE had limited legitimacy in the community and was met with resistance from teachers tasked with its’ implementation. In order to enhance ownership to the CSE program, local concerns about the contents of the curriculum and the parent-teacher role dilemma must be taken into consideration. Not addressing these challenges may undermine the policy’s intention of increasing knowledge about sexuality and reproduction and empowering adolescents to access contraceptive services and avoid unwanted pregnancies.

Growth effects of exclusive breastfeeding promotion by peer counsellors in sub-Saharan Africa: the cluster-randomised PROMISE EBF trial

Abstract: In this multi-country cluster-randomized behavioural intervention trial promoting exclusive breastfeeding (EBF) in Africa, we compared growth of infants up to 6 months of age living in communities where peer counsellors promoted EBF with growth in those infants living in control communities. A total of 82 clusters in Burkina Faso, Uganda and South Africa were randomised to either the intervention or the control arm. Feeding data and anthropometric measurements were collected at visits scheduled 3, 6, 12 and 24 weeks post-partum. We calculated weight-for-length (WLZ), length-for-age (LAZ) and weight-for-age (WAZ) z-scores. Country specific adjusted Least Squares Means with 95% confidence intervals (CI) based on a longitudinal analysis are reported. Prevalence ratios (PR) for the association between peer counselling for EBF and wasting (WLZ < −2), stunting (LAZ < −2) and underweight (WAZ < −2) were calculated at each data collection point. The study included a total of 2,579 children. Adjusting for socio-economic status, the mean WLZ at 24 weeks were in Burkina Faso −0.20 (95% CI −0.39 to −0.01) and in Uganda −0.23 (95% CI −0.43 to −0.03) lower in the intervention than in the control arm. In South Africa the mean WLZ at 24 weeks was 0.23 (95% CI 0.03 to 0.43) greater in the intervention than in the control arm. Differences in LAZ between the study arms were small and not statistically significant. In Uganda, infants in the intervention arm were more likely to be wasted compared to those in the control arm at 24 weeks (PR 2.36; 95% CI 1.11 to 5.00). Differences in wasting in South Africa and Burkina Faso and stunting and underweight in all three countries were small and not significantly different. There were small differences in mean anthropometric indicators between the intervention and control arms in the study, but in Uganda and Burkina Faso, a tendency to slightly lower ponderal growth (weight-for-length z-scores) was found in the intervention arms.
