RESUMO
Background: Unhealthy alcohol use is widespread in South Africa and has been linked to tuberculosis (TB) disease and poor treatment outcomes. This study used qualitative methods to explore the relationship between TB and alcohol use during TB treatment. Methods: Focus groups (FGs) were conducted with 34 participants who had previous or current drugsusceptible TB and self-reported current alcohol use. Eight interviews were conducted with healthcare workers who provide TB services in Worcester, South Africa. Results: In this rural setting, heavy episodic drinking is normalized and perceived to be related to TB transmission and decreased adherence to TB medication. Both healthcare workers and FG participants recommended the introduction of universal screening, brief interventions, and referral to specialized care for unhealthy alcohol use. However, participants also discussed barriers to the provision of these services, such as limited awareness of the link between alcohol and TB. Healthcare workers also specified resource constraints while FG participants or patients mentioned widespread stigma towards people with alcohol concerns. Both FG participants and health providers would benefit from education on the relationship between TB and unhealthy alcohol use as well and had specific recommendations about interventions for alcohol use reduction. Healthcare workers also suggested that community health worker-delivered interventions could support access to and engagement in both TB and alcohol-related services. Conclusion: Findings support strengthening accessible, specialized services for the identification and provision of interventions and psychosocial services for unhealthy alcohol use among those with TB.
RESUMO
BACKGROUND: Alcohol is a teratogen; its consumption during pregnancy can lead to negative birth outcomes, collectively referred to as fetal alcohol spectrum disorders. Neurodevelopmental delays in higher-order cognitive functions that affect development of executive functions are a common feature. Studies on executive function in children have focused on children diagnosed with fetal alcohol spectrum disorder, and there is a lack of information on the impact on children not diagnosed with fetal alcohol spectrum disorder but who had been exposed to alcohol. OBJECTIVE: The aim of this study was to compare the development of executive function in children between 4 and 6 years of age with and without prenatal exposure to alcohol. METHODS: Children both exposed and not exposed to alcohol were recruited as part of a feasibility RCT evaluating a computer-based cognitive training program for improving executive function development. The study was conducted in a low-socioeconomic status community in South Africa with a high prevalence of fetal alcohol spectrum disorder. Neurodevelopment was assessed in participating children; NEPSY-II standardized scores for executive function domains were compared using a multivariate analysis of variance with group membership as the predictor variable. RESULTS: No significant differences in executive functions assessments (P=.39) were found between children in the alcohol-exposed group (n=76) and those in the nonexposed group (n=40). Both groups showed moderate to severe delays in domains. In all but one subtest, the average score for both groups was below the 25th percentile of expected norms. CONCLUSIONS: We expected that alcohol exposure would have a measurable impact on executive function development. The lack of differences highlights the prevalence of developmental delays in low-socioeconomic status communities in South Africa and suggests that children are exposed to various threats to cognitive development.
