Title: Temporal Patterns of Depressive Symptoms in Tuberculosis Patients: Longitudinal Analysis from the HAALSI Cohort in South Africa
Abstract: Tuberculosis (TB) remains a significant global health issue, with persistent treatment, diagnosis and funding gaps, all of which have been exacerbated by the Covid-19 pandemic. South Africa experienced an estimated 280,000 new TB cases in 2022 alone, with high HIV comorbidity. Depression is highly prevalent among TB patients, significantly impacting their treatment adherence and outcomes. This seminar presents a longitudinal analysis of depressive symptoms using 3 comparison groups defined by TB diagnosis status, using data from the Health and Aging in Africa: Longitudinal Study of an INDEPTH Community (HAALSI) cohort. Conducted in the rural Agincourt sub-district of Mpumalanga, South Africa, in a population of older adults, HAALSI offers the unique opportunity to study the long term interaction of mental illness and Tuberculosis, in a high prevalence setting.
Key Findings:
TB diagnosis is associated with persistently higher depressive symptoms, which remain significantly elevated for 4 to 7 years after the first TB diagnosis.
The analysis is replicated using a nationally representative dataset, the National Income Dynamics Study (NIDS), and similar patterns are found. Comparing the HAALSI and NIDS data is useful as a preliminary validation exercise of these and other existing research findings across different populations in South Africa.
