Anxiety, stress, and quality of life in patients with tuberculosis: A systematic review and meta-analysis

Anxiety symptoms when coexisting with tuberculosis (TB), can have deleterious effects on treatment continuation that could contribute to the development of treatment resistance in TB. It is essential to understand the prevalence of anxiety in TB to develop clinical recommendations for its management. The primary objective of our review was to estimate the pooled prevalence of anxiety in TB patients along with the estimation of stress and quality of life in such patients. The relevant literature search on observational studies published in the English language till the year 2020 was carried out. A total of 8086 participants from 29 studies were included, of which 24 were cross-sectional studies and the remaining were case–control, and cohort studies. The estimated pooled prevalence of anxiety, comorbid depression, stress, and poor quality of life in TB patients was 32.54% [24.95, 41.18], 32.87% [25.79, 40.82], 52.68% [48.60, 56.72], and 79.51% [45.67, 94.72] respectively. When comparing the prevalence of anxiety across World Health Organization (WHO) regions, there was a statistically significant difference, with the African Region (AFR) having the highest prevalence i.e. 37.87% [29.59, 46.92], and the Western Pacific Region (WPR) having the lowest prevalence i.e. 15.83 % [12.72, 19.53]. The higher prevalence of anxiety in TB in the AFR and South-East Asian Region (SEAR) suggests a strong correlation with the developing status of these regions which calls for efforts to identify and treat the risk factors common to both anxiety and TB.
