Prevalence of asthma among children in India: A systematic review and meta-analysis

Abstract

There is a lack of national-level estimates on the magnitude of asthma among children in India. Hence, we undertook a systematic review and meta-analysis to estimate the prevalence of asthma among children in India. We searched PubMed, Embase, Cochrane Library, and Google Scholar, and included cross-sectional studies reporting data on the prevalence of asthma among children in India. A random-effects model was used to estimate the pooled prevalence of asthma. In the 33 selected studies (pooled sample of 167,626 children), the estimated prevalence of asthma was 7.9% (95% confidence interval: 6.3-9.6%), I2 = 99.1% (P < 0.001). The prevalence was higher among boys and in urban areas. Appropriate training and resources should be made available at the primary healthcare level for early detection and management of asthma in children. A nationwide population-based survey is indicated to provide reliable estimates of the burden of asthma.
