Systematic review confirms link between pesticide exposure and respiratory issues in children
According to a systematic review and meta-analysis, exposure to pesticides significantly increases the risk of asthma, wheezing, and lower respiratory tract infections in children.
The review included 38 articles, encompassing a sample size of 118,303 children under 18 years of age. Data extraction and quality assessment were performed by 4 independent reviewers.
The meta-analysis found that pesticide exposure significantly increased the risk of asthma in children by 24% (OR = 1.24, 95% CI: 1.14-1.35), despite extreme heterogeneity (I² = 81%, P < 0.001). In addition, the odds of developing wheezing were elevated by 34% (OR = 1.34, 95% CI: 1.14-1.57) with high heterogeneity (I² = 79%, P < 0.001). Pesticide exposure was associated with a 79% higher risk of lower respiratory tract infections (OR = 1.79, 95% CI: 1.45-2.21), with low but nonsignificant heterogeneity (I² = 30%, P = 0.18).
The researchers concluded that these findings “contribute to a better understanding of the estimate of the effect of pesticide exposure on respiratory health in children and inform evidence-based preventive strategies and public health interventions.”
