Effect of pesticide exposure on stunting incidence: a systematic review and meta-analysis   (2,247 times)
Sani Rachman Soleman, Yaltafit Abror Jeem, Muhammad Fathi Banna Al Faruqi, Mahdea Kasyiva, Vita Widyasari, Kuswati Kuswati, Nur Aini Djunet, Muflihah Rizkawati, Ety Sari Handayani
Clin Exp Pediatr. 2024;67(10):510-518.   Published online September 24, 2024
This review aimed to determine whether pesticide exposure is associated with stunting in children. The 13 included studies agree that pesticide exposure is not correlated with stunting incidence regardless of substance type (organophosphate and pyrethroid). Heterogeneity appeared with age covariate as potential confounding. The evidence of this study is challeng-ing, as the adverse effects of pesticides grossly occurred. The protection of children is warranted for preventing future neurodevelopment issues.
