The study investigated the relationship between maternal weight and child respiratory problems through a literature review of 15 research articles. The results demonstrated that high prepregnancy weight, pregnancy weight, and weight gain during pregnancy are positively associated with poor child respiratory outcomes like wheezing, asthma, and bronchitis. Maternal overweight or obesity during pregnancy, whether before or during pregnancy, was linked to increased risk of poor respiratory outcomes in offspring. Further research is needed to better understand this relationship and inform recommendations for pregnant women.
