RESUMEN
OBJECTIVE: To assess whether offspring of women following bariatric surgery as well as offspring of obese women are at an increased risk for long-term pediatric endocrine morbidity. SETTING: This study was conducted at the university hospital. METHODS: A population-based cohort study compared the incidence of long-term (up to the age of 18 years) occurrence of endocrine morbidity between offspring of mothers following bariatric surgery and obese mothers, as compared with parturients without obesity and without prior bariatric surgery. RESULTS: During the study period 220,563 newborns met the inclusion criteria; 1001 were delivered by patients following bariatric surgery, 2275 were delivered by obese women and 217,287 were delivered by normal weight women without prior bariatric surgery. Long-term endocrine morbidity was more common in the bariatric group (2.3%) and the obesity group (1.5%) as compared with the comparison group (0.5%; P < 0.001). Specifically, pediatric obesity was significantly more common in children of mothers following bariatric surgery (1.8%) and of mothers with obesity (1.2%) as compared with the comparison group (0.2%; P < 0.001). Children born to women following bariatric surgery as well as obese women had higher cumulative incidence of pediatric endocrine morbidity (Log rank, P < 0.001). The results remained significant when controlling for maternal factors, adjusted HR 6.25, 95% CI 4.10-9.50; P < 0.001 for women following bariatric surgery and aHR 2.40 95% CI 1.69-3.40; P < 0.001 for obese women. CONCLUSION: Offspring of women following bariatric surgery as well as those of obese women are at an increased risk for long-term pediatric endocrine morbidity.
