Comparison of the key modifiable factors in the first 1000 days predicting subsequent overweight and obesity in pre-school children in Tehran: A case control study.

Background & objective The identification of pediatric obesity predictors in the early stages of life is warranted, as it can influence the development of effective strategies to prevent metabolic disorders. Methods In this case-control study, we assessed nine risk factors for pediatric obesity, namely a birth weight >4000 grams, an exclusive breastfeeding period Results In the randomly selected 509 preschool children from Tehran, children exposed to gestational diabetes had the maximum predicted probability of obesity [4.36 (1.94-9.80) %] among the analyzed risk factors. %]. The introduction of solid food at 1.8 times [1.15-2.94], and > 1.5 times (1.015-2.43) respectively. There was no association between the paternal body mass index, the exclusive breastfeeding time, and the risk of pediatric obesity. Conclusion Among early risk factors, probably gestational diabetes can be considered as the most important predictor for the risk of pediatric obesity.
