Maternal Characteristics and Incidence of Overweight/Obesity in Children: A 13-Year Follow-up Study in an Eastern Mediterranean Population.

Objectives To investigate clustering of parental sociobehavioral factors and their relationship with the incidence of overweight and obesity in Iranian children. Methods Demographics, body weight, and certain medical characteristics of the parents of 2999 children were used to categorize parents by cluster; children's weights were assessed for each cluster. Specifically, survival analysis and Cox regression models were used to test the effect of parental clustering on the incidence of childhood overweight and obesity. Results Maternal metabolic syndrome, education level, age, body weight status, and paternal age had important roles in distinguishing clusters with low, moderate, and high risk. Crude incidence rates (per 10,000 person-years) of overweight and obesity were 416.8 (95% confidence interval (CI) 388.2-447.5) and 114.7 (95% CI 101.2-129.9), respectively. Children of parents with certain constellations of demographic and medical characteristics were 37.0 and 41.0% more likely to become overweight and obese, respectively. Conclusions for Practice The current study demonstrated the vital role of maternal characteristics in distinguishing familial clusters, which could be used to predict the incidence of overweight and obesity in children.
