Maternal Gestational Diabetes and Early Childhood Obesity: A Retrospective Cohort Study.

Background

Recently, childhood obesity has become one of the most serious public health problems in the world. Gestational diabetes mellitus (GDM) is considered a risk factor for childhood overweight and obesity. The study aimed at investigating the relationship between maternal GDM and childhood obesity in children aged from 1 to 3 years.

Methods

In this retrospective cohort study, 237 GDM and 296 non-GDM mothers and their offspring who were followed up by Family Medicine Clinics in Rize province of Turkey were assessed. World Health Organization (WHO) criteria were used for the diagnosis of maternal GDM. Crude and adjusted logistic regression models were calculated for the association of gestational diabetes and childhood overweight/obesity. Gender and age-specific percentile tables were used for the categorization of BMI.

Results

Statistical analysis carried out with adjustment for potential confounders (mother's age, educational status, smoking status, BMI, gestational weight gain, children's gender, and gestational birth weight) provided results with an odds ratio of 2.99; 95% CI 1.14-7.94 and 7.77; 95% CI 1.92-31.37 for the impact of gestational diabetes on childhood overweight and obesity at 2 and 3 years of age, respectively.

Conclusions

This study found evidence for maternal GDM to cause the risk of early childhood obesity. Therefore, proper intervention strategies are required for this high-risk population.
