Persistent Food Insecurity and Overweight/Obesity Risk in Offspring of Individuals With Gestational Diabetes.
Assess how changes in food insecurity in the first 2 years of life are associated with overweight and obesity among children 6-11 years old born to mothers with gestational diabetes mellitus (GDM).
This secondary analysis utilised data from the Study of Women, Infant Feeding and Type 2 Diabetes Mellitus after GDM pregnancy, a prospective cohort of 1033 mother-child dyads. Food insecurity was assessed 6-9 weeks, 1 year and 2 years postpartum. Children were categorized as having persistent food security (food secure all visits), persistent food insecurity (food insecure all visits), or transient food insecurity (experienced both food security and insecurity). Overweight, obesity and severe obesity were classified using height and weight at 6-11 years old. Linear and logistic regressions estimated the relationship between food insecurity groups and BMI percentile, overweight, obesity and severe obesity.
Among 748 youth, 72% had persistent food security, 18% had transient food insecurity and 10% had persistent food insecurity. Compared to those with persistent food security, those with persistent food insecurity had higher odds of overweight (aOR = 2.81, [1.36, 5.80]), obesity (aOR = 2.17, [1.05, 4.47]) and severe obesity (aOR = 2.62, [1.02, 6.74]) (p < 0.05).
Screening and addressing food insecurity during early childhood may help identify children at risk for overweight, obesity and severe obesity among children exposed to GDM.
