Abstract

Objective: To test the hypothesis that maternal gestational diabetes increases cardiovascular risk markers in Indian children.

Research design and methods: Anthropometry, blood pressure, and glucose/insulin concentrations were measured in 514 children at 5 and 9.5 years of age (35 offspring of diabetic mothers [ODMs], 39 offspring of diabetic fathers [ODFs]). Children of nondiabetic parents were control subjects.

Results: At age 9.5 years, female ODMs had larger skinfolds (P < 0.001), higher glucose (30 min) and insulin concentrations, and higher homeostasis model assessment (HOMA) of insulin resistance and systolic blood pressure (P < 0.05) than control subjects. Male ODMs had higher HOMA (P < 0.01). Associations were stronger than at age 5 years. Female ODFs had larger skinfolds and male ODFs had higher HOMA (P < 0.05) than control subjects; associations were weaker than for ODMs. Associations between outcomes in control subjects and parental BMI, glucose, and insulin concentrations were similar for mothers and fathers.

Conclusions: The intrauterine environment experienced by ODMs increases diabetes and cardiovascular risk over genetic factors; the effects strengthen during childhood.
