The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study identified continuous associations between maternal glucose levels during pregnancy at ~28 weeks’ gestation and newborn adiposity. In this issue, Lowe Jr et al, on behalf of the HAPO Follow-up Study Cooperative Research Group (https://doi.org/10.1007/s00125-018-4809-6), examined associations between maternal pregnancy glucose, including levels below those diagnostic of gestational diabetes, and offspring adiposity during early adolescence (mean age 11.4 years). The authors report that maternal fasting glucose and glucose post-load levels at 1 and 2 h were associated with childhood obesity and per cent fat >85th percentile across the maternal glucose continuum, independent of the BMI of the mother. Continuous relationships between maternal glucose levels and child adiposity measures were also observed. The authors conclude that these findings demonstrate that the full range of maternal glucose levels are independently associated with child adiposity, which could have implications for glucose treatment targets in mothers with pre-existing or gestational diabetes, especially those with other risk factors for greater offspring adiposity, including obesity.
