Description
Kyung Eun Lee and co-authors study body weight before pregnancy and a low-fluid condition in this 2026 paper. Too little fluid around the baby, called oligohydramnios, can signal trouble late in pregnancy. Obesity before pregnancy is a known risk for many birth problems. Its link to low fluid was unclear, and past work used body mass alone. The team analyzed more than seven hundred and sixty thousand women who gave birth over nine years. All had a health exam within two years before conceiving.
Women were sorted into four types by weight and waist size. That split separates general obesity from belly obesity. Models then weighed the odds of low fluid for each type. Other pre-pregnancy traits were taken into account. The design tests whether waist size adds risk beyond body mass. Results can shape counseling before pregnancy begins.
