Parental obesity

Maternal obesity refers to obesity (often including being overweight) of a woman during pregnancy. Parental obesity refers to obesity of either parent during pregnancy.

Maternal obesity significantly affects maternal metabolism and offspring development. It disrupts insulin resistance, glucose homeostasis, fat oxidation, and amino acid synthesis, contributing to adverse outcomes. Lifestyle modification is an effective strategy to improve maternal metabolism and prevent complications.

Obesity is defined as having a Body Mass Index (BMI) of 30 or greater. A 5-foot-5-inch tall woman would be considered obese if she weighs 180 pounds or more and a 5-foot-8-inch tall woman would be considered obese if she weighs 200 pounds or more. About one third of women of the reproductive ages are overweight with a BMI greater than or equal to twenty-five.
