Obesity problems may skip a generation, Edinburgh University study finds

Health problems linked to obesity, like heart disease and diabetes, could skip a generation, a new study suggests. Edinburgh experts found the offspring of obese mothers may be spared health problems linked to obesity, while their own children then inherit them.
They found obese mothers can make an impact on the birth weight and diabetes risk of grandchildren, despite it being absent in their own children. Experts said rates of obesity are at an all-time high.
Among the associated health problems are breast and colon cancer and stroke. Moderate obesity is a Body Mass Index (BMI) between 30 and 34.9. The study, carried out in mice, could help inform health policy on obesity.
Scientists studied moderately obese female mice fed on a diet high in fat and sugar before and during pregnancy. The mice were found to pass on the risks of obesity to the second generation of offspring, while virtually no ill effects were seen in the first generation.
Reasons why the first generation is apparently protected are not fully understood. Researchers suggest reasons could include differences in maternal weight gain during pregnancy or specific food eaten during pregnancy.
