College education protects middle-age caucasian women again...( There are significant racial difference...),Health

Lewis and colleagues examined the interactive effects of race and three levels of education: low, high school or less; moderate, some college; and high, college degree or more, on body mass index (BMI) and changes in BMI. BMI is calculated as weight in kilograms divided by the square of height in meters. Researchers followed 2019 women whose average age was approximately 46 years old from Chicago, Detroit, Boston and Pittsburgh for four years as part of the Study of Women Health Across the Nation (SWAN).

Lewis found there were no differences in BMI in African American and white women with a high school education or less. However, Lewis found that black-white disparities in BMI widen with increasing levels of education.

"We observed significant racial differences in the effects of education on weight for middle-aged women. At all levels of education, African American women were equally heavy, while white women were thinner with increasing baseline educational attainment. These results are consistent with previous studies of young girls, adolescents and adult women. In this respect African American women do not seem to benefit from educational attainment in the same way that white women do."

The authors state that "While overall rates of obesity have increased dramatically in the United States, the prevalence rates of overweight and obesity remain disproportionately higher for African American women than for white women. Although the excess weight observed in African American women has been primarily considered a result of low socioeconomic status (SES), evidence from previous studies suggests that SES may influence overweight and obesity for women of different racial groups."
