American Heart Association reports Stressful Events can increase Women’s Odds of ObesityAmerican Heart Association Meeting Report
![]() Women who reported four or more negative events in the last five years, such as unemployed though wanting work, had increased odds of obesity. “Little is known about how negative and traumatic life events affect obesity in women. We know that stress affects behavior, including whether people under- or overeat, as well as neuro-hormonal activity by in part increasing cortisol production, which is related to weight gain,” said study senior author Michelle A. Albert, M.D., M.P.H., professor of medicine, cardiology, and founding director of the Center for the Study of Adversity and Cardiovascular Disease, at University of California, San Francisco. Obesity, a preventable risk factor for cardiovascular and other diseases, impacts more than one-third of U.S. adults. According to the American Heart Association, nearly 70 percent of American adults are either overweight or obese. Women tend to live longer than men, putting especially obese, aging women at greater risk for disease, said study author Eva M. Durazo, Ph.D., a post-doctoral scholar at the NURTURE Center, Division of Cardiology, UCSF said. The researchers studied the relationship between major life events and obesity in a group of 21,904 middle-aged and older women, focusing on women with the highest obesity prevalence. They defined obesity as having a body mass index (BMI) of 30 kg/m2 or higher. And, they measured the impacts of two types of stress: traumatic events, which could occur anytime in a woman’s life and includes such things as death of a child or being a victim of a serious physical attack, as well as negative life events that had occurred in the previous five years of a woman’s life. Negative events included wanting employment but being unemployed for longer than three months or being burglarized. They found:
“Our findings suggest that psychological stress in the form of negative and traumatic life events might represent an important risk factor for weight changes and, therefore, we should consider including assessment and treatment of psychosocial stress in approaches to weight management,” Albert said. Because the study looks at the association between stressful events and obesity in a snapshot of time, future studies should look at the relationship longitudinally, following people for weight gain over time after life events have occurred, according to Albert.
