Obesity in Middle Age Increases Risk of Later Heart Failure in Women - Results from the Prospective Population Study of Women and H70 Studies in Gothenburg, Sweden.

• Obesity has been shown to be a risk factor for heart failure, but whether the association varies by age is not understood.To examine the impact of obesity/overweight on the risk of developing heart failure in women of different ages by analysing prospective data from 2 population studies.Data were obtained from the Population Study of Women in Gothenburg and the Gerontological and Geriatric Population Studies concerning Body Mass Index (BMI) collected in 1980 or later. Follow-up ended 2006. Cox proportional hazard methods were used to determine associations between developing HF and BMI in 2574 women, 1243 aged 26-65 and 1331 aged 66-76 at baseline.Women aged 26-65 years at baseline with BMI≥30 had an increased risk of developing heart failure (hazard ratio (HR) 2.61, 95% confidence interval (CI) 1.56-4.35) even when controlling for age, glucose, smoking, alcohol consumption, s-triglycerides, and systolic blood pressure (reference group: women with BMI 18.5-22.4). Obese older women 66-76 years at baseline did not show increased risk of developing HF (HR 0.55, 95% CI 0.23-1.29).Obesity in middle aged women increases their risk of developing heart failure later in life. In contrast, obesity in late life shows no association with heart failure.
