Popis: Background: The association between variability in body mass index (BMI) in early adulthood and cardiac structure and function in midlife has not been previously examined. Methods: We examined 2371 Coronary Artery Risk Development in Young Adults (CARDIA) participants who had BMI assessments across 25-years (CARDIA exam year 0 [1985-1986], 2 [1987-1989], 5 [1990-1991], 7 [1992-1993], 10 [1995-1996], 15 [2000-2001], 20 [2005-2006], and 25 [2010-2011]) as well as echocardiography data at the year-25 exam (2010-2011). BMI variability was assessed by standard deviation (SD) across 25 years. Adjusted multivariable linear regression models were used to assess the association between echocardiography variables (dependent variable) and SD of BMI (independent variable). Model 1 was adjusted for standard cardiac risk factors (age, sex, race, education, blood pressure, anti-hypertension medication use, smoking, fasting plasma glucose, alcohol consumption, physical activity, HDL and total cholesterol. Model 2 was additionally adjusted for mean BMI. Results: Among participants included in the analysis, mean [SD] age at the year 25 exam [2010-2011] was 50.4 [3.6] years; 44.5% were men; and 41.3% were black). In model 1, greater SD of BMI was associated with greater left ventricular mass (β 5.18g, p.05 for all). Greater SD of BMI was associated with worse diastolic function (E/é) (β 0.11, p Conclusions: Greater body weight variability in young adulthood was associated with modest unfavorable midlife alterations in diastolic function.
