N2 - We examined the relations of central adiposity with left ventricular (LV) diastolic dysfunction in men and women who participated in the Baltimore Longitudinal Study of Aging, a prospective community-based study of older persons. The sample for this cross-sectional analysis included 399 women and 370 men. Central adiposity was estimated using the waist circumference (WC) and global adiposity using the body mass index (BMI). Using data from a comprehensive echocardiographic study that included tissue Doppler imaging, diastolic function was graded according to 3 parameters (E/A ratio, E/Em ratio, and left atrial volume index). In the logistic regression models adjusted for age, gender, cardiovascular risk factors, and hemodynamic parameters, WC and BMI were both independently associated with LV diastolic dysfunction. However, when both WC and BMI were in the same model, only WC remained significantly associated with LV diastolic dysfunction (odds ratio 1.04, 95% confidence interval 1.01 to 1.08, p = 0.02). In the gender-stratified analyses, WC was significantly associated with LV diastolic dysfunctionindependently of BMIin women (odds ratio 1.08, 95% confidence interval 1.04 to 1.14, p <0.001) but not in men (odds ratio 1.00, 95% confidence interval 0.95 to 1.05, p = 0.91). Additional adjustment for LV mass index failed to modify these relations. In conclusion, the adverse effect of central adiposity on LV diastolic function was independent of general adiposity and more pronounced among women. The effect of visceral adiposity on LV diastolic dysfunction would benefit from confirmation in longitudinal studies.
