Abstract 14919: Short Adult Stature is an Independent Predictor of Cardiovascular Disease Risk Factors and Subclinical Vascular Changes in a Larger Population Based Sample
Background: Studies have demonstrated strong association between short adult stature (a marker of adverse nutritional and sanitary environment in early years) and cardiovascular disease (CVD) mortality. The reasons for this association are not understood although early childhood epigenetic programming has been invoked. Here we analyze the association between adult height and CVD risk factors and subclinical vascular changes in a Southeast Asian population that has experienced rapid income growth with increasing prevalence of CVD over the last decade.
Methods: In a population-based study of 8,080 South Indians (mean age 42 years; 58% women), assessments included blood pressure, socioeconomic (SE) and physical activity (PA) status, triglycerides (TG), total cholesterol (TC), glucose tolerance test, carotid intimal medial thickness (IMT), arterial stiffness by carotid-femoral pulse wave velocity (PWV) and endothelial function by brachial artery flow mediated dilatation (FMD).
Results: The prevalence of CVD risk factors and values of subclinical vascular parameters by height quartile is shown in the Table. After adjustments for age, weight, SE and PA status and smoking, in comparison to highest height quartile the odds ratio (95% CI) for diabetes, hypertension and elevated levels of TG (≥ 150 mg/dl) and TC (≥ 200 mg/dl) in the lowest height quartile was 1.3 (0.97, 1.6), 1.7 (1.4 - 2.2), 1.4 (1.1, 1.8), 1.5 (1.2, 1.9) in women and 2.01 (1.5, 2.7), 1.9 (1.5, 2.5), 1.5 (1.2, 1.9), 1.9 (1.5, 2.5) in men, respectively. In multi-linear regression models that included both genders, height was independently correlated with FMD (β= 0.31, p <0.01), IMT (β= 0.06, p <0.01) and PWV (β= -0.06, p <0.01).
Conclusion: Adult Stature is an independent predictor of CVD risk factors and subclinical vascular changes. Adverse environment in early years may be one of the contributing factors to the increasing prevalence of CVD in the Southeast Asian adult population.
