Lean Body Mass as a Predictive Value of Hypertension in Young Adults, in Ankara, Turkey
Background: The aim of this study was to assess the predictive capacity of body composition estimated by bioelectrical impedance analysis (BIA) to identify abnormal blood pressure in physical education and sport teaching students in the city of Ankara.
Methods: Data for this cross-sectional study were obtained in the city of Ankara in 2014. A total of 133 students aged 20-35 yr participated in this study. Anthropometric measurements were measured. Body composition was assessed by BIA. Physical activity level (PAL) and usual dietary intake were assessed. Pre-hypertension and hypertension were defined, respectively, as BP ≥120 and/or 80, and ≥140 and /or 90 mmHg.
Results: More overweight students showed abnormal BP especially SBP (P=0.005 and 0.002, respectively). Age adjusted regression showed significant association between arm circumference (β= 0.176, P 0.044), mid arm muscle circumference (MAMC) (β= 0.235, P 0.007), lean body mass (LBM) (β= 0.238, P 0.006), basal metabolism rate (BMR) (β= 0.219, P 0.012) and SBP and, also, MAMC (β= 0.201, P 0.022), LBM (β= 0.203, P 0.021), BMR (β= 0.189, P 0.030) and DBP. Fat intake was associated with DBP (β= 0.14, P =0.040). Multivariate regression models adjusted for age, BMI, WC and fat intake/kg body weight showed positive association of SBP with MAMC, BMR and LBM (P<0.05).
Conclusion: The relationship between blood pressure and body composition in young adults may be associated to LBM and MAMC. LBM or MAMC in this population may be indirect indicators of heart muscle mass and heart pumping power.
