title: [Waist:height ratio as a predictor of risk of hypertension in young adults: is it better indicator that waist circumference].
abstract: The objective was to determine the association between values of waist circumference (WC) and waist: height ratio (W/H) with blood pressure (BP) and to estimate which of these indicators present the best association with BP in a young adult population of a semi-rural area of Chile. We performed a cross sectional study in 998 people between 22 and 28 years, born in the Limache Hospital, V Region of the country who were surveyed for socioeconomic and family background, BP and anthropometric measurements were also taken during 2000 and 2003. Linear regression model was apply between control variables and BP, then models between WC and W/H and BP were built adjusting by control variables. The mean of BP was 114.6/72.5 mmHg (+/- 13.5/8.8), WC 83.9 cm (+/- 11.3), W/H 0.52 (+/- 0.07). Age, being male, weight, height and alcohol consumption increased the BP (p < 0.05), scholarity instead decreased it (p < 0.05). A direct association was observed between WC and BP (beta = 0.7 for SBP and 0.33 for DBP) and between W/H and BP (beta = 32.75 for SBP and 23.90 for DBP) (p < 0.01). These association decreases but remain significant after adjustement. There was a similar association between WC with BP compared with W/H (R2 0.20 and 0.37 for SBP; 0.20 and 0.36 for DBP respectively). In our population WC and W/H were significantly associated with BP, with a similar force between them.
