Outline of Final Research Achievements

A relationship between hypertension and intra-abdominal fat (IAF) in young adulthood is not clear. In a cross-sectional study, intra-abdominal fat area was measured using a dual bioelectrical impedance analysis instrument in 697 university students (20.3±0.7 years, 425 men). Blood pressure and anthropometric factors were measured. Lifestyle variables including smoking, drinking, physical activity, and eating behavior were assessed with questionnaire. High blood pressure risk (SBP>-130mm Hg and/or DBP>-85mm Hg) with increasing IAF area was evaluated. Participants were divided into 5 groups according to their intra-abdominal fat area (-24.9, 25.0-49.9, 50-74.9, 75-99.9, and 100- cm2). As compared with the values of the smallest IAF area group, the lifestyle-adjusted odds ratios (ORs) were elevated (OR 1.31, 95% CI 0.66-2.80; OR 3.38, 95% CI 1.60-7.57; OR 7.71, 95% CI 2.75-22.22; OR 18.74, 95% CI 3.93-105.64, respectively). The risk increase was observed only in men.
