Outline of Final Research Achievements

The object of this study was to investigate the association between normal weight central obesity and life-style factors in Japanese middle-aged adults. The prevalence of normal weight central obesity classified using BMI and WHtR was 15.6 % in men and 30.2 % in women. Normal weight with central obesity was associated with cardiovascular disease risks such as hypertension, dyslipidemia, and diabetes, compared with normal weight without central obesity, regardless of sex. These results persisted even after adjusted for age, weight, smoking status, alcohol intakes, and physical activity. Moreover, we found that normal weight central obesity was associated with hyperuricemia in men and women, regardless of alcohol consumption.

Academic Significance and Societal Importance of the Research Achievements

職域における大規模健康診断データの解析結果から、日本の成人における隠れ腹部肥満と生活習慣との関連について性別、年代別に新知見が得られることが予想される。腹囲とBMIの組み合わせによる判定は、今後の健康診断基準の検討のための基礎資料として有意義な情報となり、労働者における隠れ腹部肥満に関連する疾病の予防に資することが期待される。
