Background: Body mass index (BMI) is a commonly used obesity index, exhibiting definite linear relationship with metabolic risk factors in the obese BMI (BMI ≥25 kg/m2) group. However, the relationship is unclear and seomtimes paradoxical in the overweight group (23≤BMI<25 kg/m2). This study aims to assess the association between waist-to-height ratio (WHtR) and metabolic risk factors in this group.
Methods: We analyzed data from a pooled population of 3,925 overweight adults aged 19?74 years (23≤BMI<25 kg/m2) from the Korea National Health and Nutrition Examination Survey, 2010?2012 (KNHANES V). We assessed the association between WHtR and metabolic risk factors with multiple regression analysis, and the relationship between obesity (cutoff WHtR=0.5) and metabolic risk factors with complex samples logistic regression analysis. Adjustments were for age, sex, smoking, alcohol consumption, and exercise.
Results: WHtR was significantly related to metabolic risk factors except for diastolic blood pressure in both genders in multiple regression analysis. In complex samples logistic regression analysis of the group including all participants of KNHANES V, the prevalence of metabolic risk and metabolic syndrome was significantly higher with a WHtR ≥0.5 than in those with a WHtR of <0.5. In the study group, the prevalence of metabolic syndrome was 2.578 times higher (confidence interval 1.961?3.390) in those with WHtR ≥0.5 than in those with a WHtR of <0.5 (P<0.001).
Conclusion: WHtR (cutoff value=0.5) may be useful as a simple and valid obesity index for screening metabolic risk, particularly for those overweighed and are therefore at increased health risks.
