Objective. To determine the usefulness of the waist-to-height ratio (WHtR) to estimate trunk-fat deposition in a multi-ethnic population of Japanese and Australian Caucasian adult males (18-40 years of age) living in Australia.

Design. Body composition of 45 Japanese and 42 Australian Caucasian males was measured using dualenergy X-ray absorptiometry (DXA) and relationships between the body composition results and anthropometric indices, including WHtR, body-mass index (BMI), waist circumference (WC) and sum of skinfolds (SSF) were determined.

Results. WHtR was well correlated (r ranged from 0.527 to 0.697 in Japanese, 0.496 to 0.576 in Australians) with trunk fat and percentage body fat (%BF) and less correlated with trunk lean mass compared to BMI and WC (ie, fat-sensitive). Compared to other anthropometric parameters, WHtR was the only index which estimation of both %BF and percentage body fat in the trunk region (%TF) were not affected by ethnicity and age. The study also found that the relationship between WHtR and proportion of trunk fat relative to the total body fat (P(trunk)) was influenced by age and ethnicity. The influence of ethnicity may be associated with a significant (P<0.01) difference in body proportions between Japanese and Australian Caucasian males.

Conclusion. Although further validation is recommended, findings from the current study suggest that WHtR may be useful as an alternative option to identify individuals with excessive trunk-fat deposition and at risk of the metabolic syndrome in a multi-ethnic population.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
