To outline the study design of the Multicultural Community Health Assessment Trial (M-CHAT). The purpose of the study is to compare the relationship between visceral adipose tissue (VAT) and total body fat in men and women of Aboriginal, Chinese, and South Asian origin with a similar group of men and women of European origin.
A total of 200 apparently healthy men and women between the ages of 30 and 65 will be recruited from each of the local Aboriginal, Chinese, and South Asian and European communities. Within each sex/ethnic group, an equal representation of participants will have a body mass index between 18.5 to 24.9, 25 to 29.9 and >30. Each participant will undergo an assessment for VAT, total body fat, metabolic risk factors, physical activity, diet, quality of life, and sociodemographics.
The primary outcome of this study is the relationship between VAT and total body fat in each of the Aboriginal, Chinese, and South Asian cohorts; this relationship will be compared to the European cohort after adjustment for age, sex, socioeconomic status, smoking status, physical activity, diet, and body mass index.
This study will be the first to identify differences in body fat distribution in these populations. We anticipate that in populations of Aboriginal, Chinese, and South Asian origin, a greater proportion of total body fat will be deposited as VAT compared to those of European origin.
概述多元文化社区健康评估试验（M-CHAT）的研究设计。该研究的目的是比较原住民、华裔和南亚裔男性和女性的内脏脂肪组织（VAT）与全身脂肪之间的关系，并与欧洲裔的一组类似男性和女性进行比较。
将从当地原住民、华裔、南亚裔和欧洲裔社区各招募200名年龄在30至65岁之间、表面健康的男性和女性。在每个性别/种族组中，体重指数在18.5至24.9、25至29.9和>30之间的参与者将有同等比例的代表。每位参与者将接受VAT、全身脂肪、代谢风险因素、身体活动、饮食、生活质量和社会人口统计学的评估。
本研究的主要结果是原住民、华裔和南亚裔队列中VAT与全身脂肪之间的关系；在对年龄、性别、社会经济地位、吸烟状况、身体活动、饮食和体重指数进行调整后，将把这种关系与欧洲裔队列进行比较。
本研究将首次确定这些人群体脂分布的差异。我们预计，与欧洲裔人群相比，原住民、华裔和南亚裔人群中，作为VAT沉积的全身脂肪比例会更高。
