In order to assist their community in planning intervention and prevention programs, prevalence rates for diabetes and obesity were examined among the Louisiana Coushatta.
Coushatta individuals participated in a health survey (questionnaires and physical examinations). Those without known diabetes underwent oral glucose tolerance testing and were classified as having normal glucose tolerance (NGT), impaired glucose tolerance (IGT), or diabetes mellitus (DM). Those with known DM had the diagnosis confirmed by history and/or elevated hemoglobin A1c. Waist-to-hip ratio (WHR), body mass index (BMI), and percent body fat (%BF) were determined as measures of central adiposity and obesity. Prevalence rates of diabetes and obesity among those examined were calculated. The prevalence of those with more than one anthropometric index positive for obesity was also determined.
The prevalence of DM was 30% and IGT was 17% among the first 151 Coushatta participants. For males, the prevalence of obesity was 62%, 57%, and 52%, and for females, 59%, 54%, 45%, as determined by the BMI, %BF, and WHR, respectively. Obesity was more prevalent among those with glucose intolerance (IGT + DM) than those with NGT, and those who were obese had the highest prevalence of glucose intolerance. A greater percentage of those with glucose intolerance had more than one positive obesity measure as compared to those with NGT, and those with more than one index consistent with obesity had a greater prevalence of IGT + DM.
Prevalence rates of DM and obesity are high among the Louisiana Coushatta, and obesity is associated with glucose intolerance. Clustering of the three obesity measures occurs in a high percentage of individuals. Data from the current survey are providing information that is being used by the Coushatta community for health planning and development of intervention and prevention programs.
为了帮助其社区规划干预和预防项目，对路易斯安那州库沙塔部落人群的糖尿病和肥胖患病率进行了调查。
库沙塔部落的个体参与了一项健康调查（问卷调查和体格检查）。那些无已知糖尿病的个体接受口服葡萄糖耐量测试，并被分类为具有正常糖耐量（NGT）、糖耐量受损（IGT）或糖尿病（DM）。那些已知患有糖尿病的个体通过病史和/或糖化血红蛋白升高来确诊。测定腰臀比（WHR）、体重指数（BMI）和体脂百分比（%BF）作为中心性肥胖和肥胖的指标。计算所检查人群中糖尿病和肥胖的患病率。还确定了多个肥胖人体测量指标呈阳性的人群的患病率。
在前151名库沙塔部落参与者中，糖尿病患病率为30%，糖耐量受损患病率为17%。根据BMI、%BF和WHR测定，男性肥胖患病率分别为62%、57%和52%，女性分别为59%、54%、45%。糖耐量异常（IGT + DM）人群中的肥胖患病率高于糖耐量正常人群，且肥胖人群中糖耐量异常的患病率最高。与糖耐量正常人群相比，糖耐量异常人群中有更多比例的人有多个肥胖指标呈阳性，且多个指标符合肥胖的人群中IGT + DM的患病率更高。
路易斯安那州库沙塔部落人群中糖尿病和肥胖的患病率很高，且肥胖与糖耐量异常有关。很大比例的个体出现三种肥胖指标聚集的情况。本次调查的数据正在为库沙塔部落社区用于健康规划以及干预和预防项目的制定提供信息。
