To investigate the association of the dietary pattern with the presence of newly diagnosed glucose tolerance abnormalities among Chinese adults.
A total of 20,210 adults aged 45-69 years from the 2002 China National Nutrition and Health Survey were included. Information on dietary intake was collected using a validated food frequency questionnaire. Factor analysis and cluster analysis were used to identify the food factors and dietary pattern clusters.
Four dietary pattern clusters were identified ("Green Water," "Yellow Earth," "Western Adopter," and "New Affluence"). The prevalence of glucose tolerance abnormalities ranged from 3.9% in the Green Water to 8.0% in the New Affluence. After adjustment for area, age, sex, current smoking, and physical activity, subjects in the Yellow Earth cluster (prevalence ratio 1.22 [95% CI 1.04-1.43]) and New Affluence cluster (2.05 [1.76-2.37]) had significantly higher prevalence rates compared with those for the Green Water cluster. After further adjustment for BMI and waist-to-height ratio, the elevated risk in the New Affluence remained statistically significant.
Dietary patterns and food factors are associated with the presence of glucose tolerance abnormalities in China, even independent of obesity. A New Affluence diet is an important modifiable risk factor, which needs attention from the prevention point of view.
探讨中国成年人饮食模式与新诊断葡萄糖耐量异常之间的关联。
共纳入 20210 名年龄在 45-69 岁的 2002 年中国营养与健康调查的成年人。采用经过验证的食物频率问卷收集饮食摄入信息。采用因子分析和聚类分析来识别食物因素和饮食模式聚类。
确定了四个饮食模式聚类(“绿水”、“黄土”、“西方采用者”和“新富裕”)。葡萄糖耐量异常的患病率从“绿水”的 3.9%到“新富裕”的 8.0%不等。在调整了地区、年龄、性别、当前吸烟和体力活动后,与“绿水”聚类相比,“黄土”聚类(患病率比 1.22[95%CI 1.04-1.43])和“新富裕”聚类(2.05[1.76-2.37])的患病率明显更高。进一步调整 BMI 和腰围身高比后,“新富裕”的风险仍然具有统计学意义。
饮食模式和食物因素与中国葡萄糖耐量异常的发生有关,即使与肥胖无关。“新富裕”饮食是一个重要的可改变风险因素,需要从预防的角度引起重视。
