To investigate the association of fresh vegetable consumption with the risk of diabetes in a Chinese population.
Data from 2386 individuals aged 35-74 years who participated in a population-based cross sectional diabetes survey in Qingdao, China were analyzed. Frequency of vegetable intake was obtained using a food frequency questionnaire. Diabetes was defined as self-reported diabetes or undiagnosed diabetes determined by 2-h 75 g oral glucose tolerance test or fasting capillary blood glucose test. Multivariate-adjusted odds ratio (OR) for the presence (vs. the absence) of diabetes in association with the frequency of fresh vegetable intake was estimated using logistic regression analysis.
The OR for the presence of diabetes was 1.17 (95% CI 0.66, 2.05) in men and 0.50 (95% CI 0.33, 0.77) in women who ate fresh vegetables more than 14 times/week as compared with those who ate fresh vegetables less than 7 times/week after adjustment for age, family history of diabetes, BMI, systolic blood pressure, 24-h energy intake, physical activity and smoking and drinking.
Consumption of fresh vegetables was associated with a low risk of having diabetes in women but not in men in this Chinese population.
在中国人群中研究新鲜蔬菜摄入量与糖尿病风险之间的关系。
分析了来自中国青岛一项基于人群的糖尿病横断面调查的 2386 名年龄在 35-74 岁的个体的数据。使用食物频率问卷获得蔬菜摄入量的频率。糖尿病的定义为自我报告的糖尿病或未诊断的糖尿病，通过 2 小时 75 g 口服葡萄糖耐量试验或空腹毛细血管血糖试验确定。使用逻辑回归分析估计与新鲜蔬菜摄入量频率相关的糖尿病存在（与不存在）的多变量调整比值比（OR）。
与每周食用新鲜蔬菜少于 7 次的人相比，每周食用新鲜蔬菜超过 14 次的男性糖尿病存在的 OR 为 1.17（95% CI 0.66，2.05），女性为 0.50（95% CI 0.33，0.77），校正年龄、糖尿病家族史、BMI、收缩压、24 小时能量摄入、体力活动和吸烟饮酒后。
在该中国人群中，女性食用新鲜蔬菜与糖尿病风险低有关，但男性则不然。
