Background

Diabetes prevalence estimation and reduction of its risk factors remain the major goals of health services. While obesity is the major risk factor for diabetes, body fat distribution may be a better predictor.

Aims

To estimate the prevalence of diabetes in an adult working population in Mexico City, and to evaluate the strength of association with different risk factors.

Methods

A cross-sectional survey was conducted in two city halls of Mexico City. Anthropometrics, blood pressure, physical activity, diet, and biochemical parameters were assessed. Diabetes was defined as a fasting plasma glucose level ≥7.0 mmol/l or referred diabetes. The bioelectrical impedance analysis of body components was performed and weight, soft lean mass, body fat percentage and abdominal fat were obtained. Prevalence with 95% confidence intervals was estimated, as well as odds ratios derived from a logistic regression model.

Results

The prevalence of type 2 diabetes was 11.0% (95% CI 9.6–12.4%). The proportion of individuals with diabetes who were unaware of having the disease was higher in women (42.5 vs. 36.9%), and the degree of metabolic control was better in women (39.1 vs. 25.0%). Age, blood pressure, triglycerides and the percentage of body fat, were major risk factors related to the occurrence of type 2 diabetes. No relation was observed with physical activity and diet.

Conclusions

The prevalence of type 2 diabetes in Mexico continues to be high and obesity measured by body fat percentage seems to be a better predictor of its occurrence than body mass index.

与2型糖尿病的高发生率相关的体脂百分比而不是体重指数。

背景

估计糖尿病患病率并降低其危险因素仍然是卫生服务的主要目标。虽然肥胖是糖尿病的主要危险因素，但体内脂肪分布可能是更好的预测指标。

目的

评估墨西哥城成年人工作人群中的糖尿病患病率，并评估与不同风险因素的关联强度。

方法

在墨西哥城的两个市政厅进行了横断面调查。评估了人体测量学，血压，体力活动，饮食和生化参数。糖尿病被定义为空腹血糖≥7.0mmol / l或被称为糖尿病。进行身体成分的生物电阻抗分析，并获得体重，软瘦体重，体脂百分比和腹脂。估计具有95％置信区间的患病率，以及从逻辑回归模型得出的比值比。

结果

2型糖尿病的患病率为11.0％（95％CI 9.6-12.4％）。女性中不知道患有该疾病的糖尿病患者比例更高（42.5比36.9％），而女性的代谢控制程度更好（39.1比25.0％）。年龄，血压，甘油三酸酯和体内脂肪百分比是与2型糖尿病发生相关的主要危险因素。与体育锻炼和饮食没有关系。

结论

在墨西哥，2型糖尿病的患病率仍然很高，与体质指数相比，用体脂百分比衡量的肥胖似乎更能预测其发生。
