ABSTRACT

Objective To investigate the prevalence and risk factors of diabetes and prediabetes in Jingyuan County in Ningxia. Methods A cross-sectional survey including 10 639 participants (18-88 years of age) with a multistage sampling was conducted in Jingyuan County between January, 2014 and April, 2015. Questionnaires, physical examinations, and laboratory tests were included in the survey. Results Among all the subjects, 10 491 participants (men 4 826, women 5 665) with complete data were included in the analysis. The standardized prevalence of diabetes and prediabetes was 4.2% (men 3.9%, women 4.5%) and 8.8% (men 7.6%, women 10.3%), respectively, in which the standardized prevalence of diabetes was higher in Hui (4.5%) than that in Han (3.5%) (P<0.05). Logistic regression analyses showed that age, family history of diabetes, overweight/obesity, hypertriglyceridemia and hypertension were positively associated with prediabetes and diabetes with the odds ratios being 1.60 and 2.14 (age, P<0.001), 1.40 and 3.32 (family history, P< 0.05), 1.47 and 1.57 (overweight/obesity, P< 0.001), 1.88 and 2.55 (hypertriglyceridemia, P<0.001), 1.44 and 1.89 (hypertension, P<0.001), respectively. Conclusions The prevalence of diabetes was relatively low in the rural area in Ningxia. However, it is still essential to take active interventions in people at high risk of diabetes in order to prevent the incident diabetes.
