Prevalence and risk factors of abnormal glucose metabolism in adults with hypertension in Zhengzhou / 中华健康管理学杂志

ABSTRACT

Objective This study aims to analyze the prevalence, distribution, and risk factors of abnormal glucose metabolism in urban and rural adult hypertension patients in Zhengzhou. Methods The study was conducted on permanent residents aged 18 years and over (with at least 6 months of residence) in urban and rural areas of Zhengzhou. The survey subjects were chosen by the multi‐stage sampling method. Basic information regarding the height, weight, waist circumference, and blood pressure of 6 798 people who met the standards of admission and discharge were obtained through an on‐site questionnaire survey and physical examination. Blood samples were collected and blood glucose and lipid levels were detected. Results There were 1 985 patients with hypertension, with a prevalence rate of 29.20% and the standardized prevalence rate was 26.53%. Blood samples were collected from 1 936 hypertensive patients (55.8±13.6 years), of whom 903 were male (46.64%) and 1 033 female (53.36%). Among 1 050 patients (54.24%) with abnormal glucose metabolism, the impaired fasting glucose rate was 4.44%, the decreased glucose tolerance rate was 22.21%, and the diabetes rate was 27.56%. Blood samples were collected from 4 748 non‐hypertensive patients and 1 123 patients (23.65%) with abnormal glucose metabolism. The prevalence of abnormal glucose metabolism in hypertensive patients was significantly higher than that in non‐hypertensive patients, and the difference was statistically significant (χ2=586.264, P<0.001). The prevalence rate of abnormal glucose metabolism in hypertensive patients was higher in females, 58.57%, than in males, 49.28% (χ2=16.743, P<0.001). Urban patients showed a higher abnormal glucose metabolism, 57.68%, than rural patients did, 51.67% (χ2=6.984, P<0.001), and the prevalence of abnormal glucose metabolism in hypertensive patients showed a significant upward trend with an increase in age. Patients with central obesity, abnormal blood lipids, family diabetes history, non‐smokers, and non‐drinkers showed a higher prevalence of abnormal glucose metabolism, and the differences were statistically significant (P<0.05). The prevalence of abnormal glucose metabolism increased with age and body mass index, and decreased with increase in education level, with differences being statistically significant (P<0.001). Multivariate logistic regression analysis showed that age, obesity, centripetal obesity, dyslipidemia, and family history of diabetes were the main risk factors for abnormal glucose metabolism in patients with hypertension. Conclusions There is a relatively high prevalence of abnormal glucose metabolism in hypertension patients among the urban and rural residents of Zhengzhou. In the management of hypertension, the detection and intervention for reducing abnormal glucose metabolism should be strengthened and related risk factors must be prevented. The age for health management objectives among hypertension and diabetes patients should be further reduced.
