Prevalence of high risk adults of type 2 diabetes in Zhejiang

Abstract

Objective To investigate the prevalence characteristics for high risk adults of type 2 diabetes in Zhejiang. Methods From June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7 571 families from fifteen counties in Zhejiang by a four stage stratified-random sampling method. A self-designed questionnaire was completed to collect information on demographic characteristics, risk factors, and physical activity. At the same time, physical examinations including measurements of height, weight, blood pressure, and blood lipid levels were carried out. The high-risk population was determined according to the 2017 edition of China′s Guidelines for the Prevention and Treatment of Type 2 Diabetes. Results Finally, 17 437 people completed all the investigation projects. Among them, 14 455 people were at high risk of type 2 diabetes [aged (49.3+15.1) years, 6 902 men (47.75%) and 7 553 women (52.25%)]. The crude prevalence rate of high risk type 2 diabetes was 82.90% (standardized rate: 79.26%). A significantly higher prevalence rate of high risk type 2 diabetes was associated with the age group of 45 to 60 years (83.47%), men (84.49%), class 1 rural area (84.59%), primary school education level (87.04%), marital status (84.40%), and average annual family income less than 10 000 yuan (all P<0.05). Among the eight high risk factors, the detection rate of ≥40 years old was the highest (78.12%) and the detection rate of history of cardiovascular disease was the lowest (1.54%). The detection rates of overweight/obesity/central obesity, dyslipidemia, hypertension, sedentary lifestyle, pre-diabetes, and family history of type 2 diabetes were 42.86%, 31.28%, 29.98%, 29.18%, 7.28%, and 3.81%, respectively. High risk of type 2 diabetes was dominated by 1 high-risk factor (31.75%) or 2 high-risk factors (31.39%) or 3 high-risk factors (22.13%). The adults with 4 high-risk factors (11.01%) and 5 or more high-risk factors (3.71%) were less in number. The detection rates of all the risk factors and aggregation distribution of various risk factors were significantly different between different genders, age groups, regions and educational levels, marital status, and family per capita annual income. Conclusion The epidemic level of high-risk type 2 diabetes in Zhejiang province is relatively high, and health management of high risk of type 2 diabetes in community should be actively taken as early as possible according to the population distribution characteristics.
