Abstract
The study aimed to investigate prevalence, awareness, treatment and control of type 2 diabetes mellitus (T2DM), and to explore potential risk factors in rural areas of China. A total of 16413 individuals aged 18–74 years in rural districts were recruited from the Rural Diabetes, Obesity and Lifestyle (RuralDiab) study for the epidemiological research. Meanwhile, a meta-analysis including 7 published studies was conducted to validate the result of the cross-sectional study. The rates of crude and age-standardized prevalence, awareness, treatment and control of T2DM were 12.19%, 67.00%, 62.35%, 22.20% and 6.98%, 60.11%, 54.85%, 18.77%, respectively. The prevalence, awareness, treatment and control of T2DM displayed increased trends with age (Ptrend < 0.01) and were strongly associated with education, drinking, more vegetable and fruit intake, physical activity, family history of diabetes, body mass index (BMI). The results of this meta-analysis showed that the pooled prevalence, awareness, treatment and control of T2DM in China countryside were 7.3% (5.3–9.4%), 57.3% (36.9–77.6%), 48.4% (32.4–64.5%) and 21.0% (9.9–32.1%), respectively. The prevalence of T2DM was high with inadequate awareness, treatment and control of T2DM in China rural areas. Healthy lifestyles should be advocated to reduce prevalence and improve awareness, treatment, and control of T2DM in Chinese rural residents.
Highlights
In the countryside, the increase of incidence rate is faster while the awareness, treatment and control of diabetes are lower in rural districts than those in cities[16,17]
Among subjects with type 2 diabetes mellitus (T2DM), 1340 people were aware of their condition, 1247 taking medicine, and only 444 had their fasting plasma glucose (FPG) level controlled
The present study is the first one attempting to overall appraise the prevalence, awareness, treatment and control of T2DM in Chinese rural population using the large sample epidemiological research and meta-analysis. The results of this epidemiological study indicated that the crude prevalence, awareness, treatment and control of T2DM were 12.19%, 67.00%, 62.35% and 22.20%, respectively, which were slightly higher than the results of this meta-analysis
Summary
In the countryside, the increase of incidence rate is faster while the awareness, treatment and control of diabetes are lower in rural districts than those in cities[16,17]. Previous studies have focused on prevalence, awareness, treatment, control and risk factors assessment in China[17,18], the results were inconsistent due to the difference in living regions, economy, culture, occupation, diet and life style. What’s more, the research special in synthesizing the prevalence, awareness, treatment and control of T2DM by combining rural study and meta-analysis has not yet been reported. The meta-analysis only selected articles conducted in the Chinese countryside containing prevalence, awareness, treatment and control of T2DM. The present study synthesizing prevalence, awareness, treatment and control of T2DM was conducted by combining epidemiological research and meta-analysis in China countryside areas
