[Study on the incidence and influencing factors of prediabetes in Chinese adults].

To explore the incidence and influencing factors of prediabetes in adults in China. Ten provinces (cities) were selected from the surveillance survey of chronic diseases and their risk factors in China in 2010; two monitoring sites were selected from each province (city) as follow-up spots, and a follow-up survey was conducted from 2016 to 2017. An unconditional logistic regression model was used to analyze the influencing factors of prediabetes. A total of 5 578 participants were included in this study. During the follow-up period, 612 patients (268 males and 344 females) developed impaired glucose tolerone (IGT), with a total follow-up of 37 364.82 person-years, and the incidence of IGT was 16.4/1 000 person-years. Impaired fasting glucose (IFG) occurred in 290 patients (128 males and 162 females) with a total follow-up of 39 731.31 person-years, and the incidence of IFG was 7.3/1 000 person-years. The multivariate unconditional logistic regression model included age, urban and rural areas, family history of diabetes, BMI, central obesity, dyslipidemia, hypertension, and physical activity, and the results showed that age (≥50 years old: =1.60, 95%: 1.32-1.95), urban residents (=1.41, 95%: 1.16-1.71), obesity (=1.56, 95%: 1.12-2.19), dyslipidemia (=1.52, 95%: 1.25-1.83), hypertension (=1.32, 95%: 1.07-1.61) and physical inactivity (=1.25, 95%: 1.04-1.50) increase the risk of IGT. Age (≥50 years old: =1.31, 95%: 1.01-1.70), family history of diabetes (=1.71, 95%: 1.13-2.60), overweight (=1.41, 95%: 1.04-1.92), obesity (=2.09, 95%: 1.38-3.17) and hypertension (=1.53, 95%: 1.18-2.00) increase the risk of IFG. The incidence of IGT is higher than the IFG. People aged 50 and above, overweight and obese people, hypertension patients, dyslipidemia patients, people with insufficient physical activity, and family history of diabetes are prone to prediabetic events.
