RESUMEN
BACKGROUND: Type 2 diabetes is regarded as one of the major public health problems worldwide. We aim to investigate the prevalence, treatment, and control rate in the Chinese urban population aged 65 years or older and also identified associated risk factors. METHODS: One hundred twenty-four thousand seven participants aged 65 years old and older were recruited from January 2018 through December 2018 at local community health service centers in Shenzhen. Fasting plasma glucose, as well as other biochemical indicators, were measured by standard methods. The analysis of multivariate logistic regression was applied to assess associated risk factors of type 2 diabetes. RESULTS: Approximately 22.5% of elderly urban Chinese residents had diabetes. Among people with diabetes, 54.8% received medical treatment. Only 34.4% of those who were treated had their glycemic controlled. The prevalence of T2D increased with increasing age before 80 years old, male, inadequate active physical activity, drinking, previous history of CVD, higher BMI, central obesity, and hypertension. CONCLUSIONS: Our findings suggested that attention should be paid to the prevention and control of T2D in Chinese urban elderly population. The health policy department should develop effective strategies aimed at improving health care management of T2D in elderly adults.

BACKGROUND: There may be a beneficial effect on lipid levels in Shenzhen in recent years. In this study, we aimed to examine trends in serum lipids in population in Shenzhen between 2009 and 2015. METHODS: We enrolled 2210 adults aged 18-70 years from two independent cross-sectional studies conducted in 2009 and 2015. Blood lipid profiles, such as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), were measured. Chi-square test, t-test and multivariate logistic regression analysis were applied for data analysis. RESULTS: From 2009 to 2015, mean LDL-C declined from 3.05 ± 0.76 mmol/L in 2009 to 2.27 ± 0.75 mmol/L in 2015 (P < 0.001). Similarly, a significant 7.09% decrease in the prevalence of high LDL-C was observed over the same period (P < 0.001). There was an increasing trend in the prevalence of low HDL-C among adults in Shenzhen (P < 0.001). A no-significant increase in prevalence of dyslipidemia was also observed over this 6-year interval (P = 0.139). The prevalence of dyslipidemia was closely related with increasing age, male gender, current smoker, diabetes, obesity and overweight. CONCLUSION: This study shows a favourable downward trend in LDL-C concentration in Shenzhen. However, more intense strategies are needed to control dyslipidemia.

Objective: Few studies reported the association between serum uric acid and the prevalence of metabolic syndrome in China's coastal residents. We aimed to examine the association between serum uric acid and the prevalence of metabolic syndrome as well as its components in adults and elderly from Shenzhen (a China's coastal city). Methods: We conducted a survey in a community-based household population in Shenzhen, collecting data about 4049 participants aged 20-69 years. Based on the data, we determined the prevalence of metabolic syndrome in adults and elderly with different serum uric acid concentrations. Results: According to the revised National Cholesterol Education Program Adult Treatment Panel III, the prevalence of the metabolic syndrome in the surveyed participants was 24.69% [95% confidence interval (CI): 23.4%-26.0%]. The prevalence of metabolic syndrome in participants with serum uric acid levels <4, 4-4.9, 5-5.9, 6-6.9, 7-7.9, and ≥8 mg/dL is 10.12% (95% CI: 8.2%-12.0%), 17.92% (95% CI: 15.8%-20.1%), 31.05% (95% CI: 28.1%-34.0%), 39.47% (95% CI: 35.4%-43.8%), 49.39% (95% CI: 43.1%-55.7%), and 52.57% (95% CI: 42.5%-62.5%), respectively. Multivariable logistic regression analysis showed that participants with higher serum uric acid levels were at a higher risk of high triglycerides, low high-density lipoprotein, central obesity, high blood pressure, or high fasting glucose (P < 0.001). Conclusions: Serum uric acid levels were closely associated with metabolic syndrome and its components in Chinese coastal population.

OBJECTIVES: Few studies reported the clustering of cardiovascular disease (CVD) biological risk factors among older adults. The objective of this study was to characterise the clustering of CVD biological risk factors among adults aged 65 or older in Shenzhen city, China. DESIGN: Cross-sectional study. SETTING: General communities in Shenzhen, Guangdong, China. PARTICIPANTS: A representative sample of 5635 participants aged 65 or older participated in the survey with a response rate of 93.6%. MAIN OUTCOME MEASURES: Individual CVD biological risk factors (overweight/obesity, central obesity, hypertension, dyslipidaemia and diabetes) and their clustering. RESULTS: The prevalence of overweight, obesity, central obesity, hypertension, dyslipidaemia and diabetes in this study was 37.4%, 10.8%, 37.0%, 51.9%, 40.2% and 18.0%, respectively. The mean count of CVD biological risk factors per participant was 1.95. The 86.0% of the participants presented at least one CVD biological risk factor and 33.8% of the participants presented clustering of CVD biological risk factors, that is, presenting three or more CVD biological risk factors, as defined in this study. Multivariable logistic regression analysis showed that gender, age, and drinking and smoking status were significantly associated with clustering of CVD biological risk factors (P<0.05). Women, the older and alcohol drinkers were more likely to have clustering of CVD biological risk factors. CONCLUSIONS: The prevalence of CVD biological risk factors is fairly high in the older adults with a tendency of clustering in Shenzhen. The findings highlight the need for integrated management of CVD biological risk factors among older adults.

BACKGROUND: Dyslipidemia is one of the most important independent modifiable risk factors for cardiovascular diseases. The objective of this study was to determine the prevalence and risk factors for dyslipidemia in Shenzhen, a special economic zone and large metropolitan area neighboring Hong Kong. METHODS: A cross-sectional survey of 1,995 adults with a mean age of 46.56 years was conducted between February and July 2011 using a multistage stratified cluster random sampling. All the subjects were administered questionnaires regarding socio-demographic characteristics and other possible factors associated with the prevalence of dyslipidemia. Fasting venous blood samples were collected to assess the lipid profile. Weight, height, waist circumference, and blood pressure were measured. RESULTS: The mean concentrations of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were 5.11 ± 1.15 mmol/L, 1.59 ± 1.47 mmol/L, 1.42 ± 0.33 mmol/L, and 3.22 ± 0.84 mmol/L, respectively. High values of TC, TG, low HDL-C, and high LDL-C were obtained in 14.49%, 16.14%, 8.82%, and 12.13 % of the 1,995 participants, respectively. The prevalence of dyslipidemia was 34.64%, among which 25.04% of subjects were aware. Presence of dyslipidemia was significantly associated with increasing age, smoking status, hypertension, diabetes, and body mass index. CONCLUSIONS: High prevalence of dyslipidemia with relative low awareness in Shenzhen was found. A comprehensive strategy is required for the prevention, screening, treatment, and control of dyslipidemia in Shenzhen.
