RESUMO
Objective To investigate the incidence and distribution of over-weight and obesity and the relationship between the body mass index (BMI) and the chronic diseases in the elderly of community in Beijing. Methods The medical check-up data of 1513 elderly inhabitants randomly selected from the 134 communities in Beijing were analyzed. Results The proportions of old people with overweight and obesity were 48.9% and 12.8% respectively, and 36.5% of them were having normal body weight. The incidence of hypertension, coronary heart disease (CHD), diabetes mellitus (DM), hyperlipidemia, hyperuricemia and fatty liver were significantly higher in the over-weight and obese people than that of people with normal BMI. Multiple logistic regression analysis showed that BMI was positively correlated highly with hyperlipidemia and fatty liver (P
RESUMO
Objective To explore the prevalence and clinical features of hyperuricemia in elderly people and to analyze the influencing factors of hyperuricemia in elderly people. Methods Serum uric acid (SUA) levels in 1500 elderly people were examined by the uricase-peroxidase enzymatic method .Clinical parameters of hyperuricemia group and normal SUA group were comparatively analyzed. Logistic regression was used to analyze the influencing factors of SUA in elderly people. Results In 264 out of 1500 (17.6%) the SUA level were increased. The ratio of male to female in the hyperuricemia group was 256:8. The proportion of the patients with increased SUA levels, mean level of SUA, serum urea nitrogen, serum creatinine and serum triglyceride were all increased with age. As compared with the normal SUA group, the hyperuricemia group were more prone to have adiposis hepatica (P
RESUMO
Objective To investigate the prevalence and distribution of metabolic syndrome in the middle-aged and elderly community population of Beijing. Methods The medical check-up data in 2335 middle-aged and elderly persons, who were sampled randomly from the 136 communities in Beijing, were acquired and analyzed. Results The incidences of the middle-aged and elderly people with metabolic syndrome (MS), obesity, essential hypertension, glucose metabolic disorder, hyper triglyceridemia 28.7%, 40.2%, 56.7%, 64.1%, and 38%, respectively. In the groups of old and very old persons, the respective incidence of MS, blood sugar disorder, and essential hypertension was higher, and obesity and hyper glyceridemia were significantly lower than that of middle-aged group. Conclusion The incidence of MS is very high in the middle aged and elderly community population of Beijing. The incidence of MS and its components in the middle aged people are different from that of elderly population.
