Factor Analysis of Metabolic Syndrome in Aged Population Undergoing Periodical Health Examinations

Background : Metabolic syndrome (MetS) is a common health problem in aged people. The cluster of diseases associated with MetS, namely, heart disease, cerebrovascular disease, diabetes, hypertensive disease and renal disease, had made a death rate of 0.17%, higher than 0.15% attributed to cancers. Aims: To investigate the prevalence, incidence and reversion rate of MetS in Aged population undergoing periodical health examinations, as well as the associated impact factors. Results: The prevalence of MetS was found to be 19.9% among all the subjects studied, to be higher in female (23.1%) than in male (18.3%). The incidence of MetS was 17.6%. In contrast, the reversion rate of MetS was 45.0%. Sex ( p = 0.045) and history of hyperlipidemia ( p = 0.006) were two factors found to be significantly associated with the reversion rate of MetS. Conclusion: Physical examinations may help early detect diseases and revise high risk factors timely. Compared with the ordinary older population, those undergoing periodical health examinations tended to have lower incidence of MetS, better health status and higher disease reversion rate than incidence. To sum up, individualized health education and guidance is an imperative and critical nursing intervention to ensure a healthy state for aged population.
