| 摘要: | Background: Metabolic syndrome (MS), a cluster of metabolically related cardiovascular risk factors, is associated with increased risk of morbidity and mortality for both diseases cardiovascular events and diabetes mellitus. Socioeconomic status (SES) may influence the risk of the metabolic syndrome. The aim of this study is to determine relationship between SES and prevalence of the MS, its components in representative sample of middle aged and elder adults in Mongolia.
Methods: We are analyzing a total of 2280 individuals, ages 40 to 90 years who participated in the nationwide STEP survey for screening chronic disease among Mongolian adults which was conducted in 2009. Education, occupation, and monthly income of individuals are using as socioeconomic indicators. MS is defined according to the Joint Interim Statement criteria, by the presence of at least three of the following characteristics: waist circumference > 90cm men and >80cm women, blood pressure ≥135/85 mmHg, fasting plasma glucose ≥5.6mmol/l, triglyceride ≥1.7mmol/l, HDL-C <1.0mmol/l men and <1.3mmol/l women.
Results: The prevalence of the MS among in this population was a 36.8%, more likely to have in women 43.2% than men 26.1% respectively. Of the individual MS components, central obesity is highest prevalence (59.7%) and second highest prevalence is hypertension (50.2%). Almost over half of participants (69.3%) had a two or more components. Compared to males, females presented a significantly higher prevalence of abdominal obesity (72.0% vs 36%), reduced HDL-C (41.6% vs 19.4%) and a lower prevalence of triglyceride (37.2% vs 43.1%). Of the individual components central obesity and high blood pressure are significantly (p<0.05) associated with education in males. As well as education and income are associated with elevated plasma glucose in females (p<0.05). In total sample highest odds ratio for MS is more likely to have in high SES people. Gender specifically in men the odds favoring MS significantly increased with income and decreased with social class as described by current occupation. In women, middle income level is significantly associated with higher odds ratio for the MS. In particularly odds ratios for MS in women increased linearly as education were increased.
Conclusion: The prevalence of MS is higher among adults in Mongolian. Higher SES associated with higher risk of MS in Mongolian adults, especially in women. Education and occupation were positively associated with individual components of MS. The survey results revealed that MS is distributed in Mongolia, and this can be interpreted that cardiovascular disease and diabetes are expected to increase in the future. Multidimensional effort by individuals, community, and national health program can be achieved to reduce the risk of the MS. |
