Abstract

Background: Metabolic Syndrome (MetS) is a complex disorder unifying dyslipidemia, insulin resistance, and hypertension. MetS has been well known as a primary risk factor for diabetes and cardiovascular disease. The loss of muscle mass and strength with age is also significantly associated with type II diabetes and cardiovascular disease in older adults. Although these two phenomena seem to be associated with each other, little is known concerning the relationship between MetS and body composition status as well as physical function specific to Korean older women, who have a higher incidence of cardiovascular disease and type Ii diabetes and also have lowered physical function. The purpose of this study was to determine whether there is a relationship between Metabolic syndrome and body composition & physical function in older women in Korea.

Method: The overall prevalence of metabolic syndrome in these participants was 42.5%. Systolic(t=2.14, p<.05) and diastolic blood pressure(t=2.85, p<.01) were significantly higher in MetS than Non-Mets. MetS also has higher fat (t=2.14,p<.05), percent fat (t=2.85, p<.01), BMI (t=2.49, p<.05), waist circumference(t=2.73, p<.01) than non-MetS. Different from our expectation, there were no difference in 30-second chair stand, arm curl and sit and reach. However, older women without metabolic syndrome had better balance, agility & dynamic balance, aerobic endurance (p<.05) than women with MetS.

Results: The overall prevalence of metabolic syndrome in these participants was 42.5%. Systolic (t=2.14, p<.05) and diastolic blood pressure(t=2.85, p<.01) were significantly higher in MetS than Non-Mets. MetS also has higher fat (t=2.14,p<.05), percent fat (t=2.85, p<.01), BMI (t=2.49, p<.05), waist circumference(t=2.73, p<.01) than non-MetS. Different from our expectation, there were no difference in any physical function measures (i.e., 30-second chair stand, arm curl, sit and reach, one-leg stand, 244 Time to Up and Go, 2-minute steps) between MetS and non-MetS.In the further analysis by obese category, there were significant differences observed on BMI (z=-3.984, p<.001), body fat (z=-2.37, p<.05) and percent body fat(z=-3.08, p<.01) only in normal weight group. No difference of any above variables between MetS and non-MetS in overweight and obese groups has been observed. In physical function, only char stand in obese group were significantly different between MetS and non-MetS (z=-2.62, p<.01)

Conclusion: In conclusion, metabolic syndrome in older women may worsen physical function. Understanding the current distribution of MetS and its relation with physical function in older adults may help to customize clinical and public health initiatives aimed at reducing disability in older women. Feature of metabolic syndromes were significantly associated metabolic syndrome yet there were not clear relationship between MetS and physical function in older adults. Further investigation is needed to figure out whether MetS affect physical function and disability status in later life.
