Correlation between sarcopenic obesity and dyslipidemia in the young and middle aged adults / 中华健康管理学杂志

ABSTRACT

Objective To explore the relationship between lipids profile and body composition in the young and middle?aged adults. Method The relationship between body composition and lipids profile was examined in 642 adults (21-60 years, 178 male, 464 female). According to the result of body composition assessment, they were assigned to three groups Normal (N, n=272), Obesity (O, n=245), Sarcopenic Obesity (SO, n=125). The lipids profile among three groups and its related factors were analyzed. Results In groups N, O and SO, the levels of total cholesterol (TC), triglycerides (TG), low density lipoprotein?cholesterol (LDL?C) increased gradually (P<0.01), and the high density lipoprotein?cholesterol (HDL?C) level decreased gradually (P<0.01). In a multiple logistic regression analysis, the odds ratio for high levels of TC, TG, LDL?C and low level of HDL?C risk increased gradually in groups N, O and SO [compared to group N, the odds ratio of the four kinds of dyslipidemia in group O were 2.617 (1.117-6.132), 3.549 (1.481-8.503), 4.618 (1.288-16.564), 1.222 (0.529-2.822), respectively, and in group SO were 5.915 (2.512-13.926), 10.430 (4.400-24.722), 9.522 (2.637-34.388) , 4.253 (1.957-9.242) , respectively]. After adjusting for age, sex, waist?to?hip ratio and visceral fat area, the odds ratio for high level of TG risk still increased gradually in group N, O and SO [compared to group N, the odds ratio of group O was 3.565 (1.319-9.632), and of group SO was 8.173 (2.685-24.881)]. Moreover, the odds ratio for high TC and low HDL?C levels of group SO were higher than those of group N [compared to group N, the odds ratio in group SO were 5.658 (1.871-17.111), 6.823 (2.119-21.969) respectively]. With stepwise multivariate logistic regression analysis, for male, the related factors for high levels of TC, TG and low level of HDL?C were high percentage of body fat;sarcopenia, sarcopenia obesity;sarcopenia, respectively. For female, the related factors for high levels of TC, TG and LDL?C were sarcopenia, aging;high percrntage of body fat, aging;sarcopenia, aging, respectively. Conclusion SO was the main risk factor for dyslipidemia in young and middle?aged adults, even more severe than obesity alone and sarcopenia was the risk factor of high TG, low HDL?C levels for male;and the risk factor of high TC, high LDL?C levels for female.
