Osteosarcopenic obesity and its relationship with dyslipidemia in women from different ethnic groups of China.

Abstract

To explore the prevalence and ethnic differences of osteosarcopenic obesity (OSO) and dyslipidemia and their relationship among Maonan, Mulam, Hmong, and Yao minorities in China. A total of 2315 Maonan, Mulam, Hmong, and Yao women aged 20-95 from Guangxi were included in this study. Questionnaire survey was carried out and their blood lipids were tested. Body compositions were measured by bioelectrical impedance analysis, and T-score was assessed by ultrasonic examination, respectively. Our study showed ethnic-specific prevalence of OSO. In older women, the incidence rates of OSO in Mulam were 4.9, 12.6, and 11.5% in Maonan, Mulam, and Hmong ethnicity, respectively. In younger group, the incidence rates of OSO were 0.4, 0.4, and 0.6%, respectively. However, there is no prevalence of OSO in Yao women in two groups. The prevalence of dyslipidemia in younger women was 22.86, 29.89, 43.35, and 80.00% in group numbering one, two, and three, respectively. In older women, it was 29.13, 39.02, 41.37, and 52.38%, respectively. Based on logistic regression analysis, after controlling for covariates, dyslipidemia in younger group was positively associated with a higher number of adverse body composition, especially for OSO (OR = 12.53, 95%CI 1.34-116.99). Compared with normal women, OSO women in older group were also more likely to have dyslipidemia (OR = 6.75, 95%CI 3.19-14.31). OSO may be a risk factor for dyslipidemia in the ethnic groups. Thus, efforts to promote healthy aging should be focused on preventing obesity and maintaining bone health and muscle mass.
