Relationships Between Serum Lipoprotein (a) And Sarcopenia In Elderly

Background: Examine the association of serum Lp(a) with sarcopenia in Chinese elderly.Methods: We conducted this study using 2015–2020 data from hospitalized Chinese people 60 years old and older. Total body fat percentage and appendicular skeletal muscle mass were assessed with a dual-energy X-ray absorptiometry scan. We classified the participants into four sarcopenia/obesity groups based on both total body fat percentage and appendicular skeletal muscle mass.Results: The analysis included data of 528 participants. the LP(a) level of sarcopenia was significantly higher than no sarcopenia, compared with obese or no obese groups. Furthermore, In the sarcopenic obesity group, the LP(a) level was highest. Correlation analysis showed that ASM/height2 was negatively correlated with LP(a). Logistic regression analysis showed that sarcopenia was positively associated with LP(a).Conclusions: Our study shows that sarcopenia appeared to be significantly associated with Lp(a) no matter the subjects had obesity or not.
