The purpose of this study was to investigate the correlation between dietary patterns and the risk of sarcopenic obesity (SO) in community-dwelling elderly.
Research Methods & Procedures
SO was defined as the coexistence of sarcopenia and obesity. Participants with low skeletal muscle index (SMI), low muscle strength, or low physical performance were diagnosed with sarcopenia, while obesity was defined as waist circumference (WC) ≥85 cm in males and ≥80 cm in females. The dietary patterns were determined by principal component analysis (PCA). Multinomial logistic regression analysis was used to evaluate the relationship between dietary patterns and SO.
Among 3,795 Chinese participants, 112(3.0%) were diagnosed with SO. After adjusting for confounding variables, lacto-ovo vegetarian dietary pattern was negatively associated with the risk of SO. The odds ratio (OR) for SO was 0.79 [95% confidence interval (CI): 0.65,0.97), P = 0.027] for the lacto-ovo vegetarian dietary pattern, while meat-fish and junk food dietary patterns were not associated with the risk of SO.
It is suggested that the elderly should have a balanced daily diet such as lacto-ovo vegetarian dietary pattern to prevent the occurrence and progression of SO.
