Objectives: Sarcopenia is one of the most representative factors of senescence, and nutritional status is known to affect sarcopenia. This study was performed to analyze the relationships between energy and protein intake and sarcopenia.
Methods: The study subjects were 3,236 individuals aged ≥ 65 that participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2008 ~ 2011. General characteristics and anthropometric and 24-hour dietary recall data were analyzed. Sarcopenia was diagnosed using a formula based on appendicular skeletal muscle mass (ASM) and body weight. Logistic regression was performed to determine relationships between sarcopenia risk and energy and protein intakes.
Results: For energy intake, the odds ratio (OR) of sarcopenia in women was significantly higher those with the lowest intake [OR = 1.680, 95% confidence interval (CI) = 1.213-2.326] than those with the highest intake (P for trend = 0.001). Regarding protein intake per kg of body weight, the odds ratio of sarcopenia was significantly higher for those that consumed < 0.8 g/kg of protein daily than those that consumed > 1.2g/kg for men (OR = 2.459, 95% CI = 1.481-4.085) and women (OR = 2.178, 95% CI = 1.423-3.334).
Conclusions: This study shows a link between sarcopenia and energy and protein intake levels and suggests that energy and protein consumption be promoted among older adults to prevent sarcopenia.
