Introduction: The aim of this study was to determine the association between protein intake and physical activity with sarcopenia of the elderly. Older people are a vulnerable group and are easily reflected in their nutritional status, most do not cover their nutritional requirements and are physically inactive. A protein intake <1.2 g/kg/day and a low level of physical activity (<3.5 MET) are factors associated with sarcopenia.
Material and Methods: Observational, analytical, prospective, case-control study. Sampling was done for convenience in patients over 60 years of service outpatient Medical Center Adolfo Lopez Mateos, Toluca, Mexico. Questionnaires were used to determine protein intake and physical activity, and diagnostic tests for Sarcopenia (percentage of muscle mass, strength and speed Manual operation). 115 subjects were enrolled but 110 (55 cases and 55 controls) were included.
Results: The odds ratio (OR) of the variables was obtained, finding that for every gram of total protein intake of 3% reduces the risk of sarcopenia and per unit of percent fat increases the risk by 20%. No statistically significant difference was found in physical activity, there is homogeneity between cases and controls regarding MET consumed.
Conclusions: Protein intake is a protective factor against sarcopenia and excessive accumulation of fat is a risk factor for this disorder. It is important to further investigate the relationship between the two in older adults.
