Assessment of sarcopenia, frailty, and anthropometric parameters in older adults affiliated with INAPAM centers in Cajeme, Sonora

The objective of this study was to analyze the association between sarcopenia, frailty, and anthropometric parameters in older adults. An analytical cross-sectional study was conducted in 42 older adults affiliated with one of the centers of the National Institute for Older Adults, Cajeme, Sonora, Mexico. Anthropometric measurements were performed (weight, height, waist circumference, mid-arm circumference, skinfold, and calf circumference), sarcopenia risk was assessed with the SARC-F questionnaire, frailty with the frailty scale, and grip strength was obtained by dynamometry; bone mineral density was determined by dual-energy X-ray absorptiometry (DXA). In the study population, we found a mean age of 69.95 ± 4.64 years. The prevalence of overweight + obesity was 59.5%, 33.3% had sarcopenia according to calf circumference, while 45.2% were classified as prefrail and 19.1% as frail. According to SARC-F, 33.3% of the older adults were at risk of sarcopenia, and 47.6% had osteopenia. A weak positive correlation was observed between bone mineral density and waist circumference (r = 0.385, p < 0.001). The frailty score was strongly correlated with SARC-F (r = 0.690, p < 0.001). The older adults had a high frequency of sarcopenia risk, as well as osteopenia and osteoporosis; a high prevalence of frailty was also identified. These results indicate that it is necessary to implement prevention programs and ongoing nutritional surveillance in this vulnerable population.
