Prevalence and Clinical Associations of Osteosarcopenic Obesity and Frailty in Mexican Elderly Women: A Cross-Sectional Pilot Study

The coexistence of obesity, osteoporosis, and sarcopenia has been associated with adverse outcomes such as risk of falls, fractures, immobility, disability and frailty, yet data from Latin American populations are scarce. This study aimed to determine the prevalence and associations of obesity, osteoporosis, and sarcopenia—individually and combined—with frailty in Mexican elderly women. We conducted a cross-sectional study in which patients with body mass index < 18.5 kg/m2, uncorrected sensory deficits, immobility, musculoskeletal diseases, or patients with implanted devices were excluded. Frailty was assessed using the FRAIL scale, obesity by body fat percentage, osteoporosis according to American Association of Clinical Endocrinology (AACE) guidelines and sarcopenia following the European Working Group on Sarcopenia in Older People-2 (EWGSOP2) recommendations. A total of 115 participants aged ≥60 years were assessed between January and June 2025. Frailty was present in 21.7% of the patients; 67.0% had obesity, 72.2% osteoporosis, 20.0% sarcopenia and 13.0% osteosarcopenic obesity. Sarcopenic phenotypes were associated with frailty: odds ratios (95% CI) were 3.05 (1.12–8.26) for sarcopenia, 4.23 (1.42–12.55) for sarcopenic obesity and 3.98 (1.28–12.40) for osteosarcopenic obesity. Sarcopenic phenotypes showed associations with frailty in Mexican elderly women.
