dc.description.abstractBackground and objective: The global aging population has led to increased noncommunicable diseases, often linked to poor diet and declining muscle strength and mass. This study assessed leucine intake and sarcopenia indicators among 181 adults aged 60–80 in Santiago, Chile, participating in the Program for Complementary Food in Older People (PACAM), with 80% being women. Methods: Sarcopenia was evaluated through muscle strength and mass using the EWGSOP2 criteria for its identification. Results: 78.45% of participants did not meet the recommended leucine intake of 3 g per day and sarcopenia was identified in 17.13% of them. The skeletal muscle index was 48.07%, and hand grip strength was 26.52%, with men showing significantly higher grip strength (48.60% vs. 28.80%, p = 0.00). Inadequate leucine intake was more common in those aged 60–75 (85.9%) than those over 75 (p = 0.03). No significant differences in BMI, grip strength, or muscle mass were found between those with adequate and inadequate leucine intake, and PACAM food consumption did not significantly affect these parameters. A sub-analysis showed significant differences in grip strength among powdered dairy drink consumers (35.20% vs. 17.80%, p = 0.01). Conclusions: Chilean elderly participating in PACAM present a high prevalence of sarcopenia and leucine deficiency among with no notable benefits from PACAM foods intake. Despite the limitations of the local body composition assessment method, this research addresses a critical public health issue in Chile. Future studies should evaluate physical performance and focus on leucine supplementation to clarify its effects on sarcopenia.
