BUENDIA, Richard G et al. Is there sarcopenia in patients under 30 years by bioelectrical impedance criteria?. Acta Med Colomb [online]. 2015, vol.40, n.2, pp.132-137. ISSN 0120-2448.

Sarcopenia is a disease detected mainly in the elderly, and its prevalence in young people is unknown. This study aims to determine the prevalence of sarcopenia in patients under 30 years by bioelectrical impedance and determine its associated factors in patients attending endocrinology consultation of Specialists Center Colsubsidio Bogota. Methodology: cross sectional study. The correlation between total body muscle and other anthropometric parameters such as weight, height, total body fat, visceral fat, sex and age was established. Factors associated with sarcopenia were determined by multivariate analysis. Results: 501 patients, 315 women (62.87%) and 186 men (37.13%). Prevalence of sarcopenia found in patients under 30 years was classified as moderate in 60.53% (n = 46) and severe 22.37% (n = 17) p <0.001; 31.75% was associated with overweight or obesity p <0.001. Besides, there was an inverse correlation between the percent of total muscle and age, weight, total body fat and visceral fat for both women and men respectively p <0.01. Independent factors associated with sarcopenia were male gender OR = 1.09x 10¹⁶ (95% CI 7.37 x 10¹¹ -1,62 x 10²⁰) p <0.001; age OR = 1.15 (95% CI 1,085-1.22) p <0.001 and total body fat OR = 1.9 (95% CI 1.59-2,26) p <0.001. Conclusion: the definition of sarcopenia focuses on elderly patients, and it is interesting how loss of muscle mass can be seen from an early age, associated with overweight or obesity that might correspond to "sarcopenic obesity." We believe that a definition of sarcopenia where young patients be included should be made. (Acta Med Colomb 2015; 40: 132-137).
