Objetivo: comparar el riesgo de morir por deficiencias nutricionales en las personas de 50 años y más de edad, con respecto a los menores de 50 años, Colombia - Argentina. Método: estudio descriptivo retrospectivo con 21.479 registros de defunción con causa básica de mortalidad relacionada con la malnutrición; se realizó un análisis comparativo de las tasas ajustadas de mortalidad, utilizando el método directo y se calcularon proporciones. Resultados: el 91,1% de las defunciones en Argentina y el 73% de las de Colombia, fueron en mayores de 50 años; en cuanto al sexo los hombres colombianos tienen mayor riesgo que los argentinos en un 94,4% de morir y para el caso de las mujeres en un 42,8%. Conclusiones: estas muertes son prevenibles mediante políticas y programas de nutrición adecuados, es necesario seguir monitoreando la situación de mortalidad por deficiencias nutricionales en ambos países y tomar medidas para mejorar la nutrición de la población, especialmente de las personas más vulnerables.

Highlights There is a high prevalence of consumption of psychoactive substances, especially alcohol, marijuana, and popper. Popper is one of the psychoactive substances that is emerging among the population; it must be carefully monitored. The consumption of psychoactive substances is statistically and epidemiologically associated with having casual couples and sexual work. The consumption of psychoactive substances increases the probability of having unprotected sexual intercourses. Introduction: The use of psychoactive substances (PS) in the population is a current problem that affects a large part of humanity, with diverse consequences.   Objective: To analyze the factors associated with the consumption of PS among men who have sex with other men (MSM) in three Colombian cities. Material and Methods: This cross-sectional descriptive study used the respondent-driven sampling (RDS) method and obtained a sample of 1301 MSM. The association between the sociodemographic and personal characteristics and the consumption of PS was assessed using the chi-square test. Prevalence ratios were calculated along with their 95% confidence intervals. For the multivariate analysis, a Poisson regression with a log link and robust estimator was employed to explore the factors associated with PS use. Result: The prevalence of consumption of PS in the last year was 87%, prevailing the consumption of alcohol, marijuana, and poppers. Having occasional partners (PR: 0.44; 95% CI 0.29 - 0.67), attending public places or establishments such as bars and saunas (PR: 3.39; 95% CI 2.34 - 4.91), sex work, and not using a condom in the last sexual encounter (PR: 2.10 95% CI 1.37 - 3.22) are factors associated with the use of these substances.   Discussion: There is evidence of a high prevalence of recreational use of PS, even higher than that found in the general population. Conclusion: A high prevalence and association with risky sexual behaviors is confirmed, which requires promotion and prevention actions to reduce the use of these substances.
