  Objetivo. Revelar si el síndrome de riesgo cognitivo motor (SCM) se asocia con caídas, caídas recurrentes y caídas complicadas en adultos mayores mexicanos. Material y métodos. Análisis secundario del Estudio Mexicano de Salud y Envejecimiento. El SCM se evaluó en 2012 y los desenlaces relacionados con caídas (recurrente [≥2], complicado [necesidad de tratamiento médico] y número) en 2018. Se realizó análisis de riesgos competitivos (subhazard ratios [sHR]) y regresión binomial negativa (número de caídas, razones de tasas de incidencia [IRR]).Resultados. De 1 929 participantes la mediana de edad fue de 62 años y 58.3% eran mujeres. La prevalencia de SCM fue de 17.4% y se asoció con caídas sHR 1.11 (inter-valo de confianza [IC] 95%: 1.11,1.12), caídas recurrentes sHR 1.16 (IC95%: 1.15,1.16), caídas complicadas sHR 1.25 (IC95%:1.24,1.25) y número de caídas (IRR 1.19, IC95%: 1.01,1.40;p= 0.039).Conclusión. Los resultados muestran que el SCM se asocia de forma independiente con caídas y otros desenlaces relacionados. Aumentar la evidencia sobre cómo el SCM se anti-cipa a los síndromes geriátricos como las caídas podría conducir a acciones para intervenir estos problemas.

  Objective. To reveal whether motoric cognitive risk syndrome (MCR) is associated with falls, recurrent falls, and complicated falls in older Mexican adults. Materials and methods. This is a secondary analysis of the Mexican Health and Aging Study. MCR was assessed in 2012 and included fall-related outcomes (recurrent [≥2], complicated [need for medical treatment] and number) in the 2018 follow-up. Competing risks analysis was performed, and subhazard ratios (sHRs) were estimated, adjusting for different variables. Negative binomial regression was used to estimate the incidence rate ratio (IRR) of the number of falls. Results. A total of 1 929 participants were included, with a median age of 62 years and 58.3% female. The prevalence of MCR was 17.4% and was associated with falls sHR 1.11 (95%CI: 1.11, 1.12), recurrent falls sHR 1.16 (95%CI: 1.15, 1.16) and complicated falls sHR 1.25 (95%CI: 1.24, 1.25). The number of falls was also independently associated with baseline MCR (IRR 1.19; 95% CI 1.01, 1.40; p=0.039). Conclusion. MCR is independently associated with falls. Increasing the evidence on how MCR anticipates burdensome problems in older adults could lead to actions to halt them; therefore, including it in screening assessments could be clinically useful.
