Background:
Motoric Cognitive Risk Syndrome (MCR) is a predementia stage where slow gait speed and subjective memory complaints are present. The purpose of this study was to estimate the prevalence of MCR and assess its relationship with sociodemographic factors and chronic conditions.
Methods:
This is a secondary analysis of the SABE Colombia study conducted in 2015. The analytic sample consisted of 17·577 participants. After determining MCR prevalence, logistic regression was performed to examine the correlates of MCR.
Findings:
The prevalence of MCR was 10·71 %. The median age was 71 years and women composed 74·63 % of the MCR group. After adjusting for confounding variables MCR was associated with increasing age (OR 1·69, CI 1·43 - 1·92), no or low education (OR 1·99, CI 1·67- 2·37), MMSE (OR 0·93, CI 0·91 - 0·95) and chronic conditions such as mental disorders (OR 1·36, CI 1·11-1·67), history of myocardial infarction (OR 1·24, CI 1·04 - 1·47), hypertension (OR 1·23, CI 1·08 - 1·40) and diabetes (OR 1.18, CI 1.01 - 1.37).
Interpretation:
This study found a prevalence of 10·71 % of MCR in Colombian older adults. Additionally, MCR was associated with chronic conditions and sociodemographic factors identified in prior studies. These results increase the awareness of a novel predementia stage whose identification can be performed by clinicians in the outpatient clinic, minimizing the cost of a full neuropsychologic evaluation performed in a memory clinic.

Insights
Motoric Cognitive Risk Syndrome (MCR), a predementia stage, affects 10.71% of older adults. MCR is linked to age, low education, and chronic conditions like hypertension and diabetes.
Area of Science:
- Gerontology
- Neurology
- Public Health
Background:
- Motoric Cognitive Risk Syndrome (MCR) is a predementia stage characterized by slow gait and memory concerns.
- Identifying MCR is crucial for early intervention in cognitive decline.
Purpose of the Study:
- To determine the prevalence of MCR in Colombian older adults.
- To investigate the association between MCR and sociodemographic factors and chronic conditions.
Main Methods:
- Secondary analysis of the 2015 SABE Colombia study data.
- Involved 17,577 participants.
- Logistic regression analysis was used to identify MCR correlates.
Main Results:
- The prevalence of MCR was 10.71%.
- MCR was significantly associated with older age, lower education levels, and conditions including mental disorders, myocardial infarction history, hypertension, and diabetes.
- The MCR group was predominantly female (74.63%) with a median age of 71.
Conclusions:
- MCR affects over 10% of Colombian older adults, consistent with prior research on associated factors.
- Early identification of MCR in clinical settings is feasible and cost-effective.
- This research highlights MCR as a significant predementia stage requiring clinical attention.
