Cardiovascular Health Status Among Community-Dwelling Ecuadorian Natives Living in Neighboring Rural Communities: The Three Villages Study

Knowledge of cardiovascular health (CVH) status in rural communities is essential to implement cost-effective strategies aimed to address the growing burden of cardiovascular diseases in these settings. Here, we report on the CVH status and health metrics of 1508 community-dwellers aged >= 40 years in three neighboring rural villages of Coastal Ecuador (Atahualpa, El Tambo, and Prosperidad). According to the American Heart Association, a poor CVH status is designated when at least one cardiovascular health metric is in the poor range. About 70% of individuals in the villages studied had a poor CVH status, with no overall differences across villages. However, the relative prevalence of poor health metrics varied. Using Atahualpa as the referent village, a multinomial logistic regression model showed that El Tambo residents were more often smokers and had a worse diet, while Prosperidad residents had more high blood pressure but better fasting glucose levels. Probabilities of having poor health metrics were lower in Atahualpa than in El Tambo (p<0.001), but not better than in Prosperidad (p =0.097). Predictive estimates of having poor health metrics were significantly higher in El Tambo than in Atahualpa or in Prosperidad. This comparative study demonstrates that the CVH status of rural populations of coastal Ecuador is basically similar. However, individual health metrics in the poor range were found to vary across villages. While the three villages are generally comparable, interventions should be tailored according to local priorities. The same may occur in other rural communities, but more studies are needed to confirm our findings.
