The main objective of this work is to describe the correlation between sociocultural factors and mature adult self-care capacity in dealing with hypertension in a rural community in Mexico. A cross-sectional observational study was carried out to survey 60 patients registered in the rural community of Cerro de Ortega, State of Colima, Mexico, selected by availability with regard to the development of sociocultural factors and self-care capacity instruments. The analysis involved Pearson's r and linear regression. It was found that the participants mean age was 50.9 years, 75% of patients were women, 83.3% of them were catholic, 42% achieved primary school, 80% were married, 60% worked as housekeepers and 57% of subjects have been treated for 2 to 4 years . The scores of sociocultural factors and self-care capacity showed an r of 0.44 and a significative linear relationship (p<0.05); the same was found between scores of religion, costumes and traditions with self-care capacity (p<0.05). Sociocultural factors had significative correlation and lineal regression with self-care capacity; also, there were correlation between religion, costumes and traditions with self-care capacity. We can conclude that, among the considered sociocultural factors, the dimensions that were more associated with self-care capacity are religion, customs and traditions.
