Objective:

To analyze the determinants of the demand for health services of the elderly among the poorest segments in Colombia.

Materials and methods:

Panel data study based on individualized risk data from an insurer of the subsidized regime in Colombia. Linear regression models were developed to determine health demand under two scenarios.

Results:

Overcrowding, exposure to smoke and rodents maintain a positive relationship with the demand for health services. On the contrary, education, occupation, physical activity, and non-alcohol consumption are protective factors.

Conclusion:

The demographic and epidemiological transition that Colombia is experiencing brings challenges to the health system. The identification of determinants of demand contributes to the implementation of strategies to improve the current and future health system.
