| Sumario: | The objective of this article was to establish the relationship between health, measured by life expectancy at birth, and economic growth, represented by gross domestic product (GDP) per capita, to estimate the Preston curve for Nicaragua, during the observed period of 1990-2023. This relationship was modeled using a logarithmic function, of the Lin-Log type, which revealed a positive but decreasing association between both variables. Two models were estimated, the first used the gross domestic product (GDP) per capita at current prices as an independent variable, while the second model used the GDP per capita at constant 2015 prices. Both models showed statistical significance, however, the second model, which uses the GDP per capita at constant 2015 prices, showed a better fit to the data and greater precision in the predictions, being considered the most appropriate to represent the relationship between life expectancy and economic growth for Nicaragua. |
