Low life expectancy has always been caused mostly by high infant and child mortality
In demography, the life expectancy of a modern population is calculated by fitting a curve to the most recent infant and child mortality (< 5 years old) measurements. Not relevant to ancient Rome, but for the modern world life expectancy is not just heavily influenced by infant and child mortality, but is rather 100% a measure of infant and child mortality.
