Cohort analysis reveals parental age influences health outcomes in older adults, suggesting implications for policy.

This analysis investigates how the age of parents at childbirth affects long-term health outcomes in their offspring.
Prospective cohort study using data from the Chinese Health and Longevity Longitudinal Survey (2008–2021).
Assessed parental age, functional independence (ADL), cognitive function (MMSE), and mortality.
Compared health outcomes based on maternal and paternal age categories.
Older maternal age (≥ 37 years) linked to higher odds of ADL limitations and cognitive dysfunction.
Older paternal age (≥ 43 years) associated with lower odds of ADL limitations and cognitive dysfunction.
No direct link found between parental age and offspring mortality, but reduced mortality risk was noted with increasing paternal age among less educated parents.

Li et al. (2026) studied this question.
