The association between adult child education and cognitive functioning among older parents: A cross-national comparison of diverse contexts.

Introduction: The association between adult child educational attainment and older parent's cognitive health may vary across diverse contexts but cross-national comparisons have been limited by differences in outcome assessment, study design, and analytic choices.

Methods: We used harmonized data with comprehensive cognitive assessments from the United States (N = 3088), India (N = 3828), and Mexico (N = 1875) to estimate associations between adult child education and older adults' cognitive functioning using linear regression models adjusted for respondent and family-level socio-economic status (SES) in each study.

Results: Each additional year of offspring education was associated with 0.

Effects of ozone applied by spinal endoscopy in patients with chronic pain related to failed back surgery syndrome: a pilot study.
