Social connections and risk of incident mild cognitive impairment, dementia, and mortality in 13 longitudinal cohort studies of ageing.

ABSTRACT:

Introduction

Previous meta-analyses have linked social connections and mild cognitive impairment, dementia, and mortality. However, these used aggregate data from North America and Europe and examined a limited number of social connection markers.

Methods

We used individual participant data (N = 39271, M_age  = 70.67 (40-102), 58.86% female, M_education  = 8.43 years, M_follow-up  = 3.22 years) from 13 longitudinal ageing studies. A two-stage meta-analysis of Cox regression models examined the association between social connection markers with our primary outcomes.

Results

We found associations between good social connections structure and quality and lower risk of incident mild cognitive impairment (MCI); between social structure and fun
