Overview

Randomized trial examines social engagement improvement in aging adults, indicating positive outcomes from health policy changes.

Key Points

  • The aim is to evaluate how the Healthy City Pilot program influences social engagement among middle- and older-aged adults in China.
  • Four waves of panel data from the China Health and Retirement Longitudinal Study (CHARLS) covering 2011 to 2018 were analyzed.
  • A Difference-in-Differences (DID) model was used to estimate causal effects on social engagement.
  • Exploratory mechanism-consistency checks were conducted to assess the roles of physical and mental health.
  • The HCP program significantly improved social engagement with a beta of 0.582 (P < 0.01).
  • Effects were more significant among males, those with lower education levels, younger adults, and individuals with a spouse.
  • Physical and mental health were found to play a limited role in mediating the program's effects.
