To examine the impact of age on low health literacy level among residents in Fuyang District of Hangzhou, and to elucidate its interactive effect with other determinants.
A questionnaire survey was conducted among residents aged 15-69 years old by multi-stage stratified random sampling. Data on basic demographic characteristics and health literacy levels were collected. The associations were examined using the Mann-Whitney U test, Chi-square test, the restricted cubic splines (RCS) model, and multivariable-adjusted logistic regression models.Furthermore, multiplicative and additive interaction models were applied to explore the joint effects of age and other influencing factors on low health literacy.
Among the 640 respondents, 417 (65.16%) had a low health literacy level. After adjusting for potential confounders, the RCS model revealed a significant nonlinear dose-response relationship between age and the risk of low health literacy (Pnonlinear<0.01), with an inflection point at 51 years old. Subsequently, multivariate logistic regression analysis using this cut-off value demonstrated that individuals aged over 51 years old had a significantly higher risk of low health literacy (OR=3.377, 95% CI: 2.120-5.378, P<0.05). Regarding interaction effects, an additive interaction was observed between age and educational level (RERI=9.979, 95% CI: 0.389-19.569; AP=0.606, 95% CI: 0.368-0.843; SI=2.814, 95% CI: 1.442-5.492).
Age is an independent influencing factor of low health literacy levels among residents. Further interaction analysis reveals that individuals with advanced age and low educational attainment are identified as the key target population for health literacy promotion and intervention efforts.
