The Impact of Health Literacy on Exercise Knowledge

By Vivek Sethumadhavan

Study Objective
To examine the association between health literacy and exercise knowledge.
Study Design
Data for this secondary data analysis came from the Physical Activity and Life Styles (PALS)
randomized control trial from 2004-2007 of Emory University (Atlanta, GA) employees.
Using data col ected at baseline, the association between exercise knowledge and health
literacy was examined by constructing multivariate linear predictive models and through
multivariate logistic regression models with adjustment for age, race, income, and education.
Results
Compared to those with limited health literacy, those with adequate health literacy were
younger, white, better educated, earned more annual y on average, but did not vary
meaningful y in exercise knowledge. Multivariate linear modeling revealed a very weak linear
relationship between health literacy and exercise knowledge (R2 = 0.05, p = 0.07).
Multivariate logistic modeling, similarly, demonstrated no statistically significant association.
Those with limited health literacy only demonstrated a 2% increased odds of low exercise
knowledge, compared to those with adequate health literacy (Odds Ratio = 1.02; 95%
confidence interval: 0.60, 1.7). However, demographic associations with exercise knowledge,
most notably education level, demonstrated a statistical y significant direct trend.
Conclusions
The results of this study are inconclusive. While health literacy was not observed to be
meaningful y associated with exercise knowledge, demographic associations with exercise
knowledge adds to the understanding of those individuals who lack adequate exercise
knowledge. Nevertheless, the importance of increasing the physical activity and health
literacy of Americans are both critical endeavors for American public health.
