Age- and Sex-Specific Impact of Health Literacy on Healthy Lifestyle Characteristics among Japanese Residents in a Rural Community

Abstract

The study aimed to examine age-and sex-specific associations between health literacy (HL) and healthy lifestyle characteristics. The cross-sectional study was conducted to examine a total 1348 Japanese participants (613 male and 735 female) who took the health check-up program in April 2013, at Tsumagoi Village, Japan. Information was collected by self-administered questionnaire on three communicative and two critical HL items, and healthy lifestyle characteristics listed in Breslow's seven health practices. In multivariate logistic analysis, high HL (≥18) was significantly associated with healthy lifestyle characteristics in both non-elderly (<65 years old) and elderly (≥65 years old) [Odds ratio (OR) = 1.40, 95% Confidence interval (CI) = 1.13 -1.75 for non-elderly, OR = 1.34, 95% CI = 1.02 -1.76 for elderly], as well as female participants (OR = 1.43, 95% CI = 1.06 -1.94), while the significance was borderline in male participants (OR = 1.34, 95% CI = 0.96 -1.88). Among 5 HL items, the ability to extract health-related information was significantly associated with healthy lifestyle characteristics (OR = 1.52, 95% CI = 1.11 -2.07 for non-elderly, OR = 1.55, 95% CI = 1.04 -2.30 for elderly, OR = 1.95, 95% CI = 1.28 -2.97 for female participants. HDL-C concentration in the high HL group was significantly higher than that in the low HL group.

The present study revealed a positive association between HL and healthy lifestyle characteristics, which suggests that people are likely to engage in health-promoting behaviours based on access and ability to understand medical information for both age groups and female participants. Significant findings among female participants may be emphasized since it's important from the entire family's perspective as women are the caretakers of the family. These findings may indicate the importance of comprehensive assessment, including HL, for health promotion in the community.

The Associations Among Individual Factors, eHealth Literacy, and Health-Promoting Lifestyles Among College Students

“…Thus, we adopt Pender’s HPM and IMeHU to explore the association between eHealth literacy and multiple types of health behaviors. A number of studies have found a positive relationship between health literacy and health-promoting behaviors [13-15]. For example, studies have found a significant association between health knowledge and health-promoting lifestyles among women of childbearing age [16].…”

Association between health literacy and metabolic syndrome or healthy lifestyle characteristics among community-dwelling Japanese people

“…Individuals with adequate HL are considered likely to adopt healthy lifestyles [ 14 ], and a brief questionnaire was developed to easily assess HL [ 15 ]. However, only a few studies have estimated the association between HL and healthy lifestyle characteristics among Japanese people [ 15 – 17 ], and reports on the association between HL and prevalence of metabolic syndrome are especially limited.…”
