Key result
Lower functional health literacy was associated with a higher likelihood of hypertension (P=0.003) and diabetes (P=0.02), while higher health literacy correlated with lower systolic blood pressure.

Is there a relationship between health literacy, hypertension knowledge, and blood pressure levels in middle-aged Japanese adults?
Lower health literacy and hypertension knowledge are associated with poorer health status and higher blood pressure levels in middle-aged Japanese adults.

Supports literacy assessment in hypertension care; leaves open causality and intervention effects.
BACKGROUND: With the growth in the popularity of the Internet, individuals' skills in finding and applying information about health issues [health literacy (HL)] are affecting their health behaviors. This study aimed to examine functional HL (FHL), critical HL (CHL), and hypertension knowledge (HK) among middle-aged Japanese adults. In addition, to measure health outcomes, we examined the relationship between HL, HK, and blood pressure (BP) level. METHODS: The study included middle-aged participants who received an annual health check-up at an urban clinic in Japan. FHL, CHL, and HK were assessed using structured questionnaires. In addition, BP was obtained from the electronic medical record. RESULTS: Participants included 139 women and 181 men with a mean age of 54.4 years (standard deviation = 0.69). Individuals with lower reading comprehension scores in FHL were more likely to have a history of hypertension (P = 0.003) and diabetes mellitus (P = 0.02). Individuals with lower CHL had significantly higher rates of current smoking (P = 0.03) and men with lower CHL had a significantly higher waist circumference (P = 0.03). There was a significant relationship between sex and HK (P = 0.03). Systolic BP in women with higher HL and HK was significantly lower than in men with higher FHL (P < 0.001), CHL (P = 0.01), and HK (P = 0.001). CONCLUSION: Lower HL and HK were associated with a poor health status and BP level in middle-aged participants. Further research is needed to examine the role of health management in improving outcomes and to address disparities between individuals with higher and lower HL.

Shibuya et al. (2011) conducted a cross-sectional in General health (middle-aged adults) (n=320). Health literacy and hypertension knowledge vs. Lower health literacy and hypertension knowledge was evaluated on Blood pressure level and health status (history of hypertension, diabetes, smoking, waist circumference). Lower functional health literacy was associated with a higher likelihood of hypertension (P=0.003) and diabetes (P=0.02), while higher health literacy correlated with lower systolic blood pressure.
