RESUMO
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.

Hydrogen production was accomplished under visible-light irradiation by using a system consisting of a biomolecule (chlorophyll a), methylviologen, ethylenediaminetetraacetic acid disodium salt and Pt-loaded poly(l-glutamate) (Poly(Glu)), in aqueous decylammonium chloride (DeAC) solution. Spectroscopic studies revealed that chlorophyll a is solubilized in the hydrophobic clusters of Pt-loaded Poly(Glu)-decylammonium chloride. In the Poly(Glu)-DeAC complex, the electron transfer occurred between chlorophyll a and methylviologen leading to hydrogen production. The most noticeable result is that the rate of hydrogen evolution depends on the change from the random coil to the alpha-helix in conformation of Poly(Glu) induced by the cooperative binding with DeAC.
