“…Moreover, we found that socioeconomic variables such as unemployment and household assets were significantly related to health check-up behavior, whereas university degree and household income were not. For the unemployment variable, a significant and positive link with health check-up behavior was an unexpected finding, as it did not align with many other studies [ 8 , 61 , 62 ]. One justification for this may be that as our study excludes those participating in mandatory health check programs organized at school or work, all other non-mandatory forms of health check-ups would be greatly accessible to unemployed people, because they would have more time and energy.…”

Background General health check-ups are an important element of healthcare, as they are designed to detect diseases, thereby reducing morbidity and mortality. Recent studies have found that financial literacy promotes preventive healthcare usage and reduces risky health behaviors such as smoking, lack of exercise, and gambling. Based on this evidence, we hypothesize that financial literacy, as a rational decision-making tool, is positively associated with health check-up behavior in Japan. Methods We extracted data on financial literacy, the main explanatory variable of this study, from the 2010 wave of the Preference Parameter Study (PPS) of Osaka University. Data on health check-up behavior as a dependent variable, along with control variables, were obtained from the 2011 PPS wave. Our sample focused on Japan’s middle-aged working population (40–64 years), and we applied probit regressions to test our hypothesis. Results Our final sample size was 2,208 participants after merging the two datasets. Descriptive statistics show that respondents had moderate financial literacy (mean = 0.62, SD = 0.33), low financial education (mean = 0.17, SD = 0.38), and low participation (mean = 31.75%, SD = 46.56%) in the health check-up. The probit regression analysis showed that financial literacy is insignificantly associated with health check-up behavior in Japan (coefficient = -0.0229; 95% CI: -0.2011—0.1551; p-value = 0.801). However, demographic factors such as being male (coefficient = -0.2299; 95% CI: -0.3649—-0.0950; p-value = 0.001), older (coefficient = 0.0280; 95% CI: 0.0188 – 0.0371; p-value = 0.000), and married (coefficient = 0.3217; 95% CI: 0.0728 – 0.5705; p-value = 0.011), as well as risky health behavior such as smoking (coefficient = -0.2784; 95% CI: -0.4262—-0.1305; p-value = 0.000) are significantly related to health check-up behavior. Conclusions Our results suggest that financial literacy insignificantly motivates people to behave rationally and understand the value of health check-ups as a tool for sustainable health.

“…In addition to health literacy, the study also reported that low education level was positively associated with current smoking compared with high education level 11 . Additionally, previous studies reported a significant association between education level and health literacy 22,23 . In this context, further research is necessary to clarify the association between health literacy and current smoking in various countries and regions, stratified by education level.…”

“…Previous studies have reported that there is a negative relationship between anxiety about radiation and participation in health checkups, and that managing radiation anxiety may be important for improving the health of the population after the FDNPP accident [29]. It is possible to explain the low medical exposure due to chest radiography using the radiation dose scale shown in figure 1, and publishing FAQs [8] on radiation for the general public may further help alleviate anxiety.…”

Effective dose is sometimes used to compare medical radiation exposure to patients and natural radiation for providing explanations about radiation exposure to patients, but its calculation is lengthy and requires dedicated measuring devices. The purpose of this study was to identify the most suitable conversion coefficient for conversion of easily measurable dose to effective dose in posterior–anterior chest radiography, and to evaluate its accuracy by direct measurement. We constructed an examination environment using Monte Carlo simulation, and evaluated the variation in conversion coefficients from incident air kerma (IAK), entrance-surface air kerma (ESAK), and air kerma-area product (KAP) to effective dose when the irradiation field size and radiation quality were changed. Effective doses were also measured directly using thermoluminescence dosimeters and compared with the effective dose obtained from conversion coefficients. The KAP conversion coefficient most effectively suppressed the effect of irradiation field size, and was then used to set conversion coefficients for various half-value layers. The optimal conversion coefficient was 0.00023 [mSv/(mGy·cm2)] at 120 kVp (half-value layer = 5.5 mmAl). Evaluation of the direct measurements obtained with various radiation qualities revealed that the accuracy of the conversion coefficient was maintained at ≤ 11%. The proposed conversion coefficient can be easily calculated even in facilities that do not have equipment for measuring effective dose, and might enable the use of effective dose for providing explanations about radiation exposure to patients.
