  • Association of repeated high serum osmolarity with cognitive function in older Japanese adults in a KOBE study subanalysis

    　View Summary

    The relationship between serum osmolarity and cognitive function has not been fully characterized. This study aimed to examine the cross-sectional association between repeated high serum osmolarity and cognitive performance among elderly community residents. We performed a subanalysis of the Kobe Orthopedic and Biomedical Epidemiological Study, including residents aged ≥ 75 years who completed the Japanese Montreal Cognitive Assessment (MoCA-J) in 2016–2017 (n = 127), 2018–2019 (n = 71), and 2020 (n = 16). Serum osmolarity was obtained from the data in the 2012–2013 survey and in the 2016–2017 survey. MoCA-J scores were dichotomized at ≤ 22 versus > 22. Multivariate logistic regression adjusted for demographic, lifestyle including daily non-alcohol drink intake, seasonal, and clinical covariates to assess associations between osmolarity status and cognitive group. Among 214 participants (mean age 76.2 ± 1.3 years; 56% female), high osmolarity (≥ 300 mOsm/L) in 2012–2013 was associated with MoCA-J ≤ 22 (OR 2.67, 95% CI 1.29–5.53, p = 0.008). A similar association emerged for 2016–2017 measurements (OR 6.12, 95% CI 1.46–25.61, p = 0.013). Participants with high serum osmolarity at both time points showed a stronger cross-sectional association with lower MoCA-J scores (OR 17.64, 95% CI = 1.8–184.83, p = 0.017). No significant association was observed between daily non-alcoholic drink (NAD) intake and either MoCA-J scores or serum osmotic pressure. Repeated high serum osmolarity was cross-sectionally associated with lower cognitive performance in Japanese community-dwelling older adults. While NAD intake showed no significant association, further research is needed to explore the potential role of serum osmolarity in cognitive health. These findings warrant confirmation in larger prospective studies.

    　View Summary

    Objectives: Use of commercially available mobile health (mHealth) applications in supporting lifestyle improvements has become popular in recent years. However, the effectiveness of advice promoting the use of such applications based on individual behavioral goals in a health guidance setting remains unclear. This study explored how guiding participants of the Specific Health Guidance (SHG) program, a Japanese public health initiative to prevent cardiovascular disease, to use commercially available mHealth applications impacted their application usage, lifestyle habits, and cardiovascular risk factors. Methods: In this multicenter, randomized, open-label, parallel-group comparison study, 156 individuals with a history of SHG participation and who were engaged in the Motivational Health Guidance program (a type of SHG) in 2021 were assigned to intervention (n = 76) or control (n = 80) groups. Whereas both groups received standard guidance, the intervention group also received recommendations for mHealth applications based on their individual behavioral goals. The participants' application usage, behavioral changes, and body weight were assessed after 3 months, with health checkup data evaluated after 1 year. Results: The proportion of mHealth application users after 3 months was significantly higher in the intervention group (68.4%) than in the control group (40.0%). The intervention group also reported a significantly greater weekly frequency of mHealth application usage. Moreover, the intervention group reported a significantly decreased change in triglyceride levels after 1 year compared with the control group. Conclusions: Recommending commercially available mHealth applications in a health guidance setting significantly increased the number of mHealth application users and their frequency of use.

    　View Summary

    Hypertension is the greatest risk factor for cardiovascular diseases and significantly contributes to cardiovascular mortality. In Japan, the hypertensive population is estimated at 43 million, with only 27% achieving well-controlled blood pressure (BP). The onset of major cardiovascular events, including stroke, myocardial infarction, heart failure, and aortic dissection, frequently occurs during the early morning hours. Accordingly, for over 20 years, the Japanese Society of Hypertension (JSH) has prioritized the management of early morning hypertension and has emphasized the importance of antihypertensive treatment guided by home BP in its treatment guidelines. However, even among hypertensive patients with multiple medications, control of morning BP remains suboptimal, with fewer than 30% achieving target levels below 130/80 mmHg. To address this serious situation, JSH announced their Declaration for the Eradication of Morning Hypertension in 2025, in conjunction with the release of the Guidelines for the Management of Elevated Blood Pressure and Hypertension 2025. The primary specific measure of the declaration involves the Asakatsu BP Action Plan – the Morning Blood Pressure 130 Campaign – which encourages individuals to monitor their morning blood pressure (BP) in various settings, such as homes, workplaces, and BP kiosks set up in public spaces. Additionally, JSH is promoting a Systematic Review Project to raise awareness of the importance of early morning hypertension management nationally and internationally, and a Data Science Project to examine how digital technology can contribute to the promotion of personalized and anticipation medicine through “digital hypertension” research.
