Background: Promoting physical activity among older adults is essential for extending healthy life expectancy. Municipality-led walking programs have been introduced in Japan; however, evidence of their effectiveness in promoting readiness for lifestyle improvement among older adults remains limited. We examined the association between participation in a municipality-led walking promotion program and readiness for lifestyle improvement among community-dwelling older adults. Methods: Data of community-dwelling adults aged ≥65 years who participated in a municipality-led walking promotion program implemented in Zushi City, Japan, in 2021, were compared with those of non-participants selected from the National Health Insurance database. Behavioral readiness was evaluated using the five-stage classification of the transtheoretical model. Pre- and post-intervention stages were assessed in both groups. Associations between participation and behavioral stage were examined using ordinal logistic regression with unadjusted, basic-adjusted, and fully adjusted models, controlling for baseline stage and habitual exercise. Results: Participants in the walking event had higher odds of being at a higher readiness stage than non-participants (unadjusted odds ratio [OR]=2.91; basic-adjusted OR=2.99; fully adjusted OR=2.98). Analyses using a dichotomized transtheoretical model variable also indicated consistently higher odds of being in the action or maintenance stages among participants. Conclusion Our findings suggest that short-term, municipality-led walking initiatives contribute to early-stage behavioral readiness for lifestyle improvement in older adults. They provide a valuable foundation for planning community-based health promotion and long-term care prevention strategies. Further studies are needed to evaluate similar programs across different settings and over more extended periods.

Background: Invasive pneumococcal disease (IPD) is an infectious disease where Streptococcus pneumoniae can be detected in the cerebrospinal fluid or blood.Methods: Eight patients presented to our hospital with adult IPD. We compared with 69 cases of pneumococcal pneumonia treated in our department between 2012 and 2014. None of the patients had a history of pneumococcal vaccine administration.Results: Hematological examination showed the platelet count was significantly lower and the serum C-reactive protein level was significantly higher in the IPD group. There was a significant difference in the use of a respirator and mortality in the IPD group. About antibiotics, Carbapenem and quinolone were used for the treatment of many patients in the IPD group. In the fatal three cases of IPD, the age of all members were 65 years or younger. Two of three had no underlying disease.Conclusion: IPD develops without elderly people and in those without underlying disease. Also, the patients who took a sudden course may result in death. In line with previous studies that have reported the effectiveness of the pneumococcal vaccine, our study findings emphasize the need of administering vaccination for prevention of IPD in person who was younger than 65 years old.
