In the present study, we examined whether regional differences in patient mobility and mortality ratios exist in Japan.Methods　We investigated 10,713 patients with cancer aged ≤18 years, diagnosed between 2016 and 2019, registered in the national cancer registry data. The patients were divided into two categories based on their residence at diagnosis: urban and rural. Urban areas were defined as metropolitan or urban areas according to the 2015 census or as prefectural cities; all other areas were defined as rural. Additionally, we divided the patients into two groups based on the one-way travel time to the treatment hospital (≤1 h or >1 h), as estimated from location information at the community level using route-planner web services. Next, we calculated the percentage of patients who received treatment within their residences in both areas and for each treatment type. We compared the percentage of distant metastasis in all cancers and each diagnosis group between the two areas using the chi-square test. We finally applied Cox proportional hazard models to obtain adjusted mortality hazard ratios for urban versus rural areas and travel times of ≤1 h versus >1 h.Results　Overall, 77% of the patients were classified as urban residents. The percentages of patients receiving treatment within their residency, secondary medical care area, prefecture, and regional block levels were 22-46%, 80-87%, and 95-99%, respectively. Only central nervous system tumors (III) showed a significant difference in the percentage of distant metastases, which were more common in urban areas (6% vs. 3%). The adjusted mortality hazard ratios were not significantly different between urban and rural areas for all cancers or each diagnosis group. The travel time comparison yielded significant differences of 1.17 for all cancers and 2.57 for lymphomas (II).Conclusion　Approximately 80% of the patients received treatment within their prefecture, although a few traveled long distances across regional blocks. We observed no differences in the mortality ratio between urban and rural areas, although significant differences were found in all cancers and one cancer in the travel burden comparison. These results highlight the need for continued evaluation of the increasing trend in patient travel burden and its impact on survival, as childhood cancer treatment has become centralized in Japan.</p>","PeriodicalId":72032,"journal":{"name":"[Nihon koshu eisei zasshi] Japanese journal of public health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed the populations' demographic characteristics, number of public health nurses (PHNs), and human base for such services. The process was evaluated using the screening uptake rates for countermeasure-type cancer screening and detection indices.Methods　The data included municipal population figures, areas, and national health insurance enrolments, all sourced from a government statistics portal (e-Stat). We obtained the number of PHNs per 100,000 population from PHN activity area surveys, information on municipal colorectal cancer screening from public health centers (PHCs) and health promotion project reports, and cancer detection indices from the National Cancer Registry data. The analysis covered 1,234 municipalities with populations of ≥10,000 and ≥50,000, categorized into three groups based on the presence of PHCs. The internal structures were compared using multiple regression analysis.Results　The number of PHNs per 100,000 population was categorized as follows; <50,000 population group (42.9), ≥50,000 population group (24.3), and PHC-present city group (16.4).Among these groups, the mass and individual screening rates were 96.2% and 47.7%, 69.1% and 91.5%, and 83.7% and 69.9%, respectively. The average uptake rates of countermeasure-type screenings and detailed examinations were 10.6-13.7% and 68.4-75.3%, respectively. In both cases, the <50,000 population and PHC-present city groups exhibited high and low values, respectively. However, the proportion of patients with \"early cancer\" detection was approximately 42% in all groups.Multiple regression analysis, using the countermeasure-type screening uptake rate and colorectal cancer detection indices as dependent variables, revealed that in the <50,000 population group, in which mass screening was prevalent, the number of PHNs was significantly positively correlated with the countermeasure-type screening uptake rate and proportion of \"new cancers\" detected by screening.Contrastingly, the PHC-present city group showed no correlation between the number of PHNs and countermeasure-type screening uptake rate, but a highly detailed examination uptake rate was significantly positively correlated with the proportion of \"early cancer\" detection.Conclusion　In municipalities without PHCs, countermeasure-type screening uptake rates, particularly mass screening rates, were positively correlated with the number of PHNs and cancer detection indices.

Shortly after the first case of SARS-CoV-2 B.1.1.529 (Omicron) variant was reported abroad, the Japanese government strengthened border control measures, including quarantine procedures and public health official involvement, for incoming travelers. This study aims to propose effective and efficient border control measures to prevent future outbreaks of emerging and re-emerging infectious diseases.Methods　Border control measures implemented between November 2021 and mid-January 2022 were analyzed from three perspectives: chronological changes in government notifications, the situation of in-flight contacts and Omicron cases, and the support system for coronavirus-disease 2019 control department of the Ota City Public Health Center. Additionally, a questionnaire survey was conducted among public health centers with jurisdiction over the top four international airports. This survey aimed to assess the effectiveness of the support system, evaluate cooperation with related organizations, identify common issues faced by public health concerns, and gather suggestions for improvements in future border control measures.Results　The definition and treatment of in-flight contacts of Omicron-positive individuals were initially outlined on November 30, 2021, and underwent frequent revisions until January 14, 2022. Between December 1, 2021, and January 12, 2022, only one Omicron case was identified among the 470 tests conducted on in-flight contacts. However, out of 136 additional domestic specimens collected (including 57 positives for genetic analysis), 40 were confirmed Omicron positive. The results of the questionnaire survey across the four public health centers largely mirrored the issues and suggestions identified by Ota City officials. A significant portion of these issues arose from managing temporary non-Japanese residents staying near international airports.Conclusion　Border control measures should be implemented to delay the domestic spread of the virus. In this reason, it is crucial to avoid placing an undue burden on public health officials responsible for handling domestic infections. Since response policies and target definitions may need to adapt to unknown pathogens, they may be changed frequently, baffling the officials; however, a system for collecting real-time data from frontline sites and making evidence-based decisions is essential.

People were asked to stay at home unless necessary, and studies conducted in Japan and other countries have investigated the impact of these restrictions on the lives and health of older adults. While some studies have focused on sleep, a crucial aspect of the health of older adults, little is known about the relationship between sleep and various lifestyle changes experienced by older adults in Japan during the COVID-19 pandemic. Herein, we aimed to investigate the factors associated with changes in sleep duration among older adults before and after the spread of COVID-19.Methods　A random sample of 1,808 men and women aged 65-84 years who lived in Fukushima City, Fukushima Prefecture, Japan was selected. A self-administered anonymous survey was mailed to the participants. Logistic regression analysis was used to identify the factors associated with decreased sleep duration compared to the COVID-19 pre-pandemic. Factors such as basic attributes, lifestyle changes compared with that during pre-pandemic period, stress levels, and involvement with the community were considered in the analysis.Results　Of the 1,808 distributed surveys, 1,305 were returned (response rate: 72.2%). After excluding participants with missing data (n＝108), 1,197 responses were included in the final analysis (valid response rate: 66.2%).

The survey covered three main areas; health-promoting activities for patients/users, the community, and staff (options), willingness to expand activities (10-point scale), and facilitating and inhibiting factors (open-ended responses). Responses were analyzed according to facility type, and activities were categorized according to the 2020 Standards for Health-Promoting Hospitals and Health Services (The 2020 HPH Standards).Results　The response rate was 100%. Activities were implemented across all facilities.

We included 7,984,451 Japanese individuals (3,992,202 men and 3,992,249 women) aged 30-79 years (9.9% of the total census population). Death records with a unique \"linkage key\" were linked to these records using the deterministic linkage method (five-year cumulative proportion of deaths; 5.6% for men and 2.5% for women). Inverse probability weights were calculated from the ratio of the total to sample population, using the distributions of sex, age, prefecture, educational attainment, and occupation. Weighted age-standardized mortality rates (ASMR) and ASMR ratios by educational level were calculated, and their variations by prefecture were analyzed.Results　Estimated all-cause ASMRs (per 100,000 population) for men were 1,025 (95% confidence interval [CI]; 1,013-1,037) for high education (university graduation) and 1,245 (95% CI; 1,238-1,253) for middle/low education (junior/senior high school graduation).
