Recently, the deficiency of emergency care system has become a social issue by the decline in the number of emergency hospitals due to the shortage of doctors in Japanese rural communities. Although the number and distribution of doctors were taken into account when secondary-medical care areas were designated, real transportation time required to reach the emergency hospitals has not been considered enough. The main objective of this study was to clarify the characteristics of accessibilities to emergency hospitals by secondary-medical care sectors in Shimane Prefecture, excluding islands, using a Geographical Information System. We categorized areas within 3 min., 10 min., and 30 min. transportation time to evaluate the accessibility to emergency hospitals by calculating the population of each area. The western areas of Shimane such as Ooda, Masuda and Hamada had a higher proportion of residents with over 30 minutes of transportation time than the eastern parts. This result indicated that there was a disparity in terms of accessibility to emergency hospitals between the eastern and western parts of Shimane Prefecture. Furthermore, we estimated that residents in the Ooda area were forced to take longer transportation time after the closure of the Ooda City Hospital emergency unit. Our study suggested that not only the discussion of healthcare resources but also the consideration of accessibilities to emergency hospitals in a region was important for the planning of health and medical service.

　　Health care plan has been established in each secondary medical area. Although health care plan should be focused on needs of people live in such units, studies with a view from residents’ perspective have not always been considered adequately. The aim of this study was to examine the factors that effect on utilization of health care facilities located outside of the secondary medical area in a rural region. The data included 515 patients with hypertension, 253 patients with hyperlipidemia, and 104 patients with diabetes. Factors relating utilization of health care facilities were assessed by age, sex, employment, number of diseases, body mass index (BMI), carotid plaque score, HbA1c, distance to the nearest clinic, and distance to the nearest bus stop. We conducted a logistic regression analyses of that data divided into two groups; car use and non car use. The result showed that sex, BMI, carotid plaque score and distance to the nearest bus stop were statistically significantly associated with the utilization of health care facilities located outside of the secondary medical area in patients with car use. Whereas, there were no statistically significantly associations in patients with non car use. Our findings suggested that it is important to consider health utilization of patients with lifestyle related diseases for making sustainable health care plan.

Objectives: Prevention of obesity is a high priority of health management at workplaces. We conducted a follow-up study of obesity and obesity-related metabolic disorders in Japanese male workers. Subjects and Methods: Ninety-eight male workers engaged in the operation of a nuclear power plant in Shimane Prefecture, aged 41 ± 8 years in 2006, were subjected to regular health check-ups in 1996 and 2006. Results: The changes in their body weights and metabolic parameters (blood pressure, AST, ALT, γ-GTP, LDL-cholesterol, HDL-cholesterol, triglycerides, glucose and uric acid) were compared by BMI class and age group. Twenty-three percent of the subjects fell within the 23.0 to 24.9 BMI range, and 23% were over 25.0 BMI. Body weight increased significantly, by 3.6 ± 5.3 kg in all subjects, but there was no significant difference in weight gain over the 10 years by age or BMI group. Weight gain was positively associated with metabolic parameters, such as the values of systolic blood pressure, ALT, triglycerides and uric acid, and negatively associated with the value of HDL-C. Conclusions: Japanese male workers, regardless of age and BMI at baseline, experienced an increase of body weight and obesity-related metabolic disorders. Therefore, health professionals in the workplace should consider educating workers about stress-coping methods to reduce job stress, promote a health-supportive environment, such as healthy menus in employee cafeterias and fitness clubs, and be cognizant of high-risk factors in the individual employee.

  As is often the case with rural communities in Japan, a dearth of health resources poses a serious problem in a mountainous region of Shimane Prefecture. Although a medical care plan focusing on needs of people should be devised with a view to building up a sustainable health care system, studies have not always adequately been pursued. The aim of this study was to assess the data on the patients with lifestyle-related health problems to and from health care facilities. A Geographic Information System was used for measuring the travel time and road distance. The data for 255 patients with hypertension, 114 patients with hyperlipidemia, and 42 patients with diabetes were amassed. The results showed that the average travel time and distance were much longer in patients with diabetes than those with hypertension. Statistically no significant difference was observed in severity of diabetes (HbA1c, BMI and LDL-c) and blood pressure levels between patients who received regular treatment at clinics in the two towns and those who went all the way to clinics outside of the towns. In addition, compared with the patients with diabetes aged 75 years or over, the average travel time and road distance for aged of 74 years or younger were much longer. Similarly, compared with the patients with hypertension aged 75 years or over, the average travel time and road distance for aged of 74 yeras or younger were also much longer. These results indicated that the diabetics and the elderly age 74 or younger tended to go to health facilities beyond the secondary-medical care zone. These findings also suggested that a closer cooperation between facilities in the neighboring secondary-medical care zones to improve the quality of medical services and support general practitioners to review the existing disease management program would make it possible to cope with the present situation.

　　The establishment of a sustainable healthcare system based on residents’ needs is an urgent issue in a rural region. For this purpose, considering the structure of a healthcare system, such as the numbers of beds, doctors, and nurses is important. In addition, the study of healthcare utilization using the date gathered through geographic information systems (GIS) would be very helpful in building such a healthcare system. In Japan, however, there are few published studies available on how health services are utilized. The aim of this paper was to review articles of GIS research on healthcare utilization. We conducted a systematic search of published peer-reviewed literature on PubMed. We found 38 articles that satisfied our inclusions criteria for review. Of them, 12 articles had a map for understanding health needs or demands, 23 articles carried analyses of distance and time for health utilizations, and seven articles had a buffer or database for analyses of healthcare utilization. Most of these articles have dealt with pediatric care and emergency care. Given the aging population in a rural region, we concluded that a more evidence-based approach should be taken to rural health focussing on lifestyle-related diseases.

Objectives: The aims of this study were 1) to elucidate the relationship between social capital and health by ward in Tomi City, Nagano Prefecture, in order to clarify the regional social resources available to support long-term care prevention utilizing self- and mutual support of regional residents and 2) to comprehensively investigate the activation of regional networks.Materials and Methods: We analyzed elderly (aged 65 years or older) individual survey data from 7,199 residents from all wards within Tomi City in 2014 (number of valid responses: 5,546; valid response rate: 77.0%). The social capital indicators used for the analysis included participation in community activities, regional managerial position experience, and general trust. The health indicators included self-rated mental health, activities of daily living, and depression. Standards for a “good” result for each indicator were established, and the percentages of each were tallied up by ward. Spearman’s rank correlation coefficient and principal component analysis were used to investigate correlations between social capital and health.Results: The results for overall respondents indicated correlations between participation in sports and hobbies and activities of daily living (p<0.01) and self-rated mental health (p<0.05). Participation in nonprofit organizations/volunteer activities and participation in community center workshops exhibited correlations with activities of daily living (both p<0.05). In respondents aged 65–74 years, participation in community center workshops and general trust were found to be correlated with activities of daily living (both p<0.05). Meanwhile, in respondents aged 75 years or older, correlations were noted between participation in sports and hobbies and participation in nonprofit organizations/volunteer activities and activities of daily living (p<0.05 and p<0.01, respectively). By creating a distribution map using principal component analysis, we were able to grasp the characteristics of the distribution of “community participation/connections with people” and “health” in each ward.Conclusions: Our results point the way forward for future long-term care prevention support in Tomi City by clarifying the correlation between social capital and health by ward.

Objective: Engaging in agriculture greatly affects workers’ lifestyles, particularly related to physical activity. This study aimed to clarify the prevalence of lifestyle-related chronic diseases among workers engaging and not engaging in agriculture in rural areas of Japan.Methods: A total of 4,666 consecutive participants aged ≥40 years (1,929 men and 2,737 women) were recruited during health examinations conducted from 2006 to 2014. For analysis, the participants were divided by sex and age into those engaging in agriculture and those not engaging in agriculture.Results: Engaging in agriculture may be contributing with a low prevalence of dyslipidemia, a constitutive factor of metabolic syndrome, in both sexes between the ages of 40 and 64 years. In the elderly aged ≥65 years, engaging in agriculture may influence the low prevalence of hypertension in men. Hypertension, a strong risk factor for stroke and cardiovascular disease, is very frequent among the Japanese elderly and, therefore, engaging in agriculture may have a significant impact on its prevention and control.Conclusion: In rural areas of Japan, engaging in agriculture may contribute to the control of lipid metabolism in middle-aged individuals and blood pressure in the elderly.
