Factors associated with "Ikigai" among members of a public temporary employment agency for seniors (Silver Human Resources Centre) in Japan; gender differences.

BACKGROUND: "Ikigai" is culturally defined in the society of Japan as a comprehensive concept describing subjective well-being. It is considered to be related to life-satisfaction, self-esteem, morale, happiness as well as evaluation towards meaning of one's life. Although previous studies examined factors associated with Ikigai with smaller samples, consistent results have not been obtained, especially from the viewpoint of gender differences. Identification of gender-specific factors related with Ikigai among the elderly, may be of value to enhance subjective well-being. METHODS: Self-administered questionnaires were distributed among 4,737 randomly selected members of the Silver Human Resources Centre (SHRC), a public temporary employment agency for seniors, in Osaka, Japan. This represents about 10% of all registered members (n = 41,593) in the 38 SHRC centres in Osaka. A total of 4,376 subjects (male: 2,913; female: 1,463) provided a satisfactory response to the questionnaire (response rate: 92%). The status whether they have "Ikigai" or not was evaluated by self-anchoring scale ranging from 0 to 5 (0 = lowest rate and 5 = highest rate of having "Ikigai"). Also, self-rated life-change score through work (-3 to 3) was evaluated by three items, i.e.) changes in (1) the number of friends through work, (2) social interests and (3) the quantity of conversation with others (1 = increase, 0 = no change, and -1 = decrease). RESULTS: The factors associated with "Ikigai" for total subjects were the number of rooms in one's residence, annual income, healthy life style score (Breslow), the number of working days through SHRC, satisfaction with one's life history and life-change sore through work. The multivariable odds ratio (95% CI) of having "Ikigai" was 1.9 (1.1-3.3) for persons with no change in life thorough work compared with subjects with a score of < or = -1. Moreover, the multivariable odds ratios were 3.5 (1.9-6.6) for a life-change score = 1, 3.1 (1.7-5.7) for a score = 2 and 7.8 (4.0-15.2) for a score = 3 compared with persons with a score of < or = -1. For male subjects, other factors associated with having "Ikigai" were the number of rooms in their residence, annual income, the number of working days through SHRC, subjective assessment of health condition, and degree of satisfaction with their life history. For female, the corresponding factors were the presence of a spouse and degree of satisfaction with their life history. CONCLUSION: Scores for life-changes through work were associated with a higher prevalence of having "Ikigai" for both male and female. For male, "Ikigai" tended to be associated with physical condition and socioeconomic factors such as the size of their residence or annual income, while for female, family relations such as having spouse and psychological factors such as satisfaction with one's life history were significant factors. In spite of the design limitations of this study, it is possible to conclude that the recognition of life change through obtaining work may enhance "Ikigai" among people who wish to engage in productive activities in their later stages of life for both male and female. SHRC has a potential to provide resources for fulfilling one's "Ikigai" through supporting working opportunities to realize life changes for both elder male and female.

Relationship between self-assessed masticatory disability and 9-year mortality in a cohort of community-residing elderly people.

OBJECTIVES: To examine the relationship between self-assessed masticatory disability and mortality. DESIGN: Prospective. SETTING: Community based. PARTICIPANTS: Total of 1,405 randomly selected people aged 65 and older living in Settsu, Osaka Prefecture, in October 1992. MEASUREMENTS: Data on health status as indicated by disability scores, history of health management, self-assessed masticatory ability, and psychosocial conditions were collected by means of interviews during home visits at the time of enrollment. Nine-year follow-up was completed for 1,245 (88.6%; 398 deceased and 847 alive). RESULTS: Self-assessed masticatory disability was significantly associated with being 75 and older, having overall disability, not using dental health checks or general health checks, not participating in social activities, not feeling that life is worth living (no ikigai), and finding relationships with people difficult. As for the association between self-assessed masticatory disability and mortality, the estimated survival rate for those with self-assessed masticatory disability was lower than that for those without for each group stratified by sex and age (65-74 and >or=75), and the equality of survival curves according to self-assessed masticatory disability was significant for each group. After controlling for potential predictors of mortality, self-assessed masticatory disability remained as a significant predictor of mortality (adjusted hazard ratio=1.63, 95% confidence interval=1.30-2.03, P<.001). CONCLUSION: These results indicate that self-assessed masticatory disability may be associated with a greater risk of mortality in community-residing elderly people.

Metabolic syndrome and risk of isolated ST-T abnormalities and type 2 diabetes in Japanese male office workers.

Using a modified National Cholesterol Education Program (NCEP) definition of the metabolic syndrome (MS) with body mass index instead of waist circumference, we examined the associations of the MS with the risk of developing ST-T abnormalities in 3405 Japanese men aged 35-59 yr who did not have a history of cardiovascular disease or ST-T abnormalities. Of 3405 participants, 3166 men without type 2 diabetes (as diagnosed with the revised criteria of American Diabetes Association) also constituted a non-diabetic cohort. Examinations including electrocardiogram and fasting plasma glucose were repeated annually for 7 subsequent years. The subjects were classified as having ST-T abnormalities or type 2 diabetes when evidence of either of these disorders was found during at least 2 consecutive annual examinations. After adjustment for potential risk factors, the relative risks of ST-T abnormalities were 1.0 (referent), 2.66, 3.07, 4.27, and 8.40 for the presence of 0, 1, 2, 3, and > or =24 components of the MS, respectively (P for trend <0.001). The corresponding results for the risk of type 2 diabetes were 1.0 (referent), 3.49, 7.45, 15.00, and 24.04 (P for trend <0.001). The estimated incident rates for men in the low-WBC count (<7.3 x 10(9) cells/L)/no MS, high-WBC count (> or =7.3 x 10(9) cells/L)/no MS, low-WBC count/yes MS, and high-WBC count/yes MS were 3.4%, 4.6%, 7.4%, and 13.1% for ST-T abnormalities, respectively and were 3.6%, 7.1%, 18.0%, and 27.2% for type 2 diabetes, respectively. The respective multivariate-adjusted relative risks were 1.0 (referent), 1.26, 2.07, and 3.45 for ST-T abnormalities and were 1.0 (referent), 1.75, 5.14, and 6.90 for type 2 diabetes. A modified NCEP MS definition predicts ST-T abnormalities and type 2 diabetes. WBC count adds clinically important information to new-onset ST-T abnormalities and type 2 diabetes.

Cigarette smoking and the risk of the metabolic syndrome in middle-aged Japanese male office workers.

To examine the association between cigarette smoking and the risk of the metabolic syndrome (MS), 3649 Japanese male office workers aged 35-59 yr who did not have a history of cardiovascular disease were enrolled in this study. 2994 men without the MS at entry were followed up over a 7-yr period. A modified National Cholesterol Education Program definition with body mass index instead of waist circumference was used for the MS. With adjustment for age, family history of diabetes, alcohol intake, and regular physical activity, the odds ratios of the MS were 1.0 (referent), 1.30 (95% confidence interval (CI), 1.00-1.68), 1.07 (95% CI, 0.82-1.39), 1.17 (95% CI, 0.88-1.56), and 1.66 (95% CI, 1.24-2.20) for never smokers, ex-smokers, and those who smoked 1-20 cigarettes/d, 21-30 cigarettes/d, and > or =31 cigarettes/d, respectively (P for trend for current smokers only =0.006). As for the risk of developing the MS, the respective multivariate-adjusted hazard ratios of developing the MS were 1.0 (referent), 1.43 (95% CI, 1.14-1.79), 1.14 (95% CI, 0.91-1.44), 1.45 (95% CI, 1.14-1.84), and 1.59 (95% CI, 1.24-2.05) (P for trend for current smokers only =0.001). Among men without the MS at entry, body weight gain over 7 yr, compared with never smokers, was significantly higher in smokers who quit smoking. It is important for the prevention of the MS not only to quit smoking but also to prevent weight gain after smoking cessation.

Components of the metabolic syndrome as predictors of cardiovascular disease and type 2 diabetes in middle-aged Japanese men.

To determine whether the clustered features of the metabolic syndrome precede the 7 year incidence of cardiovascular disease (CVD) and type 2 diabetes, we examined 6182 Japanese male office workers aged 35-59 years without any history of CVD. The 5588 subjects without type 2 diabetes also constituted the nondiabetic cohort, and were re-examined over seven successive years. Components of the metabolic syndrome included glycemic disorder (type 2 diabetes for the risk of CVD and impaired fasting glucose for the risk of type 2 diabetes), systemic obesity, hypertension, dyslipidemia, proteinuria, and elevated white blood cell (WBC) count. After controlling for age, family history of diabetes, alcohol intake, and cigarette smoking, the multivariate-adjusted relative risk of incidence of CVD compared with absence of components was 3.18, 3.48, 12.55, and 14.15 (P for trend <0.001), for the presence of 1,2,3, and > or =4 components, respectively. The corresponding relative risks of incidence of type 2 diabetes were 1.92, 4.36, 6.44, and 15.08 (P for trend <0.001). In both non-smokers and current smokers, the multivariate-adjusted relative risks of incidence of CVD and type 2 diabetes increased as the number of components increased (P for trend <0.001 for all). Our findings indicate that clustered features of the metabolic syndrome are closely associated with development of CVD and type 2 diabetes in middle-aged Japanese.

[Factors promoting follow-up services after medical examinations by municipal governments].

OBJECTIVE: All Japanese municipal governments have a responsibility to conduct a medical examination for their residents aged 40 or more under the Health Services for the Elderly Act since 1984. According to the results of the medical examination, municipal governments should give appropriate follow up services to all users. The objective of this study was to find the factors promoting follow up services after medical examinations conducted by municipal governments. SUBJECTS AND METHODS: Mailed questionnaire surveys on follow up services after medical examination were sent out to all 3,255 municipal governments in Japan. The 2,447 municipal governments that answered all items on the questionnaire were enrolled in this study. Follow-up services by municipal government for persons with abnormal findings at medical examinations included "Suggestion to have a more detailed examination", "Confirmation of having had a detailed examination", "Individual health consultation", and "Home visit for medical guidance". These follow-up services were analysed in terms of the number of public health nurses per population and whether a continuous data set was maintained for medical examinations. RESULTS: Follow-up services were conducted more frequently in municipalities that maintained continuous data sets of medical examination than those that did not. They were also carried out more frequently in municipalities with higher numbers of health visitors per population than in those with lower numbers. The percentage of municipal governments that maintained continuous data of medical examinations was higher among those that conducted group medical examinations than those that conducted individual medical examinations at local medical facilities. CONCLUSION: Follow-up services after medical examinations by municipal governments showed a significant relationship with maintenance of a continuous data set of medical examinations and the number of public health nurses.

[Relationship between utilization of health notebooks and the elderly population rate among Japanese municipal governments].

OBJECTIVE: Health conditions are changing rapidly in aging societies and an essential health service by municipal governments is to promote the utilization of health notebooks in support of the health of individuals. The objective of this study was to clarify the relationship between utilization of health notebooks and rates for elderly among Japanese municipal governments. SUBJECTS AND METHODS: Questionnaires on the utilization of health notebooks were mailed to all 3,255 municipal governments in Japan. The 2,445 that filled in all items on the questionnaire were enrolled in this study. Questions concerned opportunities for utilizing health notebooks when residents received health education/guidance, health examinations, home visits, or welfare service. If they answered "Frequent use" for these opportunities, one point was given. Furthermore, if they answered that they filled in the results of residents' health examination into health notebooks, one point was given. If a municipal government got 4 points or more, this municipality was classified as "health notebooks frequently used". RESULTS: The percentage of municipalities defined as "health notebooks frequently used" was higher among municipal governments with a high rate of elderly residents than with a lower rate. The odds ratio for being classified as "health notebooks frequently used" was higher among municipal government with high rates for the elderly and public health nurses per elderly person than with low rates. CONCLUSION: With increase in the percentage of elderly residents, municipal governments need to promote their health services in support of residents' health. To improve the utilization of health notebooks, municipalities should increase the number of public health nurses.

Multiple risk factor clustering and risk of hypertension in Japanese male office workers.

Major risk factors associated with hypertension (a family history of hypertension, obesity, diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, hyperuricemia, and increased white blood cell counts) were assessed in 5275 Japanese male office workers aged 23-59 years. After controlling for potential risk factors of hypertension, the odds ratio of hypertension compared with the absence of risk factors was 1.91, 2.65, 3.88, 6.54, and 8.18 for the presence of 1, 2, 3, 4, and > or = 5 risk factors, respectively (P for trend < 0.001). Systolic and diastolic blood pressure levels also increased in a dose-dependent manner as the number of risk factors increased. Among men not taking antihypertensive medication, the adjusted mean differences in systolic and diastolic blood pressures (mmHg) were 11.2 and 9.2 between men with the presence of > or = 5 risk factors and men without risk factors, respectively. These results indicate that the accumulation of risk factors is highly associated with the increased risk of hypertension in Japanese men.

Associations between white blood cell count and features of the metabolic syndrome in Japanese male office workers.

We assessed the association of white blood cell (WBC) count with different components of the metabolic syndrome (MS) in 5275 Japanese male office workers aged 23-59 years. There was a significantly crude correlation between WBC count and body mass index, systolic and diastolic blood pressures, total cholesterol, high-density lipoprotein cholesterol (negative), triglycerides, fasting plasma glucose, and uric acid (all P<0.001). After controlling for potential confounding factors, the adjusted means of WBC count were significantly higher in subjects with each feature of the MS (obesity, hypertension, hypercholesterolemia, low high-density lipoprotein cholesterol levels, hypertriglyceridemia, high fasting plasma glucose levels, and hyperuricemia) (all P<0.005). The adjusted WBC count increments in subjects with 1, 2, 3, 4, and > or = 5 features of the MS were 0.28, 0.45, 0.68, 0.76, and 1.40 x 10(9) cells/l, respectively, compared with the subjects without features of the MS (P for trend<0.001). The adjusted means of WBC count increased significantly with the increasing number of features of the MS in both non-smokers and smokers (both P<0.001). These data indicate a strong association between WBC count and a number of disorders characterizing the MS independent of cigarette smoking among Japanese men.

[Tuberculosis control and strategy as an urban problem].

Tuberculosis is always an urban problem. There are differences in the severity of pulmonary tuberculosis in relation to socio-economic groups. The percentages of cases shown to be positive by smear microscopy of acid-fast bacilli in their sputum specimens and of cases with cavitary lesions in the lungs were high for the lower socio-economic group. The percentage of cases having had chest X-ray examination within the preceding year was low for the lower socioeconomic group. The Osaka metropolitan area consists of many prefectures and cities. Osaka City is in the center of this great metropolis. Registered cases of each zone had statistically differences about social characteristics. This result was thought to reflect the population of each zone. Cooperative common political will against tuberculosis in this area is needed to promote tuberculosis control. We analyzed the incidence rate in Osaka City in five-year from 1978 to 1997. Until the first half of 1980, the tuberculosis incidence rate in Osaka City had been dropping every year, but the rate of decline has been slowed substantially or even stopped since 1983. The slowdown in the reduction of the tuberculosis incidence rate has occurred not in all wards, but in a few wards and it is a typical phenomenon of the middle-aged in those wards. Such tuberculosis among employees in an insecure position has a growing urban social problem. It is important to establish the cooperation between medical facilities and public health centers within the territory of tuberculosis hospitals in an urban area. The sources of tuberculosis infection in an urban area are quite diverse and complicated. We shall utilize a molecular epidemiologic analysis of Mycobacterium tuberculosis.
