Predictors of Japanese Workers' Motivation to Use the Results of Worksite Health Checkups in Their Daily Health Management

Comparative study on the activities of part-time occupational physicians in Japan between 2008 and 2016: effects of the stress-check program

The Ministry of Health, Labor, and Welfare of Japan recommends that an occupational physician (OP) play an important role in implementing the stress-check program since 2015. This study aimed to compare the activities and encountered difficulties of Japanese part-time OPs in 2008 and 2016, and to investigate the effects of the stress-check program. Questionnaires were sent via mail to 946 part-time OPs in Kyoto prefecture in 2016. Completed questionnaires were returned by 181 OPs who were private practitioners or physicians in hospitals, and served as OPs on a part-time basis. In 2016, OPs utilized long hours for activities related to general health examination and to stress-check. Hours for specific health examination, health and hygiene education, health promotion activity, development of a comfortable workplace, and guidance of workers on sick leave reduced from 2008 to 2016. A total of 62% OPs frequently encountered difficulties in the stress-check-related activities in 2016. Many OPs also reported difficulties in the mental health care and the prevention of health hazard due to overwork both in 2008 and 2016. Enforcement of the stress-check program in 2015 changed the activities of part-time OPs in Japan. OPs should be given opportunities to gain more information in this area.

Age Differences in Health Behavior and Weight Changes in Japanese Workers: 1-Year Follow-Up Study

OBJECTIVE

To examine 1-year changes in stage of health behavior change and its associations with changes in health behavior and weight in a working population cohort.

METHODS

Using annual health examination data, 57,431 eligible Japanese workers aged 18 to 64 years were examined for their 1-year changes in stage of change, eating and exercise habits, and weight.

RESULTS

The stages of change became polarized into the precontemplation and the action/maintenance (ie, post-action) and became stabilized with increasing age. The 1-year change in stage of change was accompanied by changes in eating and exercise habits and weight.

CONCLUSIONS

The age-dependent tendency towards bipolarization and stabilization of stages of change suggested that workplace health promotion interventions for facilitating health behavior changes should be started at younger ages.

The importance of internal health beliefs for employees' participation in health promotion programs

OBJECTIVE

To investigate associations between employees' health locus of control (HLOC) and self-perceived health, health behaviors, and participation in health promotion programs (HPPs) and the mediating effect of self-perceived health and health behaviors on the relation between HLOC and participation.

METHOD

Between 2010 and 2012, a six-month longitudinal study was conducted among 691 Dutch employees. Using questionnaires, information was collected on health behaviors, self-perceived health, HLOC, and intention to participate at baseline. Actual participation was assessed at follow-up. Logistic regression analyses were used to study associations between HLOC and self-perceived health, health behaviors, and participation, and to examine whether associations between HLOC and participation were mediated by self-perceived health and health behaviors.

RESULTS

Higher internal HLOC was associated with sufficient physical activity (moderate: OR:1.04, 95%CI:1.00-1.08; vigorous: OR:1.05, 95%CI:1.01-1.10) and fruit and vegetable intake (OR:1.05, 95%CI:1.01-1.09), a good self-perceived health (OR:1.20, 95%CI:1.11-1.30), a positive intention towards participation (OR:1.05, 95%CI:1.00-1.09), and actual participation (OR:1.06, 95%CI:1.00-1.13). Self-perceived health or health behaviors did not mediate associations between HLOC and participation.

CONCLUSION

Employees with a higher internal HLOC behaved healthier and were more likely to participate in HPPs, irrespectively of their health. Increasing internal HLOC seems a promising avenue for improving employees' health and participation in HPPs.

Activities of private clinic- or hospital-based occupational physicians in Japan

The present study was initiated to examine the activities of private clinic- or hospital-based occupational physicians (OPs) and to identify difficulties the OPs encountered in their occupational health service (OHS). A questionnaire was sent by mail to 557 OPs in Kyoto prefecture, Japan. Effective answers were obtained from 86 OPs who were private practitioners or physicians in hospitals and served as OPs on a part-time basis. Considering 3 h as a unit, a majority (92%) served <1 to 2 units/month. The leading fields of OHS provided by the OPs were general health examination and its follow-up, prevention of overwork, and mental health care, as well as support of workers on sick leave to return to work. OPs wished to allocate more time for maintenance and management of work and the work environment, mental health care, work area rounding, and attendance at the safety and health committee meetings. Difficulties were encountered most often in the management of mental ill health and overwork, and support of employees' return to work. Many OPs also reported difficulties with industrial hygiene-related issues such as risk assessment, and maintenance and management of work and the work environment. The present survey identified difficulties that were frequently encountered by private clinic- and hospital-based OPs in their practice of OHS; these include issues on mental health, overwork and industrial hygiene. The needs to offering OPs specific opportunities to gain information and skills in these areas are stressed.

A lifestyle to prevent or combat the metabolic syndrome among Japanese workers: analyses using the health belief model and the multidimensional health locus of control

We investigated the predictors significantly associated with a lifestyle to prevent or combat the metabolic syndrome among Japanese workers. We conducted an anonymous self-administered questionnaire survey and analyzed the resulting data using multiple linear regression analysis. The dependent variable was a lifestyle to prevent or combat the metabolic syndrome (7-point scale). Independent variables were: subjects' basic attributes (age, gender, blue or white collar worker, with or without a family physician), Multidimensional Health Locus of Control (7-point scale for each item), with or without the metabolic syndrome being pointed out or not by healthcare providers, and 4 items regarding the metabolic syndrome produced with reference to the Health Belief Model (7-point scale for each item). Those independent variables were all included in this model. The analysis shows the older workers, white-collar workers, and workers who had the metabolic syndrome pointed out by healthcare providers had appropriate lifestyles. Those with high scores in Powerful Others Health Locus of Control also had appropriate lifestyles. Those who realized that the metabolic syndrome was a life-threatening disease and who knew practical ways to prevent or combat the metabolic syndrome also had appropriate lifestyles. Our findings can be applied to various types of medical education regarding the metabolic syndrome.
