Corrigendum*: Effects of Computer-based Stress Management Training on Psychological Well-being and Work Performance in Japanese Employees: A Cluster Randomized Controlled Trial.

In Table 2, Mean and SD were opposite between the intervention group and the wait-list control group. In Table 3, there was a mistake in the annotation: the number of the intervention group was 142. The corrected Table 2 and Table 3 are presented below. We apologize for any inconvenience that this may have caused. *Important errors made by the author(s).

Effects of computer-based stress management training on psychological well-being and work performance in japanese employees: a cluster randomized controlled trial.

This study evaluated the effectiveness of a computer-based stress management training (SMT) program in improving employees' psychological well-being and work performance. A total of 12 work units (N=263) were randomly assigned to either an intervention group (8 work units, n=142) or to a wait-list control group (4 work units, n=121). All participants were requested to answer online questionnaires assessing psychological well-being as a primary outcome, and coping style, social support, and knowledge about stress management as secondary outcomes at baseline (T0), immediately after the intervention (T1), and 2 months after the intervention (T2). The group × time interaction was tested using a mixed-model repeated measures ANOVA. Results showed a group × time interaction for "knowledge about stress management" in the entire sample. Among participants who had more than 3 d of training, a significant group × time interaction was observed for "problem-solving" and "avoidance and suppression" as well as "knowledge about stress management." Our computer-based stress management program was effective for improving knowledge about stress management. It was also effective for improving coping skills in instances where participants had enough time (at least 3 d) to complete all sessions.

Body mass index, blood pressure, and glucose and lipid metabolism among permanent and fixed-term workers in the manufacturing industry: a cross-sectional study.

BACKGROUND: Temporary employment, a precarious form of employment, is recognized as social determinant of poor health. However, evidence supporting precarious employment as a risk factor for health is mainly obtained from subjective data. Studies using objective clinical measurement data in the assessment of health status are limited. This study compared body mass index (BMI), lipid and glucose metabolism, and health-related lifestyle factors between permanent workers and fixed-term workers employed in the manufacturing industry. METHODS: Data of 1,701 male manufacturing industry workers <50 years old in Japan were collected and analyzed. Anthropometric data were BMI, calculated using measured height and weight of study participants, and blood pressure. For lipid metabolism, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride levels were determined. For glucose metabolism, fasting plasma glucose and hemoglobin A1c (HbA1c) levels were measured. Multiple regression analysis adjusted for age and lifestyle factors was performed. RESULTS: BMI was significantly higher in permanent workers (22.9 kg/m2) compared with fixed-term workers (22.4 kg/m2). The leaner population (BMI < 18.5) was greater among fixed-term workers (8.3%) compared with permanent workers (4.0%), whereas the overweight population (BMI ≥ 25.0) was greater among permanent workers (21.4%) compared with fixed-term workers (18.1%). Although fixed-term workers tended not to be overweight, regression analysis adjusted for age and lifestyle factors suggested that fixed-term employment was significantly associated with higher blood pressure (systolic ß = 2.120, diastolic ß = 2.793), triglyceride (ß = 11.147), fasting blood glucose (ß = 2.218), and HbA1c (ß = 0.107) compared with permanent workers (all p < 0.01). CONCLUSIONS: Fixed-term workers showed more health risks, such as poorer blood pressure and lipid and glucose metabolism, even when adjusted for age and lifestyle variables, although BMI of fixed-term workers were lower than permanent workers. Precarious work might contribute to a deteriorating health status even among less overweight populations.

Risk factors for new-onset atrial fibrillation during routine medical checkups of Japanese male workers.

The current study aimed to identify risk factors for atrial fibrillation (AF) detected during routine medical checkups of male workers in Japan. A nested case-control study was conducted using retrospective data from January 1998 to December 2006 collected at a hospital in Ishikawa Prefecture. Cases were those first diagnosed with AF with no record of AF events during the preceding 3 years. For each case, 2 controls were matched for age and time of medical checkup, randomly selected from among those who had not been diagnosed with AF during the same 3 years. Logistic regression was used to identify risk factors in the 3 years prior for new-onset AF. Sixty-nine cases and 138 controls were recruited; their average ages were 57.6 (SD 6.7) and 57.4 years (SD 6.7), respectively. In the logistic models, new-onset AF was associated with systolic blood pressure and drinking habits in the 3 years prior.
