Introduction This study intended to examine the effect of an eHealth self-management (eHSM) intervention on elderly Korean persons who live alone in a community. Methods A quasi-experimental study was designed, and a total of 64 elderly persons (intervention n = 31, control n = 33) with hypertension (a systolic blood pressure measurement of ≥140 and/or a diastolic blood pressure ≥90 mm Hg) or taking anti-hypertensive medication participated. The eHSM intervention consisted of a four-week, in-class educational phase, community-based eHealth monitoring, and monthly telephone counselling for 24 weeks. Results The primary outcome measurement of the study was BP, and secondary outcomes included psycho-behavioural variables. Specifically, the systolic BP among intervention group participants was 133.9 mm Hg at baseline and 122.5 mm Hg after 24 weeks of follow-up. Participants in the intervention group showed greater improvement in self-efficacy, self-care behaviour, and social support than did participants in the control group 24 weeks post-intervention. Discussion The results highlight the clinical efficacy of an eHSM intervention composed of a four-week education program, self-monitoring, and follow-up counselling. The eHSM intervention should be expanded to include community-dwelling elderly persons with hypertension to improve the self-management of hypertension and control of blood pressure.
Korea needs national strategies to handle problems of Small Scale Enterprises (SSEs) systematically. Since 1993, the Korean government has begun to provide financial subsidy programs for Occupational Health Services (OHSs) in SSEs from Occupational Injury Prevention Fund. To identify the health care status in SSEs in Korea, 5,080 factories, which had participated in the Government-funded Subsidy Program in 1997, were surveyed. The overall morbidity of the workers in these SSEs was higher than the national average for both general and occupational diseases. Based on the health examinations for occupational disease of those workers exposed to occupational hazards such as noise, dust, or solvents, we could find the industry-specific occupational disease patterns. From this result, we would plan the targeted occupational health services to specific groups. In spite that the effectiveness of this program is not completely assessed, our results indicate that it is desirable for this program to be continued in Korea. In addition, this program may be a good model for rapidly developing countries.
Associations between several occupational characteristics and obesity are not fully elucidated in Korean working populations, especially in females. This study investigated associations between occupational characteristics and overweight/obesity among Korean women. Data on 2090 female workers (the mean age was 38.8 ± 0.2 years), extracted from Korean National Health and Nutrition Examination Surveys in 2010-2015, were analyzed and showed that 6.8% of subjects were underweight, 50.8% had normal weight, 20.1% were overweight, and 22.2% were individuals with obesity. Multiple regression analysis was performed to examine associations between occupational characteristics and overweight/obesity, after controlling for demographic, behavioral, and health-related characteristics. The reference group was normal weight. Working hours were strongly associated with overweight/obesity. The odds ratio (OR) of obesity in women who worked for ≥60 h per week was 2.68 (95% confidence interval: [CI] 2.13-3.36) compared with those who worked for <40 h. Night/shift workers were 1.21 times (95% confidence interval: [CI] 1.01-1.45) more likely to experience obesity than day or evening workers. In conclusion, obesity rates increase among female workers with longer working hours and those who work at night or in shifts. Occupational characteristics should be considered in the prevention of obesity among working women.
Increasing evidence indicates that nocturnal blood pressure level and/or loss of nocturnal blood pressure dips are sensitive markers of cardiovascular morbidity and mortality. Several studies have suggested that blunted heart rate variability and nocturnal decline in heart rate are also associated with target organ damage. These phenomena occur relatively commonly in patients with Parkinson disease (PD); however, few studies have assessed the consequences of these abnormalities in patients with PD. We investigated the influence of circadian changes in blood pressure and heart rate on white matter hyperintensities (WMHs) in patients with PD. The presence of nocturnal hypertension was associated with increased WMH score, and nighttime systolic pressure was closely related with white matter changes. Blunted heart rate variability and nocturnal decline in heart rate were also related to increasing WMH scores. The non-dipping phenomenon did not influence WMHs. These findings suggest that white matter changes are related to circadian autonomic dysfunction, particularly nocturnal hypertension in patients with PD. Therefore, it is important to monitor nocturnal blood pressure status, because modifying these circadian regulatory disturbances can be beneficial to protect against vascular brain damage in patients with PD.
