Objectives: This study was conducted to expand evidence-base for the effectiveness of lifestyle intervention programs to prevent the onset of diabetes and cardiovascular diseases. Methods: Seven intervention studies between 2006 and 2014 at Korea Association of Health Promotion were analyzed. All the studies were randomized controlled trials(RCTs) and included multi-component behavioral interventions. The participants of the programs were 2,172 adults with risk factors regarding metabolic syndrome criteria. The proportions of normalized participants were compared within and across the studies using odds ratio effect sizes. Results: The reductions in the prevalence of metabolic syndrome were from 49.6% to 65.1% in intervention groups, and from 38.7% to 52.3% in comparison groups. Significant differences in effectiveness between groups were found in two studies, one in 2006 with odds ratio of 1.69(p<0.01) and another in 2009 with odds ratio of 2.36(p<0.001). Proportions of normalized participants were higher in blood pressure(31.9% to 52.5% in the intervention groups and 23.0% to 43.3% in comparison groups) than other risk factors. Abdominal obesity showed weakest improvement after the intervention in both groups. Conclusions: Lifestyle modification program is an effective method to reduce diabetes and cardiovascular risks in adults by decreasing the prevalence of metabolic syndrome and its components.

Objective: The aim of this study is to review the literatures on the regulation, standard and guideline for the human vibration in Korea and other countries. Background: This review can be used to prevent various diseases caused by the human vibration as a basis for the development of the policy. Results: In Korea, the general employers' duties related to human vibration are set forth the Health Measures(Article 24) in the Occupational Safety and Health Act. And then an employer shall take measures to protect the health of the workers concerned by improving other working conditions relating to working hours for the vibration prevention measures referred to in Article 24 of the Act. The European Union adopted a Directive in 2002 on minimum requirements for the health and safety of workers exposed to vibration. New Regulations on Vibration at Work will be introduced in Great Britain on 2005 to implement the Directive. In the U.S., both ANSI and ACGIH adopted the ISO standard for measurement and suggested exposure action and limit values. In Japan, the Ministry of Labor decided that the vibration syndrome among operators of rock drills and riveters etc. could be included in an occupational disease(1947). In addition, ISO standard was based on proposals and draft documents of many countries such as U.K, Japan and European, etc. Conclusion: In Korea, Occupational Safety and Health Act prevent vibration to health, but do not include exposure limits. It is therefore important to consider the new duties regarding to vibration risks added to the general duties.

Purpose: The purpose of this study was to examine the relationship between the toothpaste squeezing methods and the amount of toothpaste that the daycare teachers apply for the children in order to prevent the overuse of fluoride-containing toothpaste among children, and to understand their educational experiences on oral health and their awareness of the right amount of toothpaste used. Methods: The subjects in this study were 87 teachers at 16 different daycare centers in the city of Sokcho, Gangwon Province. They were interviewed to find out whether they had ever received oral health education and whether they were cognizant of the right amount of toothpaste to be used. And a transverse technique and a pea-sized squeezing technique were selected to look for connections between their toothpaste squeezing methods and the amount of toothpaste used by them. Results: 89.7 percent of the daycare teachers investigated taught to preschoolers how to do toothbrushing after they took meals and had a snack. 36.8 percent of the daycare teachers had children squeeze toothpaste on their own. The amount of toothpaste applied by the daycare teachers at a time was 0.58ｇ. When they utilized two other squeezing methods, transverse technique and pea-sized squeezing technique, they used each 0.38 g (p<0.005) and 0.38 g (p=0.405) of toothpaste. Conclusion: To prevent children from being overly exposed to fluoride-containing toothpaste, daycare teachers should learn about the right amount of toothpaste to be used when oral health education is provided, and the transverse technique should be recommended to ensure the use of the proper amount of toothpaste.

Everyone is aware that air and environmental pollutants are harmful to health. Among them, indoor air quality directly affects physical health, such as respiratory rather than outdoor air. However, studies that have examined the correlation between environmental and health information have been conducted with public data targeting large cohorts, and studies with real-time data analysis are insufficient. Therefore, this research explores the research with an indoor air quality monitoring (AQM) system based on developing environmental detection sensors and the internet of things to collect, monitor, and analyze environmental and health data from various data sources in real-time. It explores the usage of wearable devices for health monitoring systems. In addition, the availability of big data and artificial intelligence analysis and prediction has increased, investigating algorithmic studies for accurate prediction of hazardous environments and health impacts. Regarding health effects, techniques to prevent respiratory and related diseases were reviewed.

Purpose: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. Methods: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. Results: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. Conclusion: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

Objectives: Objective of this study is to review briefly exposure characteristics, monitoring instruments and threshold limit values for extremely low frequency-magnetic field (ELF-MF) methods. This study was undertaken through brief literature review. We performed a literature search in PubMed to identify ELF-MF studies conducted in workplaces. Initial search keywords such as 'extremely low frequency-magnetic field (ELF-MF)' and 'electromagnetic fields (EMF)' combined or singly. We limited our review to occupational rather than general nonworkplace environmental exposures. Methods: The contents we reviewed: key industry and occupations generating ELF-MF, several direct-reading instruments monitoring ELF-MF and threshold limit values (TLV) preventing health effects may be caused by the exposure to ELF-MF. Results: The industries related to the generation and supply of electricity, electrolytic installations, welding, and induction heating and more were regarded as high ELF-MF exposure industries. All jobs handling or employed performed in power cable lines, electrical wiring, and electrical equipment are found to be exposed to ELF-MF. Threshold or ceiling limit, 1,000 µT, is established to prevent acute effects of exposure to low-frequency EMFs on the nervous system: the direct stimulation of nerve and muscle tissues and the induction of retinal phosphenes. The International Agency for Research on Cancer (IARC) has classified ELF-MF as possibly carcinogenic to humans chiefly based on epidemiological studies on childhood leukemia. However, a causal relationship between magnetic fields and several types of cancer including childhood leukemia has not been established nor has any other long-term effects. Risk management using precautionary measures, has been initiated by the US and EU to prevent chronic health effects related to ELF-MF exposure in workplaces. Conclusion: This study recommends the implementation of various measures such as theestablishment of occupational exposure limit values for ELF-MF and precautionary principle to prevent potential chronic occupational health effects may be caused by ELF-MF in Korea.
