Controlled trial of worksite health education through face-to-face counseling vs. e-mail on drinking behavior modification.

This study examined the effectiveness of a traditional face-to-face health education and e-mail health education on alcohol usage among male workers in comparison with a control group. Male workers at a manufacturing plant (N=36) who had abnormal serum gamma-GTP were stratified by age and job types, then randomized into three groups: face-to-face education, e-mail education, and the control. The subjects were assessed on their knowledge about and attitude towards drinking, reported alcohol consumption, and serum gamma-GTP before the start of education and 2 months later after comparison of the education. Paired t-test and repeated ANOVA were conducted to test the significance of changes pre and post the intervention and across groups. In the face-to-face group, knowledge (p=0.001), attitude (p=0.026), alcohol consumption (p=0.003) and serum gamma-GTP showed significant improvement. In the e-mail group, only alcohol consumption showed marginal improvement (p=0.077). In the control group, no variables remarkably changed. These results indicate that the face-to-face health education was more effective than the e-mail program. We discuss why the face-to-face approach was superior to the e-mail approach in this study by referring to self-monitoring, goal setting processes and timely feedback. We concluded that further studies are warranted to identify the effect of health education using e-mails and other network tools in consideration of the above three factors.

[A survey of subjective symptoms and life-style in junior high school students].

PURPOSE: A questionnaire survey was conducted to examine a relationship between indefinite complaints and life styles in junior high school students and to apply the results to life guidance. METHODS: Twenty nine public junior high schools were selected by random sampling of 13 cities and 3 towns in Kanagawa Prefecture. A self-reported questionnaire was supplied to all subjects, containing 100 life-style related items, including a simplified CMI (Cornel Medical Index) questionnaire. RESULTS: The number of students who were evaluated as "point medical examination" based on physical symptoms of CMI and "disorder" based on the mental and physical symptom increased with the grade for both males and females. The students who reported "the life rhythm was always irregular" tended to be in the group evaluated as "disorder" or "point medical examination". The life rhythm was related to bedtime, sleeping hours and eating habits. It was observed that the students whose daily habits were always irregular had late bedtime, short sleeping hours and an irregular eating habit. As a result of the quantification method for the second type of analysis, it was found that sleeping time was the most related factor to the life rhythm. Furthermore 90% and more of students reported they did not consider nutritional balance with regard to their eating habits. CONCLUSION: It was suggested that those students who had irregular life rhythm needed sufficient sleep and nutrition guidance to maintain their health.

[A study on preventive effects of mite allergens by specially-fabricated futons with anti-mite treatments].

BACKGROUND: The purpose of this study was to investigate effects of specially-fabricated futons (beds) with anti-mite treatments on reductions of mite allergens (Der p.1 and Der f.1) and serum IgE antibodies against Dp (Dermatophagoides pteronyssinus), Df (Dermatophagoides farinae) and house dust1. METHODS: The futons made by microfibers (Madoromi: M) and phenolic polymer grafted microfine fibers (Madoromi+ALLER BUSTER: M+A) were used. Three groups of student and nurse subjects were asked to use general woolen cotton futons, and the (M) and (M+A) futons for 11 months, respectively. RESULTS: After the 11 months, the ratios of Der p.1+f.1 allergens in the futons (M) and (M+A) to those in the control futon were 1/3.8 and 1/42.0, respectively, on average. The prevalence of serum IgE antibodies against Dp, Df and house dust1 was found to decrease from 46.7 to 6.7% for the group using the (M+A) futon. CONCLUSION: These results suggested the specially-fabricated futons with anti-mite treatments could effectively reduce mite allergens compared to those made from woolen cotton.

[Analysis of factors affecting breakfast skipping by male students undergoing hard training for sports].

PURPOSE: The purpose of this survey was to find factors affecting breakfast skip rates for male students participating in sports, and to determine how to improve their nutrition. METHODS: The survey was conducted on 86 male students (58 who played sports and 28 who did not). A questionnaire was supplied to all, containing questions concerning daily food eating behavior. The student's answers were evaluated according to the guidelines of the Ministry of Health and Welfare. In addition, blood pressure, body mass index, and serum levels of uric acid, triglycerides and ferritin were measured in all subjects. RESULTS: The breakfast skip rate was 36% for the sports club affiliation group, and 46.4% for the non-affiliation group. Students who were not supplied with meals from their mothers or dormitory food service had more irregular meal times, skipped breakfast more, and drank less milk and miso soup often than the students supplied with meals. Students playing sports, but not supplied with meals, had a lower evaluation regarding eating habits and higher serum levels of serum uric acid and ferritin, compared to the students supplied with meals. CONCLUSIONS: The eating habits of male students are affected by whether they receive meals or not. It is considered that the higher levels of serum uric acid and ferritin in the students not supplied with meals is due to their irregular eating habits and heavy exercise. It is suggested that nutritional guidance is needed for such students.

Measurement of atmospheric NO2 concentrations in Antarctica with NO2 filter badge and tube.

Nitrogen dioxide (NO2) levels in Antarctica were monitored to determine background levels and distribution profile. The NO2 levels were higher than those reported from tropical remote areas. The NO2 concentrations gradually increased proceeding from the edge of the continent to the polar region, suggesting global pollutant transportation. To avoid artificial contamination of the data, a sled was used because motor vehicles discharge high levels of NO2. NO2 tubes and filter badges were selected as monitoring devices because of their convenience of transportation in Antarctica. They are small in size, light and easy-to-handle, and usually employed in personal NO2 exposure measurements. Because of severe Antarctica climate, the devices needed to be protected from the bitter cold. For that purpose, we designed an insulation container to shield the devices. The fixed NO2 monitoring site was Patriot Hill, located on the coast of the Weddell Sea. We also measured NO2 concentration along the expedition route from the fixed site to the South Pole, along with the 80 degrees west longitude. The survey periods were during November 1992 and January 1993. NO2 concentrations in Antarctica ranged from 1.0 to 2.8 ppb, which were relatively higher than previously reported background concentrations. The NO2 concentrations increased when nearing to the South Pole, supporting the theory that atmospheric circulation converges in the polar regions. This indicated that air pollutants discharged in populated regions were widely spread to isolated areas, like the South Pole.
