Background: Epidemiological findings suggest that weight fluctuations are associated with unfavorable health outcomes compared with stable weight. However, the interrelationship between the weight cycling history and dieting status in a non-clinical male trial on the risk for bio-behavioral health is unclear. Objective: The purpose of this study was to examine the relation between weight cycling history as a result of intentional weight loss and bio-behavioral health in Japanese adult males. Method: A cross-sectional study was performed on a group of 146 Japanese working males (47.5±9.3 yr.). Each subject completed a series of self-reported questionnaires in which information about weight cycling history, current dieting practices, life-styles, and social background were assessed. Results of the physical check up were used to assess biological parameters. Self-reported weight cycling was defined as intentionally losing 10% of one's weight and regaining the lost weight. Results: Cyclers reported a significantly greater incidence of current dieting and recent weight gain compared with non-cyclers. Taking regular meals, eating breakfast everyday, and not eating snacks between meals every day were significantly less frequent among cyclers compared with non-cyclers after controlling for BMI. The adjusted odds ratio for AST abnormality was 5.46 (95%CI: 1.08 −27.67), ALT abnormality was 3.31 (95%CI: 1.24−8.78), and γ-GTP was 3.38 (95%CI: 1.07−10.67) among cyclers, compared with non-cyclers. Conclusion: These findings suggest that a history of weight cycling in men, regardless of current weight status, is associated with adverse bio-behavioral health. The risk for several liver enzyme abnormalities associated with weight cycling history was substantial, independent of relative body weight and lifestyle factors.

Background: Lung cancer screening by chest X-rays and/or cytological tests of sputum has been practiced for many years. Nonetheless the number of deaths from lung cancer was kept increasing all this while. We wanted to find a way to decrease the mortality from lung cancer by investigating the screening methods or lifestyle to prevent the lung cancer.
Methods: I. The detection rate of lung cancer was investigated according to each method of screening-helical CT, chest X-rays or sputum tests, from 1998 to 2000.
II. Seventy-nine cases of lung cancer detected by the screening carried from 1995 to 2000 at our institute were compared with control cases matched with respect to age, sex and seasons of screening.
Results: I. The detection rate by helical CT in 1998, 1999, and 2000 was 0.29%, 0.24%, and 0.19%, respectively, while the detection rate by chest X-rays was 0.01%, 0.02% and 0.2%. There was no detection of lung cancer by sputum tests in those three years.
II. The ingestion of vegetables was the only one statistical difference between the lung cancer group and the control group. A lesser ingestion of vegetables increased the risk for lung cancer.
Conclusions: The detection rate of lung cancer by helical CT is remarkably higher than chest X-rays or cytological tests of sputum. People who eat a lot of vegetables have a lesser chance to suffer from lung cancer.

High-quality terminal care cannot be given without good communication and understanding among patients, their family members and health as well as medical professionals.Recently, we have taken a questionnaire survey on new inpatients in our hospital to sound them out on their thinkings about hospital care, and examined the findings along with the validity of survey.Many respondents including those contracting either benign or malignant diseases wished to be keptposted on what they are really up against and to partake in the decision-making process before treatment plans are put into practice. The recent questionnaire survey has proved to be worthwhile as a tool to know the wishes of hospitalized patients and suggested an effective way to promote the practice of obtaining informed consent before specific test and therapautic procedure.
