In order to elucidate the effcts of newcomers' support network structure at workplace on the mental health in a corporate setting, we performed a longitudinal study of 890 men and women scheduled to graduate from four universities in the greater Tokyo area who had been provisionally accepted to begin work in 2003. Surveys were distributed and collected at three time points: just Prior to entering the workplace (T1), three months after entering the workplace (T2), and six months after entering the workplace (T3) . We performed longitudinal data analysis to investigate how patterns of network relationships affected mental health (psychosomatic symptoms, depression, self-esteem, work motivation) comparing good mental health group with poor mental health group at T3. Both information network and friendship network were assessed on the survey and consisted of the network parameters of Size, Status, Frequency, and Intimacy. Size and Frequency of the informational networks related positively to self-esteem and work motivation. Also, Intimacy related positively to all mental health indicators. All parameters of friendship networks related positively to self-esteem and wotk motivation. Our results indicated that it was important to commumicate with superiors frequently, and have intimate co-workers, for newcomer's mental health.

As one of the capability indices which participates in the modification of health related behavior, Perceived Health Competence Scale (PHCS) attracts attention. It aims at examining the relevance of the between PHCS and the socio-economic status in this research.
Interviews were sought with 3, 000 randomly selected Japanese individuals using a two-step stratified method. Valid PHCS responses were obtained from 1, 910 individuals, yielding a 63.7% response rate. This research examined the educational history of parents and self, the self occupation, and the self income as socioeconomic status. First, the PHCS score distribution was shown according to sex. Next, multiple linear regression analysis which made PHCS dependent variable and made the socioeconomic status independent variable was carried out.
Consequently, in the male, it became clear that it is related to a high PHCS score with that the educational history of self is high, a retired employee, and a white-collar worker. However, relation was not seen between the PHCS score and the income. On the other hand, in the women, it became clear that it relates to a high PHCS score that a mother's educational history is high, that they are professionals and self-employment, and that it is not a low income.
From now on, about examination of a socioeconomic disparity, longitudinal research will be required. On the other hand, since R square is only less than 10%, PHC may be formed a-posteriors. Examination about development of the intervention program which will lead to maintenance improvement of PHC from now on is also desired.

The purpose of this study is to investigate the basic data for preventive education of lifestyle-related diseases at public sports facilities. We reviewed a factor structure with items from nine kinds of living habits including, psychological stress, physique index, work and so on. We distributed a questionnaire to 2, 104 (733 males and 1, 371 females, 16 to 79 years old) users at public sports facilities. We used a principal component analyses to conduct our research. The following findings were obtained.
Eating only one or two meals a day, lack of a balance diet and smoking are the main risk factors for lifestyle-related diseases in the younger generation. The intake of sweets and snacks are the main risk factors for lifestyle-related diseases in females. In case of elderly males, lack of exercise in their free time, an increase in psychological stress, rise in the Body Mass Index (BMI), and an increase in alcohol intake.
These findings suggest that it is useful to understand these factors concerning living habits that are based on age and sex in order to prevent lifestyle-related diseases. In this regard a causal linkage between these factors and age groups cannot be confirmed.
