JOURNAL FREE ACCESSThe relationship between lifestyle and bone metabolism was studied. Hyashi's Quantification III method was used for analysis of data concerning lifestyle and bone metabolism for 60 healthy women aged 19-20 years old. The major results were as follows:1. The lifestyle features associated with very good bone metabolism were walking for less than 1.5h/day, exercise, a some-what poor diet, and low energy input.2. The lifestyle features associated with good bone metabolism were walking for more than 2h/day, good diet, and high energy input.3. The lifestyle features associated with increases in bone resorption and poor bone stiffnes were lack of exercise, a poor diet, and low energy input.4. The lifestyle features associated with low bone stiffnes were insufficient-walking, and staying continuously in one position. These findings show that there is a relationship between problems in lifestyle and diseases of bone, and suggest that assessment of individuals and long-term care are imporatant for bone health in young women.View full abstractDownload PDF (1085K) -

JOURNAL FREE ACCESSThe purpose of this study was to examine the relationship between bone mineral density (BMD) and past dietary habits of middle-aged and elderly women who were hig-risk population of osteoporosis. We examined dietary habits of 713 women aged 50 years and over who underwent a check-up for osteoporosis at two public health centers in Ibaraki Prefecture. Items examined were frequency of intake of milk, cheese, yogurt, small fish, eggs, cooked beans, tofu, natto, vegetables and seaweed in their 20's, 30's and 40's. GS/D values were used as the indicator of BMD. Women with GS/D values less than 2.3 were designated as the low BMD group, and those with GS/D values more than 2.3 were designated as the control group. The differences in the intake frequencies of the aforementioned foods by the two groups were evaluated by chi-square tests. The results of our study showed that each proportion of people who consumed milk, small fish or seaweed every day in their 30's and 40's, and also in their 20's for the case of milk, was higher in the control group significantly. It was also indicated that each proportion of people who consumed tofu or vegetable more than three times in a week was higher in the control group. Those who consumed little of each kind of food little were seen in the low BMD group. It was concluded that there was a relationship between BMD and dietary habits related to calcium intake.View full abstractDownload PDF (2935K) -

JOURNAL FREE ACCESSThe modern Japanese society has become a very difficult environment for adolescents in which to maintain their optimal physical and mental health. Lifestyle in particular is said to reflect not only health, but also psychological wellbeing including the level of anxiety in adolescents. To investigate the relationship between lifestyle and anxiety in adolescent females, 475 junior high school students at a private women's school in Kanagawa Prefecture participated in this study in April, 1999. A questionnaire was distributed, and physical measurements were taken for all subjects. The percentage of body fat was also measured using a Tanita TBF-310 machine. In addition, the Children's Manifest Anxiety Scale (CMAS), Japanese Version, was used for assessing the anxiety level of students. The data was analyzed with SPSS 9.0 for Windows, and 413 subjects (mean age =13.57 years) with valid and reliable CMAS scores were selected for analyses. As a result, there were significant differences in menarche rate, Body Mass Index (BMI), and the percentage of body fat by grade level. However, no difference in CMAS score by grade was observed. Fewer hours of sleep per night, having no late meal, eating breakfast alone, and having a large appetite were increased as the grade level increased. In addition, subjects were divided into 3 groups (low, moderate, and high anxiety) by the CMAS total score. The high anxiety group reported symptoms of diarrhea more than other groups. In terms of health practices and eating habits, difficulty in waking up and sleeping well, few hours of sleep per night, getting up at irregular times, skipping breakfast, and not enjoying meals were associated with the high anxiety group. Few hours of sleep, having no late meal, and skipping breakfast were also seen in students with high BMI. Multiple regression analyses revealed that the length of sleep per night, presence of diarrhea symptoms, and difficulty in waking up were predictors of the total CMAS score of subjects. In summary, the level of anxiety in adolescent girls showed a significant correlation with unhealthy lifestyles including health practices and eating habits. These findings suggested that an appropriate health education program for a healthy lifestyle could help maintain optimal mental health in adolescent females.View full abstractDownload PDF (1289K)
