“…In this study, the results suggested that those with volleyball or basketball experience particularly in the senior high school years exhibited significantly high bone density compared with others. Omasu et al [8] stated that the amount of physical activity in the senior high school years had an impact on bone mass. As load is categorized as a qualitative issue and the amount of physical activity is categorized as a quantitative issue, both may have a significant impact on the growth period.…”

This survey was conducted with the aim of clarifying and providing guidance regarding correct lifestyle and exercise habits from adolescence in order to prevent the development of osteoporosis. The subjects included 195 Japanese adult females. We measured their calcaneal bone density by ultrasonography, the index of which was determined as SOS (Speed of Sound). We examined their physical characteristics, health conditions, amount of physical activity, exercise history, and eating habits, and then analyzed the relationship thereof with bone density. No significant correlation was found between height, weight, BMI (Body Mass Index), or body fat percentage and the SOS value. Moreover, the bone density among those with a history of exercise was high. Breaking it down, we obtained results such as the fact that exercise habits during the junior and senior high school years had a great impact on the acquisition of peak bone mass, although no relationship between exercise habits and bone density was found during the elementary school years. Furthermore, as the bone density of students who continued exercising in junior and senior high school indicated high values, continuity of exercise during the growth period (during puberty) is believed to have a great impact on peak bone mass. Upon investigating the content of meals including foods which have a positive impact on the bones, "bean and bean products" and "green and yellow vegetables" were found to be related to bone density. From the above, the effect that the lifestyle of young adult females had on bone density was partially clarified. In particular, one factor which had a strong relationship with current bone density was exercise history during the junior and senior high school periods. It was clarified that continuously engaging in exercise and placing strain on the bones during these periods lead to high bone density acquisition.

We studied the relationship between dieting and bone density among female college students and the current state thereof. Female college students are generally thin, with the time to giving birth and raising the next generation approaching. We expect the results of this study will be useful in improving health guidance. The subjects consisted of 124 female college students. Their average age was 21.4. The ultrasonic propagation velocity of the heel bone was measured as the bone density value. Body height, weight, and BMI (Body mass index) were also measured. Further, a multiple choice and short answer survey was conducted regarding their desire to be thin and dieting. Classifying the subjects by BMI, 16 students were underweight (13%), 102 students were of normal weight (84%), and 4 students were overweight (3%). 95% of those in the normal weight group had a desire to be thin, while 44% of the underweight group had a desire to be thin. Moreover, 31% of those in the normal weight group were currently on a diet, while 21% of the underweight group was also on a diet. The distribution of bone density (%YAM value: Young Adult Mean) was as follows: 61 students (49%) were in the high density group (≥100); 58 students (47%) were in the middle density group (≥80-<100); and 5 students (4%) were in the low density group (<80). The more the bone density decreased, the greater the proportion of students with dieting experience. Among students with no dieting experience, the %YAM value was high when the BMI value was high. All of the students in the low density group had a desire to be thin, even though their bone density was low. Students who do not need to be thin had a desire to be thin and were considering continuing dieting going forward. Moreover, some students fell into the %YAM low density group, which is worrisome for the future.
