Background

The adolescent years are a window of opportunity to influence lifelong bone health. Bone acquisition is accelerated within the genetic potential by lifestyle choices. But some adolescent girls do not care about healthy lifestyle and nutrient uptake. Therefore, we investigated the nutrition and health behavior relating to bone acquisition.

Methods
A cross-sectional study was administered to high school girl students from 4 general and 4 commercial high schools in Uijongbu, Incheon, Suwon, and Yongin. The data was gathered from 378 girls by self-reported questionnaire, which included age, height, weight, health behavior relating to bone acquisition and food-frequency. Nutrient uptake was assessed by DIET PLUS 3.0 program.

Results
Girls with bone acquisition inhibiting health habits were reported. Among subjects, 12.2% had regular alcohol intake, 21% smoked daily, 77.7% did not exercise regularly, 58% had light-activity, 42.2% experienced weight reduction trial, 30% had low body weight and 72.8% had less than 2 meals a day. In nutrient uptake, 33.1% of subjects took less calcium uptake and 4% less protein uptake than recommended daily allowance. Comparing general and commercial high schools, commercial students had more bone acquisition inhibiting health habits.

Conclusion
There were many high school girl students with bone acquisition inhibiting health and eating habits. Family physicians need to promote and educate good health habits with a balanced meal associated with bone acquisition in girls, especially commercial high school students.
