The purpose of this study was to get a data which can provide a basis for future direction in nutritional education and to build up right eating habit and to find the way how to improve food life and the nutritional supply by evaluating the current nutritional intake of average middle school girls through the survey study of their daily food intakes and physical status.
The survey of nutritional intakes and physical status in two girls middle schools, namely Jang’hung girls middle school at Jang’hung Up and Bo’song girls middle school at Bo’song Up, were carried by teachers majoring in Home Economics and nurse-teachers from 5 July to 7 July 1983. From a total of 1080 subjects of two girls middle schools, 887 subjects were surveyed.
The results obtained from survey are summarized as follow:
1) Physical Status
Average height, weight and chest girth of subjects in both middle schools were much lower than the Korean average standard (p＜0.005~p＜0.001) and t-score of differences between two middle school girls were not significant.
R?hrer index, nutrition rate and physique rate were also lower than Korean averag standard through all the ages in both girls middle schools.
Menarche appeared mainly between the age of 13 to 15 (91.55 %), with a mean age of 14 (35.01 %) and which was experienced by the subjects of 51.52 percentage among total surveyed middle school girls.
2) Nutritional Intakes
The average daily intakes of all nutrient except iron, vitamin A, thiamin, ascorbic acid and niacin was lower than Korean Recommanded Dietary Allowances (RDA). Especially average intake of calorie and calcium were much lower than Korean RDA(p＜0.001) while average intake of thiamine and ascorbic acid were much higher than Korean RDA (p＜0.001).
T-score of differences of iron, thiamin, riboflavin between two middle school girls were very significant (p＜0.001).
Generally iron and riboflavin were the highest rate of intakes through three meals and breakfast took charge of considerable amount of all nutrient intake without omitting anything (about 30 % of daily nutrient intake).
The nutrients of which ratio of nutrient intake by snack was more than 16.7 % were vitamin A, thiamin, riboflavin, ascorbic acid etc. and snack foods which were intaked frequently in both middle school girls commonly were fruits, milk and milk products, bread and biscuits in sequence.
3) Correlations and t-score between physical status, menarche and nutrient intakes.
Average intake of calorie at Jang’hung area was positively correlated with height, weight, nutrition rate and physique rate and this correlation was very significant (p＜0.005). Average intake of calorie was also correlated with chest girth and R?hrer index (p＜0.05).
At Bo’song area, averae intake of riboflavin was negatively correlated with all the items of physical status (p＜0.05-p＜0.005), vitamin A was negatively correlated with chestg irth and R?hrer index (p＜0.05 respect ively) and thiamin was also negatively correlated with chest girth, R?hrer index and nutrition rate (p＜0.05 respectively). Especially niacin showed a negative correlation with all the items of physical status very significantly (p＜0.005).
The time of menarche showed a positive correlation with iron in both middle school girls commonly p＜0.05 at Jang’hung, p＜0.10 at Bo’song).
