女子大学生の給食経営管理実習における献立計画に及ぼす食品情報と食行動に関わる調査研究をした. 弁当群 (A群) 84人, 外食群 (B群) 66人を対比させ, 女子大学生における日常の昼食摂取状況の問題点を明らかにするとともに, 給食経営管理実習を通しての食教育の在り方を検討し, 次の結果を得た.<BR>1. 食材の再市場調査は全学生ではスーパーマーケットの利用が48%で最も高く, 食材の鑑別法は「賞味期限・品質保持期限」34%と「五感」31%が高く, 「JASなどの表示」の活用は15%で低かった.<BR>2. 食材の消費動向と生産・流通に関心のある者は45%, 30%で, 共に低く消費者教育の強化が望まれる.<BR>3.国産食品の利用はA・B群共に野菜類95%以上と顕著に高く, 輸入食品の利用ではA・B群共に果物, 肉・加工品が45%以上の高い割合であったが, A・B群間には差が認められた (p<0.05).<BR>4. 予定献立の食材料購入調査では再市場 (3箇所店舗) 価格か1回目に比べ約6%低額を示し, その上10種類の食品の重量を目測で推定した正解率も2~28%高くなり, 食材購入技術の修得に有効で期待された.<BR>5. 対象学生の身体状況ではBMIの平均は20.1±1.7, 平均体脂肪率は23.9±2.3%であったが, BMIは19.8以上~24.2未満の標準体型者には「かくれ肥満傾向者」を判定する体脂肪率24%以上~30%未満の者が56人 (37.3%) 存在していた.<BR>6. 日常の摂取エネルギー量は, 消費エネルギー量に対しての割合は平均74.6%で, 有意に低かった (p<0.05). 昼食の摂取エネルギーの割合は平均32.6%で, A・B群間に差がなかった.<BR>7. 昼食の取り方はA・B群ではそれぞれ経済的や簡便化を志向し習慣化していた.<BR>8. 1週間に1回以上の欠食者はA群が35.7%, B群が45.4%であった.<BR>9. 日常の昼食の栄養素摂取量は所要量の3/8量に対してエネルギー, カルシウム, 鉄, ビタミンC, 食物繊維が低く, 脂質が高く, 食事内容は「主食・飲み物」の組み合わせがA, B群共に上位で, 昼食行動に慎重さが欠けていた.<BR>10. 日常の昼食費は学内の給食費350円程度とほぼ同額で, この給食費と満足感との関連では満足者の割合が高かった.<BR>11. 給食の残菜量は料理の「分量」と「味: 美味しさ」に関連があることを認めた (p<0.01).

To investigate the influence of food information on the menu planning in schol lunch management practice, the problems regarding the daily lunches of women college students and the education method of eating, we have carried out an investigation involving 150 women students by dividing them into two groups (group A: eating a box lunch over 4 times a week, 84 students, 56%; group B: eating-out over 4 times a week, 66 students, 44%).<BR>1) The market re-purchase price of food materials (three individual stores) was about 6% lower and the hitting ratio in visually predicting the weights of 10 kinds of foods was 2-28% higher than the first time purchase, indicating the effective mastering of the points in purchasing materials.<BR>2) Food materials have been purchased from supermarkets in a frequency as high as 48%. The selection of food materials was 34% based on the expiration date or use-bydate, 31% on a sensory evaluation but only 15% on the JAS indications.<BR>3) Only 45% and 30% of the students, respectively, have shown interest in the consumption trend and production/distribution of foods. This shows a need for consumer education.<BR>4) Concerning the student subjects, their Body Mass Index (BMI) was 20.1±1.7, average somatic fat rate was 23.9±2.3%, and 37.3% of the students with a standard figure have a tendency of hidden obesity.<BR>5) The daily energy intake was 74.6% of the daily energy expenditure, being significantly low (p<0.05).<BR>6) A trend in taking lunch for both group A and B was economy and simplicity.<BR>7) 35.7% of the students in group A and 45.4% in group B did not take their lunch more than once a week.<BR>8) In their daily lunch, only three-eighths of the dietary allowance was satisfied and the intakes were all insufficient for energy, Ca, Fe, vitamins and dietary fiber but excessive for lipids. The combinations of staple foods and drink only were in ranked high suggesting a lack of consciousness about lunch. Nevertheless, the nutrient intake was improved in the school lunch menu.<BR>9) The lunch fee averaged 350 yen and was almost the same as the school lunch. A high percentage of the students was satisfied with the lunch fee and the school lunch.<BR>10) A relation was observed between the school lunch leftovers and the amount or taste of the menu (p<0.01).
