Abstract :1.1965年12月と1966年5月の2回にわたって, 那覇教育区立城北小学校の学童, 9歳から11歳までの男子200名, 女子183名について, 栄養状態を調べ, 栄養素別摂取状況, 食品群摂取状況, 栄養比率, 食品群別熱量および栄養素比率, 蛋白価, そして身体計測および身体症候発現率について結果をまとめた。2.栄養素別摂取状況は, 各年齢別の摂取量に大差はないが, 所要量に対する摂取率は, 熱量62∿74%, 蛋白質55∿75%, 脂質69∿94%, カルシウム37∿76%, 鉄71∿82%, ビタミンA30∿48%, ビタミンB_193∿120%, ビタミンB_2 91∿131%, ビタミンC56∿111%となり, B_1,B_2を除いて他の栄養素の不足が目立つ。特に不足しているのは, 5月のカルシウム(当日ミルク給食がなかった。), そして, いづれの季節ともビタミンA, 蛋白質となっている。ついで5月のビタミンCの不足が目立つ。3.食品群別摂取状況で, 各年齢別の総摂取量は女子が9,10,11歳の順に増加している。男子では必ずしも年齢増に従って摂取量の増加はみられない。摂取めやすに対する食品群別摂取量の比率は, 穀類80∿95%, 芋類10∿16%, 砂糖6∿8%, 油脂類25∿42%, 乳類3∿33%, 卵46∿71%, 魚肉獣肉類53∿80%, 豆類33∿57%, 緑黄色野菜類19∿28%, その他の野菜類29∿47%, 果実類34∿60%, 食品総摂取量37∿51%で, どの食品群とも著しく低い。4.栄養比率については良好な傾向がみられ, 総蛋白質に対する動物性蛋白質の比が39∿46%, 総カロリーに対する蛋白質カロリー比が13∿15%, 脂質カロリー比が17∿20%, 糖質カロリー比が66∿69%, 穀類から得られるカロリー比が59∿72%である。食品群別熱量および栄養素比率で, 比率の高いものをあげると, 熱量は穀類, 蛋白質も穀類, 脂質は油脂類, カルシウムは乳類, 鉄は穀類, ビタミンAは緑黄色野菜類, ビタミンB_1,B_2とも穀類, ビタミンCはその他の野菜類となる。すなわち, これらの食品が各栄養素の主な給源となっている。5.蛋白価は12月の食餌調査のものは平均77で, 5月には平均75となり, 第一制限アミノ酸は含硫アミノ酸である。6.身体計測の結果から, 身長および体重は全琉の学童の平均値と比較して, 男子では身長がややすぐれ, 体重でやや劣り, 女子では身長は劣っているが, 体重においてすぐれている。身体症候発現状況をみると, 有症者男子27%, 女子31%で女子にやや多い。男女とも腱反射消失, 毛孔性角化症, 貧血の発現率が高く, 口角炎は男子にのみ3.0%みられる。季節別にみると有症者は12月に28%, 5月に29%で大差ない。貧血, 毛孔性角化症, 腓腹筋圧痛, 浮腫は12月に多く, 口角炎, 腱反射消失は5月に多発している。
1. Two nutritional surveys were conducted by the joint work of two research groups, one medically-oriented and one dietary-oriented. The surveys were conducted on two different dates at interval of approximately 5 months : the first survey in December, 1965 and the second survey in May, 1966. The subjects were 383 pupils of the Johoku Elementary School, 200 boys and 183 girls, ranging in age from 9 to 11 years. The results were analyzed on the following aspects : actual intakes and the percentages of intake, classified by nutrients and food groups; protein scores; and physical measurements and appearance of physical symptoms. 2. In the dietary survey, there was little difference in nutritional intake between boys and girls. However, the percentages of intake were low on every nutrient except vitamin B_1 and vitamin B_2 when compared with the nutritional requirements, summarized as follows; Calories ranged in the two surveys from 6%∿74%, protein 55%∿75%, fat 69%∿94%, calcium 37∿76%, iron 71%∿82%, vitamin A 30%∿48%, vitamin B_1 93%∿120%, vitamin B_2 91%∿131%, vitamin C 56%∿111%. 3. The low percentage of calcium intake in May, 1966 was noted because the pupils did not receive milk on the day the survey was taken. Nutritional deficiencies are especially noticeable in the intake of vitamin A, protein, and in the summer time, vitamin C. Food intake, classified by age, shows that the total intake of girls increased at they got older, but the same results were not found among boys. The percentages of actual food intake of the pupils as compared with the recommended food intake are as follows; cereals 80%∿95%, potatoes 10%∿16%, sugars 6%∿8%, fats and oils 25%∿42%, milk and milk products 3%∿33%, eggs 46%∿71%, fish and meat 53%∿80%, pulses 33%∿57%, green and yellow vegetables 19%∿28%, other vegetables 29%∿47%, fruits 34%∿60%, and total intake 37%∿51%. The above results indicate extremely low intakes of foods in each food group. 4. Approximately 39%∿46% of total protein is taken from animal sources and 13%∿15% of total Calories were obtained from protein. The Calories from fats are approximately 17%∿20%, and the Calories from carbohydrates are 66%∿69% of the total Calories. This proportion indicates a relatevely good intake pattern. The main sources of each nutrient from food groups are as follows : Calories, protein, iron, vitamin B_1 and vitamin B_2 are from cereals; fat is from fats and oils; calcium is from milk; vitamin A is from green and yellow vegetables; and vitamin C from other vegetables. 5. The average protein score of December, 1965 is 77 and that of May 1966 is 75. The first limiting amino acid for the both seasons is sulfur-containing amino acid. 6. In regard to physical condition, approximately 27% of the boys and 31% of the girls show various symptoms of nutritional deficiency. Loss of knee-jerk reflex, follicular keratosis and anemia are found to be high in percentage regardless of sex and angular stomatitis is found only among boys (3%). The seasonal effect on the percentages of positive findings is not noticeable. However, anemia, follicular keratosis, calf tenderness and edema are relatively high in December, while angular stomatitis and loss of knee-jerk reflex are high in May, 1966.
