The subcutaneous fat thickness was investigated to obtain the general characteristics of Japanese fat distribution by sex and age. Our subjects consist of 1, 477 males and 1, 933 females of all age groups in various localities in Japan. The newly developed A-mode type ultrasonic instrument was utilized to measure fat thickness including such locations as biceps, triceps, subscapula, suprailiac, thigh anterior, thigh posterior, and calf. The data obtained were analyzed by mean, standard deviation, and percentile. Our findings are summarized as follows: 1) It is confirmed that the subcutaneous fat layer of females is thicker than that of males. 2) Examining the ratio of upper-arm and trunk in subcutaneous fat layer, i.e. (biceps+triceps)/(subscapula + suprailiac), the adults' ratios are smaller than those of infants, and adult males accumulate more fat abdominally than adult females do. 3) The percentiles we obtained will provide the criteria for subcutaneous fat thickness of the Japanese by sex and age.

A-mode式超音波皮脂厚計(TATT TH-500)を用いて,日本人の皮下脂肪厚の性・年齢別度数分布を作成するために,今回は小学生(1~6年生)の皮脂厚の計測を行なった.1986年5月から7月にかけて東京都にある4つの某小学校の児童1925人(男子:984人,女子941人)を対象にして,4部位の皮脂厚を計測した.主な結果は以下の通りである. (1)小学生の全学年(7~12歳)において,いずれの部位でも女子の皮脂厚の方が男子よりも厚い傾向が認められた. (2)小学生における4部位(biceps,triceps,subscapular,suplailiac)の皮脂厚は,年齢に伴い概ね漸増する傾向が示唆された. (3)超音波皮脂厚計を用いて,4部位における小学生の皮脂厚の度数分布を作成した. (4)部位別皮下脂肪厚と身長,体重,Kaup指数との関連を,年齢の影響を除去して男女別にそれぞれ全例について検討したところ,以下に示す結果が得られた. 1)身長と各部位別皮下脂肪厚及びこれらの合計値との間には男女ともに正の相関(0.2~0.3)が認められた. 2)男女ともに,体重が重いほど各部位別皮脂厚値及びこれらの合計が大きいという関係が認められた. 3)Kaup指数が体重,比体重,Rohrer指数よりも皮脂厚値と最も強い正の相関が認められた.

(1) To apply the ultrasound technique to measuring the subcutaneous fat thickness in neonates. (2) To test the hypothesis that there is a relationship between the neonatal weight loss and their changes of subcutaneous fat thickness during the same period. (3) To relate the results to the maternal and neonatal data. The thickness of subcutaneous fat layer were measured in 172 infants within 24 hours of birth, on the second and the fourth day from the birth, using then pulsed ultrasound apparatus. Six sites were chosen over the right side of the body; (1) biceps (2) triceps (3) subscapular (4) suprailiac (5) upper breast (6) front thigh. The birthweight, gestational age, some anthropometric data at birth, and maternal characters were also recorded. The ultrasonic pulses were clear enough to read when measuring the subcutaneous fat thickness in the neonates. The mean of the fat thickness on the third day was significantly smaller than that of the day of birth, i.e. the first day and the fifth day, indicating the relationship with the weight loss during the four days after birth . It was obvious that fat thickenss is related with birthweight and not with gestational age. The effects of other elements on the fat thickness are now under analysis.

Not few investigators have story interest on the relation between food intake and mortality. From the viewpoint of Dr. Kondo, we have also been motivated to survey Yonaguni Island of the Ryukyu Islands.<br>Dr. Kondo suggested that food consumption in this island would be characteristic and biased to the large intake of fish and meat.<br>But nobody can exactly describe the status of food in Yonaguni Island because no dietary survey on its inhabitants has been conducted.<br>We had a happy chance to do make a dietary survey there in October 1973, in jointwork of the Yaeyama Health Center.<br>Subjects; The subjects of this survey were fifty eight families selected at random from three hamlets (Sonai, Kubra and Hikawa)<br>Results; The results are shown below.<br>1. The intake of calories, protein, fat and vitamin C was estimated to be higher than the average of the Japanese National Nutrition Survey of 1971.<br>On the other hand calcium and vitamin B<sub>2</sub> was estimated as fairly lower than national levels.<br>2. In comparison with those surveys, the amount of several food items; fish, meat, green and yellow vegetables in Yonaguni are estimated to be higher than the National Level and Okinawa Island.<br>3. Food intake patterns differ among the three hamlets, which compose the community of an isolated island.<br>4. On the other hand, there is little difference in food preparation among them.<br>5. From above it may be said that the dietary intake of the hamlets is in unity, whereas food preparation is definite as the whole island.
体脂肪量を超音波皮脂厚計によって、被計測者に侵襲を与えることなく、推定する方法の確立を図っている。その推定値の誤差を規定するために、【^(40)K】計測法(ヒューマン・カウンタ法)とNMR診断法の人体断面像から脂肪量を推定する方法を基準として、超音波皮脂厚計法の推定誤差が約5%以内であることを明らかにした。NMR画像はまだイメージスキャナーで面積計算ができないので、目下、PC98型コンピュータで処理するソフト・ウェアの開発中である。したがって、【^(40)K】計測値だけを較正値として超音波皮脂厚法の誤差を算定した。その算定に用いた資料は、【^(40)K】法の68名(男34名,女34名)、超音波皮脂厚法の68名(【^(40)K】と同じ対象)の7ケ処の計測値である。なお、NMR画像は7名分の資料が得られている。体脂肪量;F(kg)=【α_1】・【X_1】+【α_2】・【X_2】+【α_3】・【X_3】+……+βただし、【α_1】,【α_2】,【α_3】・・・:性・・年齢別に推定される定数β:【α_1】・【α_2】・・に同じ【X_1】,【X_2】・【X_3】・・・:各部位C1,2,3,・・・)の皮脂厚値である。これに、性・年齢別に実測値を用い、(1)【^(40)K】計測値に近似させる、(2)変量(X)の数をなるべく少くすることを条件として検討した結果男性:F(kg)=0.556(上腕部皮脂厚)+0.094(腹部皮脂厚)-7.961(推定誤差:4.4%)であることがわかった。女性(30歳以下,30歳より上にわけた)についても2変量で約5%の推定誤差で推定できることがわかった。今後は、例数をふやし、性・年齢別の体型の変化にも注意を払った推定式を目標に改善を続けたい。
