Measurement of systolic blood pressure (SBP), fatty mass (%Fat) and food intake were carried out on 252 females aged 20-72 years living in mountainous, rural and suburban districts. Measurement of SBP was made on the right arm with subjects in a seated position by automatic sphygmomanometer (BP-103, Nihon-korin Co.) and Riva-rocci sphygmomanometer. %Fat was estimated from skinfold according to the method of Nagamine. Observation of food intake was conducted by a routine questioning, however, checks and counter checks were made by personal interviews until reliable figures had satisfactorily been obtained. And the unit of daily intake of thiamin and riboflavin was expressed as the values per kilocalorie of caloric intake and that of caloric intake and other nutrients was expressed as the values per kilogram of body weight. No significant correlation was found between SBP and %Fat, but only 17 persent of subjects whose SBP above 140 mmHg showed higher %Fat than 30.0% in the case of mountainous village, however, the appearance rate was 56 percent in the case of suburban districts. Significant negative correlatians were found between SBP and calorie, protein, animal protein, fat, animal fat, iron and sodium at 1% level and calcium, retinol potency and thiamin at 5% level. Significant positive correlation was found between SBP and age at 1% level. Significant partial correiations were found between SBP and calorie, protein, animal protein and animal fat at 1% level and fat and retinol potency at 5% level when the elimination of the effect of age was made. And after the elimination of the effects of caloric intake, significant partial correlation was found only between SBP and animal protein (P＜0.05), and significant partial correlations were found between SBP and calorie at 1% level and protein at 5% level when the elimination of the effect of animal protein Intake was made. However, significant positive correlations were found between most of nutrients intake and intake of calorie and animal protein. These results imply that different factors have to be considered according as the difference of living style for the the prevention of essential hypertension, and in the case of this investigation, it may be said that obesity or physical inactivity, low animal protein intake or malnutrition are factors of high SBP, however, SBP was not affected by sodium intake.農村,山村および都市に居住する成人女子(20〜72才)252名を対象に,収納期血圧(SBP)と身体組成(%Fat),食餌との関係について検討討を加えた。1.SBPと%Fatとの間には有意な相関々係は認められなかったが,SBPが140mmHg以上の人のうち%Fatが30%以上の人の出現率は,都市では約59%,山村では約17%であり,その出現率の差は統計的に有意であった。2.SBPと年令,エネルギー,蛋白質,動物性蛋白質,脂質,動物性脂質,鉄,カルシウム,ナトリウム,ビタミンAおよびビタミンB1の摂取量との間にはそれぞれ有意な相関々係が認められた。しかし,年令の影響を除外した場合にSBPと有意な負の偏相関々係が認められたのは,エネルギー,蛋白質,動物性蛋白質,脂質,動物性脂質およびビタミンAだけであった。3.摂取エネルギーの影響を除外した場合には,SBPと動物性蛋白質摂取量との間のみ有意な負の偏相関々係が認められ,動物性蛋白質摂取量の影響を除外した場合には,SBPとエネルギーおよび蛋白質の摂取量との間にのみ有意な負の偏相関々係が認められた。4.摂取エネルギーと動物性蛋白質摂取量とその他のほとんどの栄養素の摂取量との間には,それぞれ有意な正の相関々係が認められた。5.以上の結果から,生活形態が異なれば,SBPに影響を及ぼす要因やその要因の持つ意味が異なるものと考えられた。そして,本研究の被験者のような集団では,肥満または運動不足,動物性蛋白質摂取量の不足またはアンバランスな栄養素の摂取はSBPに悪影響を及ぼしていると考えられたが,動物性脂質およびナトリウムの摂取量がSBPに影響を及ばしているとは考えられなかった
