National Nutrition Survey

Japanese: 国民栄養調査 - こくみんえいようちょうさ

Based on the Nutrition Improvement Act (enacted in 1952), this is a national survey conducted once a year to clarify the health status and nutritional intake of the nation's citizens. Planned and designed by the Ministry of Health, Labor and Welfare, it is conducted on approximately 300 randomly selected districts (approximately 6,000 households, approximately 21,000 people). Physical condition surveys such as height, weight, and blood pressure are conducted by doctors and public health nurses in a group examination format, while dietitians visit each household to conduct interviews to determine food intake status. This provides information on the daily energy intake of each citizen, as well as the intake of each nutrient and salt. It also highlighted the increasing trend of skipping breakfast, and has contributed to improving the nation's eating habits by providing information for nutrition planning.

栄養改善法（1952年施行）に基づいて，国民の健康状態と栄養摂取の実態などを明らかにするために，年１回国が行っている調査。厚生省が企画立案し，無作為に抽出された約300地区（約6000世帯，約２万1000人）を対象として行う。身長・体重・血圧等の身体状況調査については，集団検診方式で医師や保健婦が行い，食物摂取状況調査については栄養士が戸別訪問をして聞き取りを行う。これにより国民１人１日当りのエネルギー摂取量や，各栄養素や塩分の摂取量などがわかる。また朝食抜きの傾向の増加なども浮き彫りにされ，栄養計画の資料として国民の食生活の向上に貢献してきた。
