Abstract

Background: During the year after the Great East Japan Earthquake on March 11, 2011, the health conditions and lifestyles of survivors were extensively surveyed. We examined the relationship between living conditions and dietary pattern among survivors.

Methods: A total of 10 466 survivors aged 18 years or older (25% of the population of that age in the area) participated in a survey of Iwate Prefecture. The average frequency of daily consumption of 8 food groups was determined by questionnaire. After excluding staple foods, which were consumed 3 times a day by 85% of participants, factor analysis was performed on 7 food groups among 9789 people (3795 men, 5994 women).

Results: Factor analysis identified 2 dietary patterns-prudent and meat. The prudent dietary pattern is characterized by high intakes of fish and shellfish, soybean products, vegetables, fruit, and dairy products and was more evident among older participants and women. The meat dietary pattern is characterized by high intakes of meat and eggs and was more evident among younger participants and men. Age-adjusted multiple logistic regression analyses showed that male and female current smokers and men and women living in difficult conditions were likely to have a lower prudent dietary pattern score; male current smokers and male daily alcohol drinkers were likely to have a higher meat dietary pattern score.

Conclusions: During the year after the earthquake, the prudent dietary pattern was associated with better living conditions among survivors, whereas the meat dietary pattern was not.

背景:: 2011年3月11日の東日本大震災からの1年間に、被災者の健康状態や生活習慣が広範囲に調査された。本研究は被災者の暮らし向きと食事パターンの関連を明らかにすることを目的とした。

方法:: 岩手県の調査地域において、同年齢の人口の25%に相当する18歳以上の10,466人が参加した。質問票により、8食品群について毎日の平均摂取頻度の回答を得た。対象者の85%が3回摂取していた主食を除き、7食品群について9,789人(男性3,795人、女性5,994人)を対象に因子分析を行った。

結果:: 因子分析により、健康志向と肉食志向の2つの食事パターンが同定された。魚・貝等、豆腐・納豆等、野菜、くだもの、牛乳・ヨーグルト・チーズ等の高摂取頻度で特徴付けられる健康志向パターンは、高齢の者及び女性において顕著であった。肉と卵の高摂取頻度で特徴付けられる肉食志向パターンは、若年の者及び男性において顕著であった。年齢調整した多変量ロジスティック回帰分析の結果、男女とも現在喫煙者と暮らし向きが苦しい者において健康志向パターンの得点が低い者が多く、男性では現在喫煙者と毎日飲酒者において肉食志向パターンの得点が高い者が多かった。

結論:: 大震災後1年間の被災者では、健康志向パターンは暮らし向きと関連していたが、肉食志向パターンではその関連はみられなかった。
