    Since food frequency questionnaire (FFQ) can easily grasp the habitual dietary intake and is less burdensome for both participants and researchers, it is regarded as the best method in nutritional epidemiology. It is necessary to use a FFQ that is tailored to the target population and validated, but it is difficult to exhaustively search for the FFQ that could be used in your research. You need to confirm not only if the FFQ can estimate intakes of nutrients or food groups of interest, but also if the target group where the validity is examined is comparable to your participants. In this review, we used seven databases and systematically collected FFQs that were developed for Japanese and summarized the validity of target nutrients and food groups in order to help researchers who use or modify the existing FFQ. According to the 50 selected papers, more FFQs were examined their validity for women than men. As for age groups, the number of papers that examined the validity for those in their forties and fifties was the most. For target nutrients, many FFQs estimated the intake of energy and energy-generating nutrients such as protein, carbohydrate, and fat. For food groups, more FFQ were validated for the foods that can be easily showed and answered their portion size, such as fruit and milk.

    近年の日本における平均出生体重は減少傾向にあり,低出生体重児の出産割合もOECD諸国と比較して高い.出産年齢にあたる20~30歳代の女性は,やせの者の割合,喫煙率,主食・主菜・副菜を組み合わせた食事を摂ることがほとんどない者の割合が高く,牛乳・乳製品の摂取量が少ない.そこで,妊娠中の食行動及び夫婦の喫煙状況と体重増加との関連を調べた.

    2012年7月~2013年8月に都内の1病院にて健診を受けた,合併症のない単胎妊娠の妊婦を対象とした.妊娠15~20週時点で適切な体重増加量を指導し,妊娠中の健康的な食事についてのリーフレットを1回配布した.その後,健診毎に助産師が妊娠前のBMIに応じて設定された基準を使用して体重を評価し,簡単な食生活についての指導を行った.妊娠28週付近の体重増加が不十分または過剰であった76 名を本研究の対象とし,3日間の食事内容を記録するよう指示し,「主食・主菜・副菜の揃った食事を摂った回数(0~9)」,「牛乳・乳製品を含む食事を摂った日数(0~3)」を調べた.また,自記式アンケートと病院での問診で夫婦の喫煙状況を把握した.妊娠28週~出産までの体重増加量が不十分または過剰であった者を不適切(=0),適切であった者を適切(=1)としたダミー変数を従属変数にした階層的ロジスティック回帰分析によって,食事内容と喫煙の影響を調べた.

    喫煙については「適切」の群は夫婦とも全員が禁煙していたためオッズ比を算出することができなかったが,牛乳・乳製品の摂取日数が多いと妊娠中の体重増加が適切となった(オッズ比=2.20(95%信頼区間=1.10-4.37)).牛乳・乳製品は胎児の成長を促進するたんぱく質やIGF-1を含むほか,健康的な食事の要素とされている食品である.よって,牛乳・乳製品をよく摂取する者は食事に対する意識が高く,良い食習慣が身に付いていたと推察されることなどが適切な体重増加につながったと考えられる.

    The objective of this study was to examine factors associated with calcium (Ca) intake in female high school students. Survey participants consisted of female high school students and their mothers. Survey questionnaire items comprised participants’ personal attributes, dietary intake, and awareness of osteoporosis. Valid responses (33.6%) collected from 216 mother-daughter pairs were included in the analysis. The participants’ nutrient intake and dietary intake by food group were calculated. The students were then divided into two groups based on their Ca intake: a Ca-sufficient group and a Ca-deficient group. The students’ average Ca intake was lower than the estimated average requirement (550 mg/day). Nutrient density of Ca in the Ca-deficient group was significantly lower than in the Ca-sufficient group (p<0.01). Furthermore, multiple regression analysis (stepwise method) revealed that the students’ Ca intake was significantly associated with the intake of milk, beans, and nuts (p<0.01). Additionally, mothers of students in the Ca-sufficient group had a significantly higher intake of milk than mothers of students in the Ca-deficient group, which was significantly associated with milk intake (p<0.01). As regards osteoporosis awareness, a significant in ter-generational difference was observed between mothers and daughters (p<0.01), but there was no difference between the students’ Ca-sufficient and Ca-deficient groups (p<0.05).

    Based on the aforementioned findings, it can be said that in order to increase female high school students’ Ca intake, it is necessary to educate them on the importance of maintaining bone health throughout life. Moreover, to attain and maintain behavioral changes in students, it may be necessary to examine approaches that take the actual circumstances of the students into account.
