Keywords栄養教育 / タンザニア / 妊産婦 / 教材開発
Outline of Research at the Start

タンザニアでは妊産婦に栄養失調対策が急務であるが、栄養教育の重要性が十分に認識されず利用できる教材が極めて限られている。本研究では、タンザニアにおける妊産婦への栄養教育プログラム開発に向けて、妊産婦らや助産師らが取り入れやすいスマートフォンアプリ教材の開発と評価を目指す。はじめに妊産婦らを対象に健診成績、栄養状態、食慣習・栄養知識レベルなどに関する調査を行う。次に助産師らを対象に栄養教育の実践状況とニーズの調査を行い、現地の食文化や栄養状態に即したアプリ教材を開発する。さらにアプリ教材の使用感についてフィードバックを得ながら、妊産婦らが理解しやすく、医療従事者も取り入れやすい教材へと改良する。

Outline of Annual Research Achievements

タンザニアでは、妊産婦・乳幼児共に栄養失調対策が急務であるが、栄養教育の重要性が十分に認識されず、栄養教育に利用できる教材が極めて限られている。本研究課題では、タンザニアにおける妊産婦への栄養教育プログラム開発に向けて、効率的・効果的かつ妊産婦らや助産師らが取り入れやすいスマートフォンアプリ教材の開発と評価を目的とした。
2024年度は、前年度に対象者の妊婦健診で収集したデータを整備し、データベースを構築し、アプリ開発向けの情報としてデータ解析を行った。また、タンザニアにおける世帯の経済的不平等が母子における栄養不良の二重負荷にどのような影響を与えるかを、ビッグデータを用いて分析し、論文を発表した。研究の結果から、家庭経済が良好であるほど栄養不良の二重負荷のリスクが高まる一方で、食事の多様性が高い場合にはそのリスクが軽減されることが示唆された。この知見は、社会経済環境から生じる課題に対して、地域や個人レベルでの介入の可能性を提示するものであり、同様の社会経済的課題にも適用が期待される。従来は、過栄養と低栄養にそれぞれ独立した対策が行われてきたが、食事の多様性に着目した栄養介入はこれらの有力な解決策となり得よう。得られた知見をもとに、開発アプリ教材のパイロット版の開発においては、現地で入手可能な食材の選択や、食生活の多様化を推進する視点から行った。タンザニア人の公衆栄養学専門家などと連携し、妊産婦向け栄養教育コンテンツ(映像・印刷教材等)の企画・作成・編集を行った。企業と協力して、視覚教材や音声を導入できるアプリのパイロット版を作成した。現地文化と食習慣に配慮した表現およびスワヒリ語でのナレーション・字幕を含むビデオとリーフレットを導入した。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

当初予定していた妊産婦における栄養教育コンテンツ開発(パイロット版)は、タンザニア国立食品栄養センター(TFNC)の公衆栄養学専門家と連携しながら、一年間をかけて順調にほぼ完了した。

Strategy for Future Research Activity

2025年度は、タンザニアの妊産婦を対象とした食生活および健康に関する解析結果を取りまとめ、学術論文として発表することを目指す。また、妊産婦および医療従事者をそれぞれ対象とし、パイロット版のアプリ教材を評価し、栄養教育の実装を妨げる要因および促進する要因に関するアンケート調査およびインタビューを実施する予定である。得られた知見をもとに、栄養教育コンテンツの改良を図るべく、タンザニアの公衆栄養学専門家および母子保健分野で活動する助産師を含む現地共同研究者らと協議・検討を行い、実用性と文化適合性を兼ね備えた教材の改良に取り組む予定である。
