Outline of Research at the Start

途上国、特にアフリカの低開発地域においては、持続可能な開発目標(SDGs)の子供たちの健康目標に関する科学的根拠は殆ど存在しない。研究代表者らがこれまでにアフリカでの研究展開において開発した研究ツールやこれまでの研究成果を連動させ、妊娠から出生、その後の子供の発育に関しての出生コホートを構築し、環境と子供の成長に関する疫学研究を展開する。

Outline of Final Research Achievements

This study established a birth cohort in Kwale County, Kenya, to identify factors associated with stunting in early childhood. A total of 806 mother and child pairs were enrolled and followed longitudinally, with a nested case-control design implemented. The stunting rate was 25.9%, and comprehensive data on aflatoxin levels, dietary practices, and socioeconomic conditions were collected. The study also found a significant association between newly defined hypertension criteria and preterm birth. Despite COVID19 related challenges, a local implementation system was successfully established, enabling the collection of high-quality epidemiological data.

Academic Significance and Societal Importance of the Research Achievements

本研究は、発育阻害の高リスク地域において出生コホートを構築し、栄養、感染、環境要因など多因子の影響を縦断的に分析した点で学術的意義が高い。特にアフラトキシンや妊婦高血圧との関連は新たな知見を提供した。社会的には、途上国における母子保健の改善や公衆衛生政策の科学的基盤となるエビデンスを提供し、SDGsの目標達成に資すると考えられる。
