Outline of Final Research Achievements

This study was the first to examine among never-smoking women the association between secondhand smoke(SHS) and risks of ischemic heart disease(IHD), stroke, and total CVD in a large cohort in Asia. The study found that SHS from husbands may increase the risk of incident IHD in middle-aged nonsmoking women. In another large cohort, an association was found between SHS and risk of mortality from IHD among never-smoking women.
Examined the actual situation of secondhand smoke among female university students and the factors that promoted avoidance behavior toward secondhand smoke by a questionnaire survey. Having family members with secondhand smoke avoidance behaviors and unacceptable attitudes toward secondhand smoke were shown to facilitate secondhand smoke avoidance behaviors among female students.

Academic Significance and Societal Importance of the Research Achievements

大規模コホート研究において、受動喫煙と虚血性心疾患、脳卒中、全循環器疾患の発症リスクとの関連をアジアで初めて検討した。日本人の循環器疾患の発症タイプは欧米とは異なるが、本研究の結果によると、夫からの受動喫煙は、中高年の非喫煙女性の虚血性心疾患の発症リスクを高める可能性があり、この結果は欧米の結果を支持するものであった。
これまで明らかになっている受動喫煙回避行動の促進要因と併せて、家族に受動喫煙回避行動をとる者がいる場合について調査を行った。知識だけではなく、実際に回避行動をとっている家族等の身近な人の言動から学ぶ事が、受動喫煙の回避行動に繋がると分かった。
