Frequency-risk and duration-risk relations between second-hand smoke exposure and menopausal symptoms among middle-aged women in Guangzhou, China

摘要

Objective Tobacco smoking and menopausal symptoms are strongly associated, but the possible effects of second-hand smoke (SHS) have not been evaluated. This study aimed to explore the possible frequency-risk and duration-risk relations between SHS exposure and menopausal symptoms among non-smoking, middle-aged women.
