Early Menopause and Hormone Therapy may Impact Lung Health: Insights from PLCO Trial Analysis

For this purpose, the research team estimated the risk among 69,706 postmenopausal women in the PLCO trial, stratified by menopausal types and smoking status.

The study revealed the following findings:

• Early M was associated with an increased risk of most lung disease and mortality outcomes in ever smokers with the highest risk seen for respiratory mortality (HR 1.98) in those with bilateral oophorectomy (BO).
• Early-M was positively associated with chronic bronchitis, and all-cause, non-cancer, and respiratory mortality in non-smokers with natural menopause or BO, with the highest risk seen for BO— respiratory mortality (HR 1.91).
• Ever MHT was associated with reduced all-cause, non-cancer, and cardiovascular mortality across menopause types irrespective of smoking status and was additionally associated with reduced risk of lung cancer, non-ovarian cancer, and respiratory mortality in ever smokers.
• Among smokers, ever MHT use was associated with a reduction in HR for all-cause, non-cancer, and cardiovascular mortality in a duration-dependent manner.

As the scientific community continues to unravel the complex interplay between menopause, hormone therapy, and overall health, insights from studies like this underscore the importance of personalized healthcare approaches tailored to women's unique hormonal profiles and medical histories. This research opens avenues for future investigations into optimizing respiratory health strategies for women transitioning through menopause.
