Question 1

What is the Meaning of WHI Trial?

Accepted Answer

The WHI Trial, or Women's Health Initiative Trial, refers to a series of large-scale, long-term national health studies initiated in the United States, primarily investigating major causes of death, disability, and poor quality of life in postmenopausal women.

Question 2

What is the Context of WHI Trial?

Accepted Answer

This extensive research program focused on prevalent health concerns affecting women beyond menopause, including cardiovascular disease, various cancers, and osteoporosis, with a substantial randomized controlled trial component specifically examining the effects of hormone therapy regimens.

Question 3

What is the Significance of WHI Trial?

Accepted Answer

The findings from the WHI trial significantly altered the clinical understanding and global application of postmenopausal hormone therapy, prompting a critical re-evaluation of its risk-benefit profile and leading to revised clinical guidelines for its prescription and use.

Question 4

What is the Mechanism of WHI Trial?

Accepted Answer

The core of the WHI involved randomized, placebo-controlled clinical trials where healthy postmenopausal women received either active hormone therapy, specifically combined estrogen and progestin or estrogen alone, or an inert placebo. Participants were then meticulously followed to monitor the incidence of predefined health outcomes over time.

Question 5

What is the Application of WHI Trial?

Accepted Answer

In clinical practice, the evidence generated by the WHI is fundamental for guiding discussions with postmenopausal individuals regarding menopausal symptom management and long-term health strategies. It helps clinicians and patients make informed decisions about the appropriateness, type, and duration of hormone therapy based on individual health profiles and risks.

Question 6

What is the Metric of WHI Trial?

Accepted Answer

Key health outcomes measured and analyzed in the WHI included the incidence rates of coronary heart disease, stroke, venous thromboembolism, breast cancer, colorectal cancer, hip fracture, and all-cause mortality. These events were rigorously tracked and statistically compared between the intervention and placebo groups to ascertain the effects of hormone therapy.

Question 7

What is the Risk of WHI Trial?

Accepted Answer

The trial definitively identified increased risks of stroke, blood clots (venous thromboembolism), and breast cancer associated with combined estrogen and progestin therapy, and an elevated risk of stroke with estrogen-alone therapy, particularly in older postmenopausal women. These findings underscore the necessity of careful patient selection and a thorough assessment of individual risks before initiating hormone therapy.
