Women’s Health Initiative Observational Study

The Women's Health Initiative Observational Study (WHI-OS) is a large research project that tracks the health of thousands of women over many years. It observes their lifestyles, medical histories, and health outcomes without intervening, aiming to understand factors that influence conditions like heart disease, cancer, and osteoporosis. By identifying patterns and risk factors, the study helps guide health recommendations and preventive strategies for women's health. It’s an important tool for discovering how different behaviors and health choices impact long-term wellbeing in women.
