Mortality in Younger Postmenopausal Woman Reduced by HRT

A new study says that hormone replacement therapy (HRT) decreases mortality in younger postmenopausal women.

For more than 60 years, HRT has been widely used to treat menopausal estrogen deficiency and may studies had reported that it was linked with a significant reduction in total mortality among younger postmenopausal women.

Hormone Replacement Therapy
Hormone Replacement Therapy can be likened to an ‘oasis in the desert’ for women in the throes of menopause.

The available evidence also supported the routine use of HRT to increase longevity in postmenopausal women.

However, the 2002 publication of a major study, the Women's Health Initiative (WHI), indicated increased risk for certain outcomes in older women, without increasing mortality, which led to a debate regarding potential benefits or harm of HRT.

In an article researchers conducted a meta-analysis of the available data using Bayesian methods and concluded that HRT almost certainly decreases mortality in younger postmenopausal women.

Human Growth Hormone (HGH) - Preview
Human growth hormone, otherwise known as somatotropin, stimulates growth, cell reproduction, and bone regeneration.

Bayesian analysis uses prior data, updated with new information, to make statistical inferences.

The authors pooled results from 19 randomized trials that included age-specific data from the WHI, with 16,000 younger postmenopausal women (mean age 55 years) followed for 83,000 patient-years, and showed a mortality relative risk of 0.73.

Acne vulgaris, popularly known as ‘pimples’ or ‘zits’ is a skin condition affecting most teenagers.

After adding data from 8 observational studies, the resultant relative risk was 0.72.

Using Bayesian analysis to synthesize the available data, the probability of a mortality benefit in this population was 1.0, which means that the probability of the hypothesis that hormone therapy reduces total mortality in younger women is essentially 1.

What is Menopause?
Menopause is defined as the state of permanent cessation of menstrual cycles (periods) for 12-months.

"It is clear that these findings need to be interpreted in the light of potential benefits and harms of hormone therapy. The available evidence indicates that hormone therapy in younger postmenopausal women increases the risk of breast cancer and pulmonary embolism and reduces the risk of cardiovascular events, colon cancer, and hip fracture," said Dr. Shelley R. Salpeter.

"The cardiovascular benefit is a result of a small absolute increase in stroke and a greater reduction in coronary heart disease events. The total mortality benefit for younger women seen in the randomized trials and observational studies indicates that the reduction in deaths from coronary heart disease, fracture, and colon cancer outweighed the increase in deaths from breast cancer, stroke and pulmonary embolism.

"In addition to this mortality benefit, hormone therapy in younger women provides an improvement in quality-of-life measures, at least in the first few years of treatment," she added.

The study has been published in the latest issue of The American Journal of Medicine.
