Purpose:

The purpose of this study is to examine the effects of essential fatty acid (EFA) supplementation on bone metabolism and frailty in postmenopausal women. The overall hypothesis is that EFA supplementation, via its immunoregulatory and anti-inflammatory activity, will decrease bone turnover, decrease prostaglandins and cytokines associated with bone metabolism and frailty, and change physical outcome measures associated with frailty in postmenopausal women with low bone mass and frailty.


Study summary:

Osteoporosis is a bone thinning disease that results in fractures that occur with minimal trauma. The direct health care costs related to osteoporosis are estimated to be $14 billion per year, comparable to costs in heart failure and asthma. Frailty, or poor physiologic reserve to deal with stressors, is estimated to be 7% in the general population over age 65. The frailty syndrome is characterized by sarcopenia or muscle loss, inflammation, low estrogen, growth hormone and testosterone levels, poor nutrition and disability, and is associated with an increased risk of falls and fracture. Omega-3 fatty acids found in fish oil (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) have been shown to decrease markers of inflammation (cytokines) and decrease death due to heart disease. A number of studies in animals suggest that fish oil (EPA and DHA) supplementation inhibits bone break down, increases calcium absorbed from the diet and enhances calcium in bone. Few studies have assessed the role of n-6 and n-3 fatty acids in the diet in bone disease in humans. As far as we know, no study has evaluated the role of n-3 fatty acids in the frailty syndrome.
