Osteoporosis is a common condition which leads to significant morbidity and mortality from fractures. Several treatments for osteoporosis are licensed in the UK, including oral medications and injectable treatments. Some treatments work by preventing bone loss (antiresorptive treatments, such as intravenous zoledronate or subcutaneous denosumab) and others by increasing new bone formation (anabolic treatments, such as subcutaneous teriparatide).

Obesity is also very common in the general population and leads to a number of adverse health outcomes. There is increasing research interest in the relationship between bone and fat in both humans and animal models. Bone specific hormones such as osteocalcin have been shown to alter insulin sensitivity and fat deposition in animals, and other studies have suggested that these relationships also exist in man. Specifically, reduced levels of osteocalcin (seen when bone turnover is reduced) have been associated with increased fat mass and insulin resistance, suggesting an adverse effect on fat metabolism.

This study aims to investigate whether 3 different injectable treatments currently being used for osteoporosis (zoledronate, denosumab and teriparatide) have an effect on fat metabolism in patients. To achieve this we aim to recruit patients routinely commencing these treatments as part of usual clinical care, and assess changes in their metabolism before and after treatment. The assessments will include basic measurements such as height, weight and waist / hip circumference, blood tests to measure insulin and glucose and fats, and a DXA scan (similar to that routinely used to measure bone density) to measure total body fat. Patients will be followed up for 1 year after starting treatment; assessments will take place at baseline, 6 and 12 months. We hypothesize that we will see increases in body fat, glucose and insulin levels in patients taking antiresorptive treatments for osteoporosis, and vice versa.
