The use of proton pump inhibitors has been associated with an increased risk of hip fracture. The authors of a recent study [1] sought to further explore the relation between duration of exposure to proton pump inhibitors and osteoporosis-related fractures. They used administrative claims data to identify patients with a fracture of the hip, vertebra, or wrist between April 1996 and March 2004. Cases were each matched with 3 controls based on age, sex, and comorbidities. They calculated adjusted odds ratios (OR) for the risk of hip fracture and all osteoporosis-related fractures for durations of proton pump inhibitor exposure ranging from 1 or more years to more than 7 years.

Quantitative ultrasound has been shown to predict risk of fracture in various populations. However, this ability may be modified by the presence of previous fracture in very frail older people. The authors of a recent study [1] assessed bone strength by quantitative ultrasound (QUS) and clinical risk factors at baseline for 1 982 institutionalised older people. Fractures were ascertained for 2 years from baseline and validated by X-ray reports.

Data from case-control studies as well as from a cross-sectional study suggest an independent association between Parkinson’s disease (PD) and prevalent lower bone mineral density. Among older PD patients in randomized trials, control group participants experienced bone mineral density (BMD) loss exceeding 4% per year, suggesting that PD is associated with rapid incident bone loss. Retrospective and case-control studies have suggested that PD increases risk for fractures. However, prospective data are limited. The objective of this study [1] was to examine the association of PD with bone loss and fractures in older men. This prospective cohort study analyzed data from 5937 community dwelling men aged >65 years at six clinical centers of the Osteoporotic Fractures in Men (MrOS) study. At baseline and visit two (mean interval 4.6 years), community-diagnosed PD was ascertained by self-report and hip BMD was measured using dual energy x-ray absorptiometry (DXA). Incident fractures were self-reported. Fractures and deaths were centrally adjudicated.

Cardiovascular disease and osteoporotic fractures are two major public health problems. Cardiovascular disease and osteoporosis coexist in women: progression of aortic calcifications has been associated with faster bone loss. Low BMD has been shown to predict cardiovascular events and cardiovascular mortality, whereas the association between the extension of aortic calcifications and hip fracture risk is controversial. In contrast to these findings in women, few studies concern the relationship between osteoporosis and cardiovascular disease in men.

Some studies have reported associations between cardiovascular diseases (CVD) and bone mineral loss. Osteoclast regulatory factors can affect vascular calcifications, and a high blood pressure can induce abnormalities in calcium metabolism and increase bone mineral loss in women. Low bone mineral density is not only an important predictor of osteoporotic fracture, but is also a risk factor for mortality.
