Descriptive norms about condom use predict odds of using a condom during last sexual experience in a large, national survey of adolescents from Australia.

Background: Reducing sexually transmitted infections among adolescents is an important public health goal in Australia and worldwide. This study estimated the association between condom use during last heterosexual sexual experience with two descriptive norms among a large, national sample of secondary school students from Australia.

Methods: A large, national online survey of 14- to 18-year-olds in Australia was conducted in 2018; a sub-analysis of sexually active participants (n =2989) used multivariable logistic regression to estimate the relationships between condom use during last sexual experience and condom use norms.

Bone-loading exercises versus risedronate for the prevention of osteoporosis in postmenopausal women with low bone mass: a randomized controlled trial.

Purpose: This randomized controlled trial compared changes in bone mineral density (BMD) and bone turnover in postmenopausal women with low bone mass randomized to 12 months of either risedronate, exercise, or a control group.

Methods: Two hundred seventy-six women with low bone mass, within 6 years of menopause, were included in analysis. Treatment groups were 12 months of (a) calcium and vitamin D supplements (CaD) (control), (b) risedronate + CaD (risedronate), or (c) bone-loading exercises + CaD (exercise).

Examining effects of habitual physical activity and body composition on bone structure in early post-menopausal women: a pQCT analysis.

Unlabelled: After menopause, bones decline in structure and can break more easily. Physical activity can strengthen bones. This study investigated how activity and body composition can impact bone structure in post-menopausal women.

Patient and system factors associated with unassisted and injurious falls in hospitals: an observational study.

Background: Unassisted falls are more likely to result in injury than assisted falls. However, little is known about risk factors for falling unassisted. Furthermore, rural hospitals, which care for a high proportion of older adults, are underrepresented in research on hospital falls.

Protocol for a randomized controlled trial to compare bone-loading exercises with risedronate for preventing bone loss in osteopenic postmenopausal women.

Background: In the United States, over 34 million American post-menopausal women have low bone mass (osteopenia) which increases their risk of osteoporosis and fractures. Calcium, vitamin D and exercise are recommended for prevention of osteoporosis, and bisphosphonates (BPs) are prescribed in women with osteoporosis. BPs may also be prescribed for women with low bone mass, but are more controversial due to the potential for adverse effects with long-term use.
