While the use of alcohol and marijuana is widespread among 16-18 year olds the use of  other substances is much less common. Those youth who do use these substances are often coping with negative experiences in their lives and need the support of family, schools, peers and their communities. Find the fact sheet here.

Pharmacotherapy. 2010; 30(5):442–452.

Study Objective: To compare the cardiovascular and metabolic effects of medroxyprogesterone acetate (MPA) with those of conjugated equine estrogen (CEE) as single-hormone therapies in women who underwent hysterectomy with bilateral ovariectomy. Design:  Secondary analysis of a 12–month, double-blind, randomized, parallel-therapy trial. Setting: Four teaching hospitals and one community hospital in Vancouver, Canada. Participants: Thirty-three healthy […]

Physicians and menstruating women often ask pharmacists for recommendations about menstrual cycle–related problems. Progesterone and medroxyprogesterone may provide physiology-based treatment, but official indications in menstruating women in Canada are minimal. To describe pharmacists’ responses to vignette-based questions about the treatment of common clinical problems in menstruating women and review evidence-based therapies.  A pharmacist interviewer administered […]

We address the crucial and challenging task of anticipating the resources needed to recruit eligible participants for research. We provide our analysis of various recruitment strategies and their cost-effectiveness in our experience in enrolling 610 women for an observational study on ovulation. We assess the cost-effectiveness and success of multiple recruitment strategies we employed and […]

Previous research has shown that underlying dietary patterns are related to the risk of many different adverse health outcomes, but the relationship of these underlying patterns to skeletal fragility is not well understood. The objective of the study was to determine whether dietary patterns in men (ages 25-49, 50+) and women (pre-menopause, post-menopause) are related […]

This population-based study of mid-aged Canadians assessed awareness of diagnosis by bone mineral density (BMD) following dual-energy X-ray absorptiometry (DXA) testing and compared the effects of feedback only to the physician with direct-to-participant feedback. Poor recall of osteoporosis results was observed irrespective of the feedback destination, but direct-to-participant feedback improved recall of borderline or normal […]

Cross-sectional studies have found associations among elevated cognitive dietary restraint (CDR), increased ovulatory disturbances, and lower bone mass, possibly mediated by cortisol. To determine whether healthy young women with higher CDR have more menstrual cycles with subclinical ovulatory disturbances (SOD), elevated 24-h urinary free cortisol (UFC), and less positive 2-yr areal bone mineral density change […]

The objectives of the study were to develop bone mineral density (BMD) reference norms and BMD Z-scores at various skeletal sites, to determine whether prior fracture and/or asthma were related to BMD, and to assess possible geographic variation of BMD among Canadian youth aged 16–24 yr. Z-Scores were defined as the number of standard deviations […]

Peak bone mass from longitudinal data: implications for the prevalence, pathophysiology, and diagnosis of osteoporosis. Journal of Bone Mineral Research, 25(9):1948-57.

We estimated peak bone mass (PBM) in 615 women and 527 men aged 16 to 40 years using longitudinal data from the Canadian Multicentre Osteoporosis Study (CaMos). Individual rates of change were averaged to find the mean rate of change for each baseline age. The age range for PBM was defined as the period during […]

Prior J.C., Hitchcock, C. L. (2010) The endocrinology of perimenopause: need for a paradigm shift. Frontiers in Bioscience (Schol Ed) 1 (3):474-86.

Perimenopause, rather than a time of declining estrogen, is characterized by three major hormonal changes that may begin in regularly menstruating women in their mid-thirties: erratically higher estradiol levels, decreased progesterone levels (in normally ovulatory, short luteal phase or anovulatory cycles), and disturbed ovarian-pituitary-hypothalamic feedback relationships. Recent data show that approximately a third of all […]

Langsetmo L, Leslie WD, Zhou W, Goltzman D, Kovacs CS, Prior J, Josse R, Olszynski WP, Davison KS, Anastassiades T, Towheed T, Hanley DA, Kaiser S, Kreiger N; CaMOS Research Group (2010) Using the same bone density reference database for men and women provides a simpler estimation of fracture risk. Journal of Bone Mineral Research 25(10):2108-14.

Although low bone mineral density (BMD) predicts fractures, there are postulated sex differences in the fracture “threshold.” Some studies demonstrate a higher mean BMD for men with fractures than for women, whereas others note similar absolute risk at the same level of BMD. Our objective was to test the preceding observations in the population-based Canadian […]

Menopause 17(5):1010-6.

Most low-trauma fractures occur among women with osteopenic bone mineral density (BMD), a population considered to have moderate absolute fracture risk. Our purpose was to refine the fracture risk prediction in women with osteopenic BMD to determine the subgroups at lowest and highest risk. We included 2,588 women aged 50 to 90 years with osteopenic […]

Kalyan S, Prior JC (2010) Bone Changes and Fracture Related to Menstrual Cycles and Ovulation. Critical Reviews of Eukaryotic Gene Expression 20(3):213-33.

Women’s menstrual cycles and bone remodeling are linked in part by their co-dependency on the stress- and resource-associated variables that govern both of their cyclical natures. Therefore, it is not surprising that evolution has resulted in the same signaling molecules and pathways that regulate normal ovarian function to be involved in bone remodeling and turnover. […]

Seifert-Klauss V and Prior J.C (2010) Progesterone and Bone – Actions Promoting Bone Health in Women. Journal of Osteoporosis Oct 31;2010:845180.

Estradiol ( E 2 ) and progesterone ( P 4 ) collaborate within bone remodelling on resorption ( E 2 ) and formation ( P 4 ). We integrate evidence that P 4 may prevent and, with antiresorptives, treat women’s osteoporosis. P 4 stimulates osteoblast differentiation in vitro. Menarche ( E 2 ) and onset […]
