Priority 22 from the Contraception PSP

UNCERTAINTY: What are the health risks (osteoporosis, bone fracture) of using contraceptive injections, and do these increase with duration of use or vary with age of use?  (JLA PSP Priority 22)
Overall ranking 22
JLA question ID 0049/22
Explanatory note The June 14 Systematic review evaluated RCTs the outcomes assessed are bone mineral density assessed by scan, the hormone injection seems to reduce bone density. The same authors then conducted a systematic review  of non random studies concluded that there was an increased risk of bone fracture in women who had used the  contraceptive injection. This evidence was of moderate quality (Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.)

Original uncertainty examples

“I've been on the Depo injection for over a decade now, and it's wonderful, but doctors keep telling me I can't stay on it- I have no familial risk of osteoporosis, have a good diet, and have never broken a bone, why am I being bullied into having periods when I don't want them?” (Patient)  ~  “What is the evidence about bone mineral density and prolonged use of Depo-how can we best advise women who want to use Depo into their 40's?” (HCP)
