To study the fracture reducing potential of hormonal replacement therapy (HRT) in recent postmenopausal women in a primary preventive scenario.


Prospective controlled comprehensive cohort trial: 2016 healthy women aged 45-58 years, from three to 24 months past last menstrual bleeding were recruited from a random sample of the background population. Mean age was 50. 8+/-2.8 years, and the number of person years followed was 9335.3. There were two main study arms: a randomised arm (randomised to HRT; n=502, or not; n=504) and a non-randomised arm (on HRT; n=221, or not; n=789 by own choice). First line HRT was oral sequential oestradiol/norethisterone in women with intact uterus and oral continuous oestradiol in hysterectomised women.


After five years, a total of 156 fractures were sustained by 140 women. There were 51 forearm fractures in 51 women. By intention-to-treat analysis (n=2016), overall fracture risk was borderline statistically significantly reduced (RR=0.73, 95% CI: 0.50-1.05), and forearm fracture risk was significantly reduced (RR=0.45, 95% CI: 0.22-0.90) with HRT. Restricting the analysis to women who had adhered to their initial allocation of either HRT (n=395) or no HRT (n=977) showed a significant reduction in both the overall fracture risk (RR=0.61, 95% CI: 0.39-0.97) and the risk of forearm fractures (RR=0.24, 95% CI: 0.09-0.69). Compliance with HRT was 65% after five years.


It is possible to reduce the number of forearm fractures and possibly the total number of fractures in recent postmenopausal women by use of HRT as primary prevention.
