After we demonstrated a substantial drop in postmenopausal hormone therapy (HT) in France after 2002, we sought to compare health characteristics assessed before menopause and reasons for beginning treatment among women who started postmenopausal HT before and after this year.
Among participants of the GAZEL (GAZ and ELectricité) cohort of employees of the French national power company, we studied 1,229 women who reached menopause before 2002 and 562 women who reached menopause after 2002. We analyzed HT use among these newly postmenopausal women before and after 2002 and its relations to self-rated health, simple and troublesome hot flushes, and various other symptoms before menopause.
After 2002, compared with before 2002, women starting HT were more likely to have reported troublesome hot flushes before menopause (odds ratio, 2.3; 95% CI, 1.0-5.4). The groups of new HT users did not differ significantly except for health characteristics. Significantly higher proportions of women starting HT reported using it for hot flushes (68.1% vs 52.9%, P = 0.02) and sleep disorders (11.1% vs 2.8%, P = 0.001) and a significantly lower proportion of women starting HT reported using it for osteoporosis prevention (12.5% vs 43.9%, P < 0.001) after 2002 than before 2002.
After 2002, HT tended to be prescribed for more severe hot flushes, but almost one third of prescriptions were still written for reasons not linked to hot flushes. Doctors seem to be following recommendations to not use HT as a first-line treatment of osteoporosis.
