OBJECTIVES: To evaluate knowledge about, attitudes towards and use of hormone replacement therapy (HRT) in Norwegian women - and to compare self-reported use with sales statistics of HRT in the Nordic countries during recent years. MATERIAL AND METHODS: Random samples of Norwegian women age 16-79 were interviewed by the Central Bureau of Statistics in 1994 (n=737), in 1996 (n=665) and in 1998 (n=680). Statistics on the sale of estrogen were provided by the Norwegian Medical Depot and Nordic Council on Medicines. RESULTS: One in three women had received information about HRT during the last 2 years (1994), mainly through weekly magazines and physicians. The proportion answering in accordance with the prevailing view of HRT's effects ('correct knowledge') varied from 36.4 to 47.2%. Those informed by a physician possessed correct knowledge, had positive attitudes towards HRT and were willing to use HRT more often than women informed through other channels. Women with a high level of education had received information and had correct knowledge more often than others, but they were still less willing to use HRT and did not use HRT more often than the less educated. In the age group 45-69 years the use of HRT was 16.3% in 1994, 19.1% in 1996 and 19. 1% in 1998 (P=0.421, trend). In addition to received information, attitudes towards and knowledge about estrogen were the most important factors predicting use of HRT after adjusting for other variables. According to sales figures, the use of systemic estrogen in Norway has increased more than 360% since 1990. Although no other Nordic country has experienced a corresponding increase, Iceland had the highest sales figures in 1997. CONCLUSIONS: Based on the limited proportion of women receiving information on HRT and the ambivalence found in groups of educated women, we suggest that more and better information should be given middle-aged women to make them better able to make informed choices regarding use of HRT.
