Description
The Swedish Mammography Cohort (SMC) is a large population-based cohort of over 60,000 women in the counties of Uppsala and Västmanland. All women born 1914-1948 who were residing in Västmanland and Uppsala County and in the years 1987-1990 received an invitation to participate in a mammography screening programme were asked to answer a questionnaire about diet and lifestyle. Approximately 66,000 women answered the questionnaire. In the autumn 1997, a second survey was sent to these women to update the information about their eating habits. Additional follow-ups were done 2008/2009 and 2019. The study examine associations of environmental/modifiable risk factors with several cancer sites (e.g., breast, colorectal, endometrium, ovary, and renal cell cancer), myocardial infarction, stroke, osteoporosis, cataracts, as well as death causes. The study has a longitudinal design, and to complement the update on exposure data record linkages to the nationwide Cancer Register, the In-Patient Register, and the Cause of Death Register and Population Register are also done.
