Description

The Swedish Mammography Cohort (SMC) is a large population-based cohort of over 60,000 women in the counties of Uppsala and Västmanland which is performed by the National Institute of Environmental Medicine, Karolinska Institutet . The general aim is to assess relationships between a number of modifiable factors (diet, vitamin supplement use, physical activity, smoking, alcohol, body weight, other anthropometric measures etc.) and the occurrence of several major chronic diseases. 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. The study examine associations of environmental/modifiable risk factors with several cancer sites (e.g., breast, colon, rectum, endometrium, ovary, and renal cell cancer), myocardial infarction, stroke, osteoporos

Sampling procedure

Total universe/Complete enumeration
From 1987 to 1990, all women who lived in the Uppsala County of central Sweden and were born between 1914-1948 and all women who lived in the adjacent Västmanland County and were born between 1917-1948 received an invitation by mail to participate in a mammography screening program. A total of 66,651 (74% of the source population) returned a completed questionnaire on diet, weight, height, parity, and education. In 1997, a follow-up questionnaire was sent to all cohort members who were still living in the study area. Further follow-up was made during 2008-2009. The 2009 questionnaire was sent only to those who answered 2008.
