Swedish Mammography Cohort - clinical subcohort Uppsala

From 2003 through 2009 participants in the Swedish Mammography Cohort below age 85 years and living in the town of Uppsala were randomly selected and invited to participate in a clinical subcohort. Of the 8,311 invited women 65% answered the received diet, lifestyle, and physical activity questionnaire and 60%, 5,032 women, participated in the health examination. Samples are available for 5022 women. The health examination included weight, height, waist, hip, and blood pressure measurements, and body composition measurement using a dual energy X-ray absorptiometry (DEXA) scan. Samples of fasting blood and urine in addition to adipose tissue were also collected at the health exam.

A subset of the women visiting the clinic completed additional food and physical activity  questionnaires in addition to wearing a physical activity monitor and complete a 7-day activity record. A second subset of women visiting the clinic completed a questionnaire on sun exposure in conjunction with a blood sample collected both during winter and summer months.

A second round of health examination including biological sample collection (blood, urine, adipose tissue, but also faeces), and diet and lifestyle questionnaire, is ongoing for this clinical subcohort since January 2015.
