Description
Three pages of this questionnaire were devoted to physical activity, the main focus of the project. Both previously validated and newly developed questions were used in order to estimate energy expenditure and to distinguish between constant low-level activity and short-term peak activity. We used a new rating scale for self-reports of time spent on different intensity levels of physical activity (and inactivity) during a typical day, allowing estimation of total energy expenditure on an interval scale level. This scale has been shown to be both valid and reliable. Seven pages contained questions about diet, using a 63-item validated semi-quantitative food frequency questionnaire that allows estimation of total energy intake and calorie adjustment. Supplementary questions were asked about intake of fried food, detailed pattern of alcohol intake, dietary supplements and use of health food preparations. Two pages had questions about anthropometrical measures, including height, weight (birth weight, current weight, and weight fluctuations), waist and hip measures (allowing calculations of BMI, le
