The overall objective with the study was to contribute to the scientific basis for dietary and life strategies, policies and dietary guidelines to infants and young children in Denmark and with special focus on prevention of obesity and diet related chronic diseases such as type 2 diabetes, ischemic heart disease and osteoporosis.
The SKOT I study is a prospective cohort study monitoring healthy young children from 9 to 36 months of age. In 2007, 2211 families from Copenhagen were randomly selected through the National Civil Registry and invited to participate in the study by letter. The participants were invited to three examinations at 9 months ±2 weeks, 18 months ±4 weeks and 36 months ±3 months. A total of 330 children are included in the study, where 312 have completed the 9 months examination, 291 completed the 18 months examination and 263 completed the 3-year examination. All examinations took place at Department of Nutrition, Exercise and Sports, Frederiksberg Denmark. The examinations involved collecting a broad spectrum of data. Following data were collected: anthropometry (weight, height, age- and sex-specific Z-scores for body composition, triceps and subscapularis skinfolds), background interview (concerning e.g. infant feeding, household income, the parent's educational level, allergy and chronic diseases), blood pressure (systolic, diastolic and mean arterial pressure), faeces- and urine sample, blood samples (9 and 36 months), Bio impedance analysis (36 months), 7 day diet registration, general questionaire (concerning e.g. sleep, daycare, attendance and use of screen devices), psychomotor questionnaire (motoric development), 7 day physical activity monitoring and dual energy x-ray absorptiometry scan (36 months).
