Brief Summary:
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.

Detailed Description:
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).

growth and development
Growth and development of a random sample of healthy Danish infants

Primary Outcome Measures :
  1. Change in anthropometric measurements in periods of early childhood. [ Time Frame: 9, 18 and 36 months of age ]
    Composite outcome consisting of body weight, height, body mass index (BMI) and BMI z-scores, waist-, upper arm- and head circumference, skinfold thickness measured at subscapularis and triceps.

  2. Body composition in early childhood [ Time Frame: 36 months of age ]
    Body composition is measures by Dual-energy X-ray Absorptiometry and bio impedance. Fat mass, fat mass index (kg/m2), fat free mass index (kg/m2) are calculated.

  3. Metabolic syndrome score in early life [ Time Frame: 9 and 36 months of age ]
    Composite outcome consisting of triglycerides, high lipoprotein (HDL) and glucose measured in plasma/serum, waist circumference and blood pressure.

  4. Diet in periods of early life [ Time Frame: 9, 18 and 36 months of age ]
    The diet is recorded using self-reported 7-day record questionnaire.

Secondary Outcome Measures :
  1. Breastfeeding duration in infancy and early childhood [ Time Frame: 9, 18 and 36 months of age ]
    Questionnaire used for assessment of exclusive and partially breastfeeding.

  2. Insulin like growth factor at 9 and 36 months of age [ Time Frame: 9 and 36 months of age ]
    Insulin like growth factor-1 and insulin like growth factor binding protein-3 concentrations in plasma.

  3. Physical activity, sedentary behavior and sleep in early childhood [ Time Frame: 9, 18 and 36 months of age ]
    Physical activity and sedentary behavior measured by ActiGrafph GT3X accelerometer, recording for 24 hours in 7 days at 36 months of age. Information on outdoor activity, sedentary behavior and night sleep are collected through questionnaires at 9, 18 and 36 months of age.

  4. Bone mass in 3-year-old children [ Time Frame: 36 months of age ]
    Bone mass is measured by Dual-energy X-ray Absorptiometry

  5. Vitamin D status in infancy [ Time Frame: 9 months of age ]
    25-hydroxyvitamin D concentrations are analysed in blood samples at 9 months of age.

  6. Allergy and chronic diseases [ Time Frame: 9 and 36 months of age ]
    Assessment of diseases by questionnaires

  7. Appetite hormones in infancy [ Time Frame: 9 months of age ]
    Leptin and adiponectin concentrations measured from blood samples

  8. Change in gut microbiota [ Time Frame: 9, 18 and 36 months of age ]
    Microbiota in the faeces analysed using polymerase chain reaction (PCR)

  9. Achievement of milestones [ Time Frame: 9 and 36 months of age ]
    Achievement of age-specific milestones by questionnaires; WHO questionnaires at 9 and 36 months of age and Ages & Stages Questionnaires (ASQ) at 36 months of age

  10. Metabolomics in the urine [ Time Frame: 9, 18 and 36 months of age ]
    Metabolomics analysed using urine samples.

Biospecimen Retention:   Samples With DNA
Urine, faeces, white cells, plama/serum
