Design outcomes

Primary

Measure	Time frame
BMI and waist circumference (WC) of the participating children and their parents will be compared between the intervention group and the control group. Four-year-old children's and their parents' BMI and WC are primary outcomes, and will be used as indicators of obesity status. Nurses at the CHC measure children's and parents' height and weight by instruments which have been validated for measurement errors. Data from parents at baseline are self-reported. In parents attending CHC waist circumference (WC) is measured by nurses using a measuring tape. In 4-years old children attending CHC WC is also measured by nurses using a measuring tape.	—

Secondary

Measure	Time frame
Secondary outcomes are PA, eating habits (fruits, vegetables, fish, French fries, sugared drinks, leeway and regularity of eating). The eating habits of children and parents were assessed with a validated semi-quantitative food frequency questionnaire (FFQ). The FFQ includes questions about habitual dietary intake of certain food items as well as intake of beverages. The parent FFQ version includes 81-items and the child 79-items, and is complemented by questions about regularity of meals. The questions in the FFQs are intended to serve as indicators of healthy and unhealthy eating habits. Differences in physical activity (PA) between mothers and fathers in the intervention group and their counterparts in the control group are investigated by the Baecke questionnaire, which has been shown to have good validity. Differences in PA between children in the intervention group and those in the control group are furthermore investigated objectively by an accelerometer for the period of one week, when children reached the age of 4. Mothers' and fathers' PAs are investigated at enrolment and again at 4 years of children's age, while the children's PA is examined only at 4 years of age.	—
