Early detection and prevention of overweight

Methods

The data collection is linked to the data-collection of a prospective study on infant feeding practices, which was carried out in the period 1977-1986 in Terneuzen. In this study data on infant feeding practices during the first 6 months were collected from all 2599 children born during this period in Terneuzen. These data contain information on e.g. birth weight, duration of breast- and/or formula feeding practices and smoking habits of the mother. In the first phase of the study this information has been completed with data on the growing pattern (length and weight) during the age of 0 to 15 years. These data were collected from the medical records at the municipal health services. All Dutch children receive periodical health examinations during the age of 0 to 14 years. These examinations are carried out according to a protocol at the infant centers and youth health care departments of the municipal health service centers. We traced 71% of the medical records.
In the second phase we traced the addresses of 78% of the 2599 children that were included in the study on infant feeding practices and who were in the mean time 17 to 26 years old. These young adults were asked to complete questionnaires on lifestyle habits and comorbidity related to overweight. In addition, a physical and laboratory examination was carried out to assess data on length, weight, cardiovascular risk factors and type 2 diabetes.
