The nationwide ‘German Health Interview and Examination Survey for Children and Adolescents’ (KiGGS), conducted in 2003–2006, showed an increase in the prevalence rates of overweight and obesity compared to the early 1990s, indicating the need for regular monitoring. Recently, a follow-up—KiGGS Wave 1 (2009–2012)—was carried out as a telephone-based survey, providing parent-reported height and weight from 5155 children aged 4–10 years. Since parental reports lead to a bias in prevalence rates of weight status, a correction is needed. From a subsample of KiGGS Wave 1 participants, measurements for height and weight were collected in a physical examination. In order to correct prevalence rates derived from parent reports, weight status categories based on parent-reported and measured height and weight were used to estimate a correction formula according to an established procedure. The corrected prevalence rates derived from KiGGS Wave 1 for overweight, including obesity, in children aged 4–10 years in Germany showed that stagnation is reached compared to the KiGGS baseline study (2003–2006).
What is Known:
• In the last decades, prevalence of overweight and obesity has risen. Now a days, the prevalence seems to be stagnating.
• In Germany, prevalence estimates of overweight and obesity are only available from regional or non-representative studies.
What is New:
• This article gives an update for prevalence rates of overweight and obesity amongst children aged 4–10 years in Germany based on a nationwide and representative sample.
• Results show that stagnation in prevalence rates for overweight in children in Germany is reached.
