For practical and financial reasons, self-reported instead of measured height and weight are often used. The aim of this study is to evaluate the validity of self-reports and to identify potential predictors of the validity of body mass index (BMI) derived from self-reported height and weight. Self-reported and measured data were collected from a sub-sample(More)
The use of parent-reported height and weight is a cost-efficient instrument to assess the prevalence of children's weight status in large-scale surveys. This study aimed to examine the accuracy of BMI derived from parent-reported height and weight and to identify potential predictors of the validity of BMI derived from parent-reported data. A subsample of(More)
Prevalence rates for overweight and obesity based on self-reported height and weight are underestimated, whereas the prevalence rate for underweight is slightly overestimated. Therefore a correction is needed. Aim of this study is to apply correction procedures to the prevalence rates developed on basis of (self-reported and measured) data from the(More)
BACKGROUND Current studies suggest that the beneficial effect of breastfeeding on overweight and obesity may have been largely overestimated. We examined the relationship between >4 months of full breastfeeding and overweight/obesity in children living in Germany. METHODS We analyzed retrospectively collected data on breastfeeding from children aged 3-17(More)
There is an error in the first sentence of the Results section in the Abstract. The correct sentence is: Adjusted analyses of the matched dataset (n = 8034) indicated that children who were breastfed for>4 months had a significant reduction in the odds of overweight (OR 0.81 [95% CI 0.71–0.92]) and obesity (OR 0.75 [95% CI 0.61–0.92]) compared to children(More)
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,(More)
Viele Kinder und Jugendliche in Deutschland wachsen in Familien mit Migrationshintergrund auf. Unterschiedliche kulturelle, religiöse und sprachliche Hintergründe beeinflussen ihr Verhalten in vielerlei Hinsicht. Der Zusammenhang zwischen Gesundheit und Migrationshintergrund kann sowohl positiv als auch negativ sein. Ziel der vorliegenden Arbeit war es,(More)
OBJECTIVE The use of reported instead of measured height and weight induces a bias in prevalence rates for overweight and obesity. Therefore, correction formulas are necessary. METHODS Self-reported and measured height and weight were available from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) baseline study(More)
