BACKGROUND There is an increase in the prevalence of overweight and obese children. Genetic and environmental factors are contributing factors but the influence of parental nutritional state on early manifestation of overweight is not well characterised. AIM OF THE STUDY To systematically investigate the impact of parental BMI on the manifestation of(More)
OBJECTIVES: To identify the major risk factors of overweight and obesity in prepubertal children.DESIGN: Cross-sectional study.SETTING: In all, 32 primary schools in Kiel (248 000 inhabitants), northwest Germany.SUBJECTS: A total of 2631 5–7-y-old German children and their parents.MAIN OUTCOME MEASURES: Weight status, socio-economic status (SES), parental(More)
BACKGROUND The use of bioelectrical impedance phase angle has been recommended as a prognostic tool in the clinical setting, but published reference data bases are discrepant and incomplete (eg, they do not consider body mass index [BMI], and data are lacking for children). METHODS Phase angle reference values stratified by age, sex, and BMI were(More)
BACKGROUND Bioelectrical impedance analysis (BIA) gives resistance (R) and reactance (Xc). R and Xc normalized for body height (H) can be plotted as a bivariate vector (H(2)/Xc versus H(2)/R). Vector BIA is useful for studying the determinants of BIA results. OBJECTIVE We investigated the effect of age on BIA results and its relevance to body-composition(More)
Current anthropometric indices for health risk assessment are indirect measures of total or visceral body fat mass that do not consider the inverse relationship of lean body mass to metabolic risk as well as the non-linear relationship between central obesity and insulin resistance. We examined a new anthropometric index that reflects the relationship of(More)
Übergewicht und Adipositas sowie auch deren Folgeerkrankungen sind heute epidemisch. Wir sind eine „übergewichtige Gesellschaft“, welche sich auf dem Weg in eine „adipöse Gesellschaft“ befindet. Deshalb sind sowohl eine nachhaltig wirksame Behandlung als auch eine Public-Health-Strategie zur Prävention der Adipositas notwendig. Beide Strategien sind idealer(More)
There have been only a few controlled studies on the prevention of overweight and obesity in children and adolescents. These studies differ in relation to strategy, setting, duration, focus, variables of outcome and statistical power, and therefore do not allow general conclusions to be made about the value of preventive measures. All school-based(More)
In Western societies, there is an inverse socioeconomic status (SES) gradient in overweight, but its onset is unknown. It was the aim of this study to assess the onset of the SES gradient in overweight children from birth to age 5-7 y. This was a cross-sectional and longitudinal study of 1326 children [668 boys and 658 girls; median age, 6.3 y;(More)
Aims:Prevention of obesity is a public health agenda. There are only few longitudinal studies on prevention of overweight in children. The Kiel Obesity Prevention Study (KOPS) intends to characterise the determinants of childhood overweight and the effect of preventive measures within schools as well as within families.Methods:Between 1996 and 2005, KOPS(More)
AIM To evaluate the feasibility and 4-year outcome of school-based health promotion on overweight among 6-10-year-old children. METHODS Four-year follow-up data of 344 children participating in health promotion (I) as part of the Kiel Obesity Prevention Study (KOPS) at age 6 years, compared with 4-year changes in 1420 non-intervention children (NI).(More)
