  abstract  = {Background: There is an increasing awareness of the impact of parental risk perception on the weight course of the child and the parent's readiness to engage in preventive efforts, but only less is known about factors related to the parental perception of the right time for the implementation of preventive activities. The aim of this study was to examine parental perceptions of the appropriate time to engage in child weight management strategies, and the factors associated with different weight points at which mothers recognize the need for preventive actions. Methods: 352 mothers with children aged 2-10 years took part in the study. We assessed mothers' perceptions of the actual and preferred weight status of their child, their ability to identify overweight and knowledge of its associated health risks, as well as perceptions of the right time for action to prevent overweight in their child. A regression analysis was conducted to examine whether demographic and weight related factors as well as the maternal general risk perception were associated with recognizing the need to implement prevention strategies. Results: Although most of the parents considered a BMI in the 75th to 90th percentile a valid reason to engage in the prevention of overweight, 19\% of the mothers were not willing to engage in prevention until their child reached the 97th percentile. Whereas the child's sex and the identification of an elevated BMI were significant predictors for parents' recognition of the 75th percentile as right point to engage in prevention efforts, an inability to recognize physical health risks associated with overweight silhouettes emerged as a significant factor predicting which parents would delay prevention efforts until a child's BMI reached the 97th percentile. Conclusion: Parental misperceptions of overweight and associated health risks constitute unfavorable conditions for preventive actions. Feedback on the health risks associated with overweight could help increase maternal readiness for change.},

  abstract  = {Background Attrition is a serious problem in intervention studies. The current study analyzed the attrition rate during follow-up in a randomized controlled pediatric weight management program (EPOC study) within a tertiary care setting. Methods Five hundred twenty-three parents and their 7-13-year-old children with obesity participated in the randomized controlled intervention trial. Follow-up data were assessed 6 and 12 months after the end of treatment. Attrition was defined as providing no objective weight data. Demographic and psychological baseline characteristics were used to predict attrition at 6- and 12-month follow-up using multivariate logistic regression analyses. Results Objective weight data were available for 49.6 (67.0) \% of the children 6 (12) months after the end of treatment. Completers and non-completers at the 6- and 12-month follow-up differed in the amount of weight loss during their inpatient stay, their initial BMI-SDS, educational level of the parents, and child's quality of life and well-being. Additionally, completers supported their child more than non-completers, and at the 12-month follow-up, families with a more structured eating environment were less likely to drop out. On a multivariate level, only educational background and structure of the eating environment remained significant. Conclusions The minor differences between the completers and the non-completers suggest that our retention strategies were successful. Further research should focus on prevention of attrition in families with a lower educational background.},

  abstract  = {Background: Research concerning child's food intake have considered various influencing factors, for example parental feeding strategies, demographic and weight factors. At this time, however, there are few findings that explore these factors simultaneously. Accordingly, the aim of this study was to test a structural equation model regarding the associations between maternal feeding strategies and child's food intake. Methods: 556 mothers and their children between 1 and 10 years of age participated in this crosssectional study. Besides socio-demographic and weight data, the mothers were asked about their feeding strategies as well as their child's food intake. Results: The well-fitting model explained 73\% of the variance in the child's consumption of healthy and 34\% of unhealthy food. In addition to the effect of the mother's social status and the child's age, a rewarding and modeling feeding behavior significantly influenced the child's food intake. Conclusion: The results highlight the relevance of maternal feeding behavior on the child's food intake. In terms of preventing eating- or weight-related problems, the findings indicate the usefulness of training parents in explicit modeling behavior and avoiding food as a reward.},

  abstract  = {Die Etablierung eines gesunden Ern{\"a}hrungsverhaltens unserer Kinder ist die wichtigste Voraussetzung f{\"u}r ihre k{\"o}rperliche, kognitive und emotionale Entwicklung. Dabei sind neben einer genetischen Disposition und kulturellen Gegebenheiten vor allem die Einfl{\"u}sse der jeweiligen Betreuungspersonen ausschlaggebend. Die Eltern steuern sowohl direkt (durch Aufforderungen, Verbote u.{\"a}.) als auch indirekt (durch die F{\"o}rderung eigenverantwortlicher Entscheidungen u.{\"a}.) das Ern{\"a}hrungsverhalten ihres Kindes. Untersuchungen zum m{\"u}tterlichen Steuerungsverhalten konzentrierten sich bisher vorwiegend auf die Betrachtung direkter Strategien sowie auf altershomogene und sozial besser gestellte Gruppen. Aufgrund m{\"o}glicher Verzerrungen durch die Betrachtung einzelner Ausschnitte des Zusammenhangs zwischen Steuerung und Ern{\"a}hrung wurde in der vorliegenden Arbeit ein Gesamtmodell spezifiziert, welches den Zusammenhang zwischen elterlicher Steuerung und kindlicher Ern{\"a}hrung unter Ber{\"u}cksichtigung von Sozial- und Gewichtsfaktoren abbildet. Dazu wurden drei Erhebungen mit insgesamt {\"u}ber 900 M{\"u}ttern 1 - 10-j{\"a}hriger Kinder durchgef{\"u}hrt. Innerhalb dieser Untersuchungen ist es gelungen, erstmalig ein deutschsprachiges Instrument zur Messung elterlicher Steuerungsstrategien in der Essenssituation (ISS) zu entwickeln. Die Analysen zeigten, dass bisher nur selten untersuchte Strategien, wie das explizite Bem{\"u}hen um Vorbildwirkung und das Erlauben von eigenverantwortlichen Entscheidungen des Kindes, von den M{\"u}ttern h{\"a}ufig angewandt werden. Die Analyse des komplexen Wirkungsgef{\"u}ge von Steuerung, kindlicher Ern{\"a}hrung sowie sozialer und gewichtsbezogener Faktoren zeigte weiterhin, dass neben stabilen Faktoren, wie dem m{\"u}tterlichen Status und dem Alter des Kindes, ein entscheidender Anteil der m{\"u}tterlichen Steuerungsstrategien f{\"u}r die kindliche Ern{\"a}hrung verantwortlich ist. Die berichteten Ergebnisse zeigen auf, wie relevant die gemeinsame Betrachtung von gesunden und problematischen Nahrungsmitteln sowie die den Zusammenhang zwischen Steuerung und Ern{\"a}hrung beeinflussenden Faktoren innerhalb eines Modells ist. Zusammengefasst scheint vor allem die Steuerung durch Belohnung von und mit bestimmten Nahrungsmitteln eine f{\"u}r das kindliche Ern{\"a}hrungsverhalten und das {\"U}bergewichtsrisiko besonders kritische Strategie zu sein. Dies ist umso bedeutender, als bisherige Untersuchungen dieses Verhalten h{\"a}ufig in restriktive Strategien integriert betrachteten. Die separate Analyse wies jedoch darauf hin, dass vor allem die belohnenden Verhaltensanteile relevant sind. Dies zeigt, dass es f{\"u}r die Entwicklung einer gesunden kindlichen Ern{\"a}hrung tats{\"a}chlich ver{\"a}nderbare Verhaltensweisen gibt, die Eltern in Pr{\"a}ventionsprogrammen oder anderen mit Kursen zum kindlichen Wohl assoziierten Einrichtungen vermittelt werden k{\"o}nnen.},
