- BackgroundThe Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS (IDEFICS) study investigated the aetiology of childhood obesity and developed a primary prevention programme. MethodsPre-intervention adherence to key behaviours related to childhood obesity, namely water/sweetened drink, fruit/vegetable consumption, daily TV time, physical activity, family time and adequate sleep duration, was measured at baseline. Adherence to international recommendations was converted into a composite score ranging from 0 (none) to 6 (adhering to all). Data on adherence were available for 7,444 to 15,084 children aged 2-9.9years, depending on the behaviour. By means of multi-level logistic regression models adjusted for age, sex and country, we calculated odds ratios (OR) and 95% confidence intervals (CI) to estimate the relationship between adherence to these recommendations and the risk of being overweight/obese. ResultsAdherence ranged from 15.0% (physical activity) to 51.9% (TV time). As adherence increased, a lower chance of being overweight/obese was observed; adhering to only one key behaviour (score=1) meant an OR=0.81 (CI: 0.65-1.01) compared with non-adherence (score=0), while adhering to more than half of the key behaviours (score4) halved the chance for overweight/obesity (OR=0.54, CI: 0.37-0.80). Adherence to physical activity, TV and sleep recommendations was the main driver reducing the chance of being overweight. Overweight/obese children were more likely not to adhere to at least one of the recommended behaviours (19.8%) than normal-weight/thin children (12.9%) ConclusionThe selected key behaviours do not contribute equally to a reduced chance of being overweight. Future interventions may benefit most from moving more, reducing TV time and getting adequate sleep. (c) 2015 World Obesity

- Background:Various twin studies revealed that the influence of genetic factors on psychological diseases or behaviour is more expressed in socioeconomically advantaged environments. Other studies predominantly show an inverse association between socioeconomic status (SES) and childhood obesity in Western developed countries. The aim of this study is to investigate whether the fat mass and obesity-associated (FTO) gene interacts with the SES on childhood obesity in a subsample (N=4406) of the IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS) cohort.Methods:A structural equation model (SEM) is applied with the latent constructs obesity, dietary intakes, physical activity and fitness habits, and parental SES to estimate the main effects of the latter three variables and a FTO polymorphism on childhood obesity. Further, a multiple group SEM is used to explore whether an interaction effect exists between the single nucleotide polymorphism rs9939609 within the FTO gene and SES.Results:Significant main effects are shown for physical activity and fitness (standardised [betacrc ](s) = -0.113), SES ([betacrc ](s) = -0.057) and the FTO homozygous AA risk genotype ([betacrc ](s) = -0.177). The explained variance of obesity is ~9%. According to the multiple group approach of SEM, we see an interaction between SES and FTO with respect to their effect on childhood obesity (Δχ(2)=7.3, df=2, P=0.03).Conclusion:Children carrying the protective FTO genotype TT seem to be more protected by a favourable social environment regarding the development of obesity than children carrying the AT or AA genotype.International Journal of Obesity advance online publication, 23 September 2014; doi:10.1038/ijo.2014.156.

- This study analyzes peer effects on childhood obesity using data from the first two waves of the IDEFICS study, which applies several anthropometric and other measures of fatness to approximately 14,000 children aged two to nine participating in both waves in 16 regions of eight European countries. Peers are defined as same-sex children in the same school and age group. The results show that peer effects do exist in this European sample but that they differ among both regions and different fatness measures. Peer effects are larger in Spain, Italy, and Cyprus - the more collectivist regions in our sample - while waist circumference generally gives rise to larger peer effects than BMI. We also provide evidence that parental misperceptions of their own children's weight goes hand in hand With fatter peer groups, supporting the notion that in making such assessments, parents compare their children's weight with that of friends and schoolmates.

- IntroductionFrom April 2008 to August 2010 the Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS (IDEFICS) intervention aimed to encourage healthier diets, higher physical activity levels and lower stress levels among European children and their families. While the intervention was intended to improve children's health, we also wished to assess whether there were unwelcome aspects or negative side-effects. Therefore all parents of children who participated in the IDEFICS intervention were asked for their views on different aspects of the intervention. MethodsA total of 10,016 parents of children who participated in the IDEFICS survey and who were involved in the intervention were invited to complete a questionnaire on positive and negative impacts of the intervention. Responses to each of the statements were coded on a four point Likert-type scale. Demographic data were collected as part of the baseline (T-0) and first follow-up (T-1) surveys; intervention exposure data was also collected in the T-1 follow-up survey. Anthropometric data was collected in the same surveys, and child's weight status was assessed according to Cole and Lobstein. After initial review of the univariate statistics multilevel logistic regression was conducted to analyse the influence of socio-economic factors, child's weight status and intervention exposure on parental responses. ResultsIn total 4,997 responses were received. Approval rates were high, and few parents reported negative effects. Parents who reported higher levels of exposure to the intervention were more likely to approve of it and were also no more likely to notice negative aspects. Less-educated and lower income parents were more likely to report that the intervention would make a lasting positive difference, but also more likely to report that the intervention had had negative effects. Parents of overweight and obese children were more likely to report negative effects - above all, that the intervention had made their child feel as if he/she was fat or overweight.' ConclusionWhile the results represent a broad endorsement of the IDEFICS intervention, they also suggest the importance of vigilance concerning the psychological effects of obesity interventions on overweight and obese children.
