- BACKGROUND/OBJECTIVES:Individual lifestyle behaviours have independently been associated with cardiovascular diseases (CVD) risk factors in children. This study aimed to identify clustered lifestyle behaviours (dietary, physical activity (PA) and sedentary indicators) and to examine their association with CVD risk factors in children aged 2-9 years.SUBJECTS/METHODS:Participants included 4619 children (51.6% boys) from eight European countries participating in the IDEFICS cross-sectional baseline survey (2007-2008). Insulin resistance, total cholesterol/high-density lipoprotein cholesterol ratio, triglycerides, sum of two skinfolds and systolic blood pressure (SBP) z-scores were summed to compute a CVD risk score. Cluster analyses stratified by sex and age groups (2 to <6 years; 6-9 years) were performed using parental-reported data on fruit, vegetables and sugar-sweetened beverages (SSB) consumption, PA performance and television video/DVD viewing.RESULTS:Five clusters were identified. Associations between CVD risk factors and score, and clusters were obtained by multiple linear regression using cluster 5 ('low beverages consumption and low sedentary') as the reference cluster. SBP was positively associated with clusters 1 ('physically active'; β=1.34; 95% confidence interval (CI): 0.02, 2.67), 2 ('sedentary'; β=1.84; 95% CI: 0.57, 3.11), 3 ('physically active and sedentary'; β=1.45; 95% CI: 0.15, 2.75) and 4 ('healthy diet'; β=1.83; 95% CI: 0.50, 3.17) in older boys. A positive association was observed between CVD risk score and clusters 2 (β=0.60; 95% CI: 0.20, 1.01), 3 (β=0.55; 95% CI: 0.14, 0.97) and 4 (β=0.60, 95% CI: 0.18, 1.02) in older boys.CONCLUSIONS:Low television/video/DVD viewing levels and low SSB consumption may result in a healthier CVD profile rather than having a diet rich in fruits and vegetables or being physically active in (pre-)school children.European Journal of Clinical Nutrition advance online publication, 1 May 2013; doi:10.1038/ejcn.2013.84.

Caucasian children's fat mass: routine anthropometry v. air-displacement plethysmography
- 2013

Journal article (peer-reviewed)abstract
- The present paper will use fat mass percentage (FM%) obtained via BOD POD (R) air-displacement plethysmography (FMADP%) to examine the relative validity of (1) anthropometric measurements/indices and (2) of FM% assessed with equations (FMeq%) based on skinfold thickness and bioelectrical impedance (BIA). In 480 Belgian children (aged 5-11 years) weight, height, skinfold thickness (triceps and subscapular), body circumferences (mid-upper arm, waist and hip), foot-to-foot BIA (Tanita (R)) and FMADP% were measured. Anthropometric measurements and calculated indices were compared with FMADP%. Next, published equations were used to calculate FMeq% using impedance (equations of Tanita (R), Tyrrell, Shaefer and Deurenberg) or skinfold thickness (equations of Slaughter, Goran, Dezenberg and Deurenberg). Both indices and equations performed better in girls than in boys. For both sexes, the sum of skinfold thicknesses resulted in the highest correlation with FMADP%, followed by triceps skinfold, arm fat area and subscapular skinfold. In general, comparing FMeq% with FMADP% indicated mostly an age and sex effect, and an increasing underestimation but less dispersion with increasing FM%. The Tanita (R) impedance equation and the Deurenberg skinfold equation performed the best, although none of the used equations were interchangeable with FMADP%. In conclusion, the sum of triceps and subscapular skinfold thickness is recommended as marker of FM% in the absence of specialised technologies. Nevertheless, the higher workload, cost and survey management of an immobile device like the BOD POD (R) remains justified.

Stress, emotional eating behaviour and dietary patterns in children

Journal article (peer-reviewed)abstract
- Psychological stress has been suggested to change dietary pattern towards more unhealthy choices and as such to contribute to overweight. Emotional eating behaviour could be an underlying mediating mechanism. The interrelationship between stress, emotional eating behaviour and dietary patterns has only rarely been examined in young children. Nevertheless, research in children is pivotal as the foundations of dietary habits are established starting from childhood and may track into adulthood. In 437 children (5-12 years) of the ChiBS study, stress was measured by questionnaires on stressful events, emotions (happy, angry, sad, anxious) and problems (emotional, peer, conduct and hyperactivity). Data were collected on children's emotional eating behaviour and also on dietary patterns: frequency of fatty foods, sweet foods, snacks (fat and sweet), fruit and vegetables. Stressful events, negative emotions and problems were positively associated with emotional eating. Positive associations were observed between problems and both sweet and fatty foods consumption. Negative associations were observed between events and fruit and vegetables consumption. Overall, stress was associated with emotional eating and a more unhealthy dietary pattern and could thus contribute to the development of overweight, also in children. Nevertheless, emotional eating behaviour was not observed to mediate the stress-diet relation. (C) 2012 Elsevier Ltd. All rights reserved.

- Abstract ABSTRACT: BACKGROUND: Children are not always recognized as being susceptible to stress, although childhood stressors may originate from multiple events in their everyday surroundings with negative effects on children's health. METHODS: As there is a lack of large-scale, European prevalence data on childhood adversities, this study presents the prevalence of (1) negative life events and (2) familial and social adversities in 4637 European pre- and primary-school children (4--11 years old), using a parentally-reported questionnaire embedded in the IDEFICS project ('Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS'). RESULTS: The following findings were observed: (1) Certain adversities occur only rarely, while others are very regular (i.e. parental divorce); (2) A large percentage of children is shielded from stressors, while a small group of children is exposed to multiple, accumulating adversities; (3) The prevalence of childhood adversity is influenced by geographical location (e.g. north versus south), age group and sex; (4) Childhood adversities are associated and co-occur, resulting in potential cumulative childhood stress. CONCLUSIONS: This study demonstrated the importance of not only studying traumatic events but also of focusing on the early familial and social environment in childhood stress research and indicated the importance of recording or monitoring childhood adversities.

Journal article (peer-reviewed)abstract
- The prevalence of childhood stress and psychosomatic and emotional symptoms (PES) has increased in parallel, indicating that adverse, stressful circumstances and PES in children might be associated. This study describes the prevalence of PES in European children, aged 4-11 years old, and examines the relationship among PES, negative life events (NLE) and familial or social adversities in the child's life. Parent-reported data on childhood adversities and PES was collected for 4,066 children from 8 European countries, who participated in the follow-up survey of IDEFICS (2009-2010), by means of the 'IDEFICS parental questionnaire'. A modified version of the 'Social Readjustment Rating Scale', the 'KINDL Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents' and the 'Strengths and Difficulties Questionnaire' were incorporated in this questionnaire, as well as questions on socio-demographics, family lifestyle and health of the child. Chi-square analyses were performed to investigate the prevalence of PES among survey centres, age groups and sex of the child. Odds ratios were calculated to examine the childhood adversity exposure between PES groups and logistic regression analyses were conducted to investigate: (a) the contribution of the number and (b) the specific types of experienced adversities on the occurrence of PES. 45.7% of the children experienced at least one PES, with low emotional well-being during the last week being most frequently reported (38.2%). No sex differences were shown for the prevalence of PES (P = 0.282), but prevalence proportions rose with increasing age (P < 0.001). Children with PES were more frequently exposed to childhood adversities compared to children without PES (e.g. 13.3 and 3.9% of peer problems and 25.4 and 17.4% of non-traditional family structure in the PES vs. no PES group, respectively, P < 0.001). An increasing number of adversities (regardless of their nature) was found to gradually amplify the risk for PES (OR = 2.85, 95% CI = 1.98-4.12 for a number of a parts per thousand yen3 NLE), indicating the effect of cumulative stress. Finally, a number of specified adversities were identified as apparent risk factors for the occurrence of PES, such as living in a non-traditional family structure (OR = 1.52, 95% CI = 1.30-1.79) or experiencing peer problems (OR = 3.55, 95% CI = 2.73-4.61). Childhood adversities were significantly related to PES prevalence, both quantitatively (i.e. the number of adversities) and qualitatively (i.e. the type of adversity). This study demonstrates the importance and the impact of the child's family and social context on the occurrence of PES in children younger than 12 years old.
