- 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.

- To assess whether smiley stamps work as a motivational incentive to promote fruit and vegetable eating among children, we conducted a field experiment in ten primary schools in five European countries using one control and one treatment school per country. The six-week experiment was split into three two-week phases before, during and after the smiley was implemented. During the smiley phase, the children received a smiley stamp for choosing a portion of fruits or vegetables. We find an increase attributed to the smiley stamp on children's fruit and vegetable choice and consumption, but also waste. Comparing the effects across countries, we observe significant variations in the smiley effect. This study thus demonstrates, in general, that a low-cost, easy-to-implement incentive such as a smiley stamp has the potential to motivate school children to increase their fruit and vegetable consumption; the study simultaneously underscores the high relevance of context for the effects of incentives.

Sustainable investment : Consequences for psychological well-being
- 2021

Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 13:16

Tidskriftsartikel (refereegranskat)abstract
- This paper sets the stage for research on sustainable investment (SI) related to psychological well-being (PWB). It recognizes the threat of current global consumption levels to exceed the planetary boundaries and asks what roles financial markets may play in reducing these threats without compromising PWB. SI integrates environmental (E), social (S), and governance (G) factors alongside financial factors in investments in company shares and bonds as well as through active engagement in companies. Barriers to ESG integration include lower short-term financial performance, higher financial risks, and insufficient ESG screening by investors. A brief review of PWB shows that reliable and valid measurement methods have been developed, that the resulting measures complement economic and social national welfare indicators, and that health, sufficient material welfare, income equality, and non-material consumption are important determinants of PWB. The challenge is to globally reduce private material consumption levels in affluent countries. It is suggested that one role SI may play is in investing or actively engaging in companies that efficiently meet an increasing consumer demand of non-material consumption. Future research should address this role of SI.

- One purpose of 'identification and prevention of dietary- and lifestyle-induced health effects in children and infants' (IDEFICS) is to implement a standardized community-based multi-component healthy eating intervention for younger children in eight different countries. The present study describes important influencing factors for dietary behaviors among children aged 2-8 years old in order to determine the best approaches for developing the dietary components of the standardized intervention. Twenty focus groups with children (74 boys, 81 girls) and 36 focus groups with 189 parents (28 men, 161 women) were conducted. Only in two countries, children mentioned receiving nutrition education at school. Rules at home and at school ranged from not allowing the consumption of unhealthy products to allowing everything. The same diversity was found for availability of (un)healthy products at home and school. Parents mentioned personal (lack of time, financial constraints, preferences), socio-environmental (family, peer influences), institutional (school policies) and physical-environmental (availability of unhealthy products, price, season) barriers for healthy eating. This focus group research provided valuable information to guide the first phase in the IDEFICS intervention development. There was a large variability in findings within countries. Interventions should be tailored at the personal and environmental level to increase the likelihood of behavioral change.

- BACKGROUND: The current study aimed at describing influencing factors for physical activity among young children to determine the best approaches for developing the IDEFICS community based intervention. METHODS: In 8 European sites a trained moderator conducted a minimum of 4 focus groups using standardized questioning guides. A total of 56 focus groups were conducted including 36 focus groups with parents and 20 focus groups with children, of which 74 were boys and 81 girls. Key findings were identified through independent reviews of focus group summary reports using content analysis methods. FINDINGS: Findings were generally consistent across countries. The greatest emphasis was on environmental physical (eg, seasonal influences, availability of facilities and safety), institutional (eg, length of breaks at school), and social factors (eg, role modeling of parents). Most cited personal factors by parents were age, social economical status, and perceived barriers. Both children and parents mentioned the importance of children's preferences. CONCLUSIONS: To increase physical activity levels of young children the intervention should aim at creating an environment (physical, institutional, social) supportive of physical activity. On the other hand strategies should take into account personal factors like age and social economical status and should consider personal barriers too.

- A detailed banded ideogram representation of the rat chromosomes was constructed based on actual G-banded prometaphase chromosomes. The approach yielded 535 individual bands, a significant increase compared to previously presented ideograms. The new ideogram was adapted to the existing band nomenclature. The gene locus positions in the rat draft DNA sequence were compared to the chromosomal positions as determined by dual-color FISH, using rat (RNO) chromosomes 6 and 15 and a segment of RNO4 as sample regions. It was found that there was generally an excellent correlation in the chromosome regions tested between the relative gene position in the DNA molecules and the sub-chromosomal localization by FISH and subsequent information transfer on ideograms from measurements of chromosomal images. However, in the metacentric chromosome (RNO15), the correlation was much better in the short arm than in the long arm, suggesting that the centromeric region may distort the linear relationship between the chromosomal image and the corresponding DNA molecule.

- © 2016 The Author(s).Background: Making forecasts about biodiversity and giving support to policy relies increasingly on large collections of data held electronically, and on substantial computational capability and capacity to analyse, model, simulate and predict using such data. However, the physically distributed nature of data resources and of expertise in advanced analytical tools creates many challenges for the modern scientist. Across the wider biological sciences, presenting such capabilities on the Internet (as "Web services") and using scientific workflow systems to compose them for particular tasks is a practical way to carry out robust "in silico" science. However, use of this approach in biodiversity science and ecology has thus far been quite limited. Results: BioVeL is a virtual laboratory for data analysis and modelling in biodiversity science and ecology, freely accessible via the Internet. BioVeL includes functions for accessing and analysing data through curated Web services; for performing complex in silico analysis through exposure of R programs, workflows, and batch processing functions; for on-line collaboration through sharing of workflows and workflow runs; for experiment documentation through reproducibility and repeatability; and for computational support via seamless connections to supporting computing infrastructures. We developed and improved more than 60 Web services with significant potential in many different kinds of data analysis and modelling tasks. We composed reusable workflows using these Web services, also incorporating R programs. Deploying these tools into an easy-to-use and accessible 'virtual laboratory', free via the Internet, we applied the workflows in several diverse case studies. We opened the virtual laboratory for public use and through a programme of external engagement we actively encouraged scientists and third party application and tool developers to try out the services and contribute to the activity. Conclusions: Our work shows we can deliver an operational, scalable and flexible Internet-based virtual laboratory to meet new demands for data processing and analysis in biodiversity science and ecology. In particular, we have successfully integrated existing and popular tools and practices from different scientific disciplines to be used in biodiversity and ecological research.

- Background: Evidence for the effect of dietary energy on BMI z-scores in young children is limited. We aim to investigate cross-sectional and longitudinal effects of daily energy intake (EI) on BMI z-scores of European boys and girls considering growth-related height dependencies of EI using residual EI. Methods: To investigate cross-sectional and longitudinal effects of daily energy intake (EI) on BMI z-scores of European boys and girls considering growth-related height dependencies of EI using residual EI. Methods: Subjects were children aged 2-< 10 y old (N = 2753, 48.2 % girls) participating in the IDEFICS (Identification and prevention of Dietary-and lifestyle-induced health EFfects In Children and infantS) baseline and follow-up examination. Usual EI (kcal/day) was calculated based on the National Cancer Institute-method excluding subjects with implausible reported EI. Effect of age, height and sex-adjusted residuals of EI on BMI z-score was investigated stratified by baseline age-group (2-< 4 y, 4-< 6 y, 6-< 8 y and 8-< 10 y) cross-sectionally using linear regression models adjusted for relevant confounders (crude model: age, sex, country; fully adjusted model: plus parental ISCED level, parental BMI, screen time; subgroup analysis: plus objectively measured physical activity). Longitudinal associations were estimated between changes in (Delta) residual EI per year and Delta BMI z-score per year with adjustments analogously to the cross-sectional models but with additional adjustment for residual EI at baseline. Results: Cross-sectionally, positive associations were observed between residual EI and BMI z-score for the full study sample, for boys and in older (>= 6 years) but not in younger children in the crude and fully adjusted model. Longitudinally, small positive associations were observed between Delta residual EI per y on Delta BMI z-score per y for the full study sample and in 4-< 6 y olds in the crude and fully adjusted model. Conclusion: In conclusion, EI above the average intakes for a certain sex, age and height are weakly associated with BMI z-scores in European children. Residual EI may be considered as a useful exposure measure in children as it accounts for growth-related changes in usual EI during childhood.
