Ansätze zur verhältnisorientierten Adipositasprävention bei Kindern und Jugendlichen

[Criteria catalogue to systematize conceptual approaches in universal prevention of childhood overweight : Methodological approach and first results]

BACKGROUND

Overweight and obesity are serious health risks for children and adolescents. Hence, various prevention projects have been initiated and implemented. Until now, a systematic overview of interventions in different settings has been lacking.

AIM(S)/RESEARCH QUESTION

The aim of the "Prevention of child overweight" project (SkAP-project) is to prepare a systematic overview of the conceptual approaches used in universal prevention of overweight among children and adolescents. First of all, a comprehensive criteria catalogue will be developed based on systematic searches. In the next step the criteria catalogue will be applied to identify and characterize conceptual approaches.

DATA AND METHODS

Criteria to describe conceptual approaches as well as determinants of childhood overweight were determined by systematic searches. The searches included relevant data bases and were further expanded by internet and hand search. Three settings (kindergarten, school and communities) and families are addressed by the systematic searches. Additional non-setting specific searches were conducted.

RESULTS

A comprehensive criteria catalogue was developed, which allows a detailed analysis of conceptual approaches. This catalogue covers further quality criteria as well as determinants of childhood overweight.

DISCUSSION

Currently, the criteria catalogue is being employed. Although the detailed analysis of conceptual approaches can be regarded as advantage of the criteria catalogue, there are also some limitations, such as the lack of necessary information provided in publications. Overall, the application will reveal an overview regarding universal prevention in childhood overweight, which is still lacking, and will support development in this field.

Do attitudes, intentions and actions of school food coordinators regarding public organic food procurement policy improve the eating environment at school? Results from the iPOPY study

OBJECTIVE

The present study investigates whether public organic food procurement policies have the potential to induce changes in the school food service environment.

DESIGN

A comparative cross-national survey was conducted in public primary and/or secondary schools in Finland, Germany and Italy. The school food coordinators completed a web-based questionnaire on their attitudes, intentions and actions towards organic school food provision.

SETTING

In Germany, 122 out of 2050 schools in the state of Hesse responded. In Finland, 250 out of 998 schools across the country responded. In Italy, 215 out of 940 schools from eight provinces responded.

SUBJECTS

School food coordinators in the sample of schools in the three countries.

RESULTS

The German and Finnish school food coordinators separately most agreed with the promotion of healthy eating habits (P < 0·001) and organic food (P < 0·001) by schools. The Finnish schools were most likely to adopt a food and nutrition policy (P < 0·001), a health-promoting school policy according to WHO principles (P < 0·001), to have a playground (P < 0·001), to involve physical activity themes in teaching (P = 0·012) and to have a canteen (P < 0·001). The Italian schools were most likely to involve the food and nutrition policy in pedagogical activities (P = 0·004), to serve nutritional school meals (P < 0·001) and to recommend children to eat healthily (P < 0·001). In the three countries, the non-organic schools were less likely to adopt a food and nutrition policy (P < 0·001), a WHO health-promoting policy (P < 0·001) and have a canteen (P = 0·017) than the organic schools.

CONCLUSIONS

The study suggests that there is a gap in the effects of public organic food procurement policy on building a healthier school food environment.
