Methodology and implementation of the WHO European Childhood Obesity Surveillance Initiative (COSI).

Establishment of the WHO European Childhood Obesity Surveillance Initiative (COSI) has resulted in a surveillance system which provides regular, reliable, timely, and accurate data on children's weight status-through standardized measurement of bodyweight and height-in the WHO European Region. Additional data on dietary intake, physical activity, sedentary behavior, family background, and school environments are collected in several countries. In total, 45 countries in the European Region have participated in COSI. The first five data collection rounds, between 2007 and 2021, yielded measured anthropometric data on over 1.3 million children. In COSI, data are collected according to a common protocol, using standardized instruments and procedures. The systematic collection and analysis of these data enables intercountry comparisons and reveals differences in the prevalence of childhood thinness, overweight, normal weight, and obesity between and within populations. Furthermore, it facilitates investigation of the relationship between overweight, obesity, and potential risk or protective factors and improves the understanding of the development of overweight and obesity in European primary-school children in order to support appropriate and effective policy responses.

Evidence-based policy making for health promotion to reduce the burden of non-communicable diseases in Moldova.

The Republic of Moldova faces several concurrent health challenges most notably an increase in chronic non-communicable diseases, spiralling health care costs and widening health inequalities. To accelerate progress in their resolution there is a need for new and innovative health promotion and behaviour change communication interventions. The Ministry of Health, Labour and Social Protection in collaboration with the newly created National Agency for Public Health held a conference on the occasion of the Moldovan National Day of Health Promotion on 14th March 2018 in which national and invited international experts exchanged their views on (1) best practice examples of behaviour change interventions, health promotion activities and lessons learned from the UK and elsewhere; and (2) possible ways forward for Moldova to implement cost-effective and evidence-based intersectoral health promotion programmes. The experts provided recommendations on implementing behaviour change interventions to reduce and prevent obesity; on the creation of a favourable tobacco control environment to reduce smoking prevalence; and on how physical activity programme design can benefit from health psychology research. All these strategies could foster health promotion activities and ultimately contribute to improving the health outcomes of the Moldovan population.
