We investigated secular trends of body mass index (BMI) and waist circumference (WC) in Polish schoolchildren examined through a period of almost 50 years. Data on height, weight and WC came from four cross-sectional surveys conducted in Poland between 1966 and 2012, covering 34,005 boys and 34,008 girls. Raw data of BMI and WC were standardized for age classes. Statistical analyses included the Kruskal-Willis test and Pearson Chi-square test. BMI and WC increased during the studied period; however, the growth was higher for WC (increase by 0.56 and 0.44 SD scores for BMI and 1.05 and 0.77 SD scores for WC in boys and girls, respectively). In boys, secular changes in BMI and WC were similar across childhood, early and late adolescence, while in girls they differed, indicating change in the type of adipose tissue distribution to a more central one in late adolescent girls. Conclusion: During 46 years, there was a tendency to a greater increase of the fraction of individuals with central obesity than the overall one. Since abdominal fat deposit is more connected with higher health risks than subcutaneous fat pattern, probably the number of metabolic complications in Polish children and adolescents will intensify in the future.

Central overweight and obesity in Polish schoolchildren aged 7-18 years: secular changes of waist circumference between 1966 and 2012.

Twenty-five scientists met at Aschauhof, Altenhof, Germany, to discuss various aspects of the complex network of modern health screening, focusing on current scientific topics including medical sciences, human biology, and mathematics; on problems in implementing these results at the practical level of physicians, nurses, technicians, and engineers; and the level of administrative and political decisions. Whereas major scientific advancements have been published in the understanding and the bio-statistical evaluation of anthropometric screening parameters such as serial measurements of height and weight for preventive medical check-ups, BMI screening and surveillance in schools, etc., the implementation of these advancements into current health screening concepts, strategies and decision-making is poor. Fear of discrimination, misperception of body image, behavioural responses and political concerns, meanwhile dominate and negatively interfere with the implementation of recent scientific results into public health screening concepts and practices.
