Prevalence of Overweight and Obesity in 6–7-Year-Old Children—A Result of 9-Year Analysis of Big City Population in Poland

摘要

Excess body weight is a serious public health problem, which affects both adults and children. Unfortunately, the prevalence of excess body weight in children in Poland is not subject to any regular screening. The aim of this study was to analyze the prevalence of overweight and obesity in 6–7-year-old children in the municipality of Gdańsk in the years 2008–2016. The anthropometric parameters of 12,330 children (49.55% girls and 50.45% boys) with a mean age of 6.53 ± 0.38 years were analyzed. The prevalence of overweight was 7.49% (7.91% girls and 7.07% boys) and obesity 4.24% (4.47% girls and 3.99% of boys). There was no difference in the prevalence of neither overweight nor obesity between boys and girls ( = 0.076). However, the prevalence of overweight and obesity combined is higher in girls (12.38% vs. 11.06%, = 0.023). There were no statistically significant differences in the prevalence of overweight and obesity neither in the group of girls nor in the group of boys in children aged 6–7 years in yearly cohorts examined between 2008 and 2016. The prevalence of excess body weight in this population is at a stable level.
