Abstract

Objective Obesity in childhood and adolescence period, is one of the most serious public health problems with it’s remarkable increased prevalence and it is correlated with the increased adult morbidity and mortality due to its causing noncommunicable diseases such as diabetes and hypertension. This study aims to identify the secular trend by performing meta-analysis of childhood and adolescent obesity prevalence studies conducted in different regions of our country since 1990 to 2015. Methods Uludag University Library Database was searched for relevant articles published prior to March 2017. The heterogeneity of the studies in the meta-analysis was tested by the I2 statistic and Cochran’s Q test and the obesity trend analyses were examined by chi-square trend analysis with respect to the 5 years periods. The statistical significance level was taken as α=0.05. Results After screening 76 papers for obesity we included 58 papers for obesity. The prevalence of obesity increased from 0.6% to 7.3% and obesity increased 11.6-fold from 1990-1995 to 2011-2015. The prevalence of obesity increased in both gender, but boys were more likely to be obese than girls. Conclusion Studies on obesity prevalence in 5-19 age group in Turkey have gained importance especially in the 2000s. In literature, although remarkable number of prevalence studies, mostly regional, have been conducted in our country in between 2005-2011, a gradual decline was observed afterwards. Not only to regain the importance of regional prevalence studies, but also further national, regular population-based surveys representing Turkey on the prevalence of obesity in children and adolescents are definitely needed.
