Summary

Objectives

To estimate the prevalence of overweight and obesity in 2010 and examine prevalence trends between 2000 and 2010 among school-aged children and adolescents in Cyprus.

Methods

A representative cross-sectional study was undertaken in 2010. Anthropometric data were taken using standard methods from 3090 children. The IOTF cut-offs were used to define overweight and obese participants, and prevalence was compared with a previous representative study performed in 2000. Prevalences with 95% confidence intervals (95% CI) were calculated and logistic regression models were used to estimate 10-year trends.

Results

The overall prevalence of obesity was higher in 2010 (8.1% [95%CI: 7.1, 9.1]) compared to 2000 (5.9% [95%CI: 5.0, 6.8]), p = 0.002. The overall prevalence of overweight was also higher in 2010 (20.1% [95%CI: 18.7, 21.5]) compared to 2000 (16.5% [95%CI: 15.0, 18.0]), p < 0.001. The prevalence of obesity increased at a greater rate in school-aged boys (p = 0.017), and in rural areas (p = 0.001). In rural areas, high maternal education background is associated with a decreased odds for obesity; odds ratio 0.35 (95% CI: 0.17, 0.69), p = 0.003.

Conclusions

The prevalence of obesity and overweight in children and adolescents in Cyprus has increased substantially over a decade, mainly in rural areas and in school-aged boys.

Introduction

Obesity has been one of the most challenging public health issues in the past decades affecting not only developed countries [1], [2] but also developing ones [2], [3] who suffer from the double burden of disease linked to both under- and over-nutrition. The prevalence of obesity among children and adolescents has been increasing during the past decades though there have been reports for a leveling off trend in some developed regions [4], [5], [6], [7], [8].

Cyprus is a European Union member state in the eastern Mediterranean Sea. The prevalence of obesity in Cyprus has been estimated in a representative sample of school-aged children and adolescents for the first time in 2000 [9] and in preschool-aged children in 2004 [10]. In particular, the prevalence of obesity was relatively low in 2–5 year olds being 3% [10] but was much higher in school-aged children reaching 10% at the age of 10–11 y and then decreased to around 4% by the age of 15–17 y [9]. Those results ranked Cyprus among the European countries with the highest prevalences of obesity and overweight at that time [11]. Moreover, there has been evidence that the prevalence of obesity among school-aged children increased substantially within a period of 6 years [12].

Monitoring obesity prevalence is a crucial step in defining national needs and priorities, and evaluating progress of undertaken efforts against obesity. The aim of the present study was to report the 10-year change in the prevalence of overweight and obesity in school-aged children and adolescents in Cyprus.

Methods

A school based study was performed between October 2009 and May 2010 in order to collect anthropometric data to estimate the prevalence of overweight and obesity in a representative sample of school-aged children and adolescents in Cyprus, and compare this prevalence with similar data collected by our Institute 10 years earlier [9]. The survey took place in elementary and secondary schools all over the freely-accessible areas of Cyprus, but in contrary to the previous study [9], not only public

Results

The main characteristics of participants both for the 2009–10 and for the 1999–00 samples are presented in Table 1. There were 3090 participants included in the final analysis of the 2009–10 study (participation rate 65%) whereas, 2467 were included in the earlier study (participation rate 95%). As it is shown in Table 1, the proportion of boys in the 2009–10 study (45.9%) was lower compared to the earlier study (49.1%), p = 0.018. On the contrary there were similar distributions in terms of area

Discussion

Using nationally representative data, the 10 y trends in prevalence of obesity and overweight in children (6.0–11.9 y) and adolescents (12.0–17.9 y) in Cyprus were examined. The present results show that there has been a marked increase in the prevalence of obesity between 1999–00 and 2009–10 time points in children and adolescents 6–17 years of age. The increase was more pronounced in children and adolescents residing in rural areas, and in fact the prevalence of obesity is now higher in rural
