Background: The parallel increase in prevalence of asthma and obesity in childhood has led to an increasing body of evidence about a possible link between the two conditions.

Objective and hypotheses: To assess the prevalence of asthma symptoms in a representative sample of Greek schoolchildren and to evaluate its association with overweight/obesity as well as other socioeconomic, demographic and lifestyle factors.

Method: This is a cross-sectional study conducted from October 2012–December 2013. A pre-selected, representative elementary school cohort (N=11.751, age range 5.9–12.3 years) was derived, using stratification and PPS methodology. Parents responded to questionnaire and the approved Greek version of the ISAAC core questionnaire and students were measured with high sensitivity methods. IOTF cut offs were used to classify the children. Socio-economic status index was calculated (SES index range 0–13) on years of parental education, rented vs owned residence, m2/person, number of vehicles Logistic regression was applied using STATA 11.0.

Results: The prevalence of asthma symptoms was documented in 31% of population. Boys were 1.22 (CI: 1.13–1.33) times more likely to present with asthma symptoms Overweight (odds ratio: 1.13, 95% CI 1.03 TO 1.25) and obesity (odds ratio: 1.27, 95% CI: 1.11–1.46) were related to the presence of asthma symptoms. Moreover, 1 year increase of age increased the odds of asthma symptoms by 9.6% (CI: 0.94–0.98) and an increase of 5 h/week of sedentary activities increased the odds of asthma by 10.7% (CI: 1.01–1.13).

Conclusion: A strong association between presence of asthma symptoms and obesity and sedentary activities was documented irrespectively of socioeconomic and regional (urban vs rural) factors. The findings stress the importance of public health policies towards obesity prevention and enhancement of physical activities in paediatric populations in our country.
