BackgroundDespite the great steadfastness that Syria has achieved in the face of more than a decade of stifling crisis followed by the global COVID-19 pandemic, the heavy impacts of these long rough years are certain and crucial on the health and nutrition levels, specially on vulnerable groups like women and children. Moreover, the lack of research and data on health and nutritional status of children within Syria makes it very difficult to draw conclusions and act effectively. The purpose of the current study was to evaluate growth development and give an insight about the public health awareness and nutritional practices among Syrian primary schools children.MethodsA cross-sectional study was conducted among private and public primary schools’ students aged 6 to 9 years old in Homs governorate in January to April 2021, anthropometric measures were taken and data assessment of socioeconomic background, nutritional practices, and health awareness was achieved by conducting two surveys answered by parents and students.ResultsWe defined the total prevalence of obesity (11.8%), underweight (5.6%) and stunting (13.8%), with a significant increased in underweight and stunting prevalence ,(9%, 21.6%) respectively, among public schools’ students compared to private schools’ students. Differences in nutritional practices and health awareness were recorded between public and private schools’ students under socioeconomic impact.ConclusionsThis study contributes to evaluate the burden of crisis and COVID-19 pandemic on Syrian children growth and health practices in Syria. Improving health awareness and nutritional support among Syrian families to help children meet their growth needs is recommended. Moreover, additional research should be conducted to evaluate micro-nutrients deficiencies and provide appropriate medical support effectively.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12887-023-04115-w.
