Abstract
The prevalence of allergic diseases has been steadily increasing worldwide to a point where the World Allergy Organization estimates that 30–40% of the world population is now affected by one or more allergic conditions. Allergic Rhinitis (AR) is a common inflammatory disorder affecting the nasal membranes characterized by symptoms such as sneezing and nasal congestion. It is a global health problem; conservative estimates suggest that approximately 500 million people worldwide are affected by the disease. The burden of AR is often under-estimated since the disease is not life-threatening. However, it can cause significant morbidity, through both the physical symptoms and its impact on quality of life and well-being. It has a profound effect on many aspects of daily life such as sleep, work/school, and social life, having been shown to result in fatigue and mood changes, to impair cognitive function, and to lead to depression and anxiety. Data on the prevalence and burden of AR in the Middle East particularly, is scarce. Most studies have been carried out among school children, many of which have been based on the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires and a wide variation in prevalence has been reported. Differences in prevalence have been reported between countries in the region and prevalence has also been shown to vary between the age groups of the children included in the studies. The aim of work of the present study was to estimate the prevalence of allergic rhinitis and risk factors associated with it among school children of Shat Greba primary school in Damietta. ranging from 6 to 15 years, 54.2 % were females and 69.8% had normal weight. In addition, 44% & 31% of their fathers and mothers had university or higher education, respectively, 64.5% of them have crowdness index 2 or more.
