Background

Many studies demonstrated the existence of geographic differences, within and between countries, in the prevalence of asthma, rhinitis, and eczema. However, in Palestine, there are no comprehensive Palestinian data to compare with those from other regional and international centers.

Objective

To describe the prevalence of asthma and asthma symptoms in schoolchildren in two districts (Ramallah and North Gaza) in Palestine.

Methods

After a two-stage stratified systematic sampling, approximately 14,500 schoolchildren, from the first and second grades of elementary school (ages 5 to 8 years) and eighth and ninth school grades (ages 12 to 15 years), were invited to participate in a survey using International Study of Asthma and Allergies in Childhood phase III questionnaires and protocols.

Results

In general, younger children were reported to have a higher 12-month wheezing prevalence rate than older children (9.6 and 7.2%, respectively), and more physician-diagnosed asthma (8.4 and 5.9%, respectively). However, nocturnal cough and exercise-related wheezing were higher in the older age group compared with younger children. Younger children living in North Gaza district showed slightly higher prevalence rates for asthma and asthma symptoms, but older children had higher rates in Ramallah district. After adjustment using logistic regression analysis, male sex, living in inland areas, and younger age were shown to predict 12-month wheezing and physician-diagnosed asthma.

Conclusions

Palestinian children have asthma symptoms rates that are similar to several countries in the Mediterranean region such as Spain and Turkey, but still lower than other Middle East countries such as Saudi Arabia and Israel.

      In Spain, considerable geographic variation in the prevalence of asthma symptoms was noted among the 23 centres, emphasising that even among young children, asthma symptoms were more frequent in northern Atlantic cities than in Southern.2 Within Palestinian refugee camps, the prevalence of wheezing in the last 12 months and physician-diagnosed asthma for older schoolchildren was higher in the westernised district of Ramallah than in North Gaza.3 The analysis of three large samples in United Kingdom showed a considerable variation in the prevalence of persistent wheeze and other respiratory symptoms, except occasional wheeze and asthma, by various factors and geographical area.4

      Citation Excerpt :

      Asthma is one of the most common chronic conditions of childhood. Studies 1-7 have documented variations in the rates of asthma and respiratory symptoms within and between countries. In the United States, racial and ethnic differences in the prevalence of asthma and asthma-related symptoms have been demonstrated in several studies, 2,8-10 with lower rates of asthma reported in Mexican Americans.
