The Dietary Habits of Non-asthmatic Schoolchildren in Lhasa, Tibet

Abstract

The occurrence of asthma symptoms and food consumption frequencies in 13- to 14-year-old schoolchildren was investigated in Lhasa, Tibet (3,658 meters above sea level). A total of 99.2% of the schoolchildren reported that they had not experienced any wheezing during the prior 12 months. Among these students, more than 50% had consumed rice, meat, fruits, and vegetables at least three times per week in the preceding year. More than 70% of the non-asthmatic students rarely consumed margarine; 50% of these students rarely ate fast food; and 40% only occasionally ate fish during the prior 12 months. The dietary habits of the schoolchildren in Lhasa may have some potential beneficial roles in contributing to the low prevalence of asthma in this high altitude region.
