Prevalence and potential risk factors of rhinitis and atopic eczema among schoolchildren in Vientiane capital, Lao PDR: ISAAC questionnaire.
In 1998, an epidemiological study on asthma and allergic diseases using ISAAC questionnaire in Laos was first conducted in the recommended schools located in Vientiane capital showing that the prevalence of rhinoconjunctivitis and atopic eczema were 23.7% and 7.1% among children aged 13-14 year-old, respectively. This study aimed to reassess the prevalence of rhinoconjunctivitis and atopic eczema using the same ISAAC questionnaire by employing random sampling method and to identify the potential risk factors for these rhinitis and atopic eczema. This school-based cross-sectional study was conducted in Vientiane capital from December 2006 to February 2007. Of 536 children, prevalence of rhinoconjunctivitis and atopic eczema among schoolchildren were 9.3% and 11.8%, respectively. Children with early respiratory infection (AOR = 4.06; p = 0.001), parasitic infestation especially by Opisthorchis viverrini (AOR = 3.41; p < 0.05) were more likely to have rhinitis. While history of measles (OR = 2.24; p < 0.01) and respiratory infection (OR = 1.96; p < 0.05), eating vegetables everyday (AOR = 2.96; p < 0.01) were associated with atopic eczema. The similarity of prevalence of rhinitis and rhinoconjunctivitis were also revealed between children aged 13-14 year-old in this study and 6-7 in the previous study in 1998. The validation study on ISAAC questionnaire in Lao language is needed in order to generalize this questionnaire in Lao.
