“…The fact that the prevalence of wheeze, allergic rhinitis and atopic eczema symptoms was lower in high-SES school children was opposite to the finding from a previous study conducted in children attending 30 schools in socio-economically diverse areas of Cape Town, South Africa, which reported that the prevalence of asthma, recent wheeze and allergic rhinitis increased from lowest to highest SES [28,29]. One of the possibilities to consider is that certain viral infections, which might be associated with allergy-like symptoms and difficult to differentiate from real allergy by parents, were more prevalent in the low-SES children of the current study [30,31].…”

SummaryBackground In urban centres of developing countries, there is great variation in socioeconomic status (SES) and lifestyle; however, little information is available on allergic disorders in groups with high-or low-SES within the same urban area. Objective To determine the prevalence of allergic disorders and investigate risk factors related to them among high-and low-SES schoolchildren in Makassar, the capital city of South Sulawesi, Indonesia. Method This cross-sectional study was performed in 623 children originating from high-(N = 349) and low-SES (N = 274) schools. Information on reported allergic symptoms and potential factors associated with allergic disorders was obtained by questionnaire. Specific IgE and skin prick test (SPT) reactivity were determined against aeroallergens [Dermatophagoides pteronyssinus (HDM) and cockroach]. Total IgE and helminth infections were also assessed. Result The prevalence of SPT to any aeroallergens was significantly higher in high-SES than in low-SES school (25% vs. 8%, P < 0.001, respectively). However, specific IgE against cockroach and total IgE were significantly lower in high-than in low-SES children. Allergic symptoms were reported more often in low-compared to high-SES children. Specific IgE to aeroallergens significantly increased the risk of SPT positivity to the same aeroallergen in the high-, but not in the low-SES children. In the high-but not in low-SES, there was a significant positive association between SPT to HDM and wheeze. Similarly, cockroach skin reactivity and elevated BMI increased the risk of eczema in the high-SES children only. Conclusion and Clinical Relevance Skin prick test is higher in high-SES, whereas IgE and allergic symptoms are higher in low-SES children. Specific IgE is a risk factor for being SPT-positive, and SPT positivity is a risk factor for allergic symptoms but only in children of high-and not low-SES school. Therefore, the socio-economic status of a child might affect the diagnosis of allergic disease in a developing country.

“…Fuel type used for cooking may be related to socio-economic status (SES). However, unlike atopy that is more common in higher SES groups [29], the influence of SES on asthma prevalence or incidence is conflicting [30][31][32]. Differences in study methodologies may be one of the reasons for these conflicting findings.…”

Background This is the fifth study that applied the International Study of Asthma and Allergies in Childhood (ISAAC) methodology in the Southern African Development Community (SADC region). However, it is the first ISAAC study that focused on 6-to 7-year-old children living in South Africa and that also investigated the association between potential risk factors and asthma symptoms. Objective To assess the 12-month prevalence of wheeze and severe wheeze along with their potential risk factors. Setting Within a 60-km radius from the Polokwane city centre, Limpopo Province. Methods The survey was conducted during August 2004 and February 2005. Parents/guardians of 6-to 7-year-old children completed the questionnaires in English, Afrikaans or North-Sotho. However, the statistical analyses were restricted to the North-Sotho group (n = 2,437). Results The 12-month prevalence rates of wheeze and severe wheeze were 11.2% and 5.7%, respectively. The 12-month prevalence rates of eczema symptoms and rhinoconjunctivitis symptoms were 8.0% and 7.3%, respectively. Living in a rural area significantly decreased the likelihood of wheeze by 31%. Exposure to environmental tobacco smoke at home and the presence of eczema symptoms and rhinoconjunctivitis symptoms increased the likelihood of wheeze by 77%, 104% and 226%, respectively. Only the presence of rhinoconjunctivitis symptoms increased the likelihood of severe wheeze by 107%. Conclusion Wheeze appears to be an emerging public health problem in the Polokwane area. Hopefully, detailed analytical intervention studies will further explicate these results in the near future.

“…First of all a distinction must be made between risk of asthma ever (lifetime risk) and current symptoms [2]. Gross national product per capita is generally associated with both an increasing prevalence of wheezing ever and wheezing in the last 12 months [7].…”

“…This has not generally been the pattern for asthma, where the lifetime prevalence of symptoms is usually higher in more affluent societies [2,3], and a rising prevalence of asthma is a price paid for increasing national prosperity. This trend is probably inevitable since to date, no public health strategy for large-scale primary prevention of asthma has yet proved feasible or effective.…”
