“…These results are consistent with the observation that positive SPT, especially for HDM, are more prevalent in young boys than in girls [16]. A change to female predominance is seen in adolescence [17,18], and this was also seen in our study. In contrast with previous reports [19], we found a significantly higher prevalence of overall SPT positivity in men.…”

Background: Allergic rhinitis (AR) is the most common allergic disorder and its prevalence has significantly increased worldwide, nowadays affecting up to 40% of the population in young adults. The objective of the present survey was to evaluate the prevalence of allergic sensitization and the prevalence of clinically diagnosed AR in a sample of the Belgian population, and to estimate the effect of age and gender. Methods: We performed a cross-sectional population-based study at an annual public fair in Ghent. Participants underwent a skin prick test (SPT) to 3 aeroallergens: a mix of trees (hazel, alder, and birch), grass pollen, and house dust mite (HDM). The clinical relevance of sensitization was assessed by relating relevant symptoms of AR to the corresponding SPT. Results: A total of 2,320 participants (1,475 females, median age 44.7 years, range 3–86) were included in this study. The standardized prevalence rates of sensitization were 13.2% for tree mix, 25.9% for grass pollen, and 25.9% for HDM. Sensitization to at least one of the allergens was present in 40.3% of the subjects. Symptomatic sensitization related to trees was reported in 9.7% of cases, grass-related AR was 17.6%, and HDM-related AR was 17.1%. The overall prevalence of AR was 30.9%. Conclusion: In this study we demonstrated a 40.3% prevalence of a positive SPT to one or more common aeroallergens. A clinical diagnosis of AR was present in 30.9% of cases, peaking in the third and fourth decades of life. It is to be expected that in the next decades, when this generation grows older, the general AR prevalence will further increase.

“…Matheson et al showed that in subjects who were atopic in adult life, the incidence of rhinitis was higher in boys, but this higher incidence reversed in adult life when women had a higher risk than men; and in subjects without atopy in adult life, females had a consistently increased risk of rhinitis compared with males throughout life [5]. Hormonal factors are a possible explanation for these sex differences [5,41]. The higher risk of sinus problems in females in this study is consistent with the previous studies, because we investigated the incidence of every sinus problem in adult population.…”

Prevalence and Determinants of Sinus Problems in Farm and Non-Farm Populations of Rural Saskatchewan, Canada

Although sinus problems have long been recognized as the most common respiratory symptoms associated with agricultural work, there is a scarcity of recent studies and/or reliable estimates as to the true prevalence or risk factors of sinus problems related to farming. The aim of this study was to determine the prevalence of sinus problems in farming and non-farming rural populations and further investigate the association of individual (for example life-style, occupational), contextual (e.g., environmental), and important covariates (e.g., age, sex) with sinus problems. A large-scale cross-sectional study was conducted in farm and non-farm residents of rural Saskatchewan, Canada. A logistic regression model based on a generalized estimating equations approach were fitted to investigate the risk factors of sinus problems. Sinus problems were reported by 2755 (34.0%) of the 8101 subjects. Farm residents were more likely to spend their first year of life on farm compared with non-farm residents, and indicated a significantly lower risk of sinus problems. Meanwhile, occupational exposure to solvent and mold were associated with an increased risk of sinus problems. Some health conditions such as allergy and stomach acidity/reflux, family history, and female sex were also related to a higher risk of sinus problems. Farm residents had a significantly lower risk of sinus problems than non-farm residents, likely due to the exposure to farm specific environments in their early life.

“…Association of personal and environmental factors with the prevalence of sensitization and allergic symptoms Age and gender [15] Overall sensitization to at least one allergen increased signifi cantly with age from 15.9% (95%CI: 12.4-20.0%) for the younger age group up to 30.5% (95%CI: 26.2-35.0%) for the older age group (Fig. A).…”

“…Sensitization to Blatella germanica was present in only 11 (0.5%) children. [15,18] The AAS prevalence rates of eczema, respiratory symptoms and rhinoconjunctivitis for the whole study population are shown in Table 2. In our study, all investigated current allergic symptoms were positively associated with sensitization.…”
