Objectives. To estimate the prevalence of current asthma-like symptoms and current allergic diseases among preschool children and to determine the risk factors. Materials and methods. Cross-sectional study included children aged 3-6 years. The study was conducted in 5 towns of Altai region. Prevalence of allergic diseases was assessed using the Russian version of the ISAAC questionnaire. Results. According to questionnaire the prevalence of current asthma-like symptoms was 11,1%, current allergic rhinoconjunctivitis - 7,5%, current atopic dermatitis -12,3%. Out of 3205 children asthma was diagnosed in 0,9%, allergic rhinoconjunctivitis - in 3%, atopic dermatitis - in 7,9%. Family history of allergic diseases increases risk of development of the current asthma-like symptoms twice (OR=2,11; 95% CI=1,66-2,68), current allergic rhinoconjunctivitis by 2,8 times (OR=2,85; 95% CI=2,16-3,75), current atopic dermatitis by 4,6 times (OR=4,62; 95% CI=3,69-5,77). The male sex increases risk of the development of current asthma-like symptoms by 2,6 times (OR=2,63; 95% CI=1,17-5,93), current allergic rhinoconjunctivitis by 1,3 times (OR=1,35; 95% CI=1,03-1,76), smoking of parents on the first year of life of the child increases risk of development of current asthma-like symptoms by 1,6 times (OR=1,61; 95% CI=1,15-2,24), breastfeeding duration less than 6 months increases the risk of development of current atopic dermatitis by 1,6 times (OR=1,62; 95% CI=1,26-2,09; p

Background. Information on atopic dermatitis (AD) epidemiology in preschool children is scarce. Objectives. To estimate the prevalence, clinical, allergological characteristics and risk factors of AD in preschool children. Materials and methods. 5156 children aged 3-6 years old living in the Altai Territory participated in the study. The study included a screening and clinical phases. At the screening stage of the study the prevalence of AD was evaluated using the Russian version of the ISAAC questionnaire, risk factors were evaluated using the additional questionnaire. At the clinical stage diagnosis of AD was verified by allergists. Results. The prevalence of atopic dermatitis was 9,9%. 73,8% of children had mild AD; 58,5% of children were sensitized: 25 (15,6%) to food allergens - 12 (7,2%) to egg, 12 (7,2%) to cow’s milk, 6 (3,6%) to wheat flour and 8 (4,9%) to fish. The most important inhaled allergens were house dust mites, the sensitivity to them was diagnosed in 44 (26,8%) children. The family anamnesis of allergic diseases increases risk of development of AD by 5 times (OR=5,7; 95% CI=4,1-7,9; p

Recurrent Wheeze

BackgroundRelationship between recurrent wheeze and airway function and inflammation in preschool children is not fully known.ObjectiveTo investigate the relationship between recurrent wheeze and airway inflammation, lung function, airway hyper-reactivity (AHR) and atopy in preschool children.DesignObservational study, comparing forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and mid-forced expiratory flow (FEF25%–75%), dose–response slope (DRS), exhaled nitric oxide (eNO) and atopic sensitisation between children with recurrent wheeze and those without.SettingPopulation-based, cross-sectional study in Seoul and the Gyeonggi province of Korea conducted as a government-funded programme to perform standardised measurement of the prevalence of allergic diseases, and related factors, in preschool children.Participants900 children aged 4–6 years.Primary and secondary outcome measureseNO, FEV1/FVC, FEF25%–75%, DRS, atopic sensitisation and allergic diseases.MethodsChildren completed the modified International Study of Asthma and Allergies in Childhood questionnaire and underwent eNO assessments, spirometry, methacholine bronchial provocation tests and skin prick tests. Recurrent wheeze was defined as having a lifetime wheeze of more than three episodes, based on the questionnaire. The frequency of hospitalisation and emergency room visits was also obtained by means of the questionnaire. ‘Current’ wheeze was defined as having symptoms or treatments within the past 12 months.ResultsThe prevalence of recurrent wheeze was 13.4%. Children with recurrent wheeze showed a higher prevalence of lifetime or current allergic rhinitis (p=0.01 and p=0.002, respectively) and lifetime atopic dermatitis (p=0.007). Children with recurrent wheeze showed lower FEV1/FVC (p=0.033) and FEF25%–75%(p=0.004), and higher eNO levels (p=0.013) than those without recurrent wheeze. However, the DRS, prevalence of atopic sensitisation and serum IgE levels were not significantly different between the two groups.ConclusionsRecurrent wheeze in preschool children may be associated with airway inflammation and diminished airway function, but not with AHR or atopy.

BackgroundIn 2003, the International Study of Asthma and Allergies in Childhood (ISAAC) estimated the prevalence of asthma, rhinitis and eczema symptoms in Quito, Ecuador. Since then, no update of this study has been done in the last years. This study examined changes in the prevalence of asthma–rhinitis–eczema symptoms over a 16 years period in Quito and explored possible risk factors.MethodsWe conducted a comparative cross-sectional study in an adolescent population following the Global Asthma Network (GAN) methodology. A written questionnaire was used to explore symptoms of asthma–rhinitis–eczema. We calculated the prevalence and 95% CIs for each of the symptoms and compared them with the ISAAC results. We conducted bivariate and multivariate analysis using logistic regression to identify possible risk factors for recent wheeze, rhinitis and eczema.ResultsA total of 2380 adolescents aged between 13 and 14 years were evaluated. The prevalence of doctor diagnosis for asthma, rhinitis and eczema was 3.4%, 8.5% and 2.2%, respectively. Compared with ISAAC results, we found a lower prevalence of wheeze and eczema symptoms: wheeze ever (37.6% vs 12.7%), recent wheeze (17.8% vs 6.5%), asthma ever (6.9% vs 4.6%), recent rush (22.4% vs 13.9%) and eczema ever (11.7% vs 3.6%). The prevalence of rhinitis symptoms in the GAN study was higher than the ISAAC results: nose symptoms in the past 12 months (36.6% vs 45.8%) and nose and eye symptoms in the past 12 months (23.1% vs 27.9). Significant associations were observed between symptoms of asthma–rhinitis–eczema and sex, race/ethnicity, smoking habit, physical exercise and sedentary activities.ConclusionsIn the last two decades, the prevalence of asthma and eczema symptoms in adolescent population in the city of Quito has significantly declined; however, the prevalence of rhinitis symptoms has increased. The reduction in asthma symptoms could be related to better managing the disease and changes in local environmental risk factors in the last years. Further studies must be conducted in the country to evaluate the change in trends in asthma and other related allergic diseases.

Active Trachoma

Abstract Background፡ Trachoma is a neglected eye problem and primary cause of preventable corneal blindness. In endemic areas, initial infection occurs in early childhood, and recurrent infection progress to scarring and blindness. In the past four decades, GET2020 initiative eliminated Trachoma from developed countries through enhancements of hygiene and sanitation but still a problem of developing countries. Studies and reports also indicated the presence of high prevalence of Trachoma in Ethiopia and in the study area. Thus, the purpose of this study is to assess the prevalence and risk factors of active trachoma among rural preschool children in Wadla district, Ethiopia. Methods: A community based cross-sectional study design was considered to gather data from 583 children using sample size determination, but 596 children were screened for signs of active trachoma because of the sampling procedure nature, cluster sampling technique. Wadla district has 150 rural villages, which are similar in topography and socio-demographic status. Based on rule of thumb 30 villages (clusters) were included for the data collection. An interview on socio-demographic data were collected by health informatics professionals using structured interview questioners, which were prepared through reviewing previous literatures and pretested in Meket Woreda. Eye examination was performed by Integrated Eye Care Workers who trained for one month for the purpose of trachoma screening by Carter center-Ethiopia. Results - The prevalence of active trachoma among rural pre-school children in Wadla district was 130 (21.8%). Regarding risk factors, poor economic status (AOR (95% CI), (3.8 (1.3-11.4), being 37- 48 months old (AOR (95% CI), (4.2 (1.5-12.0), thatched house roof (AOR (95%CI), (4.4 (1.4-13.6), presence of fly in nearby home (AOR (95% CI), 4.6 (2.1-9.9), once weekly face washing frequency (AOR (95% CI), 8.6 (2.5-29.3), unwashed face for longer than a week (AOR (95% CI), 10.6 (2.9-37.7), not using soap (AOR (95% CI), 4.5 (1.8-11.3), and absence of latrine (AOR (95% CI), 5.1 (2.0-12.9) have association with active trachoma. Conclusion: Environmental factors weigh other factors and this could capture the intention of policy makers to emphasize on the environmental components like sanitation including face cleanness to decrease the prevalence of trachoma

Abstract Background Our objective was the validation of a scale to assess the hygiene hypothesis and the link between hygiene, and asthma among 3 to 5 years old Lebanese children in preschool.Methods Between November 2018 and March 2019, this cross-sectional study was carried out, enrolled 515 preschool children’ asthma and potential risk factors, including hygiene, were assessed using a standardized questionnaire. A specific hygiene hypothesis related scale was generated and validated for this purpose.Results Items related to the hygiene hypothesis scale have led to a convergence over a nine factors solution, having over than 1 Eigenvalue, which explains the variance total of 65.86%. Cronbach’s alpha values corresponding to the hygiene hypothesis related scale (0.696) was deemed acceptable. The backward logistic regression, taking as dependent variable the asthma’s presence or absence in child, showed that living in prairie (ORa=2.42), playing outside (ORa=2.80), having respiratory problems (ORa=4.18), attending a kindergarten (ORa=2.76), and having a sister with seasonal allergy (ORa=6.86) had significant association with increased odds of occurrence of children’s asthma. The hygiene hypothesis related score was not found to be associated with increased asthma odds (p=0.663).Conclusion Current findings suggested that home cleaning and personal cleanliness were not correlated with asthma in preschool children. Future studies will require more in-depth analyses of microbial exposure, allowing proper identification of unequivocal species and functional characteristics.

Abstract Background Intestinal parasitic infestations triggered considerable gastrointestinal morbidity, malnutrition, and mortality worldwide. In particular, young children in developing countries affected most. Helminthiasis infestation accounts for 10–20% of prevalence on preschool children worldwide. Unfortunately, small children below 5 years are uniquely susceptible to intestinal parasitic infestations in poor communities. This is because of children’s behavior like playing with soil and putting hand -to- mouth habit. Thus, the aim of this study was to assess the prevalence and risk factors of intestinal parasitic infestations among preschool children in Sekota town, Ethiopia. Methods A community-based cross-sectional study was carried out on 378 preschool children in Sekota town from February 15 – March 10/2019. Stool specimens were collected and examined for intestinal parasites using wet mount and formal ether concentration technique. The risk factors of intestinal parasites were assessed using a pretested structured questionnaire. The data were entered and analyzed using Epi-data version 4.2.0.0 and SPSS-version 23 statistical software respectively. Both bivariable and multivariable analysis was carried out, and potential co-linearity was tested for closely similar variables. Variables with P value less than 0.05 in multivariable analysis was considered as statistically significant and reported with 95% CI and odds ratio. Results The prevalence of intestinal parasitic infestations in Sekota town on wet mount and formal ether concentration techniques was 83(21.9%), (95% CI, 17.7–26.3%) and 113(29.9%), (95% CI, 25.1–34.8%) respectively. In multivariable analysis, not taking medication as periodical deworming (AOR, 95% CI), (2.5, 1.5–4.3), presence of animals in the living room (AOR, 95% CI) (3.1, 1.8–5.3), and being a government employee as an occupation (AOR, 95% CI), (3.4, 1.1–10.0) were increasing the odds of intestinal parasitic infestations. Conclusions The prevalence of intestinal parasitic infestations in Sekota town is high, which is a public health problem. The risk factors that contributed to intestinal parasitic infestations in this study were preventable and modifiable. Therefore, the concerned bodies need to emphasis on periodical deworming and keeping animals in separate room.
