Background: Allergic diseases pose a health problem worldwide. Pollen are widespread aeroallergens which can cause symptoms like shortness of breath, cough, itchy eyes, or rhinitis. Apart from preventive measures and pharmacological treatment, also non‐pharmacological interventions have been suggested to reduce symptoms. The objective of this work was to review studies investigating the effectiveness of non‐pharmacologic interventions to reduce allergic symptoms. Methods: PubMed, EMBASE, and CENTRAL were systematically reviewed in July 2018 and April 2020. Several authors worked on the screening of titles, abstracts, and full texts. One author for each literature search performed the data extraction and the risk of bias assessment. Studies were included if they met the inclusion criteria defined by the PECOs. Studies which investigating the effect of non‐pharmacologic interventions on patients with allergic rhinitis were included. Results: Twenty‐nine studies investigating eleven types of non‐pharmacologic interventions to avoid and reduce allergic symptoms due to pollen exposure were included in this review. Out of all studies, seven studies addressed nasal rinsing and 22 included acupuncture, air filtering, artisanal tears, individual allergen avoidance advice, various nasal applications, self‐hypnosis, rhinophototherapy, and wraparound sunglasses. Conclusion: Most studies had a high risk of bias and small sample sizes. There were only a few high‐quality studies that give hints about the effectiveness of non‐pharmacological interventions. For future research, more high‐quality studies are required to confirm the effectiveness of simple, safe, and cost‐effective interventions. [ABSTRACT FROM AUTHOR]

Background Atopic diseases are among the most common chronic conditions in childhood. Causes of allergies are manifold. The aim of this paper is to evaluate risk factors for atopic diseases and unremitting wheeze and to examine if there is an association between measles, mumps and rubella (MMR) vaccination and atopic dermatitis, asthma and unremitting wheeze in Bavarian pre-schoolers. Methods Parents filled out a questionnaire on children's health and environmental and socioeconomic factors. The questionnaire was administered within the Health Monitoring Units in a cross-sectional study in Bavaria, Germany (2014/2015). Data on vaccinations were obtained via the School Entrance Examination, a mandatory examination for pre-school children in Bavaria. Rates of influential factors of atopic diseases and wheeze, MMR and DTP (diphtheria, pertussis and tetanus) vaccination were calculated for all children stratified by health outcomes. To examine if there is an association between MMR vaccination and health outcomes, a multiple logistic regression analysis was performed. Results Data were available for 3237 individuals. Symptoms and diseases were more frequent in boys. Higher parental education was associated with a higher prevalence of atopic dermatitis. There were no significant associations between any of the health outcome groups and MMR vaccination in the multiple logistic regression models with adjustment for potential confounders. Conclusions The present study is in line with the current state of research that MMR vaccination is not associated with atopic diseases. [ABSTRACT FROM AUTHOR]

Introduction: Children's skin is particularly susceptible to the carcinogenic effects of ultraviolet radiation. Young children are dependent on sun protection measures taken by parents and other caregivers., Objectives: The aim of the study is to evaluate parental sun protection behavior and sun protection measures at preschool at two points in time (2010/11 and 2018/19) in Bavaria and to test for a secular trend., Methods: Two cross-sectional surveys were carried out. For each survey, more than 4,000 parents of preschoolers completed a self-administered questionnaire about parental sun protection behavior and sun protection measures at preschool. To identify possible associations between parental sun protection behavior and sociodemographic characteristics, logistic regression analysis was carried out., Results: In the survey of 2018/19, six out of eight sun protection measures are adequately applied by over two-thirds of the parents. Two out of eight sun protection measures are adequately applied by less than one-third of the parents. Those two measures are aligning sun protection to actual UV index and preschoolers wearing sunglasses. The comparison of the study population of the survey of 2010/11 and of 2018/19 shows an improvement in parental sun protection behavior for seven out of eight sun protection measures. In both surveys more than 80% of parents state that preschool staff ensures preschoolers wear sun hats and sunscreen outside on sunny days., Conclusions: Future campaigns should focus on the use of sunglasses and promote the UV index, as these sun protection measures are used very little.

Background: After decades of rising prevalence of atopic and airway-related diseases, studies showed stagnating prevalence in western industrialised countries. Objective of this study is to analyse the time trend of prevalence of atopic diseases and airway-related symptoms among Bavarian children before starting primary school., Materials and Methods: Five cross-sectional studies from 2004/2005, 2006/2007, 2012/2013, 2014/2015 and 2016/2017 took place in urban and rural regions in Bavaria, Germany. Using standardized parent questionnaires children's atopic diseases and airway-related symptoms were surveyed. Logistic regression analysis (Bonferroni correction: adjusted significance level 0.005) was performed to analyse prevalence of symptoms and diseases from 2004 to 2017 for time trends., Results: The surveys included 27384 Bavarian children aged 5-6 years (52.6% male). In all children the calculated 12-month prevalence of symptoms '≥four episodes of wheeze' (p-value = .0880) and 'rhinoconjunctivitis' (p-value = .3994) reported by parents stagnated, whereas 'wheeze' (p-value<.0001; OR = 0.97; CI = [0.96-0.98]) and 'rhinitis' (p-value = .0007; OR = 0.98; CI = [0.97-0.99]) decreased. In all children the calculated lifetime prevalence of physician-diagnosed 'asthma' (p-value = .5337), and 'hay fever' (p-value = .8206) stagnated, whereas of 'bronchitis' (p-value<.0001; OR = 0.98; CI = [0.98-0.99]) decreased over time. The calculated lifetime prevalence of physician-diagnosed 'atopic eczema' (p-value = .0002; OR = 0.98; CI = [0.97-0.99]) decreased in all children, whereas the calculated 12-month prevalence of the symptom 'itchy rash' increased (p-value = .0033; OR = 1.07; CI = [1.05-1.08]) over time., Conclusions: Several calculated prevalence of children's atopic diseases and airway-related symptoms reported by parents stagnated in a subgroup of Bavarian children before starting primary school between 2004 and 2017. The time trend of prevalence in 'wheeze', 'rhinitis' and 'bronchitis' decreased. Prevalence of 'atopic eczema' decreased over time, whereas 'itchy rash' increased., (Copyright © 2021 Elsevier Ltd.
