Chau K, Chau N. Untreated Allergy Among Middle School Students: Associations with Socioeconomic Adversities and Academic, Behavior, and Health Difficulties. THE JOURNAL OF SCHOOL HEALTH 2024; 94:717-726. [PMID: 38423524 DOI: 10.1111/josh.13447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 01/14/2024] [Accepted: 01/28/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Many adolescents with allergy do not receive physician treatment (allergyuntreated). We explored its association with socioeconomic adversities and academic-behavior-health difficulties, which remain unaddressed. METHODS This cross-sectional school-based-population study compared the above factors of middle-school adolescents with allergyuntreated and those with treated allergy (allergytreated) (mean age = 13.5 ± 1.2) from north-eastern France. Participants completed a questionnaire collecting socioeconomic adversities (nonintact family, low parents' education, insufficient family income, poor social support, suffered verbal/physical violence, and sexual abuse), low academic performance, excessive screen time, substance use, sleep difficulty, poor physical health, depressive symptoms, suicide attempt, poor quality of life, and allergytreated/allergyuntreated. RESULTS Logistic regression models showed that allergyuntreated was associated with all the factors considered (sex-age-class-level-adjusted odds ratio (saclOR) reaching 3.94, p < .001) and the risk score (number of main criteria: suffered sexual abuse, excessive screen time, poor quality of life, cannabis use, low parents' education, and poor social support): saclOR 4.75, 9.23, 15.64, and 31.73 (p < .001) for risk scores 1, 2, 3, and ≥4, versus risk score = 0 (pseudo-R2 = 11.1%). CONCLUSIONS Socioeconomic adversities and academic-behavior-health difficulties may be used to detect adolescents with allergyuntreated for care.

Frequency of food allergy in Europe: An updated systematic review and meta-analysis. Allergy 2023; 78:351-368. [PMID: 36271775 PMCID: PMC10099188 DOI: 10.1111/all.15560] [Citation(s) in RCA: 61] [Impact Index Per Article: 61.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 10/14/2022] [Accepted: 10/18/2022] [Indexed: 02/01/2023]
Abstract
Food allergy (FA) is increasingly reported in Europe, however, the latest prevalence estimates were based on studies published a decade ago. The present work provides the most updated estimates of the prevalence and trends of FA in Europe. Databases were searched for studies published between 2012 and 2021, added to studies published up to 2012. In total, 110 studies were included in this update. Most studies were graded as moderate risk of bias. Pooled lifetime and point prevalence of self-reported FA were 19.9% (95% CI 16.6-23.3) and 13.1% (95% CI 11.3-14.8), respectively. The point prevalence of sensitization based on specific IgE (slgE) was 16.6% (95% CI 12.3-20.8), skin prick test (SPT) 5.7% (95% CI 3.9-7.4), and positive food challenge 0.8% (95% CI 0.5-0.9). While lifetime prevalence of self-reported FA and food challenge positivity only slightly changed, the point prevalence of self-reported FA, sIgE and SPT positivity increased from previous estimates. This may reflect a real increase, increased awareness, increased number of foods assessed, or increased number of studies from countries with less data in the first review. Future studies require rigorous designs and implementation of standardized methodology in diagnosing FA, including use of double-blinded placebo-controlled food challenge to minimize potential biases.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL HEALTH RESEARCH 2022; 32:1962-1972. [PMID: 34155935 DOI: 10.1080/09603123.2021.1929873] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Accepted: 05/05/2021] [Indexed: 06/13/2023]
Abstract
The study explored the associations between maternal exposure to air pollution during different trimesters and allergic diseases including asthma, allergic rhinitis, allergic conjunctivitis or/and eczema. Individual exposure to air pollutants was assessed by an inverse distance weighted (IDW) method using daily concentrations of SO2, NO2, PM10, and PM2.5 from air quality monitoring stations. Multiple logistic regression model was performed to estimate the associations between air pollution during each trimester of pregnancy and childhood allergic diseases. A total of 332 children (51.3%) were reported by their parents having been diagnosed with allergic diseases. After adjusting for covariates, allergic diseases were significantly associated with per interquartile range (IQR) increase in NO2, PM10, PM2.5 during the second trimester with odds ratios (ORs) and 95% confidence intervals (95%CIs) being 1.292 (1.005,1.662), 1.210 (1.042,1,405) and 1.270 (1.004,1.606), respectively. These findings suggest that maternal exposure to certain air pollutants during pregnancy, especially in the second trimester, is associated with childhood allergic diseases.

World Allergy Organ J 2022; 15:100625. [PMID: 35145605 PMCID: PMC8802121 DOI: 10.1016/j.waojou.2022.100625] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 11/08/2021] [Accepted: 01/05/2022] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Allergies have an enormous individual and economic impact worldwide and affect more than one quarter of the population in Germany. Various factors influence the development of allergies: besides genetic predisposition the environment in which a person is raised and living also plays a role. The aim of the study was to evaluate differences in allergy prevalence in relation to age, sex, occupation, and living area (settlement structures). METHODS A cross-sectional study using a paper-based questionnaire about allergies was performed at the Munich Oktoberfest 2016. Participants were divided into 4 occupational groups and compared using descriptive statistics and multiple regression. RESULTS Overall, 2701 individuals (mean age 51.9 ± 15.3 years; 53.5% women) participated in the study. The overall rate of any self-reported allergy was 27.3% in the study population, in which women were more likely to be affected than men (OR = 1.82; 95% CI [1.50; 2.22]). Compared to farmers, all other occupational groups had a higher risk of reporting pollen allergies. Participants from rural areas (OR = 0.38; 95% CI [0.26; 0.58]) and suburban areas (OR = 0.44; 95% CI [0.30; 0.64]) were significantly less affected by allergies than participants from urban areas. Around 45.2% of the participants affected by allergies reported not receiving any treatment at all. CONCLUSION Differences in the self-reported prevalence of allergies were shown for age groups, sex, living area, and occupation. Especially the reported pollen allergy prevalence ranged widely between different occupations, indicating that those individuals with an occupational exposure to pollen may have a lower risk than indoor workers. Overall, there remains a high need for sufficient treatment of allergies.

Abstract
BACKGROUND The disease burden of actinic keratoses and keratinocyte carcinoma can be reduced by primary and secondary prevention. However, these measures are often poorly received, especially among the high-risk group of outdoor workers. OBJECTIVES The aim of this follow-up study was to investigate whether an improvement in sun protection and awareness of skin changes could be observed among the study population, especially outdoor workers, one year after a prevention campaign focusing on this topic. MATERIALS AND METHODS In 2017, all participants who initially participated in a study at the Bavarian Central Agricultural Festival 2016 and agreed to participate in the follow-up study were contacted by mail and received the same questionnaire and evaluation questions regarding possible behavioral changes. RESULTS A total of 400 people took part in the follow-up study (response rate 52.8%). Of the 240 outdoor workers, 45.0% said they were more conscious of protecting themselves from the sun and 68.8% said they were more aware of skin changes. About 85.0% of outdoor workers indicated that they would consult a dermatologist earlier and 65.8% desired further prevention campaigns regarding skin cancer and sun protection. CONCLUSION Overall, the majority of participants reported that they had improved sun protection behavior and awareness of skin changes after the intervention. Based on the participants' self-disclosure, especially outdoor workers tended to use sun protection measure more frequently. These findings underline the importance of target group-oriented awareness and prevention campaigns to reduce the burden of skin cancer.

World Allergy Organ J 2019; 12:100039. [PMID: 31312341 PMCID: PMC6610241 DOI: 10.1016/j.waojou.2019.100039] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 05/16/2019] [Accepted: 05/17/2019] [Indexed: 12/01/2022] Open
Abstract
Background Hymenoptera venom sensitization in highly exposed individuals frequently requires risk assessment for future severe sting reactions. In this study, we determined the prevalence of Hymenoptera venom sensitization in individuals who hunt and fish and analyzed possible correlations between the severity of sting reactions and the IgE sensitization profile. Methods In this cross-sectional study, paper-based, self-filled questionnaires about previous insect stings and sting reactions were obtained from individuals who hunt and fish in Bavaria, Germany. Blood samples were taken and analyzed for the levels of tryptase, total IgE and IgE to honey bee (i1) and wasp (13) venom, the recombinant allergens rApi m 1, rApi m 2, rApi m 3, rApi m 5, rApi m 10, rVes v 1, rVes v 5, and the CCD marker molecule MUXF3. Odd ratios (ORs) for sensitization and anaphylaxis and Pearson's correlations for the different allergens were calculated. Results Of 257 participants, 50.2% showed a sensitization to honey bee venom (i1), and 58.4% showed sensitization to wasp venom (i3). A total of 98.4% of participants claimed to have been stung at least once. Anaphylaxis was reported in 18.7%, and a local sting reaction was reported in 18.3%. The highest sensitization rates were found for whole venom extracts, sensitization to any of the available recombinant allergens exceeded sIgE levels to honeybee venom (i1) in 28.5% and to wasp venom (i3) in 52.9% of participants. Participants with a history of more than 5 stings showed a higher risk for anaphylaxis. Conclusions Sensitization to Hymenoptera venom and their recombinant allergens are present in the majority of individuals who hunt and fish. Sensitization to distinct recombinant allergens does not necessarily affect the severity of sting reactions including anaphylaxis. A meticulous medical history of the number of previous stings as well as systemic reactions remains essential.
