Perceived increased prevalence and levels of awareness of food allergy has become a global phenomenon, making it a major public health concern. Although little is known about its etiology or prevalence, substantial variation in prevalence on a global scale is evident. Studies on food allergy in Asia are reporting an increase in prevalence, particularly in economically developed regions like Hong Kong. Interestingly, risk perception studies have found that Canadians’ perceived prevalence of food allergy surpasses systematic estimates. Moreover, Canadian immigrants are more likely to rate the risk of food allergy as “high” compared to non-immigrants. To explore these issues further, qualitative interviews were conducted with key informants (n=3) and allergic individuals of Asian descent (n=18) in order to capture their lived experience with food allergies. Interviews lasted 30 minutes on average and they were tape recorded and transcribed verbatim for subsequent thematic analysis using QSR International’s NVivo 9. Results are organized around four major themes: perceived prevalence, risk perception, management and coping, and quality of life. With respect to perceived prevalence and risk, participants found food allergies to be more common in Canada than in Asia. Participants also agreed that having a food allergy is more manageable in Canada as a result of the policy environment (e.g., food labelling and school board policies). In addition, participants had dealt with skepticism and disbelief about their food allergy in Asia, impacting their quality of life. These findings demonstrate the need to recognize the varied impacts and experiences of food allergy among new Canadians, given that immigrants represent a large and growing proportion of the Canadian population.

Global research on psychosocial factors related to food allergies and youth have increased significantly over the last decade. A plethora of countries provide literature indicating adolescents with food allergies experience social isolation, depression, anxiety, and fear. Most of the literature however favors parental perspectives with limited studies exploring adolescent subjective perspectives. The purpose of this hermeneutic phenomenological study was to explore the lived experiences of adolescents living with food allergies; the goal was to bring awareness to the ascribed meaning of food allergies from the perspective of adolescents and the impact of living with food allergies from day-to-day. Watson’s caring science and Erikson’s psychosocial theory were guiding frameworks for the study with story theory used to guide individual semi-structured interviews (n=14) (11-14 years). Analysis of data entailed various steps congruent with Interpretive Phenomenological Analysis. Four superordinate themes emerged from the data: (1) Living with Restraints: A Way of Life, (2) Managing Exposure, (3) Experiencing Stigma, and (4) Experiencing Lack of Knowledge. Results indicated adolescents living with food allergies have unique experiences that contribute to psychosocial upheavals and that traditional biological management may be too simplistic for promoting whole adolescent well-being and healthy development. Study findings may contribute to evidence-based interventions that nurture care for the whole adolescent. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

A proposta deste estudo é verificar a expressão de fenótipos linfocitários, as citocinas padrão Th1 e Th2, e a IgE total e específica em crianças com APLV, crianças atópicas (AC) e não atópicas (NAC) e suas respectivas mães.Foram colhidas amostras de sangue periférico para tipagem de linfócitos por citometria de fluxo, e dosadas as citocinas séricas, por CBA (Cytometric Bead Array) e dosado a IgE total e específica para as proteínas caseína, α lactoalbumina e β lactoglobulina , das crianças e suas mães nos grupos APLV, AC e NAC.Nas crianças do grupo APLV o início dos sintomas foi por volta dos 5,1 meses de idade, com idade média de 17,25 meses (sd=14,8 meses). As crianças e suas mães dos grupos alérgicos (APLV e AC) mostraram maior número de linfócitos CD4+CD25+ (p<0,05) em relação àquelas do grupo não alérgico (NAC), mas sem diferença significativa (p>0,05) entre os grupos APLV e AC. O grupo APLV mostrou maior tendência à presença do fenótipo CD25. As concentrações séricas das citocinas IL4, IL5, IL10, IL2, TNF-α e IFN-γ, entre os grupos estudados, não apresentaram diferenças estatísticas significantes (p>0,05), porém houve uma maior tendência à expressão da IL10 nas crianças do grupo APLV. A IgE total ficou mais evidente no grupo APLV do que nos demais grupos, e os principais alérgenos foram a α-lactoalbumina e β lactoglobulina. As crianças com alergia ao leite de vaca apresentam uma maior positividade de linfócitos CD4+CD25+, presença de IgE total e expressão de IL10 in vivo o que também pode sugerir um meio de controle da alergia para desenvolver tolerância à proteína do leite de vaca... / The allergy to cow‟s milk protein (CMA) is common in the first year of life and it is difficult to acknowledge and diagnose it. This study aims to verify the expression of lymphocyte phenotypes, detect the TH2 and TH1 pattern cytokines and the total and specific IgE in CMA children, in atopic (AC) and non-atopic (NAC) children and their respective mothers. Samples of peripheral blood were collected in order to type the lymphocytes by flow cytometry, dosed the serial cytokines by Cytometric Bead Array (CBA) and dosed the total IgE and specific IgE for the casein, α lactoalbumin and β lactoglobulin proteins of the children and their mothers in the CMA, AC and NAC groups. In the CMA children the symptoms first occurred around 5,1months old, with the average age of 17.25 months (sd=14.8 months). The children and their mothers from the allergic group (CMA and AC) showed significantly presence of CD4+CD25+ lymphocytes (p<0.05) higher than the non-allergic group (NAC), but without any significant difference (p>0.05) between the CMA and AC groups, although there was a tendency to an increase presence of these cells in the CMA group. The serial concentration of the IL4, IL5, IL10, IL2, TNF-α and IFN-γ cytokines, among the studied groups, did not present significant statistical difference (p>0.05), however, there was a tendency to an increase expression of IL10 in the CMA group of children. The total IgE was more evident in the CMA group than in the other ones and the main proteins which caused allergic reactions were α-lactoalbumin e β lactoglobulin. The children with cow‟s milk allergy presented a higher positivity of CD4+CD25+ lymphocytes, higher total IgE and an increase expression of in vivo IL10, which may also suggest a means of control of the allergy to develop tolerance to the cow‟s milk proteins...
