BACKGROUND Several indicators suggest that food allergy in infants is common and possibly increasing. Few studies have used oral food challenge to measure this phenomenon at the population level. OBJECTIVE To measure the prevalence of common IgE-mediated childhood food allergies in a population-based sample of 12-month-old infants by using predetermined(More)
Asthma is a major public health issue. The co-occurrence of the high prevalence of asthma and vitamin D deficiency documented globally in recent decades has prompted several investigations into a possible association between the two conditions. The objective of this paper was to synthesize the evidence from studies that have measured the association between(More)
AIMS We aimed to assess the prevalence and types of precautionary labelling statements for common food allergens on the packages of products for which these allergens were not listed as an ingredient and to investigate the uptake of the Voluntary Incidental Trace Allergen Labelling, a new risk management tool developed in Australia to assist with declaring(More)
BACKGROUND There is a substantial body of evidence on the epidemiology of allergic conditions, which has advanced the understanding of these conditions. We aimed to systematically identify systematic reviews and meta-analyses on the epidemiology of allergic diseases to assess what has been studied comprehensively and what areas might benefit from further(More)
BACKGROUND Infant feeding guidelines have long recommended delaying introduction of solids and allergenic foods to prevent allergy in high-risk infants, despite a paucity of evidence. OBJECTIVE We aimed to determine whether confirmed egg allergy in 12-month-old infants is associated with (1) duration of breast-feeding and (2) ages of introducing egg and(More)
IgE-mediated food allergy is a transient condition for some children, however there are few indices to predict when and in whom food allergy will resolve. Skin prick test (SPT) and serum-specific IgE levels (sIgE) are usually monitored in the management of food allergy and are used to predict the development of tolerance or persistence of food allergy. The(More)
PURPOSE OF REVIEW The purpose of the present review is to describe the epidemiology of food-induced, medication-induced, drug-induced, and insect sting-induced anaphylaxis; to summarize recent changes in the incidence of anaphylaxis internationally; and to discuss recent insights into potential risk factors for anaphylaxis. RECENT FINDINGS Recent studies(More)
BACKGROUND Ninety-five percent positive predictive values (PPVs) provide an invaluable tool for clinicians to avoid unnecessary oral food challenges. However, 95% PPVs specific to infants, the age group most likely to present for diagnosis of food allergy, are limited. OBJECTIVE We sought to develop skin prick test (SPT) and allergen-specific IgE (sIgE)(More)
BACKGROUND A recent randomized trial (the Learning Early About Peanut Allergy [LEAP] study) provided evidence that earlier dietary peanut introduction reduces peanut allergy prevalence in high-risk infants. However, questions remain as to how to identify and target the "at-risk" population to facilitate timely introduction of peanut. OBJECTIVE We sought(More)
The rise in food allergy prevalence in developed countries is evident from anecdotal reports but has been difficult to document and until recently good quality prevalence data were lacking. Although most emerging risk factors seem related to the "modern lifestyle" the reasons for the rise in food allergy prevalence remain poorly understood. The incidence of(More)
