Food insecurity and food allergy in children: A cross-sectional study

Red Meat Hypersensitivity and Probable Alpha-Gal Syndrome: Prevalence Among Adolescents

INTRODUCTION

It is unknown whether late adolescents represent a particular risk group for the development of red meat hypersensitivity (RMH) and alpha-gal syndrome (AGS). This age group's physiological changes and eating habits could play a determining role. This study aimed to estimate the self-reported prevalence of RMH and probable AGS among late adolescents.

METHODS

A cross-sectional study analyzed a sample of 1992 Mexican adolescents between 15 and 18 years of age. The data were obtained with a previously validated questionnaire that asked about the clinical manifestations related to red meat intake. Confidence intervals at 95% (95% CI) were estimated for proportions.

RESULTS

In total, there were 19 adolescents with RMH, a prevalence of 1.0% (95% CI: 0.6-1.5%). The main red meats related to symptoms were pork (89.5%), beef (21.1%), lamb (10.5%), and mutton (5.1%). The most frequent manifestations of RMH were gastrointestinal (73.7%), respiratory (63.2%), and cutaneous (63.2%). Once the symptoms were grouped, there were two cases of urticaria (2/19, 10.5%) and six cases with probable anaphylaxis (6/19, 31.6%). Finally, three adolescents were considered probable cases of AGS, which represents a prevalence of 0.15% (95% CI: 0.1-0.4%).

CONCLUSION

Although the prevalence of RMH in late adolescents is low, early detection is justified because approximately one-third present with severe symptoms.

Psychosocial Impact of Food Allergy on Children and Adults and Practical Interventions

PURPOSE OF REVIEW

IgE- and non-IgE-mediated food allergies are increasing in prevalence in children and adults worldwide. A food allergy diagnosis can be associated with a sense of overwhelm and stress and commonly has a negative impact on quality of life.

RECENT FINDINGS

While there is an increased recognition of the psychosocial effects of food allergy, the current research reflects the experience of mostly White, well-educated wealthier populations. Some studies have now explored the psychosocial impact among other populations; however, further study is needed. It is important that physicians and allied health professionals screen for the potentially negative psychosocial effects of food allergy and provide education to promote safety and self-efficacy at each visit; however, time may be a limiting factor. Numerous validated questionnaires are now available to help assess the psychosocial impact of food allergies. Allergy-friendly foods are typically more expensive, and thus, it is imperative that physicians screen for food insecurity as well. Educational resources should be offered regarding living well with food allergies at each visit. For patients and families experiencing anxiety or food allergy burden that is difficult to manage, referral to a mental health provider should be considered. Resources regarding programs to help accessing safe foods should also be available. Further research is needed among diverse populations focusing on interventions to best support patients and families with food allergy.
