Prevalence and Characteristics of Shellfish Allergy in the Pediatric Population of the United States.

ABSTRACT:

Background

Shellfish allergy (SA) is one of the most common food allergies causing anaphylaxis in adults and children. There are limited data showing the prevalence of SA in US children.

Objective

To determine the prevalence and reaction characteristics of SA in the US pediatric population.

Methods

A cross-sectional food allergy prevalence survey was administered via phone and the Web by the National Opinion Research Center at the University of Chicago from 2015 to 2016. Point prevalence SA estimates, complex survey weighted proportions, and 95% CIs were determined. Relative proportions of demographic characteristics were compared using weighted Pearson ?² statistics.

Results

The prevalence of SA was 1.3% (95% CI, 1.1-1.5), with more children allergic to crustaceans (1.2%; 95% CI, 1.0-1.3) than to mollusks (0.5%; 95% CI, 0.4-0.6). Mean ages of shellfish, crustacean, and mollusk allergy diagnoses were 5.0 (95% CI, 4.4-5.6), 5.1 (95% CI, 4.6-5.6), and 7.7 (95% CI, 5.7-9.7) years, respectively. More than half (54.9%; 95% CI, 48.1-61.4) of pediatric patients with SA had more than 1 lifetime food allergy-related emergency room visit, but only 45.7% (95% CI, 39.2-52.4) carried an epinephrine autoinjector. Children with SA were more likely to be black/Hispanic/Latino and have comorbid asthma, allergic rhinitis, or a parental history of asthma, environmental, or other food allergies (P < .001).

Conclusions

The epidemiology of SA in the US pediatric population shows that crustacean allergy is more common than mollusk allergy. A disparity in SA children and epinephrine autoinjector carriage exists. Results from this study will lead to increased awareness of the need for detailed histories, specific diagnostic tests, and rescue epinephrine for anaphylaxis in US children with SA.

Project description:ImportanceSesame allergy is of growing concern in the United States. The US Food and Drug Administration recently issued a request for epidemiological data on the prevalence and severity of sesame allergies in the United States to inform possible regulatory action requiring sesame to be labeled as an allergen on packaged foods.ObjectiveTo provide current estimates of the prevalence, severity, distribution, and clinical characteristics of sesame allergy in the United States.Design, setting, and participantsThis cross-sectional study assessed findings of web- and telephone-based food allergy questionnaires. Study participants were first recruited from NORC (National Opinion Research Center) at the University of Chicago's probability-based AmeriSpeak panel, and additional participants were recruited through Survey Sampling International. Surveys were administered to a nationally representative sample of 51 819 US households from October 1, 2015, through September 31, 2016. Responses for 40 453 adults and 38 408 children were included in the analysis. Data were analyzed from January 1, 2017, through May 1, 2019.ExposuresDemographic and allergic characteristics of participants.Main outcomes and measuresSelf-reported sesame allergy was the main outcome and was considered convincing if reported symptoms to sesame-allergic reactions were consistent with an IgE-mediated reaction. Diagnostic history of specific allergens and use of food allergy-related health care services were also primary outcomes.ResultsUsing survey responses from 78 851 individuals, an estimated 0.49% (95% CI, 0.40%-0.58%) of the US population reported a current sesame allergy, whereas 0.23% (95% CI, 0.19%-0.28%) met symptom-report criteria for convincing IgE-mediated allergy. An additional 0.11% (95% CI, 0.08%-0.16%) had a sesame allergy reported as physician diagnosed but did not report reactions fulfilling survey-specified convincing reaction symptoms. Among individuals with convincing IgE-mediated sesame allergy, an estimated 23.6% (95% CI, 16.9%-32.0%) to 37.2% (95% CI, 29.2%-45.9%) had previously experienced a severe sesame-allergic reaction, depending on the definition used, and 81.6% (95% CI, 71.0%-88.9%) of patients with convincing sesame allergy had at least 1 additional convincing food allergy. Roughly one-third of patients with convincing sesame allergy (33.7%; 95% CI, 26.3%-42.0%) reported previous epinephrine use for sesame allergy treatment.Conclusions and relevanceThese data indicate a substantial burden of sesame allergy and provide valuable context to physicians and policy makers in their efforts to evaluate and reduce the public health burden of sesame allergy. Moreover, the relatively low rates of physician diagnosis observed among individuals with convincing IgE-mediated sesame allergy seem to indicate the need for clear diagnosis and appropriate management.

Project description:ImportanceTelehealth services, which allow patients to communicate with a remotely located clinician, are increasingly available; however, prevalence of telehealth use, including videoconferencing visits, remains unclear.ObjectiveTo measure the use of and willingness to use telehealth modalities across the US population.Design, setting, and participantsThis survey study, conducted between February 2019 and April 2019, asked participants about their use of different telehealth modalities, reasons for not using videoconferencing visits, and willingness to use videoconferencing visits. Questions were continuously posed to panel members and closed after 2555 responses were obtained, at which point 3932 panel members had been invited, for a 65.0% response rate.ExposuresDemographic characteristics (ie, age, sex, race, rural/urban residency, education level, and income).Main outcomes and measuresSelf-reported use of specific telehealth modalities, reasons for nonuse, and willingness to use videoconferencing in the future.ResultsA total of 2555 individuals completed the survey with a mean (SD) age of 57.2 (14.2) years; 1453 respondents (weighted percentage, 51.9%) were women, and 2043 (weighted percentage, 73.4%) were White individuals. Overall, 1343 respondents (weighted percentage, 50.8%) reported use of a nontelephone telehealth modality, ranging from 873 respondents (weighted percentage, 31.9%) for patient portals and 89 respondents (weighted percentage, 4.2%) for videoconferencing visits. Although 1309 respondents (weighted percentage, 49.2%) overall answered that they were willing or very willing to use videoconferencing visits, respondents who were Black individuals (OR, 0.58; 95% CI, 0.38-0.91), aged older than 65 years (OR, 0.51; 95% CI, 0.40-0.66), or had less education (high school or less vs advanced degrees: OR, 0.37; 95% CI, 0.25-0.56) were less likely to express willingness.Conclusions and relevanceDespite the focused policy attention on videoconferencing visits, the results of this survey study suggest that other forms of telehealth were more dominant prior to 2020. Targeted efforts may be necessary for videoconferencing visits to reach patient groups who are older or have less education, and payer policies supporting other forms of telemedicine may be appropriate to enhance access.

Project description:ImportanceHearing loss is one of the most prevalent chronic conditions in the United States and has been associated with negative physical, social, cognitive, economic, and emotional consequences. Despite the high prevalence of hearing loss, substantial gaps in the utilization of amplification options, including hearing aids and cochlear implants (CI), have been identified.ObjectiveTo investigate the contemporary prevalence, characteristics, and patterns of specialty referral, evaluation, and treatment of hearing difficulty among adults in the United States.Design, setting, and participantsA cross-sectional analysis of responses from a nationwide clustered representative sample of adults who participated in the 2014 National Health Interview Survey and responded to the hearing module questions was carried out.Main outcomes and measuresData regarding demographics as well as self-reported hearing status, functional hearing, laterality, onset, and primary cause of the hearing loss were collected. In addition, specific data regarding hearing-related clinician visits, hearing tests, referrals to hearing specialist, and utilization of hearing aids and CIs were analyzed.ResultsAmong 239.6 million adults, 40.3 million (16.8%) indicated their hearing was less than "excellent/good," ranging from "a little trouble hearing" to "deaf." The mean (SD) age of participants was 47 (0.2) years with 48.2% being men and 51.8% women. Approximately 48.8 million (20.6%) had visited a physician for hearing problems in the preceding 5 years. Of these, 32.6% were referred to an otolaryngologist and 27.3% were referred to an audiologist. Functional hearing was reported as the ability to hear "whispering" or "normal voice" (225.4 million; 95.5%), to "only hear shouting" (8.0 million; 3.4%), and "not appreciating shouting" (2.8 million; 1.1%). Among the last group, 5.3% were recommended to have a CI, of which 22.1% had received one. Of the adults who indicated their hearing from "a little trouble hearing" to being "deaf," 12.9 million (32.2%) had never seen a clinician for hearing problems and 11.1 million (28.0%) had never had their hearing tested.Conclusions and relevanceThere are considerable gaps between self-reported hearing loss and patients receiving medical evaluation and recommended treatments for hearing loss. Improved awareness regarding referrals to otolaryngologists and audiologists as well as auditory rehabilitative options among clinicians may improve hearing loss care.

Project description:In 2006, the Centers for Medicare & Medicaid Services, which administers the Medicare program in the United States, launched the Chronic Condition Data Warehouse (CCW). The CCW contains all Medicare fee-for-service (FFS) institutional and non-institutional claims, nursing home and home health assessment data, and enrollment/eligibility information from January 1, 1999 forward for a random 5% sample of Medicare beneficiaries (and 100% of the Medicare population from 2000 forward). Twenty-one predefined chronic condition indicator variables are coded within the CCW, to facilitate research on chronic conditions. The current article describes this new data source, and the authors demonstrate the utility of the CCW in describing the extent of chronic disease among Medicare beneficiaries. Medicare claims were analyzed to determine the prevalence, utilization, and Medicare program costs for some common and high cost chronic conditions in the Medicare FFS population in 2005. Chronic conditions explored include diabetes, chronic obstructive pulmonary disease (COPD), heart failure, cancer, chronic kidney disease (CKD), and depression. Fifty percent of Medicare FFS beneficiaries were receiving care for one or more of these chronic conditions. The highest prevalence is observed for diabetes, with nearly one-fourth of the Medicare FFS study cohort receiving treatment for this condition (24.3 percent). The annual number of inpatient days during 2005 is highest for CKD (9.51 days) and COPD (8.18 days). As the number of chronic conditions increases, the average per beneficiary Medicare payment amount increases dramatically. The annual Medicare payment amounts for a beneficiary with only one of the chronic conditions is $7,172. For those with two conditions, payment jumps to $14,931, and for those with three or more conditions, the annual Medicare payments per beneficiary is $32,498. The CCW data files have tremendous value for health services research. The longitudinal data and beneficiary linkage within the CCW are features of this data source which make it ideal for further studies regarding disease prevalence and progression over time. As additional years of administrative data are accumulated in the CCW, the expanded history of beneficiary services increases the value of this already rich data source.
