Anaphylaxis is a potentially life-threatening systemic allergic reaction.
We aimed to determine the incidence rate and causes of anaphylaxis during a 10-year period in Olmsted County, Minnesota.
Using the resources of the Rochester Epidemiology Project, a comprehensive records linkage system, we performed a population-based incidence study in Olmsted County, Minnesota, from 2001 through 2010. All cases with a diagnosis of anaphylactic shock and 20% of cases with related diagnoses were manually reviewed. The relationships of age group, sex, and year of anaphylaxis with incidence rates were assessed by fitting Poisson regression models.
Six hundred thirty-one cases of anaphylaxis were identified. The median age was 31 years (interquartile range, 19-44 years). The overall age- and sex-adjusted incidence rate was 42 (95% CI, 38.7-45.3) per 100,000 person-years. There was a significant increase in the overall incidence of anaphylaxis during the study period, with an average increase of 4.3% per year (P < .001). In addition, there was a 9.8% increase per year in the incidence rate of food-related anaphylaxis. Food-related anaphylaxis was most common in children aged 0 to 9 years, venom-related anaphylaxis was most common in those 20 to 39 years of age, and medication-related anaphylaxis was most common in those 30 to 39 years of age.
The overall incidence rate of anaphylaxis was 42 per 100,000 person-years from 2001-2010 in Olmsted County, Minnesota. The incidence of anaphylaxis increased over time, and several inciting triggers were uniquely associated with different age groups.
This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 April 2023.
All research outputs
#6,490,856
of 34,359,530 outputs
Outputs from The Journal of Allergy and Clinical Immunology
#5,833
of 14,534 outputs
Outputs of similar age
#73,346
of 344,073 outputs
Outputs of similar age from The Journal of Allergy and Clinical Immunology
#88
of 163 outputs
Altmetric has tracked 34,359,530 research outputs across all sources so far. Compared to these this one has done well and is in the 80th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 14,534 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 18.2. This one has gotten more attention than average, scoring higher than 59% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 344,073 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 78% of its contemporaries.
We're also able to compare this research output to 163 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
