The global incidence of paediatric inflammatory bowel disease (IBD) is increasing. Much of the evidence attesting to this has arisen from North America and Europe. There is a relative paucity of information on the epidemiology of paediatric IBD in the Southern Hemisphere. This study aimed to document the prospectively-collected incidence of paediatric IBD in New Zealand in 2015.
All patients under 16 years of age and diagnosed with IBD in New Zealand between 1 January 2015 and 31 December 2015 were identified. Demographic and disease phenotypic details were collected and entered into a secure database. Age-specific population data for New Zealand were obtained and national incidence rates for IBD and its sub-types were calculated.
The prospectively-calculated incidence of paediatric IBD, Crohn's disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU) in New Zealand in 2015 were 5.2 (95% CI 3.9-6.8), 3.5 (2.4-4.8), 1.0(0.5-1.8) and 0.7(0.3-1.4) per 100 000 children, respectively.
Incidence rates of paediatric IBD in New Zealand are comparable to the highest rates published in the literature from Western Europe and North America. Ongoing prospective ascertainment of the incidence of paediatric IBD is required to better understand the environmental factors which are accounting for this increase in disease burden.
This research output has an Altmetric Attention Score of 1. 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 January 2018.
All research outputs
#28,640,276
of 34,411,289 outputs
Outputs from Journal of Pediatric Gastroenterology & Nutrition
#6,582
of 7,258 outputs
Outputs of similar age
#300,988
of 370,744 outputs
Outputs of similar age from Journal of Pediatric Gastroenterology & Nutrition
#67
of 79 outputs
Altmetric has tracked 34,411,289 research outputs across all sources so far. This one is in the 9th percentile – i.e., 9% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,258 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 2nd percentile – i.e., 2% of its peers scored the same or lower than it.
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 370,744 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 79 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
