Abstract

This paper poses three questions: (1) Does mortality from natural causes spike around Christmas and New Year? (2) If so, does this spike exist for all major disease groups or only specialized groups? (3) If twin holiday spikes exist, need this imply that Christmas and New Year are risk factors for death? To answer these questions, we used all official U.S. death certificates, 1979-2004 (n = 57,451,944) in various hospital settings to examine daily mortality levels around Christmas and New Year. We measured the Christmas increase by comparing observed deaths with expected deaths in the week starting on Christmas. The New Year increase was measured similarly. The expected number of deaths was determined by locally weighted regression, given the null hypothesis that mortality is affected by seasons and trend but not by holidays. On Christmas and New Year, mortality from natural causes spikes in dead-on-arrival (DOA) and emergency department (ED) settings. There are more DOA/ED deaths on 12/25, 12/26, and 1/1 than on any other day. In contrast, deaths in non-DOA/ED settings display no holiday spikes. For DOA/ED settings, there are holiday spikes for each of the top five disease groups (circulatory diseases; neoplasms; respiratory diseases; endocrine/nutritional/metabolic diseases; digestive diseases). For all settings combined, there are holiday spikes for most major disease groups and for all demographic groups, except children. In the two weeks starting with Christmas, there is an excess of 42,325 deaths from natural causes above and beyond the normal winter increase. Christmas and New Year appear to be risk factors for deaths from many diseases. We tested nine possible explanations for these risk factors, but further research is needed.

Attention Score in Context

This research output has an Altmetric Attention Score of 102. 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 05 January 2016.
All research outputs
#46,751
of 5,477,001 outputs
Outputs from Social Science & Medicine
#31
of 3,348 outputs
Outputs of similar age
#1,130
of 240,467 outputs
Outputs of similar age from Social Science & Medicine
#1
of 74 outputs
Altmetric has tracked 5,477,001 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,348 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.5. This one has done particularly well, scoring higher than 99% 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 240,467 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 74 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 98% of its contemporaries.
