Abstract

Obesity, gastroesophageal reflux, and smoking have repeatedly been shown to be important and independent risk factors for adenocarcinoma of the esophagus (EAC) and of the gastroesophageal junction (GEJAC). There have been few attempts, however, to quantify the proportion of disease associated with these potentially modifiable factors. The authors have estimated the population attributable fraction of EAC and GEJAC attributable to obesity, symptoms of gastroesophageal reflux, and smoking using data from a population-based case-control study conducted in Australia between 2002 and 2005. Cases were patients with EAC (n = 364) or GEJAC (n = 425). Controls (n = 1,580) were randomly sampled from a population register. Combinations of smoking, body mass index (weight in kilograms divided by height in meters squared), and gastroesophageal reflux together accounted for 76% (95% confidence interval: 66, 84) of EAC cases and 69% (95% confidence interval: 58, 78) of GEJAC cases. Individually, high body mass index (≥30) and frequent acid reflux (≥1 time/week) accounted for the greatest proportions of EAC (23% and 36%, respectively), and smoking and frequent symptoms of acid reflux accounted for the greatest proportions of GEJAC (43% and 28%, respectively). The present study suggests that these cancers may be largely prevented by maintaining healthy body mass index, avoiding smoking, and controlling symptomatic gastroesophageal reflux.

Attention Score in Context

Attention Score in Context

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 18 October 2011.
All research outputs
#15,237,301
of 22,655,397 outputs
Outputs from American Journal of Epidemiology
#7,995
of 8,992 outputs
Outputs of similar age
#83,203
of 115,009 outputs
Outputs of similar age from American Journal of Epidemiology
#47
of 64 outputs
Altmetric has tracked 22,655,397 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,992 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.7. This one is in the 7th percentile – i.e., 7% 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 115,009 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 64 others from the same source and published within six weeks on either side of this one. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
