| Abstract |
Besides smoking, low or high body mass index (BMI) is associated with chronic lung disease (CLD). It is unclear how CLD is associated with BMI, whether smoking interacts with this association, and how the associations differ from the patterns known for lung cancer. Our population comprised 35,212 individuals aged 14-99, who participated in population-based surveys conducted in 1977-1993 in Switzerland (mortality follow-up until 2014). We categorized smokers into never, former, light, and heavy; and BMI into underweight, normal weight, overweight, and obese. Hazard ratios (HRs) were obtained with multivariable Cox proportional hazards models. CLD mortality was strongly associated with being underweight. This was mainly due to the effect in men (HR 5.04 [2.63-9.66]) and also prevailed in never smokers (HR 1.81 [1.11-3.00]). Obesity was also associated with CLD mortality (HR men: 1.37 [1.01-1.86], women: 1.39 [0.90-2.17]), but not with lung cancer mortality. In line with lung cancer, for CLD, the BMI-mortality association followed the same shape in all smoking categories, suggesting that this association was largely independent of smoking status. The shape of the BMI-mortality association was inversely linear for lung cancer but followed a U-shape for CLD. Further research should examine the potentially protective effect of obesity on lung cancer occurrence and the possibly hazardous impact of underweight on CLD development. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 06 June 2018.
All research outputs
#15,523,434
of 25,382,440 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,408
of 2,578 outputs
Outputs of similar age
#187,886
of 342,877 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#42
of 77 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,578 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one is in the 44th percentile – i.e., 44% 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 342,877 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 77 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.
