    Obese, overweight with pneumonia have less mortality risks versus normal weight patients

    Obese, overweight with pneumonia have less mortality risks versus normal weight patients



    In what seems an obesity paradox-- a new study has found that the overweight and obese people who are hospitalized for pneumonia are more likely to survive as compared to the patients of a normal weight. The study was presented at 2018 European Congress on Obesity in Vienna, Austria.




    The study was conducted by Professor Shy-Shin Chang from Taipei Medical University Hospital, Taipei City, Taiwan, and colleagues to determine the impact of being overweight and obese on pneumonia patients, by using data from about 1.7 million patient episodes of pneumonia across 1000 hospitals in the USA.




    The prevalence of obesity is increasing steadily worldwide and pneumonia is one of the most common infectious diseases. Obesity prevalence is increasing steadily throughout the world's population in most countries and pneumonia is one of the most common infectious diseases; however, there is uncertainty about a relationship between the two. A previous meta-analysis determined that an 'obesity survival paradox' exists for pneumonia (where obese people had better survival), but high variability existed among these studies.


    For the study, the researchers used the Nationwide Readmission database of the US from 2013 to 2014 and identified patients hospitalized with pneumonia. A pneumonia-associated hospitalization was defined as one in which the discharge record listed a principal diagnosis of pneumonia or a secondary diagnosis of pneumonia if the principal diagnosis was respiratory failure or sepsis. Use of mechanical ventilation was used to stratify pneumonia of different severity. Hospitalized pneumonia patients were categorized into normal (body mass index [BMI] under 25), overweight BMI between 25 and 30), and obese (BMI over 30).




    For minimizing the baseline differences between patients with different body weight, the authors carried out a technique call propensity score (PS)-matched analysis. PS contains 41 variables including demographics, social economic status, chronic comorbidities, and severity of pneumonia. Patients were matched 1:1:1 using this technique across the three groups of normal weight, overweight and obese. The authors then used computer modeling on the PS-matched pairs to assess the association between body weight and 30-day in-hospital mortality.


    A total of 1,690,760 pneumonia hospitalization episode fulfilled the inclusion criteria, of which 17,992 were overweight, 195,889 were obese, and 1,476,879 were normal weight. To investigate whether there was a differential risk of 30- day mortality among different obese populations, the authors stratified patients into different subgroups and adjust the risk for mortality using PS score.


    Key Findings:




    • Compared with normal weight patients without the use of ventilator, overweight patients were 23% more likely to survive and obese patients 29% more likely to survive.

    • Similar results were obtained in the cohort of more serious pneumonia requiring the use of ventilator overweight and obese patients were 21% and 30% respectively more likely to survive than normal weight patients.

    • the survival benefit of obesity is consistent in all subgroups, patients with lower comorbidity burden/severity had substantially better survival.

    • being in the lowest co-morbidity quartile compared with the highest is associated with 53% improvement in survival, and being in the group with the lowest severity of pneumonia was associated with 67% improvement in survival compared with the highest severity.


    "Using a large and nationally representative sample of over 1,000 hospitals in the US, we found that increase in body mass index was significantly associated with improved survival in patients hospitalized with pneumonia. We also found that severity and comorbidity burden had a modifying effect on survival, concluded the authors.
