Obesity among men has been linked to an increased risk of pneumonia, according to a study conducted by Danish researchers. The authors, however, cautioned that the link occurs more strongly with diseases associated with obesity, rather than with obesity itself. Previous studies on the relationship between the two conditions had been plagued by inconsistent results. To gain a better understanding of the link, authors looked at data from the Danish Diet, Cancer, and Health Study, which recorded samples from nearly 50,000 Danes.

Statistical analysis of the sample showed that moderately obese men (those with a Body Mass Index (BMI) between 30 and 34.9) had a 40 percent higher risk of developing pneumonia compared to those who were of normal weight (a BMI of less than 24.9). Morbidly obese men (those with a BMI greater than 35) were seen to be twice as likely to suffer from pneumonia. There was no risk difference seen in women.
Authors of the study are unsure why there is a gender difference, but postulate that fat distribution may be a major factor. An apple shape – which is usually the shape men form when they gain weight – can reduce ventilation in the lungs.
However, obesity was seen as a working factor for most of the comorbidities of pneumonia. For example, diabetes (which several studies conclude is related to weight) has also been associated with a 25 to 75 percent increased risk for pneumonia.

This study was concluded in 2010 and many health professionals have asked for newer research to be conducted. With more advanced medical technologies, scientists can determine the exact relationship between obesity and pneumonia.
