Houston (PTI): Obese people suffering from asthma are nearly five times more likely to be hospitalised for the condition as compared to non-obese people, a new study has said.
The first of its kind study surveyed 1,113 asthma patients above 35 years of age in America, while controlling risk factors like smoking, use of oral or inhaled medications, gastroesophageal reflux disorder, and demographics that might explain the obesity-asthma association.
"The big finding here is that even after adjusting for risk factors, obese adults were nearly five times more likely to be hospitalised for their asthma," said lead author David M Mosen of the Kaiser Permanente Center for Health Research at Denver in the US.
Previous studies have shown that obese people are more likely to suffer asthma than non-obese people, and also likely to suffer more severely.
The researchers asked patients about their weight, height, smoking habits, other illnesses, treatment and their asthma-specific quality of life, besides asthma control and asthma-related hospitalisations.
"Given that nearly 30 per cent of our country is obese, this study is yet another example of the long-term dangers of obesity, along with heart disease, diabetes, stroke and dementia," Mosen said.
"The take-home message of this study for clinicians is that obese people with asthma need to be followed more carefully because it's harder to control their asthma, so they are more likely to end up in the hospital," said co-author Michael Schatz.
