Belly fat, linked with diabetes and heart disease, and could also have a bearing on the development of asthma, research in Norway shows. Previous studies have found a link between asthma and body mass index (BMI), a height to weight ratio that is an indicator of overall obesity.
Researchers followed 23,245 adults without asthma, aged 19-55 years for 11 years, according to a statement of Norwegian University of Science and Technology. The participants had their BMI measured along with their waist circumference to test overall obesity and central obesity. Besides, they were also asked to report incidence of asthma. The results showed that people who had belly fat but were not overall obese were 1.44 times more likely to develop asthma. Additionally, people who were both centrally obese (belly fat) and obese overall were 1.81 times more susceptible.
Asthma can affect people of all sizes, but study has highlighted both the individual and combined effect of central obesity and overall obesity on asthma development.
