Adults with asthma are more likely to be obese, according to a new study.

 

Adults with asthma are more likely to become obese later in life, especially those who have had the condition for longer or who are treated with corticosteroids, according to a research published Wednesday in Europe and Australia.

Here's another article on Vitamin B12 insufficiency: There are five'mood changes' that indicate that a deficit has progressed.

According to studies published in the journal Thorax, 17 percent of asthmatic participants from 11 European nations and Australia acquired obesity or were significantly overweight.

According to the study, slightly under 15% of individuals without asthma got fat.

According to the researchers, those with asthma in the study had a 21% greater risk of obesity than those who did not have the respiratory ailment.

They found that asthmatics on corticosteroid medicines had a roughly doubled incidence of obesity.

"A possible reason for the weight increase linked with asthma might be a decline in physical activity in asthmatic patients," research co-author Judith Garcia-Aymerich stated in a news statement. "However, our data do not support this theory."

Physical activity levels among research participants had no effect on their risk of obesity, she added, regardless of whether or not they had asthma.

"Regardless of the causes, which are yet unclear, our findings have consequences for the clinical management of individuals with asthma," said Garcia-Aymerich, the director of the Barcelona Institute for Global Health's non-communicable illnesses and environment programme.

According to study, lung disorders such as asthma and chronic obstructive pulmonary disorder, or COPD, have grown increasingly widespread internationally as a result of increased airborne pollution, among other things.

COPD has been associated to an increased risk of obesity in adults, and asthma has been connected to an increased risk of obesity in children in previous research. According to the Centers for Disease Control and Prevention, over 40 percent of adults and 19 percent of children in the United States are obese, while about 8% of adults and children in the country have asthma.

The researchers utilised data from the European Community Respiratory Health Survey cohort study, which is a continuous evaluation of population health financed by the European Commission.

Australia, Belgium, Estonia, France, Germany, Iceland, Italy, Norway, Spain, Sweden, Switzerland, and the United Kingdom participated in the research.

According to the researchers, participants completed lifestyle questionnaires, had lung function tests, and were examined for body weight and asthma status.

Participants with asthma who had the condition for a longer length of time had a 32 percent greater risk of obesity than those who had the respiratory ailment for a shorter period of time, according to the findings.

According to the researchers, people with non-allergic asthma, or asthma symptoms unrelated to allergens, had a 47 percent greater risk of obesity than those with allergic asthma.

In a news statement, research co-author Subhabrata Moitra noted, "Several studies have demonstrated that asthma and obesity have certain overlapping socioeconomic, behavioural, and environmental risk factors that might contribute to the development of both illnesses."

"Some previous research focused on the mechanisms by which obesity can lead to asthma, but the inverse relationship had not received much attention until recently," said Moitra, who is now a post-doctoral research fellow at the University of Alberta in Canada after previously working at the Barcelona Institute for Global Health.
