Vitamin D and weight loss useful in asthma patients , reports new study

A new study has reported that both obese and non-obese patients suffering from asthma have a reduced Vitamin D intake. The study was published in the journal Endocrine, Metabolic & Immune Disorders – Drug Targets.

Occupational asthma is a common occurrence in a significant number of adults suffering from the disease. Even after the cessation of exposure, asthma remains dominant.

The researchers conducted a study to assess the Vitamin D intake in occupational asthma patients and its relation to body mass index, co-morbidities related to Vitamin D deficit, lung function and quality of life.

Previously, Vitamin D intake was rarely evaluated in cases of occupational asthma regardless of it being an important part of nutrition.

The researchers found a reduced Vitamin D intake in both irritant and allergic asthma both in obese and non-obese patients. Even though the average intake levels were comparably higher in non-obese patients than obese patients, it did not reach a significant level.

Lower intake was also found in mild asthma group compared to severe asthma group, marginally reaching significance level at the median test. Regression analysis revealed a different pattern in the asthma groups. The Impact score in irritant asthma indicated a stronger relationship with BMI while the symptom score in allergic asthma group was closely associated with the Vitamin D intake.

The researchers concluded that the relationship between obesity and vitamin D on clinical scores and lung function depended on the asthma phenotype. It was recommended that the nutritional interventions in all occupational asthma phenotypes should be an important aspect in future treatments, especially targeting body fat reduction and achievement of the daily recommended intake of Vitamin D. When studying the impact of weight loss on asthma progression, it was concluded that Vitamin D status should be taken as an influence.

“However, our study supports the usefulness of nutritional interventions in all occupational asthma patients, targeting both the reduction of the fat mass and the achievement of the recommended daily intake of vitamin D. When analyzing the impact of the weight loss effect on asthma evolution, the vitamin D status should also be considered as an influencer” write the authors.
