A critical appraisal checklist was utilised for scrutinising methodological quality of eligible studies. Meta-analysis was performed and heterogeneity was examined with the use of the Chi-squared test. This review was conducted based on a published protocol (www.crd.york.ac.uk/PROSPERO CRD42020148671).Results Meta-analysis showed that obese subjects are more likely to use asthma medications, including short-acting β2-agonists (OR 1.75, 95% CI 1.17–2.60; p=0.006, I2=41%) and maintenance oral corticosteroids (OR 1.86, 95% CI 1.49–2.31; p<0.001, I2=0%) compared to healthy-weight subjects. Inhaled corticosteroid (ICS) dose (µg·day−1) was significantly higher in obese subjects (mean difference 208.14, 95% CI 107.01–309.27; p<0.001, I2=74%). Forced expiratory volume in 1 s (FEV1) % predicted was significantly lower in obese subjects (mean difference −5.32%, 95% CI −6.75–−3.89; p<0.001, I2=42%); however, no significant differences were observed in FEV1/forced vital capacity (FVC) ratio between groups.Conclusions We found that obese subjects with asthma have higher use of all included asthma medication classes and higher ICS doses than healthy-weight asthma subjects, despite lower FEV1 and a similar FEV1/FVC %. A better understanding of the factors driving increased medication use is required to improve outcomes in this subgroup of asthmatics.Obese asthmatics have higher use of all included asthma medications and take higher ICS doses than healthy-weight subjects, despite similar FEV1/FVC %, emphasising the need for new, more effective management strategies to be developed for this population. https://bit.ly/2EQtPSi ER -
