Abstract:

The associations between the consumption of fast foods and asthma or allergic diseases have not been clarified. The aim of this study was to determine whether fast foods consumption is associated with asthma or allergic diseases. Databases were searched up to February 2018. Studies investigating the associations between fast foods consumption and asthma or allergic diseases were considered eligible. Included studies were assessed for quality using standardized critical appraisal checklists. The quality scores were 5.33 ± 1.16 in case-control studies and 5.69 ± 1.55 in cross-sectional studies. Adjusted odds ratios (aOR) with 95% confidence interval (CI) were pooled. Sixteen studies (13 cross-sectional and 3 case-control studies) were included. The consumption of fast foods was significantly related to current asthma (aOR: 1.58; 95% CI: 1.17-2.13 for case-control study and aOR: 1.58; 95% CI: 1.10-2.26 for cross-sectional studies), severe asthma (aOR: 1.34; 95% CI: 1.23-1.46), asthma ever (aOR: 1.36; 95% CI: 1.06-1.75), current wheeze (aOR: 1.21; 95% CI: 1.16-1.27), wheeze ever (aOR: 1.65; 95% CI: 1.07-2.52), physician-diagnosed allergic rhinitis (odds ratio: 1.43; 95% CI: 1.05-1.95), severe eczema (aOR: 1.51; 95% CI: 1.16-1.96) and severe rhino-conjunctivitis (aOR: 1.54; 95% CI: 1.18-2.00). The consumption of hamburgers was associated with current asthma (aOR: 1.59; 95% CI: 1.13-2.25), severeasthma (aOR: 1.34; 95% CI: 1.23-1.46), asthma ever (aOR: 1.47; 95% CI: 1.13-1.92), severe eczema (aOR: 1.51; 95% CI: 1.16-1.96), severe rhino-conjunctivitis (aOR: 1.54; 95% CI: 1.18-2.00) and rhino-conjunctivitis (aOR: 1.21; 95% CI: 1.15-1.27). The consumption of fast foods, especially hamburgers, ≥3 times/week, was more likely to be associated with severe asthma and current wheeze compared with the consumption of 1-2 times/week (both P < 0.001). In conclusion, the consumption of fast foods, particularly hamburgers, correlates to asthma in a dose-response pattern, which needs to be further validated in longitudinal and interventional studies.
