Asthma is one of the principal causes of absenteeism from school and the leading cause of emergency department visits for children in the United States. Some dietary habits are associated with asthma prevalence and play a role in the pathogenesis and control of symptoms. The objective of this study was to characterize dietary factors that may affect asthma outcomes among children with asthma in California. The California Health Interview Survey (CHIS) is the largest state health survey in the nation. This cross-sectional study included 7687 surveys, representing an estimated annual 710,534 children (ages 2–11) reported to have asthma between 2001 and 2015. Analysis was survey-weighted. We used multivariable regression, adjusting for covariates, to examine the association between dietary factors and asthma outcomes. Asthmatic children consuming two or more servings of sodas per day had more symptoms of asthma than those who did not consume soda daily (OR = 1.50, 95% CI: 1.04, 2.15). Moreover, those consuming two servings of fruits per day had lower odds of missing school due to asthma. Children with asthma may be affected by certain pro-inflammatory foods that are energy dense. This study provided an additional reason to discourage the consumption of sodas and sugary drinks due to the negative respiratory impact, in addition to their effect on childhood obesity, oral health problems, and future chronic diseases.
