We investigated whether there is an increased risk of coronary heart diseases (CHD) in those with common allergic symptoms using the NHANES III, which is a representative sample of the United States population in 1988 to 1994. CHD was defined by Rose questionnaire and history of heart attack. Allergic symptoms were categorized into no symptoms (NO), rhinoconjunctivitis without wheezing (RC), and wheezing (WZ) based on symptoms. Multivariate logistic regression was used to obtain odds ratios (ORs) of CHD. Eight thousand six hundred fifty-three nonpregnant subjects <20 years old with overnight fasting <8 hours were included. CHD was present in 5.9% of the population; 36.5% did not have allergic symptoms (NO), 45.9% had RC, and 17.6% had WZ. The prevalence of CHD was 3.9% in NO, 4.8% in RC, and 12.8% in WZ (p <0.001). Compared to NO, unadjusted ORs of CHD were 1.24 (95% confidence interval 0.94 to 1.62) in RC and 3.58 (2.68 to 4.78) in WZ and ORs adjusted for sociodemographic factors and co-morbidities were 1.40 (1.02 to 1.92) in RC and 2.64 (1.79 to 3.90) in WZ. Only the group of women <50 years of age had significantly increased ORs in RC and WZ. In conclusion, common allergic symptoms were significantly associated with an increased risk of CHD.
