PURPOSE: It is known that children exposed to animals (dog, cat) may have increased respiratory symptoms in early life but such exposure as family pets may have a protective role in some against developing asthma. As prevalence of asthma is different in different ethnic populations, we hypothesized that differences in having pets at home may be one of the risk factor for differences in asthma prevalence in different ethnic populations.
METHODS: After local IRB approval, Pediatric Asthma Center was established at Nationwide Children’s Hospital in 2010 and since then we have seen 542 patients which were included in this study. Families at their first visit were given a questionnaire which included information on ethnicity and presence of pet at home.
RESULTS: Out of 542 patients, 317 (58%) were males and 225 (41.4%) were females. Mean age in years was 7 ± 4, mean age at diagnosis was 2.7 ± 2.4 and mean duration of symptoms was 4.5 ± 3.7 years. 358 (66%) were Caucasian, 116 (21.4%) were African Americans and 35 (6.4%) were Hispanic. Among 542 patients, 318 (60%) had pet at home and among them 247 (46.5%) had dog and 112 (21%) had cat at home and 75 (22%) had both cat and dog. Out of 351 Caucasians, 247 (70.4%) had a pet at home, while out of 115 African Americans (AA), 45 (39%) had a pet at home while out of 34 Hispanics 16 (47%) had a pet at home thus significantly more Caucasians (compared to AA, or Hispanics) had pet at home (p<0.001). For dog , out of 351 Caucasians, 194 (55%) had a dog at home, comapred to 35 (30%) out of 115 African Americans, and 13 (38%) out of 34 Hispanics thus significantly more Caucasians (compared to AA and hispanics) had dog at home (p<0.001). For cat out of 351 Caucasians, 95 (27%) had a cat at home, compared to 9 (8%) of 115 African Americans and 3 (9%) of 34 Hispanics thus significantly more Caucasians (compared to AA and hispanics) had cat at home (p<0.001 for both). For both cat and dog out of 351 Caucasians, 65 (18%) had both cats and dogs at home, while out of 115 African Americans, 7(6%) and out of 34 Hispanics 3 (9%) had both cat and dog at home. Significantly more Caucasians (compared to AA and hispanics) had both cat and dogs at home (p=003).
CONCLUSIONS: More caucasians had pets at home which may play a role in decreased asthma prevalence in this group comapred to african americans and hispanics.
CLINICAL IMPLICATIONS: Differences in having pet at home may be playing a role in variations in asthma prevalence in different ethnic groups
