Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) for child allergies were calculated using multivariable logistic regression analyses with reference to the lowest intake group.</p></div><div><h3>Results</h3><p>Levels of maternal intake of n-3 PUFAs or fish showed inverted associations (i.e., reduced risk) with the incidence of physician-diagnosed allergic rhinoconjunctivitis or parent-reported symptoms of current rhinitis with eye symptoms at different time points and the cumulative incidence from birth to 3 years of age. Inverted associations were also found for current wheeze at 1-&lt;2 years of age and current eczema at 1-&lt;2 and 0-&lt;3 years of age. However, for food allergies, no significant associations were observed in the incidence in each group compared with the lowest intake group at any age.</p></div><div><h3>Conclusions</h3><p>The findings suggest that n-3 PUFA intake during pregnancy may reduce the risk of developing allergic diseases and symptoms in children. In addition, consumption of n-3 PUFAs or fish is very unlikely to increase the risk of allergy given that the results are from a country with high fish consumption. <em>Trial registration</em>: UMIN000030786 <span>https://rctportal.niph.go.jp/detail/um?trial_id=UMIN000030786</span><svg><path></path></svg>.</p></div>","PeriodicalId":48861,"journal":{"name":"Allergology International","volume":"73 2","pages":"Pages 282-289"},"PeriodicalIF":6.8,"publicationDate":"2024-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1323893023001399/pdfft?md5=a8dfb91dcfe73f986ecbddd82c6cd71d&pid=1-s2.0-S1323893023001399-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139464561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
