Children conceived via ART and born between January 1, 2004, and December 31, 2014, were identified as the exposure group. A control group of children conceived naturally was selected using 1:4 matching based on maternal age, neonatal sex, and birth month. Data analysis was performed from December 1, 2023, to November 1, 2025.<\/jats:p>\n <\/jats:sec>\n \n Exposure<\/jats:title>\n Conception via ART or naturally.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The primary outcome was development of atopic disease. Both groups were followed up until December 31, 2020. Cox proportional hazards regression models were used to adjust potential confounders.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 69\u202f785 children (13\u202f957 in the ART group and 55\u202f828 in the control group) were included in this study, with follow-up beginning at birth. The study population was 47.5% female and 52.5% male. For the ART and control groups, the mean (SD) follow-up duration was 7.99 (4.22) and 8.41 (4.18) years for asthma, 5.79 (4.12) and 6.34 (4.28) years for allergic rhinitis, and 7.34 (5.13) and 7.62 (5.14) years for atopic dermatitis, respectively. After adjusting for potential confounders, the ART group exhibited a higher likelihood of developing asthma (adjusted hazard ratio [AHR], 1.13 [95% CI, 1.09-1.18]), allergic rhinitis (AHR, 1.15 [95% CI, 1.12-1.18]), or atopic dermatitis (AHR, 1.08 [95% CI, 1.05-1.12]) (all\n P<\/jats:italic>\n \u2009&amp;lt;\u2009.001) compared with the control group. Subgroup analysis revealed that children conceived with fresh embryos faced a greater risk of developing allergic rhinitis compared with those conceived with frozen embryos (AHR, 1.12 [95% CI, 1.06-1.19];\n P<\/jats:italic>\n \u2009&amp;lt;\u2009.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n The findings of this cohort study suggest that children conceived via ART had a higher risk of developing asthma, allergic rhinitis, or atopic dermatitis. These findings underscore the importance of long-term follow-up for offspring conceived via ART and further investigation into the underlying biological mechanisms by which ART may contribute to atopic disease development.<\/jats:p>\n
