Food diversity at 12\u2009months (six food groups) was categorized as low (0\u20132), moderate (3\u20134), or high (5\u20136). The primary outcome was incident AD, ascertained from the index date through the end of follow\u2010up based on \u22652 diagnostic claims and \u22652 topical corticosteroid prescriptions. We minimized reverse causation by strictly excluding infants with prior AD. Cox models were employed, adjusting for clinical covariates and, crucially, maternal allergic history due to its significant influence on infant feeding practices.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among the 267,935 eligible infants, 20,362 (7.6%) were in the low, 95,241 (35.5%) in the moderate, and 152,331 (56.8%) in the high diversity group. Compared with the high diversity group, both the low and moderate diversity groups showed a significantly increased risk of AD (adjusted hazard ratio [aHR] 1.08; 95% CI 1.04\u20131.12, and aHR 1.11; 95% CI 1.09\u20131.13, respectively). No significant interaction was observed by infant sex or maternal history of asthma or AD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Lower dietary diversity during the first year of life was associated with an increased risk of subsequent AD in this nationwide cohort.
