Objectives Birth season has been inconsistently associated with anthropometrics, bone fractures, and malocclusion. Our aim was to assess the association between birth season and anthropometrics (height, weight, birth weight), bone fractures and dental malocclusion in the United States. Methods US surveys conducted between 1963‐1973 assessed 16 152 6‐to‐21‐year‐old participants. Prevalence ratios and mean differences were estimated using linear models using fall as reference. Results Participants born in spring, when compared to fall, were of similar height (mean difference (MD) in height‐adjusted Z score 0.03, 95% Confidence Interval (CI): −0.01 to 0.08; P ‐value = .17), weight (MD for weight‐adjusted Z‐score 0.00, 95% CI: −0.05 to 0.04; P‐value =0.83), had similar rates of bone fractures (Prevalence Rate [PR] 1.07; 95% CI: 0.94 to 1.22; P ‐value = .28) and similar rates of dental malocclusion (MD of malocclusion index HLD −0.16; 95% confidence interval − 0.39 to 0.07; P = .18). Conclusion We did not find an impact of birth season on anthropometrics, bone fractures, and dental malocclusions.
