Objective: Because of the necessity for more and different follow-ups in children with developmental disorders in the early years of life, determination of contributing, factors especially those related to pregnancy is important in any community. This study was performed to reveal a correlation of anemia in mothers during childbirth with developmental status of 12-month infants.

Materials & Methods: This study was performed through designing descriptive correlation on 250 mothers and their 12-month infants who visited to health services centers affiliated to Qazvin University of Medical Sciences and Health-Treatment Services in 1390 in multistage sampling method. Data collection tool included informational forms, Ages and Stages Questionnaire. Thereafter, the data was statistically analyzed with and Chi-square, Independent T, Mann-Whitney and Logistic regression tests.

Results: The prevalence of iron-deficiency anemia in the studied community was 12% and the prevalence of developmental delay of children was 22.4%. Anemia had a significant correlation with developmental status of infants and its communicational domain (P<0.05). In the logistics model, hemoglobin showed significant correlation with developmental status of infants (P=0.02 and OR=0.31). 66.7% out of all infants in anemic group and 55% in non-anemic group were male boys. Also the male gender had a ratio close to significance level (P=0.55 and OR=0.052). Other variables showed no correlations.

Conclusion: Mother’s Iran Deficiency anemia showed to be in possible attribution with infants’ Developmental delay and it is compatible with the crucial role of Iran for central nervous system development.
