en public specific orginal article <strong>Background: </strong>Due to the importance of nutrition during pregnancy and its role in future generations&#39; health, the study tried to determine dietary diversity and its relationship with newborns&#39; anthropometric indices at birth. <strong>Methods: </strong>In this cross-sectional study, 400 pregnant women (28-40 weeks of pregnancy) whom were referred to the health centers in Zahedan were studied in 2016. To assess the usual dietary intake, food frequency questionnaire and the 24-hour recall were used. Dietary diversity was calculated based on the score 8 of food groups using food pyramid of Food and Agriculture Department, and Kant method. Newborns&#39; anthropometric indices were measured by the standard and analyzed by using descriptive statistics and analytical tests. <strong>Results: </strong>The mean (&plusmn; Standard deviation) of the total score of dietary diversity was 2.60 &plusmn; 0.73 and the highest diversity was seen in the dairy group (0.45 &plusmn; 0.19) and the lowest diversity of food was observed in grains group (0.20 &plusmn; 0.10). There was a significant difference between various groups of birth weight at the score of dietary diversity and it was significantly increased by rising family&#39;s incomes. The linear regression analysis has shown that the variables including; weight at the beginning of pregnancy, a variety of dairy products, vegetables and total dietary diversity could be considered for predicting birth weight. <strong>Conclusion:</strong> The study has shown that there was a significant correlation between the score of dietary diversity and newborns&#39; anthropometric indices at birth Birth weight, Dietary diversity, Pregnancy 116 122 http://jnfs.ssu.ac.ir/browse.php?a_code=A-10-1-89&slc_lang=en&sid=1 Atena Jamalzehi Yes Department of Nutrition, School of Public Health, Qazvin University of Medical Sciences, Qazvin, Iran Maryam Javadi No Department of Nutrition, School of Public Health, Qazvin University of Medical Sciences, Qazvin, Iran Alireza Dashipour No Department of Nutrition and Food Science, School of Medicine, Zahedan University of Medical Sciences, Zahedan, Iran
