Abstract

Background and Objectives: Using the anthropometric indicators of children is one of the ways of monitoring their growth. Because of the racial divisions and levels of health and welfare, comparing these indicators with the global reference is not reasonable; therefore, designing a local reference seems necessary. This study aimed to evaluate the growth indices for boys and girls aged 5 to 18 years old living in Isfahan and to compare the indices with standard values. Methods: In this cross-sectional study, 53,839 subjects were included. Percentiles of body mass index, height, and weight were calculated using the LMS method in the LMS Light software. After normalization of the growth indices, their mean and standard deviation were calculated for each age group and anthropometric indices curves were plotted versus the 5th, 50th and 95th percentiles of the NCHS reference. Results: In all age categories, the mean SDS scores of BMI in boys and girls was -0.004 ± 0.029 and 0.014 ± 0.062, respectively, indicating no difference with reference values. However, the 95th percentile of the body mass index for the reference population was consistent with the 90th percentile for the population studied. Also, weight in boys below 13 years of age was higher than the reference line while in girls, weight was always higher than the reference value. Conclusion: Due to differences in the pattern of growth and also lower anthropometric values, particularly among boys, it seems that a national growth curve can be a better guide for future decisions. © 2017, Iranian Epidemiological Association.
