Background: A country's developmental progress and overall changes in socio-economic structure are reflected in the outcome of secular trend studies on physical growth of children. The aim of this study was to compare anthropometric and biochemical indices of adolescent boys and girls born during and after the Iran-Iraq war.
Methods: Adolescents, aged 11 - 18 years, were selected from the TLGS cohort and divided into two groups. In the first group, adolescents born during the war and in the second group adolescents born after the war were included. Height, weight, serum lipids, FBS, systolic and diastolic blood pressure, and BMI were compared amongst adolescents of the same ages between the two groups.
Results: Mean weight and height increased at the ages of 12, 13, 14, and 17 years in boys of the post-war group. The mean weight of girls in the post-war group increased at the ages of 11, 13, and 14 years. Between 11 - 14 years, the means for total and LDL cholesterol, and between the ages of 15 - 18 years FBS, total cholesterol and LDL cholesterol decreased in boys of the post-war group. For girls between the ages of 11 - 14, FBS, total cholesterol, TG and LDL cholesterol, and between the ages of 15 - 18 years, FBS, total cholesterol and LDL cholesterol decreased in the post-war group. Systolic and diastolic blood pressure decreased at all ages in both groups.
Conclusion: This study showed that some anthropometric indices such as height and weight increased in boys who were born after the war; but in girls, the mean weight in the age groups increased. Systolic and diastolic blood pressure, and some lipid profiles decreased in boys and girls of the post-war group.
