| Summary: | Introduction: The objective of the present study was to investigate the effect of lying on the stomach on the spine angles of 13-18-year-old students in Karaj.Martials and Methods: This study was quasi-experimental and comparative conducted by field method. For this purpose, 105 13-18-year-old students of girls' schools in District 3 of Karaj during the academic year 2020-2021, who were accustomed to lying on the stomachs, randomly participated in the study by convenience sampling method and based on the number of study hours per day, less than 1 h, between 1 and 2 h and more than 2 h placed in three groups. Research variables including angles of forward head, unequal shoulder, lumbar lordosis, dorsal kyphosis and scoliosis were assessed using standard tests with high validity and reliability. The data were analyzed using one-way analysis of variance and Bonferroni post hoc test at the significance level of 0.05.Results: A significant difference was between lumbar lordosis and forward head angle abnormalities among students who were less than 1 h and more than 2 h accustomed to lying on their stomachs (P<0.05). But this difference was not significant for variables of uneven (dropped) shoulder, dorsal kyphosis and scoliosis (P<0.05). The students who studied for more than 2 h a day while lying on their stomachs had abnormalities of lumbar lordosis and forward head angle.Conclusion: Lumbar and prefrontal lordosis abnormalities are common in students who study lying on their stomachs and repeat the condition for at least 2 h a day. |
