Abstract:

Objective: To assess the Backpack load and comparison of ventilatory function with and without backpack in school children. Methodology: This analytical cross sectional study was conducted in government and private schools of Islamabad & Rawalpindi, Pakistan from June to August 2019. Sampling technique employed was non-probability convenience sampling. Spirometry readings were taken with and without backpack. Results: Out of 382 children, 96 (28.1%) were boys and 286 (74.9%) girls. The mean age was 9.86±0.9 years. The mean weight of bag was 6.46±1.23 kg, whereas the mean weight of backpack as %age of body weight was 21.41±4.86%. There was a statistically significant difference in FVC and PEF with and without carrying backpack (p<0.05). Conclusion: There was significant reduction in pulmonary function parameters (FVC & PEF) after wearing the loaded backpack. Thus, backpack limit guidelines should be practically implemented for ensuring children's health and safety.
