Systematic random sampling was used in selecting children who used backpacks. Starehe Sub –county was purposively selected for the study due to the diverse nature of the population in terms of socio-economic status (n = 248) Analysis. Data was analyzed through descriptive statistics, chi-square test of independence and logistic regression. Main outcome measures. Bag-use related musculoskeletal pain, socio demographic factors and ergonomic factors Results. Most of the participants (25.1 %) reported lower back pain while 16.9 % had neck pains.247 (65 %) were from the public primary schools while 132 (35 %) were drawn from private primary schools. There was almost equal representation from both gender, 194 (51.2 %) of the respondents were males and 185 (48.8 %) females. Majority, 279 (73.6 %) reported that they experienced pain when carrying school bag. There was no significant association between gender and pain (p>0.05). However, age and pupil’s weight were significantly associated with pain (p<0.05). Chi square test also indicated that factors such as backpack weight, rest breaks from carrying backpack, academic stress, method of backpack carriage, body posture on carriage were significantly associated with pain (p<0.05). Conclusion. Musculoskeletal pain was significantly associated with school bag weight, rest breaks from carrying bag, method of bag carriage and body posture on carriage. Recommendations. School management should encourage pupils to carry lighter backpack (<15 % of pupil’s body weight) and wearing bag on both shoulders.
