Having teachers from both primary and high schools together with different working conditions and demands
might be a source of heterogeneity in study sample.
Therefore, homogeneity of study population should becarefully considered in future studies.
Although this study investigated the association between the prevalence of LBPand some risk factors such as age, BMI, general health,years of teaching, and others, further study with larger and more homogenous sample is needed to confirm these associations.
Also, future research with cohort or randomized controlled clinical trial designs should focus on the evaluation of different preventive strategies with a greater emphasis on monitoring the risk factors as well as evaluating the effect of ergonomic factors to reduce the impact of such a major health concern in teachers.
