Objectives To find risk factors for back pain in retrospective study, one year follow-up study, recurrence and first episode of back pain in one year follow-up study in nurses.
Methods The study was performed on 470 nurses of clinical hospital, 92,3% of nurses answered a questionnaire concerning information about low back pain. 358 (82,5%) have answered the questionnaire on the physical activities performed at work and 369 (85,0%) were examined. 87,9% of nurses who answered the first questionnaire have taken part in follow up study. The potential relationship of the investigated 47 variables like financial status, habits, physical activity or work conditions were assessed in multivariate logistic regression model and then the role of significant variables was counted as relative risk with 95% of confidence interval in univariate logistic regression model. For statistical evaluation of the data STATA 5.0 software was used.
Results The multivariate logistic regression analysis did not show any common risk factor for back pain in cross sectional, one-year follow up study, for the first episode or for the reoccurrence of back pain in one-year follow up study. Cycling was a risk factor for back pain in both one year follow-up study and first episode (OR 1,3) and for recurrence of back pain (OR 1,9) and the same applied to work with arms elevated on the shoulder level longer than 1 min an hour. These two variables were the only significant risk factors (p < 0,05) for the first episode of back pain in one-year follow up study. Spinal mobility ranges in different planes did not have any impact on first episode of back pain. Age, bringing up children, alcohol drinking, experiencing recurrent diarrheas, abdominal pain, discontentment with own job, limited lateral trunk flexion to the right, pushing heavy objects and both hands lifting weights were risk factors only for reoccurrence of back pain in a one-year follow up study. Bad assessment of the own health was a risk factor of back pain in cross sectional, one-year follow up study and especially for the reoccurrence of back pain in one-year follow up study.
Conclusion There are different risk factors of back pain in retrospective study, one year follow-up study, recurrence and first episode of back pain in one year follow-up study in nurses.
