ABSTRACT
OBJECTIVES:
To determine if agricultural work is related to radiological flattening of lumbar lordosis, and to identify the relationship between of back pain and flat back in selected Korean farmers.METHODS:
Between June 2006 and July 2008, 414 farmers, 155 (37.4%) males and 259 (62.6%) females participated in this study. We collected data on hazardous agricultural work postures and other factors from interviews, surveys, and x-ray views of lateral lumbar. The operational definition of a flat back was below -1 SD of lordotic angle, with a normal distribution between L1 and S1 level. Logistic regression analysis was conducted to evaluate the relationship between flat back and hazardous working posture ratio, sex, the severity of back pain.RESULTS:
Mean lordotic angle was 42.9+/-15.7degrees. Flat back had a higher prevalence in the females (24.7%) than the males (5.8%). The odds ratio of flat back risk is 3.30 (95% CI 1.46~7.46) in the females compared to the males, 1.31 (95% CI 0.61~2.79), 4.11 (95% CI 1.77~9.55) in the group of hazardous working posture ratio compared to the low risk group, 2.78 (95% CI 1.27~6.07), 5.74 (95% CI 2.27~14.49) in the group of L4-L5 disc space narrowing compared to normal group, 3.06 (95% CI 1.27~7.31), 5.45 (95% CI 1.70~17.46) in the group of lumbar spine compression fracture compared to no fracture. Odds ratio of severe back pain is 2.29 (95% CI 1.12~4.72) in the group of flat back compared to normal group.CONCLUSIONS:
Hazardous agricultural working postures, such as 'low- lifting, pulling, pushing work and high- squatting posture work' are associated with flat back. Low back pain is significantly associated with flat back group in female farmers.
