A postal questionnaire survey was carried out in Dutch agriculture to
identify high risk branches with respect to musculoskeletal symptoms a
nd workload. The study population comprised a sample 2580 male employe
es and employers, with a response rate of 49%. A total of 75% of the e
mployees and 71% of the employers reported musculoskeletal symptoms du
ring the past 12 months. Low-back pain was most prevalent (one-year pr
evalence rate of 51% among employees, 47% among employers), followed b
y symptoms of the neck-shoulder (one-year prevalence rate of 35% among
employees, 30% among employers) and knees (one-year prevalence rate o
f 22% among employees, 17% among employers). There were marked differe
nces between specific branches in the size and nature of musculoskelet
al morbidity as well as in self-reported musculoskeletal workload. In
particular protective vegetables growing and arboriculture showed both
relatively high rates of symptoms and relatively high exposure levels
. The results of this study were used to decide which agricultural bra
nches and workload factors should have priority in the ergonomic inter
ventions that followed.
