Actual (reported)A large study in Mallorca, Spain showed that nonspecific low back pain is quite prevalent in adolescents 13-15 years of age (Kovacs, 2003). Since below the age of seven years hardly any child has suffered low back pain, the purpose of this study is to determine the prevalence of low back pain in children 10-12 years of age, and to investigate the risk factors associated with its occurrence.
