Risk factors associated with back pain in New Zealand school children

This study investigated risk factors associated with back pain in 245 New Zealand intermediate school children aged 11-14 years in a cross-sectional survey, using a self-completion questionnaire for demographic details, pain prevalence, psychosocial parameters, school and leisure activities and family characteristics. The strongest relationships were between back pain and common childhood complaints (stomach ache, headache and sore throats) (p < 0.01) and psychosocial factors (conduct and hyperactivity) (p < 0.01). For physical factors, there was a significant relationship between neck and low back pain and attributes of chairs. Low back pain was significantly related to low desk height (as reported by students) (p < 0.05). School bag weight was not significantly related to low back pain but carrying the bag on one shoulder was (p < 0.05). It is concluded that, amongst these intermediate school children, psychological, social and emotional factors had a stronger relationship with back pain than physical factors. STATEMENT OF RELEVANCE: This study investigated risk factors associated with back pain amongst New Zealand intermediate school children. It showed that psychological, social and emotional factors may have a stronger relationship with back pain than physical factors.
