title: Prevalence of low back pain among rice farmers in a rural community in Thailand.
abstract: OBJECTIVE
  To determine the prevalence of low back pain (LBP) among rice farmers in a rural community in Phitsanulok, Thailand.
  
  
  METHODS
  A cross-sectional survey was conducted among 283 rice farmers in Wangnamkhu subdistrict, Muang district, Phitsanulok province, a rural community in Lower Northern Thailand. Face-to-face interviews with a structured closed-end questionnaire were performed to collect information on the presence of LBP in lifetime, within the last 12 months prior to and at the time of the present study.
  
  
  RESULTS
  The lifetime, 1-year (12-month) and point prevalence rates of LBP were 77%, 56% and 49%, respectively. No relationship between age and LBP was found. However women (61%) had significantly greater 1-year prevalence than men (51%). Ninety-five percent of LBP rice farmers were chronic (experiencing pain longer than 12 weeks) with a mean duration of 292 weeks (5.6 years).
  
  
  CONCLUSIONS
  The prevalence of LBP among Thai rice farmers is high. Further research should investigate risk factors among this group of the population to design appropriate preventive measures.
