title: How common is back pain in Al-Qaseem region.
abstract: OBJECTIVE
  The aim of this study was to estimate the prevalence of back pain in the adult population of Al-Qaseem Central Province, Kingdom of Saudi Arabia and to find associated features and factors.
  
  
  METHODS
  A house-to-house survey covering 1,000 household in the towns and villages of Al-Qaseem province was carried out over a period of 18 months extending from September 1993 until the end of February 1995. A total of 5,894 adults, aged 16 years and above, were questioned by trained staff regarding back pain, and the demographic data in addition to general, medical and social history.
  
  
  RESULTS
  A response was obtained in 5,743 (97.4%). Their mean age was 34.14   15.16 (range 16-99). Back pain was reported by 1,081 (18.8%), wherein 499 (8.8%) were men, and 574 (10%) were women. Back pain was more prevalent in married (23.3%) individuals than unmarried (6.4%). Adjusted odds ratio (OR) for back pain in married individuals was 1.88 (95% confidence intervals [CI] 1.49-2.37). Back pain was strongly correlated with age (correlation coefficient = 0.378 P < 0.01). It also showed significant correlation with weight and height, depression, family history of back pain, change in work ability, frequency of attendance at local doctor, use of medication and lower education level. The association with body mass index became evident only after comparing the heaviest 20th percentile to the lightest (OR 1.335 [95% CI, 1.279-1.402]). Certain occupational status (unemployed, farmers, professional workers and housewives) were associated with back pain.
  
  
  CONCLUSIONS
  Back pain was relatively common in this largely unindustrialized community although its prevalence is lower than reported from some western countries.
