title: No association between previous Caesarean-section delivery and back pain in mid-aged Australian women: an observational study.
abstract: OBJECTIVE
  Is there an association between Caesarean section and back pain over the longer term?
  
  
  METHODS
  Secondary analysis of data from the Australian Longitudinal Study on Women's Health.
  
  
  METHODS
  The mid-aged cohort of women within the Australian Longitudinal Study on Women's Health aged 54 to 59 years (n = 9146).
  
  
  METHODS
  Data were included from women who answered the question regarding back pain. Data were extracted on whether they had given birth and, if so, whether it was by Caesarean section. Then, data on confounding variables (such as arthritis, asthma, osteoporosis, hysterectomy, ovaries removed, and repair of prolapsed vagina, bladder or bowel, menopause, smoking) were also extracted.
  
  
  RESULTS
  After adjusting for confounding factors, women who delivered by Caesarean section had the same odds (OR 1.03, 95% CI 0.81 to 1.31) of having back pain as women who had not had a birth.
  
  
  CONCLUSIONS
  Previous delivery by Caesarean section is not associated with increased back pain in mid-aged Australian women.
