title: Sociodemographic factors associated with calcium intake in premenopausal women: a cross-sectional study.
abstract: OBJECTIVE
  To describe associations between sociodemographic factors and calcium intake in premenopausal women.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  Population-based.
  
  
  METHODS
  A total of 467 randomly selected, predominantly Caucasian Tasmanian women aged 25-44 y, response rate 63%.
  
  
  METHODS
  calcium intake, sociodemographic factors, anthropometrics, osteoporosis knowledge and self-efficacy.
  
  
  RESULTS
  Education level, calcium-specific osteoporosis knowledge and self-efficacy were all independently associated with calcium intake (P<0.05). The odds of achieving the recommended dietary intake for calcium increased with higher levels of calcium-specific self-efficacy and knowledge, and decreased in smokers or if the household's main financial provider was unemployed (P<0.05).
  
  
  CONCLUSIONS
  Women who have lower levels of education, who are in households where the main financial provider is unemployed, who are smokers, and those with low levels of calcium-specific self-efficacy and knowledge are at risk of not achieving adequate calcium intake. This information will assist targeting of public health strategies aimed at improving the calcium intake of premenopausal women.
