title: On the relationship between weight status and doctor shopping behavior-evidence from Australia.
abstract: OBJECTIVE
  A recent study has suggested that overweight and obese people are more likely to consult a range of physicians (doctor shopping). The consistency of this finding with multiple measures of doctor shopping and controls for socioeconomic circumstances was interrogated.
  
  
  METHODS
  Ninety-nine thousand four hundred seven Australians aged 45 and over who had sought primary healthcare at least five times within 6 months of a survey (2006-2008). (i) The count of different physicians consulted; a binary indicator of (ii) >= three different physicians; (iii) >= five different physicians; and iv) a measure that took into account multiple consultations with the same physician were investigated. Weight status was measured using Body Mass Index (BMI) based on self-reported height and weight. Controls included socioeconomic circumstances, demographics, health, and neighborhood factors.
  
  
  RESULTS
  In comparison to people with "normal" BMI, the likelihood of doctor shopping was lower among overweight (Incidence Rate Ratio: 0.97, 95%CI: 0.96, 0.98) and obese people (0.95: 0.93, 0.96). This negative correlation between doctor shopping behavior and weight status was consistent after full adjustment and across different outcome measures.
  
  
  CONCLUSIONS
  In contrast with recent evidence from the US, overweight and obese Australians are less prone to doctor shopping behavior than their peers with "normal" BMI.
