Eating Disorders

Number of patients consulting

The graph below shows the estimated number of patients in Scotland per 1,000 patients registered with a practice who consulted either a GP or practice-employed nurse for eating disorders at least once in the year ending 31 March 2010, by gender and age group. Included in the definition of eating disorders are anorexia nervosa, bulimia and other less common eating disorders. Figures are standardised by deprivation to the Scottish population to account for any differences between the PTI sample population and the Scottish practice population in levels of deprivation.

The graph confirms that eating disorders are a particular issue in 15 to 24 year old females. Numbers of consultations for older patients are much lower and are therefore are not shown subdivided into finer age categories.

These figures and comparable figures for 2003/04 to 2008/09 are also provided in tabular format in an Excel document link to a microsoft excel file (80KB), which also contains 95% confidence intervals for all estimates. The Excel table shows a total estimate of around 4,400 patients seen in the most recent year for eating disorders, with a 95% confidence interval between 3,100 and 5,600 patients. Eating disorders are not recorded very frequently as reason for consultation so the estimates are based on low numbers of patients and there is sometimes substantial variation between individual practices in the numbers reported. This is reflected in fairly wide confidence intervals, which means that these estimates have limited precision.  This should be kept in mind when interpreting these figures.

Note: PTI aims to continually improve the interpretation of the data and therefore analysis methods are regularly reviewed and sometimes updated. The minor changes made for the publication of 22 February 2011 have a minimal impact on estimated numbers of patients; however these make the figures given in this current publication not strictly comparable to those provided prior to 22nd February 2011.  See the Note of Revisions for further information.

Number of consultations

The chart below shows the estimated numbers of consultations in Scotland for eating disorders for the seven financial years 2003/04 to 2009/10, by staff discipline. All estimates are standardised to the Scottish population by age, sex and deprivation to account for any differences in these characteristics between the PTI sample population and the Scottish practice population. These figures are provided in tabular format in an Excel document link to a microsoft excel file (22KB), which includes 95% confidence intervals for all estimates.

The chart shows that most of the consultations for eating disorders were with GPs, with a generally much smaller estimated number for practice nurses. There was no clear pattern in the number of consultations for eating disorders over the seven years although estimates for 2009/10 seem to be the highest so far, but given the large confidence intervals the differences between the years should not be considered significant.

2 Based on 59, 53, 51, 49, 48, 58 and 60 PTI practices that submitted complete data for the years ending 31 March 2004 to 2010, respectively. Figures are standardised by age, gender and deprivation.
3 Population source: Community Health Index (CHI) record, as at 30 September 2003 to 2009.

Note: PTI aims to continually improve the interpretation of the data and therefore analysis methods are regularly reviewed and sometimes updated.  The rules for dealing with duplication in practice-employed nurse data were expanded for the publication of 22 February 2011 and applied to all new and historic data.  This has resulted in slightly lower estimated numbers of consultations for practice nurses than published previously, particularly for the earlier years shown above. Therefore figures shown here are not strictly comparable to these published previously. See the Note of Revisions for further information.
