  1. Please acknowledge the National Obesity Observatory as well as the data source (e.g. Health Survey for England) when using any of these slides.The images on each slide are ‘grouped’; to copy the chart/graphic out of the slide right click and ‘ungroup’ the images.For more information on the data and information included please contact NOO: ncmp@noo.org.uk
  2. The published Health Survey for England data used to produce this graphic are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  3. The rise in obesity prevalence appears to be slowing for both sexes.Obesity prevalence remains higher for women, but the gap between men and women appears to have narrowed over time.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  4. The rise in excess weight (overweight including obese) prevalence appears have slowed for both sexes.Unlike for obesity prevalence, prevalence of excess weight is higher for men than women.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  5. Healthy weight prevalence is much lower for men than for women (even though obesity prevalence is marginally higher for women than for men). This is because there is a much higher prevalence of overweight in men than in women.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  6. This chart shows a trend of increasing prevalence of both men and women with a BMI ≥40kg/m2.Obesity III prevalence is much higher for women.http://www.noo.org.uk/NOO_about_obesity/Morbid_obesityThe published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  7. This chart shows the difference in the distribution of BMI between men and women. A greater proportion of women than men have a BMI less than 25 kg/m2 – i.e. underweight or healthy weight. A greater proportion of men than women have a BMI above 25 kg/m2 and less than 35 kg/m2 - i.e. overweight or the lower end of obese.A BMI of greater than 35 kg/m2 (i.e. the higher end of obese or morbidly obese) is more common among women than men.This distribution is based on adults aged 18+ years, whereas most published HSE figures for adults cover the age range 16+. This is because the distribution of adult BMI is substantially distorted by the inclusion of young adults aged 16 – 17 years, whose BMI distribution is very different to the rest of the adult population.The analysis for this chart was produced using Health Survey for England data from the UK Data Archive,http://www.data-archive.ac.uk/. This chart will be updated in summer 2013 when the row level 2011 HSE data are available.
  8. This chart shows the change in the BMI distribution among men and women aged 18 and over, using HSE data.Young adults aged 16 and 17 have not been included in this analysis, as the BMI distribution of people of this age is substantially different to that of the rest of the adult population.The data have been weighted to the English population at the time of measurement (i.e. 1991-1993 and 2008-2010). This means the distributions shown represent the BMI distribution within the adult population at that time.There have been minor changes in the age structure of the English population between 1991-93 and 2008-10, which could account for some of the differences between the BMI distributions shown for earlier years and the present day. However further analysis has shown that these changes account for only a very small proportion of the differences observed. The changes in the shape of the distribution since 1991-93 are therefore primarily due to increases in BMI rather than changes in the age structure.The analysis for this chart was produced using Health Survey for England data from the UK Data Archive,http://www.data-archive.ac.uk/. This chart will be updated in summer 2013 when the row level 2011 HSE data are available.
  9. There are differences in obesity prevalence by both age and sex.Obesity prevalence appears to increase with age in the age range 16 to 74 years, but then decreases above age 75 years. When broken down by age group, differences in obesity prevalence by sex are most noticeable in the 16-24 years and 75+ age groups. Here obesity prevalence is higher for women than for men. However between the ages of 45 and 64 years obesity prevalence appears to be higher among men than women. The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  10. The relationship between obesity prevalence and socioeconomic status differs by sex. Obesity prevalence among women tends to show a marked decrease as socioeconomic status improves, as shown above using equivalised household income. This pattern appears to be consistent across a number of indicators of socioeconomic status.The pattern is different for men. There is no apparent relationship between equivalised household income and obesity prevalence. However this relationship seems to vary between different indicators of socioeconomic status.More information and analysis is available in the Adult Obesity and Socioeconomic Status data factsheet, available to download at http://www.noo.org.uk/NOO_pub/Key_dataThe analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/.

  13. The chart shows variation in prevalence of obesity by ethnic group and between sexes within ethnic groups. Prevalence of obesity is higher in women compared to men for Black African and Pakistani ethnic groups. Prevalence of obesity is higher among women of Black Caribbean and Black African ethnicities, compared to the other ethnic groups.The data have been age standardised to adjust for the different average age by ethnic group.In order to produce analysis as similar as possible to published HSE data the following ethnic groups have been combined:Mixed White and Black Caribbean combined with Black CaribbeanMixed White and Black African combined with Black AfricanAny other white background combined with WhiteThe analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/.
  14. The 2004 Health Survey for England (HSE) included a boost sample of people from minority ethnic groups. The larger sample size enables more detailed analysis to be performed on smaller subsets of the population of England. The chart shows variation in prevalence of obesity by ethnic group and between sexes within ethnic groups. Prevalence of obesity is higher in women compared to men for Black African, Pakistani, and Bangladeshi ethnic groups. Prevalence of obesity is higher among women of Black Caribbean and Black African ethnicities, compared to the other ethnic groups.This may not match exactly to the published HSE figures for 2004. We have produced this chart to enable better (but not perfect) comparison with the 2006-2010 data shown on the previous slide. The data have been age standardised to adjust for the different average age by ethnic group.The pattern of obesity prevalence by ethnic group seems to have remained the same between 2004 and 2006-2010. The only difference of note is a possible increase in obesity prevalence among Bangladeshi men, however this is not statistically significant.In order to produce analysis as similar as possible to published HSE data the following ethnic groups have been combined:Mixed White and Black Caribbean combined with Black CaribbeanMixed White and Black African combined with Black AfricanAny other white background combined with WhiteThe analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/
  15. The trend in obesity prevalence by social class differs by sex. For all social classes prevalence of obesity among men has increased between 1994 and 2009; men from the skilled manual class consistently have the highest obesity prevalence and professional men the lowest prevalence. Women from the professional social class have the lowest prevalence of obesity. The apparent dip in prevalence in this group between 2001 and 2006 could be explained by the small sample size of women in this group during that period. There appear to be larger differences in prevalence in women between social class groups compared to men. Women in the unskilled manual class consistently have the highest prevalence of obesity.Social class of the survey respondent was not available in the 2010 HSE data, so this chart has not been updated.The analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/
  16. The prevalence of raised waist circumference is higher among women than men. Both sexes have seen an increase since 1993.For more information on waist circumference and other measures of central adiposity see:http://www.noo.org.uk/uploads/doc/vid_8864_MEASURES%20OF%20CENTRAL%20ADIPOSITY%20AS%20AN%20INDICATOR%20OF%20OBESITY%20August%2009_updated%20Dec%202010_.pdfThe published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  17. The prevalence of raised waist circumference increases with age for both men and women. There is a greater prevalence of raised waist circumference among women, particularly in the older age groups.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  18. Increasing proportions of both men and women have raised waist circumference (defined as &gt;102cm for men and &gt;88cm for women), as can be seen in the trend from 1993 to 2011.Waist circumference was not collected for the whole HSE sample in 1995, 1996, 1999, 2000, or 2004.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  19. Both raised BMI and raised waist circumference are thought to be independent predictors of future obesity related ill heath. Both NICE and the WHO have recommended the use of combined BMI and waist circumference categories for identifying an individual’s risk of obesity related ill health.This table shows how such categories can be used.Adapted from:National Institute of Health and Clinical Excellence. Obesity: the prevention, identification, assessment and management of overweight and obesity in adults and children. http://www.nice.org.uk/guidance/CG43 (accessed 18/02/2011)
  20. This figure shows the change in the England population’s risk of future obesity related ill health between 1993 and 2011. Using the combined BMI and waist circumference categories. There has been a steady increase in the proportion of adults with an increased, high, and very high risk of obesity related ill-health between 1993 and 2011.Waist circumference was not collected for the whole HSE sample in 1995, 1996, 1999, 2000, or 2004.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  21. This figure shows the change in the England population’s risk of future obesity related ill-health between 1993-94 and 2008-09. Using the combined BMI and waist circumference categories, over 10% more (in absolute terms) of the adult population are now at increased risk of obesity related ill-health than in 1993-94.In both 1993-1994 and 2008-2009 men and women have similar proportions at‘no increased risk’ and therefore also have similar proportions at ‘increased, high, and very high risk’, this is interesting as there are some differences in the prevalence of overweight and obesity by sex.The considerable increase in prevalence in the ‘very high risk’ category is the main contributor to this rise, for both men and women.The published Health Survey for England data used to produce this chart are available from:http://www.ic.nhs.uk/catalogue/PUB09302
  22. The proportion of adults at high or very high risk of obesity related ill-health increases with age for both men and women and falls slightly again in adults aged 75 and over.The analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/
  23. This figure shows the risk of future obesity-related ill health by ethnic group using the combined BMI and waist circumference (WC) categories.There is continuing debate about the applicability of definitions of obesity across ethnic groups. However, as there are no globally applicable BMI orWC thresholds as yet, NICE does not recommend separate BMI and WC thresholds for different ethnic groups in the UK.See the Obesity and Ethnicity briefing paper published by NOO for more information:http://www.noo.org.uk/uploads/doc/vid_9851_Obesity_ethnicity.pdfThe analysis for this chart was produced using Health Survey for England data from the UK Data Archive:http://www.data-archive.ac.uk/
  24. The HSE can provide relatively robust estimates of obesity prevalence at regional level. However, due to the relatively small sample size of the HSE, such estimates cannot be produced for smaller geographies using HSE data alone. In order to provide an estimation of obesity prevalence at sub-regional level the National Centre for Social Research (NatCen) have produced modelled estimates of adult obesity prevalence by local authority for 2006-2008.The modelled estimates provide an estimate of the expected level of obesity prevalence for each local authority based on the characteristics of the local population.This map is presented in a PDF poster available to download from the NOO website http://www.noo.org.uk/visualisation. This indicator is included in the adult e-atlas (see next slide for more information). http://www.noo.org.uk/visualisation/eatlas.
  25. The adult e-atlas on the NOO website allows examination of data on prevalence of obesity as well as the determinants of obesity and associated diseases at LA level. Data from the Active People Survey are also included.http://www.noo.org.uk/visualisation/eatlas
