Self-reported versus Measured DataSelf-reported versus Measured Data
• Self-reported height and weight measurements give a systematic underestimation of the true prevalence of respondents who are overweight or obese
• Does not detract from the importance of monitoring trends since this underestimation would have been present in 1998 and 2002 SLÁN Surveys
• Self-reported height and weight estimates continue to be widely used world wide to monitor trends over time
• Measured data are preferred when determining the true extent of overweight and obesity

Self-reported BMI Distribution TrendsSelf-reported BMI Distribution Trends
• Overweight levels increased– 1998: 31%– 2002: 33%– 2007: 36%
• Obesity levels stabilised– 1998: 11%– 2002: 15%– 2007: 14%
• Trends in Overweight Prevalence by Sociodemographic Characteristics, 2002-2007
– Gender• Men: 38% 43%
– Age• 18-29yrs: 19% 23%

Comparison of Measured and Self-Reported Height, Weight and BMI
• Height was reported accurately across all categories
• Weight was underreported among both men and women (~4%)
• BMI calculations were affected by underestimation of weight

Central ObesityCentral Obesity
• Associated with an increased risk of diabetes and CVD beyond the risk of associated with generalised obesity
• Defined as a large waist circumference exceeding standard thresholds:
– Male threshold >94cm (37in)
– Female threshold >80cm (31.5in)

ConclusionsConclusions
• The high prevalence of overweight and obesity in Irish adults poses a major threat to the health and well-being of the Irish population
• Based on measured data, almost 2 out of 3 Irish adults were at an unhealthy weight – approximately one out of 4 adults was obese
• Based on self-reported data, the prevalence of overweight has increased, though obesity levels have stabilised among men and women
• More than half of Irish adults have a mean waist circumference exceeding the threshold for central obesity
• The prevalence of obesity is broadly similar to that reported from England (2006) and Scotland (2003), and approximately 5% lower than in the USA (2004)
