Hypothesis

How have public perceptions of overweight changed in Great Britain over an eight-year period?

Conclusion

Despite health campaigns, more overweight individuals fail to recognize their weight as a concern.

Supporting Evidence

  • In 1999, 81% of overweight participants identified as overweight, compared to 75% in 2007.
  • The proportion of respondents classified as obese nearly doubled from 11% to 19% between 1999 and 2007.
  • Women in the 2007 sample were slightly older than those in the 1999 sample.

Takeaway

People in Great Britain are less likely to think they are overweight now than they were eight years ago, even though more people are actually overweight.
