Americans Gaining More Weight Than They Say

Believe it.

Despite the increasing awareness of the problem of obesity in the United States, most Americans don't know whether they are gaining or losing weight, according to new research from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. Obesity increased in the US between 2008 and 2009, but in response to the questions about year-to-year changes in weight that were included in the most widespread public health survey in the country, on average, people said that they lost weight. Men did a worse job estimating their own weight changes than women. And older adults were less attuned to their weight changes than young adults. The findings are being published in the article "In denial: misperceptions of weight change among adults in the United States" in the August edition of Preventive Medicine.

"If people aren't in touch with their weight and changes in their weight over time, they might not be motivated to lose weight," said Dr. Catherine Wetmore, the lead author on the paper. "Misreporting of weight gains and losses also has policy implications. If we had relied on the reported data about weight change between 2008 and 2009, we would have undercounted approximately 4.4 million obese adults in the US."
