Recent increases in obesity have been linked to the increased rates of cancer in the US. To explore the relationship between adulthood obesity patterns and risk for obesity-related cancers, we explored adult weight gain patterns among those with a diagnosis of obesity-related cancers compared to those with non-obesity related cancers or no cancer history. Adults (>45 years) from the 1999-2004 National Health and Nutrition Examination Survey (NHANES) with complete weight history and medical conditions questionnaires were included. NHANES is a program of studies designed to assess the health and nutritional status of the U.S. population. Weight patterns were assessed using weight changes since heaviest weight, 25 years of age, 10 years ago, and 1 year ago. Mean differences in current weight status and patterns were compared across cancer diagnosis groups. Those with no cancer history had significantly greater annual weight change since age 25 and over the past 10 years than participants with previous cancer history. Men with obesity- and non-obesity related cancer histories were at a significantly lower percentage of their heaviest body weights than those with no cancer history. As for females, annual weight change since age 25 was significantly lower with non-obesity related cancer history than those with no cancer history. Assessing weight change patterns provides useful information about predicting obesity-related cancers; however, more data is needed to describe this relationship.
