Obesity in United States
The Impact of Family Income on BMI
Fort Lauderdale April 15, 201
1.0 Executive Summary
The rising rate of obesity has reached epidemic proportions and is now one of the most serious
Public Health’s challenges facing the US. However, the underlying causes for this increase are unclear. This paper examines the effect of family income changes on body mass index (BMI) and obesity using data from the BRFSS, a state-based system of health surveys that generate information about health risk behaviors, clinical preventive practices, and health care access and use primarily related to chronic diseases and injury. A sample of 30 subjects has been randomly selected in the state of Florida for the year 2010; the causal impact of family income has been estimated on BMI in a set of women and men with BMI ≥ 30. Family income has been identified using differences in the level of annual salary earnings, individuals were organized in two categories:
Group I [$0 - $24,999]
Group II [$25,000 - ] The results indicate that income has a positive effect on BMI and the probability of being obese for low-income women and man, with the effect of income on BMI increasing over the BMI distribution.
Understanding the causal association between income and BMI would contribute to more effective public-health interventions, and if income positively affects obesity rates, avert counterproductive policies.

Weight has been rising in the United States throughout the twentieth century, but the rise in obesity since 1980 is fundamentally different from
