Abstract
Description
This cross-sectional study utilized BRFSS and US census data to create Hierarchical Linear Models (HLM) with three levels. Level 1 was individual differences, level 2 was time, and level 3 was place. The HLM models were constructed to review BMI and obesity (BMI30). High BMI as well as obesity were associated with low income, lack of college education, and race/ethnicity. The results show that obesity rates are increasing over time, with the rate of increase starting to slow. They also show differences in the prevalence of obesity by place. These findings have implications for the treatment and prevention of obesity in the United States. PSY 296B, Senior Thesis, Dr. David Schlundt.
