Obesity is a complex phenomenon without a single cause that needs comprehensive understanding and integrated
intervention. However, few researches have considered the media exposure, SES, lifestyle factors and their contributions
to the national problem of overweight and obesity comprehensively. To study the determinants of adults being
overweight or obese, a secondary analysis with national representative sample (ABC News/Time Magazine Obesity Poll)
was performed. Respondents were asked to rate their media exposures, behaviors of healthy diets and physical activities in
their lives. The research results reaffirmed that sedentary lifestyle (e.g., hours of watching television and physical inactivity)
in combination with dietary behavior of eating fat condensed food (e.g., frequent visits of fast food restaurant) have
increased probabilities to be overweight and obese.
