Introduction• What’s obesity?
– Adults: BMI >= 30.– Kids: Age & Sex-Specific BMI
• What contributes to obesity?– Energy Balance Equation =
Energy Intake + Energy Expenditure
(CDC, 2007)

Introduction
• Research Questions/Hypotheses: (PI: Fuyuan Shen, Ph.D.; Co-PI: Changmin Yan, Ph.D.)
– Trends of media coverage on obesity; adults vs. kids.
– Agenda-Setting (McCombs & Shaw, 1972; 1993; Andsager & Powers, 2001)
• 1st level: issue salience
• 2nd level: issue frames

Introduction
• Research Questions/Hypotheses: – Framing of obesity causes and solutions.
• A news frame is a pattern of selection and salience (Entman, 1993; Reese, 2003).
• Causes: – Internal vs. External Attributions (Heider, 1958; Jones & Nisbett, 1972)
– Individual Behavioral vs. Systemic Attributions (Iyengar, 1991)
– Behavioral, Systemic, & Genetic Factors (CDC, 2007)
– RQ3: # of behavioral, systemic, & genetic frames for adults and kids.

Methods• Media: The New York Times
• Time Frame: Jan. 1, 1985 – Dec. 31, 2006.
• Key Words in Lexis-Nexis Academic Universe: “Obesity, Obese, and/or Overweight” in headline & lead paragraphs. 542 Stories.
• Coding: level of agreement > 90%, Krippendorff’s alpha > 0.70.

Methods• Coding Scheme: Causal Attributions
– Genetic and Biological Causal Claims– Influences on Food Intake
• Behavioral causal claims.• Systemic causal claims
– Influences on Physical Activity• Behavioral causal claims.• Systemic causal claims

Methods• Coding Scheme: Solutions (Lawrence, 2004)
– The Information Environment– Restrictions on Access to Calorie-Dense or Low-
Nutritional-Quality Foods– Economic Factors– Legal and Regulatory Environment– Prevention and Treatment Programs– Social Norms
