Prevalence and Odds of Obesitya by Frequency of Fast-Food Consumptionb Among Michigan Adults, Michigan Behavioral Risk Factor Survey, 2005
| Frequency of Fast-Food Consumption | Obesity Prevalence,% (95% CI) | Odds Ratio (95% CI) | Adjusted Odds Ratio (95% CI) |
|---|---|---|---|
| < once/wk | 24.1 (22.1-26.3) | 1 [Reference] | 1 [Reference] |
| 1 to <2 times/wk | 26.4 (23.2-29.8) | 1.13 (0.92-1.38) | 1.27 (1.00-1.61) |
| 2 to <3 times/wk | 32.2 (27.6-37.1) | 1.49 (1.16-1.91) | 1.60 (1.21-2.13) |
| ≥3 times/wk | 32.9 (28.0-38.1) | 1.54 (1.19-1.99) | 1.81 (1.35-2.44) |
Abbreviation: CI, confidence interval.
a
Body mass index (BMI), ≥30.0 kg/m2.
b
Consumed fast food ≥2 times/wk based on the question, "How often do you usually go to a fast-food restaurant?
c
Adjusted odds ratios from a logistic regression with obesity (BMI ≥30.0 kg/m2) as the dependent variable, frequency of fast-food consumption as the independent variable, and age, sex, race, urbanicity, children in household, education, household income, general health status, fruit and vegetable consumption, and adequate physical activity as possible confounding variables.
