title: Food serving size knowledge in African American women and the relationship with body mass index.
abstract: OBJECTIVE
  To examine serving size knowledge in African Americans and how it is related to body mass index (BMI).
  
  
  METHODS
  Serving size knowledge of food commonly consumed by African Americans was assessed by asking the subjects to select the amount of food considered to be a single serving size by the United States Department of Agriculture and the Food and Drug Administration. Seventeen food items were tested, and the amounts selected were weighed. Body mass index was estimated from measured height and weight.
  
  
  METHODS
  Churches.
  
  
  METHODS
  Ninety-five African American women.
  
  
  METHODS
  Amount of food selected and BMI.
  
  
  METHODS
  The amount of food selected was compared with the respective standard serving using the 1-sample Wilcoxon signed rank test. The association between BMI and the amount selected was assessed by logistic regression.
  
  
  RESULTS
  The subjects significantly overestimated (P = .001 to .02) serving sizes for cornflakes, apple, watermelon, butter, whole milk, chips, and regular soda. Body mass index was significantly associated with overestimation of cornflakes, butter, cookies, and macaroni and cheese (P = .01 to .03), and the odds ratio for overestimating these food items was 1.46-1.65 times greater per 5-unit increase in BMI.
  
  
  CONCLUSIONS
  African American women overestimated the serving sizes for 7 of the food items tested, and 4 of the estimates were correlated with BMI. Education regarding serving size is recommended for certain food items.
