Abstract

OBJECTIVE:

To examine the cross-sectional relationships between physical activity and dietary behaviors among 8- to 10-year-old African-American girls.

RESEARCH METHODS AND PROCEDURES:

Two hundred ten 8- to 10-year-old African-American girls from four field centers participated. Computer Science and Applications (CSA) activity monitors were worn for 3 days. CSA data were expressed as mean CSA counts per minute, mean minutes of moderate to vigorous activity per day, and mean metabolic equivalents (METS) per minute. Two nonconsecutive 24-hour dietary recalls were analyzed for kilocalories; percent kilocalories from fat; daily servings of fruit, 100% fruit juice, and vegetables; sweetened beverages; and water consumption. Height and weight were measured, and information on household income, material possessions, and participant age were obtained.

RESULTS:

All three expressions of physical activity were significantly negatively associated with percentage calories from fat (r = -0.147 to -0.177, p < 0.01), and mean METS per minute were significantly positively associated with percentage calories from carbohydrate (r = 0.149, p < 0.05) after controlling for household income, material possessions, field center, and total caloric intake. Income was inversely associated with percentage calories from fat.

DISCUSSION:

Physical activity and dietary fat consumption were inversely related among African-American girls. Efforts to prevent obesity in preadolescent African-American girls should focus on increasing physical activity and lowering dietary fat consumption.
