Appalachian adolescents' snack patterns: morning, afternoon, and evening snacks.

The snack patterns of 225 adolescents selected from four metropolitan and three rural schools in eastern Tennessee were examined with the use of 24-hour food records kept on a school day. Most (89%) of the respondents ate at least one snack on the day of the survey. Morning snacks, most of which were obtained from school stores or school vending machines, were more likely to include candies and salty snack foods than were afternoon and evening snacks, most of which were eaten at home. Breads and cereals were popular choices for afternoon and evening snacks. Carbonated beverages and desserts were popular during all time periods. Nutrient densities of snacks were low in all time periods but lowest in morning snacks. Nutrients present in lowest amounts were iron, calcium, and vitamin A. Snack patterns of boys and girls were similar, although boys' intakes of energy, calcium, and riboflavin were higher than those of girls.

Appalachian adolescents' eating patterns and nutrient intakes.

Meal and snack patterns of 114 male and 111 female adolescents in a southern Appalachian state were examined from 24-hour food records kept on a school day. Breakfast was skipped by 34% of the respondents, and 27% either skipped lunch or ate a snack-type lunch. The evening meal and snacks, each of which contributed about one-third of the daily energy intake, were eaten by 94% and 89%, respectively. Girls' mean intakes of vitamin A, calcium, and iron were low at all eating occasions throughout the day. Boys' mean intakes of iron were low at breakfast, lunch, and snacks; their vitamin A intakes were low at lunch and snacks. Adolescents who prepared their own breakfasts consumed less energy, protein, fat, and niacin at that meal than did adolescents who ate breakfasts prepared by their mothers. However, adolescent-prepared breakfasts were higher in nutrient density for calcium, riboflavin, and thiamin. Evening meals prepared by adolescents were similar in total nutrient content to meals prepared by their mothers but lower in nutrient density for iron and thiamin. Evening meals prepared by adolescents were more likely to include a sandwich and less likely to include a vegetable than were meals prepared by mothers.
