Unhealthy eating increases risks for chronic disease. Few studies have examined the multifaceted aspects of dietary intake of low-income, urban African-American adolescents. This study aimed to describe dietary patterns including energy, nutrients, food groups, and diet quality and to identify areas to guide future interventions. Baseline data for a school-based obesity prevention study were collected from 382 African-American adolescents (10- to 14-year-olds) from four Chicago, IL, public schools in 2003. Diet was assessed using a 152-item food frequency questionnaire. Diet quality was measured using a modified version of the US Department of Agriculture Healthy Eating Index (HEI) and compared to published estimates for a nationwide sample. Participants reported high energy intakes and several unhealthy eating patterns: 58.6 % consumed one or more servings of sweetened beverages per day and 15.7 % consumed three or more servings per day; average fried food consumption was high (1.4 servings/day), 58.4 % consumed one or more serving per day; and 75 % consumed three or more three snacks per day. Only 49 % of participants met the recommended three servings of dairy foods per day. Compared to a national, mostly white sample, participants had lower HEI scores (P<0.05); mean score was 66.0±12.8 (100=maximum HEI score) vs 70.3±13.0 in boys vs girls, one third had scores <60 (“needs improvement”) and only 15 % scored >80 (“good”). This study reveals key areas of problematic dietary patterns for future interventions targeting low-income African-American adolescents, including frequent intakes of calorie-dense, low nutrient-rich foods, such as fried foods, snacks, and sweetened beverages.
