Assessing how middle school students' nutrient intake varies based on the availability of a la carte offerings at lunch

Purpose: School districts in the U.S. regularly offer foods that compete with the USDA reimbursable meal, known as `a la carte' foods. These foods must adhere to state nutritional regulations; however, the implementation of these regulations often differs across districts. The purpose of this study is to compare two methods of offering a la carte foods on student's lunch intake: 1) an extensive a la carte program in which schools have a separate area for a la carte food sales, that includes non-reimbursable entrees; and 2) a moderate a la carte program, which offers the sale of a la carte foods on the same serving line with reimbursable meals. ^ Methods: Direct observation was used to assess children's lunch consumption in six schools, across two districts in Central Texas (n=373 observations). Schools were matched on socioeconomic status. Data collectors were randomly assigned to students, and recorded foods obtained, foods consumed, source of food, gender, grade, and ethnicity. Observations were entered into a nutrient database program, FIAS Millennium Edition, to obtain nutritional information. Differences in energy and nutrient intake across lunch sources and districts were assessed using ANOVA and independent t-tests. A linear regression model was applied to control for potential confounders. ^ Results: Students at schools with extensive a la carte programs consumed significantly more calories, carbohydrates, total fat, saturated fat, calcium, and sodium compared to students in schools with moderate a la carte offerings (p<.05). Students in the extensive a la carte program consumed approximately 94 calories more than students in the moderate a la carte program. There was no significant difference in the energy consumption in students who consumed any amount of a la carte compared to students who consumed none. In both districts, students who consumed a la carte offerings were more likely to consume sugar-sweetened beverages, sweets, chips, and pizza compared to students who consumed no a la carte foods. ^ Conclusion: The amount, type and method of offering a la carte foods can significantly affect student dietary intake. This pilot study indicates that when a la carte foods are more available, students consume more calories. Findings underscore the need for further investigation on how availability of a la carte foods affects children's diets. Guidelines for school a la carte offerings should be maximized to encourage the consumption of healthful foods and appropriate energy intake.^

Student consumption of a la carte foods during school lunch meals

The purpose of this study was to evaluate students' lunch consumption compared to NSLP guidelines, the contribution of competitive foods to calorie intake at lunch, and the differences in nutrient and food group intake between the a la carte food consumers and non- a la carte food consumers.^ In Fall 2011, 1170 elementary and 440 intermediate students were observed anonymously during school lunch. The foods eaten, their source, grade level, and gender were recorded. All a la carte offerings met the Texas School Nutrition Policy.^ Differences in nutrient and food group intake by grade level and between students who consumed a la carte and those who did not were assessed using ANCOVA. A chi-squared analysis was conducted to evaluate differences in a la carte food consumption by grade level, gender, and the school's low income status.^ Average lunch intakes for elementary students were 457 (SD 164) calories for elementary students and 541 calories (SD 188) for intermediate students (p<0.001). 760 students (47%) consumed 937 a la carte foods, with the most often consumed items being chips (32%), ice cream (22%) and snack items (18%). Mean a la carte food intakes were 60 and 98 calories for elementary and intermediate schools respectively (p<0.001). Significantly more (p<0.000) intermediate students (34.3%) consumed a la carte items compared to elementary students (27.5%).^ Students who consumed a la carte foods had significantly higher intakes of calories (p<0.000), fat (p<0.000), sodium (p<0.002), fiber (p<0.000), added sugar (p<0.000), total grains (p<0.000), dessert foods (p<0.000), and snack chips (p<0.000) and lower intakes of vitamin A (p<0.001), iron (p<0.000), fruit (p<0.022), vegetables (p<0.031), milk (p<0.000), and juice (p<0.000) compared to students who did not eat a la carte foods.^ Although previous studies have found that reducing availability of unhealthy items at school decreased student consumption of these items, the results of this study indicate that even the strict guidelines set forth by the state of Texas are not sufficient to prevent increased caloric intake and poor nutrient intake. Strategies to improve student selection and consumption at school lunch when a la carte foods are available are warranted.^
