Similar 24-Hour Dietary Recall Results from Low-Income Women When Collected by a Paraprofessional Nutrition Educator or Registered Dietitian Nutritionist.

BACKGROUND

The Expanded Food and Nutrition Education Program (EFNEP) is a federally funded, community nutrition education program that assists the low-income population in acquiring knowledge and skills related to nutrition, food safety, food resource management, food security, and physical activity. Evaluation of EFNEP includes a 24-hour dietary recall (24HDR) administered by paraprofessional educators, yet protocols for most large-scale nutrition research studies employ registered dietitian nutritionists (RDNs) or individuals with educational backgrounds in nutrition or related fields to collect dietary recalls.

OBJECTIVE

To compare 24HDRs collected by trained paraprofessional educators with recalls collected by an RDN.

DESIGN

Exploratory cross-over study comparing same-day 24HDR in a one-on-one setting collected by paraprofessional educators and an RDN. Paired recalls were separated by at least 1 hour.

PARTICIPANTS AND SETTING

The participants (n=41) were volunteer women who were eligible for participation in EFNEP in two states.

MAIN OUTCOME MEASURES

The 24HDRs were compared for energy, macronutrients, micronutrients, and food groups.

STATISTICAL ANALYSIS PERFORMED

Mixed-model analysis to account for repeated measures. Intraclass correlation and Spearman correlation coefficients to determine interrater agreement.

RESULTS

No difference in 24HDR was seen when compared by interviewer (paraprofessional vs RDN) or by site (Colorado vs North Carolina). There were significant differences in four components (energy, total fat, saturated fat, and solid fats-added sugar) based on recall order, with a higher intake in the second recall compared with the first.

CONCLUSION

The results of this preliminary study suggest that a well-trained paraprofessional educator using a valid methodology can collect a 24HDR that is similar to a recall collected by an RDN. The paraprofessional educator can be employed for dietary data collection, allowing the RDN to focus on more advanced aspects of scope of practice, such as data evaluation and program development.
