Comparison of Traditional Interviewer‐Administered 24‐Hour Dietary Recall with Web‐based Automated Self‐Administered 24‐Hour Dietary Recall in South Asian Students

Abstract

Web‐based automated self‐administered 24‐hour recall (ASA24) method offers a reliable and low‐cost means of dietary assessment in large populations. However, studies comparing its use with traditional interviewer‐administered 24‐hour dietary recall (IA24) method in immigrant populations are lacking.ObjectiveTo compare diets assessed by ASA24 and IA24 in South Asian student population at an urban senior college.MethodsSouth Asian students (n=40) were interviewed for a 24‐hour dietary recall using the automated multiple‐pass method. Students also completed another 24‐hour dietary recall online using ASA24 method. Differences in frequently reported items between methods were evaluated. Intakes of selected nutrients and food groups between methods were compared. Qualitative data on ease of using ASA24 were collected in a follow‐up interview.ResultsFood group and nutrient intakes were similar between the two methods. Statistically significant differences were found for unadjusted means of fruit as a food group (p=0.028), cholesterol (p=0.030), calcium (p=0.029), and folate (p=0.000) intakes. After controlling for gender, only cholesterol remained significantly different (p=0.015). Review of food lists revealed that ethnic South Asian foods were more represented in IA24 data.ConclusionASA24 captured dietary intakes with sufficient accuracy and was comparable to the traditional interviewer‐administered 24‐hour dietary recall in this sample of South Asian college students.Support or Funding InformationNone
