24-Hour Dietary Recall Collection

The NCC Service Center has extensive expertise and experience in conducting 24-hour dietary recall interviews via telephone with a variety of populations, including children. Centralized collection of 24-hour dietary recalls is valuable for multi-centered sites where standardization of data collection enhances overall dietary data quality. Outsourcing of dietary data collection is also useful for single study center sites where nutrition staff are limited or unavailable.

Interviews take place over the telephone using NDSR, and are conducted by trained and certified NCC staff. Because dietary practices have been found to vary by time of week, interviews are scheduled to capture both weekend and weekday intakes.

The NDSR multiple-pass interview methodology allows the respondent repeated opportunities to recall their intake within the past 24 hours and to provide detailed food descriptions. Food portion estimation visual aids are provided to respondents to assist in portion size estimation.
