Abstract

Objective To determine if 24-hour dietary recall data are influenced by whether data are collected by telephone or face-to-face interviews in telephone and non-telephone households.

Design Dual sampling frame of telephone and non-telephone households. In telephone households, participants completed a 24-hour dietary recall either by face-to-face interview or telephone interview. In non-telephone households, participants completed a 24-hour dietary recall either by face-to-face interview or by using a cellular telephone provided by a field interviewer.

Subjects/setting Four hundred nine participants from the rural Delta region of Arkansas, Louisiana, and Mississippi.

Main outcome measures Mean energy and protein intakes.

Statistical analyses performed Comparison of telephone and non-telephone households, controlling for type of interview, and comparison of telephone and face-to-face interviews in each household type using unpaired t tests and linear regression, adjusting for gender, age, and body mass index.

Results Mean differences between telephone and face-to-face interviews for telephone households were −171 kcal (P=0.1) and −6.9 g protein (P=0.2), and for non-telephone households −143 kcal (P=0.6) and 0.4 g protein (P=1.0). Mean differences between telephone and non-telephone households for telephone interviews were 0 kcal (P=1.0) and −0.9 g protein (P=0.9), and for face-to-face interviews 28 kcal (P=0.9) and 6.4 g protein (P=0.5). Findings persisted when adjusted for gender, age, and body mass index. No statistically significant differences were detected for mean energy or protein intake between telephone and face-to-face interviews or between telephone and non-telephone households.

Applications/conclusions These data provide support that telephone surveys adequately describe energy and protein intakes for a rural, low-income population. J Am Diet Assoc 2001:101:216-222.

Sample

The Foods of Our Delta Study (FOODS) was designed to validate telephone-administered 24-hour dietary recalls in Chicot County, Ark, Madison Parish, La, and Yazoo County, Miss. Two sets of households were identified: telephone households using list-assisted random digit dialing (RDD) (25), and non-telephone households using area survey sampling (26). A non-telephone household was defined as a household with no working telephone. Following recruitment and identification of persons living in

Results

Of the 321 telephone numbers that were sampled and determined to be residential numbers of households, 197 completed the household screen, yielding a response rate of 60%; 16 households were ineligible because of residency requirements. Of the remaining households, 138 agreed to complete the dietary interview, yielding 200 24-hour dietary recalls from adults and children (Table 1). In the area sampling survey to identify non-telephone households, 1,661 households were contacted, 153 were

Discussion

Assessing the nutritional health, food, and nutrient intakes of persons living in rural, low-income areas is extremely important in light of their risk to food insecurity, and limited access to and availability of nutritionally complete diets. Importantly, we have shown in this first validation study for telephone-administered 24-hour dietary recalls concentrated in a low-income rural population in the Lower Mississippi Delta, that telephone surveys may adequately describe mean energy and

Applications
  • The use of telephone surveys may adequately describe mean energy and protein intakes for a rural, low-income population. This is an important finding because use of telephone interviews increases access to remote and rural areas.

  • There were no statistically significant differences between the telephone and non-telephone households, regardless of interview type. To our knowledge, this is the first study designed to collect and compare dietary data and methodology between telephone and non-telephone households, and it contributes to our knowledge and understanding of dietary methodology.

  • The efficacy of this study was increased by the use of the multiple-pass method, interview techniques, and database from a nationwide survey, as well as adaptation to food probes and recipes that were needed to address specific regional language, literacy, recipes, and food patterns.
