title: The feasibility of personal digital assistants (PDAs) to collect dietary intake data in low-income pregnant women.
abstract: OBJECTIVE
  To determine the feasibility of using personal digital assistant (PDA)-based technology for tracking and analysis of food intake in low-income pregnant women.
  
  
  METHODS
  Descriptive. Participants provided an initial 24-hour dietary recall and recorded their food intake using a PDA-based software program for 2 days.
  
  
  METHODS
  Recruitment occurred during the prenatal intake visit at a health department-sponsored Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinic.
  
  
  METHODS
  Nonprobability sampling was used to recruit 10 women. VARIABLE MEASURED: Demographics and a satisfaction rating scale for the 2 food recording methods. A Healthy Eating Index (HEI) was calculated for each food record.
  
  
  METHODS
  Scores of the satisfaction rating scales were summarized. Paired t tests were used to analyze differences in HEIs obtained from the participants' 24-hour recall and PDA-based food records.
  
  
  RESULTS
  The PDA was significantly easier to use compared to the 24-hour recall, and no significant differences in ease of remembering food intake between these methods was noted. Most women liked the PDA and felt it was more accurate than 24-hour recalls. Results showed no significant difference in mean HEI scores between food records from 24-hour recall to PDA.
  
  
  CONCLUSIONS
  PDA-based software may be an acceptable method for obtaining food records to provide more accurate assessments of dietary intake in this vulnerable population.
