Reliability and Predictive Validity of Energy Intake Measures from the 24-Hour Dietary Recalls of Homebound Older Adults
University of Alabama at Birmingham
twentyfourhour dietary recalls used frequently study homebound older adults eating behaviors however reliability predictive validity method established population purpose study examine whether homebound older adults provide reliable valid measures total energy intake 24hour dietary recalls two hundred thirty homebound older adults interviewed homes using questionnaire assess eating behaviors factors could affect behaviors participants completed three 24hour dietary recalls baseline 6month followup two subsamples identified analyses participants hospitalized 6month interval weight measured assessments n52 sufficient testretest reliability energy intake observed r059 energy intake deficiencies relative estimated energy requirements predict actual weight loss r008 sample supplemented 91 participants experienced adverse event weight loss 25 hospitalization institutionalization mortality 6month period n143 adverse events likely occur insufficient energy intake odds ratio 349 p0009 white participants compared africanamerican participants odds ratio 313 p0016 adequate testretest reliability 24hour dietary recall demonstrated additional research larger samples longer followup intervals needed better evaluate predictive validity energy intake measures population
