BOONE, N.C. — Is picky eating more than an acknowledged childhood phase?
Research by Appalachian State University alumnus Jordan Ellis ’15, Dr. Amy Galloway, professor in the university’s Dr. Wiley F. Smith Department of Psychology, and others indicates appetitive behaviors such as picky/fussy eating may carry over from one’s child and adolescent years into adulthood.
The article detailing their findings, titled “A functional description of adult picky eating using latent profile analysis,” appeared in the online, peer-reviewed International Journal of Behavioral Nutrition and Physical Activity (IJBNPA) — the official journal of the International Society of Behavioral Nutrition and Physical Activity — in November 2018. IJBNPA is a publication of BioMed Central (BMC) Ltd., which is a part of Springer Nature.
In the paper’s abstract, the authors state, “Previous research identified a (picky eater) PE profile in children, marked by high food avoidance (satiety responsiveness, fussiness, and slow eating) and low food approach (food enjoyment and responsiveness) appetitive traits.
“Research has indicated that adult picky eating (PE) is associated with elevated psychosocial impairment, as well as limited dietary variety and fruit and vegetable intake.”
The team completed their research by using data collected from a sample of 1,339 U.S. adults recruited through Amazon’s Mechanical Turk (MTurk), an online marketplace where both companies and individuals can coordinate the use of human intelligence to perform tasks outside the ability of computers.
The study participants completed an online survey that included a modified self-report version of the Child Eating Behavior Questionnaire (CEBQ-A), a parent-rated instrument designed to assess eight dimensions of eating style in children developed through previous research by faculty at University College London.
According to the study’s results, participants in the picky eater profile (18.1 percent) scored higher on measures of adult picky eating and social eating anxiety compared to all other profiles. Additionally, those in the picky eater profile scored higher on eating-related impairment and depression than those in the moderate eater profile and were more likely to be of normal weight.
Through the team’s research, a distinct adult PE profile was observed, indicating childhood PE and appetitive behaviors may carry over into adulthood.
“Research identifying meaningful groups of picky eaters will help to shed light on the conditions under which picky eating is a risk factor for significant psychosocial impairment or distress, or weight-related problems,” the authors state in the paper’s abstract.
Appalachian’s Office of Student Research provided some funding for Ellis and Galloway’s project.
