Weight bias among children and parents during very early childhood: A scoping review of the literature.

OBJECTIVE

Exposure to and endorsement of weight bias attitudes are risk factors for poor mental health and weight-related outcomes among children and youth. Better understanding early-emerging weight bias, and how parents of young children may influence development of weight bias, may help reduce its occurrence. Although early childhood (under 5 years) is a developmental period characterized by increasing social-cognitive abilities to categorize others based on external features such as weight, little is known about the emergence or socialization of very early weight bias. The aim of this review was therefore to investigate weight bias and its correlates among very young children and parents of very young children as potential socialization agents.

METHODS

A comprehensive search strategy was used to search electronic databases for studies that examined weight bias attitudes among children and parents. The review included studies that assessed weight bias in children and/or parents of children ages 1-3 years old (some including 3-5 year-olds), and that were published in English between 2011 and 2021.

RESULTS

Thirteen of the 1748 identified studies met inclusion criteria. Only two studies used a longitudinal design. Seven of eight studies of children used behavioral tasks to assess child weight bias; among the 10 studies including parents, 4 used interviews and 6 used questionnaires to assess parent weight bias. Children were found to display anti-fat and pro-thin bias, with bias more prevalent among older children. Positive associations between parent and child weight bias were found in four studies.

CONCLUSIONS

Child weight bias emerges prior to age 3 years and shows some association with parent weight bias. Future research should employ longitudinal designs to characterize influences on emerging weight bias among very young children.
