SummaryBackgroundStigma towards children with obesity can begin as early as 3 years old, leading to increased risk for poorer mental health outcomes and lower quality of life. This includes discriminatory language used by peers and adults, which may be compounded by use within the medical community and in published research.ObjectivesOur primary objective was to investigate adherence to person‐centred language (PCL) in childhood obesity‐related medical publications.MethodsWe searched PubMed for childhood obesity‐related articles from 2018 through 2020, from journals frequently publishing childhood‐obesity‐related research. Articles were randomized and searched for a list of predetermined, stigmatizing terms.ResultsOf the sample of 300 articles, only 21.7% were adherent to PCL guidelines. The most frequent labels found were ‘obese’ appearing in 70.33% of articles and ‘overweight’ in 63.7%. Labels such as ‘chubby’, ‘large’, and ‘fat’ were less common, but still appeared in the medical literature.ConclusionsA majority of childhood obesity‐related articles did not adhere to PCL guidelines. Given the negative effects of stigma among children with obesity, it is imperative to advocate for PCL use within the medical community. Increased stringency by journal editors and publishers may be the next step in this process.
