BackgroundIn primary healthcare, conversations between clinicians and parents about young children’s overweight are key to providing support and initiating weight management. However, given the sensitivity of this topic, these conversations are difficult for both clinicians and parents and are sometimes delayed or avoided. To understand the emotional impact of these conversations, this study aims to shed light on parents’ experiences following conversations with primary care nurses about their child’s overweight.MethodsParticipants were recruited through a childhood obesity randomized controlled trial (RCT) conducted in Sweden. Telephone-based semi-structured interviews were conducted with 17 parents (mean age 40; the majority were women (n = 12/17), had a university degree (n = 14/17) and were born in Sweden (n = 13/16)). Their children were between 3 and 7 years old (mean age 4.8 years) with overweight (n = 7) or obesity (n = 10). The interviews were recorded, transcribed, and analyzed using thematic analysis.ResultsTwo main themes were developed. Theme 1, ‘Receiving the overweight/obesity diagnosis’, explores parents’ reactions to the conversation with the primary care nurse. Depending on how the nurse presented the topic, conversations either fostered an alliance between the parent and the nurse, encouraging parents to reflect and develop insights about the child’s and the family’s needs (subtheme Conversations that empower), or felt limited, uncomfortable, or belittling (subtheme Conversations that provoke resistance). Theme 2, ‘Parenting a child with a formal diagnosis of obesity’, explores challenges parents faced following the weight conversations, including managing their own feelings and concerns (subtheme Fear of transferring weight anxiety), dealing with others’ reactions (subtheme Involve family and manage surroundings) and asking for and receiving support from health care professionals (subtheme Obtain support from health care professionals).ConclusionsWhile conversations with primary care nurses about children’s weight were often emotional, most parents felt these conversations were ultimately helpful, as they encouraged them to enact positive lifestyle changes. Importantly, when nurses initiated conversations in a responsive, non-blaming way, inviting parents to reflect on their situation, parents felt more supported and empowered. These findings convey the importance of providing communication skills training to pediatric healthcare professionals, with particular focus on childhood overweight and obesity.Trial registration numberClinicalTrials.gov NCT03800823; 11 Jan 2019.
