Proposed factors and barriers/enablers influencing the delivery of interventions to promote healthy infant feeding within primary care

Factors influencing the acceptability of delivering infant feeding interventions in primary care		Anticipated barriers to delivering infant feeding interventions in primary care (TFA construct coded)	Proposed enablers to delivering infant feeding interventions in primary care (TFA construct coded)
Resources:	Time and funding	• Lack of staffing capacity (i.e. time/funding) to deliver intervention (B) • Increased recent complexity and therefore time needed for vaccination visits * (B, PE)	• Incentivising involvement via audit, payment/staffing, free training, etc (B, OC) • Vaccination visits providing ease of access to child at routine periods * (PE)
	Training and materials	• Lack of available training/trustworthy resources (SE)	• A recognised need for more infant feeding support/training/resources for parents (SE) • Access to training/trustworthy resources for HCP (SE)
Roles and priorities:	Professional roles and priorities	• Too many competing priorities within existing HCP role (B, AA) • Childhood obesity/infant feeding not perceived as part of HCP role (AA)	• Multidisciplinary team involvement – viewed as an issue where all have a role to play (AA)
	Personal piorities	• Childhood obesity/infant feeding not in HCP’s personal area of special interest (E, AA)	• Perceived importance of childhood obesity/infant feeding – long-term social/economic implications (E, AA) • HCP having existing special interest in/personal experience with childhood obesity/infant feeding (E, AA)
Communication:	Message consistency and clarity	• Lack of message/information consistency across HCP (PE) • Conflicting information from other influences (peers, media, etc) (PE)	• Ensuring consistency of messages/information across all HCP (PE)
	Supportive relationships/communication	• Challenges of communicating childhood obesity/infant feeding in a sensitive manner (SE, AA) • Communication challenges due to increased parental stress/anxiety during vaccinations * (SE,PE)	• Positive, supportive relationships/communication between primary care HCP and parents (SE, AA) • Ease of communication due to decreased parental anxiety due to child not being medically ill at time of vaccinations * (SE, PE)

TFA, Theoretical Framework of Acceptability; B, Burden; OC, Opportunity Costs; PE, Perceived Effectiveness; SE, Self-Efficacy; HCP, healthcare professional; AA, Affective Attitude; E, Ethicality.
