Evaluation of the ‘Mealtime Magic’ brief leaflet-based intervention in general practice

Aim: To assess current primary care childhood obesity prevention activity and experiences of general practitioners (GPs) and practice nurses in delivering the ‘Mealtime Magic’ brief intervention. To determine the acceptability of the brief intervention and reported impact upon confidence and behaviour of parents. Background: A gap persists in the evidence base regarding brief childhood obesity prevention interventions in primary care, where good opportunities for primary prevention work lie. Methods: A quantitative and qualitative evaluation design, without control group, with post-intervention evaluation of parental outcomes and ‘before and after’ evaluation of healthcare professional perspectives was employed, using questionnaires. Five primary care practices in Worcestershire, England took part: six GPs, seven practice nurses (11 females and two males). 110 of 223 parents receiving the intervention completed follow-up measures (107 females, two males and one gender unknown; 106 White British). The intervention involved providing the ‘Mealtime Magic’ leaflet regarding childhood healthy eating behaviours, with verbal reinforcement of three main messages, to all parents with children aged five years and younger presenting to primary care over a six-week period. Staff received a 30-minute training session. Findings: Twelve of 13 health professionals ranked childhood obesity of importance relative to other priorities. Secondary prevention activities were undertaken more frequently than primary prevention. All professionals found the intervention easy to deliver; 12 of 13 stated they would use the leaflet in the future. Reported professional confidence in knowledge of evidence-based healthy eating behavior messages increased following intervention delivery. Resource barriers and perceived parental sensitivity with subject were reported. Ninety two percent (100/109) of parents stated the leaflet was helpful. Up to 52% (57/110) of parents reported more confidence regarding leaflet suggestions and up to 47% (49/105) reported positive behaviour changes. Evaluation of brief intervention approaches may help address perceived barriers to undertaking childhood obesity prevention work in primary care in the UK.
