BackgroundSchool gardening programmes are increasingly popular, with suggested benefits including healthier eating and increased physical activity. Our objectives were to understand the health and well-being impacts of school gardens and the factors that help or hinder their success.MethodsWe conducted a systematic review of quantitative and qualitative evidence (PROSPERO CRD42014007181). We searched multiple databases and used a range of supplementary approaches. Studies about school gardens were included if they reported on physical or mental health or well-being. Quantitative studies had to include a comparison group. Studies were quality appraised using appropriate tools. Findings were narratively synthesised and the qualitative evidence used to produce a conceptual framework to illustrate how benefits might be accrued.ResultsEvidence from 40 articles (21 quantitative studies; 16 qualitative studies; 3 mixed methods studies) was included. Generally the quantitative research was poor. Evidence for changes in fruit and vegetable intake was limited and based on self-report. The qualitative research was better quality and ascribed a range of health and well-being impacts to school gardens, with some idealistic expectations for their impact in the long term. Groups of pupils who do not excel in classroom activities were thought to particularly benefit. Lack of funding and over reliance on volunteers were thought to threaten success, while involvement with local communities and integration of gardening activities into the school curriculum were thought to support success.ConclusionMore robust quantitative research is needed to convincingly support the qualitative evidence suggesting wide ranging benefits from school gardens.

Good nutrition in the early years of life is essential, yet the diets of many pre-school children in the UK are known to be poor. Understanding the decisions parents make when feeding young children is very important in determining what type and nature of interventional support may be developed to promote good nutrition. The aim of this study was to explore using qualitative methods, parental perceptions of feeding their children in order to inform the development of a nutrition intervention. Focus groups (n = 33) and individual interviews (n = 6) were undertaken with parents, most of whom were attending children's centres in two deprived populations from one urban (Islington, north London) and one rural (Cornwall) location in England. Accounts of feeding pre-school children were primarily concerned with dealing with the practicalities of modern life, in particular the cost of food and the need to manage on a restricted household budget. Time pressures, a lack of perceived knowledge and confidence in preparing food and managing conflict over food choices between family members were also strong themes. Parents commonly reported differences between how they would like to feed their children and the reality of what they were able to do in their circumstances. These findings suggest that the poor eating habits of many pre-school children may be less a case of parental ignorance but rather the product of a range of coping strategies. Designing an intervention, which helps parents to build their confidence and self-efficacy, may enable them to make positive changes to their children's diets.
