Factors that influence the implementation of dietary guidelines regarding food provision in centre based childcare services: a systematic review

Children attending centre based childcare services consume as much as two thirds of their daily dietary requirements while in care. However, such services often fail to provide foods that are consistent with guideline recommendations. Developing strategies to improve childcare service adherence to menu dietary guidelines requires a comprehensive understanding of factors that may impede or promote implementation. The primary aim of this systematic review is to describe factors (barriers and facilitators) that may influence the implementation of menu dietary guidelines regarding food provision in centre-based childcare services and to map these factors to a theoretical framework. Over 7000 citations were identified from all sources. Duplicate abstracts were removed and selection criteria applied. Twelve studies (1994-2015) were included in the review. Dual data extraction was conducted and the reported factors were synthesised using the theoretical domains framework (TDF). Barriers and facilitators identified in qualitative studies were classified into 8 and 10 of the 14 TDF domains. Barriers and facilitators reported in quantitative studies covered 6 and 3 TDF domains respectively. The most common domain of which both barriers and facilitators to the implementation of menu dietary guidelines were identified was 'environmental context and resources'. This is the first study that comprehensively assesses literature to identify factors that influence the implementation of menu dietary guidelines in childcare services utilising a theoretical framework. Findings provide guidance to support researchers and policy makers design strategies to improve menu dietary guideline implementation and, as such have the potential to improve food provision in care
