Objective: To evaluate the impact of increased availability of healthier options on purchasing of different types of vending snack products sold in English leisure (sports) centres. Design: An evaluation of an intervention using pre-post methods and interrupted time series analysis. Products within the vending machines were altered over three phases to increase the availability of healthier options, using agreed nutrition criteria – Government Buying Standards for Food and Catering Services (GBSF) for England – as a guide, as well as product availability. The primary outcome was the change in mean weekly purchased energy between the first and third phase. Secondary outcomes included changes by phase and by week in weekly number of purchases, fats, sugars and salt for all products combined and by individual product categories. Setting: Fifteen sports centres in the city of Leeds, West Yorkshire, UK. Participants: Snack products sold in eighteen vending machines. Results: Energy purchased reduced from baseline to phase 2, for all product categories combined, by 47·25 MJ (95 % CI (−61·22, −33·27)) per machine and by 279 kJ, (95 % CI (−325, −266)) per product unit. There were reductions in most nutrients purchased in all individual product categories except chocolate confectionery. Nutrients per product unit decreased for all product categories except saturated fat in chocolate confectionery. Minimal underlying trends in the baseline phase were identified, indicating changes in outcomes were likely to be due to the intervention. Conclusions: Introducing standards to increase availability of healthier snack products in vending machines is feasible without substantially affecting sales. [ABSTRACT FROM AUTHOR]

ObjectiveTo evaluate the effectiveness of the Ministry of Food (MoF) cooking programme on self-reported food consumption and confidence with cooking.DesignA quantitative and qualitative evaluation of the MoF 8-week cooking course, using a pre-test/post-test study. Pre, post and 6-month follow-up quantitative outcomes were measured using self-administered questionnaires to record number of portions of fruit and vegetables (F&V) consumed per day, number of snacks consumed per day and participants’ cooking confidence levels (highest score of 5). Qualitative evaluations were undertaken using structured telephone interviews.SettingMoF centre in Leeds Kirkgate Market, UK.SubjectsAdults (n 795, 43 % male) on MoF courses from 2010 to 2014, 462 of whom completed questionnaires at all three time points.ResultsSix months after the course, self-reported F&V intake increased significantly by 1·5 (95 % CI 1·3, 1·6, P<0·001) portions per day to 4·1 (95 % CI 4·0, 4·3). The number of snacks reported decreased significantly over the same period by −0·9 (CI−1·0, −0·8, P<0·001) snacks per day. Cooking confidence increased over the same period by 1·7 (95 % CI 1·6, 1·9, P<0·001) to 4·4 (CI 4·4, 4·5). Age and disability, but not deprivation or ethnicity, were associated with changes in self-reported F&V intake and cooking confidence scores at 6 months; and gender with the latter outcome. Qualitative results supported quantitative findings and revealed specific beneficial gains in cooking skills/preparation, nutritional awareness, food purchasing and other social benefits.ConclusionsMoF community-based cooking interventions can have significant positive effects on dietary behaviour, food choice and cooking confidence.
