Filter by:Background: While there is some evidence that increasing the range of healthier foods and drinks and/or decreasing the range of less healthy options may increase healthier choices, more work is needed to establish the reproducibility of any effect. The current study aims to investigate the impact of altering the availability of healthier and less healthy foods and cold beverages in hospital vending machines. Methods: An adapted multiple treatment reversal design will be used, in which all standard vending machines serving snack foods and/or cold beverages in one hospital in England change the number of slots containing (i) less healthy items and (ii) healthier items over eight 4-week periods. Changes will take place in a two-step process whereby decreases are implemented in a separate study period prior to increases in the contrasting food group. Following a 4-week baseline period, all vending machines will be standardised to have 75% healthier drinks and/or 25% healthier snacks (study period 1). Vending machines (n=9) will be randomly allocated to the order in which they: (1) decrease less healthy foods and increase healthier foods or (2) decrease healthier foods and increase less healthy foods (study periods 2&3 and 5&6). After each decrease-increase pair, machines will return to the standardised 75% healthier drinks and 25% healthier snacks (study periods 4 and 7). Sales data will be obtained via records of machine restocking. Planned Analysis: The impact of the availability intervention will be assessed in separate linear mixed models for cold drinks and snacks, examining the impact on total energy (kcal) purchased, per restocking interval, with random effects for vending machine.
This training program is a part of Happy Family Kitchen Movement Project, which is a community-based research project with 3 main components for data collection - training programs, community-based family interventions and public education events. The training program involves various organizations, including non-government organizations and schools across districts in different regions of Hong Kong. In the study, the investigators would use training programs as a capacity building method and an essential media delivering the holistic health knowledge (positive psychology, physical activity, healthy diet) to the public. The project team will provide training program for the participants, including: (i) train-the-trainer workshops for the social service workers, who will conduct community-based family intervention programs; and (ii) train-the-trainer ambassadors for the volunteers who may assist to implement health-related activities for the public.
1. Development of a method for parents of primary schoolchildren to teach parents parenting skills to obtain health gain in the family through videos and online feedback. 2. Effect- and procesevaluation of this methodology. 3. Development of an implementation guide together with VIGEZ as primary partner and in association with partner organisations on the field.
