摘要: Current methods for evaluating food marketing to children often study a single channel or approach. As the World Health Organization urges removal of unhealthy in children’s settings, that comprehensively explore exposure and power within setting from multiple channels approaches are needed. The purpose this was test inter-rater reliability validity novel settings-based audit tool. Food beverage Marketing Assessment Tool Settings (FoodMATS) developed its psychometric properties evaluated five public recreation sport facilities (sites) subsequently used 51 sites across Canada cross-sectional analysis marketing. Raters recorded count occasions, presence child-targeted sports-related techniques, physical size occasions. occasions were classified by healthfulness. Inter-rater tested using Cohen’s kappa (κ) intra-class correlations (ICC). FoodMATS scores each site calculated an algorithm represented theoretical impact environment on preferences, purchases, consumption. Higher with higher to, more powerful (unhealthy, child-targeted, sports-related, large) Validity scoring through (1) Pearson’s between facility sponsorship dollars, (2) sequential regression predicting “Least Healthy” sales scores. very good excellent (κ = 0.88–1.00, p < 0.001; ICC = 0.97, p < 0.001). There strong positive correlation after controlling (r = 0.86, p < 0.001). score explained 14% variability concession (p = 0.012) 24% total vending (p = 0.003). has high validity. first validated tool evaluate facilities, provides means track changes environments can assist developing monitoring policies interventions.
