Abstract

The consumption of low nutritional quality food in large quantities is an important public health problem, encompassing social, individual, economic and cultural factors. Nutritional intervention in the environment to improve the availability of healthy foods in urban areas has been identified as a promising and sustainable strategy. Will be test and adapt the methodology used by the research group from Johns Hopkins University in intervention studies for small food stores, with the use of social marketing among the action strategies. The aim of this study is to evaluate the impact of social marketing strategies used in an intervention program in trades of food to promote healthy eating in a population of low socioeconomic status resident in the urban area of Santos. This is a quasi-experimental prospective study to compare data before and after the intervention of two groups of trades food, intervention group (n = 8) and a control (n = 8). In each store we will assess socioeconomic characteristics and household food purchases profile in 10 consumers, through interviews, completing a sample of n = 160 individuals in total. The study will consist of three stages: formative research; implementation of the intervention; evaluation of the impact of social marketing intervention in the acquisition of food. Changes in food purchasing profile will be evaluated by calculating the differences between the pre- and post-intervention and the comparison of the difference between the intervention and control groups. The effect of exposure to the actions of social marketing on the impact the intervention will be evaluated by multiple linear regression analysis of changes in food purchasing score, comparing the group (intervention and control) and will be marked by different variables that will measure the exposure (obtained from the evaluation procedure and IEQ), and demographic variables. Exposure variables (scores combining reach, dose and dose received and offered exposure frequency variables of the shares). All analyzes use Statistical Package for Social Sciences ® (SPSS), with the significance level of 0.05. (AU)
