SHELf tested the impact of individual (skill-building), environmental (20&nbsp;% price reductions), and combined (skill-building&thinsp;+&thinsp;20&nbsp;% price reductions) interventions on women&#039;s purchasing and consumption of fruits, vegetables, low-calorie carbonated beverages and water. This process evaluation investigated the reach, effectiveness, implementation, and maintenance of the SHELf interventions.<\/p>\n<p style=\"text-align:justify\"><strong>METHODS<\/strong><br \/>\nRE-AIM provided a conceptual framework to examine the processes underlying the impact of the interventions using data from participant surveys and objective sales data collected at baseline, post-intervention (3&nbsp;months) and 6-months post-intervention. Fisher&#039;s exact, &chi; (2) and t-tests assessed differences in quantitative survey responses among groups. Adjusted linear regression examined the impact of self-reported intervention dose on food purchasing and consumption outcomes. Thematic analysis identified key themes within qualitative survey responses.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nReach of the SHELf interventions to disadvantaged groups, and beyond study participants themselves, was moderate. Just over one-third of intervention participants indicated that the interventions were effective in changing the way they bought, cooked or consumed food (p&thinsp;&lt;&thinsp;0.001 compared to control), with no differences among intervention groups. Improvements in purchasing and consumption outcomes were greatest among those who received a higher intervention dose. Most notably, participants who said they accessed price reductions on fruits and vegetables purchased (519&nbsp;g\/week) and consumed (0.5 servings\/day) more vegetables. The majority of participants said they accessed (82&nbsp;%) and appreciated discounts on fruits and vegetables, while there was limited use (40&nbsp;%) and appreciation of discounts on low-calorie carbonated beverages and water. Overall reported satisfaction with, use, and impact of the skill-building resources was moderate. Maintenance of newly acquired behaviours was limited, with less than half of participants making changes or using study-provided resources during the 6-month post-intervention period.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nSHELf&#039;s reach and perceived effectiveness were moderate. The interventions were more effective among those reporting greater engagement with them (an implementation-related construct). Maintenance of newly acquired behaviours proved challenging.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-21701","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Centre for Physical Activity and
