Food Insecurity Interventions to Improve Blood Pressure

When designing a food insecurity intervention to improve blood pressure, does a food subsidy lead to better control than a food box; does the offer of lifestyle counseling improve outcomes relative to not offering lifestyle counseling; and does longer duration of intervention improve outcomes relative to shorter duration?In this randomized comparative effectiveness trial including 458 participants, a food subsidy produced better blood pressure control than a delivered food box. Offering lifestyle counseling and a longer benefit duration did not produce better blood pressure outcomes.A food subsidy improved blood pressure control compared with a food box, but offering lifestyle counseling or longer intervention duration did not lead to better outcomes.
