Food availability as a determinant of weight gain among renal transplant recipients

Abstract

Excessive weight gain is common after renal transplantation, but it is unknown whether environmental factors, such as food availability, contribute to this important clinical problem. We evaluated the effects of food availability (fast food restaurants, convenience stores, and grocery stores within 1, 2, and 3 mile buffers of transplant recipients' residences) on body mass index (BMI) change during the first year post-transplant. Participants (n=299) resided in Memphis, Tennessee. BMI increased by 1.42 units (p<.001) corresponding to an average weight gain of 9.25lbs (5.43%) during the first year post-transplant. The number of grocery stores within 1 mile of recipient's residence was associated with an increase in BMI (p<.05), but fast food restaurants and convenience stores were not significantly associated with BMI change. © 2014 Wiley Periodicals, Inc.
