Abstract
Purpose
Transportation, access to follow-up care, and association with weight loss are understudied in the bariatric population. The objective of this study was to determine how transportation variables associate with postoperative attendance and weight loss through 24 months.
Materials and Methods
Seven hundred eighty-seven patients (81.3% female; 59.1% White) who had primary surgery (48.6% gastric bypass) from 2015 to 2019 were included. Sidewalk coverage and number of bus stops from patients’ homes, driving distance in miles and minutes from patients’ homes to the nearest bus stop and the clinic were measured. Bivariate analyses were conducted with the transportation variables and attendance and %TWL at 2 or 3, 6, 12, and 24 months. One mixed multilevel model was conducted with dependent variable %TWL over 24 months with visits as the between-subjects factor and covariates: race, insurance, surgical procedure, and driving distance to the clinic in minutes, attendance, and %TWL over 24 months; an interaction between distance, attendance, and visits.
Results
There were no significant differences between the majority of the transportation variables and postoperative attendance or %TWL. Patients who had perfect attendance had improved %TWL at 12 months [t(534)=−1.92, p=0.056] and 24 months [t(393)=−2.69, p=0.008] compared to those who missed at least one appointment. Patients with perfect attendance and who had shorter driving times (under 20 min) to the clinic had greater weight loss through 24 months [F(10, 1607.50)=2.19, p=0.016)].
Conclusions
Overall, transportation factors were not associated with attendance and weight loss, with the exception of the interaction between shorter driving minutes to follow-up and perfect attendance.

Key Points
• There were no significant differences between the majority of the transportation variables and attendance or %TWL at any of the postoperative assessments.
• Patients who had perfect attendance through 24 months had improved %TWL at 12 months and 24 months compared to those who missed at least one appointment.
• Patients with perfect attendance and who had shorter driving times (under 20 min) to the clinic had greater weight loss through 24 months.
• Future research should consider how telemedicine visits may aid patients with greater travel times and more socioeconomic need.
