Fruit And Vegetable Or Recreation Prescriptions for UW-Madison Students (FAVORx)

Measuring the Feasibility of Fruit and Vegetable or Recreation Prescriptions Among UW-Madison Students

This research will use randomized controlled trial (RCT) methodology to assess the feasibility of a prescription for fruit/vegetable CSA shares or exercise by bikeshare on obesity-related outcomes. Three cohorts of n=10 University of Wisconsin-Madison (UW) students (total 30) will be randomized to three groups: (1) a 10-week fruit and vegetable community supported agriculture (CSA) share prescription program with vegetable education and cooking support from UW Slow Food; (2) a 10-week Madison B-cycle bikeshare membership prescription program with exercise support or (3) a non-interventional wait-list control group. The primary outcome will be change in Body Mass Index (BMI) (a measure of obesity using a person's weight in kilograms divided by his or her height in meters squared). Secondary outcomes will be fasting lipids, blood pressure, and glycated hemoglobin (HGA1c) levels. All of these measures will be tested at baseline and just after the 10-week intervention

Detailed Description

This research will use randomized controlled trial (RCT) methodology to assess the feasibility of a prescription by University Health Services (UHS) Providers for fruit/vegetable CSA shares or exercise by bikeshare on obesity-related outcomes. Three cohorts of n=10 UW-Madison students (total 30) will be randomized to three groups: (1) a 10-week fruit and vegetable community supported agriculture (CSA) share prescription program with vegetable education and cooking support from UW Slow Food; (2) a 10-week Madison B-cycle bikeshare membership prescription program with exercise support from the UHS wellness program; or (3) a non-interventional wait-list control group. The primary outcome will be change in Body Mass Index (a measure of obesity using a person's weight in kilograms divided by his or her height in meters squared). Secondary outcomes will be fasting lipids, blood pressure, and HGA1c levels. All of these measures will be tested at baseline and just after the 10-week intervention. Fasting lipids and HGA1c levels will be assessed through a blood draw. Study participants will be asked to refrain from eating or drinking anything except for water 8-12 hours prior to the blood draw. Study participants will fill out validated questionnaires assessing perceived stress, physical activity levels, self-efficacy, social support, and general mental and physical health at baseline and after the intervention. Study participants will also conduct a 3 day dietary recall before and after the intervention.

Study participants randomized to the "CSA group" will be expected to pick up their weekly CSA box at University Health Services and to commit to using and consuming as much of the produce as they are able. CSA group participants will also be required to attend two cooking and food preparation classes coordinated by Slow Food UW. The classes will teach study participants how to properly clean and prepare the fruits and vegetables from a weekly CSA box, and also offer techniques and show them how to cook the foods in a healthy manner. These classes will also educate study participants on the benefits of eating fruits and vegetables and buying them from local farmers. These two classes will only exist for study participants in this fruit and veggie CSA group. Participants in the "CSA group" will also be required to take a field trip to the farm providing their CSA share, which will offer the opportunity for participants to gain a better understanding of from where their food comes.

Study participants randomized to the "bikeshare group" will be expected to use B-cycle bikeshare bicycles for transportation and/or recreation as much as is safe and appropriate. Bikeshare group participants will be required to attend two bicycle use/safety courses. These courses will introduce the B-cycle program, demonstrate use of the B-cycle station, provide information use of helmets and safety gear, and provide information on the basics of cycling and keeping yourself safe and comfortable while riding a B-cycle bike in traffic. B-cycle usage, including estimated distance traveled and frequency of use, will be tracked via the B-cycle Madison website.

Study participants in the control group will receive continued "usual care" from University Health Services providers, which includes educational brochures on healthy eating and exercising. Control group participants are not part of a wait-list group.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Fruit and Vegetable CSA Prescription; Study participants randomized to the "CSA group" will be expected to pick up their weekly CSA box at University Health Services and to commit to using and consuming as much of the produce as they are able. CSA group participants will also be required to attend two cooking and food preparation classes coordinated by Slow Food UW. The classes will teach study participants how to properly clean and prepare the fruits and vegetables from a weekly CSA box, and also offer techniques and show them how to cook the foods in a healthy manner. These classes will also educate study participants on the benefits of eating fruits and vegetables and buying them from local farmers. These two classes will only exist for study participants in this fruit and veggie CSA group. Participants in the "CSA group" will also be required to take a field trip to the farm providing their CSA share, which will offer the opportunity for participants to gain a better understanding of from where their food comes.	Behavioral: Fruit and Vegetable CSA Prescription; Study Participants will collect and use fruit and vegetable CSA boxes given to them weekly for 10 weeks.
Active Comparator: Bikeshare Prescription; Study participants randomized to the "bikeshare group" will be expected to use B-cycle bikes for transportation and/or recreation as much as is safe and appropriate. Bikeshare group participants will be required to attend one bicycle use/safety course. This course will introduce the B-cycle program, demonstrate use of the B-cycle station, provide information use of helmets and safety gear, and provide information on the basics of cycling and keeping yourself safe and comfortable while riding in traffic. The study participants in this group will also be required to attend a class on the benefits of exercise, including bicycling, among other forms of physical activity. This class will be offered by the University Health Services Wellness program. B-cycle usage, including estimated distance traveled and frequency of use, will be tracked via the B-cycle Madison website.	Behavioral: Bikeshare Prescription; Study participants will use bikeshare for transportation and physical activity for 10 weeks
No Intervention: Control; Study participants in the control group will receive continued "usual care" from University Health Services providers, which includes educational brochures on healthy eating and exercising, plus a cash payment. Control group participants are not part of a wait-list group.
