Barriers and Facilitators to Vegetable Intake

Barriers and Facilitators to Following the Dietary Guidelines for Vegetable Intake: Follow-up of an Intervention to Increase Vegetable Consumption

The purpose of this study is to find out why people do or do not eat vegetables.

Study Overview

• Status: Completed
• Conditions: Overweight; Obese
• Intervention / Treatment: Other: Barriers; Other: Facilitators

Detailed Description

The Dietary Guidelines for Americans (DGA) stress the importance of a diet high in fruits and vegetables (FV) to achieve health benefits. Despite the recommendations, adherence is low; only 12% of the population meets the recommendation for fruits and even less of the population (9%) meets the recommendation for vegetables. Recently, it was found that vegetable consumption increased when individuals were provided the recommended daily amounts while participating in a clinical study, but returned to pre-study low levels when vegetables were no longer supplied. This result suggests that habitual consumption of FV is strongly regulated by behaviors influenced by social, environmental, and/or individual factors. Therefore, identifying regulatory factors of vegetable consumption will greatly assist in developing successful strategies to increase vegetable intake to achieve health benefits. The overall objective of this study is to examine both barriers and facilitators to adherence to consuming DGA-recommended amounts of vegetables in participants who completed a randomized controlled trial with provided vegetables or who were in a control group, using the Nominal Group Technique (NGT).

Eligibility Criteria

• Ages Eligible for Study: 18 years to 65 years (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

• Sampling Method: Non-Probability Sample

Study Population

Recruitment will be limited to contacting participants who previously took part in a study (NCT02585102) and upon completion of that study indicated willingness to be contacted for a follow-up study. The original study recruited overweight or obese adults who reported consuming not more than 1 serving of vegetables per day. In that study, participants were provided vegetables or were in a control group. Research staff will send invitations to participate in one of the NGT sessions.

Description

Inclusion Criteria:

• Participant in NCT02585102 who gave permission to be contacted for a follow-up study.

Exclusion Criteria:

• Did not participate in NCT02585102.
• Participant in NCT02585102 who did not give permission to be contacted for a follow-up study.

Barriers to Vegetable Consumption; Four groups of participants will meet for NGT sessions, identifying barriers to meeting the DGA recommendation for vegetable consumption.	Other: Barriers; NGT sessions identifying barriers to vegetable intake.
Facilitators to Vegetable Consumption; Four groups of participants will meet for NGT sessions, identifying facilitators to meeting the DGA recommendation for vegetable consumption.	Other: Facilitators; NGT sessions identifying facilitators to vegetable intake.
