Determining Nutritional Barriers to Access to Fresh Fruits, Vegetables, and Whole Grains in Older Americans

Abstract

The University of the District of Columbia is a partner of the Northeast Hatch Multistate Research Collaborative. This research project, known as the UDC NE 1439, was designed as a pilot study to determine the barriers that prevented the consumption of fresh fruits, vegetables, and whole grains among older adults in Wards 5, 7, and 8 in the District of Columbia (DC). The residents of these wards have been shown to have higher rates of chronic diseases. Data shows that Ward 7 has the highest rate of deaths due to diabetes. Furthermore, Wards 5, 7, and 8 have the highest percentage of hypertension and diabetes This project used a quantitative and qualitative survey instrument, which included 53 questions and/or statements using a Likert scale: demographics (8 questions); household information (2 questions); shopping habits (8 questions); eating habits, including the identity of the person who prepared meals in the home (21 questions); physical fitness (11 questions); and policy (3 questions). Ninety-six (96) older adults participated in the survey, with a gender distribution of 77% female (68 individuals), 22% male (24 individuals), and 1% not reported (1 individual). The racial distribution of the participants was 91% (87) African American, .01% (one) Asian American, .01% (one) Caucasian, .01% (one) Native American, and .03% (three) others/not reported. Additionally, according to the participants’ residency results, Ward 5 accounted for 23% of the participants (24 participants), Ward 7 for 38% (33 participants), and Ward 8 for 38% (33 participants). The participants’ average age was ≥ 56, (45 to 76 and over) and most were the primary financial supporters of their households and the primary grocery shoppers in their families. In conclusion, this project determined that access to fresh fruits and vegetables and travel time to a full-service grocer were less prominent barriers; this was an unexpected finding. Though the participants indicated sufficient access to fresh fruits, vegetables, and whole grains, they lacked nutrition-based knowledge. Many of them viewed unfitting food choices as healthy. An intervention centered on nutrition education using food demonstrations and grocer tours would improve nutrition knowledge in this population. This offered these nutrition and dietetics research assistants with an opportunity to provide nutrition education to the population in question. Moreover, it presents an opportunity to extend nutrition education to all seniors across the Washington, DC region.
