Adherence and Body Weight with Daily Avocado Consumption Among Latina Women of the Habitual Diet and Avocado Trial (HAT)

Objectives: The aim of this study was to examine the adherence, changes in weight, and, waist circumference associated with the daily consumption of a culturally preferred food, namely an avocado, among Hispanic/Latina females in the Habitual Diet and Avocado Trial (HAT). Methods: HAT was a multisite, randomized controlled trial conducted between 2018 and 2020. Participants in the Avocado-Supplemented Diet Group were provided with and instructed to consume one avocado/day (~2.2 servings) for 6 months; participants in the Habitual Diet Group were instructed to follow their usual diet and limit intake to ≤2 avocados/month. Avocado consumption was assessed using three random 24 h dietary recalls administered by dietitians. This analysis focused on women who self-identified as Hispanic/Latina. Results: Within HAT, 158 females self-identified as Hispanic/Latina (median age: 42 years, IQR: 36–54). Across the dietary recalls, the Avocado-Supplemented Group (n = 80) consumed 1.9–2.1 avocado servings/day; the Habitual Diet Group (n = 78) consumed 0.04–0.09 servings/day (p < 0.001). The weight and waist circumference measurements were similar between groups. Hispanic/Latina females remained adherent to daily avocado consumption for the 6-month study period, without a significant change in their body weight or waist circumference measurements. Conclusions: Integrating a culturally preferred food into a dietary intervention enhanced adherence amongst Latina adults, with no impact significant impact on body composition.
