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). 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. Within HAT, 158 females self-identified as Hispanic/Latina (median age: 42 years, IQR: 36-54). Across the dietary recalls, the Avocado-Supplemented Group ( = 80) consumed 1.9-2.1 avocado servings/day; the Habitual Diet Group ( = 78) consumed 0.04-0.09 servings/day ( < 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. Integrating a culturally preferred food into a dietary intervention enhanced adherence amongst Latina adults, with no impact significant impact on body composition.
本研究的目的是在“习惯饮食与牛油果试验”（HAT）中，调查西班牙裔/拉丁裔女性每日食用一种符合其文化偏好的食物（即牛油果）与依从性、体重变化和腰围之间的关系。HAT是一项在2018年至2020年期间进行的多中心随机对照试验。牛油果补充饮食组的参与者被提供并被指导每天食用一个牛油果（约2.2份），持续6个月；习惯饮食组的参与者被指导遵循其通常的饮食，并将摄入量限制在每月≤2个牛油果。牛油果的摄入量通过由营养师进行的三次随机24小时饮食回顾来评估。本分析聚焦于自我认定为西班牙裔/拉丁裔的女性。在HAT中，有158名女性自我认定为西班牙裔/拉丁裔（中位年龄：42岁，四分位间距：36 - 54岁）。在整个饮食回顾中，牛油果补充组（n = 80）每天食用1.9 - 2.1份牛油果；习惯饮食组（n = 78）每天食用0.04 - 0.09份（P < 0.001）。两组之间的体重和腰围测量结果相似。在为期6个月的研究期间，西班牙裔/拉丁裔女性坚持每日食用牛油果，其体重和腰围测量结果没有显著变化。将一种符合文化偏好的食物纳入饮食干预可提高拉丁裔成年人的依从性，且对身体成分没有显著影响。
