Abstract：
UNASSIGNED: Adolescent nutrition has faced a policy neglect, partly owing to the gaps in dietary intake data for this age group. The Food Recognition Assistance and Nudging Insights (FRANI) is a smartphone application validated for dietary assessment and to influence users toward healthy food choices.
UNASSIGNED: This study aimed to assess the feasibility (adherence, acceptability, and usability) of FRANI and its effects on food choices and diet quality in female adolescents in Vietnam.
UNASSIGNED: Adolescents (N = 36) were randomly selected from a public school and allocated into 2 groups. The control group received smartphones with a version of FRANI limited to dietary assessment, whereas the intervention received smartphones with gamified FRANI. After the first 4 wk, both groups used gamified FRANI for further 2 wk. The primary outcome was the feasibility of using FRANI as measured by adherence (the proportion of completed food records), acceptability and usability (the proportion of participants who considered FRANI acceptable and usable according to answers of a Likert questionnaire). Secondary outcomes included the percentage of meals recorded, the Minimum Dietary Diversity for Women (MDDW) and the Eat-Lancet Diet Score (ELDS). Dietary diversity is important for dietary quality, and sustainable healthy diets are important to reduce carbon emissions. Poisson regression models were used to estimate the effect of gamified FRANI on the MDDW and ELDS.
UNASSIGNED: Adherence to the application was 82% and the percentage of meals recorded was 97%. Acceptability and usability were 97%. MDDW in the intervention group was 1.07 points (95% CI: 0.98, 1.18; P = 0.13) greater than that in the control (constant = 4.68); however, the difference was not statistically significant. Moreover, ELDS in the intervention was 1.09 (95% CI: 1.01, 1.18; P = 0.03) points greater than in the control (constant = 3.67).
UNASSIGNED: FRANI was feasible and may be effective to influence users toward healthy food choices. Research is needed for FRANI in different contexts and at scale.The trial was registered at the International Standard Randomized Controlled Trial Number as ISRCTN 10681553.

摘要：
■青少年营养面临政策忽视，部分原因是该年龄组的饮食摄入量数据存在差距。FoodRecognitionAssistanceandNudgingInsights（FRANI）是一款经过验证的智能手机应用程序，可用于饮食评估并影响用户选择健康的食物。
■本研究旨在评估可行性(坚持，可接受性,和可用性）的FRANI及其对越南女性青少年的食物选择和饮食质量的影响。
■从一所公立学校随机选择青少年（N=36），并将其分为两组。对照组接受了FRANI版本的智能手机，仅限于饮食评估，而干预接受了带有游戏化FRANI的智能手机。在前4周之后，两组均使用游戏化FRANI治疗2周.主要结果是通过依从性（完成的食物记录的比例）来衡量使用FRANI的可行性，可接受性和可用性（根据Likert问卷的回答，认为FRANI可接受和可用的参与者比例）。次要结果包括记录的膳食百分比，女性最低膳食多样性(MDDW)和饮食柳叶刀评分(ELDS)。饮食多样性对饮食质量很重要，可持续的健康饮食对减少碳排放很重要。使用泊松回归模型来估计游戏化FRANI对MDDW和ELDS的影响。
■对应用的依从性为82％，记录的进餐百分比为97％。可接受性和可用性为97%。干预组的MDDW比对照组(常数=4.68)大1.07分(95%CI:0.98,1.18;P=0.13);差异无统计学意义。此外，干预中的ELDS比对照组（常数=3.67）高1.09点（95％CI：1.01，1.18；P=0.03）。
■FRANI是可行的，并且可能有效地影响用户选择健康的食物。FRANI需要在不同的背景和规模上进行研究。该试验在国际标准随机对照试验编号中注册为ISRCTN10681553。
