Despite the hundreds of diet apps available for use on smartphones (mobile phones), no studies have examined their use as tools for dietary assessment and tracking in sports nutrition.
The aim is to examine the prevalence and perceptions of using smartphone diet apps for dietary assessment and tracking among sports dietitians.
A cross-sectional online survey to examine the use and perception of diet apps was developed and distributed to sports dietitians in Australia, Canada, New Zealand, the United Kingdom, and the United States (US).
The overall response rate from the 1709 sports dietitians invited to participate was 10.3% (n=180). diet apps were used by 32.4% (57/176) of sports dietitians to assess and track the dietary intake of athletes. Sports dietitians from the US were more likely to use smartphone diet apps than sports dietitians from other countries (OR=5.61, 95% CI 1.84-17.08, P=.002). Sports dietitians used 28 different diet apps, with 56% (32/57) choosing MyFitnessPal. Overall, sports dietitians held a positive perception of smartphone diet apps, with the majority of respondents viewing diet apps as "better" (25/53, 47%) or "equivalent" (22/53, 41%) when compared with traditional dietary assessment methods.
Nearly one-third of sports dietitians used mobile phone diet apps in sports nutrition practice, and viewed them as useful in helping to assess and track the dietary intake of athletes.
尽管智能手机（移动电话）上有数百种饮食应用程序可供使用，但尚无研究检查它们作为运动营养饮食评估和跟踪工具的使用情况。
本研究旨在检查运动营养师使用智能手机饮食应用程序进行饮食评估和跟踪的流行情况和看法。
开发了一项横断面在线调查，以检查饮食应用程序的使用情况和看法，并分发给澳大利亚、加拿大、新西兰、英国和美国（美国）的运动营养师。
从邀请参加的 1709 名运动营养师中，总体回复率为 10.3%（n=180）。有 32.4%（57/176）的运动营养师使用饮食应用程序来评估和跟踪运动员的饮食摄入量。与来自其他国家的运动营养师相比，来自美国的运动营养师更有可能使用智能手机饮食应用程序（OR=5.61，95%CI 1.84-17.08，P=.002）。运动营养师使用了 28 种不同的饮食应用程序，其中 56%（32/57）选择了 MyFitnessPal。总体而言，运动营养师对智能手机饮食应用程序的看法较为积极，大多数受访者认为饮食应用程序“更好”（25/53，47%）或“等效”（22/53，41%）与传统的饮食评估方法相比。
近三分之一的运动营养师在运动营养实践中使用移动电话饮食应用程序，他们认为这些应用程序有助于评估和跟踪运动员的饮食摄入量。
