The 2nd edition of the Physical Activity Guidelines for Americans was released in November of 2018. This document contained specific guidelines for young children, children and adolescents, adults, older adults, pregnant and postpartum women, and adults living with chronic conditions and disabilities as well as safety recommendations. Given the complexity of the recommendations, the aim of this study was to assess which of the guidelines were covered by both print and broadcast media in the three months following the release of the guidelines. LexisNexis was searched for print media as well as transcripts of broadcast media. YouTube was used to search for broadcast television news stories. All retrieved stories (n = 34) were coded independently by two raters on which of the elements of the guidelines were covered. On average, stories covered less than half of the guidelines. Most stories reported aerobic guidelines for adults, children and adolescents and young children. Muscle strengthening and vigorous exercise were covered less frequently. No stories mentioned guidelines for pregnant or postpartum women or adults with disabilities. Print (M = 6.4, sd = 2.7) covered more recommendations than broadcast media (M = 4.0, sd = 1.9, p < .01). Coordinated national efforts are needed to ensure that Americans are aware of the new and complete guidelines.
《美国人身体活动指南》第二版于2018年11月发布。该文件包含针对幼儿、儿童和青少年、成年人、老年人、孕妇和产后妇女以及患有慢性病和残疾的成年人的具体指南以及安全建议。鉴于这些建议的复杂性，本研究的目的是评估在指南发布后的三个月内，印刷媒体和广播媒体涵盖了哪些指南内容。利用LexisNexis搜索印刷媒体以及广播媒体的文字记录。使用YouTube搜索广播电视新闻报道。两名评分者对所有检索到的报道（n = 34）独立进行编码，以确定报道涵盖了指南的哪些要素。平均而言，报道涵盖的指南内容不到一半。大多数报道提及了针对成年人、儿童和青少年以及幼儿的有氧活动指南。肌肉强化和剧烈运动的报道较少。没有报道提及针对孕妇或产后妇女或残疾成年人的指南。印刷媒体（M = 6.4，标准差 = 2.7）涵盖的建议比广播媒体（M = 4.0，标准差 = 1.9，p < .01）更多。需要全国性的协调努力，以确保美国人了解这些新的完整指南。
