To estimate the proportion of adults' and parents' knowledge of the adult aerobic and youth physical activity guidelines, respectively, in the United States.
Data were analyzed from a national sample of adults in the 2017 ConsumerStyles survey. Prevalence of knowledge of the adult aerobic guideline (ie, 150 min/wk of moderate-intensity activity) was estimated among all respondents (n = 3910) and of the youth guideline (ie, 60 min/d of physical activity on 7 d/wk) among parents (n = 1288). Odds ratios were estimated using logistic regression models adjusting for demographic characteristics.
Overall, 2.5% (95% confidence interval, 2.0-3.1) of adults and 23.0% (95% confidence interval, 20.5-25.7) of parents were knowledgeable of the adult aerobic and youth guidelines, respectively. After adjustment, odds of knowledge of the adult guideline differed significantly by sex and physical activity level, whereas knowledge of the youth guideline differed by parental education level.
Despite the release of the 2008 Physical Activity Guidelines for Americans nearly a decade ago, most US adults and parents lack knowledge of the adult aerobic and youth physical activity guidelines. Effective communication strategies may help raise awareness of current and future editions of national guidelines for physical activity.
评估美国成年人和父母分别了解成人有氧运动和青少年身体活动指南的比例。
对来自 2017 年消费者风格调查的全国性成年人样本数据进行分析。在所有受访者（n=3910）中估计了对成人有氧运动指南（即每周进行 150 分钟中等强度活动）的知晓率，在父母（n=1288）中估计了对青少年指南（即每周 7 天每天进行 60 分钟的身体活动）的知晓率。使用逻辑回归模型调整人口统计学特征后，估计了比值比。
总体而言，分别有 2.5%（95%置信区间，2.0-3.1）的成年人和 23.0%（95%置信区间，20.5-25.7）的父母了解成人有氧运动和青少年指南。调整后，对成人指南的了解程度因性别和身体活动水平而异，而对青少年指南的了解程度则因父母的教育程度而异。
尽管近十年前发布了 2008 年美国人身体活动指南，但大多数美国成年人和父母都不了解成人有氧运动和青少年身体活动指南。有效的沟通策略可能有助于提高对当前和未来版美国身体活动指南的认识。
