To identify the prevalence of knowledge of the current UK physical activity guidelines which were introduced in 2011 and prior physical activity guidelines (30 min on 5 days each week) within two large samples of UK adult's. To investigate whether knowledge of physical activity guidelines differs according to demographics such as ethnicity, age, education and employment status.
Descriptive cross-sectional study comparing two distinctive adult samples.
National survey and online-administered survey conducted in England.
The 2007 Health Survey for England provides data on knowledge of physical activity guidelines from 2860 UK adults (56% women, 89% white, 63% under 45 years old). In 2013, an online survey was disseminated and data were collected from 1797 UK adults on knowledge of the most recent physical activity guidelines. The 2013 sample was 70% women, 92% white and 57% under 45 years old. All adults in both samples were >18 years old and without illnesses/disorders likely to restrict physical activity.
Knowledge of physical activity guidelines in 2007 and 2013. Demographic correlates of knowledge of moderate-to-vigorous physical activity guidelines.
18% of the 2013 sample accurately recalled the current physical activity guidelines compared with 11% of the 2007 sample who accurately recalled the previous guidelines. The differences in knowledge of physical activity guidelines existed for marital status, gender, age, education and employment status within both 2007 and 2013 samples (p<0.05). Men with lower education and employment status (unemployed including student and retired) and older adults were less likely to know physical activity guidelines (p<0.05). Knowledge of physical activity guidelines remained higher in the 2013 sample after controlling for demographic differences (p<0.05).
Disadvantaged population groups are less knowledgeable about physical activity guidelines. Although knowledge of physical activity guidelines appears to have increased in recent years demographic disparities are still evident. Efforts are needed to promote health information among these groups.
在两个大型英国成年人样本中，确定对 2011 年引入的现行英国体育活动指南和之前的体育活动指南（每周 5 天，每天 30 分钟）的知识普及率。调查根据人口统计学因素（如种族、年龄、教育和就业状况），体育活动指南的知识是否存在差异。
比较两个不同成年样本的描述性横断面研究。
在英格兰进行的全国性调查和在线管理调查。
2007 年英国健康调查提供了 2860 名英国成年人（56%为女性，89%为白人，63%年龄在 45 岁以下）对体育活动指南知识的相关数据。2013 年，进行了在线调查，从 1797 名英国成年人那里收集了对最新体育活动指南知识的相关数据。2013 年的样本中，70%为女性，92%为白人，57%年龄在 45 岁以下。两个样本中的所有成年人年龄均超过 18 岁，且无可能限制体力活动的疾病/障碍。
2007 年和 2013 年的体育活动指南知识。体力活动指南知识与人口统计学因素的相关性。
与准确回忆之前指南（11%）的 2007 年样本相比，2013 年样本中只有 18%的人准确回忆了现行体育活动指南。2007 年和 2013 年两个样本中，婚姻状况、性别、年龄、教育和就业状况的体力活动指南知识均存在差异（p<0.05）。受教育程度和就业状况较低的男性（包括学生和退休人员在内的失业者）和老年人不太可能了解体力活动指南（p<0.05）。在控制了人口统计学差异后，2013 年样本中体力活动指南的知识仍然较高（p<0.05）。
弱势群体对体力活动指南的了解较少。尽管近年来，体力活动指南的知识似乎有所增加，但人口统计学差异仍然存在。需要努力向这些群体宣传健康信息。
