先前的研究已经确定，儿童时期的身体活动减少，但我们没有足够的信息来说明这些变化在种族群体中的差异。确定种族群体之间是否存在不平等，对于了解是否需要采取不同的干预战略至关重要。我们的目的是确定英国不同种族群体的身体活动如何随着时间的推移而变化。方法：我们使用了解社会，一个全国代表性的英国纵向调查，以跟踪不同种族群体的身体活动随时间的变化。对于10至15岁的儿童，我们探讨了参加体育运动的频率和上学的交通方式。这些因素是在2009年至2015年期间可用的六波中的四波（1，2，4和6）中测量的。孩子们被问到他们每周参加体育活动的频率。关于出行方式，儿童报告了他们是步行、骑自行车、使用公共交通工具、开车还是综合使用这些方式。当包括随访的儿童时，样本量太低，无法按年龄或性别分层。我们使用线性回归来评估种族是否与体育参与和上学交通方式的变化相关。结果在基线时，巴基斯坦儿童的体育参与率最低（6%），通勤率最高（54%）;不同种族儿童上学的交通方式差异有统计学意义（p<0.00）。在第一波和第二波、第一波和第四波以及第一波和第六波之间，所有族裔群体参加体育运动的频率都有所下降。大多数儿童在任何一波之间都没有增加或减少他们上学的交通方式的总体活动水平。大多数群体继续使用积极的方法，但在第一波和第四波之间，50%的巴基斯坦儿童保留了上学的非积极方法。尽管存在一些差异，但线性回归显示，种族与运动参与频率的变化或任何波之间运输方式的变化并不显著相关。结论旨在预防一般人群中儿童体力活动下降的干预措施可能适用于少数民族群体。由于在一些少数民族中，上学的积极出行率仍然很低，仍然需要采取有针对性的干预措施，以初步改变少数民族儿童的通勤模式。
Background Previous research has established that physical activity declines during childhood, but we have inadequate information on how these changes differ by ethnic group. Determining if inequalities exist between ethnic groups is vital for understanding whether different intervention strategies are necessary. We aimed to determine how physical activity has changed over time within different UK ethnic groups. Methods We used Understanding Society, a nationally representative UK-based longitudinal survey to track changes in physical activity over time in different ethnic groups. For children aged 10 to 15, we explored the frequency of participating in sports and mode of travel to school. These factors were measured in four of the available six waves (1, 2 4 and 6), between 2009 and 2015. Children were asked how frequently they participate in sports per week. For mode of travel, children reported whether they walked, cycled, used public transport, were driven or used a combination of these. When including children who were followed up, the sample size was too low to stratify by age or gender. We used linear regression to assess if ethnicity was associated with change in sports participation and mode of transport to school. Results At baseline, low sports participation (6%) and inactive commuting (54%) was highest in Pakistani children; differences were significant between ethnic groups for mode of travel to school (p<0.00). Frequency of sports participation declined for all ethnic groups between waves 1 and 2, 1 and 4 and 1 and 6. The majority of children did not increase or decrease the overall activity level of their mode of transport to school between any of the waves. Most groups continued to use an active method, though between waves 1 and 4, 50% of Pakistani children retained an inactive method of commuting to school. Despite some differences, linear regression showed that ethnicity was not significantly associated with change in frequency of sports participation or change in mode of transport between any of the waves. Conclusion Interventions aimed at preventing the decline of physical activity in children from the general population may be appropriate for ethnic minority groups. As active travel to school remains low in some ethnic minorities, targeted interventions to initially change mode of commuting in ethnic minority children is still needed.
