Restrictions during the COVID-19 crisis will have impacted on opportunities to be active. We aimed to (a) quantify the impact of COVID-19 restrictions on accelerometer-assessed physical activity and sleep in people with type 2 diabetes and (b) identify predictors of physical activity during COVID-19 restrictions.
Participants were from the UK Chronotype of Patients with type 2 diabetes and Effect on Glycaemic Control (CODEC) observational study. Participants wore an accelerometer on their wrist for 8 days before and during COVID-19 restrictions. Accelerometer outcomes included the following: overall physical activity, moderate-to-vigorous physical activity (MVPA), time spent inactive, days/week with ≥30-minute continuous MVPA and sleep. Predictors of change in physical activity taken pre-COVID included the following: age, sex, ethnicity, body mass index (BMI), socio-economic status and medical history.
In all, 165 participants (age (mean±S.D = 64.2 ± 8.3 years, BMI=31.4 ± 5.4 kg/m , 45% women) were included. During restrictions, overall physical activity was lower by 1.7 mg (~800 steps/day) and inactive time 21.9 minutes/day higher, but time in MVPA and sleep did not statistically significantly change. In contrast, the percentage of people with ≥1 day/week with ≥30-minute continuous MVPA was higher (34% cf. 24%). Consistent predictors of lower physical activity and/or higher inactive time were higher BMI and/or being a woman. Being older and/or from ethnic minorities groups was associated with higher inactive time.
Overall physical activity, but not MVPA, was lower in adults with type 2 diabetes during COVID-19 restrictions. Women and individuals who were heavier, older, inactive and/or from ethnic minority groups were most at risk of lower physical activity during restrictions.
新冠疫情期间的各种限制会对人们的活动机会产生影响。本研究旨在：(a) 量化新冠疫情限制对 2 型糖尿病患者的计步器评估身体活动和睡眠的影响；(b) 确定新冠疫情限制期间身体活动的预测因素。
参与者来自英国 2 型糖尿病患者的昼夜节律和对血糖控制的影响（CODEC）观察性研究。参与者在新冠疫情限制之前和期间佩戴腕部计步器 8 天。计步器的结果包括以下内容：总体身体活动、中等到剧烈的身体活动（MVPA）、不活动时间、每周有≥30 分钟连续 MVPA 的天数和睡眠。新冠疫情前的身体活动变化的预测因素包括：年龄、性别、种族、体重指数（BMI）、社会经济地位和病史。
共纳入 165 名参与者（年龄（平均值±标准差=64.2±8.3 岁，BMI=31.4±5.4kg/m²，45%为女性）。在限制期间，总体身体活动减少了 1.7mg（约 800 步/天），不活动时间增加了 21.9 分钟/天，但 MVPA 和睡眠时间没有统计学上的显著变化。相比之下，每周有≥1 天有≥30 分钟连续 MVPA 的人数比例更高（34%比 24%）。身体活动减少和/或不活动时间增加的一致预测因素是 BMI 较高和/或女性。年龄较大和/或属于少数民族群体与不活动时间较长有关。
在新冠疫情限制期间，2 型糖尿病成年人的总体身体活动（但不是 MVPA）减少。女性和体重较重、年龄较大、不活跃和/或属于少数民族群体的人在限制期间身体活动减少的风险最高。
