Previous research suggests that children who experience asthma may be less physically active; however, results have been inconclusive. This study aimed to investigate whether the presence of asthma or wheeze is associated with lower physical activity levels in children, and whether sex, body mass index or earlier asthma or wheeze status modifies the association.
This study was conducted in 391 HealthNuts participants in Melbourne, Australia. Asthma and wheeze data were collected via questionnaire at age 4 and 6, and physical activity was measured through accelerometry. Using adjusted linear regression models, the cross-sectional and longitudinal associations were investigated.
There was no evidence of a difference in time spent in moderate-to-vigorous physical activity (MVPA) at age 6 years between children with and without asthma at age 4; children with asthma spent 8.3 minutes more time physically active per day (95% CI: -5.6, 22.1, P = .24) than children without asthma. Similar results were seen for children with current wheeze (5.8 minutes per day more, 95% CI: -5.9, 17.5, P = .33) or ever wheeze or asthma (7.7 minutes per day more, 95% CI: -4.8, 20.2, P = .23) at age 4 years. Comparable null results were observed in the cross-sectional analyses. Interaction with BMI could not be assessed; however, previous asthma or wheeze status and sex were not found to modify these associations.
This analysis found no evidence of asthma hindering physical activity in these young children. These results are encouraging, as they indicate that the Australian asthma and physical activity public health campaigns are being effectively communicated and adopted by the public.
先前的研究表明，患有哮喘的儿童可能身体活动量较少；然而，结果并不明确。本研究旨在调查儿童哮喘或喘息的存在是否与较低的身体活动水平相关，以及性别、体重指数或早期哮喘或喘息状况是否会改变这种关联。
本研究在澳大利亚墨尔本的 391 名 HealthNuts 参与者中进行。在 4 岁和 6 岁时通过问卷调查收集哮喘和喘息数据，并通过加速度计测量身体活动。使用调整后的线性回归模型，研究了横断面和纵向关联。
在 6 岁时，患有哮喘的儿童与没有哮喘的儿童在中度到剧烈体力活动（MVPA）时间上没有差异；患有哮喘的儿童每天多进行 8.3 分钟的身体活动（95%CI：-5.6，22.1，P=0.24）。对于当前喘息（每天多 5.8 分钟，95%CI：-5.9，17.5，P=0.33）或既往喘息或哮喘（每天多 7.7 分钟，95%CI：-4.8，20.2，P=0.23）的儿童也观察到类似的结果。在横断面分析中也观察到了类似的无效结果。无法评估与 BMI 的交互作用；然而，没有发现先前的哮喘或喘息状况和性别会改变这些关联。
本分析未发现哮喘会阻碍这些幼儿的身体活动。这些结果令人鼓舞，因为它们表明澳大利亚的哮喘和身体活动公共卫生运动正被公众有效地传播和采用。
