Recent lifestyle approaches to physical activity have included the promotion of domestic physical activities such as do-it-yourself or home maintenance, gardening and housework. Although it is acknowledged that any activity is better than none, there is a danger that those undertaking domestic 'chores' may assume that this activity is moderate intensity and therefore counts towards this 150 minute per week target The purpose of this paper was to report the contribution domestic physical activity makes to total weekly physical activity and the relationship between domestic physical activity and leanness in the Northern Ireland population.
4563 adults participated in this cross-sectional survey of physical activity behaviour. Data were collected through face-to-face interviews using computer assisted personal interviewing. Gender and age group differences in domestic MVPA activity and the ratio of domestic to total MVPA were explored using non-parametric Kruskal-Wallis tests. Self-reported volume and intensity of physical activity (in bouts of 10 minutes or more) in the home and self-reported height and weight were used to determine the association between domestic physical activity and leanness using an ANCOVA having controlled for age, gender, socio-economic and smoking status.
42.7% of the population report levels of physical activity which meet or exceed the current United Kingdom recommendations. Domestic physical activity accounts for 35.6% of the reported moderate to vigorous physical activity (MVPA). For women, if domestic physical activity was excluded from total MVPA, only 20.4% would be deemed to meet current recommendations. Time spent in domestic physical activity at moderate or vigorous intensity was found to be negatively associated with leanness (P = 0.024), [R Squared = .132 (Adjusted R Squared = .125)].
Domestic physical activity accounts for a significant proportion of self-reported daily MVPA particularly among females and older adults however such activity is negatively associated with leanness suggesting that this activity may not be sufficient to provide all of the benefits normally associated with meeting the physical activity guidelines.
近期针对身体活动的生活方式方法包括推广诸如自己动手做或家庭维护、园艺和家务等家庭身体活动。尽管人们承认任何活动都比不活动要好，但存在这样一种风险，即从事家庭“杂务”的人可能会认为这种活动是中等强度的，因此可计入每周150分钟的目标。本文的目的是报告家庭身体活动对每周总身体活动的贡献以及北爱尔兰人群中家庭身体活动与瘦体重之间的关系。
4563名成年人参与了这项身体活动行为的横断面调查。通过使用计算机辅助个人访谈的面对面访谈收集数据。使用非参数Kruskal-Wallis检验探索家庭中等至剧烈身体活动（MVPA）中的性别和年龄组差异以及家庭MVPA与总MVPA的比率。在家中自我报告的身体活动量和强度（以10分钟或更长时间的时间段计）以及自我报告的身高和体重用于通过控制年龄、性别、社会经济和吸烟状况的协方差分析来确定家庭身体活动与瘦体重之间的关联。
42.7%的人群报告的身体活动水平达到或超过了当前英国的建议。家庭身体活动占报告的中等至剧烈身体活动（MVPA）的35.6%。对于女性而言，如果将家庭身体活动排除在总MVPA之外，只有20.4%的女性会被认为达到当前建议。发现以中等或剧烈强度进行家庭身体活动所花费的时间与瘦体重呈负相关（P = 0.024），[决定系数 = 0.132（调整后决定系数 = 0.125）]。
家庭身体活动在自我报告的每日MVPA中占很大比例，尤其是在女性和老年人中，然而这种活动与瘦体重呈负相关，这表明这种活动可能不足以提供通常与达到身体活动指南相关的所有益处。
