許多人把做家務(wù)當成鍛煉身體,，但英國一項最新調(diào)查顯示,，做家務(wù)較多者反而更容易超重。研究人員認為,，這是由于多數(shù)人會高估做家務(wù)的運動量,，從而忽視身體鍛煉。
英國北愛爾蘭大學(xué)研究人員在新一期《BMC公共衛(wèi)生》上報告說,，他們對4563名成年人的身體鍛煉,、做家務(wù)習慣及體重等狀況進行了調(diào)查，并詢問了他們?nèi)绾卧u價做家務(wù)的勞動強度等問題,。結(jié)果顯示,，婦女和中老年人做家務(wù)較多，也更傾向于把做家務(wù)歸為他們“中度到劇烈運動的重要組成部分”,。然而,，這一人群中身體超重的比例也較高。
領(lǐng)導(dǎo)這項研究的瑪麗·墨菲教授說,，“我們發(fā)現(xiàn)做家務(wù)的多少與超重風險成正相關(guān),，這并不意味著做家務(wù)不利于身體健康，而可能是因為人們往往高估做家務(wù)的運動量,。”
英格蘭公共衛(wèi)生局專家凱文·芬頓指出,，健康建議是，每周至少進行150分鐘中等強度的身體鍛煉,，包括快走,、健身等，但這項研究結(jié)果再次表明,，多數(shù)人傾向于高估自己的運動量,。（生物谷Bioon.com)

Does doing housework keep you healthy,？ The contribution of domestic physical activity to meeting current recommendations for health
Marie H Murphy， Paul Donnelly,， Gavin Breslin,， Simon Shibli and Alan M Nevill
Background
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.
Methods
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.
Results
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)].
Conclusions
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.
