Recently, the internationally renowned medical magazine "American Medical Association," published a large prospective cardiovascular study, the results showed that the level of physical activity and the risk of cardiovascular events is negatively correlated.
The study was jointly conducted by the University of Oxford, Peking University and the Chinese Academy of Medical Sciences. A total of 487,334 subjects from 10 regions (5 cities and 5 rural areas) in China from 2004 to 2008 were selected and no history of cardiovascular disease , Subjects were between the ages of 30 and 79 years (mean, 51 years). The researchers tracked the subject's health through hospital records and death reports while assessing occupations based on MET-h / d And non-occupational physical activity, the analysis of the relationship between cardiovascular events and physical activity, physical activity including occupational physical activity, physical exercise and housework.
Metabolic equivalence is an important indicator of relative energy metabolism and exercise intensity, and is a common indicator of relative energy metabolism for various activities based on quiet and sitting energy expenditure.
The results showed that the average activity of all subjects was 21.5 MET-h / d, and mainly from occupational activities (especially men), and the level of physical activity was negatively correlated with the risk of major vascular events.For the follow-up of 7.5 years A total of 36,184 subjects had new vascular events, of which 5082 had coronary disease, 25 647 had ischemic stroke, 5252 had hemorrhagic stroke, and 8437 died of cardiovascular disease.
Throughout the study, a 4 MET-h / d rise in physical activity levels (equivalent to about 1 hour a day) reduced the risk of developing 6% of major cardiovascular events (95% CI, 5% -7%) , Of which the risk of total death from coronary heart disease, stroke and cardiovascular disease can be reduced by 9%, 6% and 12%, respectively, and the benefits of such physical activity are irrespective of regions and men and women. However, in hypertensive patients However, in professional sports activities, the average level of daily physical activity is over 20 MET-h / d, and the association between physical activity level and cardiovascular risk is greatly weakened, especially intracerebral hemorrhage.
Of course, a large number of studies show that people who exercise more than half an hour every day can help prevent heart disease and death from being exhausted if they go to the gym to exercise regularly, and if there is no time, It can only rely on daily walking, walking, housework and other activities to ensure daily activity.
However, doing housework is really a good choice.
Housework not only reduces the risk of cardiovascular events, but also reduces all-cause and cancer mortality. In 2016, a sudden publication of a dissertation on China's social networking platform was published in the journal PLos One, and studies show that housework can reduce all-cause and cancer deaths among Chinese men.
The study further distinguished heavy household and light housework by categorizing heavy household duties as vacuuming, wiping floors, mopping floors, scrubbing windows, car washing, moving furniture, moving gas cylinders, etc. Dusting, dishwashing, hand washing, ironing Hot, dry clothes, cooking, buy daily necessities classified as light housework.
The study enrolled 2,867 subjects. To ensure the independence of household chores and mortality, the researchers analyzed age, educational attainment, socioeconomic status of self-assessment, total energy intake, smoking, drinking, BMI, residency Conditions and leisure time exercise level and other factors were corrected.The study showed that all housework on men have all the benefits of reducing all-cause mortality and cancer mortality, but the benefits of different sizes.But for women, heavy housework To increase all-cause mortality, light and heavy household tasks work together to increase cancer deaths.
