A study conducted on 200 thousand European women showed that doing housework is more likely to protect women from breast cancer than an intensive fitness activities.
The results of this study have been published in the journal Cancer Epidemiology Biomarkers & Prevention.
This research was funded by Cancer Research UK and led by Petra Lahmann of the Department of Epidemiology, Germany Institute of Human Nutrition Potsdam-Rehbrucke, in Nuthetal, Germany and is a team of international researchers.
Petra Lahmann and colleagues used data on more than 200,000 premenopausal women and postmenopausal women aged between 20-80 years from nine European countries.
These researchers use statistical regression model that works is equivalent to the level of metabolic various forms of exercise that has done a woman, so that researchers can compare the value of physical activity against a form of exercise.
Researchers are also taking into account demographic, social and health factors such as age, age at first menstruation, body mass index, education, geographic location, alcohol consumption, age of first pregnancy, oral contraceptives and hormone replacement therapy.
Physical activity women are classified into three groups, namely recreation, household activities and professional work. The total amount of physical activity is also taken into account. This research continued until 6.4 years and found 3423 invasive breast cancers occur in groups.
Results showed that total physical activity reduces breast cancer risk only in postmenopausal women.
But perhaps more surprising, as quoted by Medicalnewstoday, Thursday (08/05/2010), domestic work was to reduce the risk of both premenopausal breast cancer (19 percent) and postmenopausal women (29 percent).
The participants spent an average of 16-17 hours per week to do tuga-job households, such as washing, cooking and cleaning house.
While this study found no significant relationship between breast cancer risk reduction with recreational activities or physical activity associated with the job.
