Having TVs, cars and computers been associated with elevated rates of obesity and diabetes in low-and middle-income .
Although we found no trend between devices occurring in households and obesity or diabetes in countries with high income, we noticed a strong relationship in the case of falling income. Relationship was most pronounced in countries with low income, where the prevalence of obesity increased from 3.4% in the absence of facilities to 14.5% for the three devices. The incidence of diabetes also increased (in the absence of it amounted to 4.7%, and 3 devices already reached 11.7%) – says Dr. Scott Lear of Simon Fraser University. Relations with countries with higher average and lower middle-income countries adopt intermediate values ??between the countries of high and low risk.
international team analyzed data from 107,599 adults 153.996 households from 17 countries who took part in the study Prospective Urban Rural Epidemiology.
Among high-income countries were Canada, Sweden and the United Arab Emirates. Category higher average income represented Argentina, Brazil, Chile, Malaysia, South Africa, Turkey and Poland, and a lower average China, Colombia and Iran. For low-income countries included Bangladesh, India, Pakistan and Zimbabwe.
Volunteers were asked about physical activity, time spent on the seat and diet, as well as whether they have a TV, computer or car, and diabetes. In addition, they were measured and weighed.
Frequently owned device was the TV. In 78% of households has performed at least one receiver. Interest for computers and cars were, respectively, 34 and 32%. Compared to people in rural areas in countries of low and middle-income countries, the people of the towns had more devices. In low-income countries being the owner of all three taken into account the devices associated with a 31% decrease in physical activity, 21% of the rise time of the seat and waist circumference enlargement of 9 cm (compared to those without any devices).
The authors of the letter Canadian Medical Association Journal (CMAJ) suspect that there was no association of countries with high income, because a negative impact on the health of devices already revealed and reflected in the high rates of obesity and type 2 diabetes
