The obesity and diabetes epidemic is spreading to parts of the world where historically the problem has been less pronounced, a new study finds, and it is linked to increased TV, car and computer ownership.
The study, published in the Canadian Medical Association Journal, looked at obesity and Type 2 diabetes in households in "low income" countries, like Bangladesh, Zimbabwe, Pakistan and India; "middle income" countries, like Argentina and China; and "high income" countries, like Canada and Sweden. Participants were asked if they owned a car, a TV or a computer. They were also asked about their diets and level of physical activity, and their measurements and weight were recorded. More than 100,000 households participated.
What the study found was that as households in the lower income countries added televisions, cars and other modern conveniences, obesity rates more than quadrupled, and rates of Type 2 diabetes more than doubled. In the higher income countries, the difference was only marginal, presumably, the researchers said, because the negative impact from the modern day devices had already occurred.
