Rates of obesity and Type Two diabetes are rising in low-income countries, and experts think an increase in luxuries like televisions that keep people sedentary are to blame.
Canadian researchers looked at data on nearly 110,000 households worldwide in low-income countries. They found an increase in obesity and Type Two diabetes correlated with an increase in ownership of televisions, computers and cars.
In low-income countries, owning all three conveniences was associated with a 31% decrease in physical activity and an increase in waist size.
The same effect was not found in high-income countries, but experts think it may be because the negative health consequences of leading sedentary lifestyles have already occurred there.
