Rising rural body-mass index is the main driver of the global obesity epidemic

• 2,009 population-based studies
• Measurement of height and weight in over 112 million adults
• Rural and urban place of residence from 1985 to 2017.
• More than 55% of the global rise in mean BMI from 1985 to 2017, and up to 90% in some low-and middle-income regions, was due to increases in BMI in rural areas.
• BMI is rising at the same rate or faster in rural areas than in cities.

Explanation

In high-income countries:

• BMI has been generally higher in rural areas since 1985, especially for women.
• This is due to the disadvantages experienced by those living outside cities: lower income and education, limited availability and higher price of healthy foods, and fewer leisure and sports facilities.

In low-and middle-income countries:

• Shifts towards higher incomes, better infrastructure, more mechanized agriculture and increased car use.
• Lead to lower energy expenditure and to more spending on food.
