Using cellphones and accelerometers to track food intake and energy expenditure in rural areas of developing countries Measuring whether people in developing countries own enough nutritious food to eat is vital work. It warns policymakers when people are running out of food,and is critical to staving off malnutrition.
It’s also time consuming and expensive. Teams fan out, often to rural, or isolated areas,to carry out in-person interviews at homes, a months-long task.
But there might be an easier, or less expensive way to carry out it,said Patrick Webb, Alexander McFarlane Professor of Nutrition at the Friedman School, and who focuses on food insecurity and programs that try to alleviate it.
