With growing wealth in many developing countries around the world, diet and lifestyle changes are showing dramatic increases in obesity and related diseases like diabetes, heart disease and cancer.
From Central and South America to the Middle East to Asia, weight problems are now among the leading causes of morbidity and mortality. But more than rising standards of living, lack of education seems to contribute to these dismal trends.
In China, India and Brazil, where economic growth has been especially dramatic but has also created vast inequalities in their populations, diet and lifestyle changes have had a particularly profound impact on the risk of obesity, according to one study that investigated the effects of rising incomes on people’s health.
In Mexico, which is considered a middle-income country, prevalence of obesity proved to be the highest among those who were better off financially but had little education. Similar findings were made in Egypt, a low-income country, where obesity has become a fast growing problem, especially among women. Here too, increasing wealth is a predictor – but even more so, lack of schooling.
“For the first time, we have studied the interaction between wealth and education and found they have fundamentally different effects on obesity,” said Dr. Amina Aitsi-Selmi, the lead author of the Egypt study.
Greater exposure of emerging economies to global food markets and rising buying power of consumers lead to these consequences. The best way to prevent this from happening would be to invest in education, especially in women who are in charge of food shopping, cooking, and taking care of the health needs of their families, she said.
“Our study suggests that investing in women’s education protects against this effect by empowering individuals to look after their health,” she said to Science Daily.
As ‘gatekeepers’ in their households, women have the most influence on the nutritional wellbeing of children, which is our best hope for breaking the vicious circle that begins with childhood obesity and subsequent, often chronic, health issues during adulthood.
Scientific evidence leaves no doubt that the environment we live in is largely responsible for the obesity epidemic, Dr. Aitsi-Selmi said. We can only change the environment by changing the behavior of individuals. And that is best accomplished through education.
Obviously, providing even a basic amount of health education in different socio-economic and cultural settings is no easy task in one country, let alone on a global scale. But, as this study and others have shown, increase in literacy and greater opportunities for learning have many benefits and can provide the groundwork for attitude and behavior modifications, including improving eating habits.
It also means that greater affordability of food does not automatically lead to better health outcomes – sometimes to the contrary. Only when people understand how their diet and lifestyle choices affect them, they can make appropriate changes and take control of their wellbeing.
