In (Caballero, 2007). Developing countries are now

In the last few decades of the twentieth century, overweight and obesity
have become a major threat for the higher income countries. It has already reached the
epidemic level in developed countries of America, Europe with prevalence rate
of 63 and 59 per 1000 respectively (WHO estimates 2016). Obesity has been found to be a strong predictor
of several well-established risk factors for increased morbidity and mortality.
They are directly linked
with the rise in non-communicable diseases like diabetes, hypertension etc. The global increase in overweight and obesity
at the young age is directly linked with the risk of cardiovascular and other
chronic diseases. Worldwide, at least 2.8 million people die each year as a result of being overweight or obese,
and an estimated 35.8 million (2.3%) of global DALYs are caused by overweight
or obesity (WHO). Also there is a concern that the
rise in global obesity will slow down or even reverse the significant mortality
reductions experienced by the high income countries in the past few decades
(Swinburn et al. 2011).  Reversing the obesity epidemic
should be an urgent priority (Mokdad et al., 2003).  Earlier, higher proportion of population
suffering from problems of over-weight and obesity resided in higher income and
industrialized countries (Caballero, 2007). Developing countries are now going
under various transitions like demographic, epidemiological, economic, as well
as nutritional transition. Due to this, for countries like India, the issue is
more serious. Earlier developing countries had high prevalence of under-nutrition
but now there is a double burden of under-nutrition as well as over-nutrition. In developing countries, malnutrition is a
medical as well as a social disorder (Sidhu & Kaushal, 2005). This double burden of
over-nutrition and under-nutrition is now a public health challenge in
developing countries. Under-nutrition is still a significant cause of deaths of
children in less developed and developing countries.
Although eradicating hunger was a part of Millennium Development Goal,
undernutrition still continues to be prevalent in low-income and middle-income
countries throughout the world. Almost all the health and nutrition policies in the developing countries
is emphasising on undernutrition but at the same time, rising prevalence of
over-nutrition is now a serious health threat. Childhood obesity was considered
as an issue in the economically rich countries, but now this problem has
started appearing in the less developed countries also. Childhood obesity is
now a recent epidemic with high magnitude in India (Tanu Midha et al., 2012).  Due
to rise in overweight and obesity in the recent decades, it is now important
for the countries to focus on regular monitoring of prevalence of it in the
population.
