Despite the importance of updating countries’ nutrition
policies to reflect the nutrition transition [25], no
study has reviewed the presence of such policies. Evidence
is also lacking on the potential effects of nutrition
policies to address trends in nutrition status including
stunting, underweight, wasting, and overweight/obesity.
Nutrition policy may need accompanying country-level
nutrition governance in order to implement nutrition related
interventions and achieve the desired output. In
this aspect too, evidence is lacking. We therefore conducted
this review to examine whether low and middleincome
countries have nutrition policies to address the
burdens of undernutrition and overweight/obesity, and
the association of such policies and nutrition governance
on magnitudes of undernutrition and overweight.
