Results of the systematic review: the effect of agricultural price policies on nutritional status and health

Author (year)	Country	Policy	Commodities	Data sources	Methods	Outcome	Findings
Panel A: undernutrition outcome
Tarozzi11	India (Andhra Pradesh)	Indian food subsidy programme	Rice, wheat, edible oils, sugar and cooking oil	National Family Health Survey to provide data on child anthropometry in affected area	Ex post analysis of the effect of a higher price regime for rice covered by the subsidy programme. Multiple regression used to assess differences in child undernutrition in relation to time in high price regime	Weight-for-age	No evidence for an association between length of time spent in the higher price regime and child nutritional status as assessed by weight-for-age
Panel B: overnutrition and nutrition-related chronic disease outcomes
Veerman et al12	The Netherlands	European Union withdrawal support policy	Fruit and vegetables	Estimate of fruit and vegetable (tonnes) withdrawn Dietary intake data from national nutrition survey Estimates of national disease frequencies Diet-disease relationship relative risks	Ex ante models of the effect of a change in dietary intake of fruit and vegetables on disease risks (potential impact fractions) and integrate the changes in disease-specific data into national life tables	Disability-adjusted life years (DALYs) and life expectancy	Removal of fruit and vegetable withdrawal policy would slightly increase fruit and vegetable consumption, reduce the incidence of cardiovascular disease and cancer, reduce the DALYs lost per year and modestly increase life expectancy
Asfaw15	Egypt	Egyptian food subsidy programme	Bread, wheat flour, sugar and cooking oil	Integrated Household Survey to provide estimate of household food expenditure (and hence food consumption) and body mass index of mothers	Ex post multiple regression and econometric estimation of effect of food subsidy policy	Body mass index of mothers	Increases in the price of bread and sugar were associated with significant reduction in body mass index of mothers
Okrent and Alston13	USA	Farm subsidies on grain commodities	Eight food groups consumed at home, a composite variable for food consumed away from home, and alcoholic beverages	National data on use of farm commodities and retail products Dietary intake data from national nutrition survey Estimated change in weight from change in calorie consumption	Ex ante equilibrium displacement models of the effect of removal of farm subsidy policy	Adult weight	Removal of existing farm subsidies on grain commodities would result in a modest reduction in weight
