The prospective impact of food pricing on improving dietary consumption: A systematic review and meta-analysis.

ABSTRACT:

Background

While food pricing is a promising strategy to improve diet, the prospective impact of food pricing on diet has not been systematically quantified.

Objective

To quantify the prospective effect of changes in food prices on dietary consumption.

Design

We systematically searched online databases for interventional or prospective observational studies of price change and diet; we also searched for studies evaluating adiposity as a secondary outcome. Studies were excluded if price data were collected before 1990. Data were extracted independently and in duplicate. Findings were pooled using DerSimonian-Laird's random effects model. Pre-specified sources of heterogeneity were analyzed using meta-regression; and potential for publication bias, by funnel plots, Begg
