Impact of nutrition environmental interventions on point-of-purchase behavior in adults: a review

摘要: Abstract Background. Nutrition interventions targeted to individuals are unlikely significantly shift US dietary patterns as a whole. Environmental and policy more promising for shifting these patterns. We review that influenced the environment through food availability, access, pricing, or information at point-of-purchase in worksites, universities, grocery stores, restaurants. Methods. Thirty-eight nutrition environmental intervention studies adult populations, published between 1970 June 2003, were reviewed evaluated on quality of design, methods, description (e.g., sample size, randomization). No met inclusion criteria found. Results. Many not thoroughly lacked important evaluation information. Direct comparison across settings was possible, but available data suggest worksite university have most potential success. Interventions stores appear be least effective. The dual concerns health taste foods promoted rarely considered. Sustainability change never addressed. Conclusions. “limited access” sites (i.e., where few other choices available) had greatest effect choices. Research is needed using consistent better assessment tools, longer durations; targeting diverse populations; examining sustainability. Future should influence access policies, macroenvironments.
