Nutrition Environment Measures Survey
The Nutrition Environment Measures Survey (NEMS) is a family of structured observation instruments for assessing the consumer nutrition environment — the in-store and in-restaurant conditions that shape what people can actually buy and eat. Developed by Karen Glanz, James Sallis, Brian Saelens and Lawrence Frank and published in 2007, NEMS-S audits retail food stores and NEMS-R audits restaurants, each scoring the availability, price and quality of healthier options relative to standard ones. Trained raters apply a fixed protocol so that two independent observers reach the same verdict, and the resulting scores let researchers compare neighbourhoods, link environments to diet and obesity, and evaluate interventions. NEMS is widely regarded as a foundational, validated tool for measuring the food environment and has been adapted across diverse settings since its release.

Madai yaliyotunzwa
Madai yamehifadhiwa katika daftari la ushahidi, kila moja ikiwa na tathmini yake.
Mwonekano huu haubuni tathmini ya dai wakati daftari haina yoyote.
Mbinu zinazohusiana
Zilizotengenezwa kutoka kwa grafu ya mbinu na kuonyeshwa kama uhusiano uliopendekezwa na mashine — hakuna dai la ushahidi linalodokezwa.
