Lessons From a Pilot Community-Driven Approach for Obesity Prevention.

Introduction: The Wisconsin Obesity Prevention Initiative has piloted a novel approach for community action for obesity prevention that incorporates both coalition and community organizing efforts in 2 counties. This article describes lessons learned to date from this experience.

Methods: A description of the progress made in these communities and the support provided by Initiative staff and other partners are drawn from process evaluation of the pilot from November 2014 through December 2015, as well as the reflections of community partners.

Community-Led Collaborative Action to Prevent Obesity.

At the population level, turning the tide on obesity requires not only health education and promotion programs, but also systemic changes in our society. However, few of these changes can be implemented by single agencies or organizations acting in isolation. Broader community-driven efforts are needed to advance and maintain systematic changes across multiple settings.

Improving wastewater-based epidemiology to estimate cannabis use: focus on the initial aspects of the analytical procedure.

Wastewater-based epidemiology is a promising and complementary tool for estimating drug use by the general population, based on the quantitative analysis of specific human metabolites of illicit drugs in urban wastewater. Cannabis is the most commonly used illicit drug and of high interest for epidemiologists. However, the inclusion of its main human urinary metabolite 11-nor-9-carboxy-Δ-tetrahydrocannabinol (THC-COOH) in wastewater-based epidemiology has presented several challenges and concentrations seem to depend heavily on environmental factors, sample preparation and analyses, commonly resulting in an underestimation.
