Comparative Study
Comparisons of Estimates From the Behavioral Risk Factor Surveillance System and Other National Health Surveys, 2011-2016.
The Behavioral Risk Factor Surveillance System (BRFSS) is composed of telephone surveys that collect state data from non-institutionalized U.S. adults regarding health-related risk behaviors and chronic health conditions. A new design was implemented in 2011 to include participants on cellular telephones. It is important to validate estimates since 2011. ⋯ Comparing BRFSS time trends with those of 2 national benchmark surveys in 10 key and widely used variables suggests that the trends of prevalences (or means) from BRFSS, NHANES, and NHIS are mostly similar. For many variables, despite statistically significant differences in the prevalences (or means) between surveys, absolute differences in most cases were small and not meaningful from a public health surveillance perspective.

Needle and syringe programs and opioid agonist therapy are essential for harm reduction among people who inject drugs. Few studies assess their combined potential in preventing hepatitis C virus infection. No studies have assessed whether they perform similarly among individuals at risk of primary and recurrent infection. This study aimed to estimate the rates of hepatitis C virus acquisition according to harm reduction coverage among hepatitis C virus-naive and previously infected people who inject drugs in Montreal, Canada. ⋯ High-dose opioid agonist therapy seems particularly important to reduce drug-related harms among hepatitis C virus-naive and previously infected people who inject drugs in Montreal.

The geographic overlap of violence and poor health is a major public health concern. To understand whether and how place-based interventions targeting micro-geographic places can reduce this undesirable co-occurrence, the study addresses 2 important questions. First, to what extent are deteriorated health conditions associated with living at violent crime hot spots? Second, through what mechanisms can focused place-based interventions break the association between living with violence and deteriorated health? ⋯ Indicated or selective strategies are urgently needed to target micro-geographic locations with known increased risks, supplementing universal strategies applied to a broader community.
