Children in federally assisted housing have lower blood lead levels than expected
According to a new study in the American Journal of Public Health, U.S. children living in federally assisted housing have lower blood lead levels than comparable children who did not receive housing assistance.
Researchers examined data for National Health and Nutrition Examination Survey respondents from 2005-2012 that were linked to 1999-2014 records from the Department of Housing and Urban Development. For households that fell within less than 2 times the national poverty threshold, they compared blood lead levels of children ages 1-5 living in assisted-housing with those of children who did not receive assisted-housing.
Results showed that in unadjusted analyses, blood lead levels for children living in federally assisted housing were not significantly different than children who did not receive housing assistance. However, after adjusting for potential confounding factors – including demographic, socioeconomic and family characteristics – children living in federally assisted housing had lower blood lead levels than their non-assisted housing counterparts.
“In a nationally representative sample of US children 1 to 5 years old in 2005 to 2012, children receiving federal housing assistance had lower blood lead levels than expected given their demographic, socioeconomic and family characteristics," the authors explain. "This study adds to the literature describing how factors related to housing conditions and stability are associated with health among U.S. children and can help inform future research.”

States with operational medical marijuana laws show reductions in opioid use
According to a new study in the American Journal of Public Health, states with operational medical marijuana laws showed a reduction in opioid positivity among 21- to 40-year-old fatally injured drivers, indicating a potential reduction in opioid use and overdose.
Researchers analyzed 1999-2013 Fatality Analysis Reporting System data from 18 U.S. states that tested for alcohol and other drugs in at least 80 percent of drivers who died within one hour of crashing. They compared opioid positivity among drivers crashing in states with an operational medical marijuana law – such as allowances for home cultivation or active dispensaries – versus drivers crashing in states before those laws went into effect.
Results showed that among 21- to 40-year-old deceased drivers, crashing in states with an operational medical marijuana law was associated with lower odds of testing positive for opioids than crashing in these states before the laws were operational. Results also showed an overall reduction in opioid positivity for most states after implementation of an operational medical marijuana law.
“In theory, we would expect the adverse consequences of opioid use to decrease over time in states where medical marijuana use is legal, as individuals substitute marijuana for opioids in the treatment of severe or chronic pain,” the authors explain. “As states with these laws move toward legalizing marijuana more broadly for recreational purposes, future studies are needed to assess the impact these laws may have on opioid use.”

Majority of e-cigarette advertisements imply products help consumers quit smoking
The majority of leading e-cigarette brands use cessation themes in their advertisements that imply the products help consumers quit smoking, according to new research in the American Journal of Public Health.
Researchers analyzed the content of advertising by e-cigarette brands on company-sponsored social media channels and blogs and user testimonials appearing within brand-sponsored websites. They then assessed claims of cessation efficacy as explicit – unambiguously stating that e-cigarettes help consumers quit smoking – or implicit – using euphemisms such as “it works.”
Results showed that among 23 leading e-cigarette brands, 22 used cessation-themed advertisements. Overall, 23 percent of the total advertisements from those brands contained cessation claims, of which 18 percent were explicit and 82 were implicit.
“Given the lack of scientific evidence regarding cessation efficacy, there is no rational basis for e-cigarette brands to assert cessation efficacy when advertising their products,” the authors explain. “It is conceivable that future technical advances and chemical modifications may achieve nicotine delivery similar to combustible cigarettes. If and when a specific e-cigarette brand can present data supporting its efficacy as a cessation device, the product should be subject to FDA regulation as a drug, device, or combination product requiring prior approval.”
