What’s the correlation between the occasional or regular use of cannabis by adolescents and its progression to nicotine dependence, harmful alcohol use and use of other illicit drugs in young adulthood? What impact could the wider availability of cannabis have on this advance? Complex questions that Michelle Taylor (Senior Research Associate in Epidemiology, School of Social and Community Medicine, Bristol. UK) answers in this podcast. The interview, inspired by a study published in the Journal of Epidemiology and Community Health, is conducted by the editor of the journal, Jim Dunn. Dr Taylor also talks about the differences in gender and possible policy implications of her group’s findings. Read the details of the study “Patterns of cannabis-use during adolescence and their association with harmful substance use behaviour: Findings from a UK birth cohort” in the JECH website: http://jech.bmj.com/content/early/2017/05/17/jech-2016-208503.

How is the use of cannabis in adolescents likely to progress to harder drugs?

Prenatal sex selection and female infant mortality are more common in India after first and second born daughters. Corry Gellatly, a research scientist at the Newcastle University, explains the details of his study, in a podcast conducted by the Editor in Chief of the Journal of Epidemiology and Community Health, James Dunn. The article is accessible here: http://jech.bmj.com/content/71/3/269.

Job insecurity has been identified as a risk factor for adverse health outcomes. Perceptions of job insecurity steeply increased during Europe's recent economic downturn, which commenced in 2008. A study just published in JECH assessed whether job insecurity was associated with incident asthma in Germany during this period. Jim Dunn talks discusses the findings with lead author Adrian Loerbroks, Institute of Occupational and Social Medicine, Centre for Health and Society, Faculty of Medicine, University of Düsseldorf.

The link between emotional stress and an enhanced risk of cardiovascular death is well established. In particular, sports events such as soccer matches are capable of provoking strong emotions, which might cause a failure of the cardiovascular system, and thus a peak of death numbers in the population. Now a study published in JECH has examined the number of deaths in Germany on match days of the national soccer team during a long-term period including several tournaments. Editor Jim Dunn talks to lead author Daniel Medenwald, Institute of Medical Epidemiology, Martin-Luther-University of Halle-Wittenberg.

Childhood obesity is now a global epidemic and the incidence continues to increase. Dietary interventions and nutritional education are possible options, however, restrictive diets can result in negative outcomes, and therefore it may be more apt to encourage children to consume more fruit and vegetables.Along with colleagues from the University of Manchester, Michael Bourke has conducted a review on this question, published in JECH, and he talks to editor Jim Dunn about what they found.Read the paper here: http://goo.gl/TWtA4O

There has been long-standing interest in the idea of polypill (a pill containing a statin and an anti-hypertensive agent) being used by healthy people, as a tool to prevent heart disease (and possibly other diseases). In a recent paper in JECH, Michael Holmes and Neeraj Bhala suggest that polypill may be used similarly as vaccines have been used for communicable diseases. This podcast presents a discussion on the polypill concept and whether the current evidence is good enough to advocate its large scale use.See also:The physiological paradox: reframing the polypill as a vaccine for cardiovascular disease http://bit.ly/1kHBD6fPopulations and polypills: if yes, then how? http://bit.ly/1g4KVTSPolypill is not a ‘vaccine-like’ solution for primary cardiovascular disease prevention in all parts of the world http://bit.ly/1g4KM2K
