Exposure to physical assault is associated with premature mortality in Russian men

Our study, published recently in the IJE, looks at the relationship between experience of violence, in the form of physical assault in the previous 12 months, and premature mortality in a sample of working-age Russian men living in Izhevsk in the Southern Urals.

We did this study because, although violence is considered important at a policy and political level, empirical public health research on the subject is patchy. There has been quite a lot of research on the relationship between violence exposure and later mental health problems, particularly post-traumatic stress disorder, and more generally the impact of violence on coping and psychological characteristics, particularly in children. Recently, there has been considerable work on the descriptive epidemiology of violence against women, both from a general population perspective and in studies focusing on women with serious mental illness.

In contrast, we found that population-based research on the physical health effects of exposure to violence was limited, and we decided to focus on possible associations between assault and mortality in our study.

Metabolic Phenotyping in Epidemiology

g-mak-talisker-jan-2016-bristol-wwwMika Ala-Korpela and George Davey Smith

Metabolic phenotyping, nowadays most often termed metabolomics, is becoming increasingly applied in epidemiology. Recent technological developments, driven by mass spectrometry and nuclear magnetic resonance spectroscopy, have recently resulted in increasing numbers of quantitative molecular applications at an epidemiological scale. The results suggest that these kinds of new technologies are inevitably becoming common in research projects aiming for molecular understanding of metabolic health and diseases. It is also evident from the epidemiological applications that absolute quantification of identified molecular entities is the very key for biomedical applications, not to mention potential clinical translation of metabolomics methodologies and findings.

Evolution or revolution? The health of New Yorkers under Mayor Bloomberg

Peter Muenning, Daniel Vail and Ryan K. Masters

hss_cohort9-ryan-mastersdaniel121757476_title0hWhen Michael Bloomberg was elected Mayor of New York City (NYC), he set forth an ambitious agenda to efficiently sync municipal agencies. Improving New Yorkers’ health was part of his motivation. For example, expanding parks and bike lanes would not only improve people’s quality of life and expand transportation options, their presence would also encourage healthy behaviours. So, why not create cross-agency agendas that allow parks with bike lanes to be created on city streets? Innovative thinkers were hired and were given an unusual amount of political capital and logistical support to implement their plans.

Sadly, very little was done to actually evaluate the programs that were implemented. When the Bloomberg administration promoted the idea that life expectancy had greatly increased as a result of its coordinated policymaking, some people scratched their heads. Sam Preston and Irma Elo argued that improvements in life expectancy in NYC could be explained by a large inflow of healthy foreign migrants. They made this argument by eloquently showing the influence that immigrants had on the city’s life expectancy.

Marking World AIDS Day 2016

 

World AIDS Day is held on 1 December every year and provides an opportunity for people across the globe to show solidarity with the millions of people living with HIV. This year’s campaign theme is ‘HIV Stigma: Not Retro, Just Wrong’ #HIVNotRetro and you can find out more about how to get involved at  https://www.worldaidsday.org/.

New evidence that maternal micronutrient status modifies the effect of neonatal vitamin A supplementation

headshotEmily Rose Smith


Although the World Health Organization (WHO) recommends vitamin A supplementation for infants and preschool children aged 6 to 59 months to reduce morbidity and mortality, the debate about whether or not to supplement newborns has been controversial.  (Note that an exchange in IJE 44:1 in 2015 also demonstrated some controversy about whether or not to continue supplementation for preschool-aged children). In an attempt to inform global policy, three large clinical trials were conducted in Tanzania, Ghana, and India. However, these trials found conflicting results. The trial conducted in India—consistent with previous trials in the region—found that supplementation reduced the risk of infant death, while the other two trials in Ghana and Tanzania found no effect of supplementation.

Inconsistency between the trials might indicate that some, but not all, children benefit from neonatal vitamin A supplementation (NVAS). Our study, published in the IJE, examines data from the Neovita trial in Tanzania, the largest NVAS study ever conducted in sub-Saharan Africa. We looked to see if there were any subgroups of infants in this trial who benefited from supplementation.

Last but not least – the 2016 IJE conference

The IJE conference took place in Bristol on 7 October  2016, a one-day, one-off event.

Rodolfo Saracci, as ever bow-tied and in good spirits, did the honours throughout the day. It was under his IEA presidency that Shah Ebrahim and George Davey Smith were hired as IJE editors, and Rodolfo praised their editorial work by likening it to conducting research (“exciting, adventurous, challenging”), and acknowledging that brave decisions have exposed them to the future judgement of historians.

A historical perspective was also taken by Tom Koch, who recalled the very origins of the IJE, of epidemiology itself, and of the transition to modern epidemiology, and by Alex Mold, who told us about the historical relationship between the public and public health by drawing on three key epidemiological narratives (John Snow and the pump’s handle, Richard Doll and the British Doctors’ study, Jerry Morris and London’s bus drivers and conductors).

You should totally watch this entire day of the IJE conference

Today marks the end of an era. The International Journal of Epidemiology used to be a typical hotchpotch of isolated papers on worthy subjects. Occasionally, some were interesting, or related to your field. Under Shah Ebrahim and George Davey Smith it became like nothing else: an epidemiology journal you’d happily subscribe to with your own money, and read in the bath.

Genome-wide association study gives rise to a new breed of disease network

A puzzling similarity
Researchers have long noted puzzling similarities between Hodgkin lymphoma and multiple sclerosis. Although the first is a cancer and the second is an autoimmune disease, risk for both diseases appears to increase due to the Epstein–Barr virus and a lack of sunlight. In fact having a family member with multiple sclerosis may place you at increased risk for Hodgkin lymphoma and vice versa. Now, a recent study, on which I am a co-author, has identified genetic similarities. Continue reading “Genome-wide association study gives rise to a new breed of disease network”

World Cancer Day 2016

WCD with logoWorld Cancer Day is a global event which takes place annually on 4 February to educate and raise awareness about the disease with the aim of saving millions of preventable deaths each year. This year’s theme ‘We can. I can’ explores how everyone can do their part to reduce the global burden of cancer.

To mark World Cancer Day, the International Journal of Epidemiology has published a free article collection (available until 4 May 2016) showcasing the latest epidemiological research into a variety of risk factors for cancer: Continue reading “World Cancer Day 2016”
