BMJ Open’s first impact factor has been announced: 1.583. We are delighted to have this further evidence that BMJ Open is considered a journal of credible, valued research. Does a journal’s impact factor matter? In short – yes. When we surveyed our authors earlier this year, we asked what improvements we could make to […]

Moderate drinking during pregnancy does not seem to harm baby’s neurodevelopment
Moderate drinking during pregnancy – 3 to 7 glasses of alcohol a week – does not seem to harm fetal neurodevelopment, as indicated by the child’s ability to balance, suggests a large study published in BMJ Open. But social advantage may be a factor, as more affluent and better educated mums-to-be tend to drink more […]
Average UK salt content of packaged bread has fallen 20 per cent in a decade
The average salt content of packaged bread sold in the UK has fallen by 20 per cent over the past decade. But salt levels still vary widely, indicating that further targets are required, finds research published in BMJ Open. Bread is the biggest contributor of dietary salt in the UK, providing almost a fifth of […]
Every 10 tobacco ad sightings boost teens’ risk of starting to smoke by almost 40 per cent
Tobacco ads really do persuade teens to take up smoking, with every 10 sightings boosting the risk by almost 40 per cent, reveals research published in BMJ Open. The researchers base their findings on over 1300 ten to 15 year old non-smokers whose exposure to tobacco advertising and subsequent behaviour were monitored over a period […]
The incidence of eating disorders is increasing in the UK
More people are being diagnosed with eating disorders every year and the most common type is not either of the two most well known—bulimia or anorexia—but eating disorders not otherwise specified (eating disorders that don’t quite reach the threshold to be defined as anorexia or bulimia), shows a study published online in BMJ Open. Few […]
Bed sharing with parents increases the risk of cot death fivefold even if the parents are non-smokers
Bed sharing with parents is linked to a fivefold increased risk of sudden infant death syndrome (SIDS), even when the parents are non-smokers and the mother has not been drinking alcohol and does not use illegal drugs, according to a large analysis published online in BMJ Open. While the rate of SIDS has fallen sharply […]
Obesity in early 20s curbs chances of reaching middle age
Young men who are obese in their early 20s are significantly more likely to develop serious ill health by the time they reach middle age, or not even make it that far, suggests research published in BMJ Open. It’s well known that obesity in adulthood poses a risk for diabetes and cardiovascular disease, but it’s […]
Painkillers taken before marathons linked to potentially serious side effects
Attempts to ward off pain in marathons and other endurance sports by taking over the counter painkillers may be ill advised, because these drugs may cause serious side effects in these circumstances, suggests research published in BMJ Open. Many competitors try to prevent pain interfering with their performance by taking painkillers that are readily available […]
Baldness linked to increased risk of coronary heart disease
Male pattern baldness is linked to an increased risk of coronary heart disease, but only if it’s on the top/crown of the head, rather than at the front, finds an analysis of published evidence in BMJ Open. A receding hairline is not linked to an increased risk, the analysis indicates. The researchers trawled the […]
Myth that UK supply of innovative new pharma drugs is drying up
The widely held belief that the UK supply of innovative new medicines has conspicuously dwindled in recent decades, is not borne out by the evidence, reveals research published in BMJ Open. In fact, the reverse may be true, the figures suggest. The prevailing view is that pharmaceutical industry innovation has been in decline, with […]
