Secondhand smoke harms smokers too

Smokers who inhale their own secondhand smoke add significantly to the health risks linked to cigarette smoking, say researchers.
Until now it has been believed that such risks would be negligible in comparison to those incurred due to actual smoking.
Maria Teresa Piccardo worked with a team of researchers from the National cancer Research Institute, Genoa, Italy, to study the exposure of newsagents in the city to harmful cigarette smoke.

The experts found for someone who smokes 14 cigarettes a day, their own second hand smoke resulted in exposure the equivalent of smoking an extra 2.6 cigarettes.
Piccardo said: “Newsagents were chosen because they work alone in small newsstands, meaning that any tobacco smoke in the air they breathe is strictly
correlated to the number of cigarettes smoked by that newsagent. We studied
the contribution environmental tobacco smoke made to carcinogen exposure in 15
active smokers.”

“Both active and passive smoking contributions should always be considered in studies about health of active smokers.”

Alcohol increases likelihood of intimate partner violence
A new study has shown that alcohol increases the likelihood of violence among couples- both to and by the female partner.

According to researchers from University of Texas School of Public Health in Dallas, while the chances of severe male-on-female violence tripled, severe female-on-male violence also more than doubled when the woman drank.

Study co-author Dr Raul Caetano said that severe partner violence was more than twice as likely when the woman drank alcohol.Most studies of alcohol use and partner violence have looked only at male-on-female violence and many of the surveys rely on people who ended up in hospitals or the legal system, he said.
Women who are in a physically abusive relationship might be drinking as a form of self-medication, said Rita Smith, executive director of the National Coalition Against Domestic Violence in Denver.

“It could be as much that factor as that they have an alcohol abuse problem. We don’t know that,” she added.
“The one thing that is important is that this is a random sample of couples in the US. When you go into general population, you pick up much more violence that is less severe and you see female involvement more clearly,” added Caetano.

Overweight elderly live longer: Study
Being fat may not be all that bad — but only if you’re 70, concludes a new study.
The study found that adults aged over 70 years, classified as overweight, were less likely to die over a 10-year period than adults who were in the ‘normal’ weight range. Boffins looked at data taken over a decade among 9,200 Australians aged between 70 and 75, who were assessed for their health and lifestyle as part of a study into healthy aging.

Obesity and overweight are most commonly defined according to body mass index (BMI), which is calculated by dividing bodyweight (in kg) by the square of height (in metres). The WHO defines four principal categories: underweight, normal weight, overweight, and obese. The thresholds for these categories were primarily based on evidence from studies of morbidity and mortality risk in younger and middle-aged adults, but it remains unclear whether the overweight and obese cut-points are overly restrictive measures for predicting mortality in older people.
