Disordered Eating May Affect up to 15 Percent of Women

Several maladaptive eating behaviors, beyond anorexia, can affect women. Indeed, some 10 to 15 percent of women have maladaptive eating behaviours and attitudes according to new study from the Université de Montréal and the Douglas Mental Health University Institute published in the International Journal of Eating Disorders.

“Our results are disquieting,” says Lise Gauvin, a professor at the Université de Montréal Department of Social and Preventive Medicine. “Women are exposed to many contradictory messages. They are encouraged to lose weight yet also encouraged to eat for the simple pleasure of it.”

Some 1,501 women took part in the phone survey on eating disorders and disordered eating. Not one participant was classified as anorexic. The average age of these urban-dwelling participants was 31, the majority of respondents were non-smokers and university graduates.

Dr. Gauvin says the study sheds new light on binge eating and bulimia, which are characterized in part by excessive eating accompanied by feelings of having lost control. “About 13.7 percent of women interviewed for this study reported binge eating one to five days or one to seven times per month,” she says, noting 2.5 percent of women reported forcing themselves to vomit, use laxatives, or use diuretics to maintain their weight or shape.

The investigation also established a link between problematic eating behaviours and self-rated health. In other words, deviant eating behaviours are more likely to occur in women who perceived themselves to be in poor health.

Another finding of the study was that 28 percent of women complete intense exercise twice a month with the sole objective of losing weight or influencing. “We practice a sport for the pleasure it provides, to feel good, but when the activity is done to gain control over one's weight and figure, it is indicative of someone who could be excessively concerned about their weight,” says Dr. Gauvin. “Our data suggests that a proportion of the female population displays maladaptive eating patterns.”

This study was supported by the Canadian Institutes for Health Research.

Overtime is bad for the heart

Working overtime puts people at increased risk of coronary heart disease, according to a new study published in the European Heart Journal. CHD occurs when plaque builds up in and narrows the arteries through which blood reaches the heart, which can lead to a heart attack. Specifically, working three to four hours extra (amounting to an 11- or 12-hour work day) was associated with a 1.56-fold increased risk of CHD.

Previous studies have also shown that overtime work is linked to hypertension, sleep problems and depression.

The European researchers followed 6,014 British civil servants aged 39 to 61 for 11 years. Just less than half worked at least one hour of overtime a day, or up to four hours. Those who worked overtime were more often young, male, married or living with a partner, and in more prestigious occupations. The risk of CHD increased in tandem with the number of extra hours worked.

Overtime workers slept less, and reported higher rates of “psychological distress,” according to the study. They often exhibited “Type A behaviour,” which the researchers define as “a chronic, incessant struggle to achieve more and more in less and less time, and is also believed to be characterized by aggressiveness and irritability,” which is also a risk factor for CHD. The researchers also speculate that overtime workers ignore illness, which may aggravate health problems over the long-term.

Perhaps surprisingly, these participants did not exhibit other behaviours that would compromise their heart health: Overtime workers did not drink excessively, smoke or have diabetes. In fact, they actually had better habits—consuming more fruits and vegetables and exercising more often—than those workers who never clocked overtime hours.

In an accompanying editorial entitled “Overtime is bad for the heart,” Gordon McInnes of the University of Glasgow concludes with a quotation from English philosopher Bertrand Russell: “If I were a medical man, I should prescribe a holiday to any patient who considers work important.”
