A “healthy lifestyle pattern” was defined as never or past smoking; no or moderate drinking of alcohol (one or less drink a day for women, two or less drinks a day for men); BMI of at least 18.5 but lower than 27.5; and weekly aerobic physical activity of at least 150 minutes moderate intensity or 75 minutes vigorous intensity. Individuals who met all four criteria were considered low risk and everyone else was high risk.
The study included 89,571 women and 46,399 men; 16,531 women and 11,731 had a healthy lifestyle pattern (low-risk group) and the remaining 73,040 women and 34,608 men were high risk.
The authors calculated population-attributable risk (PAR), which can be interpreted as the proportion of cases that would not occur if all the individuals adopted the healthy lifestyle pattern of the low-risk group.
The authors suggest about 20 percent to 40 percent of cancer cases and about half of cancer deaths could potentially be prevented through modifications to adopt the healthy lifestyle pattern of the low-risk group.
The authors note that including only white individuals in their PAR estimates may not be generalizable to other ethnic groups but the factors they considered have been established as risk factors in diverse ethnic groups too.
“These findings reinforce the predominate importance of lifestyle factors in determining cancer risk. Therefore, primary prevention should remain a priority for cancer control,” the authors conclude.

As popular as it has become, yoga still doesn’t get the respect it deserves. It is a serious exercise regimen and every bit as good for the heart as other forms of exercise, according to a recent analysis.
And because yoga is a lot less boring than riding a stationary bike, it may even be better than typical exercise when it comes to good heart health.
The authors of the analysis looked at 32 randomized controlled trials of how yoga affected risk factors for heart disease such as high cholesterol or high blood pressure.First, the researchers reviewed trials comparing people who used yoga as a form of exercise to people who did not exercise. Yoga participants had lower body mass index (BMI), blood pressure (both systolic and diastolic) and cholesterol (both LDL and total) and had higher HDL (good) cholesterol.
They also had lower triglycerides and heart rate, and were more likely to lose weight during the trial. In fact, the only outcomes recorded where yoga did not lead to measurable improvements were fasting blood glucose and glycosylated hemoglobin.
In trials comparing yoga’s effects to the impact of other types of aerobic exercise, such as cycling or brisk walking, the results were even simpler: there was no significant difference between yoga and other exercise.
The researchers caution that many of the trials were of rather short duration and had small numbers of participants, so it’s possible that the results of larger or longer trials might be different.
Yoga may even have an edge over traditional forms of exercise. It tends to be more acceptable to patients with physical disabilities, including people with joint pain, heart problems and the elderly. It also requires no special equipment and can be performed.
The study is published in the European Journal of Preventive Cardiology.
