Style de vie sain: risque de mortalité réduit de 66%

The combined effects of healthy lifestyle behaviors on all cause mortality: A systematic review and meta-analysis

Preventive Medicine
Volume 55, Issue 3, September 2012, Pages 163170

Martin Loef, Harald Walach
Lifestyle factors are related to mortality. Although much is known about the impact of single factors, the current evidence about the combined effects of lifestyle behaviors on mortality has not yet been systematically compiled.
We searched Medline, Embase, Global Health, and Somed up to February 2012. Prospective studies were selected if they reported the combined effects of at least three of five lifestyle factors (obesity, alcohol consumption, smoking, diet, and physical activity). The mean effect sizes that certain numbers of combined lifestyle factors have on mortality were compared to the group with the least number of healthy lifestyle factors by meta-analysis. Sensitivity analyses were conducted to explore the robustness of the results.
21 studies (18 cohorts) met the inclusion criteria of which 15 were included in the meta-analysis that comprised 531,804 people with a mean follow-up of 13.24 years. The relative risks decreased proportionate to a higher number of healthy lifestyle factors for all cause mortality. A combination of at least four healthy lifestyle factors is associated with a reduction of the all cause mortality risk by 66% (95% confidence interval 58%73%).
Adherence to a healthy lifestyle is associated with a lower risk of mortality.
...In conclusion, we found that a combination of lifestyle-related behaviors, such as not smoking, drinking alcohol in moderation, eating healthily, regular exercise, and maintaining an optimal weight, is associated with a reduction in mortality by 66%. Our meta-analysis provides strong support for the further promotion of a healthy lifestyle by governments, foundations, and the World Health Organization. If people accepted the responsibility for their own health, the worldwide costs and burden of disease could be greatly reduced.

Tobacco withdrawal symptoms and urges to smoke in pregnant versus non-pregnant smokers


We compared tobacco withdrawal in pregnant and non-pregnant smokers abstaining from smoking for 24 hrs. Female smokers completed an internet-based questionnaire, including the Minnesota Nicotine Withdrawal Scale-Revised (MNWS). They also rated additional withdrawal items and strength of urge to smoke. Consenting women were randomized to either: (i) abstain from smoking for 24 hrs or (ii) smoke as usual. After 24 hrs they rated their withdrawal again. We included a smoking as usual' group as we wished to establish that smoking abstinence increased withdrawal symptoms. Two-hundred and seventy-five women completed both the initial and the 24 hr questionnaire and reported abstaining (n = 115, 17% pregnant) or smoking (n = 160, 21% pregnant) as requested. Exclusively among abstinent smokers, we compared symptoms for the pregnant and non-pregnant groups. After 24 hrs pregnant women had significantly lower scores than non-pregnant women for the mean MNWS (p = 0.004) and for three individual MNWS symptoms (angry, p = 0.010; anxious, p = 0.048; impatient, p = 0.011), with adjustments for baseline cigarette consumption and baseline withdrawal scores. Overall, on the first day of smoking abstinence, pregnant women are likely to report less severe tobacco withdrawal than non-pregnant women.
