Many people who smoke say they are afraid to stop smoking for fear of gaining weight. However, new research suggests that reductions in smoking rates had less than a 1% effect on increased rates of obesity nationwide. Further, a forthcoming study shows that among weight-concerned smokers trying to quit, nicotine has only a small and temporary effect on weight maintenance.
What does contribute to weight gain? A social network analysis of over 12,000 people between 1971 and 2003 showed that friends and family are key. Specifically,
- Individuals were 57% more likely to become obese if a friend became obese
- 40% more likely if a sibling became obese.
- 37% more likely if a spouse became obese.
- Further, same sex friends and family members had more influence on weight gain than opposite sex friends and family members.
High rates of smoking and obesity are significant health issues facing the Commonwealth. Public policymakers can use research-based information to develop strategies for addressing these issues. Based on recent research, possible approaches might include smoking cessation programs that integrate nutrition and healthful eating curricula, family-based physical activity programs, and ad campaigns that dispel myths about the link between smoking cessation and obesity.
