Women who believe smoking helps them manage their weight are less likely to try quitting in response to anti-smoking policies than other female smokers in the U.S. The study, published online in the journal Tobacco Control, is the first to find that smokers who are concerned about their weight are less swayed by anti-smoking policies – such as bumps in cigarette prices, smoke-free laws or anti-tobacco messaging — than other smokers are.
The study findings suggest that women may need support that addresses concerns about weight gain, said Shang, who is a senior research specialist in UIC’s Institute for Health Research and Policy. “Policymakers should take weight concerns into account to enhance the effectiveness of existing policies that promote quitting smoking,” she said. Additional education on smoking and weight could be useful for programs that target women, Shang said.
The researchers looked at survey data from about 10,000 smokers in the U.S., Canada, the U.K. and Australia as part of the International Tobacco Control Policy Evaluation Project. The ITC Project conducts longitudinal surveys of smokers and tobacco users across 22 countries.
For female smokers who did not believe that smoking helps control weight, a 10 percent increase in cigarettes price was associated with a 6 percent rise in attempts to quit, while women who thought smoking does help control weight did not significantly increase their attempts to quit in response to a price increase. Additionally, while a 10 percent increase in exposure to anti-smoking messaging was associated with a 12 percent increase in quit attempts among those who did not hold the weight-control belief, no increase in quit attempts was reported by smokers who did so believe. Shang noted that those who smoke more tobacco are more likely to be overweight than smokers who smoke less, “so the idea that smoking helps control weight is really unfounded.” “Plus,” she said, “the health benefits that come from quitting allow for more healthy methods of weight control, such as exercise.”
