Non-smokers tend to put on less weightApril 23rd, 2010 - 1:43 pm ICT by IANS
London, April 23 (IANS) A new study has linked nicotine poisoning with weight gain, and concludes that active smokers put on more weight than non-smokers.
Four years of analysis at the University of Navarra in Spain (UNAV) revealed that those who put on the least weight were those who had never smoked.
Researchers from the department of preventative medicine at UNAV in Spain have evaluated the link between the two cardiovascular risk factors: the ‘nicotine habit’ and the increase in weight when smokers stop the habit and when they continue smoking.
The results “are crucial for considering prevention programmes,” said Francisco Javier Basterra-Gortari, main study author and researcher at UNAV.
The data, resulting from an analysis of 7,565 people over 50 months, is based on age, sex, initial body mass index and lifestyles (sedentarism, changes in physical activity, energy/fibre intake, snacks between meals and consumption of fizzy drinks, fast food and alcohol).
Weight gain in people who stopped smoking during the study was higher the more cigarettes they smoked a day when the investigation began. Those who continued smoking also gained more weight during this period than the non-smokers.
The authors confirm that nicotine addiction is not an effective way of preventing obesity. “In fact the increase is demonstrated, especially in ex-smokers and in smokers who continue,” highlights Basterra-Gortari.
The association between being overweight and nicotine addiction is especially harmful for cardiovascular health. Therefore, abandoning the nicotine habit has been linked to a decrease in the risk of cardiovascular illnesses and cancer.
However, experts argue that weight gain after stopping smoking is, often, a reason for not quitting the nicotine addiction, especially among women, said a UNAV release.
Most of the investigations that have studied this link have observed that, although there is an increase in weight after quitting smoking, there are notable variations in weight gain.
These findings were published in the journal Revista EspaÃ±ola de CardiologÃa.
