Does Daily Smoking by Adult Men Affect Weight? Results of the WOBASZ II Program

Summary/Abstract: Many epidemiological studies reveal that tobacco smokers have lower body weight than never-smokers. There are no studies on the effect of tobacco smoking on body in Polish adult men populations. The aim of the study was to analyse the effect of everyday smoking on body weight in Polish adult population of men. The study is a cross-sectional epidemiologica lstudy (with control group). The study material was results of the Multi-center National Population Health Examination Survey – WOBASZ II, a randomized trial, conducted in the period 2013–2014 on Polish population, aged 20–74 years. The study group included respondents-males who have smoked at least 1 cigarette a day for above a year. The control group consisted of never-smokers (did not smoke in the study period and before – for at least a year). Both the study and control groups consisted of 339 males. The Propensity Score Matching (PSM) statistical method, involving the selection of the nearest neighbour, was used to create the study andcontrol groups. The average body weight and the average BMI in male smokers from the studied group were lower than in the control groups. The difference in the body weight of the males who had never smoked and those who had been daily smokers was 3.3 kg (p<0.05). Inyoung smokers, (<20-34> years), the above body weight parameters were not statistically different between the study and control groups. Overweight or obesity were observed statistically less frequently in male smokers (in comparison to never-smokers). These males had statistically more frequently normal body weight. In the studied males, a BMI growing trend was accompanied by a decrease in the number of cigarettes smoked daily. Conclusion: Lower body weight observed in daily smokers and confirmed in this study, particularly in males, in comparison withnever smokers, cannot be an encouragement to smoke tobacco, neither to get into the habit of smoking nor to continue smoking. With regards to young adults, I did not confirm the common belief that body weight of smokers is lower than that of never smokers.
