PROBABILITY OF NICOTINE ADDICTION DEVELOPMENT IN SMOKING FEMALE PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE, DEPENDING ON SMOKING HISTORY AND THE NUMBER OF CIGARETTES SMOKED

Introduction. This paper presents the results of assessing the likelihood of developing nicotine addiction, depending on smoking history and on the number of cigarettes smoked per day by women of fertile age. The aim is to establish the prognostic probability of nicotine addiction development in smokers, depending on smoking history and on the number of cigarettes smoked. Materiаls and Methods. The prospective study included 107 smoking female patients with chronic obstructive pulmonary disease and nicotine addiction of different stages (hereinafter referred to as nicotine addiction). The patients were divided into 2 groups, depending on their secondhand smoke: 53 smoking patients with and 54 smoking patients without secondhand smoke. The observational group consisted of 42 non-smoking women without any chronic diseases. Chronic obstructive pulmonary disease was diagnosed based on the clinical recommendations of the Russian Respiratory Society (2021). Reliability of the outcomes was assessed using the methods of parametric and nonparametric statistics. Prior to the application of all statistical research methods, we checked whether our sam- pling complied with the Gaussian (normal) distribution law. The distribution law was described using the Kolmogorov- Smirnov and Lilliefors normality criteria, and a single-sample Shapiro-Wilco normality test. Nonlinear links of binary features with quantitative or qualitative features were evaluated using logistic regression. Logistic regression analysis made it possible to create a statistical model for predicting the probability of an event based on available data. Results and Discussion. With an average smoking activity of 14 cigarettes per day, the onset of nicotine addiction in the first group (a combination of active and secondhand smoke) began with the smoking experience of 12 years, reaching the maximum probability with the experience of 15 years. In the second group, nicotine addiction appeared and reached its maximum (100 %) four years later than in the first group. With an increase in the number of cigarettes up to 16 per day, an identical pattern was observed within the course of earlier nicotine addiction. Conclusions. Secondhand smoke, in addition to active smoking, increases the nicotine load with the development of more pronounced prerequisites for the pathogenetic processes of chronic obstructive pulmonary disease development.
