Impact of habitual smoking on the organism of adolescents living in the north of Russia

The aim of the work is to analyze the impact of habitual smoking on the physiological systems of adolescents living in the north of Russia (65° N). Materials and Methods. Using generally accepted methods, morphofunctional, physiometric, physiological and psychological parameters were determined in 34 boys aged 14-15 years (11 smokers for at least 2-3 years and 23 non-smokers). The level of physical health was assessed according to Apanasenko method. Results. Compared with non-smokers, smoking adolescents have statistically significantly higher body weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean blood pressure (MBP) during exercise, heart rate (HR) during exercise and its increase while working, HR recovery after exercise (Martine-Kushelevsky test), rate pressure product (RPP), and scores of activity (WAM questionnaire). At the same time, they demonstrated lower strength index (SI), maximum expiratory pressure (MEP), vital capacity (VC), vital index (VI), Skibinskaya index (SI), level of physical health (LPH), and WAM parameters. Smokers, compared to 11 non-smokers of the same weight, have statistically significantly lower height, strength and SI, Genchi test time, MEP, VC, VI, SI, LPH, and scores of well-being and mood (WAM parameters). However, they have higher HR during exercise, its increase while working, and HR recovery. Excess body weight in smokers leads to hypertension, while long-term smoking in teenagers living in the north of Russia causes physiological decline and physical health deterioration. In some cases, our results (decrease in strength, Genchi test time, VC, VI, increased HR, hypertensive reactions, and health deterioration in smokers) correlate with the data obtained both in our country and abroad.
