Introduction. In recent decades the upsurge in research on human spirituality and health has been observed. The study of spirituality and its relationship to health is possible by assessing the level of internal development (maturity) of man as a person. The aim of the study is to determine the level of personal maturity of sick and healthy people and to establish its relationship to the integral conclusions about the functional state of the cardio-respiratory system. Material and methods. 560 people, men ⸻ 301 (53.75%), women ⸻ 269 (46.25%). Average age of the subjects ⸻ 35.00±17.75 (95% confidence interval: 33.52–36.47) years. There were 337 patients (60.18%) suffering from chronic diseases, and 223 ( healthy patients (university students) (39.82%). Height, body mass, heartbeat rate, respiratory rate, blood pressure, vital capacity, muscle strength of the hand were measured. The functional state of the cardio-respiratory system was assessed by integral indicators: adaptive potential of circulatory system according to A. P. Berseneva, level of physical state according to O. A. Pirogova, life index, Skibinski’s index, Kerdo index, hand strength index. To determine the levels of personal maturity, a survey was conducted by Jose Stevens. Applying the levels of maturity proposed by the author ("baby", "kid", "teenager", "young man" and "adult"), low, medium-low, medium- high, undifferentiated and combined levels of personal maturity were formed, which were considered degrees of human spiritual development. Results. 53.39% (299/560) of subjects had high levels, and 35.54% (199/560) - ⸻ low levels, including undifferentiated ones, of personal maturity. It was established that a predominance of high level of personal maturity took the place in the event of satisfactory adaptive potential of the circulatory system according to A. P. Berseneva, high level of physical state according to О. А. Pirogova, full compliance of respiratory function in relation to body mass according to life index, a higher level of interaction of respiratory and circulatory organs according to the Skibinski’s index, high relative strength of the hand and the normal state of vegetative tonus according to the Kerdo index. Conclusions. There is a significant relationship between the personal / spiritual maturity of man and the functional state of the cardio-respiratory system. People with high levels of personal / spiritual maturity have a better functional state of the cardio-respiratory system than people with low and undifferentiated levels.

Introduction. In recent decades, the influence of spirituality on human health has been researched. Currently, there are the data on relationship between spirituality/ religiosity and lifestyle of man too. However, these data are not always unambiguous and understandable, and they often have a contradictory character, which requires further research of this scientific problem. Aim is to establish the relationship between personal maturity of man and lifestyle. Material and methods. 560 persons, men ⸻ 301 (53.75%), women ⸻ 269 (46.25%). Average age of examined persons ⸻ 35.00±17.75 (95% confidence interval: 33.52–36.47) years. To determine the levels of personal maturity, a survey was conducted by method of Jose Stevens. Using the levels of maturity proposed by the author («baby», «kid», «teenager», «young man» and «adult»), the low, medium-low, medium-high, high, undifferentiated and combined levels of personal maturity were formed, which were considered stages of spiritual development of an individual. To characterize the lifestyle of the examined persons, the data on their physical activity in office, at the place of study and at home, regularity and activity on vacation / during outdoor games, spending their leisure time, alcohol consumption, attitude towards tobacco smoking, regularity of meals were collected through a survey. Results. 53.39% (299/560) of the examined persons showed high, and 35.54% (199/560) ⸻ low level, including the undifferentiated one, of personal maturity. A favorable dependence of the level of personal / spiritual maturity of man with some components of lifestyle was established, which is manifested in its direct correlation with the presence of physical activities on vacation /during outdoor games and inverse correlation with alcohol consumption and tobacco smoking. Lifestyle components such as performing regular physical exercises in office, at the place of study and at home, forms of spending leisure-time and keeping a proper diet are inversely related to the level of personal/spiritual maturity of an individual, which contradicts existing concepts of a favorable relationship between these components of the lifestyle of an individual and the level of his/her spirituality. Conclusions. There is a significant relationship between spiritual maturity of man and lifestyle. High levels of spirituality promote to physical activities on vacation / during outdoor games, reducing alcohol consumption and tobacco smoking.
