Sociodemographic factors influencing the level of physical activity in the respondents assessed using the RM42 accelerometer.
In order to search for a relationship between the accelerometer data and sociodemographic variables, the Mann-Whitney test was performed to check the relationship with gender and place of residence, and Spearman's rho correlation analysis was performed to check the relationship with other variables.
First, the differences between the genders in terms of accelerometer variables were verified. The results of the analysis are presented in Table 3.

LPA – low intensity physical activity; MVPA – moderate intensity physical activity; VPA – high intensity physical activity; PA0-5 – physical activity from 0 to 5 minutes; PA5-10 – physical activity up to 10 minutes; PA10+ – physical activity over 10 minutes; Steps – number of steps.
The analysis showed statistically significant differences between women and men in terms of moderate-intensity exercise (MVPA) and physical activity lasting more than 10 minutes (PA10+). It turned out that women were characterized by significantly longer daily time of moderately intensive physical activity, and longer time of physical activity above 10 minutes compared to men. In terms of the remaining variables, no statistically significant differences between the sexes were noted.
The next correlation that was checked was whether there was a difference between the physical activity undertaken by rural and urban residents with regard to the accelerometer data. The results of the analysis are presented in Table 4.

The analysis did not show any statistically significant differences between city dwellers and rural dwellers with regard to the accelerometer measurement results, which indicates that, regardless of the place of residence, the subjects showed similar physical activity parameters.
The next examined correlation was the connection between physical activity and age, education and health status of the respondents. The results of the analysis are presented in Table 5.

The analysis showed statistically significant negative correspondence between age and moderate and vigorous exercise (MVPA, VPA), as well as the number of steps (Steps). The results also indicated statistically significant positive correlation between age and light physical exercise (LPA). Weak positive correlations were observed between the education degree and physical activity up to 5 min (PA0-5). It also turned out that with the increase in the subjective assessment of health, moderate and vigorous physical activity (MVPA, VPA), physical activity above 10 min (PA10+) and the number of steps decreased.
Sociodemographic factors influencing the level of physical activity of respondents in the studies conducted using the GPAQ questionnaire
In order to compare the results of the objective (accelerometer) and subjective (GPAQ) studies, it was checked whether there was any correspondence between the data from the GPAQ questionnaire and the sociodemographic variables of the examined persons.
For this purpose, the Mann-Whitney test was used to check the relationship with gender and place of residence, and Spearman's rho correlation analysis was used to check the relationship with other variables.
First, the differences between the genders in the questionnaire variables were verified. The results of the analysis are presented in Table 6.

The analysis of the results obtained from the GPAQ questionnaires showed statistically significant differences between women and men in terms of such variables as the length and frequency of intensive and moderate physical effort at work (WorkVigDays, WorkVigMinDay, WorkModDays, WorkModMinDay), the length and frequency of intensive physical effort during sports (SpostrVigDays, SportsVigMinDay), as well as MET-min/week. It turned out that in each of the recorded cases, women were characterized by significantly higher values of the indicators compared to men.
Next, it was checked whether there were any differences between rural and urban residents in terms of physical activity declared in the GPAQ questionnaire. The results of the analysis are presented in Table 7.

The analysis showed statistically significant differences between the physical activity of urban and rural residents. It turned out that urban residents were characterized by significantly higher values in terms of the frequency and length (duration) of active getting around/movement, compared to rural residents. In the case of the remaining analyzed variables, no statistically significant differences were noted, which means that regardless of the place of residence, the respondents showed similar declared parameters of physical activity.
The next verified correlation was the existence of relationship between the physical activity results from the GPAQ questionnaire and age, education and health status. The results of the analysis are presented in Table 9.

The results revealed statistically significant negative relationships between age and the duration and frequency of intense physical activity (SportsVigDays, SportsVigMinDay). A similar trend was observed between documented education and the frequency and duration of moderate physical activity at work (WorkModDays, WorkModMinDay) and the metabolic equivalent value (MET).
The analysis also showed statistically significant positive relationships between documented education and the frequency and duration of intense physical activity during sports (SportsVigDays, SportsVigMinDay).
It also turned out that with an increase in the subjective assessment of health, the frequency and duration of intense physical activity increased (SportsVigDays, SportsVigMinDay).
In the case of the remaining pairs of variables, no statistically significant relationships were noted. It is also worth noting that the observed correlations mostly turned out to be weak and moderately strong.
