Neck pain is one of the most common painful sensations caused by long-term retention of the head in one position, long-term stereotypical activity of the hands in front of the body, decreasing frequency of dynamic activities, and stress. In the last decade, we have witnessed the growing importance of mobile devices in our daily lives, especially in the lives of young people. There is a trend of daily multi-hour use of mobile devices for communication, entertainment and information. It is for these reasons that this research has the main goal, which is to examine whether there is a connection between the appearance of neck pain and the use of cell phones and tablets. 114 respondents from all counties in the Republic of Croatia participated in the research. Respondents filled out an online survey that was completely anonymous. The respondents were between 18 and 30 years old, and those older or younger were not taken into account. The research was conducted in 2022 in the summer period. The largest number of respondents is from the Varaždin County, and the most represented field of study is biomedicine and healthcare. 5 times more female than male respondents participated in the research. The median age of the respondents was 23 years. The research results show that 36.09% of respondents use a mobile phone or tablet for 5-6 hours daily, while 11% of respondents use it more than 6 hours a day. Almost half of the respondents have occasional pain in the neck, and 22.81% of them feel discomfort in the neck after using a mobile phone or tablet for several hours. The largest number of respondents constantly changes their position when using a mobile phone or tablet, while 26.32% of them take a specific "my position" that is most often irregular, with compensatory patterns and is bad for posture. Taking into account the objectives of the research and the set hypotheses, two hypotheses were rejected while the third proved to be true. Statistically significant data were obtained on students' daily activities and social life, defined through 6 areas of life. If this research were to be continued and expanded, it should be conducted on a larger sample in order to obtain more relevant results.
