The results of this study are important in a number of areas:
First, they provide university students with fundamental
information and advice on their use of smartphones. Second,
the data shows that the size of the LCD screen is closely
correlated with pains in specific body regions. Third, the
amount of time that a smartphone is used is also correlated
with pain. This study has limitations in that it is not representative
of the whole population, as it specifically focused
on university students. Additionally, it should be noted that
a self-administered questionnaire does increase the risk of
response bias.
