3. Introduction
• Mobile or cellular phones are now an integral part of
modern telecommunications.
• More than 200 countries were estimated to be using mobile
phones .
• There are approximately 4.6 billion mobile phone

8. Mobile phones and youth
• Mobile phone use has become nearly ubiquitous among
adolescents in the Sri Lanka.
• More than half of Sri Lankan’s population is under 25 years of age
and is at the forefront of mobile phone revolution.
• College-going and working young adults in Srilanka clearly
indicate that mobile phones play a crucial role in their life and
they use them for a variety of communication and media-related
activities such as accessing internet, news, messengers, facebook ,
listening to music and taking pictures.
• The growth of mobile phones in Sri Lanka and in particular their
popularity and use by young people in Srilanka is posing a high
risk to their health (Sri Lanka Journal of Child Health).

9. Mobile Phones and Health
• Medical researchers are concerned about the possible health
risks, even small ones ,as a result of the exposure to Radio
Frequency and microwave electromagnetic fields, have been
expressed since the introduction of mobile phones.
• The adverse health effects of radiofrequency fields are on
brain electrical activity, cognitive function, sleep, heart rate
and blood pressure due to over indulgence of mobile phones
(WHO study 'Electromagnetic fields and public health: mobile phones).
• The electromagnetic fields produced by mobile phones are
classified by the International Agency for Research on Cancer
as possibly carcinogenic to humans.

10. Rationale
In Sri Lanka there are about 20.3 million
mobile phone users, majority of which
belong to young age population, which are
also suffering from the harmful effects of the
same and are NOT aware about it. In our
study we will emphasize on the issues
leading to the these harmful effects and also
measure the youth responsiveness towards
this insidious problem.

11. Research Problem
• Impact of increased usage of Mobile
phone on the health of youth (15-25
years)

12. Research Questions
• What is the impact of the mobile usage on
the health of youth?
• What factors influence the increased use of
mobile phones among the youth?
• What is the youth responsiveness towards
the issue?

13. Objectives
Below would be the objective for to focus on the study
• to determine the impact of the increased use of mobile
phones on Youth’s health .
• to identify the factors that contributes to the increased use
of mobile phones among youth .
• The third purpose is to measure the awareness and
responsiveness about the increased use of mobile phones
and its harmful effects among the youth.
