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).

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.

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.

Research Problem
