RESUMO
INTRODUCTION: Mobile phone dependence has become an emerging public health problem. This cross-sectional study was conducted to find out the mobile phone involvement and dependence among undergraduate medical students in a Medical College of West Bengal, India. MATERIALS AND METHODS: A study was conducted at IQ City Medical College, Durgapur, District Burdwan, West Bengal, India, during July-August 2015 among 252 undergraduate medical students. Involvement and dependence were elicited by mobile phone involvement questionnaire (MPIQ) and mobile phone dependence questionnaire (MPDQ), respectively. Statistical Package for the Social Sciences (SPSS) software (version 19.0) was used for analysis. RESULTS: About 14.9% of students were being highly involved with their mobile phone. The mean score of MPIQ was greatest in domain 5, i.e. euphoria followed by domain 2, i.e. behavioral salience and then domain 4, i.e. conflict with other activities. About 19.4% of males and 11.1% of females had high dependence. Mean MPDQ score was higher among males, though it was not significant statistically. Sex, total recharge, and total hours spent on mobile phone could explain between 2.2% and 3.8% variance of the presence of dependence in binary logistic regression. Total recharge (adjusted odds ratio 1.144) and total hours spent on mobile (adjusted odds ratio 1.135) were positively associated with the presence of dependence. CONCLUSION: Many students were highly involved and dependent on mobile phone and they had already been experiencing some health-related problems. There is a need to identify students having high involvement and dependence so as to generate adequate awareness and plan educational or treatment interventions accordingly.
