Abstract
INTRODUCTION: The mobile phone has evolved into an indispensable accessory carried by everyone. With its increasing usage, there is a parallel rise in mobile phone addictions. Nomophobia, short for no mobile phone phobia, is characterized as a fear specific to the absence of mobile phones. OBJECTIVES: (1) To assess the prevalence of nomophobia among adolescents and adults residing in semi-urban Chennai. (2) To understand the patterns of mobile phone usage and explore the health-related consequences of nomophobia. METHODS: This cross-sectional study was conducted among adolescents and adults (15-50 years) in semi-urban Chennai from July to September 2022. The sample size was 220, and the study utilized the Test of Mobile Phone Dependence Brief as an assessment tool. Participants scoring >30 were identified as nomophobic, indicating mobile phone dependence. RESULTS: Among the 220 study participants, there was an almost equal distribution between males and females, with a majority falling within the 21-25 age group. Approximately 26.1% belonged to the upper middle class and 89.1% were married. The prevalence of nomophobia was notably high at 68.6% (151 out of 220). A significant association was found between social class and mobile phone addiction, with the middle class exhibiting higher levels of addiction. CONCLUSION: The study highlights that a substantial majority of adults exhibit mobile phone addiction, almost two-thirds of the participants. There is a pressing need for health awareness programmes targeting adults to educate them about the adverse effects of mobile phone addiction. Additionally, reinforcing strategies for effective and time-restricted mobile phone usage is essential.
