Adverse health effects and unhealthy behaviors among dental undergraduates surfing social networking sites

INTRODUCTION: Little is known about the relationships between adverse health effects and unhealthy behaviors among dental undergraduate students surfing social networking sites (SNSs). OBJECTIVES: The aim of this study was to determine the associations between adverse health effects and unhealthy behaviors with social networking usage among dental students. MATERIALS AND METHODS: A cross-sectional study was conducted in a private university in Madhya Pradesh (India) among 300 dental undergraduate students. A self-administered questionnaire was used. It included questions on sociodemographical data, pattern of social networking use, social relationship, unhealthy behaviors, and health effects. RESULTS: The mean age was 21.5 (±2.3) years. The average daily SNSs surfing hours were 3.5 (±1.8). Significant associations were found between average hours of social networking and the following factors: isolation from family members and society, refusing to answer calls, musculoskeletal pain, headache, and eye irritation (P < 0.001). The average hours spent on social networking were significantly associated with holding urination and defecation while online, surfing SNSs until midnight, and postponing, forgetting, or skipping meals (P < 0.001). Cohen's effect size value between adverse health effect and social networking hours were 0.78, 0.86, 0.82, 0.86, and 0.81 for back pain, shoulder pain, wrist pain, headache, and eye irritation, respectively. The effect size value between health-related behaviors and social networking hours were 0.72, 0.62, 0.72, 0.71, and 0.84 for holding urine, holding defecation, postponing meal, skipping meal, and social networking until midnight, respectively. Gender-wise comparison for social networking hours showed a low practical significance (d = 0.09). CONCLUSIONS: The average hours spent on social networking were associated with adverse health effects and unhealthy behaviors among dental undergraduate students, as well as social isolation from the family and society.
