ABSTRACT
Background: Smartphone usage is gradually escalating among Indian adolescents, which is having adverse consequences on their health and well-being. Awareness regarding adverse health impacts of smartphone usage among adolescents is thus necessary. Aims and Objectives: This study assessed the smartphone usage pattern and perception regarding its health effects among adolescents attending adolescent friendly health clinic (AFHC) at Medical College and Hospital, Kolkata. Materials and Methods: This cross-sectional study was conducted among 187 adolescents from January to March 2023 at AFHC of Medical College and Hospital, Kolkata selected by systematic random sampling technique. Pre-designed self-administered questionnaire was utilized for data collection. Data were analyzed using SPSS software. Factors associated with the duration of smartphone usage were analyzed using the Chi-square test. Results: Smartphone was used by all the study participants (n = 187). A significant proportion has utilized smartphones for >3-year duration, whereas 114 (60.9%) used them for 1–2 h per day and 56 (29.9%) used them for ?3 h per day. The major adverse health impacts of smartphone usage perceived by the participants were eye symptoms (64.2%), headache (50.8%), and neck pain (46.5%). Gender (?2=12.98, df = 2, P = 0.0012), type of residence (?2 = 7.98, df = 2, P = 0.018), and socioeconomic status (?2 = 34.96, df = 2, P < 0.001) were factors significantly associated with the duration of smartphone usage per day. Conclusion: Smartphone should be optimized to protect the physical and mental well-being of adolescents. Motivation and counselling regarding the adverse effects of smartphone usage is should be given the utmost priority. Generating awareness among parents at the community level through field health workers is also the need of the hour.
ABSTRACT
This study was a correlation study to analyze the effects of smartphone usage time on food choice perceptions and behavior in middle school students in Seoul areas. The subjects to be surveyed were middle school students attending junior high schools in Mapo-gu, Seoul. A total of 133, 102, and 102 students were in the first second, and third grades, respectively. The usage time of smartphones was the weekday and weekend usage time except for the call function. Food choice perception and its behavior as dietary habits were constructed referring to previous research and food balance wheels data for the correct dietary habits of the Ministry of Health & Welfare and Korean Nutrition Society. The food choice behavior was categorized into non-recommended food and recommended food. The results are summarized as follows. First, the longer the time spent on smartphones, the less favorable the perception of correct food choices. Second, the higher the dependence on smartphones, the less favorable the perception of correct food choices. Third, the correct perception of food choices has been shown to reduce food choices, known as non-recommended foods. In addition, proper perception of food choices has been shown to increase the choice of recommended foods. In conclusion, the usage time and reliance of smartphones of middle school students was found to affect the food choice behavior by lowering the perception of correct food choices. This research is expected to form the basis for the development of programs and educational materials that can be of assistance to adolescents who are experiencing difficulties.
