Impact of problematic mobile phone use among nursing students in India: Exploring associations with depression, insomnia, self-esteem and satisfaction with life

AIM

This research aimed to determine the impact of problematic mobile phone use on negative mental health outcomes among nursing students in India, highlighting the necessity for targeted interventions and support mechanisms to enhance the overall well-being and adaptability of future healthcare professionals.

METHODS

A cross-sectional survey was conducted in three randomly selected nursing colleges in South India, employing validated and standardized tools such as the Mobile Phone Problematic Use Scale, Patient Health Questionnaire, Insomnia Severity Index Scale, Satisfaction with Life Scale and Rosenberg Self-Esteem Scale.

RESULTS

The study included 402 nursing students with an average age of 20.47 years, revealing a 39% prevalence of severe problematic mobile phone usage. Positive correlations were observed between mobile phone problematic use and age, depression and insomnia. Additionally, strong negative correlations were found between satisfaction with life and self-esteem. Depression and satisfaction with life served as chain mediators in the impact of self-esteem on problematic mobile phone use, and both self-esteem and satisfaction with life negatively predicted problematic mobile phone use.

CONCLUSION

The study highlights a prevalent issue of problematic mobile phone use among nursing students, indicating a pressing need for timely intervention, as it correlates with depression, sleep insomnia, low self-esteem and life dissatisfaction.

Knowledge and attitudes towards and prevalence of overweight and obesity among undergraduate students at Universiti Kuala Lumpur Royal College of Medicine: A cross-sectional study

Introduction

Overweight and obesity pose significant health risks, affecting social and economic well-being and potentially hindering mental health and learning outcomes. This study investigated the knowledge, attitudes, and prevalence of overweight and obesity among undergraduate students at Universiti Kuala Lumpur Royal College of Medicine (UniKL RCMP), Malaysia.

Methods

A total of 351 UniKL RCMP undergraduate students participated in this study. Descriptive analysis was used to evaluate the sociodemographic and educational profiles of respondents. The chi-square test was conducted to identify the relationship between the sociodemographic and educational profiles and the level of knowledge and attitudes towards overweight and obesity.

Results

The prevalence of overweight and obesity was 25.4%. The majority of the respondents possessed a good level of knowledge regarding overweight and obesity (n=316, 90%). The respondents' programme was significantly associated with their level of knowledge (P=0.001).

Conclusion

This study provides important information to university authorities, students, lecturers, parents and other stakeholders in education and health sectors about the impacts of overweight and obesity on the physical, social and academic welfare of university students.

The associations between screen time and mental health in adolescents: a systematic review

BACKGROUND

Adolescents have extensive use of screens and, they have common complains related to mental health. Here a systematic review was done to understand the association between screen time and adolescent's mental health.

METHOD

This review was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA. An update search was performed in January 2023 with the following keywords: "screen time," "adolescent," and "mental health" on PubMed, PsycINFO and Scopus databases.

RESULTS

50 articles were included, most have found associations between screen exposure and mental health in adolescents. The most used device by adolescents was the smartphone and the use on weekdays was associated with diminished mental well-being. Social media use was negatively associated with mental well-being and, in girls, associated at higher risk for depression.

CONCLUSION

Excessive screen time in adolescents seems associated with mental health problems. Given the profusion and disparity of the results, additional studies are needed to clarify elements such as the screen content or the interaction of adolescents with different screen devices.

The Effect of Human Development Index on Obesity Prevalence at the Global Level: A Spatial Analysis

Background

Obesity is one of the major public health concerns, and its prevalence is increasing worldwide. This study aimed to investigate the effect of human development index on the prevalence of obesity across 152 countries.

Methods

Country-level data on obesity prevalence and its influencing variables related to 152 countries were obtained during 2000-2019 from several sources. A Spatial Bayesian Hierarchical model was employed in this research, and the analyses were performed using R statistical software (version 3.6.1).

Results

We found a positive relation between HDI and obesity prevalence, in such a way if low HDI countries advance to high HDI countries, the obesity rate is expected to increase significantly by 7.45%. Moreover, the association between obesity prevalence and the percentage of people aged 40-59 (β=0.07), urbanization rate (β=0.11), percentage of internet users (β=0.01), percentage of alcohol users (β=0.16), milk consumption per capita (β=0.15) and Percentage of depression (β=0.58) was significantly positive. Conversely, per capita consumption of fruits and vegetables (β=-0.15), and smoking rate (β=-0.02) was negatively associated with obesity prevalence.

Conclusion

The prevalence of obesity is growing across all countries, especially in the countries with high and very high HDI. Therefore, policymakers must also pay attention to the negative effects of development when trying to improve the welfare of society.

Problematic Mobile Phone Use and Life Satisfaction Among University Students During the COVID-19 Pandemic in Shanghai, China

Objective

This study examined problematic mobile phone use (PMPU) and its relationship with life satisfaction in Chinese university students during the pandemic.

Methods

An anonymous online survey was conducted in a university in China. The Mobile Phone Addiction Index (MPAI) and the Satisfaction with Life Scale (SWLS) were used to assess the severity of problematic mobile phone use and life satisfaction, respectively. Data on demographic and health-related factors were also collected.

Results

A total of 1,491 undergraduate students (73.3% were male) completed the survey. On average, students in the survey reported spending 7.4 ± 4.3 h/day on phone use. Their MPAI score was 38.1 ± 13.3 and SWLS score was 24.9 ± 6.8, respectively. After controlling for confounding factors, the MPAI score was significantly associated with lower life satisfaction. Multiple linear regression revealed that higher monthly allowances, frequent insomnia, longer phone use duration were significantly associated with PMPU.

Conclusion

University students in China spend nearly half of their waking hours on mobile phone use, significantly longer than before the COVID-19 pandemic. PMPU is associated with insomnia, lower life satisfaction and higher allowances. If the trend continues after the pandemic, interventions may be needed. Increase in-person interactions, limiting online social and gaming time, awareness campaign may be effective in reducing the impact of PMPU and improve life satisfaction.
