INTRODUCTION

Social networks are those open platforms and have certain characteristics such as their own profile, a public list of contacts and continuous exchange of content¹, these are divided into different types according to the desired objective of the user, for example we have social networks of relationships. such as Instagram, Twitter, Tinder, Facebook and entertainment social networks, these are YouTube, Pinterest and TikTok². The adolescents and young adults of this generation were born alongside the rise of technology and are growing with the innovative proposals offered by social networks, and just as this new virtual world can have a positive influence, its inappropriate use can affect mental health.³. In Peru, between 2020 and 2021, it was estimated that 78% to 80% of the population between 18 and 70 years old connect to the internet with the main objective of using social networks (77%), followed by conversations through chats (70%) and studying (67%); furthermore, the three platforms most used by Peruvians during the quarantine were WhatsApp, Facebook and YouTube^4-6.

In the new era of coronavirus 2019 (COVID-19), the internet and social networks have become an indispensable element for education, work and entertainment, facilitating numerous activities of daily life. The student population being the most exposed group due to the new virtual learning method due to the mandatory isolation and temporary closure of schools and universities as occurs in many countries^7,8. For medical students, the implications of addiction to social networks can hinder their studies and impact their long-term professional goals, having harmful consequences for society, since excessive use of these can easily distract students, harming memory and making it difficult to remember what they are learning, it also directly affects the mood and quality of sleep, this could influence future health professionals not to provide adequate quality of care to the population^9,10.

Studies have been carried out in different countries on the effect of social networks, showing that prolonged use of platforms such as Facebook can be related to signs and symptoms of depression, anxiety and stress³. Likewise, an investigation in Peruvian university students determined a significant relationship between addiction to social networks with depressive symptoms and poor quality of sleep⁹. Hou Y, et al (2019) found that addictive use of social media was common among college students and was associated with poor mental health and poor academic performance¹⁰.

For all these reasons, the objective of this research was to search for the association between addiction to social networks and mental health in human medicine students, such as depressive symptoms, anxiety, stress and sleep quality.

MATERIALS AND METHODS

RESULTS

In total, 454 surveys were analyzed, 65.4% (n=297) were women, the age range 17 to 21 years and third academic year are the most predominant groups. 49.1% (n=223) of students had a medium level of addiction, followed by low addiction with 41% and 9.9% had a high level of addiction. In addition, 40.5% (n=184) have poor mental health, 57.5% presented depression, 56.4% anxiety, 70.5% stress and 77.3% poor sleep quality. Regarding family relationships, 18.5% had a bad relationship with parents and 17.7% had a bad relationship with siblings (Table 1). The most used social networks were WhatsApp (93%), Instagram (70%) and in third place YouTube (64%).

According to the bivariate analysis of mental health, depression, stress, anxiety and sleep quality

In human medicine students, the risk of poor mental health in the group with social media addiction was high (95% CI: 1.92-3.50) and medium (95% CI: 1.26-2.17) 159% and 65% higher compared to the low level of addiction, in addition, poor relationships with parents and siblings were risk factors for mental health; besides, male sex (95% CI: 0.58-0.96) was a protective factor (Table 2).

The risk of depressive symptoms in human medicine students who have a high (95% CI: 1.69-2.60) and medium (95% CI: 1.35-2.01) addiction to social networks was 109% and 65% higher compared to the low level of addiction, also the poor relationship with parents (95% CI: 1.17-1.61) and with siblings (95% CI: 1.04-1.49) indicated to be factors of risk; male sex (95% CI: 0.66-0.95) was a protective factor for depressive symptoms (Table 3).

The risk of anxiety in students with high (95% CI: 1.95-2.93) and medium (95% CI: 1.37-2.08) addiction levels was 139% and 69% higher than students with low addiction, in addition, the bad relationship with parents (95% CI: 1.17-1.62) was 38% higher compared to those who have a good relationship and the male sex turned out to be a protective factor (Table 4).

The risk of stress in human medicine students due to high (95% CI: 1.39-1.91) and medium (95% CI: 1.21-1.62) social media addiction was 63% and 40% higher than those with a low level of addiction, a poor relationship with parents and siblings represented a 23% greater risk of stress and male sex was a protective factor (Table 5).

Finally, the risk of poor sleep quality in students with addiction to social networks was found to be high (95% CI: 1.11-1.46) and medium (95% CI: 1.04-1.30) at 27%. and 16% higher compared to the low level of addiction, also the poor relationship with parents determined 16% higher risk. (Table 6).

According to the multivariate analysis of mental health, depression, stress, anxiety and sleep quality

This analysis showed that high (95% CI: 1.78-3.31) and medium (95% CI: 1.20-2.09) addiction to social networks determined a 142% and 59% higher risk for poor mental health than students with a low level of addiction. Male sex was statistically significant (Table 2). The high and medium level of addiction to social networks showed a 99% and 59% greater risk of presenting depressive symptoms compared to low levels of addiction; while a poor relationship with parents indicated a 22% risk (95% CI: 1.02-1.46) and male sex (95% CI: 0.67-0.94) was a protective factor for depressive symptoms (Table 3). High and medium social network addiction had a 129% and 68% higher risk of presenting anxiety than in students with a low level of addiction, and male sex (95% CI: 0.65-0.92) was a protective factor for anxiety (Table 4). Addiction to high and medium social networks was 55% and 37% higher risk for presenting stress, and poor relationships with siblings represented a 16% risk. Furthermore, male sex was a protective factor (Table 5). High and medium addiction to social networks had a 25% and 15% greater risk of presenting poor sleep quality than in students with a low level of addiction and male sex was a protective factor (Table 6).

DISCUSSION

During recent years, the use of social networks has increased significantly, especially since the beginning of confinement due to the COVID-19 pandemic. This increase was for social reasons such as maintaining contact or establishing new links, also due to the need to regulate humor with the search for entertaining videos or images, the need to be informed, the construction of a personal identity or the expression of opinions¹. Various investigations, as well as this one, show that its excessive use is correlated with worse mental health outcomes, with the university population being the most affected group, as they face stressors such as the interruption of their education, concern about virtual learning, social isolation, financial worry and uncertainty about their future^19,20.

Mental health is a topic of global interest. In a multinational literature review, it was found that excessive use of social networks was a significant predictor of acute stress and anxiety symptoms. These results suggest that social networks may have a negative influence on mental health. short- and long-term mental health¹⁹. Our research had similar results, evidencing a significant correlation between these variables. Likewise, a study carried out on university students in Indonesia found that higher social media addiction scores are associated with poor mental health¹⁰. The popularity of networks is growing, but there is still not much research, so despite the known negative effects such as dropping out of studies, insomnia, depression, poor academic performance, among others, we still do not know to what extent it can affect mental health²¹.

Among the most common comorbid disorders is depression. Research carried out in Paraguay and Peru on university students shows a statistically significant relationship between addiction and depressive symptoms^11,22. The present research shows that students with high levels of addiction to social networks are more likely to present depressive symptoms than those with low levels of addiction, similar to the study by Sujarwoto et al.²³where students with higher social media addiction scores were more likely to experience depression. This result is probably because the majority of information and publications observed on social networks contribute to egocentrism and consumerism, influencing unrealistic living standards or physical aspects of people; In addition, we have the famous fake news, that is, false news that seeks to generate a strong emotional response²⁴.

Greater use of social networks is directly linked to anxiety because students have persistent thoughts about their use and at the same time they waste time being connected in the virtual world. The results obtained by Verónica P. et al (2020), as in our research, determined that students with a greater addiction to social networks presented a higher level of anxiety²⁵. In times of COVID 19, it is understandable that university students increase their use of time on social networks, causing a possible increase in the risk of presenting anxiety, which is why students must strictly control the time they dedicate to the use of social networks²⁶.

Since the beginning of the pandemic, students have faced new stressors such as the restriction of outdoor physical activities and the change from in-person to virtual learning, impacting their psychological well-being²⁰.Our study detects around 70% of students presented stress during their virtual learning in 2021. Regarding addiction to social networks and stress, a study carried out in China (2021) shortly after the start of the pandemic found that excessive use of social networks >3 hours a day is significantly associated with acute stress¹⁹. Likewise, our study shows a greater risk of presenting stress the higher the level of addiction to social networks. The stress experienced by students can affect their learning results, therefore we must achieve its reduction through the selection of effective coping strategies, both mental and behavioral, to control, tolerate or reduce stressful events²⁰.

Excessive use of the Internet could significantly influence the sleep and wake schedule, causing insomnia and other sleep disorders²⁷, In this study, 77.1% presented poor quality sleep. This result is similar to previously developed research. in medical students in Saudi Arabia where the prevalence was 76%²⁸and in a private university in Peru it was 72.4%¹², these high percentages may be due to the excess of courses, extracurricular activities, the demand for high performance and long study time that the career demands. Likewise, a significant association was found between addiction to social networks and poor quality of sleep. This result supports previous research such as that of Zaheer H. and Mark D. (2021). In a study with 638 participants, positive correlations were obtained with poor quality. of sleep p < 0.01²⁹. Wong et al.⁽³⁰⁾in their research carried out on undergraduate and graduate student’s states that there is a significant association between the social media addiction scale and poorer sleep quality. Some mechanisms described to disrupt sleep are psychological stimulation (excited mood due to the use of social networks), light-emitting screens (light can suppress hormones that promote sleep, such as melatonin), and reduction in duration. of sleep⁽³⁰⁾.

One of the limitations of the research was the impossible identification of a causal relationship between the variables of interest due to their transversal characteristic. Another limitation was not obtaining a large amount of background information because the majority of studies were based on Internet addiction. Differences between gender were examined because our female population was older than males, in addition, students were not evaluated for previous mental illnesses before conducting the survey and we also faced a possible bias in the procedure during the resolution of the instruments since they had many questions. Likewise, we have the opportunity to conduct new research and learn more about the consequences of social media addiction when in-person classes resume in order to compare with those who were in virtual classes.

It is recommended for future research to conduct a prospective multicenter study. In addition, it is suggested that universities schedule virtual conferences on the topic of addiction to social networks, with qualified specialists (psychiatrists and/or psychologists) who teach and raise awareness among students about the harmful consequences that this can have on their health and well-being. academic life, in addition to providing a support plan.

Finally, we conclude that there is a statistically significant association between addiction to social networks and mental health (depressive symptoms, anxiety, stress and sleep quality) in human medicine students. Likewise, individual characteristics such as male sex and poor relationships with parents and siblings are significant and are associated with mental health.
