1. Introduction
Worldwide, social media use has rapidly increased over the past decade [
1]. On average, people worldwide spend approximately 2.5 h per day on social media and use over seven different social media platforms each month. In the Netherlands, this trend is also visible, where social media are particularly popular among young people [
2]. A clear generational divide in media use is evident, with traditional media such as printed newspapers and television seeing a decline [
3], while high-visual social media platforms like Snapchat and Instagram are seeing increased usage among young people [
4].
The increase in social media use is also reflected in the rise of problematic social media use in the Netherlands, especially among primary-school girls, which saw a more than twofold increase from 2017 to 2021 [
5]. Problematic social media use characterizes individuals who experience addiction-like symptoms as a result of their social-media use [
6]. It is different from excessive use of social media, typically defined solely on the basis of the hours of use [
7]. Examples of detrimental effects that can occur as a result of preoccupation with and compulsion toward excessively engaging in social media platforms are feeling restless, stressed, or irritated when (not) having access to social media, or neglecting other tasks to spend more time on social media. In primary schools, 18.1% of eighth-grade students reported being in contact through social media throughout the day, and about 30% reported that they frequently could not think about anything other than their next social media session. Additionally, over 40% admitted to using social media often as a means of avoiding unpleasant thoughts, while 12.5% reported regularly having arguments with others about their social media usage [
5].
Reasons for early adolescents to use social media are, for example, to connect with friends and family, fit in, feel happy, or reduce stress [
8,
9,
10]. Although there are some positive associations with using social media, numerous studies also report on the downsides of social media use, since problematic social media use has been associated with worse mental health and well-being [
11,
12]. Possible explanations for this relationship include the risk of being cyberbullied; social comparison; observing triggering posts, and the prevalence of filtered images on social media platforms, which can be harmful for body image and self-esteem [
13,
14,
15].
Despite extensive research on the association between social media use and mental health, several knowledge gaps remain. For example, the relationship with physical health complaints, such as having a headache or backache, has not been thoroughly explored [
16,
17]. For instance, poor posture while using social media on electronic devices, along with exposure to (blue) light, may lead to physical health issues. Additionally, if social media use negatively affects mental health, it may also have consequences for physical health [
18]. Furthermore, a decline in mental and physical health could lead to reduced life satisfaction.
Given the frequent use of social media, gaining insights into these associations is crucial, especially since reported psychosomatic complaints among primary-school students have increased over the past years [
5]. This raises the question whether the increase in social media use is a possible explanation for the increase in psychosomatic complaints. It is especially important to explore this relation in primary-school students, since habits are already formed at a young age [
19], and if problematic social media use is related to adverse health consequences, this might also impact their health later in life [
20]. Moreover, both mental and physical health are important for educational performance [
21,
22,
23]. An unfavorable association with problematic social media use would not only have implications for early adolescents’ health, but likely also for their academic career.
Additionally, although the relationship between social media use and mental health has been examined and observed in many studies, there is a significant knowledge gap regarding factors that might influence the impact of social media use [
24]. It is possible that the impact of social media use varies depending on individual characteristics, e.g., sex, as these might moderate its influence, resulting in varying effects for different people. Another moderating factor might be perceived social support, since evidence shows a negative relation between perceived social support and psychosomatic complaints [
25,
26]. For somatic complaints, the negative association with perceived social support is mainly explained by the mediating role of depressive symptoms and emotional self-efficacy [
27]. The positive association between perceived social support and psychosocial health can be partly explained by better self-esteem [
28]. Attachment theory research emphasizes the importance of emotional bonds between caregivers and their children, traditionally focusing on parent–child relationships. Teachers often serve as secondary attachment figures, providing emotional security and support when parents are absent. These attachment-like bonds with teachers can significantly contribute to children and young adolescents’ emotional and developmental outcomes, complementing the primary attachments formed with parents [
29]. This connection between social support and both mental and physical health prompts the question whether social support could moderate the potential negative effects of social media use. Perceived high social support may serve as a buffer against the potential negative effects of social media use, so that early adolescents with strong social support may experience less psychosomatic complaints compared to those with low perceived social support.
A deeper understanding of these links is needed to equip schools, policymakers, and other stakeholders with relevant information, and to support them in decision-making regarding social media. Therefore, to contribute to the existing literature on the impact of social media use, we aimed to answer two research questions: (1) To what extent is problematic social media use related to well-being, operationalized as having psychosomatic complaints and general life satisfaction, in primary-school students in the Netherlands? (2) To what extent are these relationships moderated by perceived support from family, friends, teachers, and classmates, and sex at birth? We hypothesize that problematic social media use is negatively associated with well-being, but that the associations are weaker in students who perceive high social support from family, friends, classmates, or teachers. For sex at birth, we hypothesize that associations are stronger for girls.
4. Discussion
The aim of the current study was to examine to what extent problematic social media use is related to psychosomatic complaints and general life satisfaction among primary-school students in the Netherlands, and whether the association differs depending on perceived social support. We found that problematic social media use was associated with all included outcomes, i.e., having a headache, stomachache, backache, feeling unhappy, having a bad mood or feeling irritated, feeling nervous, feeling dizzy, feeling nauseous, having concentration difficulties, having trouble falling asleep, sleeping bad, daytime fatigue, and general life satisfaction.
The ORs ranged from 1.70 for feeling dizzy to 3.08 for having a bad mood or feeling irritated, indicating that there were small-to-medium associations [
40]. This indicates that students who score one point higher on the scale for problematic social media use are more than three times as likely to report having a bad mood or feeling irritated multiple times a week. Overall, it appears that students who score higher on problematic social media use have both lower mental and physical health. These results are particularly concerning when considering the young age of our study population. Childhood is an important period for habit formation and learning [
19], and health conditions experienced during this stage can track into adulthood [
20]. Moreover, it was noteworthy that for the complaints that were least frequently reported, i.e., feeling nauseous and having a backache, we identified the strongest association with problematic social media use, besides having a bad mood or feeling irritated. While causal mechanisms cannot be implied from our analyses, it is worth exploring in future studies whether problematic social media use might indeed contribute to the occurrence of rare psychosomatic complaints in this age group.
Our findings are consistent with the existing literature. Previous studies also identified significant negative associations between social media use and multiple outcomes, such as mental health, sleep quality, and headaches [
17,
41]. While the study of Alonzo et al. [
41] focused on youth aged 16 years and older, our study confirms that social media use is also associated with psychosomatic complaints in younger age groups, and this finding has implications for prevention policies. The review by Bozzola et al. [
18] included mostly studies that focused on mental health, while only three out of the sixty-eight included studies included headache as an outcome. One of the explanations for having more trouble falling asleep and sleeping bad is that using electronic devices before bedtime can negatively influence the production of melatonin [
42]. Sleep disturbance can in turn cause daytime fatigue, but is also related to multiple mental health disorders, such as depression [
43]. Additionally, many social media platforms are designed to promote addictive behavior [
44], therefore probably causing students to spend more time on social media than intended. This extended time spent on social media, combined with improper posture during the use of devices to use social media might cause backaches and headaches [
45]. A qualitative study among adolescents with depression highlighted the potential risks of social media for worsening well-being. Factors that were discussed were observing positive posts of others, e.g., seeing others hanging out or having fun together; social comparison; triggering posts; or the risk of oversharing, which may lead to being cyberbullied or feeling embarrassed [
14].
It is noticeable that unfavorable associations were observed between problematic social media use and all included psychosomatic complaints, as well as general life satisfaction. It is possible that these psychosomatic complaints are interrelated and may causally influence each other. For example, early adolescents who more often experience stomachaches or headaches might more often have difficulties falling asleep because of the pain, causing them to feel more tired during the day and have more concentration difficulties. In addition, sleep is also important for the regulation of emotions, as a deficit can cause more negative emotions [
46]. It is possible that the lower observed general life satisfaction is a consequence of the more frequent occurrence of physical and mental health complaints, but it is also possible that problematic social media use has a direct influence on life satisfaction, for example, due to social comparison. Future research should examine whether the association between problematic social media use and general life satisfaction is mediated by decreased health.
Besides the observed mental and physical health concerns of problematic social media use, these psychosomatic complaints might also have a negative influence on students’ academic careers. Students who experience more physical health problems and have lower well-being, as well as students who have more issues with concentration and have worse sleep quality, perform generally worse in school [
47,
48,
49,
50]. For example, a recent study from the Programme of International Student Assessment (PISA) shows that educational performance of Dutch secondary school students has decreased over the past decade, especially for reading skills [
51]. During this period, (problematic) social media use has strongly increased [
2].
Another aim of the current study was to examine whether this association can differ depending on the level of perceived social support. Although a few associations were moderated by social support, most outcomes showed no significant differences in associations between students who perceive social support as high or low. This shows how concerning the influence of social media use may be, since associations appear to be present for eighth-grade students, regardless of their social support. Nevertheless, a few associations were moderated by perceived social support from family, which appeared more important for influencing the associations than support from teachers, friends, and classmates. The association between problematic social media use and having a headache, having a bad mood or feeling irritated, and experiencing daytime fatigue weakened for students who perceived social support from family to be low. This was not in line with our hypothesis. Our results showed that students with low family support experience psychosomatic complaints more often in general. It is possible that early adolescents who have less supportive home environments already face concerns that may affect their well-being, while early adolescents with high family support have more room to be negatively affected by their problematic social media use. It is also possible that social media provides early adolescents with low family support a means to escape from their home environment and seek online support from peers and friends. Additionally, our findings showed that girls reported lower general life satisfaction and more often had psychosomatic complaints compared to boys. This was in line with the existing literature [
5]. However, associations between problematic social media use and these psychosomatic complaints were not stronger for girls, except for having trouble falling asleep.
The findings of our study indicate how concerning the popularity of social media among primary-school students is. Although more research is needed to examine the directionality, increased awareness among students and their parents is needed about the potential risks of problematic social media use for these students. Even though most popular social media platforms have age restrictions, i.e., prohibiting adolescents under 13 from creating accounts [
9], a study by CBS from 2019 revealed that nearly the entire population in the Netherlands aged 12 to 45 years old uses social media [
3]. Despite the existence of age restrictions, it is very easy to create an account if you are too young according to user guidelines. Because of the concerning associations with many physical and mental health complaints, supervision on the apps should be strengthened. Additionally, awareness of the potential risks of social media use needs to be raised among parents. Early adolescents should also be educated about the potential dangers of social media use, potentially through schools. For instance, the Dutch Healthy School program, which is widely adopted across schools in the Netherlands, also provides support to schools in stimulating responsible media use among primary-school students [
52]. Additionally, governments can play a crucial role by implementing laws aimed at reducing addictive features and mechanisms built into social media platforms, further protecting young users from harm. For example, since the school year 2024–2025, phones have been prohibited during classes in primary schools in the Netherlands. This might reduce (problematic) the social media use of students.
Limitations and Directions for Future Research
The current study contributed to the existing literature on the association between problematic social media use and health indicators, while also examining the potential influence of perceived social support and sex differences. Moreover, our study had good geographical coverage of schools in the Netherlands. A notable strength of the current study was the use of recent data from eighth-grade students, while including a broad range of outcomes. In particular, the association with physical health complaints has not been studied to a great extent to this date, as well as the moderation by individual and contextual factors. Therefore, this study provides timely insights into a rapidly evolving topic.
However, the current study also had several limitations that should be taken into account. One limitation was its cross-sectional design, which restricts the ability to draw conclusions about causality and the direction of relationships between variables. For example, it is possible that early adolescents who have more difficulties falling asleep have a higher problematic social media use, instead of the other way around. Future studies should explore directionality. Moreover, we had to obtain active, informed consent from parents or caregivers. Therefore, we only included data of around 37% of invited students, and doing so potentially resulted in selection bias. Our study sample had relatively fewer students with a migration background and parents with a low/medium educational attainment compared to the total study population within the participating schools, as well as all eighth-grade students in the Netherlands. For this comparison, we used preliminary data of eighth-grade students in 2021–2022, since these were the most recent available data. The difference between our study sample and the total study population might be a consequence of using solely Dutch recruitment materials and only providing a Dutch questionnaire, as well as an extensive IC-form. Therefore, we assume the generalizability to early adolescents from lower-SES families and early adolescents with a migration background to be limited. To increase the number of participants, future studies could use recruitment materials or questionnaires in different languages, or use different recruitment strategies, such as verbal, instead of written, recruitment. Additionally, students participating in our study also completed an end-of-primary-school test, with the data expected to be available in 2025. This presents an immediate opportunity to examine whether problematic social media use is indeed associated with lower educational performance. Based on the current findings, we hypothesize that problematic social media use is related to both lower well-being and worse educational performance.
