24-Hour Movement Behaviors and Mental Health in University Students: Descriptive Data and Cluster Analysis of European Data
This study of 2,340 European university students reveals that the majority fail to meet all 24-hour movement guidelines simultaneously, a deficit strongly associated with poorer mental health outcomes, particularly among female students and those exhibiting unfavorable movement behavior profiles.

The human day is a single, continuous resource, a finite twenty-four hours that must be divided among movement, rest, and stillness. For decades, scientists have studied these activities in isolation, asking how much exercise is enough, how many hours of sleep are required, or how much time spent sitting is too much. However, a newer perspective suggests that these behaviors are not separate items on a checklist but parts of a single, interconnected system. This framework, known as the twenty-four-hour movement behavior approach, recognizes that time spent sitting is time not spent moving, and time spent sleeping is time not spent awake. When researchers look at these habits together, they can see how the balance of a whole day influences a person's mind, not just their body. This is particularly urgent for university students, a group navigating a critical life stage where psychological stress is high and lifelong habits are being formed.
A recent study involving more than two thousand university students across five European nations sought to understand this balance and its impact on mental well-being. The researchers gathered data from students in France, Spain, Romania, and Italy, asking them to report their weekly physical activity, the time they spent sitting, their leisure screen time, and the quality and duration of their sleep. They also measured mental health using standard tools that assess anxiety, depression, stress, and a sense of inner vitality. The goal was not just to count how many students met specific health guidelines, but to see if distinct patterns of behavior emerged within the student population and whether those patterns predicted how students felt emotionally.
The results revealed a complex picture of student life. While a vast majority of the students reported getting enough moderate-to-vigorous physical activity each week, far fewer met the guidelines for other parts of their day. Only about two-thirds of the students adhered to recommendations for sleep duration and leisure screen time, and less than half met the guidelines for limiting sedentary behavior. When the researchers looked at the students who managed to meet all four guidelines simultaneously, they found that only about one in four students achieved this balance. This suggests that being physically active does not automatically mean a student is living a balanced lifestyle; many are active yet also spend excessive hours sitting or staring at screens.
The study also uncovered a stark divide in the mental health of these students. Nearly half of the participants reported significant symptoms of anxiety, while more than a third experienced depression or high levels of stress. These numbers were not evenly distributed. Female students consistently reported higher levels of psychological distress and lower levels of well-being compared to their male counterparts. They were more likely to report poor sleep quality, higher sedentary time, and greater frustration with their basic psychological needs, such as feeling a sense of autonomy or competence in their lives.
To make sense of these varied behaviors, the researchers used a statistical method to group students based on their daily habits rather than their individual scores. This analysis split the population into two distinct profiles. The first group, representing slightly more than half of the students, displayed a favorable pattern: they were active, sat less, and slept better. The second group showed an unfavorable pattern, characterized by lower activity, more sitting, and poorer sleep. The difference between these two groups was profound. Students in the unfavorable group were significantly more likely to report high levels of anxiety, depression, and stress, and they were less likely to feel a sense of vitality or satisfaction in their lives.
The study confirmed that belonging to this unfavorable behavioral profile was a strong predictor of poor mental health, independent of gender. However, gender remained a powerful factor on its own. Female students were overrepresented in the unfavorable group and, regardless of which group they belonged to, they faced a higher risk of psychological distress than male students. The research suggests that the combination of an unhealthy daily rhythm and female gender creates a particularly vulnerable situation for mental health.
The authors emphasize that their findings are based on self-reported data, meaning they reflect the students' own perceptions of their habits rather than objective measurements from devices. They also note that because the study was conducted at a single point in time, it cannot prove that poor movement habits cause mental health issues, only that they are closely linked. Despite these limitations, the study provides a clear warning: the mental health of university students is under significant strain, and this strain is deeply connected to how they spend their twenty-four hours. The researchers conclude that interventions aimed at improving student well-being must look beyond simple advice to exercise. Instead, they should focus on integrated strategies that help students balance their entire day, reducing sedentary time and improving sleep, with a special attention to supporting female students who appear to be at the greatest risk.
