Researchers at a university in Cameroon studied 1,539 college students to understand why some develop chronic lower back pain. They found that about 1 in 15 students suffer from this problem. The study discovered two main risk factors: being overweight or obese, and having parents who also experienced back pain. Most students with chronic back pain had only mild disability, meaning it didn’t completely stop them from doing daily activities. The findings suggest that maintaining a healthy weight through exercise and good eating habits might help prevent this common problem in young people.
The Quick Take
- What they studied: Why some college students develop chronic lower back pain and what factors make it more likely to happen
- Who participated: 1,539 college students from the University of Dschang in Cameroon, with an average age of 20 years old. About 40% were male and 60% were female.
- Key finding: About 6.2% of students (roughly 1 in 15) reported chronic lower back pain. Students who were overweight or obese were 1.8 times more likely to have back pain, and students whose parents had back pain were 2.6 times more likely to experience it themselves.
- What it means for you: If you’re a college student, maintaining a healthy weight through exercise and eating well may help prevent chronic back pain. If your parents have back pain, you might want to be extra careful about your posture and fitness. However, this study was done at one university in Africa, so results may differ in other places.
The Research Details
This research had two parts working together. First, researchers surveyed 1,539 students across different departments and year levels to count how many had chronic lower back pain. They used a simple questionnaire to ask students about their back pain history. Second, they compared students who had chronic back pain (called ‘cases’) with students who didn’t have back pain (called ‘controls’). They matched these two groups by age and sex to make fair comparisons. For every student with back pain, they included two students without back pain. This design helps researchers figure out what factors actually cause the problem by comparing the two groups.
The case-control design is useful because it lets researchers study a health problem that doesn’t happen to everyone. By comparing people who have the problem with similar people who don’t, scientists can identify what’s different between the groups. This approach is faster and cheaper than following people over many years. The stratified sampling method (choosing students from different departments and year levels) helps make sure the results represent the whole student population, not just one group.
The study used a pre-tested questionnaire, which means they tested their questions before using them to make sure they worked well. The researchers carefully matched the two groups by age and sex to reduce confusion from other factors. They also adjusted their results for confounding factors (other things that might affect the outcome). The study was published in a peer-reviewed journal, meaning other experts reviewed it before publication. However, the study was done at only one university in one country, so the results might not apply everywhere. The relatively small number of students with back pain (about 95 students) means some findings might change if more students were studied.
What the Results Show
Out of 1,539 students surveyed, 95 students (6.2%) reported chronic lower back pain. This means about 1 in every 15 college students at this university experiences this problem. The good news is that most students with chronic back pain (64.2%) had only mild disability, meaning they could still do most of their daily activities. When researchers compared students with back pain to those without, they found two strong connections: Students who were overweight or obese were 1.82 times more likely to have chronic back pain compared to students at a healthy weight. This relationship was statistically significant, meaning it’s unlikely to be due to chance. Students whose parents had a history of back pain were 2.6 times more likely to develop chronic back pain themselves. This is an even stronger connection than weight, suggesting that genetics or family habits may play an important role.
The study found that most students with chronic back pain experienced only mild symptoms based on the Roland-Morris disability scale, which measures how much pain affects daily life. This suggests that while back pain is common among college students, severe disability is less common. The sex ratio of the study (more female than male students) reflects the actual student population at the university, which helps make the results more representative.
This study adds to growing evidence that chronic back pain is becoming more common in young people worldwide, not just in older adults. Previous research has shown that weight and family history are risk factors for back pain in general populations, and this study confirms these findings specifically in college students in Africa. The 6.2% prevalence rate is consistent with other studies of back pain in young adult populations, though rates vary depending on how back pain is defined and measured.
This study was conducted at only one university in Cameroon, so the results might not apply to college students in other countries or regions with different lifestyles and healthcare systems. The study is cross-sectional, meaning it captured a snapshot in time rather than following students over months or years, so we can’t be completely sure about cause and effect. The study relied on students reporting their own pain through interviews, which might not be perfectly accurate. Some students might have forgotten about past pain or not reported it accurately. The study didn’t measure other potential factors like stress, sleep quality, or how much time students spend sitting, which could also affect back pain. Additionally, the relatively small number of students with back pain means some findings could change if a larger group was studied.
The Bottom Line
College students should aim to maintain a healthy weight through regular physical exercise and a balanced diet. This is supported by moderate evidence from this study. Students with a family history of back pain should pay extra attention to posture, exercise, and weight management. These recommendations are practical and align with general health advice. However, if you develop chronic back pain, you should see a healthcare provider for proper evaluation and treatment, as this study only identifies risk factors, not treatments.
College students, especially those who are overweight or have parents with back pain, should pay attention to these findings. Young adults in general should be aware that back pain isn’t just an older person’s problem. Parents and educators might use this information to encourage healthy habits in young people. Healthcare providers working with college students can use these findings to identify at-risk students. This study is less relevant to people who are already experiencing severe back pain, as they need medical treatment rather than prevention strategies.
Maintaining a healthy weight through exercise and diet is a long-term commitment, not a quick fix. You might notice improved energy and fitness within a few weeks of starting regular exercise, but protection against back pain develops over months and years of consistent healthy habits. If you already have back pain, improvement depends on the cause and treatment, which could take weeks to months.
Want to Apply This Research?
- Track your weekly exercise minutes (aim for 150 minutes of moderate activity) and monitor your weight monthly. If you have back pain, rate your pain level on a scale of 0-10 daily to see if exercise and weight changes help.
- Set a goal to do 30 minutes of moderate exercise (like brisk walking, swimming, or cycling) at least 5 days per week. Use the app to log your workouts and get reminders. Also track your meals to maintain a healthy diet that supports weight management.
- Use the app to create a 3-month tracking plan: record exercise frequency and duration, monitor weight weekly, and if you have back pain, track pain levels and any activities that make it better or worse. Review your progress monthly to see if consistent exercise and healthy eating are helping prevent or reduce back pain.
This research identifies risk factors associated with chronic back pain in college students but does not provide medical treatment advice. If you experience chronic back pain, consult with a healthcare provider for proper diagnosis and treatment. This study was conducted at one university in Cameroon and may not apply to all populations. The findings suggest associations but do not prove cause and effect. Always speak with a doctor before starting a new exercise program, especially if you currently have back pain or other health conditions.
