Prevalence of Back Pain and Its Association With Smartphone Usage Patterns Among Young Healthcare Professionals in Karachi, Pakistan: A Cross-Sectional Study
This cross-sectional study of 168 young healthcare professionals in Karachi found that daily smartphone use of four hours or more is significantly associated with a higher prevalence of back pain compared to shorter usage durations.

Back pain is a universal human experience, a common ache that can disrupt daily life, limit movement, and make simple tasks feel heavy. For healthcare workers, this discomfort is often compounded by the physical demands of their jobs, such as long shifts, lifting patients, and standing for hours. In recent years, a new factor has entered the picture: the smartphone. These devices are now essential tools for doctors and nurses, used for checking medical records, communicating with colleagues, and studying. However, holding a phone for hours often means bending the neck and hunching the shoulders, a posture that strains the spine. While it is well known that poor posture can hurt the back, scientists have not yet fully understood how much time spent on a phone actually contributes to back pain, especially among young medical professionals who are just starting their careers.
A team of researchers in Karachi, Pakistan, set out to explore this connection. They focused on young healthcare workers between the ages of twenty and thirty-five, a group that relies heavily on smartphones for both their training and their daily work. The study took place over six months at two major hospitals in the city. The researchers asked 168 participants to fill out a questionnaire about their habits. They wanted to know how many hours each person spent on their phone every day, how they held the device, and whether they had experienced any pain in their upper or lower back during the previous year. The goal was not to prove that phones cause pain, but to see if there was a clear link between the amount of time spent on the device and the presence of back pain.
The results revealed a striking pattern. Among the young professionals surveyed, nearly three out of four reported having experienced back pain in the last twelve months. When the researchers looked closer at the habits of these individuals, a difference emerged based on screen time. Those who reported using their smartphones for four hours or more each day were significantly more likely to report back pain than those who used their phones for less than four hours. Specifically, about eighty percent of the heavy users reported back pain, compared to fifty-five percent of the lighter users. This difference remained consistent even after the researchers accounted for other factors like age and gender, suggesting that the duration of phone use is a notable factor in this group's health.
The study also painted a picture of how these young professionals interact with their devices. Most of them admitted to using their phones for long stretches, often while lying in bed or staying in the same position for extended periods. Many reported that they frequently used their phones longer than they originally intended. When it came to taking breaks or changing their posture, more than half said they rarely or never stopped to stretch or adjust their position during these long sessions. This lack of movement, combined with the static, hunched posture required to look at a small screen, creates a physical environment that is likely to strain the muscles and spine over time.
Despite these strong associations, the researchers were careful to explain what their findings do and do not mean. Because the study asked people to recall their past habits and pain at a single point in time, it cannot prove that the phone use caused the pain. It is possible that people who already have back pain might use their phones differently, or that other factors, such as the physical stress of their medical jobs, are the true cause. The study did not find a simple, step-by-step increase in pain as screen time went up; rather, it identified a threshold where the risk appeared higher. The researchers also noted that the participants were from just two hospitals, so the results might not apply to every healthcare worker in the country.
Ultimately, this research highlights a growing concern for the physical well-being of the next generation of medical staff. It suggests that the way these professionals use their smartphones is linked to a higher likelihood of back pain, adding a new layer to the existing challenges of their demanding careers. While the study does not offer a definitive cure or a strict rule for how many hours are "safe," it points to the need for greater awareness. For young doctors and nurses, being mindful of how long they spend on their devices and how they hold them could be a simple step toward protecting their backs. Future research will need to look at these habits over a longer period to understand the true cause-and-effect relationship, but for now, the connection between the screen and the spine is clear enough to warrant attention.
