Study Finds Reducing Daily Sitting Time May Prevent Back Pain Worsening

The figure presents the change in back pain intensity on a scale from 0 to 10. The blue bars represent individuals in the intervention group that reduced sitting and the red bars represent the control participants who did not change their sitting habits. Most of the participants in the intervention group decreased their back pain whereas the back pain in the control participants tended to increase.

New research reveals that cutting down on sedentary behavior could be key to maintaining back health, especially for overweight and obese adults.

Summary: A six-month study from the University of Turku shows that reducing daily sitting time by an average of 40 minutes can prevent back pain from worsening in overweight and obese adults.

Estimated reading time: 5 minutes

A recent study conducted by researchers at the University of Turku and UKK Institute in Finland has shed new light on the relationship between sedentary behavior and back pain. The research, published in BMJ Open, suggests that reducing daily sitting time could be an effective strategy for preventing the worsening of back pain in overweight and obese adults.

The study’s findings come at a crucial time when many people are spending increasing amounts of time seated due to work and lifestyle factors. This research offers a practical approach to potentially mitigate the risk of back pain, a condition that affects millions worldwide and can significantly impact quality of life.

The Link Between Sitting and Back Pain

The study involved 64 adults with overweight or obesity and metabolic syndrome, who were randomly divided into intervention and control groups. The intervention group was tasked with reducing their sedentary behavior by one hour per day over a six-month period, while the control group maintained their usual habits.

Doctoral Researcher and Physiotherapist Jooa Norha from the University of Turku explains the participant profile: “Our participants were quite normal middle-aged adults, who sat a great deal, exercised little, and had gained some extra weight. These factors not only increase the risk for cardiovascular disease but also for back pain.”

Key findings from the study include:

  1. Participants in the intervention group successfully reduced their sitting time by an average of 40 minutes per day.
  2. Back pain intensity remained unchanged in the intervention group but increased significantly in the control group.
  3. Pain-related disability increased in both groups, but there was no statistically significant difference between the groups.

These results suggest that while reducing sitting time may not necessarily improve existing back pain, it could play a crucial role in preventing its worsening over time.

Investigating the Mechanisms Behind Back Pain

The research team employed advanced imaging techniques to explore potential mechanisms behind the prevention of back pain. They used magnetic resonance imaging (MRI) and positron emission tomography (PET) to examine changes in back muscle composition and metabolism.

Previous research has indicated that individuals with back pain often have excessive fat deposits within their back muscles and impaired glucose metabolism. However, this study found no direct link between changes in back pain and alterations in muscle composition or metabolism.

Norha elaborates on this finding: “However, we did not observe that the changes in back pain were related to changes in the fattiness or glucose metabolism of the back muscles.”

This suggests that the benefits of reducing sitting time on back pain may be independent of these muscular changes, pointing to the need for further research to uncover the exact mechanisms at play.

Practical Implications for Back Health

For those concerned about their back health or who spend significant time sitting, the study offers some practical advice. Norha suggests, “If you have a tendency for back pain or excessive sitting and are concerned for your back health, you can try to figure out ways for reducing sitting at work or during leisure time.”

However, the researchers emphasize that simply standing is not enough. “It is important to note that physical activity, such as walking or more brisk exercise, is better than simply standing up,” Norha points out.

The study also highlights the importance of varying postures throughout the day. As Norha notes, “switching between postures is more important than only looking for the perfect posture.”

Looking Ahead: Future Research and Applications

While this study provides valuable insights into the relationship between sedentary behavior and back pain, it also opens up new avenues for future research. Some questions that remain to be addressed include:

  1. What are the long-term effects of reduced sitting time on back pain?
  2. Are there specific types of movement or activities that are most beneficial for back health?
  3. How do these findings apply to different populations, such as those with chronic back pain or individuals of normal weight?

As research in this area continues to evolve, it may lead to new guidelines for workplace ergonomics, lifestyle interventions for back pain prevention, and potentially even treatment protocols for those already experiencing back issues.

This study underscores the importance of addressing sedentary behavior as a public health concern, not just for cardiovascular health but also for musculoskeletal well-being. By making small changes in our daily routines to reduce sitting time, we may be able to take a significant step towards better back health and overall quality of life.
