The highest intensity of back pain occurs between 7:00 am and noon, the research also found.
Manuela Ferreira from University of Sydney in New South Wales, Australia said: “Understanding which risk factors contribute to back pain and controlling exposure to these risks is an important first step in prevention. Our study is the first to examine brief exposure to a range of modifiable triggers for an acute episode of low back pain.”
During the course of life, about 10 percent of population worldwide goes through various forms of back pain, a leading cause of disability, according to World Health Organisation (WHO) Global Burden of Disease.
The study was published in the journal Arthritis Care & Research.
Researchers examined about 1,000 participants from 300 primary care clinics in Sydney, Australia who were suffering acute lower back pain episodes between October 2011 and November 2012. Participants were asked to account for 12 physical or psycho-social factors that occurred in the 96 hours before the back pain.
Several types of triggers were responsible for an increased risk of new back pain episode, from 2.7 for moderate to vigorous physical activity to 25 for distractions that occurred during an activity.
Age seemed to moderate the effect of exposure to heavy loads, researchers found.
“Understanding which modifiable risk factors lead to low back pain is an important step toward controlling a condition that affects so many worldwide,” Ferreira concluded.
