Associations between obesity, physical and mental function, and low back pain intensity and disability: A 14-year...

Area of Science:

• Public Health
• Epidemiology
• Clinical Research

Background:

• Back pain is a significant public health issue with complex contributing factors.
• Overweight/obesity and impaired physical/mental function are prevalent conditions that may influence back pain.
• Understanding the interplay of these factors is crucial for effective prevention and management strategies.

Purpose of the Study:

• To investigate the associations between overweight/obesity, physical function, and mental function with back pain intensity and disability.
• To identify individuals at higher risk for developing severe back pain over time.
• To inform public health interventions for back pain reduction.

Main Methods:

• A 14-year population-based cohort study using data from the Australian Diabetes, Obesity and Lifestyle Study.
• Assessment of overweight/obesity using Body Mass Index (BMI).
• Evaluation of physical and mental function using the SF-36 Survey.
• Measurement of back pain intensity and disability using the Chronic Pain Grade Questionnaire.

Main Results:

• Overweight/obesity alone was associated with higher odds of high-intensity back pain and disability.
• Individuals with overweight/obesity and impaired physical function had substantially higher odds (9.5x pain, 7.8x disability) of severe back pain.
• Overweight/obesity combined with impaired mental function also significantly increased the odds of high-intensity pain (4.2x) and disability (2.9x).

Conclusions:

• Impaired physical and mental functions are critical indicators for identifying individuals with overweight/obesity at risk for high-intensity back pain and disability.
• Longitudinal examination of weight status and physical/mental health is warranted.
• Targeting weight management and functional health concurrently may mitigate the community burden of back pain.
