Weight change after spinal cord injury

Area of Science:

• Neurology
• Rehabilitation Medicine
• Public Health

Background:

• Spinal cord injury (SCI) can significantly impact an individual's metabolism and physical activity levels.
• Understanding weight change patterns post-SCI is crucial for long-term health management and complication prevention.

Purpose of the Study:

• To investigate weight change trends in the first year following spinal cord injury.
• To identify demographic and injury-related factors associated with weight fluctuations after SCI.

Main Methods:

• A cohort study involving 1,094 individuals with SCI was conducted using data from the Spinal Cord Injury Model Systems (SCIMS) database.
• Body Mass Index (BMI) was assessed at rehabilitation discharge and one year post-injury to track changes.

Main Results:

• Mean BMI decreased by 0.5 kg/m² in the first year post-SCI. Significant weight loss occurred in individuals who were overweight or obese at baseline.
• Weight gain was observed in underweight or normal-weight individuals, with higher increases noted in specific demographic groups (Hispanic origin, certain marital statuses, age 31-45, lower education levels) and injury types (motor incomplete).
• Factors influencing weight change included sex, education, neurological level, vertebral injury presence, and marital status.

Conclusions:

• Weight changes after SCI are common and vary significantly based on initial BMI and demographic factors.
• Interventions for weight management should be considered post-SCI to address potential unhealthful weight fluctuations.
• Targeted strategies are necessary for at-risk populations to mitigate adverse health outcomes associated with weight changes.
