Clinical Trial Summary

Since 1980, the global prevalence of obesity, commonly defined as a body mass index (BMI) of 30 or higher, has doubled. Importantly, high levels of central adiposity (i.e., abdominal fat) is associated with numerous PNI-related sequelae, including increased levels of psychological distress, cognitive deficits, ANS dysfunction, and immune marker abnormalities. To our knowledge, rigorous investigation of chiropractic's impact on psychoneuroimmunological (PNI)-related outcomes in people with high central adiposity is lacking. Based on limited evidence to date, it is plausible that clinically important PNI-related dysfunctions (e.g., heightened stress levels, executive function impairments, dysautonomia, immune dysregulation) common in this population could be ameliorated via chiropractic care.

Description:

Up to twenty (20) obese individuals (18-65 yrs of age) will be recruited. For our trial, obesity will be indexed as a BMI ≥30 and an elevated waist circumference (i.e., >35 inches for women, >40 inches for men). Subjects will be asked to do the following… - Restrict certain behaviors prior to their lab visits which include 1) 3 hours prior abstain from caffeine, brushing your teeth, alcohol-based mouthwash, nicotine, food, & drinking large amounts of liquid very quickly (e.g., chugging a 16 oz bottle of water; sipping water is ok) and 2) 24 hours prior abstain from strenuous exercise, alcohol, & over the counter drugs (e.g., antihistamines, Tylenol, etc.) - Have their height, weight, and waist circumference measured. - Drool into a tube for subsequent testing of immune markers (i.e., salivary IgA) - Have electrodes placed on/around their chest & back to measure respiration, ECG, and impedance cardiography (ICG) - Perform a postural challenge whereby they lay supine (8 min), stand quickly (3 min), and return quickly to the supine position (3 min). - Have their cognitive function assessed while walking on a treadmill (dual task). - Answer questions about their mental, physical, and emotional health. - Receive 6-weeks of chiropractic adjustments from community-based clinicians. Assessments will take place at baseline, after 2 weeks of chiropractic, and after 6 weeks of chiropractic.
