Waist and neck enlargement after quadriplegia

Changes in waist and neck size in quadriplegic patients after paralysis, noted clinically, were assessed systematically. Twenty quadriplegic men, aged 60 +/- 13 years (mean +/- 1 SD) and 20 neurologically intact men, aged 63 +/- 17 years, selected by absence of weight gain, were questioned about changes in their waist and shirt collar sizes since the onset of paralysis (20 +/- 13 years) or during the previous 20 years for control subjects. Waist size expanded 7.0 +/- 0.3 inches for quadriplegic and 1.7 +/- 1.7 inches for control subjects (p < 0.001). Changes in neck size of 0.7 +/- 1.1 inches for quadriplegic and 0 +/- 0.7 inches for control subjects were found (p < 0.02). We conclude that quadriplegia is often followed by increased waist and neck size. These changes may relate to the impaired breathing mechanisms in quadriplegia.
