Figure 1: Scattered plots of leptin (a) and adiponectin (b) as a function of waist girth. There was a trend for a linear association of leptin to waist girth ( ; ). Subjects with waist girths below 90 cm consistently had the lowest leptin levels. More interindividual variations were noted in the leptin levels of subjects in waist girth in the range of 90 to 101 cm. In contrast to leptin, adiponectin was not linearly associated with waist girth (b). There was a striking interindividual variation in adiponectin levels at each waist girth subcategory, that is, nonobese, overweight, and obese.
