Insomnia was negatively associated with change in eating self-efficacy (r = −0.35, p = 0.018) and increased thigh circumference (r = −0.35, p = 0.017), while change in waist circumference was positively associated with increased thigh circumference (r = 0.30, p = 0.048) and change in ApoB/ApoA ratio (r = 0.35, p = 0.020) (Table 4). This evidence concerns the gene APOA1 and insomnia.
