Abstract

At month 6, however, mean (±SD) min of sleep increased significantly more in participants who lost ≥5% vs. <5% (21.6 ± 7.2 vs. 1.2 ± 6.0 min, <italic>P</italic> = 0.0031). PSQI total scores similarly improved (declined) more in those who lost ≥5% vs. <5% (−1.2 ± 0.2 vs. −0.4 ± 0.2, <italic>P</italic> < 0.001), as did PHQ‐8 scores (−2.5 ± 0.4 vs. −0.1 ± 0.3, <italic>P</italic> < 0.0001).
