Acute cold exposure decreases plasma leptin in women

We investigated whether cold exposure affects circulating leptin in humans. Five women (age, 32 ± 4 years ; body mass index, 23.1 ± 1.7 kg/m2 ) participated in two separate trials. Subjects sat at room temperature ([RT] 24.8° ± 0.3°C) or in the cold (6.3° ± 0.5°C) for 90 minutes. During RT exposure,...

Zusammenfassung:	We investigated whether cold exposure affects circulating leptin in humans. Five women (age, 32 ± 4 years ; body mass index, 23.1 ± 1.7 kg/m2 ) participated in two separate trials. Subjects sat at room temperature ([RT] 24.8° ± 0.3°C) or in the cold (6.3° ± 0.5°C) for 90 minutes. During RT exposure, plasma leptin and norepinephrine were unchanged over time. Cold exposure significantly decreased plasma leptin by 14%, 17%, and 22% at 30, 60, and 90 minutes, respectively (temperature x time interaction, P
