Ovarian hormones significantly influence dysregulated eating in females. However, most women do not develop appreciable disordered eating, suggesting that ovarian hormones may not affect all women equally. We examined whether individual differences in trait negative affect (NA) moderate ovarian hormone-dysregulated eating associations in 446 women who provided saliva samples for hormone measurements and ratings of NA and emotional eating daily for 45 consecutive days. Women were at greatest risk for emotional eating when they had high trait NA and experienced a hormonal milieu characterized by low estradiol or high progesterone. While effects were evident in all women, the combination of high trait NA and high progesterone was particularly risky for women with a history of clinically significant binge eating episodes. These findings provide initial evidence that affective and hormonal risk interact to promote emotional eating, and that effects may be amplified in women with clinically significant binge eating.
卵巢激素对女性饮食失调有显著影响。然而，大多数女性并未出现明显的饮食紊乱，这表明卵巢激素对所有女性的影响可能并不相同。我们对446名女性进行了研究，这些女性连续45天提供唾液样本用于激素测量，并对特质负性情绪（NA）和情绪化饮食进行每日评分，以检验特质负性情绪的个体差异是否会调节卵巢激素与饮食失调之间的关联。当女性具有高特质NA且处于低雌二醇或高孕酮的激素环境中时，她们出现情绪化饮食的风险最高。虽然在所有女性中都有明显影响，但高特质NA和高孕酮的组合对有临床显著暴饮暴食发作史的女性尤其危险。这些发现提供了初步证据，表明情感和激素风险相互作用会促进情绪化饮食，并且在有临床显著暴饮暴食的女性中这种影响可能会放大。
