We previously reported that female smokers evidence greater subjective craving and stress/emotional reactivity to personalized stress cues than males. The present study employed the same dataset to assess whether females in the follicular versus luteal phase of the menstrual cycle accounted for the gender differences.
Two objective criteria, onset of menses and luteinizing hormone surge (evaluated via home testing kits), were used to determine whether female smokers were in either the follicular (n = 22) or the luteal (n = 15) phase of their menstrual cycle, respectively. The females and a sample of male smokers (n = 53) were then administered a laboratory-based cue reactivity paradigm that involved assessment of craving, stress, and emotional reactivity in response to counterbalanced presentations of both a personalized stress script and neutral/relaxed script.
While there were no significant differences between females in the follicular versus luteal phase on any outcome measure, females in the luteal menstrual phase reported greater craving than males whereas females in the follicular phase reported greater stress and arousal than males and perceived the stress cues as more emotionally aversive than males.
This preliminary investigation suggests that gender differences in craving versus affective responding to stress cues may, in part, be explained variation by menstrual cycle phase. Study limitations and implications of the findings for future research and treatment are briefly discussed.
我们之前报道过,女性吸烟者相较于男性,对个性化压力线索表现出更强烈的主观渴望以及压力/情绪反应。本研究采用相同数据集,以评估处于月经周期卵泡期与黄体期的女性是否能够解释这种性别差异。
使用月经初潮和促黄体生成素激增这两个客观标准(通过家用检测试剂盒评估),分别确定女性吸烟者处于月经周期的卵泡期(n = 22)还是黄体期(n = 15)。然后,对这些女性以及一组男性吸烟者样本(n = 53)进行基于实验室的线索反应范式测试,该测试涉及在平衡呈现个性化压力脚本和中性/放松脚本的情况下,评估渴望、压力和情绪反应。
虽然卵泡期与黄体期的女性在任何结果指标上均无显著差异,但处于月经黄体期的女性比男性表现出更强烈的渴望,而处于卵泡期的女性比男性表现出更大的压力和唤醒水平,并且认为压力线索比男性更具情绪厌恶感。
这项初步调查表明,在对压力线索的渴望与情感反应方面的性别差异,可能部分可由月经周期阶段的变化来解释。本文简要讨论了研究局限性以及这些发现对未来研究和治疗的意义。
