Hot flushes and night sweats (HF/NS) can be measured objectively using sternal skin conductance (SSC) monitoring, but objective and subjective measures of HF/NS have only moderate concordance. We aim to investigate this discordance and factors affecting perceptions of HF/NS in a UK sample.
Twenty-seven menopausal women completed questionnaires assessing beliefs about HF/NS, mood, stress, somatic amplification and subjective (frequency and problem-rating) and objective (24-h SSC) HF/NS measures.
On average, 48 HF/NS were reported per week; 47% of objectively recorded HF/NS were accompanied by a subjective response and 56% of subjectively recorded HF/NS were accompanied by an objective recording. Concordant HF/NS were more likely to be moderate or severe, while over-reported (false-positive) HF/NS tended to be mild or moderate; night sweats were more likely to be under-reported. Anxiety, somatic amplification and body mass index were associated with negative beliefs about HF/NS and, in turn, negative beliefs were associated with more problematic HF/NS.
Different patterns of discordance were evident for hot flushes and night sweats. Both subjective and objective measures should be included in the evaluation of treatments for HF/NS. The possible role of beliefs in mediating the influence of anxiety, somatic amplification and body mass index upon HF/NS experience warrants further investigation.
可以使用胸骨皮肤电导（SSC）监测来客观地测量热潮和盗汗（HF/NS），但 HF/NS 的客观和主观测量只有中等一致性。我们旨在调查这种不和谐以及影响英国样本中 HF/NS 感知的因素。
27 名绝经后妇女完成了问卷，评估了对 HF/NS 的信念、情绪、压力、躯体放大以及主观（频率和问题评分）和客观（24 小时 SSC）HF/NS 测量。
平均每周报告 48 次 HF/NS；47%的客观记录的 HF/NS 伴有主观反应，56%的主观记录的 HF/NS 伴有客观记录。一致的 HF/NS 更可能是中度或重度，而过度报告（假阳性）的 HF/NS 往往是轻度或中度；盗汗更有可能被低估。焦虑、躯体放大和体重指数与对 HF/NS 的负面信念相关，而负面信念又与更具问题性的 HF/NS 相关。
热潮和盗汗的不和谐模式不同。在评估 HF/NS 的治疗时，应同时包括主观和客观测量。信念在调节焦虑、躯体放大和体重指数对 HF/NS 体验的影响方面可能发挥作用，值得进一步研究。
