Objective: To develop a model to predict the perceived severity of hot flashes (HF) and night sweats (NS)
in symptomatic middle-aged women.
Methods: This was a cross-sectional study of a community-based sample of 243 women with vasomotor
symptoms. Menopausal status was ascertained using the ‘Stages of Reproductive Aging Workshop’ criteria.
Women’s ‘perceived control’ over their symptoms was measured by a validated Portuguese version of
the Perceived Control over Hot Flushes Index. Structural equation modelling was employed to construct
a causal model of self-reported severity of both HF and NS, using a set of 20 variables: age, marital status,
parity, professional status, educational level, family annual income, recent diseases and psychological
problems, medical help-seeking behaviour to manage menopausal symptoms, use of hormone therapy
and herbal/soy products, menopause status, intake of alcohol, coffee and hot beverages, smoking, physical
exercise, body mass index and perceived control.
Results: Significant predictors of perceived severity were the use of hormone therapy for both HF
(B = −.245; p = .022) and NS (B = −.298; p = .008), coffee intake for both HF (B =
−.234; p = .039) and NS
(B =
−.258; p = .029) and perceived control for both HF (B =
−1.0; p < .001) and NS (B =
−1.0; p < .001). The
variables explained respectively 67% and 72% of the variability in the perceived severity of HF and NS.
Women with high perceived control had a significantly lower frequency (t(235) = 2.022; p = .044) and
intensity of HF (t(217) = 3.582; p < .001); similarly, participants with high perceived control presented a
lower frequency (t(235) = 3.267; p < .001) and intensity (t(210) = 3.376; p < .001) of NS.
Conclusion: Perceived control was the strongest predictor of the self-reported severity of both HF and NS.
Other causal predictors were hormone therapy and caffeine intake. All three were associated with less
severe vasomotor symptoms.
