Figure 1.

Prevalence (percentage) of women reporting sleep difficulty ≥3 times per week in the past 2 weeks across menopausal transition status (N = 3045). Percentages reporting each sleep difficulty (Y-axis) are plotted as “trouble falling asleep” (left figure), “wake up several times” (center figure), and “wake up early” (right figure).

Note: Percentages were computed as average rates across menopausal status. Women could contribute to more than one menopausal transition state, and within each menopausal transition state a woman could contribute more than one observation. For women with more than one observation within a specific menopausal transition state, the within-woman average sleep score was computed before dichotomizing. Also, “surgery” (i.e., surgically menopausal status) could follow any menopausal status. HT users were excluded from this figure.
