Sleep Characteristics and Carotid Atherosclerosis Among Midlife Women.

ABSTRACT:

Introduction

Midlife, which encompasses the menopause transition in women, can be a time of disrupted sleep and accelerated atherosclerosis accumulation. Short or poor sleep quality has been associated with cardiovascular disease (CVD) risk; few studies have investigated relations among midlife women. We tested whether shorter actigraphy sleep time or poorer subjective sleep quality was associated with carotid atherosclerosis among midlife women.

Aims and methods

Two hundred fifty-six peri- and postmenopausal women aged 40-60 years completed 3 days of wrist actigraphy, hot flash monitoring, questionnaires (Pittsburgh Sleep Quality Index [PSQI], Berlin), a blood draw, and carotid ultrasound [intima media thickness (IMT), plaque]. Associations of objective (actigraphy) and subjective (PSQI) sleep with IMT/plaque were tested in regression models (covariates: age, race, education, body mass index, blood pressure, lipids, insulin resistance, medications, snoring, depressive symptoms, sleep hot flashes, and estradiol).

Results

Shorter objective sleep time was associated with higher odds of carotid plaque (for each hour shorter sleep, plaque score ? 2, odds ratio (OR) [95% confidence interval, CI] = 1.58 [1.11-2.27], p = .01; plaque score = 1, OR [95% CI] = 0.95 [0.68-1.32], p = .75, vs. no plaque, multivariable). Poorer subjective sleep quality was associated with higher mean IMT [?, b (standard error, SE) = 0.004 (0.002), p = .03], maximal IMT [b (SE) = 0.009 (0.003), p = .005], and plaque [plaque score ? 2, OR (95% CI) = 1.23 (1.09-1.40), p = .001; score = 1, OR (95% CI) = 1.06 (0.93-1.21), p = .37, vs. no plaque] in multivariable models. Findings persisted additionally adjusting for sleep hot flashes and estradiol.

Conclusions

Shorter actigraphy-assessed sleep time and poorer subjective sleep quality were associated with increased carotid atherosclerosis among midlife women. Associations persisted adjusting for CVD risk factors, hot flashes, and estradiol.

Project description:BackgroundThe menopause has adverse effects on cardiometabolic profiles that are linked to an increased risk of atherosclerosis in women. A healthy diet during the menopausal transition may counteract the menopause-induced atherosclerotic risk.ObjectiveThis prospective cohort study aimed to examine the associations between empirically derived dietary patterns and subclinical carotid atherosclerosis in midlife women.MethodsA total of 1246 midlife women (average age at baseline: 46.3 y) from the Study of Women's Health Across the Nation who completed dietary assessments and had a carotid ultrasound scan were included. Dietary data were collected at 3 time points, during 1996-1997, 2001-2003, and 2005-2007. Measures of carotid atherosclerosis included common carotid artery intima-media thickness (CCA-IMT), adventitial diameter (AD), and carotid plaque index collected during 2009-2013. Three statistical methods, including principal component analysis (PCA), reduced rank regression (RRR), and partial least squares regression (PLS), were used to identify dietary patterns.ResultsA Western dietary pattern was identified from each method and a Prudent dietary pattern from PCA. High adherence to the Western pattern was associated with higher CCA-IMT. Women in the fourth quartile of the Western pattern identified by PCA, RRR, and PLS had 0.042 mm (95% CI: 0.011, 0.073), 0.033 mm (95% CI: 0.0086, 0.057), and 0.049 mm (95% CI: 0.025, 0.074), respectively, larger CCA-IMT than women in the first quartile; these differences correspond to 30%, 24%, and 35% of the sample SD, respectively. The Prudent pattern was not significantly associated with CCA-IMT. No significant associations were found between the identified dietary patterns and AD or carotid plaque.ConclusionsThe positive association between the Western diet and CCA-IMT was robust under different dietary pattern derivation methods. The adoption of a diet low in red meat, processed meat, deep-fried products, and sugar-sweetened beverages among midlife women is associated with a lower future risk of atherosclerosis.
