Participants in the DDM-Spain/var-DDM study, which included 2878 middle-aged Spanish women, were interviewed via telephone and asked questions on sleep characteristics. Two radiologists assessed MD in their left craneo-caudal mammogram, assisted by a validated semiautomatic-computer tool (DM-scan). We used log-transformed percentage MD as the dependent variable and fitted mixed linear regression models, including known confounding variables. Our results showed that neither sleeping patterns nor sleep disorders were associated with MD. However, women with frequent changes in their bedtime due to anxiety or depression had higher MD (e(beta):1.53;95%Cl:1.04-2.26).engAMhttp://creativecommons.org/licenses/by-nc-nd/4.0/Sleep patternsSleep disordersBreast cancerMammographic densityBreast NeoplasmsAgedBreastSpainFemaleRisk FactorsHumansMammographyBreast DensityMiddle AgedCross-Sectional StudiesSleep Wake DisordersSleep patterns, sleep disorders and mammographic density in spanish women: The DDM-Spain/Var-DDM studyAttribution-NonCommercial-NoDerivatives 4.0 International2836486299105-10810.1016/j.maturitas.2017.02.0151873-4111Maturitasopen accessDensidad de la MamaEstudios TransversalesFactores de RiesgoTrastornos del Sueño-VigiliaHumanosPersona de Mediana EdadMamaMamografíaAncianoFemeninoNeoplasias de la MamaEspaña2-s2.0-85014849803400223500017L614724241
