Purpose:　Sleep　disorders　are　common　globally.　Probiotics　may　improve　human　microbial　diversity,　offering　potential　benefits　for　sleep　disturbances　by　enhancing　sleep　quality　and　reducing　disorders.　We　aimed　to　use　a　population-based　study　to　investigate　the　association　between　yogurt　(a　probiotic　food)　and　probiotic　consumption　with　sleep　disturbances　in　US　adults.　Methods:　A　total　of　49,693　adults　from　the　2009-2018　National　Health　and　Nutrition　Examination　Survey　(NHANES)　were　included　in　the　analyses.　Sleep　disorders　and　sleep　duration　were　assessed　according　to　the　Sleep　Disorders　Questionnaire.　The　Dietary　Questionnaire　evaluated　yogurt　and　dietary　supplements　containing　probiotic　consumption.　After　adjusting　for　confounding　factors,　weighted　multivariable　logistic　regression　and　subgroup　analyses　were　used　to　assess　the　association　between　yogurt　and　probiotic　consumption　and　sleep　status.　Results:　Of　the　study　cohort,　3535　(14.24　%)　participants　consumed　yogurt　and/or　dietary　supplements　containing　probiotics.　The　prevalence　of　sleep　disorders　was　16.22　%.　Only　53.51　%　of　the　participants　achieved　the　recommended　amount　of　sleep　(7-9　h),　with　6.10　%　and　33.48　%　having　excessive　and　insufficient　sleep　duration,　respectively.　Weighted　Logistic　regression　models　indicated　a　significant　association　of　probiotic　intake　with　a　decreased　risk　of　sleep　disturbances　compared　with　those　without　yogurt　or　probiotic　consumption　after　adjustments.　(For　sleep　disorders:　OR:　0.96,　95　%　CI　0.94-0.98,　P　＜　0.001;　for　sleep　duration:　OR:　0.98,　95　%　CI　0.96-1.00,　P　=　0.081)　Moreover,　the　effect　size　of　the　probiotic　intake　on　sleep　was　especially　significant　in　sex,　race,　and　BMI　subgroups.　Conclusion:　The　present　study　first　indicated　that　yogurt　and　probiotic　consumption　were　associated　with　a　reduced　risk　of　sleep　disturbances　in　US　adults,　particularly　among　males,　whites,　and　those　with　a　normal　BMI.　Incorporating　yogurt　or　probiotics　into　the　diet　could　serve　as　a　public　health　strategy　for　improving　sleep　disturbances,　though　further　investigation　into　the　underlying　mechanisms　is　needed.
