Behavioral-Social Rhythms and Cardiovascular Disease Risk in Retired Night Shift Workers and Retired Day Workers

More regular behavioral-social rhythms are associated with lower odds of metabolic syndrome in retired adults.

• A higher Social Rhythm Metric score correlated with reduced odds of metabolic syndrome (odds ratio = 0.57).
• Increased intradaily variability in rest-activity rhythms was associated with higher odds of metabolic syndrome (odds ratio = 4.00).
• Greater interdaily stability in rest-activity rhythms linked to lower odds of metabolic syndrome (odds ratio = 0.42).
• Regular behavioral-social rhythms were connected to lower odds of high body mass index and higher high-density lipoprotein cholesterol.
• Past night shift work exposure did not influence the relationship between behavioral-social rhythms and metabolic syndrome.
