Mizzou study to test couples’ routines and blood glucose

University of Missouri researchers have launched an NIH-funded study that will test whether couples’ sleep patterns, daily routines and relationship experiences are associated with changes in blood glucose and heart disease risk. The project, led by Eunjin Tracy, focuses on couples in which at least one partner has type 2 diabetes. It is a planned study with no health findings yet reported: the announcement describes the research questions, measurements and hypothesis, rather than demonstrating that one partner’s habits affect the other’s metabolic health.

Tracy, a researcher in Mizzou’s College of Education and Human Development and a member of its Department of Human Development and Family Science, said the team wants to understand how intertwined daily experiences may be reflected in physical health. Researchers will examine patterns in sleep, routines and relationship quality, asking whether they are related to changes in blood glucose and ultimately to heart disease risk. The study will also assess whether changes in one partner’s daily life correspond with changes in the other partner’s experiences or blood glucose.

These are questions the planned research is designed to investigate, not established connections reported by the grant announcement. Both partners in each participating couple will wear devices for 20 days to track sleep and continuous glucose levels. They will also report on their daily routines and relationship experiences.

Investigators will analyze the measurements together, comparing changes in each person’s daily life with the other partner’s experiences and glucose levels. Routine consistency refers to the regularity of an individual partner’s habits rather than whether both partners follow the same schedule. For example, one partner might regularly go to bed at 8 p.m. while the other goes to bed at 10 p.m.; the study is intended to examine how each person’s routine fits within the couple’s shared life.

The team’s hypothesis is that couples with stronger relationship quality and more consistent daily routines may also have healthier blood-glucose levels and therefore may be at lower risk for heart disease. That prediction remains to be tested. The announcement does not report that the researchers have already found such links, and the project is intended to measure associations among daily patterns, relationship experiences and metabolic measures.

Tracy is collaborating with Mizzou experts in nutrition and exercise physiology, psychology, medicine and statistics to examine relationships, routines and health from multiple perspectives. The team will consider whether everyday factors such as sleep timing, eating, physical activity and stress are reflected in measurable health outcomes, reflecting the shared nature of couples’ lives. Its immediate scope is couples with at least one partner who has type 2 diabetes.

If the findings support the hypothesis, the researchers say future health interventions might involve both partners and recognize that lasting behavior change can be influenced by the life a person shares with someone else; that potential application depends on results that have not yet been reported.
