Title
Association between temporal dietary patterns and sedentary behaviors in middle-aged and older adults
Summary
Sedentary behaviors (SB) are defined as any waking task with an energy expenditure of 1.5 metabolic equivalents or less. Prolonged sedentary time is independently associated with deleterious health outcomes such as all-cause mortality, cancer incidence and mortality, cardiovascular disease risk and mortality, and type 2 diabetes. Temporal dietary pattern (TDP) describes when and how much a person eats a day; dietary pattern (DP) describes the qualities of the food. Currently, there exists evidence of an association between both TDP and obesity as well as DP and SB, but it is unknown whether an association between TDP and SB exists. Prior research suggests that temporal nutritional mechanisms might explain a link between obesity, metabolic syndrome, and other complications but fail to consider how SB may play a key role in these relationships. Therefore, it is proposed to develop a model comparing TDP and SB. In the near future, we plan to expand the project to investigate if TDP and SB are associated with metabolic and inflammatory biomarkers in this cohort.
Aims

1) To investigate whether temporal dietary patterns are associated with sedentary behavior time
2) To investigate whether temporal dietary patterns are associated with metabolic and inflammatory biomarkers
3) To investigate whether sedentary behaviors are associated with metabolic and inflammatory biomarkers
