Discretionary foods that are energy-dense and nutrient-poor contribute to over one third of total energy intake in Australian children and adults, and the typical portion sizes of many discretionary foods have increased significantly in the last two decades ⁽¹⁾ . The portion size norms (described as a typical perception of how much of a given food...
Ecological momentary assessment (EMA) may be a valid and acceptable method of assessing dietary intake in young adults ⁽¹⁾ . EMA may overcome some of the limitations associated with traditional dietary assessment methods such as high respondent burden and memory biases ⁽²⁾ by capturing time-sensitive data via concise dietary surveys. However, most...
Background: Sleep, physical activity, and nutrition (SPAN) are key determinants of both life expectancy (lifespan) and disease-free life expectancy (healthspan) yet are often studied and promoted in isolation. This study examined the joint association of these three behaviours with lifespan and healthspan.
Methods: Prospective cohort analysis of 59...
