Are COVID-19 models blind to the social determinants of health? A systematic review protocol.

Introduction: Infectious disease models are important tools to inform public health policy decisions. These models are primarily based on an average population approach and often ignore the role of social determinants in predicting the course of a pandemic and the impact of policy interventions. Ignoring social determinants in models may cause or exacerbate inequalities.

Using mixed-method feasibility studies to examine the impact of a mobile standing desk on undergraduates' sedentary time.

Objectives: To understand experiences with and measure the effect of mobile standing desks (MSD) on undergraduates' sedentary time (ST).

Participants: Two samples of full-time undergraduates in Fall 2018.

Methods: Study 1 ( = 21): baseline average daily ST was measured via activPAL4 inclinometers and the NIGHTLY-WEEK-U questionnaire for 7 days.

Sedentary time among undergraduate students: A systematic review.

To systematically review and synthesize all relevant literature to assess the range of average daily sedentary time (ST) of undergraduate students enrolled in university and college programs across the world. Published, peer-reviewed articles were included if they: (a) were in English; (b) had a study population that consisted entirely of undergraduate students; (c) reported a daily or weekly ST for undergraduate students; and (d) included a measure of ST using a valid sedentary behavior questionnaire or accelerometers. Twenty-three studies were included in the review.
