Conducting 24-hour movement behaviour research with preschool children in middle-income countries: Lessons from the SUNRISE pilot study in Mexico.

Objectives: Movement behaviour research among preschoolers is nascent in low- and middle-income countries, where levels of physical activity, sleep, and sedentary behaviour in children are largely unknown. This study aimed to adapt and assess the acceptability and feasibility of the International Study of Movement Behaviours in the Early Years (SUNRISE) in Mexico, and report on challenges and solutions while implementing the protocol.

Study Design: Pilot study of the SUNRISE protocol in Mexico.

Evaluation of renal functional reserve with oral protein load or new ultrasound test.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

Comparison of Physical Activity and Sedentary Behaviour Patterns by Sex, Geographical Location, and Time of the Week in Mexican Adolescents.

Excess sedentary behaviour (SB) and insufficient physical activity have been identified as risk factors for cardiometabolic diseases in adolescents, and some factors may affect how much time they spend on these activities. This study sought to compare the SB and PA patterns as well as compliance with PA recommendations by sex, geographical location, and time of the week in Mexican adolescents. In a cross-sectional design, we objectively assessed SB and PA in 106 adolescents (15 to 18 y) through waist-worn accelerometers for one week.

The co-benefits of active travel interventions beyond physical activity: a systematic review.

Active travel is a widely recognised strategy for promoting active living but its co-benefits beyond increasing physical activity, such as broader health, environmental, and social benefits, have rarely been synthesised. We conducted a systematic review to examine the co-benefits of active travel interventions. Following a preregistered protocol (PROSPERO CRD42022359059), we identified 80 studies for the search period from Jan 1, 2000, to Sept 13, 2022.
