Unlabelled: Recently, sedentary behavior recommendations have been included in the public health guidelines of multiple countries, pointing to new opportunities for prevention of chronic disease as well as a potential strategy for initiating long-term behavior change.
Objective: To propose an evidence-informed approach to physical activity counseling that starts with a focus on reducing sedentary time.
Methods: We put forward a case for addressing changes in sedentary behavior in clinical practice using a narrative review. We also propose a new approach for the assessment and counselling of patients with respect to movement behaviors.
Results: There is evidence to support a stepwise approach to physical activity counseling that starts with targeting sedentary behavior, particularly in those who are highly sedentary, or those who have chronic disease, or physical impairments.
Conclusions: Our approach encourages clinicians to consider sedentary behavior counseling as a critical first step to physical activity counseling. For many patients, this initial step of reducing sedentary behavior could build a pathway to an active lifestyle.
Practical Implications: A shift from long periods of sedentary time to daily routines incorporating more light intensity physical activity could result in meaningful health improvements. Importantly, this approach may be more feasible for highly inactive patients.

: Television viewing has been linked with increased weight and obesity, likely through decreased physical activity associated with sitting and viewing television, as well as increased intake of food, likely through reduced awareness of eating and intake behaviours. This review sought to determine the effects of television viewing on energy intake relative to the absence of television. : We adhered to the PRISMA guidelines and pre-registered this review in PROSPERO (CRD42023493092).

Background/objectives: The study prospectively assessed the association between sleep duration and the consumption of ultra-processed foods in adolescent students from a Brazilian capital.
Methods: We observed 1431 adolescents participating in the Longitudinal Study on sedentary behavior, physical activity, dietary habits, and adolescent health, aged 10 to 14 years, in the years 2014 to 2017. The percentage of consumption of ultra-processed foods was evaluated by the Friedman test.

Physical inactivity and sedentary behavior are associated with higher risks of age-related morbidity and mortality. However, whether they causally contribute to accelerating biological aging has not been fully elucidated. Utilizing the largest available genome-wide association study (GWAS) summary data, we implemented a comprehensive analytical framework to investigate the associations between genetically predicted moderate-to-vigorous leisure-time physical activity (MVPA), leisure screen time (LST), and four epigenetic age acceleration (EAA) measures: HannumAgeAccel, intrinsic HorvathAgeAccel, PhenoAgeAccel, and GrimAgeAccel.

Importance: Data characterizing the severity and changing prevalence of bone mineral density (BMD) deficits and associated nonfracture consequences among childhood cancer survivors decades after treatment are lacking.
Objective: To evaluate risk for moderate and severe BMD deficits in survivors and to identify long-term consequences of BMD deficits.
Design, Setting, And Participants: This cohort study used cross-sectional and longitudinal data from the St Jude Lifetime (SJLIFE) cohort, a retrospectively constructed cohort with prospective follow-up.

Background: The COVID-19 pandemic has profoundly affected the physical activity (PA) levels and dietary habits of individuals, particularly children and adolescents in Saudi Arabia, owing to widespread closures and social distancing measures, including school closures.
Methods: A cross-sectional study was conducted to assess the impact of distance learning (DL) on PA and dietary habits among public middle school girls during the pandemic. The Arab Teens Lifestyle Questionnaire (ATLS) was used to assess habitual PA, sedentary behavior, and dietary habits.
