The World Health Organization together with the Institute of Medicine recommend at least 60 minutes of moderate to vigorous physical activity (MVPA) for children and youth aged 5 to 17 years. 1 , 2 Results of the 2013/2014 cross-national Health Behavior in School-Aged Children study showed that 21

Research has shown that decreases in health-related fitness (fitness) may increase school absenteeism. 1 , 2 The fitness-physical activity association is well established, 3 including an improved cardiometabolic risk profile in youth who engage in moderate to vigorous physical activity daily. 4

Therefore, the objective of this study is to examine: (1) the relationship between parental stress and adolescents’ moderate to vigorous

Approximately three quarters of the children between 6 and 17 years of age are not meeting the recommended physical activity requirements of 60 min of moderate to vigorous physical activity (MVPA) per day ( Child & Adolescent Health Measurement Initiative, 2016 ). These low physical activity rates

This study examined associations between perceived neighborhood environment and physical activity among frail older adults and whether these associations are moderated by fear of falling. Participants were 238 frail older adults. Daily step counts and duration of moderate-to-vigorous physical activity were measured using an accelerometer. Participants completed the abbreviated Neighborhood Environment Walkability Scale; fear of falling and demographic and health-related factors were measured by a questionnaire. The interaction between crime safety and fear of falling was significantly associated with step count (p = .009) and moderate-to-vigorous physical activity (p = .018) in multiple regression analysis. Stratified according to fear of falling, crime safety was significantly associated with steps (p = .007) and moderate-to-vigorous physical activity (p = .030) in the low fear of falling group. The results suggest that crime safety is associated with physical activity among frail older adults, and this association is moderated by fear of falling.

Physical activity is important for maintaining independence and quality of life in older people living in care homes. Little is known about patterns of physical activity or sedentary behavior in this population.
Thirty-three care home residents (82.6 ± 9.2 years) wore an ActiGraph GTX3 accelerometer for seven days, which provided minutes of sedentary behavior and low, light, and moderate-to-vigorous physical activity. Participants undertook the Mini-Mental State Examination and care staff reported activities of daily living (Barthel index) and functional ambulation classification (FAC) for each participant.
Participants spent on average 79% of their day sedentary, 14% in low, 6% in light, and 1% in moderate-to-vigorous physical activity. Activity levels did not significantly differ between days or hours of the day (P > .05).
Levels of physical activity were very low and time being sedentary was high. This study can inform physical activity and sedentary behavior interventions for care homes’ residents.

To examine the association between accelerometer-assessed physical activity and visual acuity among a nationally representative sample of adults with evidence of diabetes.
Six hundred seventy adult participants with diabetes (age 20 to 85) from the 2003–2006 NHANES cycles constituted the analyzed sample. Participants wore an accelerometer for 7 days to quantify time spent in sedentary behavior, light-intensity physical activity and moderate-to-vigorous physical activity. Visual acuity was objectively assessed for each eye.
In multivariable models, every 1-hour increment in daily sedentary behavior was associated with 23% greater likelihood (OR = 1.23; 95% CI: 1.01–1.52) of having uncorrected refractive error as opposed to normal sight. Performing more than 5 minutes of daily moderate-to-vigorous physical activity was associated with a 82% lower likelihood of having vision impairment as opposed to normal sight (OR = 0.18; 95% CI: 0.06–0.50) while every 1-hour increment in daily light-intensity physical activity was, after adjustments, independently associated with a 38% lower likelihood of vision impairment (OR = 0.62; 95% CI: 0.42–0.92).
People with diabetes spending more time in sedentary behavior and less time performing light or moderate-to-vigorous physical activity are more likely to have poorer vision.
