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.

The purpose of this study was to examine the relationships between physical activity and physical fitness and adiposity in a sample of 77 girls, aged 10–11 years. Physical activity was assessed by 7-day physical activity recall by which children reported how much time they spent on low and moderate-to-vigorous physical activities. Physical fitness was measured by EUROFIT test battery. Adiposity was estimated by sum of five skinfolds. The main finding of the study was that moderate-to-vigorous physical activity and adiposity were significant predictors (with 16–34% accounted variance) of physical fitness tests where the body mass affects performance. Indicators of physical activity and adiposity were not significantly related with fitness items requiring muscular strength, balance, flexibility, and speed of limb movement. Furthermore, moderate-to-vigorous physical activity and aerobic fitness predicted 22% of variance in adiposity in girls.

The main goal of the current study was to compare physical activity levels during swimming and nonswimming elementary physical education classes. We conducted a preliminary study and found that the System for Observing Fitness Instruction Time (SOFIT) could be used to register physical activity engagement levels in swimming classes. Thirty-nine classes, involving 8- to 12-year olds, participated in one swimming and one nonswimming physical education class. Classes were videotaped and physical activity levels for 234 students were quantified using SOFIT. Students engaged in more moderate-to-vigorous physical activity during swimming classes than during nonswimming classes. As a consequence, we advocate the inclusion of swimming lessons in physical education. Because the average engagement in moderate-to-vigorous physical activity was lower than the recommended 50% in 41% of swimming classes and in 77% of the nonswimming classes, however, comprehensive efforts are needed to increase physical activity levels during both types of elementary physical education classes.

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.

The study aim was to evaluate the effectiveness of a 2-year health-related physical education intervention in a pretest-posttest design. Sixteen elementary schools (764 pupils, mean age: 11.2 ± 0.7) participated in the study. Schools were randomly assigned to the intervention condition (n = 8) and the control condition (n = 8). Making use of direct observation data gathered according to SOFIT (System for Observing Fitness Instruction Time), the moderate-to-vigorous physical activity engagement during physical education classes was significantly higher in the intervention condition than in the control condition. Children’s moderate-to-vigorous physical activity engagement during physical education lessons increased with 14% in the intervention condition (from 42 to 56%). No significant effects were found on the accelerometer data. The health-related physical education intervention was found to be promising in promoting physical activity during physical education classes.

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.

This study evaluated the effect of elimination and nonelimination games on objectively measured physical activity and psychosocial responses in children.
A total of 29 children in grades 4 to 6 (65.5% male; 10.5 ± 1.0 years old) wore an accelerometer while participating in 2 elimination and 2 nonelimination games. Activity counts were collected using a 30-second epoch and converted to METs to determine minutes spent in sedentary behavior and light, moderate, vigorous, and moderate-to-vigorous physical activity. Self-efficacy, enjoyment, and peer-victimization were assessed on 4 occasions (before and after 2 elimination and 2 nonelimination games).
Overall, girls spent more time in sedentary behavior compared with boys. Children engaged in significantly more moderate-to-vigorous physical activity during nonelimination games compared with elimination games. Furthermore, children significantly increased self-efficacy after playing both game sessions. A significant interaction between type of game and time of measurement in the prediction of enjoyment showed that enjoyment modestly increased after elimination games and slightly decreased after nonelimination games. There were no differences in peer-victimization.
This study provides preliminary evidence that nonelimination games provide more moderate-to-vigorous physical activity compared with elimination games, but elimination games may be more enjoyable.

While most studies have focused on investigating the preventive effects of physical activity on metabolic risk, the longitudinal impacts of metabolic syndrome (MetS) on activity levels is poorly understood. This study aims to examine the influence of MetS on initial activity levels and the trajectory of activity levels in Latina and African American female children over 12 months (n = 55, 9 ± 1 years). Metabolic measures, including fat and lean tissue mass by BodPod, fasting glucose, lipids, blood pressure, and waist circumference, were collected at baseline. Moderate-to-vigorous physical activity and sedentary behavior by accelerometry were collected on a quarterly basis. There were no significant differences in either initial activity levels by MetS status (Moderate-to-vigorous physical activity: 33 ± 12 mins/day for MetS, 48 ± 28 mins/day for Non-MetS, p = .12; sedentary behavior: 408 ± 57 mins/day for MetS, 421 ± 72 mins/day for Non-MetS, p = .67). Longitudinal declines in moderate-to-vigorous physical activity (p = .038) and increases in sedentary behavior (p = .003) were found. Daily sedentary behavior increased by 82.64 more minutes in youth with MetS than in those without over one year (p = .015). This study yields the first evidence of the adverse effect of MetS on sedentary behavior. Targeted intervention strategies to reduce progressive sedentariness evident in minority youth with MetS are warranted.
