“…Some observational studies have reported significant associations between prolonged sitting and adverse health outcomes in 10- to 14-year-old children [17]. Similar findings have been reported in specific subgroups such as boys [18], children with low physical activity levels [19] or children with a family history of obesity [20].…”

BackgroundThis study examined the frequency of and differences in sedentary bouts of different durations and the total time spent in sedentary bouts on a weekday, a weekend day, during school hours, during after-school hours and in the evening period in a sample of 10- to 12-year-old Belgian children.MethodsAccelerometer data were collected as part of the ENERGY-project in Belgium (n = 577, 10.9 ± 0.7 years, 53% girls) in 2011. Differences in total sedentary time, sedentary bouts of 2–5, 5–10, 10–20, 20–30 and ≥30 min and total time accumulated in those bouts were examined on a weekday, a weekend day, during school hours, during after-school hours and in the evening period, using multilevel analyses in MLwiN 2.22.ResultsMore than 60% of the participants’ waking time was spent sedentary. Children typically engaged in short sedentary bouts of 2–5 and 5–10 min, which contributed almost 50% towards their total daily sedentary time. Although the differences were very small, children engaged in significantly fewer sedentary bouts of nearly all durations during after-school hours compared to during school hours and in the evening period. Children also engaged in significantly fewer sedentary bouts of 5–10, 10–20, and 20–30 min per hour on a weekend day than on a weekday.ConclusionsAlthough primary school children spend more than 60% of their waking time sedentary, they generally engaged in short sedentary bouts. Children’s sedentary bouts were slightly longer on weekdays, particularly during school hours and in the evening period, although the differences were very small. These results suggest that in this age group, interventions focusing on reducing total sedentary time rather than interrupting prolonged sedentary time are needed.Electronic supplementary materialThe online version of this article (doi:10.1186/s12887-017-0894-9) contains supplementary material, which is available to authorized users.

“…The remaining six studies (21%) [ 14 , 56 – 60 ] presented both. Fourteen of the 29 included studies (48%) adjusted for either total MVPA [ 14 , 33 , 36 , 38 , 40 – 42 , 58 ], sedentary time [ 60 ], or both MVPA and sedentary time [ 34 , 37 , 45 , 48 , 59 ]. The remaining 15 studies examined activity patterns without adjustment for total volume of sedentary time and/or physical activity [ 35 , 39 , 43 , 44 , 46 , 47 , 49 – 57 ].…”

Associations between activity patterns and cardio-metabolic risk factors in children and adolescents: A systematic review

et al. 2018

View full text Add to dashboard Cite

IntroductionTotal volumes of physical activity and sedentary behaviour have been associated with cardio-metabolic risk profiles; however, little research has examined whether patterns of activity (e.g., prolonged bouts, frequency of breaks in sitting) impact cardio-metabolic risk. The aim of this review was to synthesise the evidence concerning associations between activity patterns and cardio-metabolic risk factors in children and adolescents aged 5–19 years.Materials and methodsA systematic search of seven databases was completed in October 2017. Included studies were required to report associations between objectively-measured activity patterns and cardio-metabolic risk factors in children and/or adolescents, and be published between 1980 and 2017. At least two researchers independently screened each study, extracted data, and undertook risk of bias assessments.ResultsFrom the 15,947 articles identified, 29 were included in this review. Twenty-four studies were observational (cross-sectional and/or longitudinal); five were experimental. Ten studies examined physical activity patterns, whilst 19 studies examined sedentary patterns. Only one study examined both physical activity and sedentary time patterns. Considerable variation in definitions of activity patterns made it impossible to identify which activity patterns were most beneficial to children’s and adolescents’ cardio-metabolic health. However, potential insights and current research gaps were identified.Discussion and conclusionA consensus on how to define activity patterns is needed in order to determine which activity patterns are associated with children’s and adolescents’ cardio-metabolic risk. This will inform future research on the impact of activity patterns on children’s and adolescents’ short- and longer-term health.

“…Studies that have examined the association between physical activity and blood pressure in children have had inconsistent findings, with some showing that more time spent being active [ 15 – 25 ], and less time spent in sedentary behaviours [ 16 , 17 , 25 , 26 ], are associated with lower blood pressure or reduced risk of hypertension, and others finding no association between physical activity and blood pressure [ 27 – 33 ]. Several of these studies have been limited by self-reported measures of physical activity and sedentary time, both of which are subject to recall bias [ 15 , 18 , 19 , 32 ].…”

A longitudinal study of the associations of children's body mass index and physical activity with blood pressure

et al. 2017

Childhood blood pressure is a marker of cardiovascular disease risk in later life. We examined how body mass index (BMI) and physical activity, and changes in these, are associated with blood pressure in primary school-aged children. Data are from 1223 children aged 9 years (Year 4) in Bristol, UK, 685 of whom had been assessed at 6 years (Year 1). Child height and weight were measured, and children wore accelerometers for five days, from which average counts per minute, and moderate-to-vigorous-intensity physical activity and sedentary minutes per day were derived. At age 9 years, blood pressure was measured. Multiple imputation of missing data and adjusted linear regression models were used to examine associations. Child BMI at 9 years was cross-sectionally associated with higher systolic (SBP) and diastolic (DBP) blood pressure (mean difference [95% CI]: 1.10 [0.34, 1.87] mmHg and 0.86 [0.13, 1.60] mmHg, respectively, per SD of BMI). Prospective associations of BMI at age 6 with blood pressure at age 9 were consistent with these cross-sectional associations. However, change in BMI between 6 and 9 years was not strongly associated with subsequent SBP or DBP (0.68 [-0.61, 1.98] mmHg and 1.23 [-0.09, 2.54] mmHg, respectively). There was little evidence that physical activity or sedentary time were associated with blood pressure in either cross-sectional or prospective analyses. Greater childhood BMI is associated with higher blood pressure, and this association persists over several years. Prevention of excessive bodyweight from early childhood may be important in stemming the development of cardiovascular risk.
