“…There are no comparable data in the literature for children who were born VLBW. However, in a sample of 11 to 12‐year‐old predominantly term‐born children from Australia (n = 938), a 15‐minute reallocation of objectively measured sedentary time to MVPA was associated with 1.2% (95% CI 0.9 to 1.5) increase in total fat‐free mass measured by bioelectrical impedance . Moreover, our results are similar to studies using traditional linear regression modelling.…”

Summary Background Few studies have investigated how lifestyle is associated with body composition in children born very low birth weight (VLBW, <1500 g), a population at increased risk of obesity and metabolic syndrome in later life. Objectives Determine how time spent in physical activity, sedentary time, and sleep are associated with body composition in children born VLBW. Methods In this prospective cohort study of 5.5‐year‐old children born VLBW, height, weight, body composition (skinfolds, air displacement plethysmography), and 7 days of movement data (logbooks and accelerometers) were collected. Results Of 158 participants, 53% were male, and mean (SD) birth weight was 1013 (264) g. Only 52% achieved 60 minutes/day of moderate‐to‐vigorous physical activity, but 96% achieved sleep recommendations. Reallocating 30 minutes of sedentary time to light physical activity (LPA) was associated with 0.20 kg/m2 (95% CI, 0.02 to 0.37) greater fat‐free mass index. An equivalent inverse association was found when reallocating LPA to sedentary time. No associations were found for other movement behaviours. Conclusions Promoting LPA and reducing sedentary time may be an important strategy in reducing the elevated risk of obesity and metabolic syndrome amongst those born VLBW by supporting lean mass accretion.

“…A strength of this study was that we used the CoDA approach, which adequately deals with the compositional properties of time-use data. Although in recent years several studies used the CoDA approach to assess the associations between device-measured SB and obesity markers [19,[40][41][42][43][44], to our knowledge there has been no CoDA-based study analyzing the effect of sedentary patterns on adiposity in children.…”

Background: Between-person differences in sedentary patterns should be considered to understand the role of sedentary behavior (SB) in the development of childhood obesity. This study took a novel approach based on compositional data analysis to examine associations between SB patterns and adiposity and investigate differences in adiposity associated with time reallocation between time spent in sedentary bouts of different duration and physical activity. Methods: An analysis of cross-sectional data was performed in 425 children aged 7-12 years (58% girls). Waking behaviors were assessed using ActiGraph GT3X accelerometer for seven consecutive days. Multi-frequency bioimpedance measurement was used to determine adiposity. Compositional regression models with robust estimators were used to analyze associations between sedentary patterns and adiposity markers. To examine differences in adiposity associated with time reallocation, we used the compositional isotemporal substitution model. Results: Significantly higher fat mass percentage (FM%; β ilr1 = 0.18; 95% CI: 0.01, 0.34; p = 0.040) and visceral adipose tissue (VAT; β ilr1 = 0.37; 95% CI: 0.03, 0.71; p = 0.034) were associated with time spent in middle sedentary bouts in duration of 10-29 min (relative to remaining behaviors). No significant associations were found for short (< 10 min) and long sedentary bouts (≥30 min). Substituting the time spent in total SB with moderate-to-vigorous physical activity (MVPA) was associated with a decrease in VAT. Substituting 1 h/week of the time spent in middle sedentary bouts with MVPA was associated with 2.9% (95% CI: 1.2, 4.6), 3.4% (95% CI: 1.2, 5.5), and 6.1% (95% CI: 2.9, 9.2) lower FM%, fat mass index, and VAT, respectively. Moreover, substituting 2 h/week of time spent in middle sedentary bouts with short sedentary bouts was associated with 3.5% (95% CI: 0.02, 6.9) lower FM%. Conclusions: Our findings suggest that adiposity status could be improved by increasing MVPA at the expense of time spent in middle sedentary bouts. Some benefits to adiposity may also be expected from replacing middle sedentary bouts with short sedentary bouts, that is, by taking standing or activity breaks more often. These findings may help design more effective interventions to prevent and control childhood obesity.

“…Findings from recent studies measuring exercise, screen time, snacking, and sleep show that the frequency of eating along with parenting style is to blame for the increase in caloric uptake in Australian children. 15,16 These studies found positive associations with an increase in consumption of energy-dense foods, lower levels of physical activity, frequent television viewing, and computer use. Children as young as 11 are spending more time in front of screens, and less time on physical activity resulting in poorer body composition.…”

“…Children as young as 11 are spending more time in front of screens, and less time on physical activity resulting in poorer body composition. 16 Another problematic trend is that overweight is now regarded as normal, and studies report that people do not recognise that they are overweight. 17 Being surrounded by friends and family who are also overweight or obese has a normalising affect and promotes a misperception of a healthy body weight image and a lesser inclination to address the issue.…”

Being overweight is now the norm. It is hypothesised eating between meals is a significant part of the problem. Habits that are part of social intercourse are implicated in obesity insofar as those who opt for caffeinated drinks when socialising between meals are also more likely to concurrently consume high energy-dense snacks. The consumption of sugar as a contributor to obesity is well established and experts also agree that the habit of eating for pleasure rather than hunger is strongly implicated in weight gain. Such habitual eating patterns may offer opportunity for feasible lifestyle change when framed appropriately. A promising strategy involves visualising avatars of a healthier future self as well as identifying the circumstances in which threats to that outcome can be tackled immediately. Though promising, there is limited evidence that such a strategy can be effective yet.
