Summary: Depletion of estrogen leads to inactivity, fat accumulation, and diabetes in rodents and humans. Research has found that estrogen-sensitive neurons in the brain play a role in rebalancing energy allocation in female mice, with implications for metabolism and physical activity. Melanocortin-4 receptor signaling extends beyond regulation of food intake, impacting physical activity levels and offering potential targets for intervention in obesity.

Summary: This study aimed to develop a regression equation to predict physical activity energy expenditure (PAEE) using accelerometry. Children aged 11-13 years were recruited and randomly assigned to validation (n = 54) and cross-validation (n = 25) groups. The final prediction equation (PAEE = [0.001CPM] - 0.112) accounted for 70.6% of the variance and was found to be valid for use in Sri Lankan children.

Summary: This study retrospectively evaluated the treatment of children with HO with dextroamphetamine. The results showed that dextroamphetamine treatment can improve BMI, decrease hyperphagia, and improve energy level and behavior in some patients. However, some patients experienced side effects such as hypertension during treatment. Future studies are needed to further validate these findings.

Summary: This study examined the effects of lifestyle factors on the BMI of Saudi students aged 10-15 years. The results showed that boys had a higher prevalence of overweight and obesity compared to girls, and they were more likely to skip breakfast, sleep longer, and engage in more physical activity. On the other hand, girls were less sedentary and used smartphones more frequently. Using laptops and playing video games were identified as the key sedentary activities that influenced BMI.

Summary: Children and adolescents are not engaging in enough physical activity to benefit their health. Technology-based initiatives, such as wearable devices, have been shown to encourage physical activity among this population. This review examines the impact of commercially available wearable devices on physical activity and health in children and adolescents, based on the self-determination theory. Eleven studies were included in the review, indicating that wearable devices had a positive influence on daily levels of moderate-to-vigorous physical activity, step counts, and sedentary behavior.

Summary: The purpose of this study was to determine the validity and reliability of a scientific research device, BG2, which combines heart rate variability with an acceleration sensor, for estimating time spent in different intensity zones during free-living activities. The results showed that BG2 estimated physical activity more accurately than Bouchard, especially in moderate to vigorous physical activity. The findings suggest that BG2 is a valid and reliable tool for assessing activity levels in free-living conditions.

Summary: Individuals with Anorexia Nervosa are often described as restless, hyperactive and having disturbed sleep. The study aimed to quantify the physical activity and sleep behavior of anorexia nervosa patients and to increase result reproducibility and generalisability. Most patients spent most of their time inactive at the beginning of treatment and failed to meet sleep recommendations.

Summary: This study evaluated the concurrent validity of the Apple Watch 3 in estimating moderate-to-vigorous physical activity (MVPA) time and active energy expenditure (AEE) in school-aged children under simulated and free-living conditions. The Apple Watch provided comparable estimates for MVPA time and AEE during the simulated free-living condition, but had relatively large variability in estimating AEE in children. The Apple Watch was statistically equivalent to the K5 within a certain range for MVPA time and AEE estimates.

Summary: Physical activity becomes more fragmented with age, and poorer energy cost and capacity may be associated with this. Higher cost-to-capacity ratio and lower energy capacity may lead to more fragmented physical activity, especially among those less active or aged >= 70 years.

Summary: This study aimed to analyze the accuracy of Evenson cut-points for estimating moderate-to-vigorous intensity physical activity (MVPA) and sedentary behavior (SB) in children and adolescents with disabilities, as well as to define new equations for estimating energy expenditure (EE) in this population, particularly in those with cerebral palsy (CP). Specific GT3X+ cut-points were also defined for estimating MVPA in individuals with CP. The results indicate that using specific ActiGraph GT3X+ cut-points is accurate for estimating MVPA levels in children and adolescents with disabilities, especially those with CP, at least in laboratory conditions.

Summary: The idea of increasing physical activity directly adding to total energy expenditure (TEE) in humans is challenged by the energy constrained hypothesis. Evidence supporting this hypothesis is limited due to various methodological issues, and future studies should address these limitations by using randomized controlled trials. The available evidence suggests that increasing physical activity mostly has an additive effect on TEE, although some energy remains unaccounted for, and the degree of energy balance may further moderate this effect.

Summary: The study aimed to investigate the association of water turnover and total energy expenditure with physical activity and body composition in Japanese preschool children. Results showed that WT and TEE were moderately positively correlated with body weight, fat-free mass, and exercise duration.

Summary: The aim of this study was to determine the minimum number of monitoring days required for reliable estimates of different physical activity (PA) intensities in cancer survivors. Results showed that two monitoring days were needed for reliable estimates of light PA, three monitoring days were needed for moderate and moderate-to-vigorous PA. Reliable estimates for vigorous PA could not be obtained for the overall sample, but were obtained for breast cancer survivors. Shorter monitoring periods with wearable devices may provide reliable estimates and reduce participant burden.

Summary: This study examined the association of adipokines (leptin, adiponectin), hs-CRP, and IL-6 with cardiovascular risk factors in children and adolescents with T1D. The results showed positive associations of leptin with BMI, fat mass, and hip circumference, as well as negative associations of adiponectin with BMI and muscle mass. Hs-CRP was associated with weight, fat mass, and BMI. Leptin, adiponectin, and hs-CRP could be used as prognostic indicators of cardiovascular risk in children with T1D.
