Increased physical activity (PA) affects outcomes in patients with anorexia nervosa (AN). To objectively assess PA patterns of hospitalized AN patients in comparison with healthy, outpatient controls (HC), and to analyze the effect of PA on Body Mass Index (BMI) change in patients with AN, we measured PA in 50 female patients with AN (median age = 25 years, range = 18–52 years; mean BMI = 14.4 ± 2.0 kg/m2) at the initiation of inpatient treatment and in 30 female healthy controls (median age = 26 years, range = 19–53 years; mean BMI = 21.3 ± 1.7 kg/m2) using the SenseWear™ armband. Duration of inpatient stay and weight at discharge were abstracted from medical records. Compared with controls, AN patients spent more time in very light-intensity physical activity (VLPA) (median VLPA = 647 vs. 566 min/day, p = 0.004) and light-intensity physical activity (LPA) (median LPA = 126 vs. 84 min/day, p < 0.001) and less time in moderate-intensity physical activity (MPA) (median MPA = 82 vs. 114 min/day, p = 0.022) and vigorous physical activity (VPA) (median VPA = 0 vs. 16 min/day, p < 0.001). PA and BMI increase were not associated in a linear model, and BMI increase was mostly explained by lower admission BMI and longer inpatient stay. In a non-linear model, an influence of PA on BMI increase seemed probable (jack knife validation, r2 = 0.203; p < 0.001). No direct association was observed between physical inactivity and BMI increase in AN. An altered PA pattern exists in AN patients compared to controls, yet the origin and consequences thereof deserve further investigation.

Sedentary Activities

Introduction: Regular physical activity in childhood and adolescence is important for promoting lifelong health and well-being and preventing various health conditions. The 2008, Physical Activity Guidelines for Americans recommended that children and adolescents aged 6 to 17 years should have 60 minutes (1 hour) or more of moderate and vigorous intensity physical activity each day. Unfortunately, many children and adolescents do not meet the recommendations set forth by the guidelines. Aim: To study the physical activity levels and its impact on body mass index (BMI). Methodology: 420 subjects were selected by purposive random sampling method from 5 schools of Mumbai. Physical activity levels of the samples were assessed through the physical activity questionnaire and the height and weight of all the samples were taken to calculate the BMI. Results: It was observed that 39.5% performed sedentary activities for on an average of 0-1 hr/week. Similarly, 74.2% subjects performed moderate to high intensity activities for an average of 0-1 hr/week. Maximum % of subjects (48%) spent 1-2hr/week in performing sedentary activities whereas, when compared to moderate to high intensity activities maximum % of subjects performed only for 0-1 hr/week. Only 116 subjects met the daily requirements of moderate to high intensity physical activity. A total of 33.2% of samples were observed to be under the three categories of wasting (mild, moderate and severe respectively) as per WHO standards.

Abstract Introduction. Due to coronavirus disease 2019 (COVID-19) many people give up exercises. International physical activity guidelines recommend 150 minutes per week of moderate- to vigorous-intensity physical activity or 75 minutes at high intensity per week. Healthy adults should take 10,000 steps per day. Wearable devices (smartwatches, step counters, physical activity monitoring applications) have the potential to promote a healthy lifestyle at the time of COVID-19 pandemic. They are accepted by the youth. Aim. The aim of the study was to find out if using step counting devices affects the level of physical activity and body mass index (BMI) in students. Material and methods. A total of 303 participants (227 women, 76 men) studying in Lublin, Poland of mean age 19.5 years participated in the study conducted with use of an internet questionnaire. Results. Before the COVID-19 pandemic their mean BMI was 22.17 kg/m2 and after 9 months of COVID-19–related restrictions it was 22.57 kg/m2. Among the respondents 204 (67.3%) did a physical activity for 50 min 3 times a week in 2019 and 99 (32.7%) did not. In December 2020 there was a significant decrease in the number of students doing physical activity to 128 (42.2%) (p<0.05) and an increase in the number of students who did not do any physical activity to 175 (57.8%) (p<0.05). In 2019 as many as 110 (36.3%) of the respondents used to use step counting devices and 192 (63.7%) did not. In 2020 the number of students using activity tracking devices significantly decreased to 58 (19.2) (p<0.05). The number of students who did not use any step counting device in 2020 was 245 (80.8%). Conclusion. Due to the COVID-19 pandemic the number of students who don’t do enough physical activity significantly increased. The use of step counting devices helps students in continuing physical activity despite COVID-19-related restrictions.

Purposes: To examine the association between sedentary time (ST) and light physical activity (LPA), moderate- to vigorous-intensity physical activity (MVPA), and body mass index (BMI), and to track these behaviors over a 3-year follow-up in young schoolchildren. Methods: The final sample was 64 children (female: n = 36 or 56.3%), enrolled in schools in Porto, Portugal. Height and mass of children were measured by standard methods, and BMI was then calculated. ST, LPA, and MVPA were measured by accelerometer. Changes (Δ) and relative changes (Δ%) between 2009/2010 and 2012/2013 of ST, LPA, MVPA, and BMI were computed. Multiple linear regression analyses were fit to predict Δ%ST (outcome variable), by Δ%LPA, Δ%MVPA, and Δ%BMI (exposure variables). Results: ST increased and LPA decreased significantly for whole sample (both Ps < .05). No statistically significant difference was found for MVPA over time. There were no differences for ΔST, ΔLPA, ΔMVPA, and ΔBMI between boys and girls. The Δ%LPA and Δ%MVPA were negatively associated with Δ%ST, whereas Δ%BMI was positively associated. Tracking coefficients varied from moderate to strong. Conclusions: Time spent in ST increases due to displacement of time in LPA. This reinforces public health measures and suggests the need for interventions focusing on offsetting the decline ST and increasing MVPA during childhood.
