Evaluation of the ActiMotus Software to Accurately Classify Postures and Movements in Children Aged 3-14.

Background: ActiMotus, a thigh-accelerometer-based software used for the classification of postures and movements (PaMs), has shown high accuracy among adults and school-aged children; however, its accuracy among younger children and potential differences between sexes are unknown. This study aimed to evaluate the accuracy of ActiMotus to measure PaMs among children between 3 and 14 years and to assess if this was influenced by the sex or age of children.

Method: Forty-eight children attended a structured ~1-hour data collection session at a laboratory.

"I Use Technologies Strategically With My Family Now": Practices That Parents Value to Promote Physical Activity in Young Children.

Background: Although widely accessible digital technology (DT) provided multiple opportunities for young children's play, learning, and development, it also raised parents and professionals' concerns regarding its impact on children's physical activity. This study aimed to identify practices involving DT that were valued by parents in helping their young child to be physically active.

Methods: Participants were parents of ambulatory young children (less than 5 y of age) engaged with a playgroup.

Early Childhood Screen Use Contexts and Cognitive and Psychosocial Outcomes: A Systematic Review and Meta-analysis.

Importance: The multifaceted nature of screen use has been largely overlooked in favor of a simplistic unidimensional measure of overall screen time when evaluating the benefits and risks of screen use to early childhood development.

Objective: To conduct a systematic review and meta-analysis to examine associations of screen use contexts in early childhood with cognitive and psychosocial outcomes.

Data Sources: PsycINFO, Embase, MEDLINE Ovid, ProQuest, CINAHL, Web of Science, and Scopus were searched from inception to December 31, 2023.

Measurement Method Options to Investigate Digital Screen Technology Use by Children and Adolescents: A Narrative Review.

The role and potential impact of digital screen technology in the lives of children is heavily debated. Current evidence is limited by the weakness of measures typically used to characterise screen use, predominantly proxy- or self-reports with known inaccuracy and bias. However, robust and detailed evidence is needed to provide practical trustworthy guidance to families and professionals working with families.

Parental practices and perspectives on health and digital technology use information seeking for children aged 0-36 months.

Background: Parents commonly seek information to support the health and well-being of their children. The increasing availability of health information online and social changes related to the COVID-19 pandemic may have changed what information is sought, from whom, where, and why. This qualitative study explored parents' practices and perspectives on seeking health and digital technology use information for their young children.

Objective Measurement of Posture and Movement in Young Children Using Wearable Sensors and Customised Mathematical Approaches: A Systematic Review.

Given the importance of young children's postures and movements to health and development, robust objective measures are required to provide high-quality evidence. This study aimed to systematically review the available evidence for objective measurement of young (0-5 years) children's posture and movement using machine learning and other algorithm methods on accelerometer data. From 1663 papers, a total of 20 papers reporting on 18 studies met the inclusion criteria.

Insomnia and workplace productivity loss among young working adults: a prospective observational study of clinical sleep disorders in a community cohort.

Design, Setting: Prospective, observational study; 22-year follow-up of participants in the longitudinal birth cohort Raine Study (Perth, Western Australia).

Participants: Currently employed 22-year-old Raine Study participants who underwent in-laboratory sleep disorder screening for moderate to severe obstructive sleep apnoea (apnoea-hypopnea index of more than fifteen events/hour or obstructive sleep apnoea syndrome) and were assessed for insomnia and restless legs syndrome using validated measures.

Association between pelvic pain bothersomeness and pain sensitivity: A community-based cross-sectional study of young adult females in the Raine Study.

Objective: Pelvic pain has been associated with augmented nociceptive processing, but large studies controlling for multiple potential confounding factors are lacking. This study investigated the association between pelvic pain bothersomeness and pain sensitivity in young adult women, accounting for potential confounding factors.

Design: Cross-sectional study.

'There's good and bad': parent perspectives on the influence of mobile touch screen device use on prenatal attachment.

The potential for human-computer interaction to have a substantial impact on adults is well documented. However, its potential importance prior to birth has rarely been reported. Parental use of smartphones and tablet computers could influence the relationship between parent and baby during pregnancy (prenatal attachment) and thus child development.

: Parent Perspectives on How the COVID-19 Pandemic Influenced Family Routines, Relationships and Technology Use in Families with Infants.

This study explores how the first wave of the COVID-19 pandemic influenced family routines, relationships and technology use (smartphones and tablet computers) among families with infants. Infancy is known to be an important period for attachment security and future child development, and a time of being susceptible to changes within and outside of the family unit. A qualitative design using convenience sampling was employed.

The association of mobile touch screen device use with parent-child attachment: a systematic review.

Mobile touch screen devices (smartphones and tablet computers) have become an integral part of many parents' and children's lives, with this interaction linked to physical, mental and social outcomes. Despite the known importance of parent-child attachment, evidence on the association between device use and attachment was yet to be reviewed. Following protocol pre-registration, databases were searched, papers screened, and methodological quality assessed.

Patterns of Change in Device-Based Physical Activity and Sedentary Time Following Bariatric Surgery: a Longitudinal Observational Study.

Purpose: The aim of this study is to investigate changes in physical activity (PA) and sedentary time (ST) over 12 months following bariatric surgery.

Methods: Pre-surgery and at 3, 6, 9, and 12 months post-surgery, wearable devices were used to measure PA at different intensities, grouped according to energy expenditure and daily step count, and ST. Measures were also collected of weight and self-efficacy for exercise.

Effectiveness of interventions aiming at reducing sedentary behaviour in a non-surgical population with overweight or obesity: A systematic review and meta-analysis.

Aim: This systematic review and meta-analyses of randomised controlled trials (RCTs) investigated the effectiveness of interventions to reduce sedentary behaviour amongst people with overweight or obesity. Secondarily, it aimed to investigate the effectiveness of these interventions on body mass index (BMI), time spent in moderate-to-vigorous physical activity (MVPA) and health-related quality of life (HRQoL).

Methods: A search of six databases (CENTRAL, PubMed, Embase, PEDro, CINAHL and PsycINFO) was conducted from inception to July 2018.

Do factors related to participation in physical activity change following restrictive bariatric surgery? A qualitative study.

Aims: To explore participants' ability to participate in physical activity (PA), and barriers and facilitators to PA, at 12 months following restrictive bariatric surgery, and how these differed from participants' pre-surgery perceptions. Motivators for PA post-surgery were also explored.

Methods: Qualitative one-on-one in-depth interviews were conducted pre- and 12 months post-surgery.

Beliefs, Barriers and Facilitators to Physical Activity in Bariatric Surgery Candidates.

Background: Bariatric surgery candidates engage in less physical activity (PA) and spend longer periods in sedentary behaviour (SB) when compared to the general adult population. The aim of this study was to explore the beliefs about PA and perceived barriers and facilitators to PA in obese adults scheduled for bariatric surgery.

Methods: Nineteen obese adults (15 females), with a mean (SD) age of 41.

Long-term effects of a program to increase physical activity in smokers.

Background: Programs aimed at increasing physical activity in daily life (PADL) have generated growing interest to prevent the deleterious effects of physical inactivity. Recent literature has shown that a short-term protocol using pedometers increased PADL in smokers with normal lung function. However, the long-term effects of such a protocol were not yet studied.

Reduction of physical activity in daily life and its determinants in smokers without airflow obstruction.

Background And Objective: In smokers without airflow obstruction, detailed, objective and controlled quantification of the level of physical inactivity in daily life has never been performed. This study aimed to objectively assess the level of physical activity in daily life in adult smokers without airflow obstruction in comparison with matched non-smokers, and to investigate the determinants for daily physical activity in smokers.

Methods: Sixty smokers (aged 50 (39-54) years) and 50 non-smokers (aged 48 (40-53) years) matched for gender, age, anthropometric characteristics, educational level, employment status and seasons of the year assessment period were cross-sectionally assessed regarding their daily physical activity with a step counter, besides assessment of lung function, functional exercise capacity, quality of life, anxiety, depression, self-reported comorbidities carbon monoxide level, nicotine dependence and smoking habits.

Comparison of two strategies using pedometers to counteract physical inactivity in smokers.

Introduction: This randomized crossover trial aimed to compare the effects of 2 different protocols using pedometers and informative booklets to increase physical activity in daily life (PADL) in smokers.

Methods: PADL level was assessed at baseline (A1), and subjects were randomly assigned to 2 groups for a month: booklet + pedometer (GB + P; n = 13), which started the protocol receiving a booklet with encouragement to walk as much as possible in everyday life; pedometer + booklet (GP + B; n = 18), which started the protocol wearing a pedometer aiming to achieve 10,000 steps/day. PADL was reassessed (A2), and the interventions were crossed over for 1 month, followed by PADL reassessment (A3).

Short-term effects of using pedometers to increase daily physical activity in smokers: a randomized trial.

Background: In adults it is recommended that the minimum of 10,000 steps/day should be performed in order to consider an individual as active. The pedometer, a small device that counts steps, has been used to monitor and/or motivate physical activity in various populations.

Objective: To investigate the short-term effects of a protocol using a pedometer or an informative booklet to increase daily physical activity in apparently healthy smokers who reached or did not reach the minimum public health recommendation of 10,000 steps/day.

Responsiveness of three instruments to assess self-reported functional status in patients with COPD.

The study aimed to compare the responsiveness of three instruments to assess self-reported changes in functional status after exercise training in patients with COPD: Pulmonary Functional Status and Dyspnea Questionnaire -modified version (PFSDQ-M), London Chest Activity of Daily Living (LCADL) and Medical Research Council scale (MRC). Twenty-two patients (11 female, 66[62-71] years, FEV1 42[33-61]%predicted) participated in a 3-month high-intensity exercise program. The three instruments were applied pre- and post-program, as well as assessment of lung function, muscle strength, exercise capacity (6-minute walking test, 6MWT) and quality of life (St.
