OBJECTIVES: The changes in Washington State and Colorado marijuana laws call for the development of new brief family-focused adolescent marijuana use preventive interventions that are relevant for and tailored to the context of legalization for retail sale. To that end, focus groups with parents and teens were conducted to find out about their concerns and needs in the context of legalization. METHODS: Six semi-structured focus groups (3 with parents, 3 with teens) were conducted in Washington State in 2013 related to consequences of teen marijuana use and messages that would be effective in helping to prevent teens from using marijuana in the context of legal adult use...

OBJECTIVE: Research indicates that intake of sugar-sweetened beverages (SSB) may be associated with negative health consequences. However, differences between assessment methods can affect the comparability of intake data across studies. The current review aimed to identify methods used to assess SSB intake among children and adults in pan-European studies and to inform the development of the DEDIPAC (DEterminants of DIet and Physical Activity) toolbox of methods suitable for use in future European studies...

BACKGROUND: Cardiopulmonary exercise testing is advised ahead of exercise intervention in obese adolescents to assess medical safety of exercise and physical fitness. Optimal validity and reliability of test results are required to identify maximal exercise effort. As fat oxidation during exercise is disturbed in obese individuals, it remains an unresolved methodological issue whether the respiratory gas exchange ratio (RER) is a valid marker for maximal effort during exercise testing in this population...

INTRODUCTION: The Physical Activity Questionnaire for children and adolescents (PAQ-C & PAQ-A) has been widely used in research and field settings. However, there is a lack of information about its final score meaning. OBJECTIVE: To determine PAQ-C and PAQ-A score cut-off values using physical activity (PA) thresholds objectively measured as reference criteria. METHODS: 146 children (n = 83 boys, n = 63 girls) and 234 adolescents (n = 115 boys, n = 119 girls) participated in this study...

BACKGROUND/OBJECTIVES: Breakfast skipping increases during adolescence and is associated with lower levels of physical activity and weight gain. Theory-based interventions promoting breakfast consumption in adolescents report mixed findings, potentially because of limited research identifying which determinants to target. This study aimed to: (i) utilise the Theory of Planned Behaviour (TPB) to identify the relative contribution of attitudes (affective, cognitive and behavioural) to predict intention to eat breakfast and breakfast consumption in adolescents and (ii) determine whether demographic factors moderate the relationship between TPB variables, intention and behaviour...

BACKGROUND: The rapid rise in the global prevalence of obesity suggests that environmental factors may be responsible. The increased use of technology is associated with increased rates of obesity due to declines in physical activity and significant sedentary life style. Internet addiction is also a growing health issue associated with diminished physical activity and poor sleep quality as well as various health problems. The purpose of this study was to determine associations between Internet addiction and adolescent obesity-related problems...

BACKGROUND: The increasing prevalence of childhood obesity is - amongst other factors - due to changed leisure time habits with decreased physical activity and increased media consumption. However, electronic media such as tablets and smartphones might also provide a novel intervention approach to prevent obesity in childhood and adolescence. OBJECTIVES: A summary of interventions applying electronic media to prevent childhood obesity is provided to investigate short term effects as well as long term results of these interventions...

BACKGROUND: Although the relationship of self-efficacy to sports performance is well established, little attention has been paid to self-efficacy in the movements or actions that are required to perform daily activities and prepare the individual to resume sports participation following an injury and associated period of rehabilitation. There are no instruments to measure self-confidence in movement validated in an adolescent population. PURPOSE: The purpose of this paper is to report on the development of the AMCaMP, a self-report measure of confidence in movement and provide some initial evidence to support its use as a measure of confidence in movement...

BACKGROUND: Subacromial space distance and forward head and shoulder posture are common characteristics resulting from swim training. These alterations can cause abnormal scapular kinematics and positioning, potentially increasing compression of structures in the subacromial space and increasing the risk for the development of swimmer's shoulder. PURPOSE: To evaluate the effect of the swim training season on subacromial space distance and forward head and forward shoulder posture as well as to determine the relationship between these variables...

PURPOSE: We aimed to determine if moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) were independently associated with body mass index (BMI) and waist circumference (WC) in children and adolescents. METHODS: Data from the International Children's Accelerometry Database (ICAD) were used to address our objectives (N=11,115; 6-18y; 51% female). We calculated age and gender specific body mass index (BMI) and waist circumference (WC) Z-scores and used accelerometry to estimate MVPA and total SB...

OBJECTIVE: The American Heart Association's (AHA) 2020 Strategic Goals defined a new concept of cardiovascular health (CVH) for adults and children, emphasizing the importance of early prevention of risk factors. CV disease risk factors track from childhood to adulthood, which should be closely monitored over time. However, detailed data on the trends in CVH among children are sparse. Therefore, by adopting the construct from the AHA, the present study seeks to evaluate the changes of ideal CVH, as well as each component, among Chinese children and adolescents in Beijing...

Hypertension is a major health problem in most developed and developing countries. Worldwide, about one billion people were found to have hypertension, and 13% of all deaths were closely related to hypertension. Secular trends in the prevalence of adult hypertension vary by country; some western countries show a decreasing trend for hypertension, while data from some developing countries show increasing prevalence of hypertension. So, it is difficult to predict the future changes in the prevalence of adult hypertension in some countries...

Middle- and low-income countries bear 80 % of the global chronic disease burden. Population-level, multi-sectoral approaches to promoting healthful lifestyles that take into local physical, socioeconomic, and sociocultural characteristics of both the environment and the population are needed. The "Nuestra Voz (Our Voice)" is one such approach that involves neighborhood residents acting as "citizen scientists" to systematically gather information on the barriers and facilitators of physical activity in their neighborhoods and then use their data to collectively advocate for local environmental- and policy-level changes to support active living...

Participation in recreational physical activity is widely acknowledged to provide significant health benefits. Conversely, intense training imposes several constraints, such as intermittent or chronic metabolic and psychogenic training stressors and maintenance of very low body fat to maximize performance. Adolescent and adult athletic women are therefore at risk of overtraining and/or poor dietary intake, which may have several consequences for endocrine function particularly on hypothalamic-pituitary-gonadal axis...
