Collaborative, dyadic, and individual planning and physical activity: A dyadic randomized controlled trial.

Objective: This study was designed to investigate the effects of collaborative, dyadic, and individual planning on moderate-to-vigorous physical activity (MVPA) in target person-partner dyads. Individual planning reflects an "I-for-me" planning of one person's behavior. Collaborative planning refers to joint planning of both dyad members' behavior ("We-for-us" planning), and dyadic planning refers to joint planning of only the target person's behavior ("We-for-me" planning).

Can individual, dyadic, or collaborative planning reduce sedentary behavior? A randomized controlled trial.

Rationale: Although effects of individual planning interventions on physical activity (PA) are well established, less is known about the relationships between planning and sedentary behavior (SB).

Objective: This study evaluated the efficacy of individual planning, dyadic planning (i.e.

Maternal practices and perceptions of child body mass status explain child energy expenditure behaviors and body mass.

This study investigated whether maternal perceptions of child body mass status would predict child body mass index (BMI) z-score via two sets of sequential mediators: (1) four maternal practices promoting child energy expenditure and (2) children's energy expenditure behaviors. The data of N = 729 mother-child dyads were collected at baseline [T1; n = 495 at 7- to 8-month follow-up (T2)]. Mothers reported perceptions of child body mass status and maternal practices (T1); children reported sedentary screen use and physical activity (T1, T2).

Perceptions of Physical Activity Promotion, Transportation Support, Physical Activity, and Body Mass: an Insight into Parent-Child Dyadic Processes.

Background: Socio-ecological models indicate that family, school, and community environment explains children's physical activity and body weight. This study investigated whether parental perceptions of school/community-based physical activity (PA) promotion programs as well as parental and child perceptions of parental instrumental support for child PA (transportation provision) would predict child body weight. Child moderate-to-vigorous physical activity (MVPA) was hypothesized to mediate these associations.

Parental strategies restricting screen use among children, screen home environment, and child screen use as predictors of child body fat: A prospective parent-child study.

Objectives: This study provides an insight into associations between: (1) parental and child perceptions of parental strategies restricting screen use among children, (2) child perceptions of the presence and availability of screen-based equipment at home, (3) child sedentary screen use behaviours, and (4) child body fat.

Design: A prospective study with two assessment periods (Time 1, T1; Time 2, T2), spanning 7-8 months.

Methods: At T1, 879 parent-child dyads (83.

From enjoyment to physical activity or from physical activity to enjoyment? Longitudinal associations in parent-child dyads.

Background: This longitudinal dyadic study used cross-lagged analyses to examine reciprocal patterns of associations between physical activity (PA) enjoyment and moderate-to-vigorous PA (MVPA) among children and their parents.

Methods: At Time 1 (T1) 879 parent-child dyads provided their data. The follow-up (Time 2, T2) took place 7-8-months later.

Gender-Specific Body Areas Satisfaction and Body Weight Status in Adolescents: Mediating Effects of Physical Activity, Fruit and Vegetable Intake, and Energy-Dense Food Intake.

Background: Body satisfaction is one of the key modifiable cognitive determinants of eating behaviours, physical activity, and body mass index (BMI). As the sociocultural models suggest, low body satisfaction may explain unhealthy eating and exercise behaviours. Importantly, body satisfaction levels and body areas that individuals focus on vary across genders.

Body satisfaction and body weight in under- and healthy-weight adolescents: mediating effects of restrictive dieting, healthy and unhealthy food intake.

Purpose: Theoretical models, such as the transdiagnostic model of eating disorders highlight the role of cognitive factors (e.g., the way people perceive their bodies) and their associations with maladaptive weight management behaviors resulting in underweight.

Mental Strategies Predict Performance and Satisfaction with Performance among Soccer Players.

This study investigated the changes in mental strategies across the season and their effects on performance and satisfaction with individual performance. Data were collected three times: at the pre-season at Time 1 (T1; baseline), in the mid-season at Time 2 (T2; two-month follow-up), and at the end-of-season at Time 3 (T3; nine-month follow-up) among male soccer players (N = 97) aged 16-27. Athletes completed the questionnaires assessing the use of nine psychological strategies in competition and the level of satisfaction with individual performance.

Sedentary behaviours and health-related quality of life. A systematic review and meta-analysis.

Researchers have speculated that sedentary behaviour may reduce health-related quality of life (HRQOL), but the extent to which this is true remains unknown. Our study sought to systematically review and synthesise research on the relationship between sedentary behaviours and HRQOL and to investigate if these relationships are moderated by age, health status, and HRQOL domain. The review was registered with PROSPERO (no.

A vicious cycle among cognitions and behaviors enhancing risk for eating disorders.

Background: Establishing the sequence in which risk factors for eating disorders (ED) emerge would enable more effective ED prevention. Thus, in our study we investigated reciprocal and indirect associations between three cognitive and behavioral ED determinants (appearance orientation, appearance worries, and dieting) emphasized in the transdiagnostic model of ED.

Methods: Data were collected in a non-clinical group of adolescents at Time 1 (T1), and then 2-months (Time 2, T2) and 13-months later (Time 3, T3).

Immobilization of selected heavy metals in sewage sludge by natural zeolites.

This contribution presents the possibility of application of natural sorbent (Transcarpathian clinoptylolite (KL)) for immobilization of selected heavy metals in the sewage sludge. The influence of ion-exchange parameters (e.g.
