Summary
A parent-led physical activity (PA) program improved health-related quality of life (HRQL) in youth with obesity and Prader-Willi syndrome (PWS). Increasing moderate-to-vigorous PA (MVPA) led to reduced body mass and fat while preserving lean mass.
Area of Science:
- Pediatrics
- Obesity Research
- Public Health
Background:
- Childhood obesity and Prader-Willi syndrome (PWS) present significant health challenges.
- Parental involvement in health interventions can be crucial for pediatric outcomes.
- Effective strategies are needed to improve health parameters in youth with obesity and PWS.
Purpose of the Study:
- To determine if a parent-led physical activity (PA) curriculum enhances health markers in obese youth.
- To assess the impact of a PA intervention on body composition, activity levels, and quality of life in youth with obesity and PWS.
Main Methods:
- A prospective study involving 45 youth with PWS and 66 obese youth without PWS.
- Participants were assigned to an intervention (I) or control (C) group, with the I-group engaging in PA sessions 4 days/week for 24 weeks.
- Generalized estimating equations were used to analyze changes in body composition, PA, and health-related quality of life (HRQL).
Main Results:
- Body mass index increased in obese youth but not in those with PWS.
- No significant changes were observed in moderate-to-vigorous PA (MVPA), total PA, or body fat indicators over time.
- The intervention group showed significant improvements in social, school, and total HRQL. Youth in the intervention group who increased MVPA experienced decreased body mass, BMI z-score, and body fat mass.
Conclusions:
- Parent-led home-based PA interventions can positively impact HRQL in youth with obesity and/or PWS.
- Achieving an increase of at least 2 minutes in MVPA was associated with reduced body mass and fat, while maintaining lean mass.
- This suggests that targeted increases in PA, facilitated by parental support, can yield measurable health benefits for at-risk youth.

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

01:27Parenting Styles

Diana Baumrind's four parenting styles — authoritarian, authoritative, neglectful, and permissive — each influence children's socio-emotional development differently.
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.

1.3K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

01:28Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
