Filter by:Research suggests there is a connection between mood and weight. People who feel stressed or depressed are more likely to be overweight than people who don't have these feelings. Some individuals turn to food to cope, which can lead to gaining too much weight over time. Adolescence is an important time to understand these connections. Patterns of handling stress learned during adolescence set the stage for stress management in adulthood. This study is a randomized controlled pilot study with 60 adolescents who are at-risk for future, chronic obesity. The investigators will test if taking part in a 6-week group program to lower stress and improve mood will be helpful to teens at-risk.
Preliminary data from the investigators' National Center for Complementary and Alternative Medicine (NCCAM)-funded R21 on mindfulness-based stress reduction (MBSR) in HIV-infected youth suggest an association between mindfulness and improved self-regulation and medication adherence. This randomized, controlled trial will help the investigators to better understand the specific impact of MBSR on HIV medication and treatment adherence in HIV-infected youth, and the efficacy of MBSR in the amelioration of stress and improved self-regulation.
Background A physically active lifestyle is crucial for development but a large number of youth in Hong Kong are sedentary and do not meet the International (World Health Organisation) and the local (Leisure and Cultural Services Department) recommendation for physical activity. On the other hand, the evidence for implementing positive youth development programme through physical activity and sports is elusive. Purpose This study aimed to promote physical activity and sports amongst adolescents in Hong Kong through a structured sports mentorship intervention. The study also aimed to investigate the effect of such programme in positive youth development. Methods This was a two-phased study with Phase I being the preparatory stage and Phase II being the implementation stage. In Phase I, questionnaire surveys and focus group interviews were conducted to understand the relevant perceptions and opinions amongst various stakeholders (e.g. teachers, parents, and students). The data collected was analysed to inform the design and planning of the Phase II intervention. Phase II was an experimental trial of our sports mentorship programme. Participating students were divided into intervention and control group, where the former received the sports mentorship programme and the later did not. The intervention was 18 weeks long providing an additional 90 minutes of active time per week for all students in the intervention group. Programme mentors were trained and supported in reference to previous evidence. Intervention effectiveness were evaluated by comparing the outcomes between intervention and control group.
This study will evaluate the efficacy of yoga taught during school to positively influence risk and protective factors of substance use and the initiation and severity of substance use. The study hypothesis is that, compared to a control group participating in regular physical education classes, subjects who participate in 32 yoga sessions across an academic year will improve in negative internalizing behaviors and self-regulatory skills that are known risk and protective factors for substance use. This study will also test the hypothesis that the yoga intervention will reduce both severity of substance use and the degree of substance use initiation.
The purpose of this preliminary study is to evaluate the effects of a yoga-based program on high school students' psychological health. Results will be used to generate specific hypotheses of how yoga may improve adolescent mental health.
The Jump-In study will prospectively assess the effects of impact exercise on skeletal development in young girls, including bone mass, bone mineral density, and bone geometry. We hypothesize that girls who regularly participate in impact loading exercise will accrue greater skeletal mass, increase bone density and undergo structural adaptations that in combination will improve bone strength compared to girls who do not participate in impact exercise.
Maximizing calcium retention by the skeleton within the genetic potential is a key strategy to prevent osteoporosis. It has been shown that calcium retention varies between blacks and whites and between gender within race. This study is designed to study the relationship between calcium intakes and calcium retention in Asian adolescent girls and boys. It is hypothesized that calcium intakes which maximize calcium retention will be lower in Asians than for whites studies under the same conditions. In addition it is thought that the differences between races in the physiological mechanisms involved in calcium metabolism will result in a lower calcium intake required to observe a plateau in calcium retention. This is turn could be translated into lower calcium requirements in Asians relative to Caucasians for achieving optimal peak bone mass.
This project supports the post-third-grade assessment of 693 children and their families who were enrolled in a randomized trial of a program of prenatal and infancy home visitation by nurses that was epidemiologically and theoretically grounded. The project will determine whether the beneficial effects of the program on maternal, child, and family functioning extend through the early elementary school years, giving particular attention to maternal life-course and children's emerging antisocial behavior. Assessments of the children will be based on both mother and teacher reports. Teachers are independent, natural raters of the children's adaptation to an important social context. There are numerous reasons to expect that, from a developmental perspective, the effects of the program will increase as children experience the increased academic demands associated with entry into third grade. In addressing these questions, the current study will determine the extent to which this program of prenatal and infancy home visitation by nurses can produce enduring effects on maternal and child functioning (giving particular attention to the prevention of early-onset disruptive behavior disorders) in urban African Americans that are consistent with those achieved with whites in a central New York state county in a separate trial of this program conducted over the past 20 years.
