Filter by:This study is the second of three sub-studies aimed at evaluating the outcomes of the Living Green and Healthy for Teens (LiGHT) program, delivered through the Aim2Be app (v2.2). Aim2Be is an app for 10 to 17 year olds and their families that is intended to help them shift from an healthy lifestyle toward better health habits in four areas: nutrition, physical activity, recreational screen time, and sleep. This second evaluation has the following aims to: 1) describe reach; 2) assess change in knowledge of Canadian health recommendations; and 3) assess change in lifestyle behaviours and weight outcomes and whether these changes are moderated by involvement in the app. This study uses a two-group parallel/crossover randomized controlled trial design following N=200 families for six months.
This study is the first of three sub-studies aimed at evaluating the outcomes of Living Green, Healthy for Teens (LiGHT v2.1), an app for 13 to 17 year -olds and their families that is intended to help them shift from an unhealthy lifestyle toward better health habits in three areas: physical activity, nutrition and sedentary behaviours. This first evaluation has the following aims to: 1) describe reach; 2) determine utilization/adherence to strategies implemented in the app and predictors of utilization/adherence; 3) assess change in knowledge and lifestyles behaviours associated with obesity as well as assess mediators of behaviour change. As this is a formative evaluation, it will prospectively follow 500 families for 4.5 months.
This study provides a sound basis towards a better understanding of the biochemical mechanisms behind childhood obesity and its metabolic phenotypes, which will be of great importance towards the development of more personalized prevention and treatment in future.
Despite exercise training decrease blood fasting glycemia in 'average' terms, there is a wide interindividual variability after exercise training explored mainly in adults but not in children. Thus, is yet unknown what baseline health status as well as the influence of what health variable may produce more/less non-responder (NR) prevalence (i.e., percentage of subjects who experienced a non-change/worsened response after training in some metabolic outcomes) after exercise training in school children.
Vitamin D deficiency is common in the general population in the United States, but is more common in overweight and obese children. Additionally, vitamin D levels are inversely correlated with body mass index, hypertension, inflammatory markers and insulin resistance. There are currently no clear guidelines regarding vitamin D replacement in obese but otherwise healthy children. The Endocrine Society recommends that children with vitamin D deficiency should take 2000 IU once a day for at least 6 weeks; however, they state that obese children may need 2-3 times this dose in order to reach sufficient levels. The goals of this study are: 1. To determine the prevalence of vitamin D sufficiency (>30 ng/mL), insufficiency (21-29 ng/mL); deficiency (10-19 ng/mL) and severe vitamin D deficiency (<10 ng/dL) in an obese pediatric population (2-11 years) as measured by 25-hydroxyvitamin D. 2. To determine if vitamin D level correlates with percentage body fat by bioelectrical impedance analysis and/or visceral fat by waist circumference in children ages 5 - 11 years. 3. To observe the effect of vitamin D replacement in obese children with vitamin D deficiency using two different replacement dosage levels recommended by the Endocrine Society over three months: 2000 IU once a day (general pediatric dose) vs 6000 IU once a day (suggested obesity dose) in children between the ages of 5 - 11 years. 4. To measure vitamin D levels, bone markers, inflammatory markers and vitamin D binding protein before and after vitamin D supplementation in children between the ages of 5 - 11 years. Analysis will be stratified by degree of obesity (Class I, Class II, Class III) and season.
