Filter by:The US Preventive Services Task Force (USPSTF) recommends that providers screen children aged 6 years and older for obesity and offer or refer them to a comprehensive behavioral intervention (≥26 hours over a period of up to 12 months) to promote improvement in weight status. Family-based behavioral treatment (FBT) is an effective treatment that targets both child and parents and meets the USPSTF recommendations. By contrast, the American Medical Association (AMA) recommends a staged approach to childhood obesity screening and counseling, which begins with prevention counseling by the primary care provider (PCP) and includes assessment of weight status, patient/family motivation and readiness to change, promotion of healthy eating and activity habits, and use of health behavior change strategies. Our study compares a staged approach enhanced standard of care (eSOC) vs. eSOC + FBT, to provide families and PCPs with information on the best intervention approach for the behavioral treatment of childhood obesity. Our project seeks to fill the gap in the evidence on family-based weight management in primary care settings among diverse and underserved populations with a special focus on Black children, families insured by Medicaid, and sex differences.
Childhood obesity is increasing with more than one-third of adolescents currently overweight and one in five with obesity. The lifelong incidence of obesity-related morbidities is also increasing with childhood obesity. It is not yet known how obesity develops in an individual, specifically in early childhood. Further, it is unclear what mechanistic role a child's earliest nutrition or changing intestinal flora has in the etiology of obesity. Very young children are developing appetite and satiety patterns early in life. Nutrition and gut microbial flora have impact on how these processes unfold, but specific mechanisms are not yet well understood. The investigators hypothesize that formula-fed infants with changes in their microbial flora are more likely to have altered carbohydrate metabolism, evidenced by greater imbalances of fatty acid production, and are more likely to have accelerated growth trajectory due to satiety disruption. The investigators further hypothesize that altered carbohydrate metabolism, e.g. imbalances of short- and long-chain fatty acid levels in the gut, stimulate cellular stress and affect specific gut hormones. This study will compare the microbiome of the intestinal microbial flora in two groups of infants, one breast fed and the other formula fed, using longitudinally collected fecal samples from both groups. Samples will be subjected to shotgun metagenomic analysis and simultaneous metabolomic analysis. A bioinformatics approach will elucidate key differences among and between sample groups, and will further analyze bacterial gene expression levels related to carbohydrate metabolism. This study will compare the expression of human proteins involved in cellular stress response and gut peptide signaling by applying quantitative Reverse Transcriptase-Polymerase Chain Reaction to human messenger RNA isolated from the longitudinally collected samples from both groups. Finally, this study will monitor the trajectory of growth and feeding over the first 2 years of life. The project's focus on the influence of different early feeding types, microbial flora changes, and altered carbohydrate metabolism leading to disruption of gut-brain signaling will provide critical data for host:microbiome interactions and translational therapeutic targets.
The purpose of this study is to evaluate whether an intervention targeting healthy habit development reduces the risk and prevalence of obesity in low-income mothers and children. The study intends to evaluate whether the intervention, delivered in the context of home visitation services for low-income families, reduces weight gain and risk factors associated with parent and childhood obesity compared to those receiving standard home visitation services.
The QUebec Adipose and Lifestyle InvesTigation in Youth (QUALITY) Cohort study is a unique and comprehensive longitudinal study of 630 Caucasian children and their parents that was designed to investigate the natural history and determinants of childhood obesity and its cardiometabolic consequences.
The purpose of this research is to develop, apply, and evaluate a school-based intervention program in East Jerusalem schools, designed to increase knowledge and to improve the attitudes and healthy behavior of schoolchildren, their teachers and their mothers' with regard to healthy eating and physical activity habits. The study tested the hypothesis that the impact of the entire school intervention program on students' lifestyles is mediated by their teachers' engagement in health promotion and by their mothers' involvement in school activity.
