This pilot study will examine the feasibility, acceptability, and preliminary efficacy of the intervention. This will ensure that all aspects of the research protocol and procedures work as desired and are acceptable to families in preparation for the fully powered randomized controlled trial. The proposed study will assess our ability to: 1)recruit, consent, and retain participants, 2) deliver the intervention, 3) implement study and assessment procedures 4) assess the reliability of the proposed measures in this sample, 5) determine whether modifications to the intervention, procedures, and measures are needed prior to conducting a fully powered study, and 6) willingness of participants to participate in the intervention.
The primary goal of the Connect feasibility trial was to develop and test the feasibility of a physical activity (PA) social-climate-based intervention within pre-existing after school programs (ASPs) that targets youth social goals (e.g., building friendships through PA) and social competencies (e.g., friendship-building skills) to increase the positive PA affect, cognitions, and moderate-to-vigorous (MV) PA of underserved (i.e., low income, minority status) middle school youth. The 8-week intervention was designed to improve several key social mechanisms within ASPs overlooked in previous interventions (e.g., developing friendship and connection to peers and staff through PA; group belonging, including positive peer PA norms and tangible support) that are key predictors of youth PA and included: 1) "Get to know you" sessions aimed at providing youth guided social opportunities to foster friendship-building skills, and to promote acceptance, cooperation, contribution, and friendship affiliation, and; 2) a novel socially-oriented physical activity curriculum tailored to meet the social goals and needs of program staff and participating youth. Comparison of ASPs receiving the 8-week "Connect" intervention (N=3 ASPs) with ASPs randomized to receive the general ASP curriculum (wait-list control condition; N=3 ASPs) will yield preliminary data on the effectiveness of social mediators for improving moderate-to-vigorous physical activity (MVPA) and preventing obesity among at-risk youth that can inform future intervention design and youth programming policy. Results of this proposed project will provide the basis for conducting a large scale efficacy trial. First, it is hypothesized that the Connect program will be documented to be feasible as shown by: 1) youth's greater perceived connectedness and PA affiliation goal orientation from baseline to post-intervention; 2). changes in targeted social climate components from baseline to post-intervention as measured by systematic observations, and; 3) adequate dose and fidelity of program implementation as indicated by weekly process evaluations. Second, it is hypothesized that youth in the social climate program (vs. comparison) demonstrate greater increases in positive PA affect, cognitions, and MVPA from baseline to post-intervention.
The study tested an intervention that used a cue-removal and implementation intentions based strategy to change habitual dietary behaviors. The intervention was evaluated using a randomized experimental design that consisted of two conditions including (1) a control condition or (2) a cue and implementation intention-based intervention. High schools (N=22) were randomly assigned to one of the two conditions. Families (N=187), with a family defined as an adolescent and one participating parent, were recruited from within the 22 schools. All of the families from each school were assigned to the same condition. Families that were eligible for the study and that were interested in participating scheduled an appointment to complete informed consent. After written parental consent and youth assent was obtained, the participants had their height and weight measured and completed a series of questionnaires programmed on laptops. In addition, the adolescent took part in a 24 Hour Dietary Recall Assessment. The family was also informed that a second 24 Hour Dietary Recall Assessment would be administered to the adolescent over the phone in approximately 3-14 days. Families that were from a school assigned to the control condition received an intervention on sun safety that consisted of a 10-minute meeting with a trained Health Coach, two generic newsletters, an email, and a text message. Families from a school assigned to the cue- and implementation intentions condition received an intervention on healthy snacking and the reduction of sugar sweetened beverage consumption that consisted of a 90-minute meeting with a trained Health Coach, two 20-minute phone calls, four tailored newsletters, and a series of emails and text messages. Both of these interventions were delivered over a period of 3-10 weeks depending on the self-directed pace of the participants. All participants were then asked to complete a follow-up assessment appointment three months after their original consenting appointment. Our hypotheses focused on dietary behaviors and stated that adolescents assigned to the cue-removal and implementation intentions intervention would consume significantly fewer daily servings of high fat snacks, high sugar snacks, and sugar sweetened beverages than adolescents in the control condition.
The objectives of this trial are to investigate whether the effects of hemp protein on glycemic and appetite control are insulin-dependent by measuring 1) blood glucose, insulin and appetite for one hour following consumption, 2) blood glucose, insulin and appetite following a fixed energy meal to determine the "second meal effect" of hemp protein versus soybean protein and a non-protein control.
The objectives are to test the acute effects of different extruded pulse snacks on: 1) post-prandial blood glucose, insulin and appetite for two hours, and 2) food intake two hours following consumption of pulse products. The investigators hypothesize that snack products containing pulse ingredients will lead to lower blood glucose, insulin, appetite and food intake responses compared to non-pulse snack products.
The objectives are to test the acute effects of different bagels containing pulse ingredients on: 1) post-prandial blood glucose, insulin and appetite for two hours, and 2) food intake two hours following consumption of pulse products. The investigators hypothesize that bagels containing pulse ingredients will lead to lower blood glucose, insulin, appetite and food intake responses compared to non-pulse bagels.
The objectives are to test the acute effects of different cereals containing pulse ingredients on: 1) aerobic endurance and substrate oxidation during exercise 2) response of blood glucose, insulin and appetite to an aerobic exercise session, and 3) food intake two hours following the exercise session. The investigators hypothesize that consumption of cereals containing pulse ingredients 60 minutes before exercise will increase aerobic endurance (lower oxygen consumption), decrease carbohydrate oxidation (greater respiratory quotient), and a reduction in lactate production during compared to the same exercise session following the ingestion of a non-pulse food. The investigators also hypothesize that consumption of cereals containing pulse ingredients will lead to lower blood glucose, insulin, appetite and food intake, suggesting lower calorie compensation, following a 60-minute aerobic exercise session compared to the same exercise session following the ingestion of a non-pulse food.
The objectives of this trial are to assess the health benefits of acute hemp protein consumption compared to soybean protein and a non-protein control on: 1) blood glucose, appetite and blood pressure for one hour following consumption, 2) food intake at an ad libitum meal one hour following consumption and 3) blood glucose, appetite and blood pressure following the ad libitum meal to determine the "second meal effect" of hemp protein.
The objectives are to test the acute effects of different cereals containing pulse ingredients on: 1) post-prandial blood glucose, insulin and appetite for two hours, and 2) food intake two hours following consumption of pulse products. We hypothesize that cereals containing pulse ingredients will lead to lower blood glucose, insulin, appetite and food intake responses compared to non-pulse cereals.
