Description
While obesity rates have plateaued within the last decade,
two-thirds of the United States
population is currently classified as overweight (defined a
s a body mass index [BMI] of
25-29.9 kg/m²) or obese (a BMI greater than 30 kg/m²). Bariatric
surgical interventions
are not only more effective than behavioral treatments
in the short term but are the only
form of obesity intervention with evidence of consisten
t long-term effectiveness.
However, even among bariatric surgery patients, weight
loss often stabilizes and it is
estimated that more than 20% of bariatric surgery patient
s will regain a significant
amount of weight that was initially lost long-term. Li
ttle research to date has been
conducted on physical activity in post bariatric surgery pati
ents. More specifically, there
have been no studies to date examining the effects of Me
ditative Movement (MM)
programs on body composition in bariatric patients. A s
tudy using an 8-week Tai Chi
Easy program was conducted in female gastric bypass patient
s to explore feasibility of
MM in the bariatric population as well as pre- and post-in
tervention changes in weight,
mindfulness, eating behaviors, body awareness, physical a
ctivity patterns, dietary quality
and mood. Data analysis revealed that there were no s
ignificant changes in weight or
physical activity patterns; however, significant changes w
ere observed in anxiety, overall
body awareness and cognitive restraint in eating. Addit
ionally, a significant decrease in
processed meat consumption and a weak trend towards increa
sed consumption of fruits
may suggest an overall improvement in dietary quality.

Description
Introduction: Several faith-based or faith-placed programs have focused on the physical dimension of wellness in efforts to improve health by increasing physical activity and improving diet behaviors. However, these programs were not designed to intervene on the mental dimension of wellness which is critical for stress reduction and health behavior change. Purpose: To evaluate the feasibility of a spirituality-based stress reduction and health behavior change intervention using the Spiritual Framework of Coping (SFC) model. Methods: This study was a quasi-experimental one group pretest posttest design. The study was a total of eight weeks conducted at a non-denominational Christian church. Participants were recruited from the church through announcements and flyers. The Optimal Health program met once a week for 1.5 hours with weekly phone calls during an additional four week follow-up period. Feasibility was assessed by the acceptability, demand, implementation, practicality, integration, and limited efficacy of the program. Analysis: Frequencies for demographics were assessed. Statistical analyses of feasibility objectives were assessed by frequencies and distribution of responses to feasibility evaluations. Limited efficacy of pretest and posttest measures were conducted using paired t-test (p <.05). Results: The Optimal Health Program was positively accepted by participants. The demand for the program was shown with average attendance of 78.7%. The program was successfully implemented as shown by meeting session objectives and 88% homework completion. The program was both practical for the intended participants and was successfully integrated within the existing environment. Limited efficacy changes within the program were mostly non-significant. Conclusion: This study tested the feasibility of implementing the Optimal Health program that specifically targeted the structural components of the Spiritual Framework of Coping Model identified to create meaning making and enhance well-being. This program may ultimately be used to help individuals improve and balance the spiritual, mental, and physical dimensions of wellness. However, length of study and limited efficacy measures will need to be reevaluated for program success.

Description
An increasingly sedentary population in the United States, specifically with adolescents, is putting youth at risk of future health related trauma and disease. This single-case design study, Walking Intervention Through Text Messaging for Adolescents (WalkIT-A), was used to intervene with a 12-year old, physically inactive male, in an attempt to test the efficacy of a 12-week physical activity program that may help reduce health risks by increasing number of steps walked per day. The components of the intervention consisted of a FitBit Zip pedometer, physical activity education, text messages, monetary incentives, and goal setting that adapted personally to the participant. Mean step count increased by 30% from baseline (mean = 3603 [sd = 1983]) to intervention (mean = 4693 [sd = 2112]); then increased slightly by 6.7% from intervention to withdrawal (mean = 5009 [sd = 2152]). Mean "very active minutes" increased by 45% from baseline (mean = 8.8 [sd = 8.9]) to intervention (mean = 12.8 [sd = 9.6]); then increased by 61.7% from intervention to withdrawal (mean = 20.7 [sd = 8.4]). Weight, BMI, and blood pressure all increased modestly from pre to post. Cardiovascular fitness (estimated VO2 max) improved by 12.5% from pre (25.5ml*kg-1*min-1) to post (28.7ml*kg-1*min-1). The intervention appeared to have a delayed and residual effect on the participant's daily steps and very active minutes. Although the idealistic ABA pattern did not occur, and the participant did not meet the target of 11,500 daily steps, a positive trend toward that target behavior in the latter 1/3rd of the intervention was observed. Results suggest the need for an extended intervention over a longer period of time and customized even further to the participant.

Description
Physical activity, sedentary behaviors, and sleep are often associated with cardiometabolic biomarkers commonly found in metabolic syndrome. These relationships are well studied, and yet there are still questions on how each activity may affect cardiometabolic biomarkers. The objective of this study was to examine data from the BeWell24 studies to evaluate the relationship between objectively measured physical activity and sedentary behaviors and cardiometabolic biomarkers in middle age adults, while also determining if sleep quality and duration mediates this relationship. A group of inactive participants (N = 29, age = 52.1 ± 8.1 years, 38% female) with increased risk for cardiometabolic disease were recruited to participate in BeWell24, a trial testing the impact of a lifestyle-based, multicomponent smartphone application targeting sleep, sedentary, and more active behaviors. During baseline, interim (4 weeks), and posttest visits (8 weeks), biomarker measurements were collected for weight (kg), waist circumference (cm), glucose (mg/dl), insulin (uU/ml), lipids (mg/dl), diastolic and systolic blood pressures (mm Hg), and C reactive protein (mg/L). Participants wore validated wrist and thigh sensors for one week intervals at each time point to measure sedentary behavior, physical activity, and sleep outcomes. Long bouts of sitting time (>30 min) significantly affected triglycerides (beta = .15 (±.07), p<.03); however, no significant mediation effects for sleep quality or duration were present. No other direct effects were observed between physical activity measurements and cardiometabolic biomarkers. The findings of this study suggest that reductions in long bouts of sitting time may support reductions in triglycerides, yet these effects were not mediated by sleep-related improvements.

Description
"Globesity," as defined by the World Health Organization, describes obesity as a pandemic affecting at least 400 million people worldwide. The prevalence of obesity is higher among women than men; and in non-Hispanic black and Hispanic populations. Obesity has been significantly associated with increased all-cause mortality, and mortality from cardiovascular disease, obesity-related cancers, diabetes and kidney disease. Current strategies to curb obesity rates often use an ecological approach, suggesting three main factors: biological, behavioral, and environmental. This approach was used to develop four studies of obesity. The first study assessed dietary quality, using the Healthy Eating Index (HEI)-2005, among premenopausal Hispanic and non-Hispanic white women, and found that Hispanic women had lower total HEI-2005 scores, and lower scores for total vegetables, dark green and orange vegetables and legumes, and sodium. Markers of obesity were negatively correlated with total HEI-2005 scores. The second study examined the relationship between reported screen time and markers of obesity among premenopausal women and found that total screen time, TV, and computer use were positively associated with markers of obesity. Waist/height ratio, fat mass index, and leptin concentrations were significantly lower among those who reported the lowest screen time versus the moderate and high screen time categories. The third study examined the relationship between screen time and dietary intake and found no significant differences in absolute dietary intake by screen time category. The fourth study was designed to test a brief face-to-face healthy shopping intervention to determine whether food purchases of participants who received the intervention differed from those in the control group; and whether purchases differed by socioeconomic position. Participants in the intervention group purchased more servings of fruit when compared to the control group. High-income participants purchased more servings of dark green/deep yellow vegetables compared to those in the low-income group. Among those who received the intervention, low-income participants purchased foods of lower energy density, and middle-income participants purchased food of higher fat density. The findings of these studies support policy changes to address increasing access and availability of fruits and vegetables, and support guidelines to limit screen time among adults.

Description
Obesity rates among adults have steadily grown in recent decades all the way up to 42.4% in 2018. This is a 12% increase from the turn of the century (Center for Disease Control and Prevention, 2021). A major reason for this rise is increased consumption of processed, high-calorie foods. People eat these foods at a young age and develop bad eating habits that can last for the rest of their lives. It is essential to intervene early and help adolescents form balanced, healthy eating habits before bad habits are already formed. Our solution to this problem is Green Gamers. Green Gamers combines adolescent’s passion for gaming with healthy eating via in-game rewards for healthy eating. People will be able to purchase healthy food items, such as a bag of carrots, and on the packaging there will be a QR code. They will then be able to scan the code on our website, and earn points which will unlock in-game items and other rewards. Video game rewards act as effective motivators for you people to eat more healthy foods. After the solution was formulated, a preliminary survey was conducted to confirm that video game related rewards would inspire children to eat more healthy foods. Based on those results, we are currently in the process of running a secondary market research campaign to learn if gift card rewards are a stronger motivator. Our end goal for Green Gamers would be to partner with large gaming studios and food producers. This would allow us access to many gaming franchises, so that rewards are available from a wide variety of games: making the platform appealing to a diverse audience of gamers. Similarly, a relationship with large food producers would give us the ability to place QR codes on a greater assortment of healthy food items. Although no relationships with large companies have been forged yet, we plan to utilize funding to test our concept on small focus groups in schools.
