Transformative Insights: Break Up with Salt (BUWS) Program's Short-Term Influence on Hypertension Risk Factors.

Break Up with Salt (BUWS) is a four-session community-based nutrition education program aimed at reducing key controllable hypertension risk factors. This pilot study utilized a pre-post survey design to assess short-term outcomes on food behaviors (including DASH diet eating patterns), physical activity, and overall well-being, in two groups of participants. The first "pilot" group (n = 25) completed a comprehensive, 16-item survey; the second "abbreviated" group (n = 27) completed a 5-item survey. The pilot group experienced improvements in whole grain (p = 0.04), sweetened beverage consumption, watching/reducing sodium (p = 0.04) and fat (p = 0.05) consumption, and time spent sitting (p = 0.04). The abbreviated group improved confidence in using food labels (p = 0.02), following the DASH diet (p < 0.01), preparing food without salt (p = 0.03), selecting lower sodium items when eating out (p = 0.04), and making a positive lifestyle change (p = 0.01). The BUWS program provides information and teaches strategies to manage or prevent hypertension. By effectively improving diet and food behaviors, BUWS has the potential to reduce hypertension risk factors and improve the general health of participants.

Factors that predict weight loss success differ by diet intervention type.

Background: Many types of diet intervention can achieve negative energy balance and successful weight loss in persons with obesity. However, within any dietary strategy, there is large inter-individual variation in the weight loss response. The aim of this study is to determine factors that predict weight loss success for diet interventions that vary by macronutrient and caloric composition. Methods: Participants with BMI 30.0 to 49.9 kg/m2 self-selected one of three diet intervention trials for weight loss: low carbohydrate (LOW CHO), low fat (LOW FAT), or low calorie (LOW KCAL). Multivariable regression models were developed to determine the significance of predictor demographic, body composition, metabolic, clinical, and dietary variables for each diet type. Results: Weight loss over 12-16 weeks averaging -5.1 ± 4.0 kg from baseline weight, p < 0.001, was not significantly different among diet types. Several different factors were identified that account for the inter-individual variance in weight loss success. Regardless of diet type, the most robust predictor of weight loss success was completion of the intervention, accounting for 20-30% of the variance. Factors predicting diet intervention completion were age, physical activity level, blood leptin level, blood pressure, and the amount of weight loss occurring. Differences by diet type in cardiometabolic risk factor reduction were identified with LOW CHO decreasing glycemia/insulinemia factors, LOW FAT decreasing lipidemia factors, and LOW KCAL decreasing inflammatory factors. Conclusion: These data provide evidence to inform more precise and personalized approaches to diet intervention for weight loss and cardiometabolic health.

Preliminary Validation of Digital Photography to Assess the Home Food Environment.

The home food environment (HFE), the availability and accessibility of foods and food products within the home, has a strong influence on healthy eating behaviors. Studies assessing the HFE commonly utilize a home food inventory (HFI) for data collection. However, this approach tends to be burdensome for participants. This study validated a low-burden digital photo method for assessing the home food environment and confirmed that this method is preferred by participants. Study participants completed an HFI, submitted photos of household foods, then identified preference for the HFI or photo reporting method. Researchers completed an HFI based on each participant's photo submissions. Researcher-to-participant and researcher-to-researcher comparisons were made through ANOVA and randomized block analyses to determine concurrent validity and inter-rater reliability. Method preference was assessed using the Z-test. The participant group (N = 53) was predominantly female (68%), young adult (90.5%), and Hispanic or Latino (71.7%). Concurrent validity was initially moderate (ĸ = 0.54); adjustments yielded substantial agreement (ĸ = 0.61). The inter-rater reliability (p = 0.98) demonstrated significant consistency among reviewers. The photo-documentation method was found to be valid and preferred (p = 0.01) for reporting on the HFE. The photo method can be used advantageously to collect quality data.

Snacking Consumption among Adults in the United States: A Scoping Review.

Snacks are a staple of the American diet, contributing to approximately 20% of energy intake. Most U.S. adults consume one to three snacks/day, yet few reviews have focused on snacking among this population. This scoping review was conducted to characterize snacks and snacking occasions among U.S. adults to further inform healthy eating practices. The protocol was prepared following the PRISMA-Extension for Scoping Reviews. Three web databases were used to identify articles using snacking or eating occasions as primary or secondary outcomes among U.S. adults. A search strategy was developed using subject headings, truncation, and phrase searching in the title and abstract of articles published between 2010 and 2022. A two-stage, multi-step screening process identified 31 of 4795 publications as meeting the inclusion criteria. Findings included identification of snacking themes, e.g., cues and motivations; diet composition; and weight management. Food quality, time of consumption, and convenience emerged as characteristics of snacking; time of day was found to influence food choice. Snacks contribute to or detract from a healthy diet. Strategic selection of healthy snack options can improve diet quality. Applied to nutrition education, this information can help strengthen programs or policies, ultimately contributing to health and wellbeing.

Evaluation of the Small Changes, Healthy Habits Pilot Program: Its Influence on Healthy Eating and Physical Activity Behaviors of Adults in Louisiana.

The community-based Small Changes, Healthy Habits (SCHH) program was developed to teach skills and techniques to help adults in Louisiana make and maintain small behavioral changes in their food selection, preparation, and consumption, and in physical activity routines. The content of this four-week program included habit formation and goal setting techniques; physical activity guidance; strategies for a healthier home food environment; a grocery store tour focused on label reading for healthier food selections; basic knife and cooking skills. The program was piloted at ten sites throughout the state. A survey with 14 core items was applied before and after the program to evaluate participant acquisition of skills and behaviors associated with topic areas. A total of 47 participants provided complete data sets. Post-program, these participants reported increased confidence in preparing healthy meals at home (p = 0.04); changes in fats (p = 0.03) and salt (p = 0.01) intake; increased frequency of reading nutrition labels (32%); decreased frequency of meals eaten outside the home (Improvement Index = 0.27); and decreased time/day spent sitting (p < 0.05). These short-term results suggest that the SCHH program has potential to positively affect healthy eating and to reduce sedentary behaviors, both of which are fundamental to good health and wellness.

Improving Health Behaviors Through Community Engagement: Challenge for a Healthier Louisiana.

There is increasing recognition that community-based approaches may have merit in improving physical activity and healthy eating behaviors. The "Challenge for a Healthier Louisiana" program supported twelve projects that addressed the root causes of obesity through integrated community-level changes. Partnerships provided community-based obesity prevention by promoting healthier eating and/or physical activity through enhanced infrastructure, policy changes, and programming. To evaluate whether the program resulted in changes in healthy eating and/or physical activity among adults, surveys were conducted pre- and postintervention among participants. Participants who were exposed to physical activity programs were more likely to adopt the consumption of fruits (odds ratio = 2.0; 95% confidence interval [1.1, 3.6]), were more likely to eat vegetables once per day (p = .028), and were more likely to participate in physical activity (p = .053). Participants who were exposed to healthy eating programs were more likely to eat fruit once per day (p = .035), were more likely to eat vegetables at least once per day (p = .008), and were more likely to participate in physical activity (p = .018). In conclusion, there is some indication that the Challenge for a Healthier Louisiana program produced changes in health behaviors among program participants; however, the sustainability of these changes will require further evaluation.

Engaging communities to develop and sustain comprehensive wellness policies: Louisiana's schools putting prevention to work.

BACKGROUND: Tobacco use, obesity, and physical inactivity among Louisiana's youth pose a serious public health problem. Given the potential of school environments to affect student well-being, the Louisiana Tobacco Control Program developed and tested a pilot program, Schools Putting Prevention to Work. The objective was to assist school districts in developing a comprehensive school wellness policy and engaging their school community to generate environments that support healthful choices and behaviors. COMMUNITY CONTEXT: The pilot was implemented in 27 school districts, reaching an estimated 325,000 people across the state. Demographics of participating students were similar to all Louisiana's public school students. METHODS: A school wellness project state team advised project development. A subgroup that included contractors and partners implemented and modified the pilot. Sites were selected though an application process. Site representatives received trainings, technical assistance, and funding to organize school-based support-building activities and coordinate a school health advisory council to develop policy and sustain healthy school environments. Project sites reported progress monthly; evaluation included data from sites and project administrators. OUTCOME: Twenty-five comprehensive school wellness policies (covering 100% tobacco-free schools and daily physical activity and healthier cafeteria items) were approved by school boards. Environmental changes such as physical activity breaks, healthier vending options, and tobacco-free campuses were adopted. INTERPRETATION: This pilot demonstrated a successful approach to achieving policy and environmental change. The state team engaged and guided school districts to motivate students, parents, faculty/staff/administration, and businesses to establish and maintain opportunities to improve lifestyle health.

Is the fructose index more relevant with regards to cardiovascular disease than the glycemic index?

The glycemic index (G.I.) is a means for categorizing carbohydrates based on their ability to raise blood glucose, subsequently this index has been popularized as a way for selecting foods to reduce the risk for obesity, diabetes, and cardiovascular disease. We suggest that the G.I. is better aimed at identifying foods that stimulate insulin secretion rather than foods that stimulate insulin resistance. In this regard, fructose has a low G.I. but may be causally linked with the obesity and cardiovascular disease epidemic. The reported association of high G.I. with cardiovascular disease may be due to the association of sugar intake which contains fructose, but which has a high G.I. due to its glucose content. We propose the use of a fructose index to categorize foods and propose studies to determine the effect of low fructose diets as a means to prevent obesity, diabetes, and cardiovascular disease in the population.

Improvements in nutritional intake and quality of life among frail homebound older adults receiving home-delivered breakfast and lunch.

OBJECTIVE: This study evaluated the influence that expanding a home-delivered meals service to include breakfast and lunch would have on the nutritional status and quality of life of at-risk older adults. DESIGN: This cross-sectional field study compared two groups. The breakfast group (n=167) received a home-delivered breakfast and lunch, 5 days per week. The comparison group (n=214) received a home-delivered lunch 5 days per week. Participants' 24-hour food recall, demographics, malnutrition risk, functional status, and surveys of quality of life as health, loneliness, food enjoyment, food security, and depression were obtained. PARTICIPANTS: Study participants were recruited from five Elderly Nutrition Programs involved in the Morning Meals on Wheels breakfast service demonstration project. They formed a geographically and racially/ethnically diverse sample. Participants ranged in age from 60 to 100 years, were functionally limited, and at high nutritional risk. Most were low income, lived alone, and had difficulty shopping or preparing food. STATISTICAL ANALYSIS: Descriptive statistics were used to assess group comparability. Independent sample t tests were used to examine group differences, with Bonferroni's method used to control for familywise Type I error. RESULTS: Breakfast group participants had greater energy/nutrient intakes (P<.05), greater levels of food security (P<.05), and fewer depressive symptoms (P<.05) than comparison group participants. CONCLUSIONS: The addition of a breakfast service to traditional home-delivered meals services can improve the lives of frail, homebound older adults. Agencies should be encouraged to expand meals programs to include a breakfast service to a targeted population.
