Veterinary-prescribed physical activity promotes walking in healthy dogs and people.

BACKGROUND: Regular physical activity (PA) promotes health and can prevent and treat diseases among both humans and dogs. Unfortunately, most U.S. adults do not meet PA recommendations, and many dogs are also insufficiently active. Veterinary-prescribed PA programs have shown some success in increasing activity among overweight dogs, but the impacts of such programs have not yet been tested for efficacy among otherwise-healthy dogs and owners. In addition, although wearable devices that monitor PA and provide individuals with feedback (e.g., progress toward a daily step goal) can effectively increase human PA, it is unclear what impact similar wearable devices have on human and dog PA when the PA-monitoring devices are worn by dogs. The present study assessed the impact of an 8-week veterinary-prescribed PA program on activity and health among dogs and their owners, and randomized participants (n = 59) to two groups: one in which PA was measured but not visible to participants (n = 30), and one in which PA was measured and real time feedback was visible through a wearable device (n = 29). RESULTS: Participants in both groups showed significant PA increases over the course of the 8-week program. Biomedical testing performed at the veterinary clinic facilitated early diagnosis of systemic illness in one human participant. The frequency of hypertension in human participants decreased significantly from baseline to the end of the program (week 8). Other health indices (e.g., BMI in humans, body weight and BCS in dogs) improved, albeit not to a statistically significant extent, over the course of the program. There were no significant differences on the outcomes of interest between the two experimental conditions. CONCLUSIONS: Veterinary-prescribed PA programs appear promising for increasing PA among insufficiently active but otherwise healthy dogs as well as their owners. Additional testing of veterinary-prescribed PA is warranted, particularly at other types of veterinary clinics (e.g., private practices). Incorporating wearable devices permitting owners to track canine PA did not appear necessary for obtaining these benefits; however, additional studies investigating alternative devices or different time periods may be warranted.

Comparing five front-of-pack nutrition labels' influence on consumers' perceptions and purchase intentions.

In 2011, a National Academy of Medicine report recommended that packaged food in the U.S. display a uniform front-of-package nutrition label, using a system such as a 0-3 star ranking. Few studies have directly compared this to other labels to determine which best informs consumers and encourages healthier purchases. In 2013, we randomized adult participants (N=1247) in an Internet-based survey to one of six conditions: no label control; single traffic light; multiple traffic light; Facts Up Front; NuVal; or 0-3 star ranking. We compared groups on purchase intentions and accuracy of participants' interpretation of food labels. There were no differences in the nutritional quality of hypothetical shopping baskets across conditions (p=0.845). All labels improved consumers' abilities to judge the nutritional quality of foods relative to no label, but the best designs varied by outcomes. NuVal and multiple traffic light labels led to the greatest accuracy identifying the healthier of two products (p<0.001), while the multiple traffic light also led to the most accurate estimates of saturated fat, sugar, and sodium (p<0.001). The single traffic light outperformed other labels when participants compared nutrient levels between similar products (p<0.03). Single/multiple traffic light and Facts Up Front labels led to the most accurate calories per serving estimations (p<0.001). Although front-of-package labels helped participants more accurately assess products' nutrition information relative to no label, no conditions shifted adults' purchase intentions. Results did not point to a clearly superior label design, but they suggest that a 3-star label might not be best for educating consumers.

Comparison of two front-of-package nutrition labeling schemes, and their explanation, on consumers' perception of product healthfulness and food choice.

OBJECTIVE: Front-of-package (FOP) nutrition labels are increasingly used to present nutritional information to consumers. A variety of FOP nutrition schemes exist for presenting condensed nutrition information. The present study directly compared two symbolic FOP labeling systems - traffic light and star-based schemes - with specific regard to healthfulness perception and purchase intention for a variety of products. Additionally, this study investigated which method of message framing (gain, loss, gain + loss) would best enable individuals to effectively utilize the FOP labels. METHOD: College students (n = 306) viewed food packages featuring either star or traffic light FOP labels and rated the healthfulness of each product and their likelihood of purchasing the product. Within each label type, participants were presented with differently-framed instructions regarding how to use the labels. RESULTS: Participants who viewed the star labels rated products with the lowest healthfulness as significantly less healthful and rated products with the highest healthfulness as significantly more healthful compared to participants who viewed those same products with traffic light labels. Purchase intention did not differ by label type. Additionally, including any type of framing (gain, loss, or gain + loss) assisted consumers in differentiating between foods with mid-range vs. low nutritional value. CONCLUSIONS: Star-based labels led more healthful foods to be seen as even more healthful and less healthful foods to be seen as even less healthful compared to the same foods with traffic light labels. Additionally, results indicate a benefit of including framing information for FOP nutrition label instructions; however, no individual frame led to significantly different behavior compared to the other frames. While ratings of product healthfulness were influenced by the framing and the label type, purchase intention was not impacted by either of these factors.

Impact of explained v. unexplained front-of-package nutrition labels on parent and child food choices: a randomized trial.

OBJECTIVE: The present study investigated whether parent/child pairs would select more healthful foods when: (i) products were labelled with front-of-package (FOP) nutrition labels relative to packages without labels; (ii) products were labelled with colour-coded Multiple Traffic Light (MTL) FOP labels relative to monochromatic Facts up Front (FuF) FOP labels; and (iii) FOP labels were explained via in-aisle signage v. unexplained. DESIGN: Participants were randomly assigned to one of five conditions: (i) FuF labels with in-aisle signs explaining the labels; (ii) FuF labels, no signage; (iii) MTL labels with in-aisle signage; (iv) MTL labels, no signage; (v) control group, no labels/signage. Saturated fat, sodium, sugar and energy (calorie) content were compared across conditions. SETTING: The study took place in a laboratory grocery aisle. SUBJECTS: Parent/child pairs (n 153) completed the study. RESULTS: Results did not support the hypothesis that MTL labels would lead to more healthful choices than FuF labels. The presence of FOP labels did little to improve the healthfulness of selected foods, with few exceptions (participants with v. without access to FOP labels selected lower-calorie cereals, participants with access to both FOP labels and in-aisle explanatory signage selected products with less saturated fat v. participants without explanatory signage). CONCLUSIONS: Neither MTL nor FuF FOP labels led to food choices with significantly lower saturated fat, sodium or sugar. In-aisle signs explaining the FOP labels were somewhat helpful to consumers in making more healthful dietary decisions. New FOP labelling programmes could benefit from campaigns to increase consumer awareness and understanding of the labels.

General and food-selection specific parenting style in relation to the healthfulness of parent-child choices while grocery shopping.

Past research has demonstrated that parenting style is related to children's health and eating patterns, and that parenting can vary across time and context. However, there is little evidence about similarities and differences between general, self-reported parenting style and observed parenting during grocery shopping. The goals of this study were to investigate links between general parenting style, parental warmth and limit setting (important dimensions of parenting style) during grocery shopping, and the healthfulness of foods chosen. Participants were 153 parent (88 mothers) - child (6-9 years old) dyads. Dyads were brought to a laboratory set up like a grocery store aisle and asked to choose two items from each of three categories (cookies/crackers, cereals, chips/snacks). Parents were observed in terms of warmth, responsiveness, autonomy granting, and limit setting; children were observed in terms of resistance and negotiation. Parents reported behaviors related to general parenting. Regression analyses were used to test study hypotheses. Observed parental limit setting was related to general parenting style; observed warmth was not. Observed limit setting (but not observed warmth or self-reported parenting style) was related to the healthfulness of food choices. Limit setting appears to be the dimension of parenting style that is expressed during grocery shopping, and that promotes healthier food choices. Implications are discussed regarding consistencies in parenting style across situations as well as contributions of parenting style to the development of children's healthy eating.

Simplifying mental math: Changing how added sugars are displayed on the nutrition facts label can improve consumer understanding.

BACKGROUND: Proposed variations to Nutrition Facts Labels (NFL) have included the display of added sugars (AS) content, but its impact on consumer understanding is poorly understood. OBJECTIVE: To examine the degree to which different formats for displaying AS influence consumer understanding, perceptions, and purchase intentions. DESIGN: Randomized-controlled online experiment. PARTICIPANTS: A sample of 2509 U.S adults. INTERVENTION: Participants were randomized to 1 of 8 conditions and viewed 10 food or beverage images with either: (1) no label (control); (2) the current NFL (without AS); (3) the proposed NFL without AS; or the proposed NFL with AS in (4) grams, (5) grams and teaspoons, (6) grams and percent Daily Value (%DV), (7) grams with high/medium/low text, or (8) grams with high/medium/low text and %DV. MAIN OUTCOME MEASURES & STATISTICAL ANALYSIS: ANCOVAs compared scores on quizzes that assessed the accuracy of judgments about AS, overall nutrition understanding and purchase intentions. RESULTS: Presenting AS in grams plus high/medium/low text with and without %DV led to the highest AS understanding scores (85% and 83% correct, respectively) compared to 70% correct when AS was not on the label or was displayed in grams only (74% correct). Displaying AS in teaspoons did not significantly improve understanding beyond grams alone. Consumers were best able to determine which of two products was healthier when AS was presented as %DV (68% correct) versus displayed in grams alone (60% correct), but %DV did not differ from high/medium/low text or teaspoons. None of the labels influenced purchase intentions relative to no label. CONCLUSION: Displaying AS on the NFL in grams with high/medium/low text, %DV, or the combination of the two, improved consumer understanding more than presenting it in grams or teaspoons.

The Associations of Eating-related Attitudinal Balance with Psychological Well-being and Eating Behaviors.

This study used balance theory to illuminate the relations of eating-related attitudinal consistency between self and friends to psychological well-being and eating behaviors. It was hypothesized that attitudinal inconsistency, relative to consistency, would predict lower well-being and poorer eating habits. A population-based sample of 2287 young adults participating in Project EAT-III (Eating Among Teens and Young Adults) completed measures of psychological well-being, eating behaviors, and eating-related attitudes from the standpoint of self and friends. Of participants who cared about healthy eating, those who perceived that their friends did not care about healthy eating had lower well-being and less-healthy eating behaviors (fewer fruits and vegetables and more sugary beverages per day) than those who perceived that their friends cared about healthy eating. Conversely, among participants who did not care about healthy eating, those who perceived that their friends cared about healthy eating had lower well-being and less-healthy eating behaviors (more snacks per day) than those who perceived that their friends did not care about healthy eating. In accord with balance theory, young adults who perceived inconsistent eating attitudes between themselves and their friends had lower psychological well-being and generally less-healthy eating behaviors than people who perceived consistent eating attitudes.

Environmental modifications and 2-year measured and self-reported stair-use: a worksite randomized trial.

Environmental modifications have been shown to increase short-term stair use, longer-term success is unclear. This study assessed the 2-year effectiveness of an environmental intervention promoting worksite stair use. We assessed stair use at work by means of self-reports and infrared beam counters (which send a safe and invisible beam of infrared light from one side of a stairwell to a reflector on the other side; when an individual uses the stairs, the infrared beam is disrupted and an instance of stair use is recorded) at six worksites (three intervention, three control) in a group randomized, controlled worksite weight-gain prevention trial in Minneapolis/St. Paul, MN. Intervention modifications were signs encouraging stair use, music, and art posters in stairwells. We collected data before environmental modifications (2006-2007) and at the end of the 2-year intervention (2008-2009). The intervention had a significant positive effect on stair use measured both objectively and via self-report, with greatest increases reported among those participants who used the stairs least at baseline. Following 2-years of continuously-maintained stairwell modifications, increases in both objectively-measured and self-reported stair use were significantly larger at intervention than control worksites. Study findings suggest that the positive impact of environmental modifications on stair use persist over a longer time period than has been previously demonstrated. Results also indicate that infrequent stair users may be most amenable to the behavior changes encouraged by these environmental enhancements.

The Role of Front-of-Package Nutrition Labels with and without Explanatory Videos on Parent and Child Food Choices.

The aim of this research was to determine whether parent/child pairs choosing products from a grocery aisle labeled with front-of-package (FOP) nutrition labels would make more healthful choices than pairs who viewed the same items without labels, and to determine the added value of viewing an explanatory video before choosing. In this experiment, 175 parent/child pairs chose USD 20 worth of packaged foods and beverages from a grocery aisle in a research laboratory and were randomly assigned to see products that either did or did not have 0-4-star FOP labels, with more stars indicating more healthful products. Among those participants with access to FOP labels, half were randomly assigned to view a 30 s video explaining the FOP labels before selecting foods. Participants who saw the explanatory video before selecting among products with FOP labels chose foods with significantly more stars than participants who saw the FOP-labeled products without the video; however, there was no significant difference in mean stars on selected products between the group that saw the videos and the control group that saw neither the video nor FOP labels. We conclude that explaining new FOP labels to consumers may be necessary for the labels to prompt more healthful choices.

The Effect of Mental Activation of One's Pet Dog on Stress Reactivity.

Research suggests that mental activation of human social support may reduce stress reactivity. However, the extent to which social support from pets elicits a similar effect has been less explored. This study aims to determine whether the mental activation of one's pet dog reduces stress reactivity to a subsequent experimental stressor. In a 2 × 2 design, 132 dog-owning participants (Mage = 20.14; 80% female) were randomly assigned to one of two mental activation conditions (pet dog; general) and one of two stressor conditions (social-evaluative; cognitive). Data were analyzed with two-way ANOVAs with self-reported (positive/negative affect, negative self-evaluation) and physiological (blood pressure, heart rate) dependent variables. Results indicated that participants randomized to the pet dog mental activation condition had smaller decreases in positive affect from baseline to post-stressor compared to the general mental activation condition. However, there were no significant interactions between time and mental activation condition on negative affect, negative self-evaluation, heart rate, or blood pressure. Thus, the mental activation of one's pet dog had a minimal effect on stress reactivity to a cognitive or social-evaluative stressor. Results suggest that the physical presence of an animal may be an essential mechanism underlying the benefits of animal-derived social support.

Motivational Profile as a Predictor of Physical Activity Among US Adults During the Early Months of the COVID-19 Pandemic: A Daily Diary Study.

This study used a daily diary approach to examine associations between day-level physical activity (PA) behavior, PA-specific motivational profile, and days since the COVID-19 national emergency declaration during the early months (April-June 2020) of the pandemic. A total of 468 US adults (Mage = 34.8 y, 79% female) participated in a 28-day smartphone-based daily diary study assessing PA. A baseline survey assessed PA and motivation for PA using the Behavioral Regulation in Exercise Questionnaire. Multilevel linear regression models examined the main effects and interactions of motivational profile and time (days since the US March 13, 2020, COVID-19 national emergency declaration) on daily PA minutes. Latent profile analysis identified 4 distinct motivational profiles for PA among this sample: profile 1: high amotivation (n = 100, 21%); profile 2: low controlled motivation (n = 55, 12%); profile 3: high external regulation (n = 47, 10%); and profile 4: moderate autonomous motivation (n = 266, 57%). After controlling for baseline PA, there were significant interactions between profile and time on daily PA (-0.21, P < .01). Profile 2 showed greater decreases in daily PA minutes over time than profile 1 (b = -0.29, P < .01). Profiles 3 and 4 did not indicate significant decreases in PA compared with profile 1 (b = 0.14, P = .31 and b = -0.16, P = .05, respectively). Contrary to previous research, individuals with lower controlled or moderate autonomous motivation demonstrated the largest decreases in PA over time, whereas individuals with higher amotivation or external regulation demonstrated smaller decreases over time. These findings suggest that external motivation may have provided short-term protection against declines in PA observed during early months of the COVID-19 pandemic.

Changes in Adults' Eating Behaviors During the Initial Months of the COVID-19 Pandemic: A Narrative Review.

Factors such as regulations and health concerns shifted daily habits, including eating behaviors, during the early months of the coronavirus disease 2019 (COVID-19) pandemic. This comprehensive narrative review synthesizes research on eating behavior changes during the early months of the pandemic (February to June 2020), including changes in amount, rate, and timing of food consumption, types and healthfulness of foods consumed, the occurrence of other specified eating behaviors (eg, restrained eating or binging), and reasons for eating (eg, stress or cravings), among adults. A literature search using three EBSCOhost databases and Google Scholar was conducted to identify relevant articles made available in 2020. A total of 71 articles representing 250,715 individuals from more than 30 countries were reviewed. Findings show eating behaviors changed little during the early COVID-19 pandemic for most participants. Among those whose eating behaviors changed, increases in both intake and frequency of eating meals and snacks were more common than decreases. Findings on timing of eating and healthfulness of food consumed showed mixed results. However, when changes occurred in the type of food consumed, increases were more common for snacks, homemade pastries, white bread/pasta, legumes, and fruits/vegetables; decreases were more common for meats, seafood/fish, frozen foods, fast food, dark breads/grains, and dark leafy green vegetables. During the pandemic, binging, uncontrolled eating, and overeating increased, meal skipping decreased, and restrictive eating had mixed findings. Changes in factors such as emotions and mood (eg, depression), cravings, and environmental factors (eg, food insecurity) were related to changes in eating behaviors. Findings can inform clinical practitioners in efforts to mitigate disruptions to normal, healthy eating patterns among adults both in and outside of global health catastrophes.

Virtual reality assessment of walking in a modifiable urban environment: a feasibility and acceptability study.

Physical activity is known to be one of the most health-beneficial behaviors, and salutogenic design modifications to the built environment can facilitate increased physical activity. Unfortunately, it is not often clear in advance which environmental and urban design implementations will generate increases in activities such as walking, and which will have little impact or even reduce walking. The present study tested the feasibility and acceptability of a virtual reality (VR) model for pre-testing urban designs for their impact on walking. Using a wearable VR head-mounted display/computer, young adults (n = 40) walked freely through a large indoor gymnasium, simultaneously walking through a virtual model of an urban streetscape that was designed to be modifiable and allow for testing impacts on walking of various changes to the urban environment. The majority of participants found the experience to be acceptable: pleasant and nonaversive, and they walked freely through the VR model for approximately 20 min, on average. Using modifiable VR models to pre-test built-environment changes for their impacts on walking behavior appears to be a feasible and acceptable approach and worthy of continued research investigation.

Predictors of nutrition label viewing during food purchase decision making: an eye tracking investigation.

OBJECTIVE: Nutrition label use could help consumers eat healthfully. Despite consumers reporting label use, diets are not very healthful and obesity rates continue to rise. The present study investigated whether self-reported label use matches objectively measured label viewing by monitoring the gaze of individuals viewing labels. DESIGN: The present study monitored adults viewing sixty-four food items on a computer equipped with an eye-tracking camera as they made simulated food purchasing decisions. ANOVA and t tests were used to compare label viewing across various subgroups (e.g. normal weight v. overweight v. obese; married v. unmarried) and also across various types of foods (e.g. snacks v. fruits and vegetables). SETTING: Participants came to the University of Minnesota's Epidemiology Clinical Research Center in spring 2010. SUBJECTS: The 203 participants were ≥18 years old and capable of reading English words on a computer 76 cm (30 in) away. RESULTS: Participants looked longer at labels for 'meal' items like pizza, soup and yoghurt compared with fruits and vegetables, snack items like crackers and nuts, and dessert items like ice cream and cookies. Participants spent longer looking at labels for foods they decided to purchase compared with foods they decided not to purchase. There were few between-group differences in nutrition label viewing across sex, race, age, BMI, marital status, income or educational attainment. CONCLUSIONS: Nutrition label viewing is related to food purchasing, and labels are viewed more when a food's healthfulness is ambiguous. Objectively measuring nutrition label viewing provides new insight into label use by various sociodemographic groups.

Environmental Physical Activity Cues and Children's Active vs. Sedentary Recreation.

Physical activity (PA) benefits health, and intensive environmental modifications can increase children's PA. Research has not yet addressed if subtle environmental cues, such as posters depicting PA, increase child PA. In the current study, it was hypothesized that children exposed to active posters (vs. nature posters) would spend a larger proportion of free play time engaging with active toys (relative to sedentary toys). Participants were randomly assigned to one of two conditions in which posters on a laboratory wall depicted 1. People being active, or 2. Nature scenes. Children aged 5-10 years (N = 175) could play with up to eight toys (four active, four sedentary) while parents completed study-related surveys. The proportion of playtime that was active was compared between groups. Poster type did not have a significant effect on proportion of active playtime. Previous environmental interventions that increase children's PA have done so through enhancing access to active opportunities, rather than via signage. It is possible that poster interventions such as this may not influence children's PA, or perhaps other types of cues would have been more effective. Future research should investigate subtle environmental cues that match both the target audience and the accessible PA options (e.g., posters depicting children playing with available active toys) and explore other low-investment environmental modifications to boost children's PA.

Environmental resources moderate the relationship between social support and school sports participation among adolescents: a cross-sectional analysis.

BACKGROUND: Most Americans are not active at recommended levels. Adolescence is a developmental period when physical activity (PA) decreases markedly. METHODS: This study investigates whether access to environmental PA resources moderates the relationship between psychosocial resources (social support and perceived competence) and PA among 192 adolescents. RESULTS: Environmental access to PA resources (determined via GIS-based assessment of the number of gyms, schools, trails, parks and athletic fields within 0.5 miles of each participant's home) moderated the association between social support and PA; among adolescents with high levels of environmental resources, greater social support was associated with students participating in a greater number of sports in school, whereas no such relationship emerged among adolescents with low environmental resources. CONCLUSIONS: PA-promotion interventions should aim to enhance both social and environmental resources; targeting either one alone may be insufficient.

Adolescents' attitudes toward sports, exercise, and fitness predict physical activity 5 and 10 years later.

OBJECTIVE: To determine whether adolescent attitudes towards sports, exercise, and fitness predict moderate-to-vigorous physical activity 5 and 10 years later. METHOD: A diverse group of 1902 adolescents participating in Project Eating and Activity in Teens, reported weekly moderate-to-vigorous physical activity and attitudes toward sports, exercise, and fitness in Eating and Activity in Teens-I (1998-99), Eating and Activity in Teens-II (2003-04), and Eating and Activity in Teens-III (2008-09). RESULTS: Mean moderate-to-vigorous physical activity was 6.4, 5.1, and 4.0 hours/week at baseline, 5-year, and 10-year follow-up, respectively. Attitudes toward sports, exercise, and fitness together predicted moderate-to-vigorous physical activity at 5 and 10 years. Among the predictors of 5- and 10-year moderate-to-vigorous physical activity, attitude's effect size, though modest, was comparable to the effect sizes for sports participation and body mass index. Adolescents with more-favorable attitudes toward sports, exercise, and fitness engaged in approximately 30%-40% more weekly moderate-to-vigorous physical activity at follow-up (2.1 hour/week at 5 years and 1.2 hour/week at 10 years) than those with less-favorable attitudes. CONCLUSION: Adolescents' exercise-related attitudes predict subsequent moderate-to-vigorous physical activity independent of baseline behavior suggesting that youth moderate-to-vigorous physical activity promotion efforts may provide long-term benefits by helping youth develop favorable exercise attitudes.

Veterinary-Prescribed Physical Activity: Feasibility and Acceptability among Veterinary Staff and Dog Owners.

Physical inactivity remains a global epidemic leading to an estimated 5 million preventable deaths per year. Although there exist numerous public-health campaigns aimed at increasing physical activity (PA), a potentially fruitful but underexplored avenue to promote both human and animal health is veterinary-prescribed PA programs. The aim of this study was to determine the feasibility and acceptability of incorporating veterinary-prescribed PA programming into a diverse array of clinic settings. Participants (n = 722 veterinary-clinic staff (VS); n = 1028 dog owners (DOs)) completed an online survey assessing: (a) the perceived importance of PA for promoting health and preventing disease, (b) willingness to participate in a veterinary-prescribed PA program, and (c) potential benefits and barriers of such a program. Both groups of participants indicated that PA is important for both human and animal health (97% and 98% of VS and 92% and 93% of DOs said PA is very or extremely important for animal and human health, respectively). Additionally, most participants in both groups expressed an interest in participating in a veterinary-prescribed PA program in the future, with only 11% of DOs and 10% of VS saying they were not interested. Benefits and barriers of this type of intervention for both practitioners and patients were also identified. Incorporating veterinary-prescribed PA programming into veterinary clinics seems to be acceptable to both DOs and VS. Additionally, many VS believe such programming would be feasible at their clinics; thus, pursuing such programs appears to be a promising avenue for promoting human and animal health.

GMO Food Labels Do Not Affect College Student Food Selection, Despite Negative Attitudes towards GMOs.

US Public Law 114-216 dictates that food producers in the United States of America will be required to label foods containing genetically modified organisms (GMOs) starting in 2022; however, there is little empirical evidence demonstrating how U.S. consumers would use food labels that indicate the presence or absence of GMOs. The aim of this two-phase study was to determine how attitudes towards GMOs relate to food choices and how labels indicating the presence or absence of GMOs differentially impact choices among college students-the age group which values transparent food labeling more than any other. Participants (n = 434) made yes/no choices for each of 64 foods. In both phases of the study, participants were randomly assigned to seeing GMO Free labels, contains GMOs labels, or no GMO labels. Across the two phases, 85% of participants reported believing that GMOs were at least somewhat dangerous to health (42% believed GMOs to be dangerous), yet in both studies, although eye-tracking data verified that participants attended to the GMO labels, these labels did not significantly affect food choices. Although college consumers may believe GMOs to be dangerous, their food choices do not reflect this belief.

Maintenance-tailored therapy vs. standard behavior therapy for 30-month maintenance of weight loss.

OBJECTIVE: To assess differences in weight regain one year after an 18-month obesity treatment with standard behavior therapy (SBT) or maintenance-tailored therapy for obesity (MTT). METHOD: 213 obese adult volunteers were treated for 18 months using SBT with fixed behavioral prescriptions or MTT that employed varied behavioral prescriptions with treatment breaks. Follow-up analysis focused on weight maintenance after a year of no contact. The trial was conducted at the University of Minnesota between 2005 and 2009. RESULTS: Mean (SD) weight change between 18 and 30 months for participants in the SBT group was +4.1 kg (4.4) compared to +2.8 kg (4.5) in the MTT group. This is a 31% reduction in weight regain in MTT relative to SBT (p=0.078). This trend toward better maintenance in MTT versus SBT was due primarily to superior differential maintenance in MTT participants in the highest tertile of total weight loss at 18 months, i.e. MTT participants in this tertile regained 4 kg less than SBT participants between 18 and 30 months. CONCLUSIONS: The MTT approach with varied content and timing produced more desirable patterns of weight loss maintenance than the traditional SBT approach, especially among individuals who had achieved greater initial weight loss.
