Emphasizing appeal over health promotes preference for nutritious foods in people of low socioeconomic status.

People of low socioeconomic status (SES) have disproportionately poorer dietary health despite efforts to improve access and highlight the health benefits of nutritious foods. While health-focused labels and advertisements make healthier options easier to recognize, they can prime a number of negative associations about healthy foods (e.g., taste, satiety, cost), which may be particularly aversive for low SES groups. This within-subjects study recruited people of low and high SES (those without and with a college degree) and compared their product expectations, experiences, satiety, and choice when consuming a bottled fruit and vegetable smoothie promoted as pleasurable ("Crave") or as healthy ("Nutralean"). Relative to Nutralean, Crave improved product expectations and behavioral measures of satiety across all participants. However, Crave enhanced expectations, experiences, and product choice more for low SES than high SES participants. Importantly, improvements were achieved without deception of nutritional facts and without decreasing perceived healthiness or increasing perceived cost. These findings identify SES as an important moderator in health-focused promotion and suggest how the rapidly growing healthy food industry can more effectively appeal to low SES groups, contexts which the majority of Americans navigate.

Mindset is associated with future physical activity and management strategies in individuals with knee osteoarthritis.

BACKGROUND: Despite the benefits of physical activity for individuals with knee osteoarthritis (KOA), physical activity levels are low in this population. OBJECTIVES: We conducted a repeated cross-sectional study to compare mindset about physical activity among individuals with and without KOA and to investigate whether mindset relates to physical activity. METHODS: Participants with (n = 150) and without (n = 152) KOA completed an online survey at enrollment (T1). Participants with KOA repeated the survey 3 weeks later (T2; n = 62). The mindset questionnaire, scored from 1 to 4, assessed the extent to which individuals associate the process of exercising with less appeal-focused qualities (e.g., boring, painful, isolating, and depriving) versus appeal-focused (e.g., fun, pleasurable, social, and indulgent). Using linear regression, we examined the relationship between mindset and having KOA, and, in the subgroup of KOA participants, the relationship between mindset at T1 and self-reported physical activity at T2. We also compared mindset between people who use medication for management and those who use exercise. RESULTS: Within the KOA group, a more appeal-focused mindset was associated with higher future physical activity (ß=38.72, p = 0.006) when controlling for demographics, health, and KOA symptoms. Individuals who used exercise with or without pain medication or injections had a more appeal-focused mindset than those who used medication or injections without exercise (p<0.001). A less appeal-focused mindset regarding physical activity was not significantly associated with KOA (ß = -0.14, p = 0.067). Further, the mindset score demonstrated strong internal consistency (α = 0.92; T1; n = 150 and α = 0.92; T2; n = 62) and test-retest reliability (intraclass correlation coefficient (ICC) > 0.84, p < 0.001) within the KOA sample. CONCLUSIONS: In individuals with KOA, mindset is associated with future physical activity levels and relates to the individual's management strategy. Mindset is a reliable and malleable construct and may be a valuable target for increasing physical activity and improving adherence to rehabilitation strategies involving exercise among individuals with KOA.

Can Exercising and Eating Healthy Be Fun and Indulgent Instead of Boring and Depriving? Targeting Mindsets About the Process of Engaging in Healthy Behaviors.

This paper investigates mindsets about the process of health behaviors-the extent to which people associate physical activity and healthy eating with appealing (pleasurable, fun, indulgent) versus unappealing (unpleasant, boring, depriving) qualities-to promote greater engagement. Study 1 (N = 536) examined how mindsets about physical activity and healthy eating relate to current and future health behavior. Study 2 (N = 149) intervened in actual fitness classes to compare the effects of brief appeal-focused and health-focused interventions on mindsets about physical activity and class engagement. Study 3 (N = 140) designed nutrition education classes that emphasized either the appeal or the importance of fruits and vegetables for health and compared its effects on mindsets about healthy eating and actual fruit and vegetable consumption. Holding more appealing mindsets about health behaviors predicts subsequent physical activity and healthy eating (Study 1). An intervention targeting mindsets about the appeal of physical activity promotes greater participation in fitness classes than emphasizing the importance of meeting activity guidelines (Study 2). Meanwhile, interventions targeting mindsets about the appeal of healthy eating increases in-class fruit and vegetable selection more than emphasizing the importance of eating nutritious foods (Study 3), however additional work is needed to sustain such changes in eating behavior. These studies suggest mindsets about the process of health behaviors can be influential and changeable factors in motivating physical activity and healthy eating.

Learning one's genetic risk changes physiology independent of actual genetic risk.

Millions of people now access personal genetic risk estimates for diseases such as Alzheimer's, cancer and obesity1. While this information can be informative2-4, research on placebo and nocebo effects5-8 suggests that learning of one's genetic risk may evoke physiological changes consistent with the expected risk profile. Here we tested whether merely learning of one's genetic risk for disease alters one's actual risk by making people more likely to exhibit the expected changes in gene-related physiology, behaviour and subjective experience. Individuals were genotyped for actual genetic risk and then randomly assigned to receive either a 'high-risk' or 'protected' genetic test result for obesity via cardiorespiratory exercise capacity (experiment 1, N = 116) or physiological satiety (experiment 2, N = 107) before engaging in a task in which genetic risk was salient. Merely receiving genetic risk information changed individuals' cardiorespiratory physiology, perceived exertion and running endurance during exercise, and changed satiety physiology and perceived fullness after food consumption in a self-fulfilling manner. Effects of perceived genetic risk on outcomes were sometimes greater than the effects associated with actual genetic risk. If simply conveying genetic risk information can alter actual risk, clinicians and ethicists should wrestle with appropriate thresholds for when revealing genetic risk is warranted.

Americans' Health Mindsets: Content, Cultural Patterning, and Associations With Physical and Mental Health.

BACKGROUND: Health mindsets are mental frameworks that help people recognize, organize, interpret, and respond to health-relevant information. Although mindsets shape health behaviors and outcomes, no study has examined the health mindsets of ethnically and socioeconomically diverse Americans. PURPOSE: We explored the content, cultural patterning, and health correlates of diverse Americans' health mindsets. METHODS: Two studies surveyed approximately equal numbers of African American, Asian American, European American, and Latinx American men and women of lower and higher socioeconomic status (SES). Study 1 (N = 334) used open-ended questions to elicit participants' mindsets about the definitions, causes, and benefits of health. Study 2 (N = 320) used Study 1's results to develop a closed-ended instrument. RESULTS: In Study 1, open-ended questioning revealed six overarching mindset themes: behavioral, medical, physical, psychological, social, and spiritual. The most prevalent mindsets were psychological definitions, behavioral causes, and psychological benefits. Participants mentioned more cause themes than definition or benefit themes, and mindset theme mentions correlated with worse health. Older participants mentioned more themes than younger, women mentioned more definition themes than men, and low-SES participants mentioned more cause themes than high-SES participants. In Study 2, closed-ended scales uncovered more complex and positive health mindsets. Psychological and spiritual benefit mindsets correlated with good mental health. African Americans and women endorsed the widest array of mindsets, and the spiritual benefit mindset partially explained the superior mental health of African Americans. CONCLUSIONS: Many Americans hold simplistic, illness-focused health mindsets. Cultivating more complex, benefit-focused, and culturally appropriate health mindsets could support health.
