Norms and attributions about weight gain during the COVID-19 pandemic.

Objective. Weight gain was common during the first year of the COVID-19 pandemic, potentially creating a new descriptive norm about weight gain. The unique context of a global pandemic may have influenced situational attributions for weight gain that were not typical prior to the pandemic. We examined the effects of the new norm on people's views about responsibility and blame for weight gain.Methods. In two preregistered surveys, we aimed to manipulate the salience of weight gain during COVID-19, and measured views about responsibility and blame for weight gain.Results. Among participants who gained weight, the more common they perceived weight gain to be, the more they felt their own weight gain was understandable (b = 0.09, se = 0.04, p = 0.02), but perceived commonness didn't relate to their feelings of responsibility and blame for weight gain. For participants who didn't gain weight, the perceived commonness of weight gain was associated with less blame towards people who gained weight (b = 0.11, se= 1.46, p = 0.044), but not with responsibility for weight gain.Conclusion. Participants believed weight gain was common during COVID, but this descriptive norm had mixed associations with attributions for one's own and others' weight gain.

Psychosocial context and food healthiness in top-grossing American films.

OBJECTIVE: Healthy eating is shaped by the context. To understand how healthy eating is modeled in popular media, this systematic analysis quantified which contextual factors, character behaviors, and character demographics were associated with food healthiness in popular movies. METHOD: Two researchers content-coded the contextual factors, character behaviors, and character demographics depicted across 9,093 foods in 244 top-grossing Hollywood movies released from 1994-2018. Food healthiness was calculated using the Nutrient Profile Index (0 = least healthy, 100 = healthiest) and coder reliability was assessed. Mixed effects regression models tested whether food healthiness was associated with contextual factors (e.g., geographic locations, social consumption situations, celebrations, foreground placement), character behaviors (actual consumption, food evaluations), and character demographics. RESULTS: Confirming six preregistered hypotheses (all p < .001), foods were less healthy when they were in American versus non-American settings (95% CI: Cohen's d = .29-.39), part of social consumption situations (d = .19-.28) and celebrations (d = .04-.17), and in the foreground versus background (d = .15-.24). The foods that characters actually consumed (d = .30-.42) and evaluated positively (vs. negatively, d = .37-.76) were also less healthy. However, disconfirming a gender hypothesis, female characters did not consume healthier foods than males (d = -.11-.13, p = .45). CONCLUSIONS: Top-grossing Hollywood movies depict different contexts and different character behaviors for healthier versus less healthy foods. Research is needed to understand whether depicting healthy foods in different contexts impacts viewers' beliefs and behavior. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

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.

Sweat rate analysis of ivacaftor potentiation of CFTR in non-CF adults.

To determine if ivacaftor (Kalydeco) influences non-CF human CFTR function in vivo, we measured CFTR-dependent (C-sweat) and CFTR-independent (M-sweat) rates from multiple identified sweat glands in 8 non-CF adults. The two types of sweating were stimulated sequentially with intradermal injections of appropriate reagents; each gland served as its own control via alternating off-on drug tests on both arms, given at weekly intervals with 3 off and 3 on tests per subject. We compared drug effects on C-sweating stimulated by either high or low concentrations of ß-adrenergic cocktail, and on methacholine-stimulated M-sweating. For each subject we measured ~700 sweat volumes from ~75 glands per arm (maximum 12 readings per gland), and sweat volumes were log-transformed for statistical analysis. T-tests derived from linear mixed models (LMMs) were more conservative than the familiar paired sample t-tests, and show that ivacaftor significantly increased C-sweating stimulated by both levels of agonist, with a larger effect in the low cocktail condition; ivacaftor did not increase M-sweat. Concurrent sweat chloride tests detected no effect of ivacaftor. We conclude that ivacaftor in vivo increases the open channel probability (PO) of WT CFTR, provided it is not already maximally stimulated.
