“…Very few individuals in the encouraging condition had these concerns and exhibited more positive reactions to the message overall. These results are consistent with the literature on positivity (e.g., Clemens et al, 2021;Li et al, 2016) and overwhelming evidence in the obesity literature that shaming and stigmatization are ineffective and related to more negative health behaviors (see Zhu et al, 2022 for a review).…”

Following the release of the first COVID‐19 vaccinations many people utilized social media to promote vaccination among their social circles. These attempts to persuade others to get vaccinated ranged from positive encouragement (e.g., emphasizing the prosocial benefits and positive outcomes) to shame and threats (e.g., name calling and threating to end friendships over vaccination status). The present study investigated how these different social media messages affected COVID‐19 vaccination intentions. In June 2021, shortly after vaccines had been made freely available to anyone over the age of 16 in the United States, unvaccinated participants read a manipulated Twitter message designed to be either encouraging or shaming. Message‐type did not significantly affect intentions to become vaccinated against COVID‐19; however, participants who saw the encouraging message reported that the post made them feel more likely to get vaccinated. Self‐efficacy was also manipulated but did not reveal any significant effects. Additional analyses suggest that having personal experience with COVID‐19 moderates reactions to these different messages. We discuss limitations and promising avenues for future research on the effects of social media messages on health behaviors.

“…Weight stigma may also lead to weight gain through behavioural mechanisms, such as impairing weight management. Those who experience weight stigma are more likely to report overeating and unhealthy eating, and reduced motivation to engage in physical activity (Tomiyama, 2014;Vartanian & Porter, 2016;Vartanian & Shaprow, 2008;Zhu et al, 2022). In line with this literature, previous longitudinal analyses using ELSA and HRS data showed that reporting weight stigma at baseline increased the odds of becoming and/or remaining obese over the follow-up period (Jackson et al, 2014;Sutin & Terracciano, 2013).…”

Objective: Obesity is associated with a range of negative psychological conditions that may also affect physiological health. Across two studies, we tested whether a range of psychological measures explain why obesity is prospectively associated with physiological dysregulation, measured via clinical indicators of cardiovascular, immune system, and metabolic function. Methods: We used comparable 4-year follow-up representative longitudinal data of UK and US older adults (≥ 50 years) from the English Longitudinal Study of Ageing (ELSA) (2008/2009–2012/2013) (Study 1; n= 6,250) and the Health and Retirement Study (HRS) (2008/2010–2012/2014) (Study 2; n=9,664). Fourteen and 21 psychological measures (e.g., depressive symptoms, life satisfaction, weight stigma, positive affect) were tested as candidate mediators in Studies 1 and 2, respectively. Results: Obesity predicted physiological dysregulation at follow-up across both studies. In Study 1, only weight stigma (measured between baseline and follow-up) explained 37% of the association between obesity and physiological dysregulation. In Study 2, only changes in weight stigma from baseline to follow-up (not baseline weight stigma) explained 13% of the effect of obesity on future physiological dysregulation. Mediation by weight stigma in both studies was partially attenuated when changes in body mass index (BMI) from baseline to follow-up were controlled for. No other psychological measures explained the association between obesity and physiological dysregulation in either study. Conclusion: The prospective association between obesity and physiological dysregulation was largely not explained by psychological factors. However, experiencing weight stigma is associated with increased weight gain and this process may explain obesity-related declines in physiological health.
