Weight Discrimination and Health Risk Behavior in Racial, Ethnic, and Sexual Minority Adults.

BACKGROUND: People with obesity face significant discrimination due to their weight. Exposure to such discrimination is associated with poor health outcomes. Little is known about pathways that explain that association, and even less is known about those pathways in racial, ethnic, and sexual minorities. Health risk behaviors may serve as one such pathway. PURPOSE: We examined associations between weight discrimination and health risk behaviors and assessed whether associations are moderated by gender, race, ethnicity, or sexual orientation. METHODS: Quota sampling was used to oversample Black (36%), Latino (36%), and sexual minority (29%) adults (n = 2,632) who completed an online survey. Using regression analysis, health risk behaviors (maladaptive eating behaviors, physical inactivity, sitting, smoking, alcohol use, and sleep disturbance) were predicted from previous experience with weight discrimination while controlling for demographic characteristics, BMI, and depressive symptoms. Additional analyses tested for interactions between weight discrimination and key demographic variables (i.e., gender, race, ethnicity, and sexual minority status). RESULTS: Weight discrimination was associated with greater emotional eating, binge eating, unhealthy weight control behaviors, cigarette smoking, problematic alcohol use, and sleep disturbance. Gender moderated the association between weight discrimination and binge eating, alcohol use, and physical activity, with stronger effects observed in men than women. Exploratory analyses provided limited evidence for differential effects of weight discrimination across specific combinations of intersecting identities. CONCLUSIONS: Weight discrimination was associated with engagement in unhealthy behaviors and relationships were largely similar across diverse demographic groups. Health risk behaviors may represent a key pathway through which weight discrimination harms health.

People with high body weight remain one of the most stigmatized groups in the USA and face significant discrimination due to their weight. Experiencing weight discrimination is associated with poor health, yet little is known about the underlying pathways that explain this association and even less is known about those pathways in socially marginalized groups. We investigated unhealthy behavior as a possible a pathway by assessing associations between weight discrimination and several health risk behaviors and identifying whether those associations vary by gender, race, ethnicity, or sexual orientation. A diverse sample of 2,632 U.S. adults completed an online survey. Previous experience with weight discrimination was found to be associated with greater emotional eating, binge eating, unhealthy weight control behaviors, cigarette smoking, problematic alcohol use, and poor sleep. The association between weight discrimination and binge eating, alcohol use, and physical activity was stronger in men than in women, yet exploratory analyses provided limited evidence for differential effects of weight discrimination across specific combinations of intersecting identities. Weight discrimination was associated with engagement in unhealthy behaviors and associations were largely similar across participants from diverse demographic groups. Health risk behaviors may represent a key pathway through which weight discrimination harms health.

Behavioral immune system activity predicts downregulation of chronic basal inflammation.

Here, we present a mechanistically grounded theory detailing a novel function of the behavioral immune system (BIS), the psychological system that prompts pathogen avoidance behaviors. We propose that BIS activity allows the body to downregulate basal inflammation, preventing resultant oxidative damage to DNA and promoting longevity. Study 1 investigated the relationship between a trait measure of pathogen avoidance motivation and in vitro and in vivo proinflammatory cytokine production. Study 2 examined the relationship between this same predictor and DNA damage often associated with prolonged inflammation. Results revealed that greater trait pathogen avoidance motivation predicts a) lower levels of spontaneous (but not stimulated) proinflammatory cytokine release by peripheral blood mononuclear cells (PBMCs), b) lower plasma levels of the proinflammatory cytokine interleukin-6 (IL-6), and c) lower levels of oxidative DNA damage. Thus, the BIS may promote health by protecting the body from the deleterious effects of inflammation and oxidative stress.

Progesterone and women's anxiety across the menstrual cycle.

Animal models and a few human investigations suggest progesterone may be associated with anxiety. Progesterone naturally fluctuates across the menstrual cycle, offering an opportunity to understand how within-person increases in progesterone and average progesterone levels across the cycle correspond to women's anxiety. Across two longitudinal studies, we simultaneously modeled the between- and within-person associations between progesterone and anxiety using multilevel modeling. In Study 1, 100 Polish women provided saliva samples and reported their anxiety at three phases of the menstrual cycle: follicular, peri-ovulatory, and luteal. A significant between-person effect emerged, revealing that women with higher average progesterone levels across their cycles reported higher levels of anxiety than women with lower progesterone cycles. This effect held controlling for estradiol. In Study 2, 61 American women provided saliva samples and reported their attachment anxiety during laboratory sessions during the same three cycle phases. A significant between-person and within-person association emerged: women with higher average progesterone levels reported higher levels of attachment anxiety, and as women's progesterone levels increased across their cycles, so too did their attachment anxiety. These effects held controlling for cortisol. In sum, both studies provide support for a link between menstrual cycle progesterone levels and subjective anxiety.

Fear, anger, fruits, and veggies: interactive effects of emotion and message framing on health behavior.

OBJECTIVE: Message framing is a theoretically grounded health communication strategy designed to motivate action by emphasizing either the benefits of engaging in a particular behavior (gains) or the costs of failing to engage in the behavior (losses). This study investigated whether the effectiveness of a framed message depends on the emotional state of the message recipient. We examined effects of fear versus anger, emotions that frequently occur within the context of health decision-making. METHODS: Undergraduate students (N = 133) were randomly assigned to complete a fear or anger induction task after which they read a gain- or loss-framed pamphlet promoting fruit and vegetable consumption. Fruit and vegetable intake (servings per day) subsequently was assessed over the following 2 weeks. RESULTS: As predicted, a significant frame by emotion interaction was observed, such that participants in the fear condition reported eating more servings of fruits and vegetables after exposure to a loss-framed message than to a gain-framed message. In contrast, participants in the anger condition reported eating (marginally) more servings of fruits and vegetables after exposure to a gain-framed message than to a loss-framed message. Greater increases in fruit and vegetable intake from baseline to follow-up were observed when the message frame was matched to the participant's emotional state. CONCLUSION: The effectiveness of framed health communications depends on the message recipient's current emotional state. Affective factors that are incidental to the behavior recommended in a health communication can affect the relative success of gain- and loss-framed appeals.

The endocrinology of exclusion: rejection elicits motivationally tuned changes in progesterone.

Social exclusion can have profound effects on a vast array of motivated psychological processes, from social withdrawal and aggression to prosocial behavior and social affiliation. The current studies examined motivationally tuned endocrinological consequences of exclusion by measuring the release of progesterone, a hormone that reflects an individual's level of social-affiliative motivation. Results from two experiments indicate that release of progesterone following social exclusion depends on people's levels of social anxiety and rejection sensitivity. Individuals high in social anxiety displayed a drop in progesterone in response to exclusion, a pattern consistent with a lack of affiliative motivation. In contrast, individuals high in rejection sensitivity displayed an increase in progesterone when given an opportunity to reaffiliate, a change consistent with a desire for compensatory social contact. These findings provide new insight into the immediate biological changes precipitated by social exclusion--changes that could initiate a range of motivated social responses.
