I’m Not Just Fat, I’m Old: Has the Study of Body Image Talk Overlooked “Old Talk?”

Background: Research indicates that body dissatisfaction is correlated with and often predictive of both physical and mental health problems. “Fat talk,” a well-studied form of body image talk in adolescents and university-aged women, has been implicated as contributing to body dissatisfaction and mediating the relationship between body dissatisfaction and other mental health problems. Limited research, however, has investigated fat talk across the female lifespan. Further, consistent with most body image research, fat talk research solely focuses on the thin dimension of idealized female attractiveness, even though other dimensions may contribute to body dissatisfaction in women. Method: The current study investigated whether or not “old talk,” a hereto un-described form of body image talk, appears to be a parallel, but distinct, form of body image talk that taps into the young dimension of the thin-young-ideal standard of female beauty. An international, internet sample of women (aged 18-87, N = 914) completed questionnaires aimed at assessing fat talk, old talk, body image disturbance, and eating disorder pathology. Results: Results indicated that both fat talk and old talk were reported by women across the lifespan, although they evidenced different trajectories of frequency. Like fat talk, old talk was significantly correlated with body image disturbance and eating disorder pathology, albeit at a lower rate than fat talk in the total sample. Old talk was more highly correlated with ageing appearance anxiety than fat talk, and the correlation between old talk and body image disturbance and ED pathology increased with women’s ages. Conclusion: Results suggest that old talk is a form of body image talk that is related to but distinct from fat talk. Old talk appears to be similarly problematic to fat talk for women whose age increases their deviation from the thin-young-ideal. Further research into the phenomenon of old talk is warranted as is increased attention to fat talk across the full lifespan of women

AIRWAY HYDROGEN PEROXIDE DURING A NATURALISTIC PERIOD OF SUSTAINED PSYCHOLOGICAL STRESS IN INDIVIDUALS WITH ASTHMA AND HEALTHY CONTROLS

Reactive oxygen species in the form of exhaled hydrogen peroxide (H2O2) and nitric oxide (NO) are important biological markers of inflammation and immune response in the airways of both asthmatics and healthy individuals. Previous research has linked psychological distress to changes in these processes in the airways, which can impact overall disease management outcomes. The current study examined changes in H2O2, NO, mood, and other physiological measures during times of prolonged stress using a naturalistic paradigm. Both healthy and asthmatic participants were assessed at three separate time periods; once during a low stress period mid-semester, and twice during the week of final examinations. At each session, participants completed questionnaires regarding mood, social support, stress, cold symptoms, and physical activity. They also provided saliva samples, a blood pressure measurement, and several measures of lung function and airway physiology. Online surveys of stress and cold symptoms were completed one week after final examinations. Mixed models analyses were used to examine changes mood and physiological variables both between and within participants across time. Significant changes were found for stress, negative affect, H2O2, and NO. Implications for these results are discussed as well as directions for future research endeavors

Acute ingestion of beetroot juice increases exhaled nitric oxide in healthy individuals.

Nitric oxide (NO) plays an important role in the airways' innate immune response, and the fraction of exhaled NO at a flow rate of 50mL per second (FENO50) has been utilized to capture NO. Deficits in NO are linked to loss of bronchoprotective effects in airway challenges and predict symptoms of respiratory infection. While beetroot juice supplements have been proposed to enhance exercise performance by increasing dietary nitrate consumption, few studies have examined the impact of beetroot juice or nitrate supplementation on airway NO in contexts beyond an exercise challenge, which we know influences FENO50.We therefore examined the influence of a beetroot juice supplement on FENO50 in healthy males and females (n = 38) during periods of rest and in normoxic conditions. FENO50, heart rate, blood pressure, and state affect were measured at baseline, 45 minutes, and 90 minutes following ingestion of 70ml beetroot juice (6.5 mmol nitrate). Identical procedures were followed with ingestion of 70ml of water on a control day.After beetroot consumption, average values of the natural log of FENO50 (lnFENO50) increased by 21.3% (Cohen's d = 1.54, p < .001) 45 minutes after consumption and by 20.3% (Cohen's d = 1.45, p < .001) 90 min after consumption. On the other hand, only very small increases in FENO50 were observed after consumption of the control liquid (less than 1% increase). A small subset (n = 4) of participants completed an extended protocol lasting over 3 hours, where elevated levels of FENO50 persisted. No significant changes in cardiovascular measures were observed with this small single dose of beetroot juice.As NO serves a key role in innate immunity, future research is needed to explore the potential clinical utility of beetroot and dietary nitrate to elevate FENO50 and prevent respiratory infection

Towards an assessment of perceived COPD exacerbation triggers: Initial development and validation of a questionnaire

BACKGROUND AND OBJECTIVE: Prevention of exacerbations in chronic obstructive pulmonary disease (COPD) is important to decrease overall declines in functioning and improve quality of life. The present study sought to develop a psychometrically valid measure of perceived triggers of exacerbations in COPD patients, the COPD Exacerbation Trigger Inventory (CETI). METHODS: Participants (n = 192) were recruited through local clinics and online to complete surveys of the CETI, demographic information, disease-specific information and the COPD Assessment Test (CAT). The CETI included a free response section on patients' individual top triggers, combined with ratings of their controllability. RESULTS: Exploratory principal component analyses identified a stable 5-factor structure (33 items), from which trigger subscales for weather/climate, air pollution/irritants, exercise, infection/illness and psychological factors were formed (internal consistency Cronbach's α = 0.90-0.94). Trigger factors were associated with COPD functional status, exacerbation frequency and healthcare utilization. Participants found personal triggers related to dust, air pollution, smoking and physical activity to be the most easily controlled, whereas those related to psychological factors, climate, infection, respiratory symptoms and sleep to be more difficult to control. Greater perceived controllability of triggers was associated with lower CAT scores, indicating better health status and less impact of the disease on functioning. CONCLUSION: The CETI is a psychometrically valid measure of perceived exacerbation triggers in patients with COPD. Perceived triggers are associated with clinical outcomes. Assessment of trigger classes and their controllability may prove useful in both research and clinical settings with COPD patients and to further our knowledge in prevention and disease management.status: publishe
