“…The cohort study followed-up over 14 years by Chandola et al [8,37], who examined cumulative work stress, using the Job Strain Questionnaire on four occasions, as a predictor of obesity in a prospective 19-year study of 6,895 men and 3,413 women (aged 35-55 years) in the Whitehall II cohort in London, UK (baseline: 1985-1988), reported a dose-response relationship between work stress and risk of general obesity (BMI 30 kg/m 2 ). Plausible pathophysiological mechanisms in stress-induced weight gain involve direct neuroendocrine effects and indirect effects mediated by adverse health behavior, including changes in eating habits [1], exercise frequency [38], sleep [39], social gradient [40,41], and psychosocial resources [42]. Chronic psychological stress may reduce biological resilience and thus disturb homoeostasis [43] by chronic hyperactivation of the hypothalamic pituitary-adrenal axis or increased adipocyte secretion of adipokines, which favors accumulation of visceral fat, and vice versa [7,13].…”

“…Obesity and overweight are also serious health issues worldwide. Throughout the world, including Asian countries, over 300 million people are obese and an additional billion are overweight [1,2]. Obesity is an important cause of excess mortality and morbidity of various diseases such as diabetes mellitus and cardiovascular disease [3,4].…”

Objectives Overweight and poor psychological wellbeing are becoming serious health issues in the Japanese workplace. Concurrence of those physical and mental conditions has been pointed out, especially in middle-aged workers. Therefore, we tried to determine common risk factors for body weight gain and the deterioration of psychological well-being in male middle-aged office workers using a five-year follow-up study. Methods We administered General Health Questionnaire-12 (GHQ-12) as an indicator of psychological well-being to 110 male workers with ages ranging from 40-59 years, and analyzed the influence of several psychological factors, namely sense of coherence (SOC), health locus of control (HLC), and lifestyle variables such as exercise frequency, alcohol intake, smoking status, and dietary intake on changes of body mass index and GHQ-12 score. ResultsMcNemar's chi-squared test showed significant concurrence of weight gain and deterioration of psychological well-being after five-year follow-up. Low-SOC score, low frequency of exercise, and high-dietary intake at supper were significantly associated with both weight gain and poorer psychological well-being in workers, results which were supported by multiple regression analysis. Conclusions These results suggest that exercise and calorie restriction seem to prevent weight gain and promote psychological well-being in workers. Low SOC, which implies difficulty in coping with stress, may be an important risk factor not only for deterioration of psychological well-being but also for becoming overweight. These assumptions must be confirmed by conducting future intervention studies on SOC and lifestyle including exercise and eating behavior.

“…Total food intake was higher for DOM compared to SUB, and the DOM did not take any meals in the inner chambers, suggesting that SUB did not decrease their intake as a result of the presence or threat of the DOM. Thus, these data suggest that although SUB have adequate access to food, they are nonetheless suppressing their food intake [50]. There may be additional differences in meal patterns among SUB rats that also impact body weight and body composition and these studies are currently ongoing in our laboratory [51,52].…”

Social stress is prevalent in many facets of modern society. Epidemiological data suggest that stress is linked to the development of overweight, obesity and metabolic disease. Although there are strong associations between the incidence of obesity with stress and elevated levels of hormones such as cortisol, there are limited animal models to allow investigation of the etiology of increased adiposity resulting from exposure to stress. Perhaps more importantly, an animal model that mirrors the consequences of stress in humans will provide a vehicle to develop rational clinical therapy to treat or prevent adverse outcomes from exposure to chronic social stress. In the visible burrow system (VBS) model of chronic social stress mixed gender colonies are housed for 2 week periods during which male rats of the colony quickly develop a dominance hierarchy. We found that social stress has significant effects on body weight and body composition such that subordinate rats progressively develop characteristics of obesity that occurs, in part, through neuroendocrine alterations and changes in food intake amount. Although SUB are hyperphagic following social stress they do not increase their intake of sucrose solution as CON and DOM do suggesting that they are anhedonic. Consumption of a high fat diet does not appear to affect development of a social hierarchy and appears to enhance the effect that chronic stress has on body composition. The visible burrow system (VBS) model of social stress may be a potential laboratory model for studying stress-associated metabolic disease, including the metabolic syndrome.

“…For example, stress responses can be triggered when an individual senses a threat, real or implied, to its psychological or physiological well-being. The stressor can be sensed in the present moment or anticipated at some future time (Greenberg et al 2002) and can be perceived and take effect subconsciously (Adam and Epel 2007;Tamashiro et al 2006). Acute stress and chronic stress influence the desire to eat in different ways.…”

Exposure to Cues of Harsh or Safe Environmental Conditions Alters Food Preferences

In humans, psychological stress is positively correlated with an increased desire for certain energy-dense food items, indicating that stress may trigger foraging behavior that adapts to perceived current and future resource availability. However, the extent to which such processes influence desire for different kinds of foods remains unclear. Here, we examine the effects of perceived environmental conditions on food preferences across the food spectrum of dairy, meats, vegetables, fruit, grains, and sweets. We first showed images of 30 different food items to participants and recorded their stated desire to eat each kind of food. We then repeated this procedure after exposing participants to cues of either a harsh or a safe environment. As predicted, we found cues of environmental harshness increased the desirability of energydense food items. However, there was also evidence for decreased desirability for energy-dense food items following exposure to cues of a relatively safe environment. Our findings indicate that simple manipulations of perceived environmental conditions may trigger changes in desire for different kinds of food. Our study has relevance for increasing efforts to understand eating behavior in order to promote uptake of healthier diets.
