Lifestyle behaviors and stress are risk factors for overweight and obesity in healthcare workers: a cross-sectional survey

Abstract

Background Overweight and obesity have become major public health concerns worldwide. Persistent stress can activate the human hypothalamic‒pituitary‒adrenal axis (HPA) and increase the intake of “self-rewarding food”, thereby raising the incidence of obesity. Health care workers (HCWs) experience higher workloads and mental stress than workers in many other industries, which may put them at increased risk for overweight/obesity. However, few studies have been carried out on overweight and obesity among HCWs in China, and the overall scenario and behind-the-scenes factors of their overweight and obesity are unknown. The aim of this study is to understand the epidemic of overweight and obesity and risk factors among Chinese HCWs. Methods Based on a cross-sectional web survey design, 23,234 HCWs from 100 health institutions in 5 provinces/autonomous regions/municipalities across China were sampled to answer a self-administered questionnaire that was purposely developed using a multi-staged clustered random-sampling method. Chi-square test and ANOVA were performed to compare variables between two or more groups. Univariate analyses were conducted to identify the influence of self-reported persistent stress and/or recurrent anxiety/depressed mood on lifestyle behaviors. A multivariate binary logistic regression model was used to analyse the risk factors of overweight/obesity. Results Among the respondents, 34.26% were overweight, and 11.22% were obese. Most of the respondents had regular exercise habits (68.17%), had habitually stayed-up late (65.06%) and had been affected by persistent stress and/or recurrent anxiety/depressed mood (62.04%). A higher proportion of those with persistent stress and/or recurrent anxiety/depressed mood than those without habitually staying-up late (76.18%); consumed take-out food (54.92%), fried food (49.93%), snacks or desserts (50.51%); drank sugary drinks (46.57%); smoked (14.27%); and drank alcohol (23.34%). Gender (Female) (OR: 0.314, 95%CI: 0.292–0.336), age (OR: 1.742–2.334, 95%CI: 1.544–2.858), education (OR: 0.620–0.728, 95%CI: 0.445–0.973), living and working area (OR: 1.271, 95%CI: 1.192–1.355), breakfast (OR: 0.898, 95%CI: 0.839–0.960), fried food (OR: 1.133, 95%CI: 1.048–1.224), and alcohol consumption (OR: 1.111, 95%CI: 1.017–1.214) were factors for overweight/obesity. All of the aforementioned results were significant (P < 0.05). Conclusions The overweight/obesity rate of Chinese HCWs is rather high, which might be directly associated with lifestyle behaviors. However, these behaviors fundamentally originated from persistent stress and/or recurrent anxiety/depression, mediated by lifestyle behaviors. Substantial measures should be taken for stress reduction and mental health promotion for overweight/obesity prevention and control among HCWs.

Eating habits of students during a typical exam period-Case of Kosovo

“…This is because emotional situations push students to consume unhealthy foods ISSN: 2252-8806  rich in sugar and fat. Since the stress-food relationship is controlled by hormones and neurotransmitters, such eating is considered one of the main factors in the appearance of obesity [6], [7].…”
