Abstract Background Understanding the causes and risk factors of metabolic syndrome is important for promoting population health. Oxidative stress has been associated with metabolic syndrome, and also obstructive sleep apnea. These are two diseases which have common prognostic characteristics for heart disease. The aim of this study was to examine the role of oxidative stress in the concurrent presence of metabolic syndrome and obstructive sleep apnea in a working population. Methods Participants were 163 artisan bakers in Shahroud, Iran, routinely exposed to significant heat stress and other oxidative stress indicators on a daily basis as part of their work. Using a cross-sectional design, data relevant to determining metabolic syndrome status according to International Diabetes Federation criteria, and the presence of obstructive sleep apnea according to the STOP-Bang score, was collected. Analyses included hierarchical binary logistic regression to yield predictors of the two diseases. Results Hierarchical binary logistic regression showed that oxidative stress – alongside obesity, no regular exercise, and smoking – was an independent predictor of metabolic syndrome, but not obstructive sleep apnea. Participants who were obese were 28 times more likely to have metabolic syndrome (OR 28.59, 95% CI 4.91–63.02) and 44 times more likely to have obstructive sleep apnea (OR 44.48, 95% CI 4.91–403.28). Participants meeting metabolic syndrome criteria had significantly higher levels of malondialdehyde (p <  0.05) than those who did not. No difference in oxidative stress index levels were found according to obstructive sleep apnea status. Conclusions Our findings suggest that oxidative stress contributes to the onset of metabolic syndrome, and that obstructive sleep apnea is involved in oxidative stress. Whilst obesity, exercise, and smoking remain important targets for reducing the incidence of metabolic syndrome and obstructive sleep apnea, policies to control risks of prolonged exposure to oxidative stress are also relevant in occupations where such environmental conditions exist.

Obstructive Sleep

Obstructive sleep apnea (OSA) is chronic disorder which is characterized by recurrent pauses of breathing during sleep which leads to hypoxia and its two main pathological sequelae: oxidative stress and chronic inflammation. Both are also associated with cellular senescence. As OSA patients present with higher prevalence of age-related disorders, such as atrial hypertension or diabetes mellitus type 2, a relationship between OSA and accelerated aging is observable. Furthermore, it has been established that these OSA are associated with telomere shortening. This process in OSA is likely caused by increased oxidative DNA damage due to increased reactive oxygen species levels, DNA repair disruptions, hypoxia, chronic inflammation, and circadian clock disturbances. The aim of the review is to summarize study outcomes on changes in leukocyte telomere length (LTL) in OSA patients and describe possible molecular mechanisms which connect cellular senescence and the pathophysiology of OSA. The majority of OSA patients are characterized by LTL attrition due to oxidative stress, hypoxia and inflammation, which make a kind of positive feedback loop, and circadian clock disturbance.

Aim: To determine and compare gamma glutamyl transferase (GGT) and fibrinogen among obese males with and without obstructive sleep apnea (OSA). Second objective was to investigate correlation between blood pressure and GGT. Methodology: Sixty-four obese males aged 20-45 years with BMI > 25kg/m2 were included by convenience sampling. The study was conducted, after obtaining ethical approval from IRB, at the Department of Physiology, Post Graduate Medical Institute, Lahore from August 2014 to May 2015. Participants having acute or chronic inflammatory conditions were excluded. Participants were screened for OSA by Berlin and STOP BANG questionnaires. Diagnosis of OSA was made by overnight portable pulse oximetry. The participants were divided into two groups. Group I had 32 obese males with OSA. Group II contained 32 obese males without OSA. After an overnight fasting of 10-12 hours blood samples were drawn. Serum fibrinogen and GGT were measured by spectrophotometer. The data was analyzed using SPSS-22. Quantitative variables were compared between the two groups by Mann-Whitney U test. Spearman correlation was used to correlate blood pressure and GGT among the participants. Results: Fibrinogen was significantly raised (p=0.015) in obese males with OSA. Systolic blood pressure (p=0.003), diastolic blood pressure (p=0.001) and mean arterial blood pressure (p<0.001) showed strong positive correlation with GGT in obese males with OSA. Conclusion: Proinflammatory, procoagulant and proatherogenic marker fibrinogen levels were significantly raised in obese otherwise healthy males with OSA. Oxidative stress marker GGT showed strong positive correlation with blood pressure in obese males with OSA. Keywords: Fibrinogen, gamma glutamyl transferase, inflammation, obstructive sleep apnea, oxidative stress
