“…For screening purposes, participants scoring ≥14 points (possible range 0–63) on the BDI-II were considered to be at least mild-to-moderately depressed. Our lab has previously reported that decreased HRV was associated with depressive symptoms among firefighters (Liao et al, 2014). The Cronbach’s alpha for the BDI-II survey in the sample was 0.86.…”

Background Autonomic dysfunction is an important propagator of cardiometabolic disease and can be measured using multiple metrics such as heart rate variability (HRV) and heart rate recovery (HRR). The relationships between HRV and HRR have not been fully examined, nor have the relationships between HRV, HRR, and other physiological measures linked to cardiometabolic disease (e.g., blood pressure recovery). Evaluation of these additional relationships may provide new insights into the association between autonomic function and cardiometabolic disease especially among high-risk groups like firefighters. Methods 92 firefighters (96% male, 81% white) without overt cardiovascular disease underwent exercise testing with continuous heart rate (HR) and blood pressure (BP) monitoring. HRR was the difference between maximal HR and HR 1-minute post-exercise; BP recovery (BPR) was the difference between maximal BP and BP 2-minute post-exercise. Afterwards, participants underwent 24-hour electrocardiographic monitoring to measure HRV. Unadjusted Spearman correlations and adjusted partial Spearman correlations were computed. Between group analyses were also conducted with Kruskal–Wallis test. Results Associations between HRV and HRR poorly converged (RMSSD and HRR, unadjusted = 0.235; adjusted = 0.144). SDNN Index exhibited the strongest association with parasympathetic tone exhibited by overall lower HRs (unadjusted = −0.600; adjusted = −0.631). HRR demonstrated stronger associations with systolic and diastolic BP responses during exercise (SBP Recovery unadjusted = 0.267; adjusted = 0.297; DBP Recovery unadjusted = −0.276; adjusted = −0.232). Conclusions Overall, while HRV metrics converged and were associated with lower resting heart rates, HRV and HRR poorly converged. Interestingly, HRR was related with measures of hemodynamics indicating a potential relationship with vascular function during both maximal exercise and exercise recovery.

“…Additionally, it has been shown that lower HRV in depressed individuals refl ects impaired integration of brain mechanisms underlying eff ective autonomic and behavioral control (underlying obesity) [11]. Multiple studies indicate that some reduced parameters in HRV analysis values are characteristic of depressed individuals [10,15,21,42]. It has also been shown that lower HRV parameters positively correlate with the severity of the depression symptoms [19].…”

Own sources Source of support:Heart rate variability (HRV) provides valuable information in various clinical settings. Limited information exists on changes in cardiac autonomic modulation in extremely obese patients (BMI>40). The aim of this study was to investigate the infl uence of extreme (morbid) obesity and concomitant diseases on cardiovascular autonomic function. Participants of this study are 40 women and 40 men with a mean age of 47.9 diagnosed with morbid obesity (mean BMI 47.49) and hospitalized to further bariatric treatment. In 42 patients diagnosed with hypertension (treated with beta blockers and ACE inhibitors along with well controlled blood pressure), type 2 diabetes (treatment with oral drugs) also occurred. Furthermore, 46 patients were diagnosed with depression. None of the participants used antidepressants or sedative agents. A total of 80 healthy people (40 women and 40 men) with a mean age of 42.7 and with a mean BMI of 24.6 formed the control group. All patients had 24-hour ECG monitoring using the Holter method in order to evaluate the autonomic activity with time and frequency domain analysis (heart rate variability -HRV).

“…Apart from extinguishing fires, firefighters also have additional strenuous work duties, such as rescuing people in dangerous situations and providing first aid and emergency medical services while working irregular hours 1 4. These types of strenuous working conditions place significant strain on firefighters’ musculoskeletal and cardiovascular systems, predisposing them to higher risk of severe injuries and sudden cardiac events while on duty 1 4–10…”

Effects of cardiovascular health, musculoskeletal health and physical fitness on occupational performance of firefighters: protocol for a systematic review and meta-analysis

et al. 2022

View full text Add to dashboard Cite

IntroductionFirefighting is a hazardous occupation, where firefighters are involved in life-threatening situations, being placed under tremendous physical strain, while wearing heavy and insulated equipment to protect them from chemicals, fumes and high temperatures. This necessitates that firefighter stay in good physical condition and maintain adequate cardiovascular fitness to cope with these stressors and perform their duties with minimal health risks. The aim of this systematic review and meta-analysis is to determine the effect of cardiovascular health, musculoskeletal health and physical fitness on the occupational performance of firefighters.Methods and analysisAll study types and designs will be included and appraised. The following electronic databases will be searched: PubMed/Medline, Scopus, Web of Science, Embase, EBSCOHost and CINAHL, with no restrictions on publication date. The literature search will be conducted comprehensively to enable the capturing of as many relevant articles as possible but will be limited to English-language papers only. A combination of the appropriate terms (search string) will be used to ensure the inclusion of the relevant components of the participants, exposure, comparison and outcome. A researcher-generated form with the key characteristics of each study will be used to retrieve all relevant details from the selected studies for initial eligibility screening. The Rayyan Intelligent Systematic Review tool will be used to screen and select studies for inclusion, and information from the included studies will be captured on the researcher-generated data extraction form. The The appraisal tool for cross-sectional studies (AXIS) checklist and the Critical Appraisal Skills Programme toolkit will be used to conduct the methodological assessment of each study. Data will be analysed using Review Manager V.5.3. Generated results will be presented using a combination of figures, graphs and tables. The synthesis of quantitative data (using a meta-analysis methodology) will involve the integration of quantitative findings from multiple studies to achieve coherence.Ethics and disseminationThis study obtained ethical clearance from the University of the Western Cape Biomedical Research Ethics Committee (BM21/10/9). We will disseminate the findings of in peer-reviewed journals and at national and international conferences. The protocol will form part of a chapter for a doctoral thesis.PROSPERO registration numberCRD42021258898.
