Cardiometabolic health among United States firefighters by age.

Firefighting is strenuous work that results in considerable cardiovascular strain. Sudden cardiac events are the leading cause of duty-related death in the fire service. This cross-sectional study examined cardiometabolic measures and prevalence of risk factors in firefighters by age and sex and compare these data to the general population.

Hypertension in the United States Fire Service.

Hypertension is a major risk factor for atherosclerotic cardiovascular disease and cardiac remodeling and is associated with an increased risk of sudden cardiac events, the leading cause of duty-related death in the fire service. We assessed systemic blood pressures and prevalence of hypertension among US firefighters by decade of life. Medical records of career firefighters (5063 males and 274 females) from four geographically diverse occupational health clinics were assessed.

Cardiovascular Disease Risk Factors by BMI and Age in United States Firefighters.

Objective: This study examined cardiovascular disease risk factors by BMI category in firefighters, the association of BMI and age with risk factor prevalence, and the prevalence of risk factors by BMI category within age groups.

Methods: Cardiovascular measures from the medical evaluations of 4,453 firefighters, performed between 2015 and 2018 at four occupational health clinics in the United States (South-West Cohort, Mid-Atlantic Cohort, South-East Cohort, and Mid-West Cohort), were analyzed cross-sectionally by BMI and age categories.

Results: Among female firefighters with normal weight, 25% had high blood pressure, 8% had low high-density lipoprotein cholesterol, and 0% had high glucose, whereas the prevalence in female firefighters with obesity was 57%, 45%, and 11%, respectively.

Pre-Sleep Low Glycemic Index Modified Starch Does Not Improve Next-Morning Fuel Selection or Running Performance in Male and Female Endurance Athletes.

To determine the effects of pre-sleep supplementation with a novel low glycemic index (LGI) carbohydrate (CHO) on next-morning substrate utilization, gastrointestinal distress (GID), and endurance running performance (5-km time-trial, TT). Using a double-blind, randomized, placebo (PLA) controlled, crossover design, trained participants ( = 14; 28 ± 9 years, 8/6 male/female, 55 ± 7 mL/kg/min) consumed a LGI, high glycemic index (HGI), or 0 kcal PLA supplement ≥ 2 h after their last meal and <30 min prior to sleep. Upon arrival, resting energy expenditure (REE), substrate utilization, blood glucose, satiety, and GID were assessed.

Changes in Firefighter Weight and Cardiovascular Disease Risk Factors over Five Years.

Purpose: This study aimed to assess changes in cardiovascular disease (CVD) risk factors in firefighters who lost, maintained, or gained weight over 5 yr.

Methods: Anthropometrics and biomarkers of CVD were measured during two occupational medical exams 4.8 yr apart in 656 career firefighters.
