INTRO Cardiovascular Risk Factors Among Maine's Logging Workforce Health Screening Results from Maine Loggers' Health and Safety Study



Cardiovascular Risk Factors Among Maine’s Logging Workforce Background Despite technology and mechanization reducing some workplace hazards, logging is still one of the most dangerous civilian occupations in the United States. Less is known about their overall health status as evidence about health has mostly been gathered through surveys and questionnaires. Objective(s) This research reports on in-person physical health assessments and self-reported health data collected among Maine logging workers, as part of a larger longitudinal study. Methods Health assessments, completed with a sub-cohort from the overall study, were conducted at pop-up clinics in logging locations around the State of Maine in Spring 2019. Data about physical health measures included a physical exam, vitals, cholesterol and glucose testing, audiometry screening, vision, and carbon monoxide screening. In addition, loggers completed a health questionnaire, which included questions about their own health as well as family health history. Results The majority of the 75 logging health assessment participants were men (97.1%) with a median age of 46, and a mean BMI of 30.6 kg/m2 (SD 4.9). More than 90% of them had elevated blood pressure, with over 30% at stage I hypertension and nearly half at stage II hypertension (45.9%). More than a third (38.4%) presented at least a single joint abnormality. About half of the loggers presented high-frequency hearing loss (left 53.5%, right 42.3%). Conclusion Cardiovascular and musculoskeletal risk factors among loggers should be addressed in future research interventions.
While logging is known to be one of the most
dangerous civilian occupations, less is known
about the impact of work mechanization on
chronic disease risk factors of loggers. This
study reports cardiovascular disease (CVD)
risk factors among Maine loggers.
Physical health assessments
and surveys collected at:
Logging company garages
(4 locations)
Logger Trade Show
Sample size was impacted by cancellation of data
collection due to the pandemic
“White coat syndrome” may have impacted blood
pressure measurements.
Cholesterol and glucose levels were good
Need to assess noise exposure at work as a
possible effect for hypertension
Need to analyze body fat percentage for providing
a better picture for health than BMI
The industry needs to keep their workers healthy
and attract the new generations

Mallampati scores are significantly
associated with higher BMI (p=0.0038) and
age (p=0.0045)
Significant difference in BMI across the four
levels of hypertension (omnibus p=0.0103)
Significant difference (p=0.04) in BMI
