Blood pressure levels impacted by chronic occupational noise exposure

Study found high blood pressure risk increased 10% for each year worked on noisy industrial machinery

2024-08-15
(Press-News.org) Noise exposure is a known occupational hazard in some jobs, particularly for hearing loss, physical and psychological stress, and reduced concentration. A new study presented at the ACC Asia 2024 conference found in adult power loom weavers, chronic noise exposure not only increased their blood pressure overall, but also each year of exposure increased their odds of having high blood pressure by 10%.

“While the mechanism is still not well-explored, it is thought that the stress response by the body to chronic sound exposure causes hormonal imbalances that gradually leads to a permanent elevation of blood pressure,” said Golam Dastageer Prince, MBBS, MPH, medical officer at DGHS Bangladesh and the study’s lead author. “High blood pressure impacts more than a billion people worldwide and just 1 in 5 have it under control, yet it is a major cause of premature death. In addition to treating the high blood pressure through appropriate means, we must find ways to mitigate the exposure to the noise if we want to reduce the cardiovascular risk of these patients.”

Researchers at the Directorate of General Health Services in Bangladesh looked at 289 adult workers in selected weaving factories in the Araihazar sub-district of Narayanganj, Bangladesh, from January to December 2023. Participants took a face-to-face interview to complete a questionnaire covering sociodemographic variables, behavior, dietary habits and family medical history. Blood pressure, height, weight and noise intensity were measured following standard procedures by the researchers.

The study cohort was predominantly male and married and were about 34 years of age on average. According to the researchers, a notable proportion of the cohort was illiterate. Workplace exposure duration averaged nearly 16 years, with noise intensity ranging from 96-111 decibels. In the United States the National Institute for Occupational Safety and Health has established the recommended exposure limits for occupational noise exposures to be 85 decibels on average over an eight-hour workday. Sounds at or below 70 decibels are generally considered safe.   

According to Prince, none of the study population was found to be wearing ear protection personal protective equipment.

“Hopefully we can raise awareness of not only noise-induced hearing loss, but the impact of noise on blood pressure and workers’ behaviors and attitudes towards using personal protective equipment,” Prince said. “Pushing for structural improvements to industries may also help us improve the health safety of these workers.”

The study population had a 31.5% rate of high blood pressure with an additional 53.3% being prehypertensive. The study also found a positive correlation between blood pressure and noise exposure duration. Each year of exposure was found to increase high blood pressure odds by 10%, even after adjusting for age, body mass index and smoking status.

“As the study focused on workers exposed to more than 85 decibels noise for long periods of time, any profession causing workers to experience similar exposure might experience similar blood pressure impacts,” Prince said. “We definitely need more exploratory studies to reveal more information about the potential mechanisms and long-term health outcomes.”

Recent studies have shown that living near noise pollution, including highways, trains and air traffic, can have an impact on cardiovascular health. However, the current study may not apply to noise experienced during daily life. Noise pollution experienced near home typically ebbs and flows, while the industrial exposures in the study are typically continuous in pattern due to the machinery and remain at a constant sound level, according to Prince.

A first-of-its-kind study led by Lawson Health Research Institute is receiving $1.2 million in funding from the federal government, delivered through the Veteran Homelessness Program, to better understand homelessness amongst women in Canada who are military Veterans. “This is an important and yet often invisible problem,” says Dr. Cheryl Forchuk, Lawson Assistant Scientific Director based at St. Joseph’s Health Care London’s Parkwood Institute and the study lead. “This is the first Canadian study to focus exclusively on women Veterans’ experience of homelessness. Gender matters, especially when we’re talking ...

Robot planning tool accounts for human carelessness

2024-08-15
PULLMAN, Wash. -- A new algorithm may make robots safer by making them more aware of human inattentiveness. In computerized simulations of packaging and assembly lines where humans and robots work together, the algorithm developed to account for human carelessness improved safety by about a maximum of 80% and efficiency by about a maximum of 38% compared to existing methods. The work is reported in IEEE Transactions on Systems Man and Cybernetics Systems. “There are a large number of accidents that are happening every day due to carelessness – most of them, unfortunately, from human errors,” said lead ...

Cleaning up the aging brain: Scientists restore brain's trash disposal system

2024-08-15
Alzheimer’s, Parkinson’s, and other neurological disorders can be seen as “dirty brain” diseases, where the brain struggles to clear out harmful waste. Aging is a key risk factor because, as we grow older, our brain's ability to remove toxic buildup slows down. However, new research in mice demonstrates that it’s possible to reverse age-related effects and restore the brain’s waste-clearing process. “This research shows that restoring cervical lymph vessel function can substantially rescue the slower removal of waste from the brain associated with age,” said Douglas Kelley, PhD, a professor of Mechanical ...

Zebrafish use surprising strategy to regrow spinal cord

Zebrafish use surprising strategy to regrow spinal cord
2024-08-15
Zebrafish are members of a rarefied group of vertebrates capable of fully healing a severed spinal cord. A clear understanding of how this regeneration takes place could provide clues toward strategies for healing spinal cord injuries in people. Such injuries can be devastating, causing permanent loss of sensation and movement. A new study from Washington University School of Medicine in St. Louis maps out a detailed atlas of all the cells involved — and how they work together — in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. ...

Bone fracture rates vary dramatically by race

2024-08-15
A new paper in the Journal of Bone and Mineral Research, published by Oxford University Press, finds that bone fracture rates in older women differ by race, quite significantly. While researchers have known for years that the risk of bone fracture is highest for White women, this is the first study to show the real fracture rate for Asian and Hispanic women. Until recently researchers have had limited data on fracture rates by specific race and ethnicity beyond White people, and even less fracture data within race and ethnic groups. Hispanic and Asian populations are the ...
