Summary
Shift work tolerance in oil rig workers was not significantly affected by age or years of exposure. However, swing shift workers reported longer sleep duration, with age impacting sleep differently based on shift type.
Area of Science:
- Occupational Health
- Sleep Science
- Chronobiology
Background:
- Shift work is linked to sleep and health issues, with tolerance potentially decreasing with age.
- Understanding shift work tolerance across diverse populations is crucial.
- Previous research suggests age impacts shift work tolerance, necessitating further investigation.
Purpose of the Study:
- To investigate the relationship between age, shift work exposure, shift type, and sleep/health problems.
- To examine morningness as a factor in shift work tolerance.
- To analyze these factors specifically within the oil rig shift worker population.
Main Methods:
- A total of 199 oil rig workers participated in the study.
- Participants were assigned to either 12-h day shifts or swing shifts (alternating day and night shifts).
- Data on demographics, work, sleep, and health were collected via questionnaires.
Main Results:
- No significant associations were found between age or years of shift work exposure and sleep/health parameters.
- Swing shift workers reported longer sleep duration compared to day shift workers.
- A significant interaction between age and shift type affected sleep duration; it decreased with age in swing shift workers but increased with age in day shift workers.
Conclusions:
- Older workers may exhibit good tolerance to shift work, contrary to some expectations.
- Age, duration of shift work, and shift type did not appear to significantly impact tolerance in this specific group.
- Potential healthy worker effect or selection bias may influence these findings, suggesting cautious interpretation.

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
01:24Factors Affecting Workability
The workability of concrete is a critical characteristic that influences the ease of mixing, handling, and finishing the concrete. It is affected by several factors including water content, aggregate properties, and admixtures like air entrainment. Water plays a fundamental role as it lubricates the concrete mix, facilitating easier movement and placement. However, the water requirement varies depending on the texture and shape of aggregates. Finer particles and angular, rough-textured...
01:28Survey Safety
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
