AI Article Synopsis
- Long working hours have been linked to a higher risk of cardiovascular disease, and this study explores how they affect dietary choices, particularly sodium intake, which is a risk factor for hypertension.
- Using data from the Korea National Health and Nutrition Examination Survey (2013-2020), the study found that 83.7% of wage workers exceeded the recommended daily sodium intake, with males working 41-52 hours and over 52 hours showing significant correlations with increased sodium consumption.
- Conclusions suggest that longer hours lead to less time for home-cooked meals, pushing workers towards fast food and eating out, highlighting the need for workplace interventions focused on healthier eating habits.
Article Abstract
Background: Long working hours are associated with an increased risk of cardiovascular disease, yet the underlying mechanism(s) remain unclear. The study examines how occupational factors like working hours, shift work, and employment status correlate with dietary choices and sodium intake, impacting hypertension risk.
Methods: This study used data from the Korea National Health and Nutrition Examination Survey conducted between 2013 and 2020. The dataset included 8,471 respondents, all of whom were wage workers aged 20 or older and reported working at least 36 hours per week. Individuals who have been previously diagnosed with or are currently diagnosed with hypertension, diabetes, or dyslipidemia were excluded. The average daily sodium intake was assessed via a 24-hour dietary recall method. Average weekly working hours were categorized into 3 groups: 36-40 hours, 41-52 hours, and over 52 hours. Multiple logistic regression models were used.
Results: Study findings revealed that 83.7% of participants exceeded the recommended daily sodium intake of 2 g set by the World Health Organization. After adjusting for confounding factors, a positive correlation was observed between average working hours and daily sodium intake. Among males, statistical significance was found in the group with average weekly working hours of 41-52 hours (prevalence ratio [PR]: 1.17; 95% confidence interval [CI]: 1.05-1.30) and the group exceeding 52 hours (PR: 1.22; 95% CI: 1.09-1.38) when comparing the fourth quartile of daily sodium intake to the combined quartiles of Q1, Q2, and Q3. Among females, no significance was noted.
Conclusions: Long working hours were associated with increased sodium intake, primarily among male workers. This connection is likely attributed to having less time for home-cooked meals, resulting in higher fast food consumption and dining out. A workplace intervention promoting healthy eating and reducing stress is essential to lower sodium consumption and mitigate hypertension risk.

Background: Sleep deprivation leads to an increase in oxidative stress and activation of inflammatory response and both could increase the production and accumulation of toxic beta-amyloid in the hippocampus which is considered one of the molecular drivers of Alzheimer's pathogenesis and progression. Despite these findings, obtaining sleep is still challenging in our modern society that values work around the clock. Omega-3 fatty acids represents an active biological agent with vital antioxidant and anti-inflammatory activities that could protect memory in the face of insufficient sleep.
