Occupational stress and fatigue as risk factors for hypertension among employees at PT. Perkebunan Milano, Kebun Sei Daun

Q: What are the key findings of this study?

High work fatigue and stress were significantly associated with higher hypertension prevalence, with 60% of highly fatigued employees having hypertension versus 18.9% of those with low fatigue.

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Hypertension (n=52). Intervention: Work stress and work fatigue vs. Low work stress and low work fatigue. Primary outcome: Incidence of hypertension (p=<0.001).

Q: What does this research mean for the field?

Occupational stress and work fatigue are significantly associated with an increased prevalence of hypertension among plantation employees. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.NEUTRAL.

Q: What question did this study set out to answer?

To evaluate the relationship between occupational stress, work fatigue, and the incidence of hypertension among company employees.

Key result

High work fatigue linked to ~3-fold higher hypertension prevalence vs. low fatigue.

P<0.001
n=52

Why the study?

Workers exposed to work stress and work fatigue are at higher risk of hypertension, but the relationship among employees at PT. Milano Kebun Sei Daun was not determined.

Key Points

To evaluate the relationship between occupational stress, work fatigue, and the incidence of hypertension among company employees.
Conducted a quantitative cross-sectional study using total sampling of all 52 employees at PT. Milano Kebun Sei Daun.
Gathered data through structured questionnaires, observation sheets, and direct blood pressure measurements.
Examined demographic and clinical variables using univariate frequency distributions and bivariate chi-square tests (α=0.05).
Hypertension was identified in 14 of 52 employees (26.9%), while 38 respondents (73.1%) had normal blood pressure.
Work stress was significantly associated with hypertension (p=0.044), affecting 2 of 5 individuals (40.0%) with high stress, 6 of 16 (37.5%) with moderate stress, and 6 of 31 (19.4%) with low stress.
Work fatigue was significantly associated with hypertension (p<0.001), occurring in 3 of 5 workers (60.0%) with high fatigue, 4 of 10 (40.0%) with moderate fatigue, and 7 of 37 (18.9%) with low fatigue.

Structured PICO

P

Population

52 adult employees at a plantation company in North Sumatra, consisting of 61.5% males, assessed cross-sectionally for the association between occupational stress, fatigue, and hypertension.

O

Outcome

Incidence of hypertension (defined as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg based on direct measurement)surrogate

Main Result

Absolute Event Rate: 60% vs 18.9%

p-value: p=<0.001

High levels of occupational stress and fatigue are significantly associated with an increased prevalence of hypertension among plantation employees, highlighting the need for workplace stress and fatigue management interventions.

Limitations

Cross-sectional design precludes causal inference, as associations may be bidirectional
Data on work stress and fatigue relied on self-reported questionnaires, subject to recall and social desirability bias
Small sample size (n=52) and single workplace setting limit generalizability to other populations
Did not assess potential confounders such as diet, physical activity, family history, or medication use
Cross-sectional design precludes causal inference (associations may be bidirectional)
Reliance on self-reported questionnaires for work stress and fatigue (subject to recall and social desirability bias)
Small sample size (n=52)
Single workplace setting limits generalizability to other populations

Implication

Occupational fatigue and stress screening may identify at-risk employees; leaves open causal links and preventive efficacy in prospective trials.

Abstract

Background: Hypertension is a major public health problem with increasing prevalence and is a primary risk factor for various cardiovascular diseases. Workers exposed to work stress and work fatigue are at higher risk. This study aimed to determine the relationship between work stress and work fatigue with the incidence of hypertension among employees at PT. Milano Kebun Sei Daun. Method: This quantitative study used a cross-sectional design. The population comprised all 52 employees, and total sampling was used to include all as respondents. Data were collected using questionnaires, observation sheets, and blood pressure measurements. Univariate analysis described frequency distributions, and bivariate analysis used the chi-square test (α=0.05). Results: The study found that 14 respondents (26.9%) had hypertension. Among those with high work stress, 2 had hypertension; among those with high work fatigue, 3 had hypertension. Chi-square tests showed significant associations between work stress and hypertension (p=0.044) and between work fatigue and hypertension (p<0.001). Conclusion: There are significant relationships between work stress and work fatigue with the incidence of hypertension among employees at PT. Milano Kebun Sei Daun. Workplace interventions to reduce stress and fatigue are recommended.
