Key result
Hypertension is linked to ~5.9-fold higher odds of moderate-to-severe CVD risk in offshore male workers.
Why the study?
Offshore workers face occupational and lifestyle exposures that may increase CVD risk, yet data on cardiovascular risk profiles among offshore personnel in Malaysia were limited.
Cross-Sectional (n=241)
A high majority (77.7%) of offshore male workers in Peninsular Malaysia have moderate-to-severe cardiovascular disease risk, strongly driven by modifiable occupational and clinical factors including hypertension, high job stress, dyslipidaemia, smoking, and shift work.
May signal elevated CVD risk in Malaysian offshore workers; leaves open need for longitudinal studies before guiding interventions.
INTRODUCTION: Offshore workers are exposed to occupational and lifestyle factors that may increase cardiovascular disease (CVD) risk. Limited data are available regarding cardiovascular risk profiles among offshore personnel in Malaysia. This study aimed to determine the prevalence of cardiovascular disease risk levels and associated factors among offshore male workers in Peninsular Malaysia. MATERIAL AND METHODS: A cross-sectional study was conducted among 241 offshore male workers between January and February 2025. Data were collected using structured questionnaires and clinical assessments, including body mass index, blood pressure, and lipid profiles. Participants were categorized into low, moderate, and severe CVD risk groups using Malaysian CVD risk scoring guidelines. Chi-square tests and binary logistic regression were performed to identify associated factors. RESULTS: Among the participants, 22.4% were classified as low risk, 47.3% as moderate risk, and 30.4% as severe risk. Overall, 77.7% fell within the moderate-to-severe CVD risk categories. Significant predictors of elevated risk included increasing age (OR=1.046, p=0.003), higher BMI (OR=1.094, p=0.001), smoking (OR=3.320, p=0.008), shift work (OR=2.663, p=0.017), high job stress (OR=4.530, p=0.003), hypertension (OR=5.930, p=0.011), and dyslipidaemia (OR=3.860, p=0.011). CONCLUSION: A high prevalence of moderate-to-severe cardiovascular risk was observed among offshore workers. Occupational health interventions, regular screening, and lifestyle modification programs are recommended to reduce cardiovascular risk in this population.

Mustafha et al. (2026) conducted a cross-sectional in Cardiovascular disease risk (n=241). Occupational and lifestyle cardiovascular risk factors (including hypertension, high job stress, dyslipidaemia, smoking, shift work, BMI, and age) vs. Low cardiovascular disease risk / absence of risk factors was evaluated on Moderate-to-severe cardiovascular disease (CVD) risk classification based on Malaysian CVD risk scoring guidelines (OR 5.930 (hypertension), p=0.011). Offshore male workers had a 77.7% prevalence of moderate-to-severe CVD risk, significantly associated with hypertension (OR=5.930, p=0.011), job stress (OR=4.530), and smoking (OR=3.320).
