Key result
High-risk coffee consumption is linked to ~16-fold higher hypertension odds in rotating-shift workers.
Why the study?
Rotating-shift manufacturing workers face heightened vulnerability to hypertension from circadian disruption and unhealthy lifestyles, yet tailored workplace preventive interventions remain scarce in South Kalimantan, Indonesia, where hypertension prevalence exceeds the national average.
What lifestyle factors are associated with hypertension among rotating-shift manufacturing workers, and is an educational pocket book an acceptable promotive-preventive intervention in this population?
Cross-Sectional (n=123)
What lifestyle factors are associated with hypertension among rotating-shift manufacturing workers, and is an educational pocket book an acceptable promotive-preventive intervention in this population?
Coffee consumption, occupational stress, and tobacco smoke exposure are strongly associated with hypertension in rotating-shift manufacturing workers, and a tailored educational pocket book shows high acceptability for workplace health promotion.

May inform targeted assessments among rotating-shift workers; hypothesis-generating for preventive interventions.
Background: Rotating-shift manufacturing workers experience heightened vulnerability due to circadian disruption and unhealthy lifestyles. Although hypertension prevalence in South Kalimantan, Indonesia, exceeds the national average, workplace preventive interventions tailored for shift workers remain scarce. This study aimed to identify lifestyle factors associated with hypertension among rotating-shift manufacturing workers and to develop an educational pocket book as a promotive-preventive intervention.Methods: This two-phase study comprised a cross-sectional survey of 123 rotating-shift workers, analyzing lifestyle variables and blood pressure using logistic regression. Phase 2 developed a hypertension pocket book using a simplified ADDIE model and conducted a formative evaluation of its acceptability and perceived usability among 55 workers who had read it.Result: Hypertension prevalence was 39.0%. Multivariate analysis identified high-risk coffee consumption (OR=16.046; 95% CI: 3.157-81.555), stress (OR=11.131; 95% CI: 2.591-47.823), and tobacco smoke exposure (OR=7.674; 95% CI: 2.331-25.263) as the primary factors associated with hypertension (p<0.001), explaining 54.9% of the variance. Notably, the wide confidence intervals for these odds ratios warrant cautious interpretation given the cross-sectional design. The developed pocket book achieved a 98.2% positive perception rate, with 100% finding it comprehensible and 89.1% intending to apply its guidelines.Conclusion: Coffee consumption, occupational stress, and tobacco smoke exposure are the primary factors strongly associated with hypertension among rotating-shift workers. The educational pocket book demonstrated high acceptability. Companies should integrate this medium into occupational health programs, supported by continuous mentoring and policies facilitating healthy lifestyle adoption.

Nurbaiti et al. (2026) conducted a cross-sectional in Hypertension (n=123). High-risk coffee consumption vs. Low/no high-risk coffee consumption was evaluated on Hypertension (OR 16.046, 95% CI 3.157-81.555, p=<0.001). High-risk coffee consumption (OR 16.046), occupational stress (OR 11.131), and tobacco smoke exposure (OR 7.674) were significantly associated with hypertension in rotating-shift workers (p<0.001).
