Reducing Health Risk Factors in Workplaces of Low and Middle-Income Countries

Area of Science:

• Global Health
• Occupational Health
• Public Health Interventions

Background:

• Low- and middle-income countries face significant challenges in managing non-communicable disease risk factors.
• Workplace settings present a unique opportunity for implementing health promotion programs.
• The Community Interventions for Health program aimed to address key health risks in diverse workplaces.

Purpose of the Study:

• To evaluate the impact of workplace interventions on reducing risk factors in China, India, and Mexico.
• To assess changes in tobacco use, physical activity, and dietary habits among workers.
• To determine the effectiveness of culturally adapted health promotion strategies.

Main Methods:

• A non-randomized, controlled study involving 45 industrial, 82 health, and 101 school workplace settings.
• Interventions focused on reducing tobacco use, increasing physical activity, and improving dietary intake.
• Two cross-sectional surveys were conducted at baseline and after 18-24 months.

Main Results:

• Significant reductions in tobacco use prevalence were observed in men (-6.0%, p < .001).
• A significant increase in the proportion of workers consuming five daily portions of fruits and vegetables was noted (+6.9%, p < .001).
• No significant changes were found in physical activity levels or the prevalence of overweight.

Conclusions:

• Workplace interventions demonstrated effectiveness in improving specific health risk factors in the studied populations.
• The findings support the implementation of targeted health programs within occupational settings in low- and middle-income countries.
• Culturally appropriate strategies are crucial for successful health behavior change in diverse workplace environments.
