Complex relation among Health Belief Model components in TB prevention and care

Area of Science:

• Public Health
• Health Behavior Research
• Epidemiology

Background:

• Tuberculosis (TB) remains a significant global health challenge, particularly among vulnerable populations.
• Understanding the psychological and behavioral factors influencing TB prevention and care-seeking is crucial for effective public health interventions.

Purpose of the Study:

• To investigate the relationships between components of the Health Belief Model (HBM) and tuberculosis (TB) preventive behaviors.
• To examine the association between HBM components and the intention to seek TB care among migrant workers.

Main Methods:

• A cross-sectional study was conducted with 1154 rural-to-urban migrant workers (18-50 years) in China.
• Data were collected through individual, face-to-face interviews using a standardized questionnaire.
• Path analysis using Lisrel 8.7 was employed to examine the relationships among variables.

Main Results:

• Knowledge and perceived benefits components of the HBM predicted TB preventive behaviors (e.g., covering coughs) and seeking TB care.
• Perceived susceptibility and severity also predicted the intention to seek TB care.
• Knowledge of TB positively influenced perceived susceptibility and severity, which in turn predicted perceived benefits.

Conclusions:

• A significant pathway exists from knowledge, through perceived susceptibility and severity, to perceived benefits, ultimately influencing preventive behaviors and TB care-seeking.
• The Health Belief Model provides a valuable framework for understanding and promoting TB prevention and care-seeking behaviors in migrant populations.
