Stopping tuberculosis: a biosocial model for sustainable development

Area of Science:

• Public Health
• Social Medicine
• Global Health

Background:

• Tuberculosis (TB) transmission and progression are significantly influenced by social determinants like poor living conditions and nutrition.
• Historically, improved living standards and social interventions reduced TB burden before the advent of chemotherapy.
• Current TB management is predominantly biomedical, with recent funding yielding progress in mortality but limited success in reducing incidence.

Purpose of the Study:

• To highlight the need for integrating social approaches with biomedical strategies to combat the global tuberculosis burden.
• To emphasize the importance of a biosocial model for sustainable development and poverty alleviation.
• To advocate for multisectoral coordination and community participation in TB control efforts.

Main Methods:

• Review of historical and current trends in tuberculosis management and control.
• Analysis of the impact of social factors on tuberculosis incidence and mortality.
• Conceptual framework development for a biosocial approach to tuberculosis.

Main Results:

• While biomedical interventions have reduced TB mortality, incidence remains a significant challenge, particularly in vulnerable populations.
• Reintroducing and strengthening social approaches, alongside biomedical advancements, is essential for accelerated progress.
• A biosocial approach, integrating health, social, economic, and environmental actions, is proposed as a comprehensive strategy.

Conclusions:

• Ending tuberculosis requires a paradigm shift from purely biomedical interventions to a comprehensive biosocial approach.
• Multisectoral collaboration and the active involvement of affected communities are vital for success.
• Implementing a biosocial strategy can significantly reduce TB morbidity and mortality while contributing to poverty reduction and sustainable development.
