Fostering cardiovascular health at work - case study from Senegal.

Background: Of the 15 million annual premature deaths from non-communicable diseases (NCDs), 85% occur in low- and middle-income countries (LMICs). Affecting individuals in the prime of their lives, NCDs impose severe economic damage to economies and businesses, owing to the high mortality and morbidity within the workforce. The Novartis Foundation urban health initiative, Better Hearts Better Cities, was designed to improve cardiovascular health in Dakar, Senegal through a combination of interventions including a workplace health program. In this study, we describe the labor policy environment in Senegal and the outcomes of a Novartis Foundation-supported multisector workplace health coalition bringing together volunteering private companies.

Methods: A mixed method design was applied between April 2018 and February 2020 to evaluate the workplace health program as a case study. Qualitative methods included a desk review of documents relevant to the Senegalese employment context and work environment and in-depth interviews with eight key informants including human resource representatives and physicians working in the participating companies. Quantitative methods involved an analysis of workplace health program indicators, including data on diagnosis, treatment and control of hypertension in employees, provided by the coalition companies, and a cost estimate of NCD-related ill-health as compared to the investment needed for hypertension screening and awareness raising events.

Results: Senegal has a legal and regulatory system that ensures employee protection, supports social security benefits, and promotes health and hygiene in companies. The Dakar Workplace Health Coalition comprised 18 companies, with a range of staff between 300 and 4'220, covering 36'268 employees in total. Interviews suggested that the main enablers for workplace program success were strong leadership support within the company and a central coordination mechanism for the program. The main barrier to monitor progress and outcomes was the reluctance of companies to share data. Four companies provided aggregated anonymized cohort data, documenting a total of 21'392 hypertension screenings and an increasing trend in blood pressure control (from 34% in Q4 2018 to 39% in Q2 2019) in employees who received antihypertensive treatment.

Conclusion: Evidence on workplace health and wellness programs in Africa is scarce. This study highlights how private sector companies can play a significant role in improving cardiovascular population health in LMICs.
