The recent Perspective article in JAMA raises a deeply unsettling argument. The problem facing population health is no longer simply neglect. It is the growing possibility that policy decisions themselves are beginning to work against health.
The authors describe how, over the past decade, the United States has already experienced stagnation and even decline in key health indicators such as life expectancy. This was not unexpected. For years, public health experts had pointed to the structural determinants that shape health outcomes, including access to healthcare, socioeconomic inequality, education, environmental exposures, and the strength of public health institutions.
The solutions were not unknown. Expand access to care. Strengthen social protection. Regulate harmful industries. Invest in science and public health systems. Address inequality. These are long-established principles supported by evidence.
What is new, and concerning, is the shift away from these solutions. The article argues that recent policy directions have not merely failed to improve population health but may actively undermine it. Reductions in support for scientific research weaken the evidence base that informs policy. Erosion of public health protections reduces the ability to prevent harm before it occurs. Policies that increase social and economic vulnerability widen health inequities.
In this framing, worsening population health is no longer an unintended consequence. It becomes predictable. When policies disregard the foundations of health, outcomes follow accordingly.
This perspective invites reflection beyond the United States.
In Malaysia, several structural signals warrant attention.
First, the burden of disease is already high. Malaysia has one of the highest prevalences of obesity in Asia, accompanied by a growing burden of non-communicable diseases. This reflects sustained exposure to behavioural and environmental risks, particularly dietary patterns that are deeply embedded in daily life.
Second, the healthcare system is under strain. Workforce challenges, including shortages, migration, and burnout, are increasingly evident. A constrained workforce limits the system’s ability to balance curative services with preventive and public health functions, shifting focus towards short-term demand rather than long-term health outcomes.
Third, there are gaps in policy and enforcement related to known health risks. Tobacco control, including the regulation of e-cigarettes, remains an area of concern. Reluctance to implement and enforce stronger measures risks sustaining nicotine dependence and enabling new patterns such as dual use, particularly among younger populations.
These are not isolated issues. They represent interconnected elements within the broader population health landscape.
The concern is not that Malaysia is currently adopting policies that directly undermine health. Rather, it is the possibility that, without decisive and sustained action, existing conditions, cultural norms, and policy hesitations may collectively produce similar effects.
The lesson from the JAMA article is clear. Population health is shaped by policy choices. When health is not consistently prioritised across sectors, deterioration becomes a foreseeable outcome rather than an unexpected one.
Malaysia remains at a point where the trajectory can still be shaped. Recognising these signals early allows for a more deliberate response, ensuring that population health remains central in policy and practice, rather than becoming an afterthought.
