The Case for 130/80
Hypertension — defined as blood pressure persistently at or above 140/90 mmHg on at least two separate measurements — is a systemic condition that damages multiple organs, including the blood vessels, heart, kidneys, eyes and brain. It is a pervasive, multifaceted public health challenge with far-reaching consequences. Most deaths linked to hypertension occur not from the condition itself but from its complications, particularly cardiovascular and cerebrovascular events such as stroke.
The global burden is substantial and rising. Between 1990 and 2019, the number of people living with hypertension doubled to an estimated 1.3 billion. By 2023, roughly 1.28 billion adults aged 30 to 70 were affected. Yet awareness remains alarmingly low: nearly half of those with the condition do not know they have it. Untreated or poorly managed hypertension can lead to stroke, heart attack, heart failure, kidney failure and widespread organ damage.
The distribution of the disease is uneven. Globally, prevalence is slightly higher among men (34 percent) than women (32 percent), and rates have declined in high-income countries over the past three decades. By contrast, Africa bears the highest regional prevalence, at 36 percent, compared with 28 percent in the Western Pacific region. The gap is even more pronounced in diagnosis and care: in Africa, only 43 percent of cases are diagnosed and just 27 percent receive treatment, resulting in treatment control rates as low as 12 percent.
Ethiopia reflects these disparities. Cardiovascular deaths attributable to elevated systolic blood pressure account for a significant share of mortality, with a disproportionate burden among women. Nationally, only about 34 percent of people with hypertension are diagnosed, 16 percent receive treatment and a mere 6 percent achieve adequate control — a cascade that underscores systemic gaps in screening, access and continuity of care.
Hypertensive disorders take on added urgency in specific populations, particularly pregnant women. Maternal hypertensive disorders are among the leading causes of maternal mortality in sub-Saharan Africa, including Ethiopia, where they rank second. Surveillance data from the Ethiopian Public Health Institute have consistently identified pregnancy-induced hypertension as a major contributor to maternal deaths. Globally, the burden is increasing: between 1990 and 2019, the prevalence of maternal hypertensive disorders rose by 146 percent. In Ethiopia, a 2020 systematic review estimated a pooled prevalence of 6.8 percent.
The human and economic toll is profound. Hypertension not only strains health systems but also erodes household incomes and national productivity through premature death and chronic disability. Compounding the challenge, clinical guidelines have become more stringent. The American College of Cardiology and the American Heart Association now define hypertension at a lower threshold of 130/80 mmHg, expanding the number of individuals considered at risk and in need of monitoring or treatment.
Taken together, these trends point to a silent crisis that is both preventable and, with the right policies, manageable — yet still insufficiently addressed.
Why, then, should Ethiopia consider lowering the blood-pressure threshold used to define hypertension?
First, the scale of the problem is expanding rapidly. Hypertension is no longer a marginal condition but an increasingly common feature of the country’s disease profile. According to the Ministry of Health’s hospital disease registry for the 2017 Ethiopian fiscal year (2024/25), more than 877,000 cases of hypertension in its various forms were reported nationwide — a figure that almost certainly understates the true burden, given low detection rates.
Second, the underlying risk factors for noncommunicable diseases are widespread and, in many cases, worsening. Findings from the Ethiopian Public Health Institute–Ministry of Health STEPS survey (2024) point to a troubling landscape: tobacco use, though relatively low at 3.8 percent, is rising; alcohol consumption stands at 20.1 percent, with a significant share of heavy drinkers; and khat use has reached 23.4 percent nationally, often coupled with alcohol intake.
Physical inactivity affects nearly one in three adults. Average daily salt consumption — at 9.4 grams — is almost double the World Health Organization’s recommended limit. Diets remain poor in fruits and vegetables, and 10.9 percent of adults are overweight or obese.
Screening gaps are stark: the overwhelming majority of adults have never had their cholesterol measured, and fewer than half of those with elevated blood pressure are diagnosed and treated. These converging risks create a pipeline for sustained increases in hypertension and its complications.
Third, hypertension is already a major driver of premature mortality. In 2019 alone, it was associated with an estimated 627,000 deaths in Ethiopia, underscoring its role as a leading, yet largely preventable, cause of death.
Fourth, the age profile of the disease is shifting downward. Evidence from clinical settings suggests that hypertensive disorders — particularly those related to pregnancy — are increasingly affecting women in their 20’s. This trend amplifies both maternal and neonatal risks and places additional strain on health services. Fifth, the burden is projected to grow. By 2030, noncommunicable diseases, including hypertension, are expected to overtake infectious diseases as the leading causes of illness and death in Ethiopia.
Sixth, the country is navigating multiple, overlapping transitions—epidemiologic, demographic, nutritional and obstetric. These shifts are reshaping patterns of disease and vulnerability. The rise of hypertension, alongside persistent infectious diseases, reflects a system under dual pressure.
Seventh, the health system—particularly in rural areas—remains underprepared to manage chronic conditions and their complications, including maternal hypertensive disorders.
Eighth, pregnant women face compounded risks. The intersection of sex, reproductive age and pregnancy creates a distinct vulnerability to hypertensive disorders. Ninth, hypertension continues to behave as a “silent killer,” progressing without symptoms until severe complications arise. Lowering the diagnostic threshold would bring more individuals into care before irreversible damage occurs.
Finally, Ethiopia has already laid important groundwork. The Ministry of Health has developed strategies and guidelines for the prevention and management of hypertension. Aligning these efforts with a lower diagnostic threshold — 130/80 mmHg, as recommended by major international bodies — would expand the pool of individuals eligible for early intervention. While this would increase the number of diagnosed cases, it would also create an opportunity to prevent progression, avert complications and reduce long-term costs.
The logic is straightforward: earlier identification enables earlier action. Lowering the cutoff would not, on its own, solve the problem. But without it, millions will remain undiagnosed until the disease manifests in its most dangerous forms. Given the escalating prevalence of noncommunicable diseases within the nation, the pertinent inquiry is not whether Ethiopia can accommodate a reduced threshold, but rather whether it can sustain the consequences of not doing so.
