Insights
Young adults with isolated systolic hypertension receive diagnoses and treatments less often than those with combined or isolated diastolic hypertension. This disparity may impact hypertension control in this age group.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Hypertension (HTN) control remains a challenge in young adults.
- Differential diagnosis and treatment rates based on HTN type may underlie poor control.
- Understanding these disparities is crucial for improving hypertension management in younger populations.
Purpose of the Study:
- To compare the rates of hypertension diagnosis and antihypertensive medication initiation among young adults with isolated systolic, isolated diastolic, and combined systolic/diastolic hypertension.
- To identify potential disparities in care based on hypertension subtype in patients aged 18 to 39 years.
Main Methods:
- Retrospective analysis of 3003 patients aged 18 to 39 years with incident hypertension.
- Kaplan-Meier survival analysis and Cox proportional hazards models were used to compare diagnosis and treatment rates across hypertension subtypes.
- Hazard ratios (HR) and 95% confidence intervals (CI) were calculated to quantify differences.
Main Results:
- Only 56% of young adults with isolated systolic HTN received a diagnosis, compared to 63% with combined HTN.
- Antihypertensive medication initiation was observed in 32% of isolated systolic HTN cases versus 52% of combined HTN cases.
- Patients with isolated systolic HTN had a 50% slower diagnosis rate (HR: 0.50) and 58% slower medication initiation (HR: 0.42) compared to those with combined HTN.
Conclusions:
- Young adults with isolated systolic hypertension experience significantly lower rates of diagnosis and treatment initiation compared to those with combined systolic/diastolic hypertension.
- Similar, though less pronounced, disparities were observed for isolated diastolic hypertension.
- These findings highlight critical gaps in hypertension care for young adults, particularly those with isolated systolic hypertension, necessitating targeted interventions.
Abstract:
Differential rates of diagnosis and treatment by hypertension (HTN) type may contribute to poor HTN control in young adults. The objective of this study was to compare rates of receiving a hypertension diagnosis and antihypertensive agent among young adults with (1) isolated systolic, (2) isolated diastolic, and (3) combined systolic/diastolic HTN. A retrospective analysis was conducted in patients aged 18 to 39 years (n=3003) with incident HTN. Kaplan-Meier survival and Cox proportional hazards analyses were performed. Only 56% with isolated systolic HTN received a diagnosis compared with 63% (systolic/diastolic); 32% with isolated systolic HTN received an initial antihypertensive compared with 52% (systolic/diastolic). Compared with patients with systolic/diastolic HTN, those with isolated systolic HTN had a 50% slower diagnosis rate (hazard ratio [HR], 0.50; 95% confidence interval [CI], 0.41-0.60) and those with isolated diastolic HTN had a 26% slower rate (HR, 0.74; CI, 0.60-0.92). Patients with isolated systolic HTN had 58% slower medication initiation (HR, 0.42; CI, 0.34-0.51) and those with isolated diastolic HTN had 31% slower rates (HR, 0.69; CI, 0.55-0.86). Young adults with isolated systolic HTN have lower diagnosis and treatment rates.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
