Key result

Prehypertension and hypertension affect ~35% of freshmen, linked to male sex, alcohol, and obesity.

  • aPR 3.07
  • 95% CI 2.32-4.06
  • P<0.001
  • n=840

Why the study?

Prehypertension and hypertension in young adults are key risk factors for later cardiovascular disease, but data on their burden and risk factors among Vietnamese youth are lacking.

Population

840 freshmen randomly sampled from Vietnam National University, Hanoi

Design

Cross-sectional study

Implication

High prehypertension burden in Vietnamese freshmen supports targeted screening; leaves open whether early interventions alter long-term outcomes.

Population
840 freshman students (394 males, 446 females) from Vietnam National University, Hanoi, aged ≥18 years without severe chronic illnesses, cancer, or prior cardiovascular diseases.

Outcome
Prevalence of prehypertension (systolic BP 120-139 mmHg or diastolic BP 80-89 mmHg) and hypertension (BP ≥140/90 mmHg or on antihypertensives)surrogate

Main Result

Effect estimate: aPR 3.07 (95% CI 2.32-4.06)

Absolute Event Rate: 56.6% vs 15.7%

p-value: p=<0.001

There is a high burden of prehypertension among Vietnamese university freshmen, strongly associated with male sex, alcohol consumption, and obesity, highlighting the need for early lifestyle interventions.

Limitations

  • Cross-sectional design failed to establish causal relationships between risk factors and the development of prehypertension and hypertension
  • Self-reported data for lifestyle factors may be subject to recall bias or underreporting
  • Lack of data on homocysteine levels, blood lipid, and blood glucose
  • Limited generalizability due to the university setting and potential socioeconomic differences compared to the broader non-university young population
  • Cross-sectional design cannot establish causality
  • Self-reported data subject to recall bias
  • Lack of data on homocysteine levels, blood lipids, and blood glucose
  • University setting may limit generalizability due to socioeconomic status differences compared to the broader non-university young population

Vo et al. (2023) conducted a cross-sectional in Prehypertension and hypertension (n=840). Male sex vs. Female sex was evaluated on High blood pressure (prehypertension or hypertension) (aPR 3.07, 95% CI 2.32-4.06, p=<0.001). Among university freshmen in Vietnam, the prevalence of prehypertension and hypertension was 33.5% and 1.4%, with male sex, alcohol consumption, and obesity identified as independent risk factors.
