Dietary habits and inadequate control of blood pressure in hypertensive adults assisted by a Brazilian Family Doctor Program

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Hypertension (n=239). Intervention: Higher BMI, sodium excretion, and serum creatinine vs. Lower levels of these risk factors. Primary outcome: Inadequate blood pressure control (SBP ≥140 mmHg and/or DBP ≥90 mmHg) (PR 1.027, 95% CI 1.009-1.045, p=0.004).

Key result

Higher BMI (PR 1.027), serum creatinine (PR 1.894), and sodium excretion were significantly associated with inadequate blood pressure control in treated hypertensive adults.

Why the study?

Are specific dietary habits and clinical factors associated with inadequate blood pressure control in treated hypertensive adults?

Population

Male and female hypertensive adults aged ≥20 years adherent to antihypertensive drug treatment assisted by a…

Discussion

Member takes

Implication

Salt intake and BMI were associated with inadequate BP control; hypothesis-generating and should not yet change practice.

Are specific dietary habits and clinical factors associated with inadequate blood pressure control in treated hypertensive adults?

Population

239 hypertensive adults aged 20 years and older, undergoing and adhering to antihypertensive treatment in a Brazilian primary care program.

Exposure

Dietary habits (including meat and salt consumption) and clinical factors (BMI, serum creatinine, skin color)

Outcome

Inadequate blood pressure controlsurrogate

Main Result

Effect estimate: PR 1.027 (95% CI 1.009-1.045)

p-value: p=0.004

In treated hypertensive adults, inadequate blood pressure control is associated with higher BMI, higher serum creatinine, white skin color, and higher salt consumption.

Limitations

Cross-sectional design limits causal inference
Participation rate was approximately 56%, leading to possible selection bias
Missing biochemical data (16.7%)
Reliance on a food frequency questionnaire, which is subject to recall bias and omission of information

Souza et al. (2011) conducted a cross-sectional in Hypertension (n=239). Higher BMI, sodium excretion, and serum creatinine vs. Lower levels of these risk factors was evaluated on Inadequate blood pressure control (SBP ≥140 mmHg and/or DBP ≥90 mmHg) (PR 1.027, 95% CI 1.009-1.045, p=0.004). Higher BMI (PR 1.027), serum creatinine (PR 1.894), and sodium excretion were significantly associated with inadequate blood pressure control in treated hypertensive adults.
