Abstract:
Introduction:Hypertension is common in obesity and increases
cardiovascular risk. Bariatric surgery improves metabolic
health, but subgroup differences in blood pressure response
remain unclear. This study examined 1-year changes in
systolic blood pressure (SBP) and diastolic blood pressure
(DBP) after bariatric surgery across sex, age group, and
diabetes status.
Methodology:This study included 32 obese adults undergoing bariatric
surgery, with blood pressure measured at baseline, 6
and 12 months. Generalized estimating equation models
were used to evaluate changes in SBP and DBP over time,
adjusting for age, sex, surgery type, diabetes category,
baseline body mass index, antihypertensive medication
use, and baseline blood pressure. Interaction terms were
tested to assess differences in blood pressure trajectories
across subgroups.
Results:Participants were predominantly female (67.4%), with a
mean age of 36.9 ± 6.2 years and a mean body mass index
of 40.7 ± 8.8 kg/m². Hypertension and diabetes were present
in 40.6 and 31.3% of participants, respectively. There was a
significant time effect for both SBP (p <0.001) and DBP (p
= 0.004). At 12 months post-surgery, mean SBP decreased
by 15 mmHg and DBP by 7.9 mmHg compared with
baseline (both p <0.001). No significant interactions were
observed between time and sex, diabetes category, or age
category, indicating that blood pressure improvements
were comparable across subgroups.
Conclusion:Bariatric surgery was associated with clinically meaningful
reductions in both SBP and DBP, with similar improvement
patterns observed across demographic and metabolic subgroups. These findings support the effectiveness of bariatric
surgery as a strategy for blood pressure reduction and
cardiovascular risk management in patients with obesity.
