Insights
Gastric bypass surgery significantly reduces weight and improves cardiometabolic risk factors in Hispanic adults. These positive outcomes, including weight loss and reduced disease risks, vary between genders one year post-operation.
Area of Science:
- Bariatric Surgery
- Cardiovascular Health
- Obesity Medicine
Background:
- Morbid obesity presents significant health challenges and costs, disproportionately affecting ethnic minorities.
- Limited data exists on the long-term effectiveness of bariatric surgery for weight and chronic disease risk reduction in Hispanic populations.
Purpose of the Study:
- To evaluate the effectiveness of gastric bypass surgery in reducing weight and cardiometabolic disease risk factors among Hispanic adults.
- To analyze gender-specific differences in surgical outcomes.
Main Methods:
- Retrospective analysis of 633 Hispanic adults undergoing gastric bypass surgery (2002-2010).
- Comparative analysis of weight, BMI, and cardiometabolic risk factors (blood pressure, glucose, lipids) pre-surgery and 1 year post-surgery.
Main Results:
- Significant reductions in mean weight and BMI were observed 1 year after surgery.
- Improvements in systolic blood pressure, diastolic blood pressure, fasting plasma glucose, HbA1c, HDL, LDL, and triglycerides.
- Gender-based differences in outcomes: males showed greater weight loss and improvements in HbA1c, HDL, and triglycerides; females had greater LDL reduction.
Conclusions:
- Gastric bypass surgery is effective for significant weight loss and cardiometabolic risk reduction in Hispanic adults.
- Observed improvements in health markers vary by gender.
- This surgical approach is a viable option for Hispanic adults (excluding Mexican Americans) seeking weight management and chronic disease risk mitigation.
Background:
The increasing prevalence of US morbid obesity is associated with serious health consequences and high medical costs, particularly among ethnic minority groups. Little information is available on the long-term weight and chronic disease risk reduction effectiveness of bariatric surgery among Hispanics.
Methods:
A retrospective medical chart analysis of 633 Hispanic adults (76% female, mean age at surgery 41.3 years) from Central and South America and the Caribbean who underwent gastric bypass surgery from 2002 to 2010 was conducted. A presurgery and 1-year postsurgery comparative means analysis of weight, body mass index (BMI), and cardiometabolic disease risk factors [systolic (SBP) and diastolic blood pressure (DBP), fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TGs) was performed.
Results:
Mean weight (127-109 kg) and BMI (46.4-39.9 kg/m(2)) significantly decreased and all cardiometabolic disease risk factors improved from before to 1 year after surgery. Males were significantly more likely than females to show postsurgery improvement in weight (-21.7 kg versus -16.9 kg, P<0.0001), HbA1c (-1.1% versus -0.7%, P=0.02), HDL (3.2 mg/dL versus -0.6 mg/dL, P=0.04), and TGs (-97.2 mg/dL versus -54.5 mg/dL, P=0.006) versus females. Conversely, women were significantly more likely than men to have postsurgery improvements in LDL (-24.5 mg/dL versus -12.7 mg/dL, P=0.04).
Conclusions:
Gastric bypass surgery results in significant weight loss and cardiometabolic disease risk reduction among Hispanic adults 1 year after surgery. These improvements vary by gender. Gastric bypass surgery is an effective treatment option for weight loss and chronic disease risk improvements in Hispanic adults who are not Mexican American.
