Prevention of Coronary Heart Disease in Morbidly Obese Patients (SphCor)

This study is ongoing, but not recruiting participants.

Oslo University Hospital
Information provided by (Responsible Party):
Jøran Hjelmesæth, The Hospital of Vestfold
ClinicalTrials.gov Identifier:
NCT00626964
First received: February 20, 2008
Last updated: May 11, 2017
Last verified: May 2017
  Purpose
The changes in risks of developing coronary heart disease in patients with morbid obesity after different weight loss interventions have not been extensively studied. The primary objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitering) is comparable with a 7-week low-energy-diet followed by bariatric surgery in decreasing the risk of cardiovascular disease in these patients.

Condition Intervention

Study Type: Observational
Study Design: Observational Model: Other

Enrollment: 200
Study Start Date: February 2008
Estimated Study Completion Date: December 2020
Estimated Primary Completion Date: December 2020 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Lifestyle or bariatric surgery
Morbid Obesity with BMI >= 40 kg/m2 or BMI >= 35 with Comorbidity
Procedure: Bariatric Surgery
Bariatric Surgery Treatment: Duodenal Switch, Gastric Sleeve or Gastric bypass.
Behavioral: Conservative Treatment:
Intensive Lifestyle Intervention Program
Other Name: Conservative

Detailed Description:

Patients matching the eligibility criteria were divided into two groups (not randomized). One group underwent a 7 weeks Low-Energy-Diet before bariatric surgery, the other group participated in an intensive lifestyle intervention program for 3 months.

Data on arterial stiffness, body weight, body composition, blood pressure, blood samples, vital parameters are registered in the both groups at baseline, 7 weeks and after 1 year.
