Lifestyle decreases risk factors for cardiovascular diseases

Area of Science:

• Cardiovascular Health
• Preventive Medicine
• Lifestyle Medicine

Background:

• Cardiovascular diseases (CVD) pose a high morbidity and mortality burden in developed nations.
• Lifestyle modifications offer a potential 50% reduction in CVD incidence.
• Understanding the impact of structured lifestyle interventions on CVD risk factors is crucial.

Purpose of the Study:

• To evaluate the effect of a one-week "NEW START" rehabilitative retreat on key cardiovascular disease risk factors.
• To measure changes in body weight, BMI, blood pressure, heart rate, serum cholesterol, and blood glucose.
• To assess the impact of a controlled low-fat, low-energy, lacto-ovo-vegetarian diet and exercise program in a stress-free environment.

Main Methods:

• A cohort of 1349 volunteers (320 men, 1029 women, mean age 51) participated in 30 rehabilitative retreats.
• Participants followed a low-fat, low-energy, lacto-ovo-vegetarian diet combined with exercise in a stress-free setting.
• Measurements included body weight, BMI, blood pressure, heart rate, serum cholesterol, and blood glucose before and after the one-week retreat.

Main Results:

• Significant reductions were observed in body weight (p<0.0001), BMI (p<0.0001), systolic blood pressure (p<0.0001), diastolic blood pressure (p<0.0001), serum cholesterol (p<0.0001), and blood glucose (p<0.0001).
• Heart rate did not show a significant decrease.
• Lacto-ovo vegetarians and Seventh-day Adventists exhibited lower risk factor parameters compared to controls.

Conclusions:

• A one-week intervention incorporating a low-fat, low-energy diet and exercise in a stress-free environment positively impacts cardiovascular disease risk factors.
• The "NEW START" retreat demonstrates a significant, short-term improvement in modifiable CVD risk factors.
• Sustained positive effects were suggested by non-significant changes one year post-retreat in a smaller sample.
