A group of 318 obese patients followed-up at the Obesity Unit in Prague in 1995-1997 was included into a study. Their treatment was based on the standard combination of a weight reduction diet, physical activity and behavioural intervention.
In patients with more severe degrees of óbesity VLCD in one daily portion, pharmacotherapy, in-patient regimen lasting 24 days, including VLCD (1,500 kJ/day), exercise and group psychotherapy; or bariatric surgery (mostly laparoscopic gastric banding) were used, if necessary. Patients were divided into two groups according to their compliance to the weight reducing regimen.
Group A dropped out before 2 years of follow-up, group B was followed-up 2 years or more. The groups did not differ significantly in their mean age, initial body weight, initial BMI and fat content and in percentage of males and females.
Weight, BMI, fat content, essential anthropometric indices (waist circumference, WHR, subscapular and triceps skinfolds) and blood pressure are presented in this study. The maximum weight loss was significantly higher in group B.
We did not find any other significant differences between group A and group B. The most significant predictor of compliance expressed as duration of follow-up (evaluated by multiple regression with stepwise variable selection) was the maximum BMI decrease (p < 0.005).
The most significant predictors of the weight loss at the end of the follow-up were maximum weight loss and maximum decrease of BMI (p < 0.001). Family history of obesity (obese one or both parents) was significantly more often in group B (p < 0.05).
This trend was expressed predominantly in females (p < 0.01), where also family history of obesity in mother was significantly more often in group B (p < 0.05). The frequency of methods used in individual patients was estimated.
Standard combination of diet, enhanced physical activity and behavioural intervention was used in all patients. All other methods were used significantly more frequently in group B.
In group A in-patient treatment was significantly more often used in men. The in-patient treatment promotes the compliance with the therapeutic regimen in women significantly more effectively than in men.
