Weight, body composition and quality of life changes in a Hungarian community-based body weight management program: an observational cohort analysis.

BMI decreased gradually during the 9-month intervention program.

• Mean absolute BMI change was -1.57 kg/m2 (95% CI: -1.81 to -1.32) by the end of the program.
• Baseline BMI was 30.5 kg/m2 [Q1: 28.1; Q3: 32.3].
• 308 subjects were enrolled (281 women, 27 men) aged 18-65 years with BMI 25-35 kg/m2.
• BMI was assessed at baseline and reevaluated at 3, 6, and 9 months.

Body weight was significantly reduced by the end of the 9-month program.

• Mean absolute body weight reduction was -4.30 kg (95% CI: -4.97 to -3.64).
• Participants were adults living with overweight or mild obesity (BMI 25-35 kg/m2).
• The program ran in a Hungarian township community setting between 2015 and 2022.

Body fat percentage decreased significantly over the course of the intervention.

• Body fat percentage decreased by -3.02 percentage points (95% CI: -3.62 to -2.41) by the end of the program.
• Body composition was assessed at baseline, 3, 6, and 9 months.
• The intervention included regular medical, nutritional, and psychological consultations complemented by compulsory individualized physical training.

Quality of life improved significantly during the intervention and improvements were sustained at long-term follow-up.

• The ORWELL-97 (OxR) score decreased by a mean of 76.06 points (95% CI: -89.33 to -62.79) from baseline to the end of the intervention.
• Quality of life improvement was sustained at both 21-month and 33-month follow-up assessments.
• Quality of life was assessed using the ORWELL-97 questionnaire at baseline, at the end of the active program, and at 21 and 33 months post-intervention.
• Long-term follow-up data were available for only a subset of participants.

Participant retention declined over the course of the 9-month program.

• Retention was 88% at the 3-month visit, 67% at the 6-month visit, and 68% completed the 9-month program.
• 308 subjects were enrolled at baseline.
• Long-term follow-up data at 21 and 33 months were available for only a subset of participants.

The program was a multidomain, community-based, non-randomized prospective observational intervention targeting adults with overweight or mild obesity.

• The intervention consisted of regular medical, nutritional, and psychological consultations complemented by compulsory individualized physical training.
• The program lasted 9 months and was conducted in a Hungarian township between 2015 and 2022.
• Participants were adults aged 18-65 years with BMI 25-35 kg/m2 who were motivated to improve their quality of life.
• The primary objective was preventing further weight gain and improving overall health.
• The observational design precludes causal inference.
