Overview

Retrospective cohort study reveals early visit frequency boosts weight loss in adults with overweight or obesity, indicating that front-loading dietetic care improves clinical outcomes.

Key Points

  • To assess the timing, achievement, and maintenance of clinically relevant (≥5%) weight loss over 12 months of routine primary care dietetic treatment and determine its association with treatment intensity.
  • Retrospective cohort study using electronic health record (EHR) data from over 70 primary care dietetic practices in the Netherlands between 2016 and 2020.
  • Included N = 4,503 adults (age ≥ 18 years, BMI ≥ 25 kg/m²) receiving dietetic treatment with a 12-month follow-up.
  • Evaluated weight loss at 3, 6, 9, and 12 months using multivariable logistic regression adjusted for visit frequency, visit time, sex, age, BMI, and comorbidity.
  • Overall, 33% of patients achieved ≥5% weight loss from baseline, with 60% of successful patients reaching this milestone within the first 3 months.
  • Each additional dietetic visit in the first 3 months was associated with a threefold increase in the odds of achieving ≥5% weight loss (OR = 3.0).
  • Each additional visit between months 3 and 6 was associated with 61% higher odds of treatment success.
