Introduction. Existing evidence indicates that the best treatment model for obesity leading to successful weight loss consists of a so-called comprehensive lifestyle intervention program; but the offer, implementation, and coverage of this kind of programs for the diagnosis, management, and follow-up of people living with obesity are limited. So, the aim of this study was an evaluation of the feasibility and effectiveness of a comprehensive care program for obesity in a public tertiary hospital in Mexico. Methods. An observational, longitudinal, and retrospective study evaluated a six-month long medium intensity comprehensive care program (seven visits focused on medical, nutritional, psychological, and psychiatric diagnosis and treatment). A total of 1017 people living with obesity were recruited for the program. Logistic regression models were used to predict the factors associated with attendance and weight loss. Results. Of the 1017 participants, 661 completed the program (65% retention rate) and attended 4.9 ± 1.9 visits each, with 40.1% losing ≥5% of their starting weight (X = 4.3 ± 4.4%). From Visit 1 to Visit 7 the participants that completed the program had weight decreases of Δ = −4.8 kg, and BMI −2.3 kg/m2; p < .01. Each additional visit increased the likelihood of a 5% weight loss [OR 1.90, 95% CI, 1.51 to 2.38, p < .001] and 10% [OR 2.45, 95% CI, 1.49 to 4.02, p <.001], becoming statistically significant after attending more than four visits. Each additional year of age increased the likelihood of losing ≥5% body weight [OR 1.01, 95% CI, 1.00 to 1.03, p <.05] and increased the likelihood of completing the program [OR 1.02, 95% CI, 1.00 to 1.03, p <.01] after controlling for sex, weight, BMI, and psychiatric and weight loss medications. Discussion/Conclusion. This study demonstrates the feasibility and effectiveness of a six-month comprehensive program for obesity in a public hospital in Mexico.
