Efficacy of an intervention in the nutritional status and consumption of ultra-processed foods in children with obesity treated in primary health care in Brazil.
Article in BMC nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05966259 (Management of Childhood Obesity in the Context of Primary Health Care), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
introductionEffectivechildhood obesity management requires multicomponent interventions in Primary Health Care (PHC), engaging families, communities, and healthcare professionals to foster healthier behaviors.
objectiveThis study evaluated the effect of a controlled intervention on the nutritional status and ultra-processed food (UPF) consumption of children with obesity receiving PHC services.
methodsA randomized clinical trial was conducted with children from PHC units in Betim, Minas Gerais, Brazil. Twenty units were randomly selected and allocated into control (CG) and intervention groups (IG). Children aged 6–10 years with obesity (z-score ≥ +2 for BMI/age) were included. The estimated sample size was 47 per group, considering 20% loss. The IG received monthly activities with four weekly sessions (≥26 contact hours) and five consultations. The CG followed a similar protocol with up to 9 contact hours. Sociodemographic, nutritional, and UPF consumption data were collected through a questionnaire covering 11 food groups. Intention-to-treat analysis compared mean UPF consumption, BMI/age z-score, and BMI (kg/m²) within and between groups post-intervention for a period of 9 months.
resultsA total of 727 eligible children were identified and 167 were randomized, with 79 assigned to the control group and 88 to the intervention group. Of these, 45 children in the control group and 49 in the intervention group. The intervention significantly reduced UPF consumption in IG at visit 3 [95% CI: -0.95 (-1.87; -0.04)], visit 4 [95% CI: -1.35 (-2.215; -0.49)], and visit 5 [95% CI: -0.94 (-1.83;-0.05)]. No significant differences were found for BMI or BMI/age z-score (p>0.05).
conclusionThe intervention effectively reduced UPF consumption. Although no BMI/age reduction was observed, it contributed to weight maintenance and should be considered in PHC childhood obesity strategies.
