Encouraging direction, but not yet definitive.
In a retrospective cohort of 289 school-aged obese children, a 12-month family-centered comprehensive lifestyle intervention was associated with greater improvements in BMI, waist circumference, body fat percentage, systolic blood pressure, insulin resistance, inflammatory markers, and quality of life compared to routine guidance alone. The authors explicitly caution that the retrospective, non-randomized design limits inference to hypothesis-generating associations rather than causal effects.
Retrospective, non-randomized cohort comparison. School-aged children aged 6–12 years diagnosed with obesity at Qingdao Chengyang District People's Hospital, China, enrolled from March 2021 to March 2024.. Intervention: 12-month family-centered comprehensive lifestyle intervention (multidisciplinary program); specific components not detailed in the provided abstract.. Compared with: Routine guidance (standard health education). n = 289. Qingdao Chengyang District People's Hospital, China (single centre).
BMI reduction favoring intervention: adjusted mean difference -1.23 (95% CI -1.80 to -0.66, p<0.001) Waist circumference reduction: adjusted mean difference -4.13 cm (95% CI -5.68 to -2.58, p<0.001) Body fat percentage reduction: adjusted mean difference -2.61% (95% CI -3.60 to -1.62, p<0.001)

The findings suggest family-centered lifestyle interventions may yield measurable cardiometabolic benefit in obese children over 12 months. However, clinicians should weigh these results cautiously given the retrospective non-randomized design; a randomized controlled trial would be needed to establish causality and guide practice changes.
A retrospective cohort study showing consistent improvements across multiple cardiometabolic endpoints in obese children after 12 months of family-centered intervention, but limited by non-randomized design and potential confounding despite adjusted analysis.

Childhood obesity increases risks for metabolic and cardiovascular disease, yet long-term effectiveness of family-centered interventions remains unclear. This retrospective study evaluated associations between a family-centered comprehensive lifestyle intervention and changes in body composition and cardiometabolic indicators in school-aged children with obesity. Children aged 6–12 years diagnosed with obesity at Qingdao Chengyang District People’s Hospital from March 2021 to March 2024 were included. A total of 289 participants were categorized into the Family-Centered Intervention Group ( n = 162) receiving a 12-month multidisciplinary program or the Routine Guidance Group ( n = 127) receiving standard health education. Anthropometric measurements, body composition, blood pressure (BP), lipid profiles, glucose metabolism indices, inflammatory markers, liver function, uric acid, cardiovascular structure, and health-related quality of life were assessed at baseline and at the 12-month follow-up. At the 12-month mark, the intervention group demonstrated markedly greater associations with enhancements in body mass index (BMI, adjusted mean difference: -1.23, 95% CI: -1.80 to -0.66, adjusted p < 0.001), waist circumference (adjusted mean difference: -4.13, 95% CI: -5.68 to -2.58, adjusted p < 0.001), body fat percentage (adjusted mean difference: -2.61, 95% CI: -3.60 to -1.62, adjusted p < 0.001), systolic BP (adjusted mean difference: -4.23, 95% CI: -6.12 to -2.34, adjusted p < 0.001), homeostasis model assessment of insulin resistance (HOMA-IR, adjusted mean difference: -0.46, 95% CI: -0.77 to -0.15, adjusted p = 0.004), high-sensitivity C-reactive protein (hs-CRP, adjusted mean difference: -0.57, 95% CI: -0.82 to -0.32, adjusted p < 0.001), and total Pediatric Quality of Life Inventory (PedsQL) score (adjusted mean difference: 4.73, 95% CI: 1.82 to 7.64, adjusted p = 0.002), along with more favorable lipid profiles, lower uric acid, improved cardiac structure, and reduced carotid intima-media thickness (all p < 0.05). In this retrospective cohort of school-aged children affected by obesity, a family-centered comprehensive lifestyle intervention was associated with favorable body composition, cardiometabolic profiles, and overall quality of life related to health over 12 months. Given the retrospective and non-randomized design, these findings should be interpreted as hypothesis-generating associations rather than causal effects.
