Baby-Led Introduction to SolidS (BLISS) vs Traditional complementary feeding (TCF): Overweight/obesity risk
- Population
- Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries
- Intervention
- Baby-Led Introduction to SolidS (BLISS)
- Comparison
- Traditional complementary feeding (TCF)
- Outcome
- Overweight/obesity risk
In RCTs, BLISS did not significantly change overweight/obesity risk versus traditional feeding (RR 0.15, 95% CI 0.00 to 17.79; low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
