Responsive complementary feeding (RCF) vs Other models of complementary feeding (traditional/non-responsive CF)

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Responsive complementary feeding probably reduces the risk of overweight/obesity versus other feeding models (RR 0.41, 95% CI 0.24 to 0.71; moderate certainty).

Responsive complementary feeding (RCF) vs usual care

Z score BMI · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

In one RCT, responsive complementary feeding lowered BMIz at 13 months versus control (0.23 vs 0.42, p=0.01; low certainty).

Non-responsive complementary feeding (NRCF) vs Other models of complementary feeding

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Non-responsive complementary feeding showed no significant association with overweight/obesity across observational studies (very low certainty).

Non-responsive complementary feeding (NRCF) vs Other models of complementary feeding

Weight gain · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Narratively, restrictive NRCF style tended to favor excess weight and coercive/pressuring style tended to favor lower weight (3 of 5 studies each; ungraded).

Baby-led weaning (BLW) vs Traditional complementary feeding (TCF)

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Among observational studies, baby-led weaning was associated with lower odds of overweight/obesity than other feeding models (OR 0.37, 95% CI 0.25 to 0.55), but certainty is very low.

Baby-led weaning (BLW) vs Traditional complementary feeding (TCF)

Infant weight-length gain (achievement of adequate weight) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Baby-led weaning/BLISS did not significantly influence infant weight-length (adequate weight) gain versus other complementary feeding models (pooled OR 1.36, 95% CI 0.18 to 10.51; ungraded).

Responsive complementary feeding (RCF) / other caregivers' feeding practices vs Other models of complementary feeding (traditional/non-responsive CF)

Type 2 diabetes (later in life) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No eligible studies examined the influence of complementary feeding practices on later type 2 diabetes; this is an evidence gap.

Responsive complementary feeding (RCF) vs Other models of complementary feeding (traditional/non-responsive CF)

Physical growth / weight gain · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Two RCTs suggest responsive complementary feeding leads to better weight gain in the first two years, though effects were small and not always sustained (ungraded).

Hypertension (later in life) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No eligible studies examined the influence of complementary feeding practices on later hypertension; this is an evidence gap.

Baby-Led Introduction to SolidS (BLISS) vs Traditional complementary feeding (TCF)

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

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).
