The Bundi Children, New GuineaLampl et al., Ann Hum Biol, 1978 • 7-13 year old, stunted children (n = 86, mean height 114 cm, weight 20 kg) • 8 months intervention (random allocation) • Normal diet (roots and potatoes, 5440 kJ, 11 g protein / day) • Added skimmed milk powder (10 g protein / day, 5 days per week) • Added skimmed milk powder (20 g protein / day, 5 days per week)

Other studies • Alabama, 1945 • 82 kids, 1-10 / 4-15 years, 4 / 8 vs 0 dl milk / d • 1.23 cm lenght gain difference in 20 months • Paired allocation, Dreizen et al., Growth, 1950 • Britain • 520 7-8 year olds, ”disadvantaged” • randomised, 1.9 vs 0 dl / d • 0.3 cm lenght gain difference in 21.5 months (130 g weight) • Baker at al., J Epid Comm Health, 1980
Other studies • China • 757 girls, age 10-12 years, 3.3 vs 0 dl milk / d • 0.7 cm lenght gain difference in 24 months • Cluster randomised (6), Du et al., Br J Nutr, 2004 • A number of indeterminate or negative results from the North • In some trials, benefit if initially low HAZ • Many ecological and observational studies document an association between milk intake and height or linear growth • Possibility for confounding
IGF-1 and linear growth • IGF-1 is affected by GH • GH-deficient children do not grow
Cow milk intake and IGF-1 • Intervention studies few, 2 child studies • 12-y girls, 5.5 dl milk / d, 18 months • Minor association to IGF-1 at 18 months, p<0.05 if adjustments, energy confounder • Randomisewd, Cadogan et al., BMJ, 1997 • 24 8-y boys, 1.5 l milk vs same protein in meat, 7 days • Increased concentration of IGF-1 and IGF-1 / s-IGFBP-3 • Hoppe at al., Eur J Clin Nutr, 2004

Additional information • Observational study, 2.5 y kids, Denmark • Direct association between milk intake and serum IGF-1 concentration and lenght • Big effect: 2 6 dl milk intake increase vs 30% increase in IGF-1 • Hoppe at al., Am J Clin Nutr, 2004 • Some negative and positive results both from adults and children (few studies) • Vegans vs vegetarians and meat-eaters
