Growth in people with Down syndrome differs from the general population. Mean birthweight at term (3KG) is less than in typical babies, and weight gain is slower.The difference in growth rates continues throughout childhood so that short stature is characteristic with mean adult height 146cm for women and 157 cm for men. Whilst this may in part be constitutional, associated medical conditions, and feeding difficulties also contribute. Down syndrome specific growth charts should be used to identify those children whose growth deviates from that expected for a child with Down syndrome, who should be investigated for underlying pathology.
Obesity also commonly occurs in Down syndrome , but is not inevitable.The Down syndrome specific charts do suggest that overweight is the norm so Standard BMI charts , or the BMI look up chart on the UK Down syndrome specific charts should be used to identify those who may be overweight. Assessment for possible medical causes and management, including advice re diet and excercise should be as for the general population.
