A study on height and body mass index in Fragile X syndrome suggested that height growth decreases with age and is slightly but significantly lower than the general population by adulthood. Weight and BMI increased with age and were quite a bit higher than the general population by adulthood. Antipsychotic use was associated with higher BMI, while stimulants and anticonvulsants were associated with lower BMI. This suggests that the deficit in physical activity in Fragile X syndrome identified in FORWARD may play a role in high BMI.
