Brief Summary
This study is conducted in the United States of America (USA). The aim of this observational study is to collect data concerning the treatment outcomes and safety for children and adults who are prescribed Norditropin®. Specific objectives include: 1) developing models defining the relationship of Norditropin dose to changes in insulin-like growth factor (IGF-I) and treatment outcomes, accounting for independent factors such as age, gender and puberty and 2) determining the relative predictive values of peak growth hormone (GH) and IGF-I levels and other factors before treatment to clinical outcomes.

Outcome Measures
Primary Outcomes (2)
Change in height, measured as the height standard deviation score (HSDS), from the measurement made by the physician at study entry to the most recent clinic observation, end of GH treatment, de-registration, or change of clinic.
measurement made by physician at study entry, annually, or more frequently at physician discretion during the study.
Change in waist/hip circumference ratio for adult patients
measurement made by physician at study entry, annually, or more frequently at physician discretion during the study
Secondary Outcomes (5)

Eligibility Criteria
Patients from both general and specialty practice settings, existing and new users of growth hormones, who have been deemed appropriate to receive Norditropin® as part of routine out-patient care by the prescribing physician.
You may qualify if:
- Informed consent obtained
- Children or adult patients treated with Norditropin® for an appropriate condition as prescribed by their physician
You may not qualify if:
- Patients not being treated with Norditropin®
- Patients who have discontinued treatment with Norditropin®
