Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

People with cystic fibrosis (CF) now frequently live into adulthood and with this extended life expectancy has come new clinical problems. Poor bone health, including osteoporosis and bone fractures, is one of these increasingly important conditions. Preventing the negative outcomes of poor bone health in later life is primarily related to ensuring optimal growth (weight and height) and obtaining maximal amount of bone mass during growth and development. This study will identify factors that influence bone health in a sample of children, adolescents and young adults as measured by dual energy x-ray absorptiometry and new bone densitometry methods (peripheral quantitative computerized tomography \[p-QCT\] and bone sonometer). We will also identify factors which influence changes in bone status over a 12-month follow-up period in a subsample of people with CF.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A total of 100 subjects with CF and pancreatic insufficiency (8-25 y, half female) will be recruited from the Children's Hospital of Philadelphia (CHOP) and the Delaware Valley region. All subjects will have baseline measurements obtained at the Nutrition and Growth Lab at CHOP. A subset of subjects will return for 12-month follow-up measurements.

We will evaluate the influences on bone health, including: gender, stage of pubertal development, body weight and height, food intake (especially calcium and vitamin D), use of steroid medications by mouth, IV administration or inhalation, physical activity and lung health. We will also follow the changes in bone health and growth over 12 months, and see what factors are associated with good and poor bone development.

In addition, the information from this study will be very important to planning the future trials of medication and other interventions to treat and, hopefully, to prevent poor bone health in people with CF.
