Study summary

Osteoporosis is a multifactorial disease in which genetic predispositions play a key role in its development. A better understanding of family history and clinical manifestations among first- and second-degree relatives can help improve early detection and personalized care for at-risk patients. To this end, we will test a self-administered questionnaire previously developed by our research team. This questionnaire includes the main manifestations associated with rare genetic bone diseases such as osteogenesis imperfecta, hypophosphatasia, and osteopetrosis.

Read the detailed description

The main objective of this project is to test the validity of this new self-administered questionnaire, by studying the concordance between its answers and those obtained from a patient's family tree by telephone.

Primary Objective: To test the validity of a self-administered questionnaire to facilitate the identification of rare genetic bone diseases in adults with osteoporosis.

Secondary Objectives: To adapt the self-administered questionnaire to increase the accuracy of responses compared to those obtained using a family tree, with the aim of using it for clinical screening of rare genetic bone diseases in adults.

Data collection:

Sociodemographic data (age, sex, ethnicity, body mass index, menopausal status, smoking, alcohol consumption, physical activity, history of falls in the past year) and clinical data will be collected from participants' electronic medical records at the CHU de Québec-Université Laval (age at osteoporosis diagnosis, history of osteoporotic fractures, osteoporosis risk category based on the most recent bone density scan, calcium and/or vitamin D supplement use, history of anti-osteoporosis medications, presence of comorbidities, use of prednisone or antihormonal medications) to describe the participants and the severity of their osteoporosis. Other data collection will be conducted in two stages. First, recruited patients will be randomized to either begin with the self-administered questionnaire or the family tree. Then, 3 months later, the people who started with the questionnaire will be able to do the interview for the family tree and vice versa.

Randomization: For this collection, a balanced block randomization will be used to randomly assign patients to one of the two assessment administration sequences. This approach, which corresponds to a crossover design with sequence randomization, will balance order effects and ensure a similar distribution in each sequence. In addition, the use of blocks (of size 4) will ensure that the balance between the two conditions is maintained throughout the recruitment period.

Statistical analyzes:

Descriptive statistics will first be performed to characterize the participants (age, sex, number of first- and second-degree relatives, as well as the clinical manifestations detailed in the self-administered questionnaire) and to report, based on the relationship, the frequency of different clinical manifestations in relatives. In this study, the pedigree will serve as the gold standard to describe the presence or absence of familial bone disease, specifying the degree of affected kinship, the type of inheritance, and the most likely diagnosis (e.g., hypophosphatesia, osteogenesis imperfecta, etc.). The concordance between the responses provided by the self-administered questionnaire and the information from the pedigree will be primarily assessed by calculating the kappa coefficient. This analysis will constitute the primary statistical approach of the study. In addition, secondary analyses will be conducted to determine the sensitivity and specificity of the self-administered questionnaire compared to the gold standard. These measurements will make it possible to evaluate the diagnostic performance of the tool developed in the detection of familial bone disease.

Sample size calculation: The agreement between the two assessment tools will be based mainly on questions with three response categories (Yes, No, Don't know) with respective frequencies assumed to be (0.1, 0.3 and 0.6). The objective being to test whether the agreement, measured by the kappa coefficient, exceeds the threshold of 0.7 (H0: Kappa ≤ 0.7 versus H1: Kappa > 0.7), the comparison will be carried out using a one-sided Z-test for kappa, setting the type I error rate (α) at 0.05. To detect a kappa coefficient of 0.9 with a power of 80%, it is necessary to recruit 58 patients. The sample size was calculated using PASS 2024 software, version 24.0.2.

Interventions

  • OtherSelf-administered questionnaire

    The self-administered questionnaire was previously prepared by the research team for another project. It includes 14 questions addressing the dentition, fractures, joint hypermobility, height, and eye abnormalities present in the participants or their relatives. This questionnaire covers the clinical manifestations of rare bone diseases such as osteogenesis imperfecta, pycnodysostosis, hypophosphatasia, and osteopetrosis. This self-administered questionnaire will be filled online by participant. Average completion time of 20 minutes.

  • OtherFamily tree

    For the family tree, this step is done by a telephone interview lasting a maximum of 45 minutes, depending on the size of the participant's family. The researcher will be able to reconstruct the family history with the index case. The family tree will then contain the family history up to the second degree of kinship with respect to the index cases. The information collected through the index cases when creating the family tree must include, for each relative, biological sex, as well as information on the presence or absence of a rare or genetic bone disease and clinical signs associated with these diseases, such as short stature, bone deformities, deafness, eye problems, etc.

What researchers measure

Primary outcomes

  1. Concordance between the results of the self-questionnaire compared to those obtained by a family tree.

    Descriptive statistics will first be performed to characterize the participants (age, sex, number of first- and second-degree relatives, as well as the clinical manifestations detailed in the self-administered questionnaire) and to report, based on the relationship, the frequency of different clinical manifestations in relatives. In this study, the pedigree will serve as the gold standard for describing the presence or absence of familial bone disease, specifying the degree of affected kinship, the type of inheritance, and the most likely diagnosis (e.g., hypophosphatasia, osteogenesis imperfecta, etc.). The concordance between the responses provided by the self-administered questionnaire and the information from the pedigree will be primarily assessed by calculating the kappa coefficient. This analysis will constitute the main statistical approach of the study.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2026 (actual). Primary completion is estimated for Jul 2027, 15 months after the start.

Of 115 non-industry observational studies under Osteoporosis, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 113. This study's planned 15 months is below that.

Counting every sponsor, half of 126 studies reached it within 51 months; a quarter within 24 and three quarters within 97.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
