Study population: he study population consists of a large cohort of 17,466 older women enrolled in the Women's Health Study (WHS), a long-term observational study. These women were initially recruited between 1992 and 1995 for a randomized clinical trial of aspirin and vitamin E for the primary prevention of cardiovascular disease and cancer. The current analysis focuses on a subset of participants who, between 2011 and 2015, wore a tri-axial accelerometer during waking hours for one week to capture measures of daily life gait (DLG) and daily life physical activity (DLPA).

Who may be able to join

  • after menopause or without intention of pregnancy

Who cannot join

  • history of CHD, cerebrovascular disease, cancer (except non-melanoma skin cancer), or other serious illness;
  • history of serious side effects to study treatments;
  • taking aspirin, drugs containing aspirin, or non-steroidal anti-inflammatory drugs \> once a week, or ready to give up the use of these drugs;
  • taking anticoagulants or corticosteroids;
  • Taking vitamin A, E or ß-carotene supplements \> once a week.

About this study

Official title: Data Analysis to Evaluate Which Specific Gait Measures Are Associated with Risk of Injurious Falls

The goal of this study is to understand if specific gait and activity measures can help predict injurious falls in older women. The main questions it aims to answer are:

Can combining daily gait (DLG) and daily physical activity (DLPA) measures more accurately predict the risk of injurious falls? How effective is wearable technology and machine learning in analyzing these activity measures for fall prediction? Researchers will analyze data from the Women's Health Study (WHS), using wearable technology to track daily walking patterns and physical activity, and apply machine learning to assess the likelihood of harmful falls.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Daily Activity Patterns Using Wearable Tri-Axial SensorsDevice

    This intervention uniquely focuses on the prediction of injurious falls by combining daily life gait (DLG) measures (e.g., gait speed, cadence, variability) with daily life physical activity (DLPA) measures (e.g., activity levels, activity fragmentation). Unlike other studies, this analysis leverages data from a large cohort of older women (n=17,466) enrolled in the Women's Health Study (WHS), where participants wore a tri-axial accelerometer for 1 week. Additionally, the study links accelerometer data to long-term health outcomes, specifically fall-related injuries from Centers for Medicare \& Medicaid Services (CMS) records. This is the first study to explore whether combining DLG and DLPA measures, derived from wearable technology, can predict fall-related injuries in an aging population, applying advanced machine learning techniques to this large, anonymized dataset.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Association of Gait Speed with Risk of Injurious Falls (AIM1)

    The study will evaluate the association between gait speed (measured in meters per second) and the risk of injurious falls within one year following the accelerometer assessment.

    Measured: njurious falls within 1 year after baseline assessment using time-to-event analyses.

  2. Association of Cadence with Risk of Injurious Falls (AIM1)

    The study will assess the association between cadence (measured in steps per minute) and the risk of injurious falls within one year following the accelerometer assessment.

    Measured: Injurious falls within 1 year after baseline assessment using time-to-event analyses.

  3. Association of Gait Variability with Risk of Injurious Falls (AIM1)

    The study will assess the association between gait variability (measured as the standard deviation of step times) and the risk of injurious falls within one year following the accelerometer assessment.

    Measured: Time Frame: Injurious falls within 1 year after baseline assessment using time-to-event analyses.

  4. Association of Overall Activity Levels with Risk of Injurious Falls (AIM2)

    The study will evaluate the association between overall activity levels (measured in average accelerometer counts per minute) and the risk of injurious falls within one year following the baseline assessment.

    Measured: Injurious falls within 1 year after baseline assessment using time-to-event analyses

  5. Association of Activity Fragmentation with Risk of Injurious Falls (AIM2)

    The study will assess the association between activity fragmentation (measured by the fragmentation index) and the risk of injurious falls within one year following the baseline assessment.

    Measured: Injurious falls within 1 year after baseline assessment using time-to-event analyses.

  6. Combined DLG and DLPA Measure for Predicting Risk of Injurious Falls (AIM3)

    his outcome will evaluate a single combined score derived from both daily life gait (DLG) and daily life physical activity (DLPA) measures to assess the association with the risk of injurious falls. The combined score will be created incorporating DLG measures (e.g., gait speed, variability) and DLPA measures (e.g., overall activity levels, fragmentation) into a unified predictor.

    Measured: Time Frame: Injurious falls within 1 year after baseline assessment, using combined predictive models.

Secondary outcomes (8)
  1. Association of Self-Reported Exercise History with Gait Speed

    This outcome will assess whether participants' self-reported exercise history is associated with gait speed (measured in meters per second) derived from accelerometer data.

    Measured: Assessed at baseline (self-reported exercise history) and at the time of accelerometer data collection, with data analyzed within 1 year of the baseline assessment.

  2. Association of Self-Reported Exercise History with Gait Variability

    This outcome will evaluate whether participants' self-reported exercise history is associated with gait variability (measured as the standard deviation of step times) derived from accelerometer data.

  3. Association of Self-Reported Exercise History with Overall Activity Levels

    This outcome will assess whether participants' self-reported exercise history is associated with overall activity levels (measured in accelerometer counts per minute) derived from accelerometer data.

  5. Association of Gait Speed with Risk of Injurious Falls (Over 5 Years)

    This outcome will assess whether gait speed (measured in meters per second) is associated with the risk of injurious falls over a 5-year follow-up period.

    Measured: 5 years after baseline.

  6. Association of Gait Variability with Risk of Injurious Falls (Over 5 Years)

    This outcome will assess whether gait variability (measured as the standard deviation of step times) is associated with the risk of injurious falls over a 5-year follow-up period.
