Study summary

The LIFE-HOUSE research project is designed to evaluate the impact of a personalized lifestyle intervention program on functional capacity as an approach to quantitating health, and its relationship to well understood disease risk determinants.

LIFE-HOUSE will utilize an innovative Tent-Umbrella-Bucket design.

Participants will gather under the Tent of an all-inclusive 'N of 1' Case Series providing a shelter of Functional Medicine interventions against the storm of chronic disease. Under this Tent are a collection of Umbrellas where participants with similar clinical challenges are evaluated as clinically defined groups with loose guidelines for the planned interventions. Finally, participants standing under these Umbrellas may step into specific Buckets that gather individuals with nearly identical clinical presentations into more formally described prescriptive randomized arms for intervention.

Read the detailed description

It has been suggested that the best medicine should value four principles (4P) - medicine should be personalized, predictive, preventative and participatory. This 4P Medicine will thus be personalized and patient centered with a focus on the person who has the disease and not the disease the person has. It will be predictive as it identifies the pre-clinical trend/decline towards illness sooner than onset of symptoms that herald the loss of function and health. It will be preventative as the information gathered should offer opportunities to modify these trajectories towards illness and finally it will be participatory as individuals will be intimately involved in the gathering of data to identify trends and in the application of lifestyle measures to improve their lives.

There is a significant unmet need to identify the value of a personalized lifestyle intervention program for improving functional health outcomes. Whereas disease is well understood from traditional pathology-based indices, health is less easily defined. Historically, healthy has been the default term that is applied to an individual who is not recognized as having a disease. This definition of health as the absence of disease has resulted in the delivery of health and wellness as often lying outside the purview of medicine.

An evolving definition of health, however, is to recognize that it is related to the functional capacity of the individual. Functional capacity can be categorized in four assessment areas: physiological, physical, cognitive and emotional. All four of these subcategories are quantifiable by both qualitative and quantitative metrics. The effects on health of a multi-modal personalized lifestyle medicine intervention program can best be evaluated by using functional determinants.

Functional Medicine is an integrative medicine philosophy that uniquely incorporates 4P Medicine with a focus on function and dysfunction and the necessity to consider the physiological events that determine the balance between the two. The LIFE-HOUSE research project is designed to evaluate the impact of a personalized lifestyle intervention program on functional capacity as an approach to quantitating health, and its relationship to well understood disease risk determinants.

Individuals will be offered the opportunity to participate in all Umbrellas and Buckets for which they qualify. They may accept or reject participation in any Umbrella or Bucket and yet remain eligible for participation in the overall Tent. Due to the structure of the uniquely defined yet overlapping system of Umbrellas and Buckets, a specific Subject may participate consecutively and/or sequentially in a series of Umbrella and Buckets as applicable and their data may be included in multiple Umbrella and Bucket analyses.

What researchers measure

Primary outcomes

Medical Outcomes Study Short Form 36 (MOS SF-36) questionnaire
The MOS SF-36 is an indicator of overall health status. It has an eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0 - 100 Lower scores = more disability, higher scores = less disability.
Time frame: Change from baseline at 12 months
University of Rhode Island Change Assessment (URICA) questionnaire
URICA questionnaire is a 32 item self-report measure that includes 4 subscales measuring the stages of change: Precontemplation, Contemplation, Action, and Maintenance (there is also a 24 item version). Responses are given on a 5 point Likert scale ranging from (1=strong disagreement to 5=strong agreement),
Time frame: Change from baseline at 12 months
Depression Anxiety, Stress Scale (DASS) questionnaire
The Depression, Anxiety and Stress Scale is a 21 items questionnaire that includes a set of three self-report scales designed to measure the emotional states of depression, anxiety and stress. Outcome is divided into normal, mild, moderate, severe, and very severe for each of the 3 categories: Depression, Anxiety, and Stress. A low score represents the normal and the higher the score the more severe the outcome.
Time frame: Change from baseline at 12 months

Beck Depression Inventory (BDI)
BDI is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. Rating system: 1-10: These ups and downs are considered normal; 11-16: Mild mood disturbance; 17-20: Borderline clinical depression; 21-30: Severe depression; over 40: Extreme depression
Time frame: Change from baseline at 12 months
Beck Anxiety Inventory (BAI)
BAI is a multiple-choice self-report inventory that is used for measuring the severity of anxiety in children and adults.The BAI contains 21 questions, each answer being scored on a scale value of 0 (not at all) to 3 (severely). Higher total scores indicate more severe anxiety symptoms. The standardized cutoffs\[4\] are: 0-7: minimal anxiety 8-15: mild anxiety 16-25: moderate anxiety 26-63: severe anxiety
Time frame: Change from baseline at12 months
Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Test
PROMIS Sleep Disturbance Test is a self-scored test to identify sleep disturbance. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance. The T-scores are interpreted as follows: Less than 55 = None to slight 55.0-59.9 = Mild 60.0-69.9 = Moderate 70 and over = Severe
Time frame: Change from baseline at 12 months
Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety Test
PROMIS Anxiety test is a 7-item questionnaire that assesses the pure domain of anxiety in individuals age 18 and older. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 7 to 35 with higher scores indicating greater severity of anxiety. The T-scores are interpreted as follows: Less than 55 = None to slight 55.0-59.9 = Mild 60.0-69.9 = Moderate 70 and over = Severe
Time frame: Change from baseline at12 months
Patient-Reported Outcomes Measurement Information System (PROMIS) Depression Short Form (SF)
PROMIS Depression SF is an 8-item questionnaire that assesses the pure domain of depression in individuals age 18 and older. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of depression.The T-scores are interpreted as follows: Less than 55 = None to slight 55.0-59.9 = Mild 60.0-69.9 = Moderate 70 and over = Severe
Time frame: Change from baseline at 12 months
