Condition or disease | Intervention/treatment | Phase |
---|---|---|
Aging | Dietary Supplement: dietary nucleotides Dietary Supplement: placebo | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 122 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | completely randomized design |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | The experiment designers used seed number 1234 to generate a random sequence of 120 random numbers on SAS software and divided the 120 random numbers into two groups based on the size of the random numbers. The larger number is Group A, and the smaller number is Group B. Both intervention drugs and placebos are produced by pharmaceutical companies without any labels and look exactly the same. Neither the trial designer nor the pharmacist participated in the trial. The researchers were responsible for recruiting subjects and assigning serial numbers according to inclusion criteria. Caregivers are responsible for dispensing, reviewing, and documenting medications. Investigators are responsible for measuring and filling out questionnaire items. Medical examinations and sample collection are carried out by hospital professionals. |

- Pittsburgh sleep quality index (PSQI) [ Time Frame: Baseline ]Items are categorized into seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, sleep medication, and daytime dysfunction. The possible score range for each component is 0 (no difficulty) to 3 (severe difficulty). The seven component scores are summed to produce a global score; higher scores represent poorer subjective sleep quality.

- Scores of Quality of life [ Time Frame: Baseline ]Quality of life was measured 36-Item Short Form Survey (SF-12) questionnaire. The items are grouped into eight domain scores: physical functioning, role limitations due to physical health, pain, general health, energy, social functioning, role limitations due to emotional problems and emotional well-being. Domain scores can be collapsed to a physical component summary Physical health (PCS) and a mental component summary Mental health (MHS). Each score ranges from 0 to 100, with higher values representing the better self-perceived health-related quality of life.
