Investigation of the effect of indoor air pollution prevention protocol on the occurrence of symptoms of sick building syndrome and maintaining balance, sleep quality among older population: a randomized controlled trial

Investigation of the effect of indoor air pollution prevention protocol on the occurrence of symptoms of sick building syndrome and maintaining balance, sleep quality among older population of Shiraz city

Randomized clinical trial using Efron's equal block randomization method, as a blind strain, the sample size was obtained using NCSS-PASS version 15 software, 112 people, which were equally divided into 2 groups (intervention and control).

Training classes and completion of questionnaires are conducted in the Farzangan Shiraz Foundation with the presence of the presenter and clinic manager.Blinding of participants occurs in such a way that they are unaware of the study group allocation and all participants involved in the study assume that all participants have received the intervention.

Inclusion criteria: Age requirements (60-74 years)؛ Residence being an apartment؛ Willingness to participate in the study؛ Living in the current home for at least one month؛ Being at home for at least 8 hours a day؛ Be covered by Farzangan Foundation of Shiraz؛ Answer positively to at least one of the questions in the patient's building syndrome symptoms section؛ Exclusion criteria: Reluctance to continue cooperation؛ older adult death؛ Residence being a villa؛ Moving the older adult to a new place

The elderly were divided into two intervention and control groups, and for the intervention group, classes will be held to teach the indoor air prevention protocol. The control group does not receive training.

Sick building syndrome; Maintaining balance; Sleep quality; Cognitive status.

For sampling, the study samples are randomly divided into different intervention and control groups. In this type of trials, a group of people who are members of Farzangan Foundation of Shiraz and have entry criteria will be selected (random allocation). In each care center for the elderly, there is a list of names of members in the center with a membership code, and each number will be defined with an identification number in the software. 200 members of Shiraz chose to become members of Farzangan Foundation and the patient's building syndrome can be evaluated using the checklist, and 112 people who meet all the conditions for entering the study are selected and randomized using the sampling technique. With Efron's method of equal blocks with the help of PASS software version 15 (2021), the classification is done in a way that classifies these 112 people into 2 equal blocks in each block (56 people) by determining 500 repetitions (repetition of search) between groups and the final sample will be set.

Blinding occurs in participants in such a way that they are unaware of the study group allocation and all participants involved in the study assume that all participants have received the intervention.

The data file will be shared in Mendeley's database in the form of spss software version 25.

The access period starts 3 months after the results are published
