- Lung disease requiring oxygen
- Type 1 diabetes or MODY diabetes
Other
- Pregnancy (self-reported)
- Expected overnight travel outside their residence during the study
- HEPA filter within the ACs of the residence (self-reported) or individual use of HEPA filter filter
- Unable to comprehend/sign an informed consent
- Screening visit: BP ≥160/100 mm Hg
- Left upper arm circumference \>17 inches as this will make BP levels inaccurate with the home monitor used
Who the study is looking for
- Age ≥18 and less than 65 years old
- Living in a single residence (home, apartment) located anywhere in Qatar
- Mild systolic hypertension: screening visit systolic BP 130 to 159 mm Hg (off treatment or taking ≤ 2 BP medications that have been stable without changes during prior one week)
- Either:
- Type 2 diabetes patients (HbA1c \> 6.5%) OR Non-type 2 diabetes patients with two or more additional criteria for the metabolic syndrome,
- Waist circumference ≥102 cm if male and ≥88 cm if female
- Fasting triglycerides ≥150 mg/dL (or taking a triglyceride-lowering medication)
- HDL-C ≤ 40 mg/dL if male and ≤ 50 mg/dL if female (or taking an HDL-raising medication),
- Fasting glucose ≥100 mg/dL (or taking an antidiabetic medication)
Age in the registry: 18 years to 65 years · Sex: All · Does not accept healthy volunteers
