Study of Human Adipose Tissue (LOSHAT) (LOSHAT)
Longitudinal Observational Study of Human Adipose Tissue (LOSHAT)
調査の概要
詳細な説明
The investigators will ask all subjects that have previously been examined at the investigators laboratory (from 1992 and forward) in studies of adipose tissue function if they are interested to participate in a new study.
Previously obtained results from examinations of adipose tissue, anthropometric measurements and blood samples will be used as baseline. In addition, saved blood samples and samples from old fat biopsies can be re-investigated in some cases.
The new investigation includes a questionnaire that the subjects can answer by mail or email. In addition, anthropometric measurements and blood pressure determination will be performed at a primary health care center and blood samples will be collected for analysis of fasting glucose, HbA1C and lipids.
Information regarding all previously investigated subjects will also be collected from several Swedish national patient registries such as the Patient Register, Prescribed Drug register and Cause-of Death register.

メジャーの説明 |
時間枠 |
|---|---|---|
|
Body mass index
時間枠:2018 to 2022
|
Body weight (in kilogram) will be assessed with a regular scale.
Height will be measured with a tape measure (in centimeters).
Body mass index (BMI) will be calculated with the formula weight (kg) divided by height^2 (in meter).
Changes in BMI from baseline values will be analysed.

2018 to 2022
|
|
Fasting glucose
時間枠:2018 to 2022
|
Fasting plasma glucose will be assessed and divided into normal glucose (glucose < 6.1 mmol/L), impaired fasting glucose (glucose 6.1-6.9 mmol/L) or type 2 diabetes (glucose > 6.9 mmol/L).

2018 to 2022

Number of participants with metabolic syndrome
時間枠:2018 to 2022
|
Metabolic syndrome is defined according to International Diabetes Federation, Waist circumference ≥102 cm for men or ≥88 cm for women.
In addition to this 2 of the following; Raised triglycerides: > 150 mg/dL (1.7 mmol/L), or specific treatment for this lipid abnormality; Reduced HDL cholesterol: < 40 mg/dL (1.03 mmol/L) in males, < 50 mg/dL (1.29 mmol/L) in females, or specific treatment for this lipid abnormality; Raised blood pressure (BP): systolic BP > 130 or diastolic BP >85 mm Hg, or treatment of previously diagnosed hypertension; Raised fasting plasma glucose (FPG): >100 mg/dL (5.6 mmol/L), or previously diagnosed type 2 diabetes.
Scores are 0-5.
≥ 3 is defined as metabolic syndrome.
