Biometrics Flashcards
1
Q
Define biometrics
A
- The science and technology of measuring and analyzing biological data
2
Q
Biometric screening provides
A
- Baseline data to guide corporate wellness programming
3
Q
Conventionally a wellness screen includes
A
- Heart rate
- Blood pressure
- Body composition
- Aerobic capacity
- Basic blood work, balance, ROM, strength
4
Q
Describe continuous heart rate
A
- Higher temporal resolution required
- Preferably based on electrical signal
- Continuous plethysmography
- Continuous photoplethysmography
5
Q
Difference between a wrist cuff and continuous BP
A
- Wrist cuff: more streamlined & the good ones are sufficiently reliable
- Continuous: not a clinical priority right now especially if already have ECG
6
Q
Methods for body composition
A
- Direct measurement: cadavers ONLY
- Air or underwater densitometry
- DXA Scanning
- Skinfold calipers
- Circumference measurements
- Bioelectrical impedance
7
Q
Ways to measure aerobic capacity
A
- Direct: maximal oxygen consumption (VO2 Max)
- Indirect: equations used to predict VO2 Max from submaximal tests
8
Q
Screenable drivers of population health
A
- HTN
- CBC and glucose
- Body composition
- Behavior: substance use, risk taking
9
Q
Variables to screening theory
A
- Cost of the screen
- Sensitivity/specificity of the screen
- Cost of the pathology (untreated)
- Cost of the intervention
- Expected benefit of the intervention
- Expected risks associated with intervention
10
Q
What are the 4 possible outcomes to screening test
A
- True postiive
- True negative
- False positive
- False negative
11
Q
Do screening tests work
A
- Yes on 2 levels
- Increasing awareness
- Enabling preventive behavioral change
12
Q
What is mHealth
A
- Sensors abound
- Data storage is cheap
- Information is king
