Question

I used a multivariable linear regression analysis to complete the following table relating the characteristics listed to BMI as a continuous variable.Then, describe how each characteristic is related to BMI. Can you explain how each characteristic is related to BMI? I'm having a hard time understanding the chart

Outcome Variable: BMI, kg/m²

Characteristic	Regression Coefficient Crude Models	p-value	Regression Coefficient Multivariable Model	p-value
Age, years	0.06	<0.001	-0.02	<0.001
Male sex	0.58	<0.001	-0.99	0.004
Systolic blood pressure, mmHg	0.0603	<0.001	0.0571	<0.001
Total serum cholesterol, mg/dL	0.113	<0.001	0.0064	<0.001
Current smoker	-1.402	<0.001	-1.282	<0.001
Diabetes	2.292	<0.001	1.23	0.001

Answer 1

Sure,

BMI IS YOUR dependent variable and other all independent variable. BMI is depends on all independent variable. Means if change the values of Independent then change the valurs of dependent variable.

but how many change ???

if change the independent valaue then dependent variable (BMI) change multiply by corresponding coefficient value...

like ke for example

diabetes change by one unit then dependent variable changes 2.292 kg/m3

Current smoker impact negative on BMI

MEANS current smoker change the value by one unit then BMI decreases by 1.402 kg/m2

(I thing current smoker is variable 0 or 1)

if value present1 in observation then your bmi decrease by 1.402 ..(-1.402)
