Waist circumference is subject to interoperator variability

and is influenced by:

1) gender;

2) race or ethnicity

Waist circumference explains only 25% to 50% of the

variation in intra-abdominal adipose tissue.

The variability of waist circumference

Fox K et al., Int J Obes Relat Metab Disord, 1993

The study findings suggest a close

relationship among wrist circumference,

its bone component, and insulin resistance

in overweight/obese children and

adolescents, opening new perspectives in

the prediction of cardiovascular disease.

Diabetes Care, Volume 38, supplement 1, January 2015

“Primum non nocere” The challenge for diabetologist is to choose the best safe approach with concerns to potential adverse effects and benefits of intensive glucose control.

afety

ultifactorial

pproach

In diabetic patients relevant cardiovascular risk factors other than hyperglycaemia always coexist. There is a universal agreement that anti-hyperglycaemic therapy should be pursued within a multifactorial risk reduction framework

isk

A careful evaluation of the risk reduction that could really be achieved should always be performed. However the risk of macrovascular complications starts to increase very early, even in the pre-diabetic stages, claiming for precocious management strategies.

herapy

Therapy of diabetes is becoming increasingly complex, due to the complexity of pathophysiology and to the wide therapeutic options. A non univocal, but just a smart approach could be the key to turn therapeutic complexity from a problem into an opportunity.

Maddaloni E .& Pozzilli P. Endocrine, January 2014

The «SMART» diabetologist

Healthcare professionals should aim to encourage and increase patients’

perception about their ability to take informed decisions about disease

management and to improve patient self-esteem and feeling of self-efficacy

to become agents of their own health.

It is important that patients learn to manage and cope with their disease and

gain greater control over actions and decisions affecting their health.

Prevalence of organ-specific autoantibodies

Interaction between obesity, diabetes and

autoimmune thyroid and other diseases is more

than an association of different conditions but a

pathophysiological cluster which requires precise

characterization for the implementation of the

most suitable therapy.
