Australian National Diabetes Information Audit & Benchmarking (ANDIAB) 2011 Final Report

2.4.6 Lipids

Data on the level of lipids (cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) and whether individuals are 'fasting' or 'on anti-lipid therapy'

Page last updated: December 2011

Recorded

Most recent/current Lipids [Cholesterol (Chol), LDL Cholesterol (LDL), HDL Cholesterol (HDL), Triglycerides (Trigs)], in the last 12 months, ‘Fasting’ [No/Yes], and ‘On Anti-Lipid Therapy’ [No/Yes].

% Missing (Overall)

Cholesterol 23.8% ; LDL Cholesterol 37.7% ; HDL 33.7% ; Triglycerides 24.7% ;
Fasting 36.1% [20.9% conditional on any lipid result having been recorded];
On Anti-Lipid 11.9% [6.4% if conditional on any lipid result recorded].

This meant that in 52.2% & 51.7% of records respectively, a Cholesterol &/or Triglyceride result and Fasting status were available for Fasting Lipid analysis. [This was 46.9% of the records for HDL Cholesterol and 45.2% for LDL Cholesterol provided by sites].

Results

[a] Mean SD :
Table 15[a] gives overall results for Lipids for the Total Group and broken down by ‘Fasting’ status. There were 3526 Cholesterol levels (2416 Fasting), 2946 LDL Cholesterol levels (2090 Fasting), 3067 HDL Cholesterol levels (2172 Fasting) and 3487 Triglyceride levels (2394 Fasting) provided overall. See Frequency Tables for n= and range data.

[b] LDL Cholesterol
Table 15[b] shows calculated LDL Cholesterol levels by arbitrary cut points.

Tables on Pages 107-134 of Appendix 5 show the breakdown of Mean Lipids (Total then Fasting) by Diabetes Type for all data, thence Target Lipids (Total then Fasting).The Graphs show the spread/comparison of site’s results ranked in order for totals and by Diabetes Type. The pages are All Sites Data which in 2011 is all Adult Forms Data.
