Introduction

The aim of the Northern Territory Government’s Healthy Under 5 Kids program (HU5K) is to improve the growth and developmental status of children 0-5 years of age living in NT remote and urban areas.

The program covers a broader range of measures beyond growth. These will be incorporated into future reports. This report has a historical reference that focuses on growth indicators for children living in remote areas that aim for better than 80% measurements coverage of each community, in each year (see Explanatory Notes - a). This involves routinely collected measurements of weight, height/length and haemoglobin from which were calculated the indicators height for age, weight for age, and weight for height according to the both the World Health Organisation (WHO, 2006) rules (http://www.who.int/

childgrowth/standards/technical_report/en/index.html) and the Center for Disease Control - Atlanta (CDC, 2000) rules (http://www.cdc.gov/growthcharts).

This report presents the results of the Healthy Under 5 Kids program from October to April each year across the NT rural areas including details of the program coverage, the number of children measured compared with the number of resident children, the rates of stunting, wasting, underweight and anaemia.

In this report the anaemia cut-off criterion endorsed by Central Australian Rural Practitioners Association (Central Australian Rural Practitioners Association 2009. CARPA Standard Treatment Manual, 5th edn, Central Australian Rural Practitioners Association, Alice Springs), is presented. The height and weight measurements are interpreted with both WHO 2006 Growth Standard and the USA CDC 2000 Growth Reference.

Explanatory Notes

a Differences in number of measured children are due to different (WHO / CDC) age calculation definitions

b Where coverage is less than 80% this will affect rates measures. Data values in red are to alert the reader to interpret the related rates with caution.

Disclaimer

This report is presented by the NT Department of Health for the purpose of disseminating health information for the benefit of the Departmental clients and potential users of this report.

The Department is not providing warranties as to the information's accuracy, completeness, suitability or fit for purpose.

This report supersedes any previous reports. Over time data corrections and improved data processing and calculation methods are implemented that may result in changed values and trends for earlier years data. These variations are highlighted where appropriate.

When using the data in this report, the main content of the information must not be altered. The editing

of data or any errors in the manipulation of data due to incomplete or uncertain data domain knowledge

may result in distortion or misinterpretation of information.

Version Control

Report Title: Healthy Under 5 Kids Data Collection Program NT Annual Report 2011 Report Version: 1.0.0

Compiled by: Emil Stamatoiu, Health Service Information Branch, DoH Data as per: Wednesday, December 28, 2011

HU5K Metadata

Inclusions

Age Only children aged less than 60 months at the beginning of the reporting period, are included.

Deceased For deceased children all related data is excluded from current and future reporting.

Small number Only communities with 20 or more children are included in this report.

Children's Demographics

Resident Children Combined service population of participating communities only.

NTPOP Estimated Northern Territory Indigenous Resident Population in Age Group 0-4 (inclusive) for participating plus non-participating communities. Source ABS.

WHO Growth Age Age in calculations are for “completed months”, and DoH reports adopt the method used by the

“WHO Anthro” and “WHO AnthroPlus” calculators that is, all fractions are discarded. E.g. 26.9 months is 26 months.

For a child who has received a HU5K check their age in completed months is calculated at the

"date of HU5K check".

For a child who has not received a HU5K check their age in completed months is calculated at the

"HU5K survey start date".

CDC Growth Age Calculated as per WHO Growth Age (except that 0.5 is added to the result).

(e.g. if "date of HU5K check" - "date of birth" is 59.9 months, the child will be 59.5 months, if "date of HU5K check" - "date of birth" is 59.1 months the child will be 59.5 months.)

Resident District Reflects health data for children of district only.

Survey District Reflects measurement activity for children measured in district, no matter where they were measured.

Survey Results for Growth Charts

Survey Period Refers to the HU5K Survey Period starting 15 October and ending 15 April each financial year.

Z Scores This report calculates height-for-age Z-scores (HAZ), weight-for-age Z-scores (WAZ) and weight- for-height Z-scores (WHZ) against the WHO Standard and CDC growth reference tables.

WHO Growth Standard

HU5K Z-scores are represented as references to normal population distribution by Z-scores as calculated against the WHO Child Growth Standard 2006.

http://www.who.int/childgrowth/standards/technical_report/en/index.html.

CDC Growth Reference

HU5K growth status values are represented as references to normal population distribution by Z- scores as calculated against the USA CDC Child Growth Reference.

http://www.cdc.gov/nchs/about/major/nhanes/growthcharts/datafiles.htm.

WHO Stunted Analysis of the child’s height-for-age status. A child is ‘Stunted’ if their WHO HAZ < -2.

WHO Underweight Analysis of the child’s weight-for-age status. A child is "Underweight" if their WHO WAZ < -2.

WHO Wasted Analysis of the child’s weight-for-height status. A child is "Wasted" if their WHO WHZ < -2.

CDC Stunted Analysis of the child’s height-for-age status. A child is "Stunted" if their CDC HAZ < -2.

CDC Underweight Analysis of the child’s weight-for-age status. A child is "Underweight" if their CDC WAZ < -2.

CDC Wasted Analysis of the child’s height-for-age status. A child is "Stunted" if their CDC HAZ < -2.

CARPA 5th Edition guidelines for Anaemia Status

Analysis of the child’s raw Haemoglobin reading (g/L). If the Haemoglobin reading is <105g/L for a child between 6 and 11 (inclusive) months or < 110g/L for a child between 12 and 59 (inclusive) months, then the child is identified as anaemic.

CARPA 4th Edition guidelines for Anaemia Status

Analysis of the child’s raw Haemoglobin reading (g/100mL).

If the Haemoglobin reading is < 11g/100mL for a child between 6 and 59 (inclusive) months then the child is identified as anaemic.

Expected proportion

Based on statistical method it is expected that 3% only would have health issue. (Normal curve Standard Deviation.)

Rounding Errors

Pie Charts Where rounded to integer values the sum of all values might not be 100%.

Tables Where results are percentages the sum of all values in column might not be 100%.
