Queensland Perinatal Data Collection (QPDC):
Valid weight range: 35kg - 200kg (035-200).
Collection Methods
Queensland Perinatal Data Collection (QPDC):  
This data will be used in conjunction with self-reported height for Body Mass Index (BMI) and is self reported at conception.

The method of data collection, e.g. face to face interview, telephone interview or self-completion questionnaire, can affect survey estimates and should be reported. 

The data collection form should include a question asking the respondent what their weight is. For example, the ABS National Health Survey 1989-90 included the question 'How much do you weigh without clothes and shoes?'. The data collection form should allow for both metric (to the nearest 1 kg) and imperial (to the nearest 1 lb) units to be recorded. 

If practical, it is preferable to enter the raw data into the data base before conversion of measures in imperial units to metric. However, if this is not possible, weight reported in imperial units can be converted to metric prior to data entry using a conversion factor of 0.454 kg to the lb. 

Rounding to the nearest 1 kg will be required for measures converted to metric prior to data entry, and may be required for data reported in metric units to a greater level of precision than the nearest 1 kg. The following rounding conventions are desirable to reduce systematic over reporting (Armitage and Berry 1994):
nnn.x where x < 5 - round down, e.g. 72.2 kg would be rounded to 72 kg.
nnn.x where x > 5 - round up, e.g. 72.7 kg would be rounded to 73 kg.
nnn.x where x = 5 - round to the nearest even number, e.g. 72.5 kg would be rounded to 72 kg, while 73.5 kg would be rounded to 74 kg.

Queensland Opioid Treatment Program (QOTP) Admission Data Supply Requirement (DSR): Data is collected by completing the Queensland Opioid Treatment Program (QOTP) Admission form. Provide the patient's weight in kilograms.

Perinatal National Best Endeavours Data Set (NBEDS):
It is preferable to collect and record a pregnant female's weight as a measured weight. Where a measured weight has not been provided or it is not possible to ascertain whether the weight has been measured or self-reported, the value 999.9 should be recorded against the Person-weight (measured), total kilograms data element. Data should then be recorded against this conditional self-reported weight data element.
Weight rounded to the nearest whole kilogram is acceptable.
Weight should be recorded in the first trimester, preferably as a measured weight. However, the female's self-reported weight around the time of conception is acceptable if a measured weight is not available.
Comment
Weight is an overall measure of body size that does not distinguish between fat and muscle. Weight is an indicator of nutrition status and health status. Low pre-pregnancy weight is an indicator of poorer gestational outcome in women (Kramer 1988). Low weight is also associated with osteoporosis. In general, change in weight is of interest in adults because it is an indicator of changing health status. Self reported or parentally reported weight for children and adolescents should be used cautiously if at all. It enables the calculation of body mass index which requires the measurement of height and weight (body mass) for adults.
