Summary measure for all GPs was given using a frequency weighed mean value with a 95% CI.
Frequency of weighing oneself was divided into a group with a low frequency of weighing oneself (0 'every two weeks or less', N = 671 [51.7%]) and a group with a high frequency of weighing oneself (1 'weekly or more often', N = 627 [48.3%]).
Calibration frequency of weighing machine should be at least twice per month.
Observational evidence from behavioral weight control trials and community studies suggests that greater frequency of weighing oneself, or tracking weight, is associated with better weight outcomes.
The frequency spread weighing function can be constructed by applying a hyperbolic tangent function to the filter response spread value, W x = 1 2 1 + tanh λ 2 s x − c (12).
There was no significant difference between the two conditions with respect to their frequency of weighing (p = 0.16).
These variables included: medication use for overweight-related health complaints, smoking status, number of attempts to loose weight and the frequency of weighing oneself.
A secondary objective was to assess to what extent the accuracy was affected by sex, age, overweight status, SES and the health-related factors smoking status, medication use, frequency of weighing oneself and number of attempts to loose weight.
The following variables were included in the regression models as independent variables: sex, age, SES, measured weight, measured height, measured BMI, measured WC, smoking status, medication use, frequency of weighing oneself and number of attempts to loose weight.
It is conceivable that the number of attempts to loose weight and frequency of weighing oneself may also be associated with the accuracy of self-reported anthropometrics, but to our knowledge these associations have not been investigated previously.
