We included the following social behavioural variables to study the relationship between smoking and drinking behaviours of students: their best friends' and peer group's health behaviours.
Finally, although there were several significant correlations between immune parameters and behavioural variables, the results were inconsistent with the hypothesis that immune status and personality are related in the budgerigar.
To quantify the differences between sequences along these behavioural variables, we computed the accuracy of multivariate classification of the nine trained sequences (overall classifier), using maximum forces at each of the five fingers as different data features instead of voxel activity.
All behavioural variables in the 'short-term adult' group were highly correlated between the first and second test (Spearman rank correlations, all rs > 0.34, all p < 0.001; details of correlation, mean and SD present in Table 1).
Behavioural variables of the two tests were correlated with each other.
All dichotomous behavioural variables referred to the six-month period prior to the interview.
The relationship between socio-demographic or behavioural variables, dental status and the COHIP scores were also studied.
Thus it is essential that relevant background and behavioural variables, which may confound the association between periodontitis and psoriasis, are taken into account, however, to our knowledge, no previous studies controlled for socioeconomic status (education) of participants or dental attendance.
Social behavioural factors were still better predictors than social psychological variables, but the correlations between social behavioural variables and health risk behaviours are weaker.
Regression coefficients and 95% CIs were used to estimate the association between sociodemographic and behavioural variables at baseline (independent variables) and the change in BMI z-score and in BF% (follow-up minus baseline).
