Physical inactivity as we intend to study physical inactivity in relation to alienation, and four potential confounders of this association: sex, age group, socio-economic position (SEP) and migration status [34, 35].
Those pursuing the sources project and the variation project also aim to determine which factors co-vary with answers cultural or ethnic group, socio-economic status, region of brain or cognitive processes implicated in answering the question, psychopathology, order of questions, framing of questions, etc.
Adjustment for year, gender, age group, socio-economic deprivation and co-morbidity led to an 8% higher odds ratio of death for the second week (OR 1.08, 95% CI 1.01 to 1.16, p = 0.03) (Table 2).
Adjustment for year, gender, age group, socio-economic deprivation and co-morbidity led to a 6% higher odds ratio of death for the second week (OR 1.06, 95% CI 1.00 to 1.13, p = 0.05).
As in the 65-74 agroupoup, socio-economic status did not modify the effect.
All individuals are registered with an ID-number, age, sex, ethnic group, socio-economic characteristics and twin status.
Secondly, these ORs were adjusted for other factors in the same group (socio-demographic, antenatal and birth, postnatal support).
Records with missing sex, ethnic group, socio-economic class, SHA or age group were excluded from the analysis because of the unavailability of a comparable population denominator.
All models adjusted for baseline dietary behaviour, age, sex, randomization group, socio-economic status, change in smoking status, change in self-reported total physical activity levels, change in alcohol consumption, and change in medication where applicable.
Data were directly standardized against the whole state (2001) for gender, 10 year age group, socio-economic status, and region of residence (urban, suburban, outer metropolitan, regional, rural and remote).
The categorical variables (gender, age group, socio-economic and smoking status) were entered as fixed factors and the continuous variables (time spent at various types of exercise) were incorporated as continuous linear covariates.
