These 3 groups were: low (educational level 0 2), middle (educational level 3 4), and high (educational level 5 6) (http://www.unesco.org).unesco.org
The authors used Cox proportional hazards modelling to estimate HRs for total mortality controlling for age, centre, sex, educational level, body mass index, physical inactivity, smoking, insulin treatment, hypertension, hyperlipidaemia and history of myocardial infarction, stroke or cancer.
The inclusion criteria included children aged 3 18 diagnosed with CP in educational centres, regardless of educational level.
We also took into account a number of personal characteristics of the childbearing women, such as parity (0 = primiparous; 1 = multiparous), age in years (centred around grand mean) and educational level (0 = no higher education; 1 = higher education).
There were no significant differences between the recruitment centres in terms of subject age and educational level, numbers of borderline criteria and in/outpatient ratio.
A secondary analysis adjusted for recruitment centre and the potentially important prognostic baseline factors of cigarette dependence, age, depression, maternal educational level, and partner's smoking status.
In Tables 3 and 4, age is a continuous variable centred at 67 years (agec).> -wrap-foot>> -wrap-foot> Model II is also adjusted for educational level, BMI, and self-reported health.
People with an educational level of high school or higher are more likely to use free services from a day care centre but less likely to use services from a nursing centre.
Models stratified by centre, age, and follow-up time, and adjusted by total energy intake, plausibility of energy reporting, alcohol intake, smoking status, educational level and recreational physical activity.
