The Effects of Social Class and Ethnicity on Gender Differences in GCSE Attainment: A Secondary Analysis of the Youth Cohort Study of England and Wales 1997-2001

This article is based upon a secondary analysis of the Youth Cohort Study of England and Wales 1998 and examines the effects of social class and ethnicity on gender differences in GCSE attainment for those who left school in 1997 (n = 14,662). The article shows that both social class and ethnicity exert a far greater influence on the GCSE performance of boys and girls than gender. Moreover, the article also shows that an interaction effect is present between social class and gender and also between ethnicity and gender in relation to their impact upon GCSE attainment. More specifically, the findings suggest that a strong correlation exists such that the lower the overall levels of educational attainment for any group (whether that group is defined in terms of social class or ethnicity), the higher the gender differences that exist between those within that group.

Qutting and restarting smoking: cohort study of patients with angina in primary care

Objective To examine variations in self-reported smoking habit among a cohort of individuals with chronic coronary heart disease over a five year period. Design Cross-sectional cohort; interviews at baseline, 2 years and 5 years. Setting Primary care. Participants A cross-sectional sample of 688 patients previously diagnosed as having angina, identified from 18 general practices in the Greater Belfast Area; a cohort of 487 were followed for five years. Outcome measures Changes in self-reported smoking habits; breath carbon monoxide measurement. Results Initially 92 of the 487 participants (19%) reported smoking, 34 (27%) subsequently reported non-smoking. Of the 395 self-reported non-smokers at baseline, 21 (5%) subsequently reported smoking. The prevalence of self-reported smoking amongst the cohort was 19% and 15% at two and five years respectively. However, changes in reported smoking habits indicating periods of abstinence and resumption were reported by 55/487 (11%) participants. Of the 21 non-smokers who changed their report, 20 had smoked previously, five reported having stopped for less than one year but nine for more than five years. Of the initial sample twice as many smokers as non-smokers had died by 2 years (10% v 5%; p

Utilization of analgesics, sedatives, and pain scores in infants with a prolonged hospitlaization: A prospective descriptive cohort study

Aim
Describe the utilization of analgesic and sedative medications and documentation of pain scores in a cohort of critically ill infants in a neonatal intensive care unit.

Method
A prospective, longitudinal, cohort study of infants with a predicted length of stay =28 days. Dosages and routes of administration of analgesic and sedative medications and documentation of pain scores were collected on a daily basis.

Results
55 infants were enrolled into the study. Oral sucrose was administered to all 55 infants, 51 infants (93%) were administered enteral acetaminophen and 50 (91%) infants were administered morphine during their hospitalization. Sedatives were administered to 42 infants (76%); 36 (65%) were administered chloral hydrate and 32 (58%) were administered intravenous midazolam. With the exception of the first week of admission, when there was highest utilization of opioids and lower use of sucrose, acetaminophen and sedatives, the pattern of administration of analgesic and sedative agents remained relatively constant throughout the hospitalization. Pain scores were documented for 36 (65%) infants during their hospitalisation, however for these 36 infants, pain scores were infrequently recorded.

Conclusion
There was substantial and varied analgesic and sedative use in this cohort of infants, yet infrequent documentation of pain assessment scores. These practices highlight important clinical implications for sick infants requiring careful consideration of pain and distress management.
