Half the epidemiological studies with information about menopausal hormone therapy and ovarian cancer risk remain unpublished, and some retrospective studies could have been biased by selective participation or recall. We aimed to assess with minimal bias the effects of hormone therapy on ovarian cancer risk.
Special studies and isolated initiatives over the past several decades in low-, middle- and high-income countries have consistently shown inequalities in health among socioeconomic groups and by gender, race or ethnicity, geographical area and other measures associated with social advantage. Significant health inequalities linked to social (dis)advantage rather than to inherent biological differences are generally considered unfair or inequitable. Such health inequities are the main object of health development efforts, including global targets such as the Millennium Development Goals, which require monitoring to evaluate progress. However, most national health information systems (HIS) lack key information needed to assess and address health inequities, namely, reliable, longitudinal and representative data linking measures of health with measures of social status or advantage at the individual or small-area level. Without empirical documentation and monitoring of such inequities, as well as country-level capacity to use this information for effective planning and monitoring of progress in response to interventions, movement towards equity is unlikely to occur. This paper reviews core information requirements and potential databases and proposes short-term and longer term strategies for strengthening the capabilities of HIS for the analysis of health equity and discusses HIS-related entry points for supporting a culture of equity-oriented decision-making and policy development.
This volume brings together a number of papers which have used the OPCS Longitudinal Study to investigate relationships between employment occupation social characteristics and subsequent mortality [in England and Wales]. Data for the studies are also taken from the 1971 and 1981 censuses and the National Health Service Central Register. (EXCERPT)
Summary The OPCS Longitudinal Study has been used to study both overall and cause-specific mortality patterns in 1971–1981 among men and women directly or indirectly affected by unemployment in April 1971. Groups studied included men seeking work in 1971, the wives of men seeking work in 1971 and other women in the same households as a man seeking work in 1971. The findings of this project are summarized here and attention is focused on mortality from circulatory diseases, in particular ischaemic heart disease. The study provides evidence which could be seen as supporting hypotheses about relationships between stress and overall mortality, with a marked excess for suicides. The evidence with respect to ischaemic heart disease is positive but less convincing with excess mortality from this cause principally occurring among younger unemployed men and among the wives of men who were seeking work in 1971. Given the sharp contrasts in the pattern and levels of unemployment between 1971 and 1981 it is difficult to extrapolate from these findings to the present day.
Objective To investigate the relation between women’s reported use of breast and cervical screening and sociodemographic characteristics. Design Cross sectional multipurpose survey. Setting Private households, Great Britain. Population 3185 women aged 40-74 interviewed in the National Statistics Omnibus Survey 2005-7. Main outcome measures Ever had a mammogram, ever had a cervical smear, and, for each, timing of most recent screen. Results 91% (95% confidence interval 90% to 92%) of women aged 40-74 years reported ever having had a cervical smear, and 93% (92% to 94%) of those aged 53-74 years reported ever having had a mammogram; 3% (2% to 4%) of women aged 53-74 years had never had either breast or cervical screening. Women were significantly more likely to have had a mammogram if they lived in households with cars (compared with no car: one car, odds ratio 1.67, 95% confidence interval 1.06 to 2.62; two or more cars, odds ratio 2.65, 1.34 to 5.26), and in owner occupied housing (compared with rented housing: own with mortgage, odds ratio 2.12, 1.12 to 4.00; own outright, odds ratio 2.19, 1.39 to 3.43), but no significant differences by ethnicity, education, occupation, or region were found. For cervical screening, ethnicity was the most important predictor; white British women were significantly more likely to have had a cervical smear than were women of other ethnicity (odds ratio 2.20, 1.41 to 3.42). Uptake of cervical screening was greater among more educated women but was not significantly associated with cars, housing tenure, or region. Conclusions Most (84%) eligible women report having had both breast and cervical screening, but 3% report never having had either. Some inequalities exist in the reported use of screening, which differ by screening type; indicators of wealth were important for breast screening and ethnicity for cervical screening. The routine collection within general practice of additional sociodemographic information would aid monitoring of inequalities in screening coverage and inform policies to correct them.
Raleigh says that ethnic origin is not known for sentinel outcomes—such as the 636 000 births and 470 000 deaths annually in England.1 However, we have just published data by ethnic group on all births in England and Wales in 2005.2 Like the …
Objective To assess the feasibility and acceptability of randomizing the phased introduction of the extension of the invited age range in the National Health Service (NHS) Breast Screening Programme in England from 50-70 to 47-73 years. Setting Six volunteer breast screening units (BSUs) in England. Methods Cluster-randomized trial of invitation versus no invitation for breast screening. Study participants: women aged 47-49 and 71-73 years in screening batches randomized between 1 June 2009 and 31 May 2010. Outcomes: workload, screening uptake among women invited, self-referrals among women not invited, and screening outcomes among women invited. Results A total of 312 screening batches (clusters) were randomized including 60,708 women. Screening uptake was 63% in women aged 47-49 and 62% in women aged 71-73. Those who attended screening in the younger age group were more likely to be recalled for assessment than older attendees (7.5% vs. 3.0%) but less likely to be diagnosed with breast cancer (0.5% vs. 1.1%). Among women not invited, 0.2% of those aged 47-49 and 6.8% of those aged 71-73 self-referred for screening. Despite the extra workload BSUs largely coped although there was some slippage in round lengths and other targets. Conclusion No major problems of feasibility or acceptability of randomization were found. This pilot study has informed the randomized phasing-in of the age extension across the whole of England.
