Uptake of breast screening is influenced by current religion and religion of upbringing

Research has shown that individuals with a current religious affiliation are more likely to use preventive health services. The aim of this study was to determine whether breast screening uptake in Northern Ireland is higher amongst women with a current affiliation to an organised religion and, for those with no current affiliation, to examine whether their religion of upbringing is associated with uptake of breast screening. The Northern Ireland Longitudinal Study (NILS) was used to link Census and national breast screening data for 37,211 women invited for routine breast screening between 2001 and 2004. Current religious affiliation, religion of upbringing and other demographic and socio-economic characteristics were as defined on the Census form. Multivariate logistic regression was used to determine the relationship between religion affiliation and attendance. Uptake of breast screening is about 25% lower for those without a current religious affiliation. There are modest differences between Catholics and Protestants, with the latter about 11% more likely to attend for screening. For those with no current religion, the religion of upbringing appears to positively influence attendance rates. These differences remain after adjustment for all of the socio-demographic and socio-economic factors that have been shown to influence uptake rates of breast screening in the UK to date. Record linkage is an efficient way to examine equity across demographic characteristics that are not routinely available. The lower uptake amongst those with no religious affiliation may mean that screening services may find it difficult to maintain or improve uptake rate in an increasingly secularised society.

Coeliac disease detected by screening is not silent--simply unrecognized

Coeliac disease (CD) is associated with a wide spectrum of clinical presentation and may be overlooked as a diagnosis. There is some evidence that untreated CD is associated with a doubling of mortality, largely due to an increase in the incidence of malignancy and small intestinal lymphoma, which is decreased by a strict gluten-free diet. We studied the clinical features of screening-detected coeliacs compared to age- and sex-matched controls as a 3-year follow-up to a population screening survey, and followed-up subjects who had had CD-associated serology 11 years previously to determine whether they have CD or an increased mortality rate compared to the general population. Samples of the general population (MONICA 1991 and 1983) were screened for CD-associated serology and followed-up after 3 and 11 years, respectively, and assessed by a clinical questionnaire, screening blood tests and jejunal biopsy. Mortality rates for 'all deaths' and 'cancer deaths' were compared in subjects with positive serology in 1983 with reference to the general population. Thirteen coeliacs were diagnosed by villous atrophy following screening, compared to two patients with clinically detected CD, giving a prevalence of 1:122. Clinical features or laboratory parameters were not indicative of CD compared to controls. Subjects with positive serology followed up after 11 years did not have an excess mortality for either cancer deaths or all causes of death. Screening-detected CD is rarely silent and may be associated with significant symptoms and morbidity. In this limited study with small numbers, there does not appear to be an increased mortality from screening-detected CD, although the follow-up may be too short to detect any difference.
