Attitudes towards ideal family size of different ethnic/nationality groups in Great Britain, France and Germany.

This article reports upon results from a European Union funded project on the integration of children of international migrants in Britain, France and Germany. It provides both a descriptive and a multivariate analysis of the factors that determine attitudes towards ideal family size. The results reveal that there are large differences between ethnic groups in Britain: Indian and Pakistani respondents in Britain expressed a preference for significantly larger families. However, many children of international migrants expressed a desire for smaller families than the autochthonous population in both countries. This was particularly the case for Portuguese respondents in France and Turks in Germany. Religious affiliation also had a significant effect, above and beyond ethnicity per se. Both Moslems and Christians preferred larger families than those with no religious affiliation. The article concludes that ethnic differences in attitudes towards fertility behaviour will remain important in the foreseeable future in western Europe, particularly in Britain.

Histopathologists’ approach to keratoacanthoma: a multisite survey of regional variation in Great Britain and Ireland

Introduction: This survey examines regional variation in the diagnosis of keratoacanthoma (KA).

Methods: Twenty-three departments from Great Britain and Ireland were invited. The number of cases coded as KA or cutaneous SCC in the previous 12 months was retrieved. An SCC: KA ratio was calculated. Participants also provided free text responses.

Results: Seventeen departments replied. A total of 11 718 cases were included with a breakdown of 998 KA and 10 720 SCC. The mean SCC:KA ratio was 10.7:1, range (2.5:1 to 139:1). Free text responses are presented.

Discussions: An extreme variation in approach is highlighted by this survey. We believe a multidisciplinary team approach to the diagnosis of KA is essential. There seems to be a need for a carefully considered clinicopathological study, backed up by molecular studies, to better understand the natural biology of this diagnosis.

A Note on Race, Ethnicity and Nativity Differences in Remarriage in the United States

The objectives of this study are to produce up-to-date estimates of race/ethnic/nativity differentials for remarriage and repartnership among women in the United States and to see if these differences are due to across-group differences in demographic characteristics. First, we produce lifetable estimates of remarriage and repartnering for white, black, U.S. born Latina and foreign born Latina women. Next, we estimate race/ethnic/nativity differentials for remarriage and repartnership using event-history analysis with and without controls for demographic characteristics. The results suggest a continued overall decline in remarriage rates, while many women repartner by cohabitating. Whites are more likely than blacks or Latinas to remarry and they are also more likely to repartner. Race/ethnic/nativity differentials remain even after accounting for variations in demographic characteristics. This suggests that race/ethnic/nativity differentials in remarriage and repartnering rates, rather than ameliorating disadvantages associated with divorce, reinforce these differentials.

Vitamin D and mortality: meta-analysis of individual participant data from a large consortium of cohort studies from Europe and the United States

Objective: To investigate the association between serum 25-hydroxyvitamin D concentrations (25(OH)D) and mortality in a large consortium of cohort studies paying particular attention to potential age, sex, season, and country differences.

Design: Meta-analysis of individual participant data of eight prospective cohort studies from Europe and the US.

Setting: General population.

Participants: 26 018 men and women aged 50-79 years

Main outcome measures: All-cause, cardiovascular, and cancer mortality.

Results: 25(OH)D concentrations varied strongly by season (higher in summer), country (higher in US and northern Europe) and sex (higher in men), but no consistent trend with age was observed. During follow-up, 6695 study participants died, among whom 2624 died of cardiovascular diseases and 2227 died of cancer. For each cohort and analysis, 25(OH)D quintiles were defined with cohort and subgroup specific cut-off values. Comparing bottom versus top quintiles resulted in a pooled risk ratio of 1.57 (95% CI 1.36 to 1.81) for all-cause mortality. Risk ratios for cardiovascular mortality were similar in magnitude to that for all-cause mortality in subjects both with and without a history of cardiovascular disease at baseline. With respect to cancer mortality, an association was only observed among subjects with a history of cancer (risk ratio, 1.70 (1.00 to 2.88)). Analyses using all quintiles suggest curvilinear, inverse, dose-response curves for the aforementioned relationships. No strong age, sex, season, or country specific differences were detected. Heterogeneity was low in most meta-analyses.

Conclusions: Despite levels of 25(OH)D strongly varying with country, sex, and season, the association between 25(OH)D level and all-cause and cause-specific mortality was remarkably consistent. Results from a long term randomised controlled trial addressing longevity are being awaited before vitamin D supplementation can be recommended in most individuals with low 25(OH)D levels.
