Etiology of ethnic differences in childhood spirometry

OBJECTIVES Age- and height-adjusted spirometric lung function of South Asian children is lower than those of white children. It is unclear whether this is purely genetic, or partly explained by the environment. In this study, we assessed whether cultural factors, socioeconomic status, intrauterine growth, environmental exposures, or a family and personal history of wheeze contribute to explaining the ethnic differences in spirometric lung function. METHODS We studied children aged 9 to 14 years from a population-based cohort, including 1088 white children and 275 UK-born South Asians. Log-transformed spirometric data were analyzed using multiple linear regressions, adjusting for anthropometric factors. Five different additional models adjusted for (1) cultural factors, (2) indicators of socioeconomic status, (3) perinatal data reflecting intrauterine growth, (4) environmental exposures, and (5) personal and family history of wheeze. RESULTS Height- and gender-adjusted forced vital capacity (FVC) and forced expired volume in 1 second (FEV1) were lower in South Asian than white children (relative difference -11% and -9% respectively, P < .001), but PEF and FEF50 were similar (P ≥ .5). FEV1/FVC was higher in South Asians (1.8%, P < .001). These differences remained largely unchanged in all 5 alternative models. CONCLUSIONS Our study confirmed important differences in lung volumes between South Asian and white children. These were not attenuated after adjustment for cultural and socioeconomic factors and intrauterine growth, neither were they explained by differences in environmental exposures nor a personal or family history of wheeze. This suggests that differences in lung function may be mainly genetic in origin. The implication is that ethnicity-specific predicted values remain important specifically for South Asian children.

Alles koscher? Die Erfindung eines jüdischen "ethnic food" im urbanen Kontext

Die Erfindung eines jüdischen „ethnic food“ im urbanen Kontext Die religiösen Speisegesetze, die Kaschrut, sind heute nur noch für eine kleine Minderheit der Juden im Alltag verbindlich. In urbanen Zentren Europas finden sich heute jedoch eine Vielzahl von Restaurants, die Bezug nehmen auf das Judentum und seine kulinarischen Traditionen. Am Beispiel von fünf verschiedenen Städten (Berlin, Lodz, Paris, Wien, Zürich) wird aufgezeigt, wie „jüdische“ Gastronomie vor dem Hintergrund unterschiedlicher historischer Erfahrungen und vielfältiger Migrationsbewegungen von Juden aber auch von Nichtjuden neu interpretiert werden können. Auch wenn die meisten Gaststätten keine koscheren Speisen im religionsgesetzlichen Sinne anbieten, sind diese Restaurants doch ein wichtiges Merkmal eines innovativen und integrativen Umgangs mit Europas jüdischem Erbe.

Crossing borders: Ethnic minorities matter? A meta analytic examionation of the alliance-outcome relationship

Objectives: The purpose of this meta analysis was to examine the moderating impact of substance use disorder as inclusion/exclusion criterion as well as the percentage of racial/ethnic minorities on the strength of the alliance-outcome relationship in psychotherapy. It was hypothesized that the presence of a dsm axis i substance use disorders as a criterion and the presence of racial/ethnic minority as a psychosocial indicator are confounded client factors reducing the relationship between alliance and outcome. Methods: A random effects restricted maximum-likelihood estimator was used for omnibus and moderator models (k = 94). results: the presence of (a) substance use disorder and, (b) racial/ethnic minorities (overall and specific to african americans) partially moderated the alliance-outcome correlation. The percentage of substance use disorders and racial/ethnic minority status was highly correlated. Conclusions: Socio-cultural contextual variables should be considered along with dsm axis i diagnosis of substance use disorders in analyzing and interpreting mechanisms of change.
