[Percentile Values for the Anthropometric Dimensions of Triplet Neonates - Analysis of German Perinatal Survey Data of 2007-2011 from all States of Germany]. / Perzentilwerte für die Körpermaße neugeborener Drillinge - Ergebnisse der deutschen Perinatalerhebung der Jahre 2007-2011 unter Beteiligung aller Bundesländer.

AIM: We aimed to develop national reference values for birth weight, length, head circumference, and weight for length for newborn triplets based on data from the German perinatal survey of 2007-2011. MATERIAL AND METHODS: Perinatal survey data of 3,690 newborn triplets from all the states of Germany were kindly provided to us by the AQUA Institute in Göttingen, Germany. Data of 3,567 newborn triplets were included in the analyses. Sex-specific percentile values were calculated using cumulative frequencies. Percentile values at birth were computed for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles for 21-36 completed weeks of gestation. RESULTS AND CONCLUSIONS: We present the first German reference values (tables and curves) for the anthropometric dimensions of triplet neonates and compare selected birth weight and length percentiles of triplets (after 32 and 34 completed weeks of gestation) to those of singletons and twins. The differences in the 50th birth weight percentiles between singletons and triplets after 32 completed weeks of gestation were 180 g for girls and 210 g for boys; after 34 weeks of gestation the differences were 320 and 325 g, respectively. The differences between twins and triplets after 32 weeks of gestation were 100 g for girls and 120 g for boys; after 34 weeks of gestation they were 130 and 135 g, respectively. The data presented here enable the classification of newborn triplets according to somatic parameters making reference to German perinatal data.

The Pan-University Network for Global Health: framework for collaboration and review of global health needs.

In the current United Nations efforts to plan for post 2015-Millennium Development Goals, global partnership to address non-communicable diseases (NCDs) has become a critical goal to effectively respond to the complex global challenges of which inequity in health remains a persistent challenge. Building capacity in terms of well-equipped local researchers and service providers is a key to bridging the inequity in global health. Launched by Penn State University in 2014, the Pan University Network for Global Health responds to this need by bridging researchers at more than 10 universities across the globe. In this paper we outline our framework for international and interdisciplinary collaboration, as well the rationale for our research areas, including a review of these two themes. After its initial meeting, the network has established two central thematic priorities: 1) urbanization and health and 2) the intersection of infectious diseases and NCDs. The urban population in the global south will nearly double in 25 years (approx. 2 billion today to over 3.5 billion by 2040). Urban population growth will have a direct impact on global health, and this growth will be burdened with uneven development and the persistence of urban spatial inequality, including health disparities. The NCD burden, which includes conditions such as hypertension, stroke, and diabetes, is outstripping infectious disease in countries in the global south that are considered to be disproportionately burdened by infectious diseases. Addressing these two priorities demands an interdisciplinary and multi-institutional model to stimulate innovation and synergy that will influence the overall framing of research questions as well as the integration and coordination of research.

[New percentile values for the anthropometric dimensions of singleton neonates: analysis of perinatal survey data of 2007-2011 from all 16 states of Germany]. / Neue Perzentilwerte für die Körpermaße neugeborener Einlinge: Ergebnisse der deutschen Perinatalerhebung der Jahre 2007-2011 unter Beteiligung aller 16 Bundesländer.

AIM: The aim of this study was to derive percentile values for birth weight, length, head circumference, and weight for length for singleton neonates based on the German perinatal survey of 2007-2011 (using data from all 16 states of Germany). We also compared these new percentile values with the percentile values of 1995-2000 that so far have been considered standard values. MATERIAL AND METHODS: Data of 3 187 920 singleton neonates from the German perinatal survey of the years 2007-2011 were kindly provided to us by the AQUA Institute in Göttingen, Germany. Sex specific percentile values were calculated using cumulative frequencies. Percentile values at birth were computed for the 3(rd), 10(th), 25(th), 50(th), 75(th), 90(th), and 97(th) percentiles for 21-43 completed weeks of gestation. Percentile curves and tabulated values for the years 2007-2011 were compared with the published values of 1995-2000. RESULTS AND DISCUSSION: Overall the new percentile curves closely resemble the previous ones. Minimal differences can be found for the 10(th) percentile and generally for early weeks of gestation. Values for the 10(th) percentile in the 2007-2011 dataset are somewhat higher than values of 1995-2000 for birth weight, length, and weight for length. CONCLUSIONS: We recommend the use of these new percentile values instead of the old ones.

[Changes in the somatic classification according to birth weight and duration of pregnancy of newborn girls when maternal height is considered]. / Veränderungen in der somatischen Klassifikation weiblicher Neugeborener nach Geburtsgewicht und Schwangerschaftsdauer unter Berücksichtigung der Körperhöhe der Mutter.

This study examines the quantitative changes in the somatic classification according to birth weight and duration of pregnancy of German neonates when maternal height is considered (5 maternal height groups). Our calculations were performed using data of 319 884 girls born in 2010. Overall, about 6% (18 792 girls) are classified differently (more appropriately) when group-specific norm values were used.

Analysis of the German perinatal survey of the years 2007-2011 and comparison with data from 1995-1997: neonatal characteristics and duration of pregnancy.

BACKGROUND AND AIM: We have previously analysed neonatal characteristics and duration of pregnancy in Germany based on data from the German Perinatal Survey of 1995-1997. Here we describe neonatal characteristics and duration of pregnancy based on the German Perinatal Survey of 2007-2011. MATERIAL AND METHODS: We had been provided with data from the German Perinatal Survey of 1995-1997 by the chambers of physicians of all the states of Germany except Baden-Württemberg (1 815 318 singleton neonates). We were also provided with access to the perinatal survey data of 2007-2011 by the AQUA Institute in Göttingen, Germany (3 187 920 singleton neonates). We investigated regional differences within Germany and also compared the 2 periods of time. We used the computer programme SPSS for data analysis and performed plausibility checks on the survey data. RESULTS: Comparing the states of Germany, we found that birth weight was largest for neonates born in Schleswig-Holstein (3 407 g) and Mecklenburg-Western Pomerania (3 392 g); the lowest mean birth weight was observed in the Saarland (3 283 g). Preterm birth rate varied between 6.3% (Saxony) and 8.1% (Bremen, Saarland). Comparing 1995-1997 vs. 2007-2011, deliveries after 37 and 38 weeks of gestation were more common and deliveries after 39 and more weeks of gestation were less common in the later period of time. CONCLUSIONS: Regional differences in the anthropometric characteristics of neonates exist between the states of Germany. The proportion of deliveries after 39 and more weeks of gestation has decreased.

Diversity in auxology: between theory and practice. Proceedings of the 18th Aschauer Soiree, 13th November 2010.

Auxology has developed from mere describing child and adolescent growth into a vivid and interdisciplinary research area encompassing human biologists, physicians, social scientists, economists and biostatisticians. The meeting illustrated the diversity in auxology, with the various social, medical, biological and biostatistical aspects in studies on child growth and development.

Sex-specific differences in birth weight due to maternal smoking during pregnancy.

INTRODUCTION: We investigated the sex-specific risk of maternal smoking during pregnancy on the birth weight and the proportion of small-for-gestational-age (SGA) newborns in 888,632 (49.9%) of 1,815,318 singleton births (ca. 80% of all singleton births in Germany from 1995 to 1997) in whom data on maternal cigarette consumption were available. RESULTS AND DISCUSSION: Newborns below the 10th percentile for weight and duration of pregnancy were classified SGA. Maternal smoking during pregnancy lowers the mean birth weight and increases the risk of SGA newborns. The negative effect depends on the daily number of cigarettes consumed, and is greater in girls than in boys. In non-smokers, 9.8% of the newborns were SGA, with a sex-ratio of females:males=1, but this percentage increased with increasing number of cigarettes consumed (p<0.001), as did the sex-ratio, i.e. the negative effect of smoking on growth was greater in girls than in boys. In mild smokers (1-5 cigarettes/day), the risk of giving birth to an SGA girl was 1.7275-fold (95% CI: 1.7266-1.7284) above normal, but was 1.7143-fold (95% CI: 1.7137-1.7150) in boys. More than 21 cigarettes/day increased the risk of SGA 3.15-fold for a boy, but 3.51-fold for a girl (p<0.001). CONCLUSION: In conclusion, particularly in heavy smokers, the negative effect of maternal smoking during pregnancy on the mean birth weight and risk of SGA is significantly greater in newborn girls than in newborn boys.

[Comparative studies of the population structure of a Kurd village population of Southeast Turkey. II. Morphologic differentiation within the population]. / Vergleichende Untersuchungen zur Populationsstruktur einer kurdischen Dorfbevölkerung in der Südosttürkei. II. Morphologische Binnendifferenzierung.

A small scale village society from southern Turkey has been investigated by demographic, social and anthropological criteria. An internal differentiation of the population on the basis of demographic and social data could be verified for morphological features, too. This is shown clearly by a differentiation of the population into two family complexes. The consequences for the interpretation of metrical random sample surveys in typological investigations are discussed.
