Neonatal mortality during the first week of life, corresponding to years 1975–1998, was studied in Spain. The life is time which highest number deaths occur. temporal decrease neonatal rate (NMR) modelled according log 10 (NMR+1)= 2·784−0·023 per year. This decline cannot be explained by an increase mean birth weight (MBW=23440·835−10·107 g year). From most frequent causes death least were: congenital anomalies, preterm born or low weight, respiratory problems, pregnancy difficulties,...

Abstract The variation of 18 Alu polymorphisms and 3 linked STRs was determined in 1,831 individuals from 15 Mediterranean populations to analyze the relationships between human groups this geographical region provide a complementary perspective information studies based on uniparental markers. Patterns population diversity revealed by two kinds markers examined were different one another, likely relation their mutation rates. Therefore, while biallelic underlies general heterogeneity...

Based upon 303 students from the Complutense University at Madrid (100 males and 203 females), aged between 21 29 years, results of nine anthropometric measurements four strength tests were evaluated. Males females analyzed separately in order to determine whether relationship body typology physical performance varies according gender. Regarding strength, maximum gender differences observed for pulling (females: 53% male values), followed by hand grip (59%) vertical jump (66%). In general,...

The increased incidence of multiple deliveries in Spain, addition to changes age at maternity and parity, is attributed assisted reproductive treatments, but the relative contribution latter this rise remains uncertain, due scarce information provided by clinics practicing those treatments. Population based data (1984-2004), including on mother's age, nationality, marital status, date delivery, characteristics each (parity, single or multiple), sex newborns were Spanish Institute Statistics....

Background: Low weight and premature deliveries arouse clinical interest concerning the survival of newborns. The determinants birth among Spanish natives immigrants may differ. Research which considers maternal origin associated factors such as age parity is important.

In a population the inbreeding coefficient ;ga is determined by relative incidence of various degrees consanguineous marriages—uncle-niece or aunt-nephew (C12), first cousin (C22), once removed (C23), second (C33)—which may be related to temporal, geographic, demographic, and economic factors. Using published information from Spain corresponding urban rural areas, in this article we seek establish how each specific relationship behaves with respect socioeconomic factors, determine...

Summary The geographic and demographic dimensions of Spain, in terms surface number inhabitants, its heterogeneous socioeconomic development offer an adequate opportunity to study the provincial differences birth weight from 1996 2010, focusing on possible factors determining relative frequency low weight. analysed with regard biological, that interfere female reproductive pattern. variables considered here were: order, proportion premature deliveries, mother's age, multiparity, country...

The present paper is based on information marital patterns and reproductive performance (reconstituted families) in the rural community of Los Nogales, Galicia, Spain. Biodemographic data were used to analyse temporal changes structure consanguinity population, as well versus success. Of 2347 marriages celebrated between 1871 1977, 5.15% relatives (up third degree). population's inbreeding coefficient was above Spanish average after 1890, levels high during first part 20th century. A...

Information on consanguinity in Spain was reanalyzed order to obtain a more complete picture of patterns by considering temporal, geographical, demographic, and economic factors. To data consanguineous marriages, we reviewed 106 published references. Only populations with homogeneous geographical characteristics, activities, transportation facilities, the like, were considered. Two-way analysis variance (ANOVA) provided highly significant differences (p < 0.001) for both time periods urban...

Background: This analysis focuses on determining differences in the risk of stillbirth Spain by comparing native and foreign mothers with regard to bio-demographic factors.

Among determinants of the structure human populations, consanguineous marriages can be useful in determining to what extent they influence genetic population. This knowledge may gained by comparing reproductive performance related and non-related couples. The population studied, La Cabrera, is a mountainous region Leon province (north-western Spain). It includes four neighbouring municipalities with similar geographic, climatic ecological features 37 parishes occupying an area 784.2 km(2),...

The objective of this paper is to analyse temporal birth weight variation, its relationship the frequency premature births in Portugal, and influence native immigrant mothers' characteristics as well determine possible existence a pattern change Iberian Peninsula whole. Individual mother-child data from Portuguese National Institute Statistics regarding live (N = 2,661,542) permitted an analysis, for first time, at Portugal bio-demographic perspective. results obtained show that 1988 2011...

Abstract Measurements of stature and biacromial bicristal diameters were obtained for two samples young adult male university students, one from 1901 to 1919 the other 1989 1991. Means standard deviations calculated each measurement three indices. Significant positive trends in apparent between samples: 7.3 cm (4.4%), 3.6 (9.9%), 3.4 (12.5%), respectively. The results compared with Spanish beginning century present. These comparisons also showed secular changes, although differences among...

The application of the isonymic method to establish interpopulation relationships is made difficult by such factors as: (1) a small population size; (2) subdivision into ethnosocial groups; and (3) existence individuals born extramaritally. present study analyzes validity isonymy in populations where difficulties exist. Lasker's Rij relationship coefficients were calculated base marital records from six Pocho parishes (Argentina) for period 1766 1840. Three endogamous groups...

Surnames analysis is useful for populations in which only written documents remain, as the case historical populations. In Córdoba province, Argentina, census records contain nominal data of inhabitants, including information on sex, age, ethnosocial category, civil status, occupation, place birth, and residence, that can be analyzed using surnames. Relationship indicators within among ecclesiastic units were estimated by isonymy adult white population registered 1813 census. The Rii, Rij,...

Background . The purpose of this paper is to determine the relative mortality risks at delivery and during first week life with regard maternal foetal characteristics. Methods Yearly individual digital records on live births early neonatal were used infer possible factors involved in perinatal deaths. Results results show that number per year declined time throughout period studied. At same time, rates decreased 66.4% for stillbirths 70.2% mortality. Logistic regressions modelled interaction...

Summary The present analysis compares the distribution of surnames by means spatial autocorrelation in Spain–Portugal border region. Spanish National Institute Statistics provides a database residents western provinces Zamora, Salamanca, Cáceres, Badajoz and Huelva. Portuguese patterns surname were established according to various geographic axes. results obtained show low diversity this region – especially centre which can be explained absence any major barriers, with exception mountain...

Summary The reproductive pattern of a sample nuclear families from La Alpujarra (Andalusia, Spain) is analysed. origin the wife or consanguinity couple does not influence fertility. Variability in number pregnancies most closely associated with marriage duration followed by wife's year birth. Differences births are explained more than miscarriages. survivors to first birthday dependent on and lower extent infant mortality. Data incomplete show that performance below age 45 cannot be accepted...

Abstract Temporal variations in the frequency of multiple maternities many Western European countries have been described. However, within a single country, regional differences are observed. Urban industrialized regions and rural agricultural areas experienced recent decades distinct decline deliveries, which cases related to maternal age parity changes. Research on deliveries Spain is scarce none studies go back beginning 20th century or consider variation over an extended period time. The...

The incidence of dermatoglyphic finger patterns and pattern intensity in a sample school children from the Alberche/Tormes valley (northern slope Sierra de Gredos, Central Spain) are described. Significant bilateral differences for overall found both sexes. between sexes also statistically significant, except left hand. Pattern Intensity Index significantly differs hands males only, sex not significant. Variation ranges fingertip were constructed using published data 69 male 62 female series...

The seasonality of births in the period 1871-1977 is studied a rural north-western Spanish population. Based on total sample 11,695 birth registrations, temporal variation analysed. For siblings, according to family reconstitution, size, legitimacy child, and order are considered. A coefficient month dispersion defined estimated for each family. Intra-family related inter-family coefficients determine whether local seasonal pattern may be partly explained by characteristics.The 1971 through...
