A total of 1791 persons of both sexes, aged from 3 to 80 years were under study. A total of 20 somatic and physiological traits were considered. According to the data of the Central Statistical Office (available from 1976) the birth rate in Jastarnia increased in 1987 but mortality increased even at a higher rate so that the increase of the population (per 1000 inhabitants) was reduced from 6.8 in 1976 to 3.7 in 1987. A factor analysis, used to estimate socio-economic conditions of two generations of this town, has shown that the apartment size and income of a family (factor 1) explained the highest percentage of the variance of the traits considered. Education of parents was on the second position (factor 2). The next factor (3) represented biological properties of parents measured by their stature. The last one (factor 4) characterized family size in the second generation, for the first generation this trait being related with factor 2 (culture). A tendency to slim body was observed in children and youth. However, the ratio of chest circumference to stature (Marty index) did not change, which can be explained in terms of the adaptation to maritime climate. The content of adipose tissue increased in children and youth, and also the vital capacity of lungs in relation to stature (Ziemssen index) increased in children. Blood pressure at rest was reduced in 1987, but systolic blood pressure at work was increased. An increase in the minute respiration rate and reduction of chest extension in the contemporary youth seem to be rather unfavorable.","PeriodicalId":77401,"journal":{"name":"Studies in human ecology","volume":"10 ","pages":"187-206"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12518788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Latent factors in body build of newborns.","authors":"A Antoszewska","doi":"","DOIUrl":"","url":null,"abstract":"The paper is focused on relationships between traits of newborns and on discerning factors characterizing newborns more generally than individual traits. For this purpose a factor analysis was made using 35 somatic traits of 1013 newborns examined in hospitals of Zambrów and Białystok. Main components were found from the correlation matrix, and after the orthogonal rotation of the Varimax type, eight independent factors were identified. The body weight was highly correlated with circumferences of chest, calf, forearm, head, and arm. Body length was correlated with the length of lower extremities, the length of upper extremities was correlated with the length of arm and with the breadth and depth of chest, circumferences of different body parts were correlated with each other, and this was also the case of the thickness of three skin-fat-folds. The following factors were found as a result of the factor analysis (in parentheses there are traits showing highest correlations with a given factor, thus, most suitable for monitoring studies): F1-body weight (thigh circumference), F2-upper extremity length, F3-subcutaneous fat tissue (skin-fat-fold thickness on rib 10), F4-face length and nose diameters (upper-face height), F5-scapular-arm-hip diameters (scapular breadth), F6-trunk length (trunk length), F7-body length (length of lower extremities), and F8-head breadth diameters (mandible breadth).","PeriodicalId":77401,"journal":{"name":"Studies in human ecology","volume":"10 ","pages":"51-62"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12517889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a set of motor tests described elsewhere and examining the static and explosive muscular strength, agility, coordination and persistent fitness. The study objects were the generations of parents and their children (because of age-dependent differences, the traits of the latter were expressed in T-scores). Factor analysis with rotation Varimax was used to examine family traits. Four latent factors characterizing families were identified. Factor 1 (F1) was related with culture (consciousness). It explained 26% of the variance. F2 described living conditions and explained 22% of the variance. F3 (maternal-genetic) explained 12% of the variance, and factor 4 (father's genetic factor) explained 11% of the variance. These factors have a stronger effect on the motor traits of parents than on those of their children. The two generations were more similar with respect to such traits as the static strength, flexibility, spatial orientation and persistence. They were little similar with respect to explosive power and running agility. A moderate similarity occurred for throw accuracy and body balance. The most important factor in the parental generation is the consciousness (culture level) co-occurring with fitness (only for throw accuracy these were living conditions). The most important factors in the descendant generation were usually beyond the examined family traits. The present results show that in parallel to genetic and maternal factors also cultural factors related to traditional customs and social practices determine motor traits of children.","PeriodicalId":77401,"journal":{"name":"Studies in human ecology","volume":"10 ","pages":"243-94"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12518793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
