Nas últimas décadas, transformações políticas, sociais e econômicas alteraram as configurações do mundo do trabalho. A carreira, antes baseada em modelos organizacionais hierárquicos, começou a ser compreendida em termos da percepção individual sobre a sequência de experiências de trabalho no decorrer da vida. Se antes era possível estudá-la a partir de grandes escolhas iniciais, o foco passou a incidir sobre as decisões tomadas continuamente, ao longo de toda a carreira. Frente a esse cenário, surgiu uma demanda por estudos multidisciplinares que permitissem compreender a influência de fatores individuais sobre as decisões de carreira. A Psicologia Individual de Alfred Adler, com sua abordagem teleológica e de ênfase à subjetividade dos indivíduos, apresentou-se como uma perspectiva teórica adequada para esse fim. Dentre os constructos da Psicologia Individual, este estudo empregou a ordem de nascimento, em duas conceituações: posição do indivíduo na ordem de sucessivos nascimentos em sua família (ordem cronológica de nascimento) e interpretação do indivíduo para sua situação no quadro familiar (ordem psicológica de nascimento). Com o propósito de ampliar o conhecimento acerca dos motivos na tomada de decisão...

A suinocultura moderna tem se destacado pelos altos índices produtivos alcançados. Muito disso se deve à intensa tecnificação, fazendo com que as linhagens de fêmeas suínas fossem melhoradas geneticamente tornado-as hiperprolíficas. Este aumento possibilitou uma melhor produtividade e maior ganho econômico. Entretanto, houve o surgimento de problemas relacionados à desuniformidade das leitegadas, contribuindo com uma maior variabilidade de peso dentro delas. Outro fator importante e intrínseco a este, é em relação à viabilidade e vitalidade de leitões menos favorecidos, em virtude de seu baixo peso ao nascimento e possível exposição a eventos estressantes durante o parto. Em busca de possíveis explicações sobre estes problemas gerados em termos produtivos esta tese foi desenvolvida sob a forma de uma revisão literária e dois experimentos. O Trabalho 1 teve como objetivo subsidiar teoricamente a execução tanto do segundo quanto do terceiro experimento, uma vez que foram descritos os principais fatores que afetam o peso do leitão ao nascimento. Após a compilação destes dados surgiu a idéia de realizar dois experimentos complementares a este estudo inicial. O Trabalho 2 teve como objetivo avaliar o efeito de algumas variáveis medidas em leitões logo após o nascimento em relação à sua sobrevivência durante a primeira semana de vida e desenvolvimento posterior até desmame. Foram utilizados 612 leitões oriundos de 56 fêmeas de ordem de parto 3 a 5 as quais o parto foi induzido. Logo após o nascimento foram medidos os seguintes parâmetros: Frequencia cardíaca (FC)...

Foram acompanhados 575 partos para avaliar a influência da ordem de nascimento, do sexo e do peso dos leitões na ocorrência de natimortos. Dos 7061 leitões, 90,2%, 6,0% e 3,8% nasceram vivos, natimortos ou mumificados, respectivamente. O percentual de partos com natimortos foi 44,5%. Partos com dois ou mais natimortos foram responsáveis por 63,1% das perdas por natimortalidade, embora tenham sido responsáveis por 17,2% das leitegadas. O percentual de natimortos aumentou com a ordem de nascimento; a maior taxa de natimortos, 21,7%, ocorreu a partir da 14ª ordem. A taxa de natimortalidade foi de 3,6% e 10,1% nos leitões de primeira a nona e de 10ª a 13ª ordem, respectivamente. Em leitões com até 500g a taxa de natimortos foi de 52,1%, mais alta que a de leitões mais pesados. Em leitões com 501 a 1200g foi de 10,1%, maior que entre os com mais de 1200g (4,0%). Não houve efeito de sexo dos leitões na ocorrência de natimortos, que foi de 6,2% e 5,8% para machos e fêmeas, respectivamente. A natimortalidade é maior entre os leitões com baixo peso ou com ordem de nascimento elevada.; To examine the influence of birth order, gender, and birth weight of piglets on stillbirth, records of 575 farrowings were analyzed.

The objective of this study was to determine whether birth weight of the pig is related to its birth order. The study involved 292 sows from 2 genotypes (Large White x Landrace crossbred (LL), n= 247 and Alentejano (AL), n=45) of mixed parity and their piglets. Most sows farrowed naturally. Each piglet was identified, weighed (± 1g) (mummies excepted) and its birth order (BO) recorded within 2 min of birth. A total of 3418 LL and 375 AL piglets were born of which 43 and 7 were mummified, and 205 and 6 were stillborn, respectively. Number of total born (TB) and born alive piglets (BA) per litter ranged from 6 to 23 (mean, 13.85 ± 0.19 (se)) and from 6 to 22 (mean, 12.84 ± 0.17), and from 4 to 13 (mean, 8.33 ± 0.31) and from 4 to 12 (mean, 8.04 ± 0.31) in LL and AL litters, respectively. Within-litter regression was used to determine the relationship between BO and birth weight (PASW Statistics, version 18.0, 2009). To compare litters of different sizes, BO was expressed as relative BO (RBO) calculated as RBO = (BO-1) / (TB-1). The slopes of the regression lines relating birth weight of TB or BA piglets to RBO were positive and similar in both genotypes (P>0.50). The common slopes of the regression line relating birth weight of TB and BA piglets to RBO were: bTB = 70 ± 14 (g) RBO (P<0.0001...

A survey of the 20 698 singleton births occurring in one year to women resident in the Greater Dublin area provided information on birth weight, birth order, and social class. Low (less than or equal to 2500 g), suboptimal (less than or equal to 3000 g), and optimal (3001-4499 g) birth weights all showed a linear relation with social class. The incidence of low and suboptimal birth weight was highest in first, fifth, and subsequent births, and conversely optimal weight was commonest in second, third, and fourth births. Analysis indicated that a major part of the birth-order effect was attributable to social class. Birthweight categories give information which may be distorted when using mean weight alone. The ue of suboptimal and optimal weight offers the possibility of more accurate assessment of trends in performance, particularly in small samples, than does the conventional sole use of low birth weight. Low and suboptimal birth weights are uncommon in Dublin.

Because of conflicting results in previous analyses of possible maternal and paternal effects on the variation in sex ratio at birth, records of United States live births in 1975 were sorted by offspring sex, live birth order (based on maternal parity), parental races, and, unlike prior studies, ungrouped parental ages. Linear regression and logistic analysis showed significant effects of birth order and paternal age on sex ratio in the white race data (1.67 million births; 10,219 different combinations of independent variables). Contrary to previous reported results, the paternal-age effect cannot be ascribed wholly to the high correlation between paternal age and birth order as maternal age, even more highly correlated with birth order, does not account for a significant additional reduction in sex-ratio variation over that accounted for by birth order alone.

Birth Order and Risk of Non-Hodgkin Lymphoma—True Association or Bias?

There is inconsistent evidence that increasing birth order may be associated with risk of non-Hodgkin lymphoma (NHL). The authors examined the association between birth order and related variables and NHL risk in a pooled analysis (1983–2005) of 13,535 cases and 16,427 controls from 18 case-control studies within the International Lymphoma Epidemiology Consortium (InterLymph). Overall, the authors found no significant association between increasing birth order and risk of NHL (P-trend = 0.082) and significant heterogeneity. However, a significant association was present for a number of B- and T-cell NHL subtypes. There was considerable variation in the study-specific risks which was partly explained by study design and participant characteristics. In particular, a significant positive association was present in population-based studies, which had lower response rates in cases and controls, but not in hospital-based studies. A significant positive association was present in higher-socioeconomic-status (SES) participants only. Results were very similar for the related variable of sibship size. The known correlation of high birth order with low SES suggests that selection bias related to SES may be responsible for the association between birth order and NHL.

The causes of childhood cancers are largely unknown. Birth order has been used as a proxy for prenatal and postnatal exposures, such as frequency of infections and in utero hormone exposures. We investigated the association between birth order and childhood cancers in a pooled case-control dataset. The subjects were drawn from population-based registries of cancers and births in California, Minnesota, New York, Texas, and Washington. We included 17,672 cases less than 15 years of age who were diagnosed from1980-2004 and 57,966 randomly selected controls born 1970-2004, excluding children with Down syndrome. We calculated odds ratios and 95% confidence intervals using logistic regression, adjusted for sex, birth year, maternal race, maternal age, multiple birth, gestational age, and birth weight. Overall, we found an inverse relationship between childhood cancer risk and birth order. For children in the fourth or higher birth order category compared to first-born children, the adjusted OR was 0.87 (95% CI: 0.81, 0.93) for all cancers combined. When we examined risks by cancer type, a decreasing risk with increasing birth order was seen in the central nervous system (CNS) tumors, neuroblastoma, bilateral retinoblastoma, Wilms tumor, and rhabdomyosarcoma. We observed increased risks with increasing birth order for acute myeloid leukemia but a slight decrease in risk for acute lymphoid leukemia. These risk estimates were based on a very large sample size which allowed us to examine rare cancer types with greater statistical power than in most previous studies...

Alfred Adler attempted to understand how family affects youth outcomes by considering the order of when a child enters a family (Adler, 1964). Adler’s theory posits that birth order formation impacts individuals. We tested Adler’s birth order theory using data from a cross-sectional survey of 946 Chilean youths. We examined how birth order and gender are associated with drug use and educational outcomes using three different birth order research models including: (1) Expedient Research, (2) Adler’s birth order position, and (3) Family Size theoretical models. Analyses were conducted with structural equation modeling (SEM). We conclude that birth order has an important relationship with substance use outcomes for youth but has differing effects for educational achievement across both birth order status and gender.

The objective of the study is to assess maternal factors contributing to under-five mortality at birth order 1 to 5 in India. Data for this study was derived from the children’s record of the 2007 India National Family Health Survey, which is a nationally representative cross-sectional household survey. Data is segregated according to birth order 1 to 5 to assess mother’s occupation, Mother’s education, child’s gender, Mother’s age, place of residence, wealth index, mother’s anaemia level, prenatal care, assistance at delivery , antenatal care, place of delivery and other maternal factors contributing to under-five mortality. Out of total 51555 births, analysis is restricted to 16567 children of first birth order, 14409 of second birth order, 8318 of third birth order, 5021 of fourth birth order and 3034 of fifth birth order covering 92% of the total births taken place 0–59 months prior to survey. Mother’s average age in years for birth orders 1 to 5 are 23.7, 25.8, 27.4, 29 and 31 years, respectively. Most mothers whose children died are Hindu, with no formal education, severely anaemic and working in the agricultural sector. In multivariate logistic models, maternal education, wealth index and breastfeeding are protective factors across all birth orders. In birth order model 1 and 2...

Birth weight has been inversely associated with later blood pressure. Firstborns tend to have lower birth weight than their later-born peers, but the long-term consequences remain unclear. The study objective was to investigate differences between firstborn and later-born individuals in early growth patterns, body composition, and blood pressure in Brazilian adolescents. The authors studied 453 adolescents aged 13.3 years from the prospective 1993 Pelotas Birth Cohort. Anthropometry, blood pressure, physical activity by accelerometry, and body composition by deuterium were measured. Firstborns (n?? 143) had significantly lower birth weight than later borns (n?? 310). At 4 years, firstborns had significantly greater weight and height, indicating a substantial overshoot in catch-up growth. In adolescence, firstborns had significantly greater height and blood pressure and a lower activity level. The difference in systolic blood pressure could be attributed to variability in early growth and that in diastolic blood pressure to reduced physical activity. The magnitude of increased blood pressure is clinically significant; hence, birth order is an important developmental predictor of cardiovascular risk in this population. Firstborns may be more sensitive to environmental factors that promote catch-up growth...

We use unique retrospective family background data from the 2003 wave of the British Household Panel Survey to explore the degree to which family size and birth order affect a child’s subsequent educational attainment. Theory suggests a trade off between child quantity and ‘quality’. Family size might adversely affect the production of child quality within a family. A number of arguments also suggest that siblings are unlikely to receive equal shares of the resources devoted by parents to their children’s education. We construct a composite birth order index that effectively purges family size from birth order and use this to test if siblings are assigned equal shares in the family’s educational resources. We find that they are not, and that the shares are decreasing with birth order. Controlling for parental education, parental age at birth and family level attributes, we find that children from larger families have lower levels of education, that there is a separate negative birth order effect, and that the family size effect does not vanish once we control for birth order. Our findings are robust to a number of specification checks.; no

Juvenile delinquency has long been associated with birth order in popular culture. While images of the middle child acting out for attention or the rebellious youngest child readily spring to mind, little research has attempted to explain why. Drawing from Adlerian birth order theory and Sulloway's born to rebel hypothesis I examine the relationship between birth order and a variety of delinquent outcomes during adolescence. Following some recent research on birth order and intelligence, I use new methods that allow for the examination of both between-individual and within-family differences to better address the potential spurious relationship. My findings suggest that contrary to popular belief the relationship between birth order and delinquency is spurious. Specifically, I find that birth order effects on delinquency are spurious and largely products of the analytic methods used in previous tests of the relationship. The implications of this finding are discussed.

We used the Swedish Family-Cancer Database to analyse the effects of birth order and family size on the risk of common cancers among offspring born over the period 1958–96. Some 1.38 million offspring up to age 55 years with 50.6 million person-years were included. Poisson regression analysis included age at diagnosis, birth cohort, socio-economic status and region of residence as other explanatory variables. The only significant associations were an increasing risk for breast cancer by birth order and a decreasing risk for melanoma by birth order and, particularly, by family size. When details of the women's own reproductive history were included in analysis, birth orders 5–17 showed a relative risk of 1.41. The effects on breast cancer may be mediated through increasing birth weight by birth order. For melanoma, socio-economic factors may be involved, such as limited affordability of sun tourism in large families. Testis cancer showed no significant effect and prostate cancer was excluded from analysis because of the small number of cases. © 2001 Cancer Research Campaign http://www.bjcancer.com

STUDY OBJECTIVE--The aim was to examine if there is an effect of fathers' age and of birth order on the occurrence of congenital heart disease. DESIGN--This was a hospital based case-referent study including use of birth defects surveillance data. SUBJECTS--Subjects were 497 cases of congenital heart disease aged between 3 months and 5 years, born in Beijing and Hebei Province, China; 6222 children without congenital heart disease serve as reference baseline. MEASUREMENTS AND MAIN RESULTS--With stratified analysis and logistic regression analyses, congenital heart disease was found to be associated with fathers' age less than 25 years (odds ratio 2.63), independent of mothers' age and of birth order. There was also evidence to show a higher birth order effect on the occurrence of congenital heart disease independent of parental ages. CONCLUSION--Higher birth order and fathers aged less than 25 years were both independently associated with some categories of congenital heart disease and with congenital heart disease overall.

As práticas educativas parentais dizem respeito a como os pais monitoram, controlam e socializam seus filhos. Neste artigo, objetiva-se atualizar a literatura na área das práticas educativas parentais considerando-se especialmente dois fatores: o gênero (menino ou menina) e a ordem de nascimento (filho único, primogênito, do meio ou caçula) dos filhos. Foram consultados artigos nacionais e internacionais, sendo esses últimos considerados a partir do ano de 2001. Com relação às práticas educativas parentais e o gênero do filho, observou-se que parece existir uma preferência dos pais com filhos do mesmo sexo que o seu, as mães preferindo as meninas e os pais, os meninos. A literatura também demonstra que há diferenças no modo como meninos e meninas reagem a estressores familiares, sendo que os meninos apresentam maiores níveis de externalização e as meninas, de internalização de comportamento. Os artigos referentes à ordem de nascimento, por sua vez, discutem principalmente como é a alocação de recursos da família de acordo com a posição de nascimento de cada filho. Observou-se que os primogênitos, principalmente do sexo masculino, são os que recebem maior investimento dos pais. A literatura, porém, é frágil e contraditória com relação aos dois aspectos...

Interpersonal style is an aspect of personality related to the particular way individuals participate and gain influence in social contexts. It has its origin in childhood’s first social interactions within the family group. It is suggested that the individual position in the family structure, namely birth order, is an important variable in this process. The present study investigated combined effects of sex and birth order on interpersonal style. A sample of 435 college students (196 men and 239 women) with ranging in age from 18 to 40 years (M = 23,3) answered the BASIS-A (Basic Adlerian Scales of Interpersonal Styles) and a brief demographic questionnaire. Interactions between sex and birth order were found. Lastborn women showed greater tendency to search for success and social approval than firstborn women and lastborn men. Among men, lastborn revealed less need for social approval compared to firstborn and only children. First born men showed a higher need to attend social conventions and obtain success. The interaction between sex and birth order was relevant for the understanding of personality development in the context of family relations.   Keywords: birth order; interpersonal styles; personality.; O estilo interpessoal é um aspecto da personalidade referente à forma particular do indivíduo participar e obter influência no meio social.

Background: Birth order has been suggested to be linked to several cardiovascular disease (CVD) risk factors, but the evidence is still inconsistent. We aim to determine the associations of birth order with body mass index (BMI), muscle strength and blood pressure. Further we will analyse whether these relationships are affected by family characteristics. Methods: BMI, elbow flexion, hand grip and knee extension strength and systolic and diastolic blood pressure were measured at conscription examination in 1 065 710 Swedish young men born between 1951 and 1975. The data were analysed using linear multivariate and fixed effects regression models; the latter compare siblings and account for genetic and social factors shared by brothers. Results: Fixed effect regression analysis showed that birth order was inversely associated with BMI: second and third born had 0.8% and 1.1% (p<0.001) lower BMI than first-born, respectively. The association pattern differed among muscle strengths. After adjustment for BMI, first-born presented lower elbow flexion and hand grip strength than second-born (−5.9 N and −3.8 N, respectively, p<0.001). Knee extension strength was inversely related to birth order though not always significantly. The association between birth order and blood pressure was not significant. Conclusions: Birth order is negatively associated with BMI and knee extension strength...
