“…In line with this idea, primogeniture (first offspring inheritance) is widespread in human populations [for a review, see 38], and firstborns tend to end up in an advantaged position during upbringing with regard to both health [29], [62] and educational achievement [34], [63]. In accordance with this, our results showed that firstborn sons were those who gave birth to the largest numbers of offspring, and this is presumably because they began reproduction earlier.…”

Middleborns Disadvantaged? Testing Birth-Order Effects on Fitness in Pre-Industrial Finns

Parental investment is a limited resource for which offspring compete in order to increase their own survival and reproductive success. However, parents might be selected to influence the outcome of sibling competition through differential investment. While evidence for this is widespread in egg-laying species, whether or not this may also be the case in viviparous species is more difficult to determine. We use pre-industrial Finns as our model system and an equal investment model as our null hypothesis, which predicts that (all else being equal) middleborns should be disadvantaged through competition. We found no overall evidence to suggest that middleborns in a family are disadvantaged in terms of their survival, age at first reproduction or lifetime reproductive success. However, when considering birth-order only among same-sexed siblings, first-, middle- and lastborn sons significantly differed in the number of offspring they were able to rear to adulthood, although there was no similar effect among females. Middleborn sons appeared to produce significantly less offspring than first- or lastborn sons, but they did not significantly differ from lastborn sons in the number of offspring reared to adulthood. Our results thus show that taking sex differences into account is important when modelling birth-order effects. We found clear evidence of firstborn sons being advantaged over other sons in the family, and over firstborn daughters. Therefore, our results suggest that parents invest differentially in their offspring in order to both preferentially favour particular offspring or reduce offspring inequalities arising from sibling competition.

“…Unless further factors such as the spacing or the gender of siblings (Elliott, 1992) impact strongly on the dependent variable, our observations indicate that birth order is not positively correlated with risk perception. Assuming that behavioral differences between siblings are genuine, independent traits, for example, competitiveness, may come into play (Carette et al, 2011).…”

Risk attitudes and birth order

Risk attitudes play important roles in health behavior and everyday decision making. It is unclear, however, whether these attitudes can be predicted from birth order. We investigated 200 mostly male volunteers from two distinct settings. After correcting for multiple comparisons, for the number of siblings and for confounding by gender, ordinal position predicted perception of health-related risks among participants in extreme sports (p < .01). However, the direction of the effect contradicted Adlerian theory. Except for alcohol consumption, these findings extended to self-reported risk behavior. Together, the data call for a cautious stand on the impact of birth order on risk attitudes.

Backgound: A number of studies have documented relationship between various individual outcomes and birth order. This study sought to investigate the relationship between adolescents health behavior, stress and birth order. Methods: The data used in this study were obtained middle and high school students who replied to the 10th Korea Youth Risk Behavior Web-based Survey (KYRBWS) administered in 2014. We investigated the associations between health behavior, stress and birth order using multivariable logistic regression analysis controlling with age, height, weight, father's education, mother's education, economic status, academic status, sleep duration, sitting time, self-perceived health status, self-perceived happiness, depression mood, suicide idea, suicide plan, suicide attempt, drinking experience, smoking experience. Results: The distribution of first-born was 45.5% and later-born was 54.5%. In multivariable logistic regression the later-born replied higher portion of vigorous physical activity 3 days per week and strength exercise 5 days per week. And later-born replied lower economic status, lower academic performance and higher prevalence of drinking experience, smoking experience. Later-born they had more stress than first-born, but after adjusted for variable factors in multivariable logistic regression, birth order had no relationship with stress significantly. Conclusions: This study offers data for the development of intervention programs to adolescent related to birth order, and further study is necessary in order to clarify adolescent's relationship between birth order and stress and individual outcomes.
