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 ...

We investigated whether blood pressures are higher in normotensive offspring of hypertensive parents than in normotensive offspring of normotensive parents outside the physician's office and, if so, whether these higher blood pressures are dependent on the level of dietary sodium intake. We compared 24-hour ambulatory blood pressure profiles between 11 normotensive sons of two hypertensive pare...

BACKGROUND Natural selection should favour the ability of mothers to adjust the sex ratio of offspring in relation to the offspring's potential reproductive success. In polygynous species, mothers in good condition would be advantaged by giving birth to more sons. While studies on mammals in general provide support for the hypothesis, studies on humans provide particularly inconsistent results,...

According to Robey, Cohen, and Epstein (1988), children may hold a naïve theory of affection, whereby they believe that their parents’ affection for them is a finite resource for which they must compete against their siblings. Parents, conversely, are unlikely to view their own affection in the same way. Although research on naïve theories is often conducted with youngsters, we speculated that ...

The changes of cancer incidence upon immigration have been used as an estimator of environmental influence on cancer risk. The previous immigrant studies have indicated that the origins of testicular cancer are at an early age in life, probably in the intrauterine period. We wanted to reexamine the critical periods on histology-specific testicular cancer in sons of immigrants to Sweden. We used...

Abstract Although the literature on informal care-giving for older parents shows that daughters have a higher tendency to provide care compared with sons, only few studies focused gender composition of all children or parents’ entire range options. Our study examines effect children's and formal types, as well network. Using data from 2015 Survey Health, Ageing Retirement in Europe (N = 40,312)...
