We also excluded 50 042 women (5%) with missing information on the following factors related to their first pregnancy: duration of pregnancy, offspring sex, and offspring birth weight.
In contrast to N. californicus, the mating duration of young small P. persimilis males was significantly shorter than that of young standard-sizedmales within the first week, where more than half of all offspring were sired by the P. persimilis males.
The researchers found that neither dose of breast milk nor duration of breastfeeding among offspring of type 1 diabetic women was associated with increased risk of overweight or impaired glucose tolerance at 2 years of age.
D. melanogaster is known to exhibit numerous genetic differences between populations with some life history traits indicative of temperature selection in tropical and temperate populations (body size, duration of development and offspring production) [ 31].
The secondary outcomes are duration of breastfeeding, frequency of offspring dietary intake of sugary beverages, pastry, sweets, fruit, berries, vegetables, type butter or margarine used and frequency of eating takeaway food as well as eating pattern are recorded yearly.
In Table 2, cord blood levels of IGF-1, IGF-2, and IGFBP-3 are compared between cities adjusting for maternal age, height, weight gain, parity, duration of gestation, and gender of offspring.
When all women within each centre were studied, results were adjusted for maternal age, height, parity, weight gain, duration of gestation, and gender of offspring.
The number of egg batches, total number of offspring and the duration of fertile life for females repeatedly exposed to males were not different from that of females exposed to males only once (Table 2).
Multiple mixed effects regression models were used to determine the association between metabolic rate and both number of offspring and gestation duration.
In the present study, we give measures of two aspects of reproductive performance (number of offspring and gestation duration) and report associations between reproductive performance and the SMR of both males and females.
In the present study we used laboratory-bred families (one sire to three dams) of Nauphoeta cinerea (Olivier) (speckled cockroaches) to examine the relationship between standard metabolic rate (SMR) and reproductive performance (number of offspring and gestation duration).
