Pregnancy length: Secular trends and patterns of variation in Sweden, 1982-2005 Anthropological and medical studies rarely investigate the existence of secular trends in the duration of human pregnancy, which is widely assumed to show less variation than traits such as body size, menarche or lifespan. Here we analyze pregnancy duration in the Swedish population between 1982 and 2005, and correlation patterns of four variables: pregnancy length, maternal height, newborn weight and newborn head circumference. Results reveal positive trends of very small magnitude in the four traits. Although bivariate correlations were all significant and positive, multiple linear regression shows a positive independent contribution of newborn size (both weight and head circumference) and a negative independent contribution of maternal height to pregnancy length. We propose that the very weak and negative independent contribution of maternal height to pregnancy duration, in contrast to the stronger and positive contribution of newborn size, explain the absence of significant secular trends in pregnancy duration in Sweden. The results confirm some of the predictions of the maternal investment hypothesis, the ‘obstetrical dilemma’, and Ellison's metabolic crossover hypothesis. Due to the weak association between pregnancy length and maternal height, we hypothesize that pregnancy length is expected to show limited secular change even in a population undergoing strong secular trends in maternal height.

Abstract Background Children with hypochondroplasia (HCH), who have FGFR3 mutations c.1620C>A or c.1620C>G (p.Asn540Lys) appear to have a more severe phenotype than those with HCH without these mutations. We describe the change in height, leg length and body proportions in a retrospective cohort of children with HCH related-p.Asn540Lys mutation and we compared them with Argentine population. Methods Anthropometric measurements were initially taken and followed up by the same observer, with standardized techniques. Sitting height/height and head circumference/height ratio were calculated as a body disproportion indicator. In order to make a comparison with the Argentine population height average, centiles of height, leg length and body proportions were estimated by the LMS method. Results The sample consisted of 57 HCH children (29 males and 28 females) between the ages of 0–18 years. The median (interquartile range) number of measurements per child was 8 (4.3, 13) for height, 7 (4, 12) for sitting height and 7.5 (4, 12.8) for head circumference. Leg length increased from 17 cm at birth to approximately 54 cm in adolescents, 25 cm shorter than the leg length in non-HCH populations. Sitting height increased from 39 cm at birth to 81 cm in adolescents, 7 cm below mean in non-HCH adolescents. Mean (range) adult height were 143.6 cm (131–154.5) and 130.8 cm (124–138) for males and females, respectively. Conclusions The disharmonic growth between the less affected trunk and the severely affected limbs determine body disproportion in HCH.

In rodents and humans there is a sexually dimorphic pattern of GH secretion that influences the serum concentration of IGF-I. Pattern differences can be identified in children, but it is not known how early this difference is established. We studied the plasma concentrations of IGF-I, IGF-II, IGF-binding protein-3 (BP-3), and GH in cord blood taken from the offspring of 1650 singleton Caucasian pregnancies born at term and related these values to birth weight, length, and head circumference. Pregnancies complicated by preterm delivery, antepartum hemorrhage, pregnancy-induced hypertension, preeclampsia, or gestational diabetes and where cigarette smoking continued were excluded, resulting in a cohort of 987. Cord plasma concentrations of IGF-I, IGF-II, and IGFBP-3 were influenced by factors influencing birth size: gestational age at delivery, mode of delivery, maternal height, and parity of the mother. Plasma GH concentrations were inversely related to the plasma concentrations of IGF-I and IGFBP-3; 10.2% of the variability in cord plasma IGF-I concentration and 2.7% for IGFBP-3 was explained by sex of the offspring and parity. None of the factors, apart from maternal height, influenced cord serum IGF-II concentrations (adjusted r2 = 1%). Sex of the baby, mode of delivery, and parity influenced cord serum GH concentrations (adjusted r2 = 2.6%). Birth weight, length, and head circumference measurements were greater in males than females (P < 0.001). Mean cord plasma concentrations of IGF-I (males, 66.4 ± 1.2 μg/liter; females, 74.5 ± 1.3 μg/liter; P < 0.001) and IGFBP-3 (males, 910 ± 13 μg/liter; females 978 ± 13 μg/liter; P < 0.001) were significantly lower in males than females. Cord plasma GH concentrations were higher in males than females (males, 30.0 ± 1.2 mU/liter; females, 26.9 ± 1.1 mU/liter; P = 0.05), but no difference was noted between the sexes for IGF-II (males, 508 ± 6 μg/liter; females, 519 ± 6 μg/liter; P = NS). After adjustment for gestational age, parity, and maternal height, cord plasma concentrations of IGF-I and IGFBP-3 along with sex explained 38.0% of the variability in birth weight, 25.0% in birth length, and 22.7% in head circumference. These data demonstrate that in a group of singleton Caucasian babies born at term, cord plasma IGF-I, IGFBP-3, and GH concentrations relate to birth size, with evidence for sexual dimorphism in the GH-IGF axis.

INTRODUCTION: Newborn health is closely related to that of their mothers. The simple indicators of the mother like haemoglobin level, height, weight, gestational age of the mother will give the first hand information of deviated health of the neonates. MATERIAL AND METHODS: Descriptive correlation study was conducted to assess the impact of physical health status of antenatal mothers on their neonates, 170 antenatal mothers and their born neonates were selected by using purposive sampling. Semi-structured interview schedule, observation of record review and measurement of physical health parameters were used for data collection.  A descriptive and inferential statistics were used to investigate the relationships between the variables of antenatal mothers with their neonates with SPSS software version 16. RESULTS: The study findings revealed that the weight of the neonates has statistically significant correlation with the maternal weight, height, hemoglobin and maternal gestational weeks; length of the neonates has statistically significant correlation with the maternal height, maternal weight and maternal age; Gestational age (Ballard score) with the maternal gestational weeks and neonates birth weight; neonates head circumference has statistically significant with the maternal height, gestational weeks and maternal weight; chest circumference of the neonates has statistically significant with the maternal height and maternal weight. CONCLUSION: The study concluded that there was a significant correlation between the selected maternal weight, height, hemoglobin and gestational weeks with neonatal weight; maternal height, weight, age with neonatal length, head circumference, chest circumference and maternal gestational weeks with neonate gestation age by Ballard score.

AbstractObjectivesMeasurement of birth length and birth head circumference is part of the newborn assessment. Both measurements aid in distinguishing between proportionate and disproportionate small and large for gestational age newborns. It had been shown that birth weight is related to maternal height and weight. This study aims to analyze birth length and birth head circumference percentiles based on maternal stature.MethodsThis observational study analyzed birth length and birth head circumference percentiles of 2.3 million newborns stratified by maternal height and weight from the first obstetric assessment. Percentiles were calculated for sex and 22–43 gestational weeks for all infants. Eighteen subgroups based on six maternal height and three weight strata were defined and percentiles calculated from 32 to 42 gestational weeks using GAMLSS package for R.ResultsNewborns of mothers with height <158 cm and weight <53 kg (short stature) had a rate of preterm birth of 9%, compared to 5% in the tall stature group (height >177 cm, weight >79 kg). Small stature mothers were 1.7 years younger. Birth length differed by several centimeters for the same percentiles between groups of short and tall stature mothers, whereas birth head circumference differed up to 1.2 cm. The largest deviation of birth length was between the 97th percentiles. For male newborns born at term, birth length at the 97th percentile differed by 3.2 cm, at the 50th percentile by 2.7 cm and at the third percentile by 2.5 cm.ConclusionsBirth length and birth head circumference are related to maternal height and weight. To more completely assess newborns, the maternal size should be considered.

Abstract. This study examined the effect of some maternal factors on the pre- and postnatal development of a group of infants of diabetic mothers (IDMs). Body weight, length and head circumference were measured at birth and at 3, 6, 12, 24, 36, and 48 months of age. No differences were observed in pre- and postterm growth when IDMs were subdivided according to the maternal White class or pregnancy complications. Poor metabolic control during pregnancy resulted in excessive and abnormal prenatal growth; the fetal weight increased progressively during the last 3 weeks of gestation, while little or no increase was observed in fetal length or the head circumference which at 37 weeks both were already higher than (length) or similar to (head circumference) those of normal babies at term. Children of mothers with poor metabolic control during pregnancy showed significantly higher values for weight and weight/height ratio in infancy than children of well controlled mothers. Female offspring contributed most to the differences.
