“…Some studies have reported that some adverse perinatal outcomes were associated with maternal short stature, including low birth weight and neonatal asphyxia [15][16][17][18]. These findings were not confirmed in this study.…”

Objectives: To evaluate the relationship between maternal height of <155 cm and the risk of caesarean delivery due to failure to progress (FTP) among nulliparous saudi women. Design: Observational cohort study. Material and Method: A total of 405 term (GA > 37 weeks), uncomplicated singleton nulliparous pregnant women were enrolled on admission to labour room. The patients were divided into two groups based on maternal height, >155 cm (247 cases) as control and < 155 cm (158 cases) as study group. The medical records of these women were reviewed. Various baseline clinical characteristics were collected. Maternal characteristics and maternal and neonatal outcomes were recorded. Results: Caesarean section rate for all indications was higher among study group than control group (26.6% and 19.4% respectively, p = 0.023). Significant difference was observed in the rate of caesarean delivery due to failure to progress (7.3% and 12% in control and study group respectively, p-value 0.038). The rate of caesarean delivery due to failure to progress was highest among those with height 150 -155 cm (p-value 0.022). Mean birth weight was significantly higher among control group than study group (3137 ± 403 g and 3030 ± 408 respectively, p-value 0.010). Conclusion: Term singleton nulliparous Saudi pregnant women with maternal height 151 -154 cm were associated with a greater likelihood of caesarean section for failure to progress. Women with height <150 cm did not have increased cesarean section rate. However, mean birth weight was significantly lower in this group.

“…Thus, the girls may start pregnancy at a great disadvantage. Moreover, they are at increased risk of problems in delivery due to cephalopelvic disproportion and of delivering low birth weight infants (26,27,28). So, programs to support adequate nutrition for adolescents could provide an opportunity for healthy transition from childhood to adulthood and could be an important step towards breaking the vicious cycle of intergenerational malnutrition.…”

Background: Addressing the nutritional needs of adolescents could be an important step towards breaking the vicious cycle of intergenerational malnutrition. Objective: Assess nutritional status of rural adolescent girls. Design: Cross-sectional. Methods: Anthropometric and socio-demographic information from 211 adolescent girls representing 650 randomly selected households from thirteen communities in Tigray was used in data analysis. Height-for-age and BMI-for-age were compared to the 2007 WHO growth reference. Data were analyzed using SAS, Version 9.1. Results: None of the households reported access to adolescent micronutrient supplementation. The girls were shorter and thinner than the 2007 WHO reference population. The cross-sectional prevalence of stunting and thinness were 26.5% and 58.3%, respectively. Lack of latrine facilities was significantly associated with stunting (p = 0.0033) and thinness (p<0.0001). Age was strong predictor of stunting (r 2 = 0.8838, p<0.0001) and thinness (r 2 = 0.3324, p<0.0001). Conclusion: Undernutrition was prevalent among the girls. Strategies to improve the nutritional status of girls need to go beyond the conventional maternal and child health care programs to reach girls before conception to break the intergenerational cycle of malnutrition. Further, carefully designed longitudinal studies are needed to identify the reasons for poor growth throughout the period of adolescence in this population. IntroductionAdolescence is an intense anabolic period when requirements for all nutrients increase. During adolescence, 20% of final adult height and 50% of adult weight are attained, bone mass increases of 45% and dramatic bone remodeling occur and soft tissues, organs, and even red blood cell mass increase in size (1). This situation is further complicated when adolescents are often exposed to infections and parasites that can compromise nutritional status. Among those sexually active, there is also an increased risk of infection from sexually transmitted diseases.

“…2). The risk of cephalopelvic disproportion-and hence the strength of obstetric selection-is associated with the mother's stature (25)(26)(27)(28)(29)(30) and the newborn's head size, which in turn is genetically correlated with the head size of the mother (23). The optimal compromise solution for pelvis shape may thus not be uniform within a population but may rather depend on stature and head size.…”

“…A short woman with a small pelvis might give birth to a large neonate with a large head, inherited from a much taller father. As this suggests, shorter women, on average, have harder births than taller women (25)(26)(27)(28)(29)(30).…”

Compared with other primates, childbirth is remarkably difficult in humans because the head of a human neonate is large relative to the birth-relevant dimensions of the maternal pelvis. It seems puzzling that females have not evolved wider pelvises despite the high maternal mortality and morbidity risk connected to childbirth. Despite this seeming lack of change in average pelvic morphology, we show that humans have evolved a complex link between pelvis shape, stature, and head circumference that was not recognized before. The identified covariance patterns contribute to ameliorate the "obstetric dilemma." Females with a large head, who are likely to give birth to neonates with a large head, possess birth canals that are shaped to better accommodate large-headed neonates. Short females with an increased risk of cephalopelvic mismatch possess a rounder inlet, which is beneficial for obstetrics. We suggest that these covariances have evolved by the strong correlational selection resulting from childbirth. Although males are not subject to obstetric selection, they also show part of these association patterns, indicating a genetic-developmental origin of integration.
