“…High altitude has also been shown to adversely influence birth outcome . For instance, newborns at higher altitudes in Argentina were more likely to born preterm and at low birthweight than those born at lower altitudes . In addition, Han Chinese women who immigrated to Tibet were more likely to give birth to low‐birthweight newborns than women originally from Tibet , suggesting some physiological adaptation across generations .…”

Aim: Adverse birth outcomes are a major public health issue in rural areas, where several environmental risk factors, including pesticides, may endanger the health of women of reproductive age. We investigated the prevalence of selected birth outcomes among newborns from mothers living in urban and rural areas of a Brazilian municipality.Methods: Information about all live births that occurred between 2004 and 2006 in the Municipality of Nova Friburgo, Brazil, was retrieved from the Live Birth Information System. Newborns were classified as rural or urban, according to the mother's residence address. Results: Newborns from rural areas had a higher prevalence of very low-birthweight, low Apgar score, and malformation. On Poisson regression with adjustment for several confounders, rural offspring were more likely to have the aforementioned outcomes. Conclusions: Women in rural areas are at higher risk of giving birth to an infant with very low-birthweight, low 5-min Apgar score and malformations detectable at birth, regardless of socioeconomic and gestational conditions.

“…In the province of Jujuy, and using the same source, Grandi et al 30 have demonstrated that the prevalence of prematurity, small for gestational age infants, and mild and severe intrauterine growth restriction are increasingly related to high-altitude; the latter two factors are even, significantly, twice as high in the Puna than in Maternidad Sardá, a maternity center located at sea level. Candelas et al 31 reach the same conclusion when analyzing birth weight in the province of Catamarca, and they establish that the increased incidence of preterm births caused by a higher altitude above sea level may account for an adaptive advantage of preterm delivery in these conditions. Finally, other cultural and physiological factors, which are related to one another, may account for the higher infant mortality observed in high-altitude environments.…”

“…Mothers who lived in the highlands with lower oxygen level risked her baby for hypoxic fetal syndrome that causes neonatal asphyxia and LBW [62]. Differences were found in birth weight based on sexes and in the incidence of low birth weight depending on altitude [63], while the findings Tibetan birth weights are greater than those of other ethnic groups, both at high and low altitudes. Tibetans at low altitudes have heavier birth weights compared with Tibetans at high altitude.…”

<span lang="EN-US">Low birth weight (LBW) is a significant public health problem in the world. It was estimated globally by the World Health Organization (WHO) that prevalence of LBW was 15% of all births. In Murung Raya district LBW cases remain high. This paper aimed to identify and discuss the relationship between environmental risk factors with LBW in Murung Raya.A spatial analysis was conducted with 150 women as the total participantswho were recruited through the incidence data in 2013-2014. The questionnaires, medical records, and geographic data were measured by Stata software, ArcGis, SatScan, and Geoda. The study results indicated there was significant correlation between health behavior and environmental variables with the strength of external neighborhood effect across LBW risk factors. </span><span lang="EN-US">More intense clustering of high values (hot spots) was found through the spatial analysis showing that most of the cases were located near the defined buffer zone. This research demonstrates that the spatial pattern analysis provided greater statistical power to detect an effect that was not apparent in the previous epidemiology studies.</span>

Altitude effect on birth weight and prematurity in the Province of Catamarca (Argentina)

Abstract: To be female appears to be a benefit under conditions of prematurity and high altitude. The increased incidence of prematurity due to altitude increase may reflect an adaptive advantage of preterm birth under these conditions.
