Apolipoprotein E Polymorphisms in Andean Population of Jujuy, Argentina.

The pleiotropic nature of the apolipoprotein E () gene is associated with complex diseases in different populations. We analyzed polymorphisms in 76 individuals from Jujuy - Argentina using NGS technology. The observed genotypes align with the expected Hardy-Weinberg equilibrium.

Birth weight in the Northwest region of Argentina. Comparison with a national reference and an international standard.

Introduction. Size at birth is subject to genetic and environmental influences; altitude is highly influential. Birth weight (BW) is the most widely used indicator to assess size at birth; different standards and references are available.

Somatotype altitudinal variation and its relationship with the nutritional status of children in the Jujuy province, Argentina.

Objectives: To study the somatotype variations adjusted by altitude, age, sex, and BMI categories, and to assess the health status of the children population.

Methods: A sample of 460 children aged 8-13 years was assessed in a cross-sectional study conducted on anthropometric measurements between 2011 and 2015. Data were categorized into two age groups: Group 8-10, Group 11-13 and two altitudes: Highland (>2000 masl), lowland (<2000 masl).

Spatial distribution and secular trend (1991-2014) of small for gestational age infants born in Jujuy.

Introduction. A fetus that does not reach the expected growth potential in utero is considered small for gestational age (SGA). Such restriction depends on genetic and/or environmental factors, being altitude a very relevant factor.

Human Y chromosome sequences from Q Haplogroup reveal a South American settlement pre-18,000 years ago and a profound genomic impact during the Younger Dryas.

The settlement of the Americas has been the focus of incessant debate for more than 100 years, and open questions regarding the timing and spatial patterns of colonization still remain today. Phylogenetic studies with complete human Y chromosome sequences are used as a highly informative tool to investigate the history of human populations in a given time frame. To study the phylogenetic relationships of Native American lineages and infer the settlement history of the Americas, we analyzed Y chromosome Q Haplogroup, which is a Pan-American haplogroup and represents practically all Native American lineages in Mesoamerica and South America.

Birth Size and Maternal, Social, and Environmental Factors in the Province of Jujuy, Argentina.

Introduction: birth size is affected by diverse maternal, environmental, social, and economic factors.

Aim: analyze the relationships between birth size-shown by the indicators small for gestational age (SGA) and large for gestational age (LGA)-and maternal, social, and environmental factors in the Argentine province of Jujuy, located in the Andean foothills.

Methods: data was obtained from 49,185 mother-newborn pairs recorded in the Jujuy Perinatal Information System (SIP) between 2009 and 2014, including the following: newborn and maternal weight, length/height, and body mass index (BMI); gestational age and maternal age; mother's educational level, nutritional status, marital status and birth interval; planned pregnancy; geographic-linguistic origin of surnames; altitudinal place of birth; and unsatisfied basic needs (UBN).

Continental Origin for Q Haplogroup Patrilineages in Argentina and Paraguay.

Haplogroup Q originated in Eurasia around 30,000 years ago. It is present in Y-chromosomes from Asia and Europe at rather low frequencies. Since America is undoubtedly one of the continents where this haplogroup is highly represented, it has been defined as one of the founding haplogroups.

Newborn anthropometry, maternal capital, and altitude in the highland population from the province of Jujuy, Argentina.

Objective: To analyze variability in newborn (NB) anthropometry among Jujenean NBs as a function of geographic altitude (500 m to ≈4000 masl), maternal anthropometry and other maternal characteristics within the maternal capital framework.

Materials And Methods: Data obtained from 41,371 mother/child pairs recorded in the Jujuy Perinatal Information System (SIP) between 2009 and 2014, including: NB and maternal weight, length/height and BMI; gestational age (corrected); maternal age, educational level, nutritional status, and marital status; birth interval; and planned pregnancy. Based on the declared place of residence, the prevalence of unsatisfied basic needs (% UBN) was determined and the data was split into two altitudinal groups: highlands (HL, >2500 masl) and lowlands (LL, <2500 masl).
