Fetal viability is the ability of a human fetus to survive outside the uterus. Viability depends upon factors such as birth weight, gestational age, and the availability of advanced medical care. In low-income countries, more than 90% of extremely preterm newborns (less than 28 weeks gestational age) die due to a lack of said medical care; in ...
Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2] On average, babies of Asian descent weigh about 3.25 kilograms (7.2 lb).
SGA is not a synonym of low birth weight, very low birth weight, or extremely low birth weight. For example, with a 35-week gestational age delivery, 2250 g weight is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates – infants weighing less than 2500 g – are small for gestational age.
List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous ( marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
Frequency. 213 million (2012) [11] Deaths. 230,600 (2016) [12] Pregnancy is the time during which one or more offspring develops ( gestates) inside a woman 's uterus (womb). [4] [13] A multiple pregnancy involves more than one offspring, such as with twins. [14]
Researchers observed that the liver weight is directly proportional to the body weight. At 8–12 weeks of gestation, liver is a relatively bigger organ which forms 4-5-5.5% of the total body weight and protrudes through the abdominal wall. By 13 to 32 weeks of gestation, it forms 3.4% to 4.0% of the total body weight.
Nutrition and pregnancy refers to the nutrient intake, and dietary planning that is undertaken before, during and after pregnancy. Nutrition of the fetus begins at conception. For this reason, the nutrition of the mother is important from before conception (probably several months before) as well as throughout pregnancy and breastfeeding.
The study found that over a nine month period, 77.9% of participants reported a decrease in body weight while using Noom — and the prevalence of obesity was cut by 30%. That is seriously ...
