WEIGHT. A quality in natural bodies, by which they tend towards the centre of the earth.
     2. Under the article Measure, (q.v.) it is said that by the constitution congress possesses the power "to fix the standard of weights and measures," and that this power has not been exercised.
     3. The weights now generally used in the United States, are the same as those of England; they are of two kinds:

     1. AVOIRDUPOIS WEIGHT. 1st. Used in almost all commercial transactions, and in the common dealings of life. 27 1/3 1/2 grains = 1 dram 16 drams = 1 ounce 16 ounces = 1 pound, (lb.) 28 pounds = 1 quarter, (qr.) 4 quarters = 1 hundred weight, (cwt.) 20 hundred weight = 1 ton. 2d. Used for meat and fish. 8 pounds = 1 stone 3d. Used in the wool trade.
     Cwt. qr. lb. 7 pounds = 1 clove 14 pounds = 1 stone = 0 0 14 2 stones = 1 tod = 0 1 0 6 1/2 tods = 1 wey = 1 2 14 2 weys = 1 sack = 3 1 0 12 sacks = 1 last = 39 0 0 4th. Used for butter and cheese. 8 pounds = 1 clove 56 pounds = 1 firkin.
     2. TROY WEIGHT. 24 grams = 1 pennyweight 20 pennyweights = 1 ounce 12 ounces = 1 pound.

     4. These are the denominations of troy weight, when used for weighing gold, silver and precious stones, except diamonds. Troy weight is also used by apothecaries in compounding medicines; and by them the ounce is divided into eight drams, and the drain into three scruples, so that the latter is equal to twenty grains. For scientific purposes, the grain only is used, and sets of weights are constructed in decimal progression, from 10,000 grains downward to one-hundredth of a grain. The caret, used for weighing diamonds, is three and one-sixth grains.
     5. A short account of the French weights and measures is given under the article Measure.

Fourth, there is some evidence for supplementation of very low birth weight infants with vitamin A, vitamin D, calcium and phosphorus starting as soon as feeding is established, and for all low birth weight infants with iron starting after 8 wk of age.
Univariate logistic regression analysis for stillbirths and low and very low birth weight confirmed a trend of increasing prevalence with higher TTHM concentrations in United Utilities but not in the other regions.
Those who had a history of very low birth weight had twice the risk of being hospitalized for asthma or respiratory infection and 2.6 times the risk of respiratory failure requiring mechanical ventilation.
Six birth outcomes were studied: low birth weight (less than 2,500 g), very low birth weight (less than 1,500 g), preterm birth (20-36 weeks' gestation), very preterm birth (20-31 weeks' gestation), fetal death at 20 or more weeks and neonatal death (before hospital discharge or, for infants delivered in a non-hospital setting, before completion of the birth certificate).
Then two separate multiple logistic models were fitted for two outcomes: low birth weight and very low birth weight. Low birth weight was defined as infants weighing between 1,500 and 2,500 g at birth, and very low birth weight was defined as infants weighing < 1,500 g.
Thus, Vivette D'Agati, MD, of the Columbia University College of Physicians and Surgeons in New York City, NY, and her colleagues studied six patients (two women and four men) who had clinical indications of this condition and who were born prematurely and of a very low birth weight.
The birth outcomes assessed were low birth weight (less than 2,500 g); very low birth weight (less than 1,500 g); preterm birth (before 37 weeks' gestation); intrauterine growth retardation (birth weight less than the third percentile); and fetal and infant mortality.
(1) Among infants born there in 1995, those whose mothers had a diagnosed psychiatric or substance-related disorder had roughly 2-4 times the odds of other babies of having a low or very low birth weight, and of being delivered preterm.
Among women receiving combination therapy, however, users of protease inhibitors may be more likely than nonusers to have a very low birth weight infant (odds ratio, 3.6).
Infants conceived with the use of assisted reproductive technology (ART) are more likely than infants in the general population to have low or very low birth weight, a large population-based study reveals.
Although previous studies have shown only that very-low-birth-weight individuals encounter educational disadvantage during youth, the researchers suggest that "this disadvantage extends into young adulthood." They also conclude that it is likely that "men who had very low birth weight will lag behind their normal-birth-weight peers in their ultimate educational and occupational achievement." That very low birth weight was significantly associated with lower rates of risk-taking behavior was not one of the researchers' starting hypotheses.
Infant deaths increased to 27,970 in 2002, compared with 27,568 the year before, mainly because of a rise in the number of babies born at very low birth weights, the Centers for Disease Control and Prevention reported.
