Results from the adjusted generalized additive models supported linear dose-response relationships between maternal urinary arsenic concentrations and gestational age, head circumference, birth length, birth weight, ponderal index, birth length percentile, and birth weight percentile (data not shown).
However, all studied variants were not independently associated with birth length and ponderal index (data not shown).
Weight, length, ponderal index and intrauterine growth retardation in Brazil.
Indirect measures of relative adiposity or fatness include waist, hip and other girth measurements, skinfold thickness, bioelectrical impedance analysis (BIA), and indices derived from measured height and weight such as body mass index (BMI), the ponderal index (weight/[height.
Thus, the children of smokers tended to be shorter and have a higher ponderal index than children of nonsmokers.
The presence of antenatal corticosteroid administration, gender, gestational age, birth weight, height, ponderal index, length, mode delivery, Apgar scores and mode of delivery were recorded for each infant.
Outcomes of interest included newborn birth weight, birth weight z score, Ponderal Index, and large for gestational age (LGA; defined as greater than the 90th percentile).
The ponderal index at birth was calculated with the standard formula of weight (kg) divided by the cube of the length at birth ([m.
Stopping smoking before 32 weeks' gestation may prevent the adverse effects on birth weight and head circumference but has not been shown to prevent decreased height or increased ponderal index (a shorter and/or fatter infant).
The ponderal index (weight/length (3)) and head-to-length ratio were calculated as indices of disproportionality at birth (23,25).
Shea and his associates did find, as expected, that both body mass index and ponderal index were associated with fasting insulin level and with insulin resistance, which correlated very highly with fasting insulin.
