Anthropometric assessment of nutritional status in pregnant women: a reference table of weight-for-height by week of pregnancy

Abstract

A reference table of weight-for-height by week of pregnancy has been devised on theoretical grounds, based on the premises that the average increment of weight during pregnancy is 20% of the prepregnant weight and that almost all the increment takes place linearly during the 2nd and 3rd trimesters of pregnancy. The table was tested with retrospective clinic and hospital data. The results show a good correlation between the weight-for-height at different stages of pregnancy as a percentage of the reference table and the birth weight of the offsprings. This reference table can be a useful tool to assess the nutritional status of pregnant women and, within limits, to "predict" the chances of delivering a low birth weight infant.

Microbiota at Multiple Body Sites during Pregnancy in a Rural Tanzanian Population and Effects of Moringa-Supplemented Probiotic Yogurt

“…Likewise, periodontal disease with poor oral hygiene has been linked with preterm labor (37), but the Tanzanian women studied here did not present with acute periodontal disease as identified during The percent deviation was calculated based on the participant's gestational age (calculated from participant recall of the last menstrual period) and height as measured at baseline. These were used to determine the ideal weight of the participants as outlined by Gueri et al (25). The weight of the participants measured at baseline was then used to calculate the percent deviation from the ideal weight.…”

“…To confirm, or if last menstrual period was unavailable, approximation of gestational age was based upon measurement of fundal height. Originally, participants were further grouped into states of nutritional status (nourished or undernourished) based upon having a mid-upper-arm circumference (MUAC) of Ͻ235 mm if undernourished, and deviations from expected weight for gestational age (25). Since this was a pilot study, sample size was based on participant availability.…”

Relationship between maternal nutritional status and infant’s weight and body proportions at birth

“…The retrospective nature of the study did not allow us to obtain prepregnancy weights, so mother's weight at 8±10 weeks postconception was used as a proxy for her prepregnancy weight. Gueri et al (1982), have suggested that there is an increase of only 1.7% over the prepregnant weight during the ®rst 13 weeks of pregnancy. In this group of mothers, 13% had a BMI 19, suggesting that they entered pregnancy on a lower nutritional plane, and we have shown previously that mothers with thinner triceps skinfolds had children who at age 11 y had higher blood pressures (Godfrey et al, 1994).…”

Exactitud diagnóstica de cinco referencias gestacionales para predecir el peso insuficiente al nacer

“…Desde la década de los 40, se han elaborado múltiples gráficas para evaluar el estado nutricional de la embarazada en el continente americano. Las más conocidas en Estados Unidos son la de Chesley, 1944; la de Tompkins y Wiehl, 1951; la de Hytten y Leitch, 1971 (19); la de Gueri y col., 1982 (19,20); la de Rosso P., 1985 (19,21); la de Brown y col., 1986 (19); la de Husaini, 1986 (19); la de Dimperio, 1988 (19), y la del Instituto de Medicina de Estados Unidos, 1990 (2,22,23).…”
