Pathogenesis and Prognosis of Prematurity

Effect of Periodontal Therapy on Pregnancy Outcome in Women Affected by Periodontitis

“…Because all subjects included in the study were housewives, the socioeconomic status was classified according to the husband's occupation 3 as follows: class I (professionals), class II (intermediate), class III (skilled worker), class IV (partly skilled worker), and class V (unskilled worker). Information about alcohol consumption, tobacco use (smoking/non‐smoking), and pan chewing was obtained through personal interview.…”

“…Various factors have been associated with the delivery of preterm and/or low birth weight (LBW) infants. Maternal risk factors include age, height, weight, socioeconomic status, ethnicity, smoking, alcohol consumption, nutritional status, and stress 3,4 . In addition, parity, birth interval, previous complications, pre‐ and antenatal care, maternal hypertension, infections, and cervical incompetence also may be important 5,6 …”

The Influence of Socioeconomic Status on Incidence of Low Birth Weight

“…The source of antenatal care is yet another variable that has been related to the incidence of immaturity (16). Women who receive care from a private physician may obtain services of a different quality from those provided through public sources.…”

MMPI correlates of Negro acculturation in a northern city.

“…The sample used in the present study is a subsample (N = 326) of the sample (N = 772) of lowerclass pregnant women attending the Prenatal Clinic at the Boston City Hospital and described by Harrison and Kass (1967). On the basis of evidence linking bacterium and low plasma volume to prematurity (Abramowicz & Kass, 1966), 226 subjects with augmented risk of prematurity and 226 matched controls were selected from the original study population of 1,036 for a psychiatric interview. The criterion for selection was either evidence of bacteriuria in two successive urine specimens (Savage, Hajj, & Kass, 1967) or a plasma volume below 2,900 cubic centimeters.…”
