| Summary: | The primary objective of the National Pregnancy and Health
Survey (NPHS) was to produce national annual estimates of the
percentages and numbers of mothers of live newborns in the United
States who used selected licit and illicit drugs in the 12 months
prior to delivery. A further objective was to describe patterns of
prenatal substance use among demographic subgroups of
women. Information on demographic and socioeconomic characteristics,
obstetric history, and drug treatment of women who delivered infants
at sampled hospitals was obtained through an interviewer-administered
questionnaire, while data on substance use before and during pregnancy
were collected through a questionnaire completed by the respondent and
concealed from the interviewer. Respondents were asked about use of
the following substances: alcohol, amphetamines, analgesics, cocaine,
crack cocaine, barbiturates, hallucinogens, hashish, heroin,
marijuana, methadone, methamphetamine, sedatives, stimulants, tobacco,
and tranquilizers. Additionally, information was collected on the
respondent's pregnancy, prenatal care, delivery, previous pregnancies,
and background. Additional data were obtained from the mothers' and
infants' medical records. Urine specimens collected routinely by the
hospital on obstetric admissions were tested for selected
drugs. Finally, in a subsample of six hospitals, hair specimens were
requested from respondents to evaluate the potential of hair as a
source of toxicological data in future studies. |

| Sample: | A two-staged sampling procedure within strata was used,
with selection of hospitals in the first stage and selection of
mothers within the sampled hospitals in the second stage. The sampling
frame for hospitals included all hospitals in the contiguous United
States with 200 or more births per year. Hospitals were stratified by
(1) metropolitan area hospitals in counties with high concentrations
of Hispanics, (2) other metropolitan hospitals, and (3)
nonmetropolitan hospitals. Hospitals were selected with probability
proportionate to size using the number of births in 1989 as a measure
of size. The final sample consisted of 37 hospital clusters containing
60 individual hospitals. The response rate among the 60 hospitals
originally sampled was 65 percent (39 hospitals). Of the 21 hospitals
that refused participation, 13 were replaced following specific
substitution rules. Eight hospitals refused participation and were not
replaced, for a final sample of 52 hospitals. Mothers were randomly
selected from within the participating hospitals. Of the 3,386 mothers
sampled for the survey, percent (46) were found to be ineligible.
These were women who spoke neither English nor Spanish. Of the 3,340
eligible mothers, 89 percent (3,007) could be approached (i.e., the
hospital allowed them to be contacted). Of all eligible respondents,
2,613 completed the questionnaire on substance use. This was 78
percent of the those eligible and 87 percent of those
approached. Mothers' and infants' medical records were abstracted for
92 percent of the women who completed the substance use
questionnaire. |
