BACKGROUND Fifteen years after the implementation of an antenatal risk screening program in Cape Verde, the first assessment of an association between maternal obstetric characteristics and preterm birth or low birthweight (LBW) infants was undertaken. METHODS A cohort of 353 systematically selected antenatal clinic attenders in the county of Praia, Cape Verde, was studied prospectively during the period October 1991 through December 1992. The cohort was followed past the perinatal period and information was obtained according to a pretested structured questionnaire. In the analysis of preterm birth and LBW, multiple logistic regression was listed to estimate the relative risks of ll background variables. RESULTS The prevalence of preterm birth (<37 gestational weeks) was 12%, and the prevalence of LBW infants was 8%. Low birthweight (<2500 grams) was significantly associated with low maternal age (< or = 19 years, RR=3.7); nulliparity (RR=5.2) and obstetric history of previous LBW infant (RR-6.5). The risk of preterm birth was significantly increased if the woman had an obstetric history of hypertension or convulsions (RR=2.6). CONCLUSIONS In the setting studied, teenage women and women with previous pregnancy hypertension should be given selective attention in antenatal care to achieve improved pregnancy outcome. Primary prevention is needed to lower the prevalence of teenage pregnancies.

D007744	Obstetric Labor Complications	Medical problems associated with OBSTETRIC LABOR, such as BREECH PRESENTATION; PREMATURE OBSTETRIC LABOR; HEMORRHAGE; or others. These complications can affect the well-being of the mother, the FETUS, or both.

D007752	Obstetric Labor, Premature	Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011248	Pregnancy Complications	Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
