ABSTRACT

Childhood mortality and morbidity patterns in the English-speaking Caribbean have changed significantly over the past 40 years. Acute respiratory illness, physical injury and conditions originating in the perinatal period have replaced malnutrition, gastroenteritis and other infectious diseases as major causes of illness and death in Caribbean children. Although population growth has slowed down, about one-third of the population of the English-speaking Caribbean remains under the age of 15 years. Infant mortality rates have also fallen but the major contributor to this decline has been a reduction in post-neonatal deaths. The decrease in mortality and morbidity from infectious diseases has led to a prominence of disorders originating in the perinatal period, psychosocial problems and chronic childhood disorders. Adverse economic conditions are held culpable for the re-emergence of protein energy malnutrition (PEM) and pulmonary tuberculosis in some territories. There is an urgent need to focus attention on the areas of perinatal and adolescent health, childhood disability, accidental and non-accidental injury, sexual abuse and human immunodeficiency virus (HIV) infection. Immunization programmes also require continuing support and expansion. These tasks cannot be accomplished without meaningful long term investment of financial and human resources in the health and educational services of the region.

ABSTRACT

A multicenter cohort study was designed to assess pregnancy outcome among natural family planning (NFP) users, and provide the opportunity to address complications in NFP users by planning status and by timing of conception with respect to day of ovulation. There were 877 singleton births in this sample. Complications evaluated were abnormal vaginal bleeding, urinary tract infection, vaginal infection, hypertension of pregnancy, proteinuria, glycosuria, and anemia. There was no significant difference in the mean age, number of prenatal visits or birth weight among optimally and non-optimally timed pregnancies or for planned and unplanned pregnancies. There were higher incidences of "parity 2 or more" and current smokers in the non-optimally timed pregnancies and lower incidences of prior pregnancy loss and "currently employed" in the non-optimally timed pregnancies. There was little difference in pregnancy complications with respect to pregnancy timing, with the exception of a significant increased risk of vaginal bleeding late in pregnancy among non-optimally timed conceptions (11.5%) compared to optimally timed pregnancies (5.2%, RR = 2.2, 95% CI 1.3-3.7). More differences were observed in pregnancy complication rates by planning status. Unplanned pregnancies were associated with significantly more late pregnancy bleeding, vaginal infections, proteinuria, glycosuria and medication use than planned pregnancies. Unplanned pregnancies had lower incidences of maternal anemia. Complications of pregnancy were low in this NFP population, irrespective of planned versus unplanned status. Women with planned pregnancies had even fewer complications during pregnancy than women with unplanned conceptions, suggesting that women using NFP to plan their reproduction may be at particularly low risk.

ABSTRACT

An institution-based surveillance and nested case-control study was conducted in Natal, Northeastern Brazil to estimate the level and determinants of early neonatal mortality. The early neonatal mortality rate was 25.5 per 1000 live-birth, 75% of early neonatal deaths were premature low birthweight infants, and the mortality rates were 591 and 318 per 1000 respectively, for preterm small for gestational age (PT-SGA) and preterm appropriate for gestational age (PT-AGA) infants. Mortality was 50 per 1000 for term low birthweight, and 8.6 for term normal birthweight AGA infants. In addition to prematurity and low birthweight, the main risk factors associated with early neonatal death were maternal smoking, complications during pregnancy or intrapartum, and inadequate antenatal care. The associations were weaker for prepregnancy factors such as single marital status or low maternal body weight, and no significant associations were observed with socioeconomic status. These findings suggest that in this population, efforts to reduce early neonatal death should focus on improved maternal care and the prevention of prematurity.


PIP: To facilitate health service planning, a surveillance and case-control study were conducted of births in 3 hospitals and 2 maternity clinics in the city of Natal in northeastern Brazil. The surveillance study revealed 285 early neonatal deaths among the 111,171 singleton live births recorded in the study institutions from September 1984-February 1986, for a rate of 25.5/1000. 75% of these early neonatal deaths involved premature infants. The mortality rates were 591/1000 for preterm small-for-gestational age infants and 318/1000 for preterm appropriate-for-gestational age infants, while this rate was 50/1000 for term low-birthweight infants and only 8.6/1000 for term normal birthweights infants. The case-control study indicated that the maternal risk factors of body weight under 50 kg and single parent status significantly increased the likelihood of early neonatal mortality, while maternal age, parity, prior reproductive loss, and socioeconomic status did not have a significant effect on this outcome. Pregnancy-related factors that substantially increased the risk of early neonatal death included smoking, bleeding during the first or second trimester, toxemia, less than 5 prenatal care visits, and congenital malformations. These pregnancy-related risks exerted a more substantial effect than maternal characteristics, suggesting the feasibility of a strategy focused on preventing preterm births through prenatal care rather than a high-risk approach of screening women prior to pregnancy.

ABSTRACT

An institution based case-control study to determine risk factors for stillbirths was conducted in the city of Natal, NE Brazil, where 90% of deliveries take place in health facilities. Two hundred thirty-four singleton stillborn cases were compared to 2555 liveborn singleton control infants of normal birth-weight and gestational age. Information was obtained by postnatal interview and anthropometry, and review of medical records. Univariate analyses revealed a large number of potential risk factors, but after adjustment by logistic regression only six factors remained significantly associated with stillbirth. These were low maternal weight, less than or equal to 50 kg and a history of pregnancy loss, both with odds ratios (OR) of 1.8, inadequate prenatal care defined as less than five visits (OR = 1.9), gestational complications (OR = 14.2), intrapartum complications (OR = 2.0), and congenital malformations (OR = 8.7). There was also an increased risk of stillbirth among older mothers who smoked (OR = 1.4), and evidence of an interaction between smoking and complications of pregnancy. From the public health perspective, the most important factors amenable to intervention were inadequate prenatal care and antenatal or intrapartum complications which were associated with substantial attributable risks (23.8%, 35.2%, and 10.2%, respectively). Thus, in this population, future reductions of the high stillbirth rate (27.2 per 1000 births) will largely depend on the coverage, utilization, and quality of antenatal and intrapartum care.

ABSTRACT

A case-control study was conducted in Natal, north-east Brazil to determine the risk factors for low birthweight (LBW). Cases were 429 preterm and 422 intrauterine growth retarded (IUGR) singleton infants. Controls were 2555 infants of normal birthweight and gestational age. The prevalence of LBW was 10% (5.1% preterm and 4.9% IUGR). Logistic regression was used to estimate the adjusted odds ratios of LBW, and attributable risk per cent (AR%) was used to estimate the proportion of LBW that might be prevented. The preventable determinants of preterm delivery were births to women less than 20, (AR = 7.1%), low maternal weight less than 50 kg (AR = 20.5%), smoking during pregnancy (AR = 14.6%) and infrequent antenatal visits (AR = 28.1%). Other important determinants of preterm delivery were prior LBW births, gestational illness and vaginal bleeding. The main preventable causes of IUGR were low maternal weight (AR = 17.8%), low maternal education (AR = 11.6%), smoking (AR = 14.8%), and inadequate antenatal care (AR = 11.6%). Other risk factors for IUGR include primiparity, prior LBW births, and illness during gestation. In this population, the focus of short-term preventive programme should be improvement in maternal nutrition, cessation of smoking, reduction of births to women under 20, and improved antenatal care.

ABSTRACT

In a case-control study in Natal, northeast Brazil, conducted between September 1984 and February 1986, 303 cases of intrauterine growth retardation and 282 cases of preterm delivery were compared with 1,710 normal controls to ascertain the effects of the preceding birth-to-conception interval on pregnancy outcome. The risk of intrauterine growth retardation associated with interpregnancy intervals of six months or less was 1.38 (95% confidence interval (CI): 1.02-1.86) after adjustment for maternal age, education, smoking, and prior fetal loss or low birth weight. When maternal postpartum body weight was introduced into the logistic model, the risk of intrauterine growth retardation decreased slightly to 1.25 and was no longer significant (95% CI: 0.91-1.72). Short interpregnancy intervals (six months or less) were more frequently observed in women with postpartum body weight of less than 45 kg (31.1%) than in women weighing 50 kg or more (18.9%), which might suggest that the effect of short intervals on the risk of intrauterine growth retardation is mediated through maternal nutritional status. No association was found between birth-to-conception intervals and preterm delivery.

ABSTRACT

The outcome of 124 pregnancies produced during the use of CM (Billings) of NFP is analyzed. The spontaneous abortion rate was 8%. The women who became pregnant in the less fertile period (+/- 3 days from peak day) presented a higher rate of spontaneous abortions (13.9%) than the women who became pregnant during the most fertile period (peak day +/- 2 days), who presented a 4.3% spontaneous abortion rate. Among the 115 living infants (one twin pregnancy) there was one congenital malformation (0.8%), a cleft palate. The sex ratio of the infants was 0.59 (48 females and 67 males), which is not significantly different from the 0.51 sex ratio expected. When conception occurred during the most fertile period, the sex ratio was 0.37, in contrast to the sex ratio of 0.76 when conception occurred in the less fertile period; this is a highly significant difference (P less than 01).

ABSTRACT

PIP: The effects of enriched maternal nutrition on postpartum lactation amenorrhea, and consequently on fertility, must not be exaggerated. Recent studies conducted in Bangladesh and Guatemala showed that average duration of lactational amenorrhea in poorly nourished women was only 1-1.5 months longer than in women with higher nutritional status. Thus, even if maternal nutrition was much improved, it is unlikely that it would result in a marked reduction of birth spacing. Only one study, conducted in Mexico, showed a decrease in lactation amenorrhea when both mother and infant had received additional food. This was due to the reduced need for breast milk, which led to a decline in frequency and intensity of suckling required to maintain high prolactin levels. Only under these circumstances could infant feeding programs have an effect on fertility, and contraceptive services should be provided at the same time.^ieng
