[Reducing maternal mortality in developing countries: theory and practice].

Chiefs of state attending the Millennium Summit (2000) set a goal of reducing maternal mortality by 75% before 2015. Based on knowledge of the epidemiology of maternal mortality/morbidity and on growing experience in the field, the international community defined a relatively low-cost program of evidence-based initiatives. However implementation of that program has been stymied by the reality that increasing geographical accessibility to a full range of quality emergency obstetric care of quality will require large investments of money and time. Increasing financial accessibility remains difficult given the low standard of living of populations and budget cutbacks by national governments. The problems facing women and health workers are mostly overlooked by public health policy. There is need for a multi-disciplinary approach with equal participation of specialists in public health, gyneco-obstetrics, anthropology, health care economics, political science and social and community mobilization.

[Determinants of risk factors associated with severe maternal morbidity: application during antenatal consultations].

In order to assess the incidence of severe maternal mortality (SMM) and search for associated determinants of risk factors, a population-based survey of 20,326 pregnant women was conducted in six counties in West Africa (MOMA study). Complete files were available for 19,545 (96.2%) women. The rate of SMM, assessed with an overall indicator, was 6.7% (5.7-6.4). The relationship between SMM and various socio-economic features, gyneco-obstetrical antecedents and characteristics of the current pregnancy was studied. Multivariate analysis identified 10 factors of risk of SMM. Prevalence, adjusted odds-ratio, positive predictive value and adjusted attributable risk were determined for these ten factors. By decreasing order of positive predictive value, these factors were: hemorrhage during pregnancy (51.5%), antecedent cesarean (27.1%), high blood pressure (diastolic pressure 10 (18.9%), systolic pressure 14 (14.6%)), antecedent multiple pregnancy (15.8%), height 150 cm (12.9%), lack of fetal movements (12.6%), history of 3 stillborns (9.3%), age over 35 years (8%), nulliparity (7.3%), presence of disease during the pregnancy (7.1%). These results show the importance of antenatal consultation during which these factors are easily identifiable.

[Potential role of prenatal care in reducing maternal and perinatal mortality in sub-Saharan Africa].

Prenatal care has been implemented in developing countries according to the same mode as applied in industrialized countries without considering its real effectiveness in reducing maternal and neonatal mortality. Several recent studies suggest that the goals should be revisited in order to implement a program of prenatal care based on real scientific evidence. Based on the current literature, we propose a potentially effective content for prenatal care adapted to the context of developing countries. Four antenatal consultations would be enough if appropriately timed at 12, 26, 32 and 36 weeks pregnancy. The purpose of these consultations would be: 1) to screen for three major risk factors, which, when recognized, lead to specific action: uterine, scare, malpresentation, premature rupture of the membranes; 2) to prevent and/or detect (and treat) specific complications of pregnancy: hypertension, infection (malaria, venereal disease, HIV, tetanus, urinary tract infection); anemia and trace element deficiencies, gestational diabetes mellitus; 3) to provide counseling, support and information for pregnant women and their families (including the partner) concerning: severe signs and symptoms of pregnancy and delivery, community organization of emergency transfer, delivery planning. These potentially effective actions can only have a real public health impact if implemented within an organized maternal health system with a functional network of delivery units, if truly quality care is given, and if the relationships between health care providers and the population are based on mutual respect. Sub-Saharan African women use prenatal care extensively when it is accessible; this opportunity must be used to implement evidence-based actions with appropriate and realistic goals.

Risk factors for perinatal mortality in West Africa: a population-based study of 20326 pregnancies. MOMA group.

UNLABELLED: The aim of the study was to identify simple clinical risk factors for perinatal mortality (PNM) in different areas of West Africa, to quantify their prevalence among pregnant women and to estimate their relative contribution in the definition of high-risk status of PNM. The MOMA study was a prospective population-based study in which data were collected on 20 326 pregnant women in various, primarily urban, areas of Burkina Faso, Ivory Coast, Mali, Mauritania, Niger and Senegal. The present report analyses 19 870 singleton births and 31 simple clinical variables with univariate and multivariate methods. The mean PNM ratio was 42 per 1000 total births, and 62% of these deaths were stillbirths. In the crude analysis, after adjustment or taking prevalence into account, the principal risk factors were: vaginal bleeding (immediately antenatal and intrapartum), hypertension (especially during labour), dynamic (prolonged labour and use of oxytocin) and mechanic (non-cephalic presentation) dystocia, and infection (prolonged rupture of the membranes and intrapartum fever). CONCLUSIONS: Most of the principal risk factors for PNM cannot be detected during antenatal care visits but only in early labour. High-risk status should not be based solely on antenatal care visits, but should also take into account monitoring during labour.

The quality of risk factor screening during antenatal consultations in Niger.

A decade after the first International Conference on Safe Motherhood, maternal mortality remains very high in most West African countries, even in capital cities. The detection of high risk pregnancies, known as the risk approach, during antenatal consultations has been the basis of most maternal and child health programmes over the last decade. The effectiveness of antenatal care as a tool to prevent or predict obstetric complications is being questioned more and more. In addition to the scarcity of reliable data about the predictivity of most risk factors, the quality of the screening must be questioned. The goal of this study was to assess the frequency of risk factors among a sample of pregnant women attending antenatal care in Niger and to assess the quality of the screening of those risk factors. Overall, 330 pregnant women were enrolled in the study. Each woman was examined twice: the first time by a midwife, the second time by one of the authors but without knowledge of the results of the first consultation. Fifty-five percent of pregnant women had at least one risk factor, 31% had more than one. Ninety-one percent of the risk factors were detected at interview. The following risk factors were not systematically searched for by midwives: height (48.5%), blood pressure (43.6%), glycosuria (40.6%), vaginal bleeding (38.2%), oedema (37.3%), parity (17%), age (16%), previous caesarean section (15.2%), previous stillbirth (15.2%) and previous miscarriages (14.8%). This study has shown that, in Niger, the quality of screening for risk factors during antenatal consultation is poor. In the urban settings where this study took place, lack of personnel, lack of equipment, lack of time and poor compliance by women cannot be made responsible for this situation. While screening of these risk factors continues as policy, the quality of screening must be dramatically improved.

Severe maternal morbidity from direct obstetric causes in West Africa: incidence and case fatality rates.

Data on maternal morbidity make it possible to assess how many women are likely to need essential obstetric care, and permit the organization, monitoring and evaluation of safe motherhood programmes. In the present paper we propose operational definitions of severe maternal morbidity and report the frequency of such morbidity as revealed in a population-based survey of a cohort of 20,326 pregnant women in six West African countries. The methodology and questionnaires were the same in all areas. Each pregnant woman had four contacts with the obstetric survey team: at inclusion, between 32 and 36 weeks of amenorrhoea, during delivery and 60 days postpartum. Direct obstetric causes of severe morbidity were observed in 1215 women (6.17 cases per 100 live births). This ratio varied significantly between areas, from 3.01% in Bamako to 9.05% in Saint-Louis. The main direct causes of severe maternal morbidity were: haemorrhage (3.05 per 100 live births); obstructed labour (2.05 per 100), 23 cases of which involved uterine rupture (0.12 per 100); hypertensive disorders of pregnancy (0.64 per 100), 38 cases of which involved eclampsia (0.19 per 100); and sepsis (0.09 per 100). Other direct obstetric causes accounted for 12.2% of cases. Case fatality rates were very high for sepsis (33.3%), uterine rupture (30.4%) and eclampsia (18.4%); those for haemorrhage varied from 1.9% for antepartum or peripartum haemorrhage to 3.7% for abruptio placentae. Thus at least 3-9% of pregnant women required essential obstetric care. The high case fatality rates of several complications reflected a poor quality of obstetric care.

[Pregnancy and delivery in western Africa. High risk motherhood].

According to the World Health Organization, 585,000 women die each year from a pregnancy-related cause, 99% of whom are from developing countries. The first International Conference on Safe Motherhood in 1987 sensitized the world community to this drama. Ever since, maternal mortality and its medical causes are better known. The maternal mortality ratio is highest in West Africa (1,020 maternal deaths per 100,000 live borns) when it is 27/100,000 in industrialized countries. Direct obstetric causes account for 80% of the deaths: hemorrhage, infection, dystocia, hypertension and abortion. Indirect causes are essentially anemia, malaria, hepatitis C and AIDS. Severe maternal morbidity is 6 to 10 times more frequent than maternal mortality but it also leads to handicaps which end up often in women's social rejection. However, WHO estimates that 95% of these deaths and handicaps are avoidable, and at a low cost.

[Pregnancy and delivery in western Africa. Towards a lower risk motherhood?].

The maternal mortality ratio is the health indicator displaying the greatest disparity between industrialized and developing countries. Medical causes have been better known since a decade ago but the non medical causes must be studied to develop appropriate strategies. Socio-economic causes play an important role but the poor performances of the maternal health services are directly responsible for the great majority of the deaths. The lack of qualified personnel, the poor management of those who are qualified, the misallocation of the rare resources, the poor relationships between health personnels and their clients, the shortages of supplies, essential drugs and blood lead to a poor quality of care to pregnant women. The Safe Motherhood Initiative has led to the development of simple but efficient strategies which would allow to dramatically reduce maternal and neonatal mortality as well as handicaps. This requires a political commitment of the governments of West Africa but, in spite of the strong advocacy of major donor agencies and international organizations, programs have yet to be implemented.

Severe obstetric morbidity of the third trimester, delivery and early puerperium in Niamey (Niger).

Epidemiological data about maternal morbidity are rare. The present study, carried out in Niamey, capital of Niger, was designed to measure the incidence of maternal morbidity among women delivering in hospital. Severe complications occurred in 232 of the 4,081 deliveries during the study period (6,450/100,000 live births). Maternal morbidity ratio was 11 times higher than the maternal mortality ratio. Incidence rates of the major morbidities (per 100,000 live births) were: obstructed labour 3,614, hypertensive disorders of pregnancy 1,159, haemorrhage 855, and puerperal sepsis 220. The incidence and case fatality rates of severe complications were both high, suggesting a lack of efficiency of maternal health services in spite of a high concentration of health personnel and a large accessibility to services in Niamey.

Effect of iron supplementation on the iron status of pregnant women: consequences for newborns.

We studied the effect of iron supplementation on the iron status of mothers and on biochemical iron status and clinical and anthropometric measures in their infants. The subjects were 197 pregnant women selected at 28 wk +/- 21 d of gestation at a mother-and-child health center in Niamey, Niger. Ninety-nine women received 100 mg elemental Fe/d throughout the remainder of their pregnancies and 98 received placebo. The prevalence of anemia and iron deficiency decreased markedly during the last trimester of pregnancy in the iron-supplemented group but remained constant in the placebo group. Three months after delivery, the prevalence of anemia was significantly higher in the placebo group. At delivery, there were no differences between the two groups in cord blood iron variables. Three months after delivery, serum ferritin concentrations were significantly higher in infants of women in the iron-supplemented group. Mean length and Apgar scores were significantly higher in infants with mothers in the iron group than in those with mothers in the placebo group.

Midwives in Niger: an uncomfortable position between social behaviours and health care constraints.

Maternal mortality rates are very high in developing countries. In Niamey, the capital of Niger, maternal mortality rate is 280/100,000, in spite of a high concentration of health services and of health personnel. Several studies demonstrated that the efficiency of maternal health services was low, both because the quality and the quantity of work were insufficient. The usual response to the poor performances of health services in developing countries is mainly technical. If improvement of the training of health personnel and re-organization of health services are necessary, they are not sufficient. A good effectiveness of care cannot be achieved without a mutual confident relationship between providers and patients. Focus group discussions were held in Niamey with women users of maternal health services, with student midwives and experienced midwives. Sources of complaints between providers and patients appeared to be numerous. However, they are centered around two themes, delivery techniques and cultural requirements, which correspond to two types of constraints: technical constraints and social representations and practices of the population. A description of traditional practices and beliefs related to delivery were obtained through discussion groups with old women and traditional birth attendants (TBAs). Both women and midwives are tied up by the same social rules (e.g. linguistic taboos, respect and shame) but technical constraints force midwives to violate those rules, making the application of their technical skills very difficult. Thus, the mutual relationship between users and providers is source of dissatisfaction, which often degenerates into an open confrontation. Midwives must learn how to implement obstetrical techniques within specific cultural environments.

Traditional uvulectomy in Niger: a public health problem?

Although traditional uvulectomy, a procedure which consists of cutting away a part of the uvula, has been reported in several sub-Saharan African countries, in Maghreb and in Israel, epidemiological and anthropological data on this practice are rare. Severe complications may require hospitalization. The goal of this study was to assess the prevalence of this traditional procedure in Niamey, capital of Niger, the incidence of its severe complications and the beliefs and practices related to it. By the age of 5, 19.6% of the children in our survey had undergone uvulectomy. Severe complications of uvulectomy represented 7.8/1000 cases of hospitalization for children under 15 years of age. Complications were infections (including tetanus), hemorrhage and passage of the cut piece of uvula further down the respiratory tract. The children who had undergone uvulectomy belonged significantly more often to the Hausa ethnic group (66.2%) than to the majority Zarma ethnic group (18.3%) or to the other ethnic groups (15.5%). This can be explained by the fact that, in some Hausa subgroups, uvulectomy is systematically performed on the 7th day after birth, during the naming ceremony, to prevent death due to a 'swelling of the uvula'. In the other Hausa sub-groups and in the other ethnic groups, uvulectomy is solely a curative practice, both for children and adults, for vomiting, diarrhea, anorexia, the child's rejection of the breast, growth retardation and fever. Uvulectomy is performed in Niger by the barbers, whose functions are also to perform specialized surgery. These traditional surgeons claim there is no risk to this practice.(ABSTRACT TRUNCATED AT 250 WORDS)

Are pediatric wards in developing countries only places to die? A study of prior to hospitalization risk factors of death among 0-2 year old hospitalized children in Niamey, capital of Niger.

The 461 0-2-year-old children admitted to the paediatric ward of the National Hospital in Niamey over a 2-month period were closely followed up from admission to discharge or death. The in-hospital mortality rate was 30 per cent, a great proportion of deaths occurring during the first 24 h of hospitalization. Malnutrition was highly prevalent (76 per cent). Children referred from other health facilities (72 per cent) did not experience a higher probability of survival. Using multivariate analysis, three variables remained significantly associated with death: nutritional status, consultation of a traditional practitioner, and a neonate disease. Neonate diseases are the third major cause of death because of a high case fatality rate. For the other causes, the main underlying factor is malnutrition. Most in-hospital deaths are due to events that occurred prior to hospitalization. The role of hospitals' pediatric wards of developing countries is discussed.

Randomized clinical trial comparing hospital to ambulatory rehabilitation of malnourished children in Niger.

This study compared hospital to ambulatory nutritional rehabilitation outcomes and costs. Following a hospital stay to resolve initial acute medical conditions, 100 malnourished children (54 per cent male, ages 5 to 28 months) in Niger were randomly assigned to either hospital or ambulatory nutritional rehabilitation. Anthropometric measures were assessed at 15, 30, 60, 90 and 180 days post-randomization. Following randomization, the hospital group received a mean of 12.9 days of hospital rehabilitation and 5.6 days of ambulatory rehabilitation, while the ambulatory group received 2.2 days of hospital rehabilitation and 11.9 days of ambulatory rehabilitation. No significant differences between the two study groups in mortality rates or weight gain were found. The mean cost for hospital rehabilitation was 120 per cent higher (P < 0.001) than ambulatory rehabilitation. This study was the first randomized clinical trial directly comparing hospital to ambulatory nutritional rehabilitation and suggests that ambulatory rehabilitation is more cost-effective.

Effect of iron supplementation during pregnancy on trace element (Cu, Se, Zn) concentrations in serum and breast milk from Nigerian women.

Trace element concentrations in serum and breast milk were studied longitudinally in 197 Nigerian women from 6 months of gestation to 6 months postpartum; 99 of them received a daily iron supplement of 100 mg from 6 months of gestation to delivery. During the last 3 months of pregnancy, serum selenium declined, whereas serum zinc remained unchanged and serum copper increased. After delivery, copper concentration in maternal serum decreased, whereas serum zinc increased from delivery to 3 months postpartum and then reached a plateau. Serum selenium increased from delivery to 6 months postpartum. In breast milk, selenium and zinc decreased from 5 days to 6 months postpartum. Copper in breast milk also declined during the course of lactation but reached a plateau by 3 months postpartum. Iron concentration in breast milk remained unchanged during the study. Iron supplementation had no significant effect upon the concentrations of copper, selenium and zinc in mother serum and breast milk. In umbilical serum, iron status, copper and zinc levels were similar in the two groups, whereas, unexpectedly, selenium concentration was significantly decreased (p < 0.03) in the iron-supplemented group. Taken together, our results suggest that the beneficial effect of iron supplementation on iron deficiency was not associated with an adverse effect on copper and zinc status. On the other hand, our results suggest that Nigerian women had a marginal zinc status but an adequate selenium status.
