Improving postnatal checkups for mothers in West Africa: A multilevel analysis

ABSTRACT

This study examined multilevel factors related to postnatal checkups for mothers in selected West African countries. The study analyzed data from Demographic and Health Surveys (DHS) for five West African countries: Sierra Leone (2013), Cote d’Ivoire (2012), Guinea (2012), Niger (2012), and Liberia (2013). The weighted sample sizes were 2125 (Cote d’Ivoire), 2908 (Guinea), 1905 (Liberia), 5660 (Niger), and 3754 (Sierra Leone). The outcome variable was maternal postnatal checkups. The explanatory variables were community and individual/household characteristics. With the use of Stata 12, the chi-square statistic and multilevel mixed-effects logistic regression were applied. More than two-thirds of respondents in Guinea and Niger did not receive a postnatal checkup after their last birth, while in Cote d’Ivoire, Liberia, and Sierra Leone, more than half of respondents received a postnatal checkup after their last childbirth. Community characteristics accounted for the following variations in postnatal checkups: 33.9% (Cote d’Ivoire), 37.2% (Guinea), 27.0% (Liberia), 33.5% (Niger), and 37.2% (Sierra Leone). Community factors thus had important relations to use of postnatal care in West Africa. Interventions targeting more community variables, particularly community education and poverty, may further improve postnatal care in West Africa.     

Marriage law and practice in the Sahel.

The legal systems of Sahelian African countries combine customary law, Islamic law, French colonial law, and civil law introduced since independence in 1960. Utilizing a framework developed by the Faculty of Law, University of Dakar, Senegal, and the Development Law and Policy Program, Center for Population and Family Health, Columbia University, the Sahel Institute undertook a comprehensive study of the legal and social status of women in Burkina Faso, Mali, Niger, and Senegal. Since 1960, Burkina Faso, Mali, and Senegal have replaced French family law with national marriage codes. Niger has not yet adopted a family code; the laws on the family inherited from the French remain in force. The postindependence marriage codes have attempted to give young women more say in choosing a husband, to regulate the practice of bride price, and to limit the practice of polygyny. They have done this by integrating customary law and government-passed civil law. Mali, Niger, and Senegal have repealed provisions in their codes prohibiting the distribution of contraception, based on a 1920 French law. Although it has taken no formal legal action, Burkina Faso has adopted family planning policies that effectively nullify the 1920 law.     

Changes in support for the continuation of female genital mutilation/cutting and religious views on the practice in 19 countries

Campaigns to end female genital mutilation/cutting (FGM/C) have been ongoing for decades. Many countries have adopted legislation that criminalises the practice and programmatic interventions aim to reduce support for it by presenting it as a violation of human rights and by highlighting associated health risks. We used Demographic and Health Survey data from 19 countries to measure national-level trends in the prevalence of FGM/C, reported support for the continuation of the practice, and the belief that it is a religious requirement among men and women. Levels and patterns in each of these outcomes vary markedly between countries. More than half of men and women born in recent years in Guinea and Mali support the continuation of the practice and believe that it is a religious requirement. Support for the continuation of FGM/C has fallen in Benin, Burkina Faso, Chad, Egypt, Ethiopia, Kenya, Senegal, and Tanzania, but has risen in Guinea, Niger, Nigeria, and Sierra Leone. The belief that FGM/C is a religious requirement is common, particularly in countries with high prevalence of cutting. Changes in support for cutting mirror those in the belief that it is a religious requirement.     

Community Influences on Female Genital Mutilation/Cutting: A Comparison of Four Francophone West African Countries

Despite long-term efforts to encourage abandonment of female genital mutilation/cutting (FGMC), the practice remains widespread globally. FGMC is situated in specific social and historical contexts, and both prevalence and rates of decline vary widely across practicing countries. However, cross-national comparative research on the determinants of FGMC is sparse. This paper adds to the limited body of rigorous, theoretically grounded quantitative studies of FGMC and takes a step toward advancing cross-national comparative research. We apply an integrated theoretical framework that brings together norms-based and gender-based explanations of community-level influences on FGMC. We test this framework in four francophone West African countries, drawing on comparable nationally representative data from the Demographic and Health Surveys in Burkina Faso (2010), Côte d'Ivoire (2011–2012), Guinea (2012), and Mali (2012–2013). Results show that community-level FGMC norms and community-level gendered opportunities are associated with girls’ risk of FGMC, but that the direct and moderating associations vary qualitatively across countries. Our findings highlight the contribution of context-specific social and institutional processes to the decline or persistence of FGMC.     

Determinants of Early Introduction of Solid,Semi-Solid or Soft Foods among Infants Aged 3–5 Months in Four Anglophone West African Countries

This study was conducted to explore and identify factors associated with the practice of early introduction of solid, semi-solid or soft foods among infants aged 3–5 months in four Anglophone West African countries. Data sources for the analyses were the latest Demographic and Health Survey datasets of the 4 countries, namely Ghana (GDHS, 2008), Liberia (LDHS, 2007), Nigeria (NDHS, 2013) and Sierra Leone (SLDHS, 2008). Multiple logistic regression methods were used to analyze the factors associated with early introduction of solid, semi-solid or soft foods among infants aged 3–5 months, using individual-, household- and community-level determinants. The sample consisted of 2447 infants aged 3–5 months from four Anglophone West African countries: 166 in Ghana, 263 in Liberia, 1658 in Nigeria and 360 in Sierra Leone. Multivariable analyses revealed the individual factors associated with early introduction of solid, semi-solid or soft foods in these countries. These included increased infant’s age, diarrhea, acute respiratory infection and newborns perceived to be small by their mothers. Other predictors of early introduction of solid, semi-solid or soft foods were: mothers with no schooling, young mothers and fathers who worked in an agricultural industry. Public health interventions to improve exclusive breastfeeding practices by discouraging early introduction of solid, semi-solid or soft foods are needed in all 4 countries, targeting especially mothers at risk of introducing solid foods to their infants early.     

Gender differences in mobility disability during young, middle and older age in West African adults

The objective of this study was to assess the prevalence and the contribution of socio-demographic factors and chronic diseases to mobility disability in West African countries. Data were obtained from the World Health Survey (2002-2003) in which adults≥18 years participated, from Burkina Faso (n=4822), Mali (n=4230) and Senegal (n=3197). Participants reporting mild, moderate, severe, extreme difficulty or inability to move around were defined as having mobility disability. All estimates were corrected for sampling design. Association measures were estimated using logistic regression methods. Mobility disability was frequent at young ages (35-44 years old) in men and women, respectively: 17% and 23% in Burkina Faso, 12% and 23% in Mali and 22% and 34% in Senegal. Women had higher odds of mobility difficulty than men at every age group in the three countries: 1.34 (95%CI 1.06; 1.70) in Burkina Faso; 2.33 (95% CI 1.84; 2.71) in Mali and 1.82 (95%CI 1.41; 2.36) in Senegal. Controlling for socio-economic factors and chronic disease, these odds changed respectively to 0.94 (95%CI 0.70; 1.25), 2.19 (95%CI 1.61; 2.96) and 1.90 (95%CI 1.27; 2.84). These results constitute a benchmark for the study of trends of mobility disability in West Africa and could be used by policy planners.

Eliminating epidemic Group A meningococcal meningitis in Africa through a new vaccine

A new affordable vaccine against Group A meningococcus, the most common cause of large and often fatal African epidemics of meningitis, was introduced in Burkina Faso, Mali, and Niger in 2010. Widespread use of the vaccine throughout much of Africa may prevent more than a million cases of meningitis over the next decade. The new vaccine is expected to be cost-saving when compared to current expenditures on these epidemics; for example, an analysis shows that introducing it in seven highly endemic countries could save $350 million or more over a decade. International donors have already committed funds to support the new vaccine's introduction in Burkina Faso, Niger, and Mali, but an estimated US$400 million is needed to fund mass immunization campaigns in people ages 1-29 over six years in all twenty-five countries of the African meningitis belt. The vaccine's low cost--less than fifty cents per dose--makes it possible for the affected countries themselves to purchase vaccines for future birth cohorts.     

Status of pyrethroid resistance in Anopheles gambiae sensu lato

The present study confirms the presence of pyrethroid resistance among Anopheles gambiae s.l mosquitos in Côte d''Ivoire and reports the observation of such resistance in two other countries in West Africa (Benin and Burkina Faso). Malaria vector populations from Cameroon (Central Africa), Senegal (West Africa) and Botswana (southern Africa) were found to be susceptible to pyrethroids. In the most resistant mosquito populations, resistance to permethrin was associated with reduced mortality, not only with respect to this compound but also towards deltamethrin. Moreover, a significant increase in knockdown time was observed in some mosquito populations before any decrease in mortality, suggesting that knockdown time could be a good indicator for the early detection of pyrethroid resistance. In view of the current extension of such resistance, there is an urgent need to set up a network in Africa to evaluate its development. It is also vital that the impact of this resistance on pyrethroid-impregnated bednets be assessed.     

Use of Bayesian geostatistical prediction to estimate local variations in Schistosoma haematobium infection in western Africa

Objective

To predict the subnational spatial variation in the number of people infected with Schistosoma haematobium in Burkina Faso, Mali and the Niger prior to national control programmes.

Methods

We used field survey data sets covering a contiguous area 2750 × 850 km and including 26 790 school-age children (5–14 years old) in 418 schools. The prevalence of high- and low-intensity infection and associated 95% credible intervals (CrIs) were predicted using Bayesian geostatistical models. The number infected was determined from the predicted prevalence and the number of school-age children in each km².

Findings

The predicted number of school-age children with a low-intensity infection was 433 268 in Burkina Faso, 872 328 in Mali and 580 286 in the Niger. The number with a high-intensity infection was 416 009, 511 845 and 254 150 in each country, respectively. The 95% CrIs were wide: e.g. the mean number of boys aged 10–14 years infected in Mali was 140 200 (95% CrI: 6200–512 100).

Conclusion

National aggregate estimates of infection mask important local variations: e.g. most S. haematobium infections in the Niger occur in the Niger River valley. High-intensity infection was strongly clustered in western and central Mali, north-eastern and north‑western Burkina Faso and the Niger River valley in the Niger. Populations in these foci will carry the bulk of the urinary schistosomiasis burden and should be prioritized for schistosomiasis control. Uncertainties in the predicted prevalence and the numbers infected should be acknowledged by control programme planners.     

Pelvic inflammatory disease attributable to the IUD: modeling risk in West Africa

BACKGROUND: In Africa, use of the intrauterine device (IUD) is avoided because of perceived risk of pelvic inflammatory disease (PID) associated with sexually transmitted infections (STI). However, one recent model suggests that the risk of PID attributable to the IUD is very low, only 0.15% or less than 1 in 600. STUDY DESIGN: Using rates from a 2004 study of cervical STI prevalence in Benin, Burkina Faso, Ghana, Guinea, and Mali; we calculate PID risk attributable to the IUD in West Africa. RESULTS: Based on 4.4% combined prevalence of chlamydial and gonococcal infections, we estimate the risk is 0.075%, or less than 1 in 1,300. CONCLUSIONS: In West Africa, PID risk from IUDs is extremely low. This should be better communicated to family planning providers in the region who may under-provide the IUD based on erroneous perceptions of PID risk.     

Wild poliovirus importations--West and Central Africa, January 2003-March 2004

Since the 1988 World Health Assembly resolution to eradicate poliomyelitis, three World Health Organization (WHO) regions (Americas, European, and Western Pacific) have been certified polio-free, and the number of countries with endemic polio has decreased from 125 in 1988 to six in 2003 (Afghanistan, Egypt, India, Niger, Nigeria, and Pakistan). During January 2003-March 2004, importations of wild poliovirus (WPV) occurred in eight countries that were previously polio-free: five in the West African block (Benin, Burkina Faso, Cote d'Ivoire, Ghana, and Togo) and three in the Central African block (Cameroon, Central African Republic, and Chad), resulting in 63 polio cases. This report summarizes the 1) investigation and response to these WPV importations and 2) progress toward polio eradication in West and Central Africa.     

Mapping the probability of schistosomiasis and associated uncertainty, West Africa

We aimed to map the probability of Schistosoma haematobium infection being >50%, a threshold for annual mass praziquantel distribution. Parasitologic surveys were conducted in Burkina Faso, Mali, and Niger, 2004-2006, and predictions were made by using Bayesian geostatistical models. Clusters with >50% probability of having >50% prevalence were delineated in each country.     

Female circumcision: desperately seeking a space for women

Female Circumcision (FC) is "the total or partial cutting away of the female external genital organs." There are 3 types of FC: 1) Sunna where the foreskin of the clitoris is removed; 2) excision which involved removal of a part or all of the clitoris with a part or all of the labia minora; and 3) infibulation or pharaonic circumcision (the most severe type) which includes excision and removal of the labia majora only leaving a small hole to allow the exit of urine and menstrual fluid. FC carries the high risk of HIV infection because it is often practiced without anesthesia and with either a razor blade or a knife. The damages go beyond the physical--they include long-term side effects on women's physical and psychological health. The international battle against FC includes a series of legislative and political acts: 1) In 1946 the British Colonial government made one of the earliest efforts of its kind by making pharaonic circumcision in Sudan a felony and punishable by imprisonment; 2) In 1959 Egypt passed a law making circumcision illegal; 3) In 1977 the Special Committee of Non- Governmental Organizations on Human Rights of the United Nations in collaboration with WHO and UNICEF organized a sub-committee to investigate the status of women in 20 African countries and published a report; 4) In 1979 WHO held a conference in Sudan entitled "The Traditional Practices Affecting the Health of Women and Children" whose outcomes were published in a report; 5) In 1980 WHO forbade the practice of FC; 6) In 1984 a Pan-African seminar was held in Dakar, Senegal that established the Inter-African Committee Against Harmful Practices Affecting Women and Children (IAC); 7) In 1985 the UN Nairobi Conference on The Women's Decade passed resolutions against FC; 8) In 1988 the 39th Assembly of the WHO/Africa Region passed a resolution calling for the abolition of female sexual mutilation. Presidents of several African countries have condemned FC including Benin, Burkina Faso, Kenya, Senegal, Djibouti, Guinea Bissau and Mali.     

Malaria Prevalence among Young Infants in Different Transmission Settings,Africa

The prevalence and consequences of malaria among infants are not well characterized and may be underestimated. A better understanding of the risk for malaria in early infancy is critical for drug development and informed decision making. In a cross-sectional survey in Guinea, The Gambia, and Benin, countries with different malaria transmission intensities, the overall prevalence of malaria among infants <6 months of age was 11.8% (Guinea, 21.7%; The Gambia, 3.7%; and Benin, 10.2%). Seroprevalence ranged from 5.7% in The Gambia to 41.6% in Guinea. Mean parasite densities in infants were significantly lower than those in children 1–9 years of age in The Gambia (p<0.0001) and Benin (p = 0.0021). Malaria in infants was significantly associated with fever or recent history of fever (p = 0.007) and anemia (p = 0.001). Targeted preventive interventions, adequate drug formulations, and treatment guidelines are needed to address the sizeable prevalence of malaria among young infants in malaria-endemic countries.     

Glycaemic Index and Load Values Tested in Normoglycemic Adults for Five Staple Foodstuffs: Pounded Yam,Pounded Cassava-Plantain,Placali, Attieke and Maize Meal Stiff Porridge

There is currently an increased global interest in the published glycaemic index (GI) and glycaemic load (GL) values of foods. However, data on the GI and GL values of different varieties of foods within Côte d’Ivoire are very limited. The study therefore aimed at finding the GI and GL of the main food staples in Côte d’Ivoire. Following the International Standard Organisation’s protocol (ISO/FDI 26642:2010), a selection of five staple foodstuffs were tested for their GI and GL. Fasted healthy subjects were given 50 g of available carbohydrate servings of a glucose reference, which was tested twice, and test foods which were tested once, on separate occasions. Excepted attieke (GI 63), the majority of foods tested have a high GI (GI > 70). Attieke (agbodjama) had a high GL (GL 29) while placali (GL 17) and maize meal stiff porridge (GL 16) had medium GLs. The GLs of pounded cassava-plantain and pounded yam are 26 and 22. Consumption of attieke could minimize postprandial blood glucose spikes, in spite of high GL and potentially have benefit in the management and prevention of some chronic diseases.     

Assessment of poliovirus antibody seroprevalence in polio high risk areas of West Africa

We conducted a serological survey of anti-polio antibodies in polio high-risk areas of Mali, Guinea and Cote d’Ivoire to assess risk of future poliovirus outbreaks.Random community sampling of children 6–11 and 36–48 months-old was conducted; neutralizing antibodies against poliovirus were detected using microneutralization assay.We analysed 1059/1064 (99.5%) of enrolled children. Seroprevalence to poliovirus type 1 (PV1) across all age groups and locations ranged between 92 and 100%, for PV2 it was 77–100%, and 89–95% for PV3. PV2 seroprevalence in the younger age group in Guinea and Cote d’Ivoire was <80%. History of <4 polio vaccine doses and acute malnutrition were associated with seronegativity (OR = 2.1 CI95% = 1.5–3.1, OR = 1.8 CI95% = 1.1–3.3 respectively).The risk of poliovirus outbreak following importation is low because of high population immunity to PV1, however, due to large cohort of PV2 seronegative children any future detection of vaccine-derived poliovirus type 2 requires urgent response to arrest rapid spread.     

Progress toward poliomyelitis eradication--poliomyelitis outbreak in Sudan, 2004

After the World Health Assembly of the World Health Organization (WHO) resolved in 1988 to eradicate poliomyelitis globally, the number of countries in which polio is endemic declined from 125 to six by 2003. However, in 2004, polio cases caused by wild poliovirus (WPV) originating from northern Nigeria were reported in 11 countries--Benin, Botswana, Cameroon, Guinea, Mali, Saudi Arabia, Burkina Faso, Central African Republic, Chad, Cote d'Ivoire, and Sudan--reestablishing transmission in the latter five countries. Sudan, a member state of the WHO Eastern Mediterranean Region, initiated poliomyelitis eradication activities in the northern area of the country in 1994 and in the south in 1998. Since 1998, Sudan has made substantial progress in implementing polio eradication strategies, with no WPV reported from May 2001 through April 2004. However, in May 2004, a WPV case was detected in West Darfur, and a polio outbreak is currently affecting 17 of the country's 26 states. This report describes the outbreak and response and provides an update on acute flaccid paralysis (AFP) surveillance and supplementary immunization activities (SIAs) in Sudan. The outbreak underscores the importance of continued SIAs in polio-free countries with low routine vaccination coverage, even in areas with moderate to low population density, as well as the need to ensure uniformly high-quality AFP surveillance.     

Lassa Virus Seroprevalence in Sibirilia Commune,Bougouni District,Southern Mali

Lassa virus (LASV) is endemic to several nations in West Africa. In Mali, LASV was unknown until an exported case of Lassa fever was reported in 2009. Since that time, rodent surveys have found evidence of LASV-infected Mastomys natalensis rats in several communities in southern Mali, near the border with Côte d’Ivoire. Despite increased awareness, to date only a single case of Lassa fever has been confirmed in Mali. We conducted a survey to determine the prevalence of LASV exposure among persons in 3 villages in southern Mali where the presence of infected rodents has been documented. LASV IgG seroprevalence ranged from 14.5% to 44% per village. No sex bias was noted; however, seropositivity rates increased with participant age. These findings confirm human LASV exposure in Mali and suggest that LASV infection/Lassa fever is a potential public health concern in southern Mali.     

Characteristics Associated with Reliability in Reporting of Contraceptive Use: Assessing the Reliability of the Contraceptive Calendar in Seven Countries

Although the reproductive calendar is the primary tool for measuring contraceptive dynamics in low-income settings, the reliability of calendar data has seldom been evaluated, primarily due to the lack of longitudinal panel data. In this research, we evaluated the reproductive calendar using data from the Performance Monitoring for Action Project. We used population-based longitudinal data from nine settings in seven countries: Burkina Faso, Nigeria (Kano and Lagos States), Democratic Republic of Congo (Kinshasa and Kongo Central Provinces), Kenya, Uganda, Cote d'Ivoire, and India. To evaluate reliability, we compared the baseline cross-sectional report of contraceptive use (overall and by contraceptive method), nonuse, or pregnancy with the retrospective reproductive calendar entry for the corresponding month, measured at follow-up. We use multivariable regressions to identify characteristics associated with reliability or reporting. Overall, we find that the reliability of the calendar is in the “moderate/substantial” range for nearly all geographies and tests (Kappa statistics between 0.58 and 0.81). Measures of the complexity of the calendar (number of contraceptive use episodes, using the long-acting method at baseline) are associated with reliability. We also find that women who were using contraception without their partners/husband's knowledge (i.e., covertly) were less likely to report reliably in several countries.
