The impact of community delivery of intermittent preventive treatment of malaria in pregnancy on its coverage in four sub-Saharan African countries (Democratic Republic of the Congo, Madagascar, Mozambique, and Nigeria): a quasi-experimental multicentre evaluation.

BACKGROUND: Intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine is recommended at each antenatal care clinic visit in high-moderate transmission areas. However, its coverage remains unacceptably low in many countries. Community health workers can effectively deliver malaria preventive interventions. The aim of this study was to assess the effect of community delivery of IPTp (C-IPTp) on antenatal care and IPTp coverage. METHODS: A community-based IPTp administration approach was implemented in four sub-Saharan countries: the Democratic Republic of the Congo (DR Congo), Madagascar, Mozambique, and Nigeria. A quasi-experimental before and after evaluation by cluster sampling was designed where C-IPTp was implemented in selected country areas in different phases. Baseline (before C-IPTp implementation), midline, and endline household surveys were carried out to assess IPTp intake in pregnant women in 2018, 2019, and 2021. Eligible participants of the household survey were women of reproductive age (13-50 years old, depending on the country) that had a pregnancy that ended (any pregnancy regardless of pregnancy outcome) in the 6 months before the interview. For the first baseline surveys, the target population was women who had a pregnancy that ended in the 12 months before the interview. The primary outcome from the household surveys was the proportion of women who reported having received at least three doses of IPTp during pregnancy. The trial is registered at ClinicalTrials.gov, NCT03600844. FINDINGS: A total of 32 household surveys were conducted between March 15, and Oct 30, 2018, and data from 18 215 interviewed women were analysed. The coverage of at least three doses of IPTp (IPTp3+) increased after the first year of C-IPTp implementation in all project areas in DR Congo (from 22·5% [170/755] to 31·8% [507/1596]), Madagascar (from 17·7% [101/572] to 40·8% [573/1404]), and Nigeria (from 12·7% [130/1027] to 35·2% [423/1203]), with increases between 145·6% (Madagascar) and 506·6% (Nigeria). IPTp3+ coverage increased between baseline and endline in all districts, except for Murrupula (Mozambique) and ranged between 9·6% and 533·6%. This pattern was similar in DR Congo, Madagascar, and Nigeria, and in Mozambique, the increase was lower than the other countries. Antenatal care attendance did not change or increased lightly in all study countries. INTERPRETATION: C-IPTp was associated with an increase in IPTp uptake without reducing antenatal care attendance. The strategy might be considered for malaria control in pregnancy. FUNDING: UNITAID [2017-13-TIPTOP].

Coverage of intermittent preventive treatment of malaria in pregnancy in four sub-Saharan countries: findings from household surveys.

BACKGROUND: Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is a key malaria prevention strategy in areas with moderate to high transmission. As part of the TIPTOP (Transforming IPT for Optimal Pregnancy) project, baseline information about IPTp coverage was collected in eight districts from four sub-Saharan countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria. METHODS: Cross-sectional household surveys were conducted using a multistage cluster sampling design to estimate the coverage of IPTp and antenatal care attendance. Eligible participants were women of reproductive age who had ended a pregnancy in the 12 months preceding the interview and who had resided in the selected household during at least the past 4 months of pregnancy. Coverage was calculated using percentages and 95% confidence intervals. RESULTS: A total of 3911 women were interviewed from March to October 2018. Coverage of at least three doses of IPTp (IPTp3+) was 22% and 24% in DRC project districts; 23% and 12% in Madagascar districts; 11% and 16% in Nigeria local government areas; and 63% and 34% in Mozambique districts. In DRC, Madagascar and Nigeria, more than two-thirds of women attending at least four antenatal care visits during pregnancy received less than three doses of IPTp. CONCLUSIONS: The IPTp3+ uptake in the survey districts was far from the universal coverage. However, one of the study districts in Mozambique showed a much higher coverage of IPTp3+ than the other areas, which was also higher than the 2018 average national coverage of 41%. The reasons for the high IPTp3+ coverage in this Mozambican district are unclear and require further study.

Child malnutrition in Ifanadiana district, Madagascar: associated factors and timing of growth faltering ahead of a health system strengthening intervention.

BACKGROUND: Child malnutrition, a leading cause of death and disability worldwide, is particularly severe in Madagascar, where 47% of children under 5 years are stunted (low height-for-age) and 8% are wasted (low weight-for-height). Widespread poverty and a weak health system have hindered attempts to implement life-saving malnutrition interventions in Madagascar during critical periods for growth faltering. OBJECTIVE: This study aimed to shed light on the most important factors associated with child malnutrition, both acute and chronic, and the timing of growth faltering, in Ifanadiana, a rural district of Madagascar. METHODS: We analyzed data from a 2014 district-representative cluster household survey, which had information on 1175 children ages 6 months to 5 years. We studied the effect of child health, birth history, maternal and paternal health and education, and household wealth and sanitation on child nutritional status. Variables associated with stunting and wasting were modeled separately in multivariate logistic regressions. Growth faltering was modeled by age range. All analyses were survey-adjusted. RESULTS: Stunting was associated with increasing child age (OR = 1.03 (95%CI 1.02-1.04) for each additional month), very small birth size (OR = 2.32 (1.24-4.32)), low maternal weight (OR = 0.94 (0.91-0.97) for each kilogram, kg) and height (OR = 0.95 (0.92-0.99) for each centimeter), and low paternal height (OR = 0.95 (0.92-0.98)). Wasting was associated with younger child age (OR = 0.98 (0.97-0.99)), very small birth size (OR = 2.48 (1.23-4.99)), and low maternal BMI (OR = 0.84 (0.75-0.94) for each kg/m2). Height-for-age faltered rapidly before 24 months, then slowly until age 5 years, whereas weight-for-height faltered rapidly before 12 months, then recovered gradually until age 5 years but did not reach the median. CONCLUSION: Intergenerational transmission of growth faltering and early life exposures may be important determinants of malnutrition in Ifanadiana. Timing of growth faltering, in the first 1000 days, is similar to international populations; however, child growth does not recover to the median.

In Madagascar, Use Of Health Care Services Increased When Fees Were Removed: Lessons For Universal Health Coverage.

Despite overwhelming burdens of disease, health care access in most developing countries is extremely low. As governments work toward achieving universal health coverage, evidence on appropriate interventions to expand access in rural populations is critical for informing policies. Using a combination of population and health system data, we evaluated the impact of two pilot fee exemption interventions in a rural area of Madagascar. We found that fewer than one-third of people in need of health care accessed treatment when point-of-service fees were in place. However, when fee exemptions were introduced for targeted medicines and services, the use of health care increased by 65 percent for all patients, 52 percent for children under age five, and over 25 percent for maternity consultations. These effects were sustained at an average direct cost of US$0.60 per patient. The pilot interventions can become a key element of universal health care in Madagascar with the support of external donors.

Baseline population health conditions ahead of a health system strengthening program in rural Madagascar.

BACKGROUND: A model health district was initiated through a program of health system strengthening (HSS) in Ifanadiana District of southeastern Madagascar in 2014. We report population health indicators prior to initiation of the program. METHODS: A representative household survey based on the Demographic Health Survey was conducted using a two-stage cluster sampling design in two strata - the initial program catchment area and the future catchment area. Chi-squared and t-tests were used to compare data by stratum, using appropriate sampling weights. Madagascar data for comparison were taken from a 2013 national study. RESULTS: 1522 households were surveyed, representing 8310 individuals including 1635 women ages 15-49, 1685 men ages 15-59 and 1251 children under age 5. Maternal mortality rates in the district are 1044/100,000. 81% of women's last childbirth deliveries were in the home; only 20% of deliveries were attended by a doctor or nurse/midwife (not different by stratum). 9.3% of women had their first birth by age 15, and 29.5% by age 18. Under-5 mortality rate is high: 145/1000 live births vs. 62/1000 nationally. 34.6% of children received all recommended vaccines by age 12 months (compared to 51.5% in Madagascar overall). In the 2 weeks prior to interview, approximately 28% of children under age 5 had acute respiratory infections of whom 34.7% were taken for care, and 14% of children had diarrhea of whom 56.6% were taken for care. Under-5 mortality, illness, care-seeking and vaccination rates were not significantly different between strata. CONCLUSIONS: Indicators of population health and health care-seeking reveal low use of the formal health system, which could benefit from HSS. Data from this survey and from a longitudinal follow-up study will be used to target needed interventions, to assess change in the district and the impact of HSS on individual households and the population of the district.

Modeling the burden of poultry disease on the rural poor in Madagascar.

Livestock represent a fundamental economic and nutritional resource for many households in the developing world; however, a high burden of infectious disease limits their production potential. Here we present an ecological framework for estimating the burden of poultry disease based on coupled models of infectious disease and economics. The framework is novel, as it values humans and livestock as co-contributors to household wellbeing, incorporating feedbacks between poultry production and human capital in disease burden estimates. We parameterize this coupled ecological-economic model with household-level data to provide an estimate of the overall burden of poultry disease for the Ifanadiana District in Madagascar, where over 72% of households rely on poultry for economic and food security. Our models indicate that households may lose 10-25% of their monthly income under current disease conditions. Results suggest that advancements in poultry health may serve to support income generation through improvements in both human and animal health.
