Little is known about the outcomes of subjects with a history of severe acute malnutrition (SAM). We therefore sought to explore the long-term effects of SAM during childhood on human capital in adulthood in terms of education, cognition, self-esteem and health-related disabilities in daily living.
We traced 524 adults (median age of 22) in the eastern Democratic Republic of the Congo, who were treated for SAM during childhood at Lwiro hospital between 1988 and 2007 (median age 41 months). We compared them with 407 community controls of comparable age and sex. Our outcomes of interest were education, cognitive function [assessed using the Mini Mental State Examination (MMSE) for literate participants, or its modified version created by Ertan et al. (MMSE-I) for uneducated participants], self-esteem (measured using the Rosenberg Self-Esteem Scale) and health-related social and functional disabilities measured using the World Health Organization Disability Assessment Schedule (WHODAS). For comparison, we used the Chi-squared test along with the Student's t-test for the proportions and means respectively.
Compared with the community controls, malnutrition survivors had a lower probability of attaining a high level of education (p < 0.001), of reporting a high academic performance (p = 0.014) or of having high self-esteem (p = 0.003). In addition, malnutrition survivors had an overall mean score in the cognitive test that was lower compared with the community controls [25.6 compared with 27.8, p = 0.001 (MMSE) and 22.8 compared with 26.3, p < 0.001(MMSE-I)] and a lower proportion of subjects with a normal result in this test (78.0% compared with 90.1%, p < 0.001). Lastly, in terms of health-related disabilities, unlike the community controls, malnutrition survivors had less social disability (p = 0.034), but no difference was observed as regards activities of daily living (p = 0.322).
SAM during childhood exposes survivors to low human capital as regards education, cognition and behaviour in adulthood. Policy-deciders seeking to promote economic growth and to address various psychological and medico-social disorders must take into consideration the fact that appropriate investment in child health as regards SAM is an essential means to achieve this.

The period from conception to 24 months of age is a crucial window for nutrition interventions. Personalized maternal counseling may improve childbirth outcomes, growth, and health. We assessed the effectiveness of facility-based personalized maternal nutrition counseling (from pregnancy to 18 months after birth) in improving child growth and health in rural Burkina Faso. We conducted a paired cluster randomized controlled trial in a rural district of Burkina Faso with 12 primary health centers (clusters). Healthcare providers in the intervention centers received patient-centered communication and nutrition counseling training. Pregnant women in the third trimester living in the center catchment areas and intending to stay for the next 2 years were prospectively included. We followed 2253 mother-child pairs quarterly until the child was aged 18 months. Women were interviewed about counseling experiences, dietary practices during pregnancy, and their child's feeding practices and morbidity history. Anthropometric measurements were taken at each visit using standardized methods. The primary outcomes were the cumulative incidence of wasting, and changes in child weight-for-height z-score (WHZ). Secondary outcomes were the women's prenatal dietary practices, early breastfeeding practices, exclusive breastfeeding, timely introduction of complementary food, child's feeding frequency and dietary diversity, children's mean birth weight, endpoint prevalence of stunting, and cumulative incidence of diarrhea, fever, and acute respiratory infection. All analyses were by intention-to-treat using mixed effects models. The intervention and control arms each included six health centers. Mothers in the intervention arm had a significantly higher exposure to counseling with 11.2% for breastfeeding techniques to 75.7% for counseling on exclusive breastfeeding. Mothers of infants below 6 months of age in the intervention arm were more likely to exclusively breastfeed (54.3% vs 42.3%; Difference of Proportion (DP) 12.8%; 95% CI: 2.1, 23.6; p = 0.020) as compared to the control arm. Between 6 and 18 months of age, more children in the intervention arm benefited from the required feeding frequency (68.8% vs 53.4%; DP 14.1%; 95% CI: 9.0, 19.2; p<0.001) and a larger proportion had a minimum dietary diversity (28.6% vs 22.0%; DP 5.9%; 95% CI: 2.7, 9.2; p<0.001). Birth weight of newborns in the intervention arm was on average 84.8 g (p = 0.037) larger compared to the control arm. However, we found no significant differences in child anthropometry or morbidity between study arms. Facility-based personalized maternal nutrition counseling was associated with an improved prenatal dietary practices, Infant and Young Child Feeding practices, and child birth weight. Complementary strategies are warranted to obtain meaningful impact on child growth and morbidity. This includes strategies to ensure good coverage of facility-based services and effective nutrition/care practices in early childhood.

It is well documented that treatment for severe acute malnutrition (SAM) is effective. However, little is known about the long-term outcomes for children treated for SAM. We sought to trace former SAM patients 11 to 30 years after their discharge from hospital, and to describe their longer-term survival and their growth to adulthood.
A total of 1,981 records of subjects admitted for SAM between 1988 and 2007 were taken from the archives of Lwiro hospital, in South Kivu, DRC. The median age on admission was 41 months. Between December 2017 and June 2018, we set about identifying these subjects (cases) in the health zones of Miti-Murhesa and Katana. For deceased subjects, the cause and year of death were collected. A Cox proportional hazards multivariate regression analysis was used to identify the death-related factors. For the cases seen, age- and gender-matched community controls were selected for a comparison of anthropometric indicators.
A total of 600 subjects were traced, and 201 subjects were deceased. Of the deceased subjects, 65·6% were under 10 years old at the time of their death. Of the deaths, 59·2% occurred within 5 years of discharge from hospital. The main causes of death were malaria (14·9%), kwashiorkor (13·9%), respiratory infections (10·4%), and diarrhoeal diseases (8·9%). The risk of death was higher in subjects with SAM, MAM combined with CM, and in male subjects, with HRs* of 1·83 (p = 0·043), 2.35 (p = 0·030) and 1.44 (p = 0·013) respectively. Compared with their controls, the cases had a low weight (-1·7 kg, p = 0·001), short height [sitting (-1·3 cm, p = 0·006) and standing (-1·7 cm, p = 0·003)], short legs (-1·6 cm, p = 0·002), and a small mid-upper arm circumference (-3·2mm, p = 0·051). There was no difference in terms of BMI, thoracic length, or head and thoracic circumference between the two groups.
SAM during childhood has lasting negative effects on growth to adulthood. In addition, these adults have characteristics that may place them at risk of chronic non-communicable diseases later in life.

Magnitude of low birthweight in malaria endemic settings of Nanoro, rural Burkina Faso: a secondary data analysis
2021
Low birthweight (LBW) is a worldwide problem that particularly affects developing countries. However, limited information is available on its magnitude in rural area of Burkina Faso. This study aimed to estimate the prevalence of low birthweight and to identify its associated factors in Nanoro health district. A secondary analysis of data collected during a cross-sectional survey was conducted to assess the prevalence of low birthweight in Nanoro health and demographic surveillance system area (HDSS). Maternal characteristics extracted from antenatal care books or by interview, completed by malaria diagnosis were examined through a multi-level logistic regression to estimate odd-ratios of association with low birthweight. Significance level was set at 5%. Of the 291 neonates examined, the prevalence of low birthweight was 12%. After adjustment for socio-demographic, obstetric and malaria prevention variables, being primigravid (OR = 8.84, [95% CI: 3.72–21.01]), or multigravid with history of stillbirth (OR = 5.03, [95% CI: 1.54–16.40]), as well as the lack of long-lasting insecticide treated bed net use by the mother the night preceding the admission for delivery (OR = 2.5, [95% CI: 1.1–5.9]) were significantly associated with neonate low birthweight. The number of antenatal visits however did not confer any direct benefit on birthweight status within this study area. The prevalence of low birthweight was high in the study area and represents an important public health problem in Burkina Faso. In light of these results, a redefinition of the content of the antenatal care package is needed.

Background
The studies on the use and performance of the Mid-Upper Arm Circumference for age (MUACZ) for the diagnosis of severe acute malnutrition (SAM) are still rare. Our study aimed to analyze the performance of MUACZ for diagnosis of SAM in South Kivu, eastern DR Congo.
Methods
We analyzed a database of children admitted from 1987 to 2008 for management of SAM in the east of the DRC. Anthropometric indicators (z-score) were calculated and classified according to the standards of the World Health Organization (WHO). To evaluate the performance of MUACZ using the combination of weight-for-height (WHZ) and Mid-Upper Arm Circumference (MUAC) as the reference, we calculated sensitivity, specificity, positive and negative predictive values (PPV and NPV) overall. Subsequently, we stratified the results by age category, presence or absence of stunting, and presence or absence of edema.
Results
Of the 9969 children aged 6 to 59 months selected, 30.2% had nutritional edema, 70.1% had stunting. Of all cases of SAM (identified by at least one of the WHZ, MUAC, or MUACZ indicators), MUACZ alone identified 85% of them, surpassing other criteria such as MUAC (58%) and WHZ (45%). The MUACZ-WHZ combination identified 97%, surpassing the MUAC-WHZ combination (76%). In the presence of edema, MUACZ-WHZ identified 99%, while MUAC-WHZ identified only 72%. The proportions of SAM cases diagnosed by MUACZ increased according to age groups, with rates of 73% (6–11 months), 85% (12–23 months) and 91% (24–59 months). In the presence of stunting, the detection rates were 58% for MUAC alone, 44% for WHZ alone, 89% for MUACZ alone, 67% for the MUAC-WHZ combination, and 98% for the MUACZ-WHZ combination. MUACZ had a sensitivity of 80.7% (79.9–81.5), a specificity of 92.3% (91.8–92.8), a PPV of 71.5% (70.7–72.4) with a prior prevalence was 19,3% defined by the reference, and an NPV of 95.2% (94.8–95.7). Sensitivity increased in the presence of edema [90.1% (88.9–91.1)], stunting [84.7% (83.8–85.5)] and in children over 12 months [83.6% (82.2–84.9)].
Conclusion
The MUACZ was performing well in our region. In a context of high prevalence of stunting and kwashiorkor, MUACZ appears to be a more reliable indicator than MUAC alone. Moreover, the MUACZ-WHZ combination also seems to outperform the MUAC-WHZ combination. These results highlight the MUACZ potential, as well as its combination with WHZ, in enhancing screening of SAM in similar contexts.

Background
The objectives of the study reported in this paper were: (a) to score the coverage of core NCD population-based interventions and individual services in Mauritius; (b) to analyse and score the presence of 15 common health system challenges that impede delivery of core NCD interventions and services in Mauritius; and (c) to provide policy recommendations for Mauritius to address health system barriers to delivery of NCD interventions and services.
Methods
The Mauritius country assessment applied the guidelines developed by the World Health Organization Regional Office for Europe for systematically scoring coverage of NCD interventions and assessing health system challenges for improving NCD outcomes. The assessment used qualitative research design approach.
Results
Of the 24 core population-based interventions for addressing key NCD risk factors, 16.7% were rated extensive, 37.5% moderate and 45.8% limited. Three (20%), 8 (53%) and 4 (27%) of the 15 individual/personal CVD, diabetes and cancer services were rated extensive, moderate and limited respectively. The top five health system challenges hampering scale-up of coverage of population-based NCD interventions in Mauritius were inadequate interagency cooperation; limited application of explicit priority setting approaches; inadequate change management; sub-optimal distribution and mix human resources; insufficient population empowerment; and insufficient political commitment. The top five challenges had average scores of between 3.1 (interagency cooperation) and 2.4 (distribution and mix of human resources).
The top five health system challenges constraining expansion in coverage of individual NCD services were limited integration of evidence into practice; limited use of explicit priority-setting approaches; inadequate application of information and technology solutions; insufficient population empowerment; and sub-optimal distribution and mix of human resources. The top five challenges for individual interventions had mean scores varying between 2.6 (integration of evidence into practice) and 1.7 (distribution and mix of human resources).
Conclusions
Mauritius needs to increase its domestic general government investments into the national health system and requisite multi-sectoral action to address the priority health system challenges with a view of bridging the existing gaps in coverage of NCD population-based interventions and individual services.

Background
Exposure during pregnancy to malaria and sexually-transmitted infections is associated with adverse birth outcomes including low birth weight (LBW). This study aimed at assessing if the adjunction of two doses of azithromycin to sulfadoxine-pyrimethamine for the intermittent preventive treatment of malaria in pregnancy can reduce LBW.
Methods
A two parallel-groups, open-label randomized controlled trial involving pregnant women (16 to 35 years of age and 12 to 24 weeks of gestation as confirmed by last menstrual period or fundal height) was conducted in rural Burkina Faso. Women were assigned in a 1:1 ratio either to use azithromycin (1 g daily for 2 days) during the second and third trimesters of pregnancy plus monthly sulfadoxine-pyrimethamine (1500/75 mg) (SPAZ) (intervention) or to continue using a monthly sulfadoxine-pyrimethamine (1500/75 mg) (SP) (control). Primary outcome was a LBW (birth weight measured within 24 h after birth < 2500 g). Secondary outcomes including stillbirth, preterm birth or miscarriage are reported together with safety data.
Results
A total of 992 pregnant women underwent randomization (496 per group) and 898 (90.5%) valid birth weights were available (450 in SPAZ and 448 in SP). LBW incidence was 8.7% (39/450) in SPAZ and 9.4% (42/448) in controls (p-value = 0.79). Compared with controls, pregnant women with SPAZ showed a risk ratio (RR) of 1.16 (95% confidence interval (CI 0.64–2.08]) for preterm births, 0.75 (95% CI 0.17–3.35) for miscarriage and 0.64 (95% CI 0.25–1.64) for stillbirths. No treatment-related serious adverse events (SAEs) have been observed, and there was no significant difference in the number of SAEs (13.5% [67/496] in SPAZ, 16.7% [83/496] in SP, p-value = 0.18) or AEs (17.1% [85/496] in SPAZ, 18.8% [93/496] in SP, p-value = 0.56).
Conclusion
Adequate prevention regimen with monthly sulfadoxine-pyrimethamine given to all pregnant women has been proved to reduce the risk of LBW in malaria endemic areas. Adding azithromycin to the regimen does not offer further benefits, as far as women receive a malaria prevention regimen early enough during pregnancy.

Background
Little is known about the use of mid-upper arm circumference for age (MUACZ) for diagnosing of severe acute malnutrition (SAM) and its correlation with WHZ (weight-for-height Z-score) in an area endemic for severe acute malnutrition (SAM) and with a high prevalence of kwashiorkor. Our study aims to analyze the concordance between the diagnostic criteria of SAM in a region presenting these characteristics.
Methods
We analyzed a database of children admitted from 1987 to 2008 for the management of SAM in Eastern Democratic Republic of Congo. Anthropometric indicators (z-score) were calculated and classified into 3 categories according to WHO standards. Cohen’s kappa coefficient (κ) was calculated to assess the concordance between these indicators.
Results
Out of the 9969 selected children aged 6 to 59 months, 30.2% had nutritional edema, 70.1% had a height-for-age (HAZ) z-score <-2, 11.5% WHZ<-3 z-score, 14.9% had a MUAC < 115 mm and 21.8% had a MUACZ <-3 z-score. With the classic combination WHZ and MUAC, 36% of children with SAM had both criteria at the same time and MUAC alone being the indicator that recruited more children with SAM (77%) compared with 65% with WHZ only. By replacing MUAC with MUACZ, 34% of SAM children fulfilled both criteria, WHZ and MUACZ. MUACZ alone recruited more children with SAM (88%) compared with 46% with WHZ alone. Considering these three indicators together, MUACZ remained the indicator that recruited more children with SAM (85%). WHZ and MUAC showed a moderate agreement [ κ (95% CI) = 0.408(0.392–0.424)], WHZ and MUACZ a weak agreement [ κ (95% CI) = 0.363(0.347–0.379)] and MUAC and MUACZ a good agreement [ κ (95% CI) = 0.604 (0.590–0.618)].
Conclusion
Adjusting MUAC according to age improves its effectiveness in identifying severe acute malnutrition. With low concordance, MUAC and WHZ remain complementary in our context. MUACZ proves to be crucial, especially in the presence of kwashiorkor and chronic malnutrition, becoming a valuable tool for assessing severe acute malnutrition in our context.

2019
Background
In the Democratic Republic of the Congo (DRC), more than 93% of users must pay out of pocket for care. Despite the risk of catastrophic expenditures (CE), 94% of births in Lubumbashi are attended by skilled personnel. We aimed to identify risk factors for CE associated with obstetric and neonatal care in this setting, to document coping mechanisms employed by households to pay the price of care, and to identify consequences of CE on households.
Methods
We used mixed methods and conducted both a cross-sectional study and a phenomenological study of women who delivered at 92 health care facilities in all 11 health zones of Lubumbashi. In April and May 2015 we followed 1,627 women and collected data on their health care and household expenses to determine whether they experienced CE, defined as payments that reached or exceeded 40% of a household’s capacity to pay. Two months after discharge, we conducted semi-structured interviews with 58 women at their homes to assess the consequences of CE.
Results
In all, 261 of 1,627 (16.0%) women experienced CE. Whether a woman or her infant experienced complications was an important contributor to her risk of CE; poverty, younger age, being unmarried, and delivering in a parastatal facility or with more highly trained personnel also increased risk. Among a subset of women with CE interviewed 2 months after discharge, those who were in debt or who had lost their trading income or goods were unable to pay their rent, their children’s school fees, or were obliged to reduce food consumption in the household; some had become victims of mistreatment such as verbal abuse, disputes with in-laws, denial of paternity, abandonment by partners, financial deprivation, even divorce.
Conclusions
We found a higher proportion of CE than previously reported in the DRC or in other urban settings in Africa. We suggest that the government and funders in DRC support initiatives to put in place mutual-aid health risk pools and health insurance and introduce and institutionalize free maternal and infant care. We further suggest that the government ensure decent and regular payment of providers and improve the financing and functioning of health care facilities to improve the quality of care and alleviate the burden on users.

Diarrhea is one of the leading causes of childhood morbidity and mortality. Hospitalization for diarrhea can pose a significant burden to health systems and households. The objective of this study was to estimate the economic burden attributable to hospitalization for diarrhea among children less than five years old in Rwanda. These data can be used by decision-makers to assess the impact of interventions that reduce diarrhea morbidity, including rotavirus vaccine introduction.
This was a prospective costing study where medical records and hospital bills for children admitted with diarrhea at three hospitals were collected to estimate resource use and costs. Hospital length of stay was calculated from medical records. Costs incurred during the hospitalization were abstracted from the hospital bills. Interviews with the child's caregivers provided data to estimate household costs which included transport costs and lost income. The portion of medical costs borne by insurance and household were reported separately. Annual economic burden before and after rotavirus vaccine introduction was estimated by multiplying the reported number of diarrhea hospitalizations in public health centers and district hospitals by the estimated economic burden per hospitalization. All costs are presented in 2014 US$.
Costs for 203 children were analyzed. Approximately 93% of the children had health insurance coverage. Average hospital length of stay was 5.3 ± 3.9 days. Average medical costs for each child for the illness resulting in a hospitalization were $44.22 ± $23.74 and the total economic burden was $101, of which 65% was borne by the household. For households in the lowest income quintile, the household costs were 110% of their monthly income. The annual economic burden to Rwanda attributable to diarrhea hospitalizations ranged from $1.3 million to $1.7 million before rotavirus vaccine introduction.
Households often bear the largest share of the economic burden attributable to diarrhea hospitalization and the burden can be substantial, especially for households in the lowest income quintile.
