Association Between Interpregnancy Interval and Risk of Preterm Birth and Its Modification by Folate Intake: The Japan Environment and Children's Study.

BACKGROUND: Both short and long interpregnancy intervals (IPIs) have been associated with risk of preterm birth, but the evidence is limited in Asians. It is also uncertain whether the association is modified by dietary folate intake or folic acid supplementation during pregnancy. Thus, we examined associations between IPI and risk of preterm birth and effect modification of those associations by dietary intake of folate and supplementation with folic acid on the basis of a nationwide birth cohort study. METHODS: Among 103,062 pregnancies registered in the Japan Environment and Children's Study, 55,203 singleton live-birth pregnancies were included in the analysis. We calculated IPI using birth date, gestational age at birth of offspring, and birth data of the latest offspring. Odds ratios (ORs) and 95% confidence intervals (CIs) of the risk of preterm birth were estimated according to IPI categories. RESULTS: Both <6-month and ≥120-month IPIs were associated with an increased risk of preterm birth, compared with an 18-23-month IPI. The multivariable ORs were 1.63 (95% CI, 1.30-2.04) for <6-month and 1.41 (95% CI, 1.11-1.79) for ≥120-month IPIs. These associations were confined to women with inadequate intake of dietary folate and folic acid supplementation during pregnancy. Multivariable ORs were 1.76 (95% CI, 1.35-2.29) for <6-month IPI and 1.65 (95% CI, 1.24-2.19) for ≥120-month IPI. CONCLUSION: Both <6-month and ≥120-month IPIs were associated with an increased risk of preterm birth. These higher risks were confined to women with inadequate intake of dietary folate and folic acid supplementation during pregnancy.

Short interpregnancy interval and its predictors in Ethiopia: implications for policy and practice.

Introduction: interpregnancy interval (IPI) is the time elapsed between the birth of one live child and the conception of subsequent pregnancies. Several studies in Ethiopia indicated a high prevalence of a short interbirth interval - a proxy indicator of IPI. However, these studies were prone to selection bias as they did not include women who did not go on to have another pregnancy. Therefore, this study estimated the incidence of short IPI (< 24 months) and its risk factors among women who had at least one child in Ethiopia. Methods: we used a retrospective analysis of a cross-sectional study from the nationally representative Ethiopian Mini Demographic and Health Survey (EMDHS) conducted in 2019. The event was defined as the conception of the subsequent pregnancy within 24 months following the last child. A weighted Cox Proportional Hazard model was used to estimate the adjusted hazard ratios (aHR) and 95% confidence intervals (CIs). Results: the incidence of short IPI was 6%. Rural residence, being young age, low educational attainment, having the last child died and having female last birth were the risk factors for short IPI. However, having higher parity, attending Antenatal Care (ANC) visits, being delivered at a health facility, and receiving Postnatal Care (PNC) visits were the protective factors for short IPI. Conclusion: the incidence of short IPI in Ethiopia was considerable. Sociodemographic and health service-related factors determine the short IPI. Hence, considering the immediate and long-term health and socioeconomic consequences of short IPI, the Ethiopian government should implement holistic and multisectoral interventions.

Iron status in mid-pregnancy and associations with interpregnancy interval, hormonal contraceptives, dietary factors and supplement use.

Adequate iron supply in pregnancy is important for both the woman and the fetus, but iron status is often assessed late in first trimester, if assessed at all. Therefore, identification of factors associated with iron status is important to target vulnerable groups with increased risk of deficiency. Our objectives were to (1) describe iron status in mid-pregnancy and (2) identify sociodemographic and lifestyle predictors of pregnancy iron status. This cross-sectional study uses data from The Norwegian Mother, Father and Child Cohort Study (collected 2002-2008) and The Medical Birth Registry of Norway. Iron status was measured as non-fasting plasma ferritin (P-Fe) and transferrin in gestational week (GW) 18 (n 2990), and by lowest reported Hb in GW 0-30 (n 39 322). We explored predictors of iron status with elastic net, linear and log-binomial regression models. Median P-Fe was 33 µg/l, and 14 % had depleted iron stores (P-Fe <15 µg/l). P-Fe below 30 µg/l was associated with reduced Hb. We identified eleven predictors, with interpregnancy interval (IPI) and parity among the most important. Depleted iron stores was more common among women with IPI < 6 months (56 %) and 6-11 months (33 %) than among those with IPI 24-59 months (19 %) and among nulliparous women (5 %). Positively associated factors with iron status included hormonal contraceptives, age, BMI, smoking, meat consumption and multi-supplement use. Our results highlight the importance of ferritin measurements in women of childbearing age, especially among women not using hormonal contraceptives and women with previous and recent childbirths.

Trends for Neonatal Deaths in Nepal (2001-2016) to Project Progress Towards the SDG Target in 2030, and Risk Factor Analyses to Focus Action.

INTRODUCTION: Nepal has made considerable progress on improving child survival during the Millennium Development Goal period, however, further progress will require accelerated reduction in neonatal mortality. Neonatal survival is one of the priorities for Sustainable Development Goals 2030. This paper examines the trends, equity gaps and factors associated with neonatal mortality between 2001 and 2016 to assess the likelihood of Every Newborn Action Plan (ENAP) target being reached in Nepal by 2030. METHODS: This study used data from the 2001, 2006, 2011 and 2016 Nepal Demographic and Health Surveys. We examined neonatal mortality rate (NMR) across the socioeconomic strata and the annual rate of reduction (ARR) between 2001 and 2016. We assessed association of socio-demographic, maternal, obstetric and neonatal factors associated with neonatal mortality. Based on the ARR among the wealth quintile between 2001 and 2016, we made projection of NMR to achieve the ENAP target. Using the Lorenz curve, we calculated the inequity distribution among the wealth quintiles between 2001 and 2016. RESULTS: In NDHS of 2001, 2006, 2011 and 2016, a total of 8400, 8600, 13,485 and 13,089 women were interviewed respectively. There were significant disparities between wealth quintiles that widened over the 15 years. The ARR for NMR declined with an average of 4.0% between 2001 and 2016. Multivariate analysis of the 2016 data showed that women who had not been vaccinated against tetanus had the highest risk of neonatal mortality (adjusted odds ratio [AOR] 3.38; 95% confidence interval [CI] 1.20-9.55), followed by women who had no education (AOR 1.87; 95% CI 1.62-2.16). Further factors significantly associated with neonatal mortality were the mother giving birth before the age of 20 (AOR 1.76; CI 95% 1.17-2.59), household air pollution (AOR 1.37; CI 95% 1.59-1.62), belonging to a poorest quintile (AOR 1.37; CI 95% 1.21-1.54), residing in a rural area (AOR 1.28; CI 95% 1.13-1.44), and having no toilet at home (AOR 1.21; CI 95% 1.06-1.40). If the trend of neonatal mortality rate of 2016 continues, it is projected that the poorest family will reach the ENAP target in 2067. CONCLUSIONS: Although neonatal mortality is declining in Nepal, if the current trend continues it will take another 50 years for families in the poorest group to attain the 2030 ENAP target. There are different factors associated with neonatal mortality, reducing the disparities for maternal and neonatal care will reduce mortality among the poorest families.

Improving autism perinatal risk factors: A systematic review.

BACKGROUND: Current understanding of the etiology of autism is based on the interaction of multiple genes with each other and with environmental factors, leading to a neurodevelopmental process that results in the expression of autism spectrum disorder (ASD) in the child. This suggests that it might be possible to strengthen resilience to environmental stressors during the perinatal period to improve outcomes and possibly prevent the development of ASD. METHODS: We searched the MEDLINE database for multiple perinatal factors associated with the development of ASD published between January 1, 2005 and July 1, 2018. The search terms used were "autism" crossed with either "perinatal," "prenatal," "gestational," or "pregnancy," and crossed again with each perinatal risk factor highlighted in this review including topics on parental health, infections, medications, and environmental stressors. We then searched interventions that may improve neurodevelopmental outcome before and during pregnancy, including supplements, breastfeeding, and postpartum stress reduction. We identified recent or unique metanalyses and systematic reviews of the identified focus and on randomized controlled trials and summarized these using the most recent and comprehensive reviews. RESULTS: Folate, omega-3, vitamin D3, environmental toxin avoidance, correcting deficiencies, immune boosting, and prolonged breast feeding are all reported to be linked to the possible reduction of adverse pregnancy outcomes including ASD. CONCLUSIONS: Studies of individual components for improving pregnancy outcomes and several uncontrolled preconception to infancy medical practices suggest that multiple interventions might improve the outcomes of pregnancies where there is risk for developing ASD.

The role of traditional contraceptive methods in family planning among women attending primary health care centers in Kano.

Background: Traditional contraceptive methods (TCMs) have been used by our ancestors for a long time in child spacing before the advent of the modern contraceptive methods but even with the introduction of the modern methods some women prefer and are still using TCMs. Aim: The aim of this study was to assess the utilization of traditional contraceptives in child spacing and its association with family size among women of child-bearing age attending primary healthcare centers in Kano. Materials and Methods: This was a cross-sectional study among 400 women attending primary healthcare centers in Kano. Their sociodemographic characteristics, number of children, knowledge, and use of traditional contraceptives were recorded on a pretested questionnaire. Results: The mean age ± standard deviation (SD) was 29.1 ± 6.22 years. The mean number of children (±SD) was 3.9 ± 2.27. A total number of 280 (70.0%) participants knew about TCMs, but only 147 (36.8%) used these methods and among those that used TCMs, herbal medicine was the most used method (n = 67, 45.6%). There was no statistically significant difference between the mean number of children of the respondents who used traditional contraceptives and those who did not (t = 0.382, df = 398, P = 0.703, 95% confidence interval:-0.374-0.555). Educational status was significantly associated with the use of traditional contraceptives (χ2 = 8.327, P = 0.005). Conclusion: There was more knowledge of traditional than modern contraceptive methods. Herbal medicine was the most commonly used method. There was poor utilization of the modern contraceptive methods and fair utilization of the TCMs. The study showed no clear benefit of traditional contraceptive usage over its nonuse in reducing family size.

RésuméContexte: Les méthodes contraceptives traditionnelles (MTC) ont longtemps été utilisées par nos ancêtres dans l'espacement des naissances avant l'avènement des méthodes contraceptives modernes, mais même avec l'introduction des méthodes modernes certaines femmes préfèrent et utilisent encore les MTC. But: Le but de cette étude est d'évaluer l'utilisation des contraceptifs traditionnels dans l'espacement des naissances et son association avec la taille de la famille parmi les femmes en âge de procréer fréquentant les centres de soins de santé primaires à Kano. Matériels et méthodes: Il s'agissait d'une étude transversale parmi 400 femmes fréquentant les centres de soins de santé primaires à Kano. Leurs caractéristiques sociodémographiques, le nombre d'enfants, la connaissance et l'utilisation de les contraceptifs traditionnels ont été enregistrés sur un questionnaire pré-testé. Résultats: L'âge moyen ± écart type (ET) était de 29,1 ± 6,22 ans. Le nombre moyen d'enfants (± écart-type) était de 3,9 ± 2,27. Un chiffre de 280 (70,0%) connaissait les MTC, mais seulement 147 (36,8%) utilisaient ces méthodes et parmi celles qui utilisaient des MTC, la phytothérapie était la méthode la plus utilisée (n = 67, 45,6%). Il n'y avait pas de différence statistiquement significative entre le nombre moyen d'enfants des répondants qui ont utilisé des contraceptifs traditionnels et ceux qui ne l'ont pas fait (t = 0,382, df = 398, P = 0,703, Intervalle de confiance de 95%: -0,374-0,555). Le statut éducatif était significativement associé à l'utilisation des contraceptifs traditionnels (χ2 = 8,327, P = 0,005). Conclusion: Il y avait plus de connaissance des méthodes contraceptives traditionnelles que modernes. La phytothérapie était la plus méthode couramment utilisée. Les méthodes modernes de contraception et l'utilisation équitable des MTC ont été mal utilisées. L'étude a montré pas de bénéfice clair de l'utilisation traditionnelle de la contraception par rapport à sa non-utilisation pour réduire la taille de la famille.

Pre-lacteal feeding practice and associated factors among mothers having children less than two years of age in Aksum town, Tigray, Ethiopia, 2017: a cross-sectional study.

BACKGROUND: Pre-lacteal feeding has continued as a deep-rooted nutritional malpractice in developing countries. Pre-lacteal feeding is a barrier to the implementation of optimal breastfeeding practices and increases the risk of neonatal early-life diseases and mortality. Therefore, the aim of this study was to assess pre-lacteal feeding practice and associated factors among mothers having children less than 2 years of age in Aksum town, central Tigray, Ethiopia. METHODS: A community-based cross-sectional study was conducted to interview 477 mother-child pairs by systematic random sampling technique. Data were collected through interviewer-administered semi-structured questionnaires. Data were coded, entered, cleaned and edited using EPIDATA version 3.1 and export to SPSS Version 22.0 for analysis. To identify the significant variables binary logistic regression were employed. Variables with p-value < 0.05 at 95% CI in multivariate logistic regression were considered statistically significant. RESULT: The prevalence of pre-lacteal feeding in Aksum town was 10.1% (95% CI: 7.3%, 13%). Mothers with no previous birth (AOR: 2.93(95% CI:1.21,7.09)), birth spacing less than 24 (AOR: 2.88(95% CI: 1.15,7.25)), colostrum discarding (AOR: 6.72 (95% CI: 2.49,18.12)), less than four anti natal care follow up (AOR: 10.55 (95% CI: 4.78,23.40)), those who underwent cesarean section (AOR: 4.38 (95% CI:1.72,11.12)) and maternal believe on purported advantage of pre-lacteal feeding (AOR: 3.36 (95%CI: 1.62,6.96)) were more likely to practice pre-lacteal feeding to their infants. CONCLUSIONS: Pre-lacteal feeding is still practiced in the study area. Childbirth spacing, colostrum discarding, antenatal Care follow up, maternal belief in pre-lacteal feeding was contributing factors for practicing of pre-lacteal feeding. Coordination and sustaining the existing strategies and approaches are recommended to give emphasis on the nutritional value of colostrum and anti-natal care follow up.

Facilitators and Barriers to Healthy Pregnancy Spacing among Medicaid Beneficiaries: Findings from the National Strong Start Initiative.

BACKGROUND: Closely spaced, unintended pregnancies are common among Medicaid beneficiaries and create avoidable risks for women and infants, including preterm birth. The Strong Start for Mothers and Newborns Initiative, a program of the Center for Medicare and Medicaid Innovation, intended to prevent preterm birth through psychosocially based enhanced prenatal care in maternity care homes, group prenatal care, and birth centers. Comprehensive care offers the opportunity for education and family planning to promote healthy pregnancy spacing. METHODS: As of March 30, 2016, there were 42,138 women enrolled in Strong Start and 23,377 women had given birth. Individual-level data were collected through three participant survey instruments and a medical chart review, and approximately one-half of women who had delivered (n = 10,374) had nonmissing responses on a postpartum survey that asked about postpartum family planning. Qualitative case studies were conducted annually for the first 3 years of the program and included 629 interviews with staff and 122 focus groups with 887 Strong Start participants. RESULTS: Most programs tried to promote healthy pregnancy spacing through family planning education and provision with some success. Group care sites in particular established protocols for patient-centered family planning education and decision making. Despite program efforts, however, barriers to uptake remained. These included state and institutional policies, provider knowledge and bias, lack of protocols for timing and content of education, and participant issues such as transportation or cultural preferences. CONCLUSIONS: The Strong Start initiative introduced a number of successful strategies for increasing women's knowledge regarding healthy pregnancy spacing and access to family planning. Multiple barriers can impact postpartum Medicaid participants' capacity to plan and space pregnancies, and addressing such issues holistically is an important strategy for facilitating healthy interpregnancy intervals.

Program considerations for integration of nutrition and family planning: Beliefs around maternal diet and breastfeeding within the context of the nutrition transition in Egypt.

In Egypt, rising maternal overweight and obesity is consistent with the transition to westernized diets and a growing reliance on energy-dense, low nutrient foods. Although the first 1,000 days of life are the focus of many programmes designed to prevent many forms of malnutrition, little attention has been paid to maternal dietary practices and weight gain during pregnancy. This study used in-depth interviews with pregnant women (N = 40), lactating women (N = 40), and nonlactating women (N = 40) to gain an understanding of behaviours, perceptions, and cultural beliefs in relation to maternal dietary intake during pregnancy, lactation, and nonlactation; weight gain during pregnancy; birth spacing; and family planning. Study findings reveal that food choice was driven by affordability, favoured foods, or foods considered appropriate for a specific life stage (pregnant, lactating, and nonlactating). Knowledge of weight gain during pregnancy is limited, especially with regards to excessive weight gain during pregnancy. Diet is often modified during lactation to support breast milk production, and a normal diet resumed when breastfeeding ceases. Within the context of breastfeeding, the lactational amenorrhea method provides an opportunity to improve exclusive breastfeeding practices, maternal diet during lactation, and the transition to other family planning methods by 6 months postpartum. Health care providers should discuss limiting maternal consumption of low nutrient foods such as junk foods, soda, and teas during pregnancy and postpartum. Dietary counselling should accompany information on appropriate weight gain during pregnancy and exercise to prevent excessive weight gain, in the context of the nutrition transition.

Evaluating the comparative effectiveness of different demand side interventions to increase maternal health service utilization and practice of birth spacing in South Kivu, Democratic Republic of Congo: an innovative, mixed methods approach.

BACKGROUND: In this protocol we describe a mixed methods study in the province of South Kivu, Democratic Republic of Congo evaluating the effectiveness of different demand side strategies to increase maternal health service utilization and the practice of birth spacing. Conditional service subsidization, conditional cash transfers and non-monetary incentives aim to encourage women to use maternal health services and practice birth spacing in two different health districts. Our methodology will comparatively evaluate the effectiveness of different approaches against each other and no intervention. METHODS/DESIGN: This study comprises four main research activities: 1) Formative qualitative research to determine feasibility of planned activities and inform development of the quantitative survey; 2) A community-based, longitudinal survey; 3) A retrospective review of health facility records; 4) Qualitative exploration of intervention acceptability and emergent themes through in-depth interviews with program participants, non-participants, their partners and health providers. Female community health workers are engaged as core members of the research team, working in tandem with female survey teams to identify women in the community who meet eligibility criteria. Female community health workers also act as key informants and community entry points during methods design and qualitative exploration. Main study outcomes are completion of antenatal care, institutional delivery, practice of birth spacing, family planning uptake and intervention acceptability in the communities. Qualitative methods also explore decision making around maternal health service use, fertility preference and perceptions of family planning. DISCUSSION: The innovative mixed methods design allows quantitative data to inform the relationships and phenomena to be explored in qualitative collection. In turn, qualitative findings will be triangulated with quantitative findings. Inspired by the principles of grounded theory, qualitative analysis will begin while data collection is ongoing. This "conversation" between quantitative and qualitative data will result in a more holistic, context-specific exploration and understanding of research topics, including the mechanisms through which the interventions are or are not effective. In addition, engagement of female community health workers as core members of the research team roots research methods in the realities of the community and provides teams with key informants who are simultaneously implicated in the health system, community and target population.

Short interpregnancy intervals, maternal folate levels, and infants born small for gestational age: a preliminary study in a Canadian supplement-using population.

Short interpregnancy intervals (SIPI) have been associated with increased risks for adverse neonatal outcomes including preterm delivery and infants small for gestational age (SGA). It has been suggested that mechanistically, adverse neonatal outcomes after SIPI arise due to insufficient recovery of depleted maternal folate levels prior to the second pregnancy. However, empirical data are lacking regarding physiological folate levels in pregnant women with SIPI and relationships between quantified physiological folate levels and outcomes like SGA. Therefore, we sought to test 2 hypotheses, specifically that compared with controls women with SIPI would: (i) have lower red blood cell folate (RBCF) levels and (ii) be more likely to have SGA infants (defined as <10th percentile). Using data collected in British Columbia, Canada, for a larger study on perinatal psychopathology, we documented supplementation use and compared prenatal RBCF levels and proportion of SGA infants between women with SIPI (second child conceived ≤24 months after previous birth, n = 26) and matched controls (no previous pregnancies, or >24 months between pregnancies, n = 52). There were no significant differences in either mean RBCF levels (Welch's t test, p = 0.7) or proportion of SGA infants (Fisher's exact test, p = 0.7) between women with SIPI and matched controls. We report the first data about RBCF levels in the context of SIPI. If confirmed, our finding of no relationship between these variables in this population suggests that continued folic acid supplementation following an initial pregnancy mitigates folate depletion. We found no relationship between SIPI and SGA.

Preventing deaths due to the hypertensive disorders of pregnancy.

In this chapter, taking a life cycle and both civil society and medically oriented approach, we will discuss the contribution of the hypertensive disorders of pregnancy (HDPs) to maternal, perinatal and newborn mortality and morbidity. Here we review various interventions and approaches to preventing deaths due to HDPs and discuss effectiveness, resource needs and long-term sustainability of the different approaches. Societal approaches, addressing sustainable development goals (SDGs) 2.2 (malnutrition), 3.7 (access to sexual and reproductive care), 3.8 (universal health coverage) and 3c (health workforce strengthening), are required to achieve SDGs 3.1 (maternal survival), 3.2 (perinatal survival) and 3.4 (reduced impact of non-communicable diseases (NCDs)). Medical solutions require greater clarity around the classification of the HDPs, increased frequency of effective antenatal visits, mandatory responses to the HDPs when encountered, prompt provision of life-saving interventions and sustained surveillance for NCD risk for women with a history of the HDPs.

Engaging with community-based public and private mid-level providers for promoting the use of modern contraceptive methods in rural Pakistan: results from two innovative birth spacing interventions.

BACKGROUND: Family planning (FP) interventions aimed at reducing population growth have negligible during the last two decades in Pakistan. Innovative FP interventions that help reduce the growing population burden are the need of the hour. Marie Stopes Society--Pakistan implemented an operational research project--'Evidence for Innovating to Save Lives', to explore effective and viable intervention models that can promote healthy timing and spacing of pregnancy in rural and under-served communities of Sindh, Punjab and Khyber Pakhtunkhwa provinces of Pakistan. METHODS: We conducted a quasi-experimental (pre- and post-intervention with control arm) study to assess the effectiveness of each of the two intervention models, (1) Suraj model (meaning 'Sun' in English), which uses social franchises (SF) along with a demand-side financing (DSF) approach using free vouchers, and (2) Community Midwife (CMW) model, in promoting the use of modern contraceptive methods compared to respective controls. Baseline and endline cross-sectional household surveys were conducted, 24 months apart, by recruiting 5566 and 6316 married women of reproductive age (MWRA) respectively. We used Stata version 8 to report the net effect of interventions on outcome indicators using difference-in-differences analysis. Multivariate Cox proportional hazard regression analysis was used to assess the net effect of the intervention on current contraceptive use, keeping time constant and adjusting for other variables in the model. RESULTS: The Suraj model was effective in significantly increasing awareness about FP methods among MWRA by 14% percentage points, current contraceptive use by 5% percentage points and long term modern method--intrauterine device (IUD) use by 6% percentage points. The CMW model significantly increased contraceptive awareness by 28% percentage points, ever use of contraceptives by 7% percentage points and, IUD use by 3% percentage points. Additionally the Suraj intervention led to a 35% greater prevalence (prevalence ratio: 1.35, 95% CI: 1.22-1.50) of contraceptive use among MWRA. CONCLUSION: Suraj intervention highlights the importance of embedding subsidized FP services within the communities of the beneficiaries. The outcomes of the CMW intervention also improved the use of long-term contraceptives. These findings indicate the necessity of designing and implementing FP initiatives involving local mid-level providers to expand contraceptive coverage in under-served areas.

Optimizing Subsequent Pregnancy Outcomes for Women with a Prior Preterm Birth.

Women with a prior preterm birth are at increased risk of recurrent preterm delivery in a subsequent pregnancy. Interventions during the preconception and prenatal periods can decrease this risk. Review of the circumstances of the prior delivery can elucidate whether delivery was spontaneous or indicated, anticipate recurrence risk, and guide management in a subsequent pregnancy. Preconception interventions for women with prior preterm birth should include cessation of tobacco and substance abuse, control of underlying maternal comorbidities, and encouraging a healthy body mass index. Effective contraception, including use of long-acting reversible methods, should be encouraged to facilitate planned pregnancies with optimal interpregnancy intervals. Interventions during prenatal care include screening and treatment of infections, nutritional supplementation, and enhanced prenatal care. Women with prior spontaneous preterm birth may benefit from progesterone supplementation and serial cervical length screening, while women with prior indicated preterm birth may benefit from daily aspirin.

The Effect of Integrating Family Planning with a Maternal and Newborn Health Program on Postpartum Contraceptive Use and Optimal Birth Spacing in Rural Bangladesh.

Meeting postpartum contraceptive need remains a major challenge in developing countries, where the majority of women deliver at home. Using a quasi-experimental trial design, we examine the effect of integrating family planning (FP) with a community-based maternal and newborn health (MNH) program on improving postpartum contraceptive use and reducing short birth intervals <24 months. In this two-arm trial, community health workers (CHWs) provided integrated FP counseling and services during home visits along with their outreach MNH activities in the intervention arm, but provided only MNH services in the control arm. The contraceptive prevalence rate (CPR) in the intervention arm was 15 percent higher than in the control arm at 12 months, and the difference in CPRs remained statistically significant throughout the 24 months of observation. The short birth interval of less than 24 months was significantly lower in the intervention arm. The study demonstrates that it is feasible and effective to integrate FP services into a community-based MNH care program for improving postpartum contraceptive use and lengthening birth intervals.

What is new in interpregnancy interval and pregnancy outcome? Best articles from the past year.

This month we focus on current research in pregnancy spacing. Dr. Campbell discusses five recent publications, and each is concluded with a "bottom line" that is the take-home message. The complete reference for each can be found in on this page, along with direct links to the abstracts.

Determinants of health facility utilization for childbirth in rural western Kenya: cross-sectional study.

BACKGROUND: Skilled attendance at delivery is recognized as one of the most important factors in preventing maternal death. However, more than 50% of births in Kenya still occur in non-institutional locations supported by family members and/or traditional birth attendants (TBAs). To improve this situation, a study of the determinants of facility delivery, including individual, family and community factors, was necessary to consider effective intervention in Kenya. METHODS: This study was conducted to identify the factors which influence the place of delivery in rural western Kenya, and to recommend ways to improve women's access to skilled attendants at delivery. A community-based cross-sectional survey was carried out from August to September 2011 in all 64 sub-locations which were covered by community health workers (CHWs). An interviewer-administered questionnaire on seventeen comprehensive variables was administered to 2,560 women who had children aged 12-24 months. RESULTS: The response rate was 79% (n = 2,026). Of the respondents, 48% of births occurred in a health facility and 52% in a non-institutional location. The significant determinants of facility delivery examined using multivariate analysis were: maternal education level, maternal health knowledge, ANC visits, birth interval, economic status of household, number of household members, household sanitation practices and traveling time to nearest health facility. CONCLUSIONS: The results suggest that the involvement of TBAs to promote facility delivery is still one of the most important strategies. Strengthening CHWs' performance by focusing on a limited number of topics and clear management guidance might also be an effective intervention. Stressing the importance of regular attendance at ANC (at least four times) would be effective in enhancing motivation for a facility delivery. Based on our findings, those actions to improve the facility delivery rate should focus more on pregnant women who have a low education level, poor health knowledge and short pregnancy spacing. In addition, women with low economic status, a large number of family members and a long distance to travel to a health facility should also be targeted by further interventions.

Folic acid supplementation and interpregnancy interval.

BACKGROUND: Maternal folic acid supplementation between subsequent pregnancies may be important to reduce the risk of low folate status associated with short interpregnancy intervals. We examined how the prevalence of preconception folic acid use for a given pregnancy in Norwegian women varied according to the time interval from the previous pregnancy. METHODS: Analysis was based on 48 855 pairs of pregnancies with the second pregnancy included in the Norwegian Mother and Child Cohort Study (birth years 1999-2009). Interpregnancy interval was defined as the time from birth of a child to the conception of the subsequent sibling. Preconception folic acid use was defined as any use of folic acid-containing supplements within the last 4 weeks before the second pregnancy. RESULTS: The prevalence of preconception folic acid use was 31%. Among women with a term birth (≥37 weeks) in the previous pregnancy (92%), those with interpregnancy intervals ≤12 and ≥49 months were associated with up to 35% lower prevalence of preconception folic acid use for the second pregnancy, relative to the reference group (13-24 months). The low use in short intervals was mainly attributable to lower proportion of planned pregnancies and fewer women with higher education. Among women with a preterm birth (<37 weeks) in the previous pregnancy (8%), preconception folic acid use significantly decreased with increasing pregnancy spacing. CONCLUSIONS: Our finding of a lower preconception folic acid use in women with both short and long interpregnancy intervals might help identifying those with higher risk of folate deficiency and preventing unwanted pregnancy outcomes.

Evidence-based interventions for improvement of maternal and child nutrition: what can be done and at what cost?

Maternal undernutrition contributes to 800,000 neonatal deaths annually through small for gestational age births; stunting, wasting, and micronutrient deficiencies are estimated to underlie nearly 3·1 million child deaths annually. Progress has been made with many interventions implemented at scale and the evidence for effectiveness of nutrition interventions and delivery strategies has grown since The Lancet Series on Maternal and Child Undernutrition in 2008. We did a comprehensive update of interventions to address undernutrition and micronutrient deficiencies in women and children and used standard methods to assess emerging new evidence for delivery platforms. We modelled the effect on lives saved and cost of these interventions in the 34 countries that have 90% of the world's children with stunted growth. We also examined the effect of various delivery platforms and delivery options using community health workers to engage poor populations and promote behaviour change, access and uptake of interventions. Our analysis suggests the current total of deaths in children younger than 5 years can be reduced by 15% if populations can access ten evidence-based nutrition interventions at 90% coverage. Additionally, access to and uptake of iodised salt can alleviate iodine deficiency and improve health outcomes. Accelerated gains are possible and about a fifth of the existing burden of stunting can be averted using these approaches, if access is improved in this way. The estimated total additional annual cost involved for scaling up access to these ten direct nutrition interventions in the 34 focus countries is Int$9·6 billion per year. Continued investments in nutrition-specific interventions to avert maternal and child undernutrition and micronutrient deficiencies through community engagement and delivery strategies that can reach poor segments of the population at greatest risk can make a great difference. If this improved access is linked to nutrition-sensitive approaches--ie, women's empowerment, agriculture, food systems, education, employment, social protection, and safety nets--they can greatly accelerate progress in countries with the highest burden of maternal and child undernutrition and mortality.

Nutritional management of the low birth weight/preterm infant in community settings: a perspective from the developing world.

Globally, about 20 million infants are born with low birth weight (LBW; <2500 g). Of all LBW infants, approximately 95% are born in developing countries. The greatest incidence of LBW occurs in South-Central Asia; the second greatest is in Africa. The two main reasons for LBW are preterm birth (<37 weeks) and intrauterine growth restriction (IUGR), which are risk factors for increased morbidity and mortality in newborn infants. Maternal nutrition status is one of the most important risk factors for LBW/IUGR. Providing balanced protein energy and multiple micronutrient supplements to pregnant women will reduce incidence of IUGR. Calcium supplementation during pregnancy will reduce the incidence of pre-eclampsia and preterm birth in developing countries. Exclusive breastfeeding is protective for a mother and her infant and has been shown to reduce morbidity and mortality in infancy. Kangaroo mother care for preterm infants will reduce severe morbidity and mortality as well. Community-based intervention packages are among the most effective methods of reducing morbidity and mortality in mothers and children. Future research should focus on improving triage of preterm and IUGR infants. Exclusive breastfeeding should be promoted, and appropriate alternative food supplements should be provided when breastfeeding is not possible.
