Comprehensive analysis of the association of seasonal variability with maternal and neonatal nutrition in lowland Nepal

Seasonal variations in household food security and consumption affect women's nutritional status in rural South Ethiopia

Food availability varies seasonally in most rural areas of developing nations, especially in areas affected by drought and climate change, with women being one of the most vulnerable groups. This study aimed to assess the effect of seasonal variation in household food security, adequate dietary diversity, food consumption, and wealth on the nutritional status of women of reproductive age in a rural community in South Ethiopia. Further, the study aimed at identifying associated factors with women's nutrition status. An open cohort study was conducted from June 2021 to June 2022, with follow-up visits every three months. Anthropometric measurements were carried out along with interviews. Data were analyzed using STATA version 15. Multilevel, multiple linear regressions were employed. Findings revealed that women's average body mass index (BMI) was 20.4 kg/m2 (95% CI: 20.4-20.5). The highest (20.6 kg/m2, 95% CI: 20.5-20.8) was observed in December, while the lowest (20.2 kg/m2, 95% CI: 20-20.3) occurred in September. During the main postharvest period in December, the household food insecurity score was the lowest (median: 4, Inter quartile range (IQR): 0-9), while the household dietary diversity score (median: 6, IQR: 5-7), and the household food consumption score were the highest (median: 50.5, IQR: 44-70). Factors such as household food security, food consumption, previous season BMI, age, marital status, and membership in safety net programs were identified as determinants of women's BMI. The study showed the vulnerability of women in drought-prone areas to seasonal undernutrition. We recommend collaborative work among stakeholders to ensure sustainable food access and minimize seasonal food shortages' effect on women's nutrition and overall well-being.

The practice of key essential nutrition actions among pregnant women in southwest Ethiopia: implications for optimal pregnancy outcomes

BACKGROUND

Nutrition during pregnancy is a major determinant of human health and child development, and the role of promoting essential nutrition actions (ENA) is of a paramount importance for the health of the mother and newborn. However, the practice of ENA could be hampered by many factors, which need to be understood for tailored actions. This study assessed the practice of key ENAs and associated factors among pregnant mothers in southwest Ethiopia.

METHOD

A community-based cross-sectional study was employed among 373 pregnant mothers. A simple random sampling method was used to select the study participants. The data was entered into EpiData Manager and exported to SPSS version 21 for analysis. A bivariable logistic regression was conducted to explore the association between independent variables and the outcome variable. Variables with p-values less than 0.25 during bivariable analysis were entered into a multivariable logistic regression model. Level of statistical significance was declared at a p-value below 0.05. The crude and adjusted odds ratios, along with the 95% CI, were estimated to measure the strength of the association between the dependent variables and independent variables.

RESULT

In this study, 373 pregnant mothers have participated, with a response rate of 97%. A total of 275 (73.7%; 95% CI: 68.9-78.0) women practiced key essential nutrition actions at optimal level. Monthly household income of 2500 ETB (AOR = 0.45, 95% CI: 0.23, 0.89), rural residence (AOR = 2.31, 95% CI: 1.25, 4.4), and poor knowledge of key ENA messages (AOR = 3.36, 95% CI: 1.81, 6.26) were factors that were significantly associated with poor practice of key ENA messages.

CONCLUSIONS

The practice of key ENA messages was poor and closely linked to household income, residence, and knowledge of pregnant women's on ENA key messages. Therefore, nutritional intervention with a focus on intensified nutritional counseling is needed for better adoption of key ENA practices.

Child wasting and concurrent stunting in low- and middle-income countries

Sustainable Development Goal 2.2-to end malnutrition by 2030-includes the elimination of child wasting, defined as a weight-for-length z-score that is more than two standard deviations below the median of the World Health Organization standards for child growth1. Prevailing methods to measure wasting rely on cross-sectional surveys that cannot measure onset, recovery and persistence-key features that inform preventive interventions and estimates of disease burden. Here we analyse 21 longitudinal cohorts and show that wasting is a highly dynamic process of onset and recovery, with incidence peaking between birth and 3 months. Many more children experience an episode of wasting at some point during their first 24 months than prevalent cases at a single point in time suggest. For example, at the age of 24 months, 5.6% of children were wasted, but by the same age (24 months), 29.2% of children had experienced at least one wasting episode and 10.0% had experienced two or more episodes. Children who were wasted before the age of 6 months had a faster recovery and shorter episodes than did children who were wasted at older ages; however, early wasting increased the risk of later growth faltering, including concurrent wasting and stunting (low length-for-age z-score), and thus increased the risk of mortality. In diverse populations with high seasonal rainfall, the population average weight-for-length z-score varied substantially (more than 0.5 z in some cohorts), with the lowest mean z-scores occurring during the rainiest months; this indicates that seasonally targeted interventions could be considered. Our results show the importance of establishing interventions to prevent wasting from birth to the age of 6 months, probably through improved maternal nutrition, to complement current programmes that focus on children aged 6-59 months.

Scale-Up of a Newborn Resuscitation Capacity-Building and Skill Retention Program Associated With Improved Neonatal Outcomes in Gandaki Province, Nepal

BACKGROUND

Intrapartum events leading to asphyxia at birth are a leading cause of neonatal morbidity and mortality in Nepal. In response, the Nepal Ministry of Health and Population adopted the Helping Babies Breathe (HBB) training curriculum in 2015 as a tool to improve neonatal resuscitation and outcomes. Although the effectiveness of HBB training has been well documented, challenges remain in maintaining skills over time. Safa Sunaulo Nepal (SSN) designed an evidence-based intervention for scaling up newborn resuscitation training and skill retention. We report on its implementation and the changes in newborn outcomes during the program period.

METHODS

The program empowered facility-based trainers in newborn resuscitation and skill retention at 12 facilities in Gandaki Province. Seven of 14 level I hospitals and 5 of 6 level II hospitals were selected. A single external mentor coached the facility-based trainers, provided general support, and monitored progress. Program evaluation tracked changes in newborn metrics over 21 Nepali months (March 2018-November 2019). All deliveries occurring in the health facilities during the program period were included in the evaluation. We assessed program effectiveness by analyzing time trends of neonatal mortality, morbidity, and stillbirths.

RESULTS

We gathered data on neonatal health outcomes of 33,417 deliveries, including 23,820 vaginal deliveries and 9,597 cesarean deliveries. During the program, 43 facility-based trainers taught resuscitation skills to 425 medical personnel and supported skill retention. Neonatal deaths within 24 hours of birth (incidence rate ratio [IRR]=0.993, P=.044) and newborn morbidities (IRR=0.996, P<.001) showed a significantly declining trend.

CONCLUSION

Our findings suggest that the SSN program had a substantial influence on critical neonatal outcomes. Future neonatal resuscitation capacity-building and skill retention efforts may benefit from incorporating elements of the program.

Seasonality- and disaster effects on food variety and food insecurity coping strategies among a landslide-prone cohort

BACKGROUND & AIMS

Landslides may impact on nutritional health among vulnerable populations. However, there is limited data on the seasonal effects of landslides on diet and food security. Among the 2010 and 2018 households affected by the landslides in Eastern Uganda, we assessed seasonality and disaster effects on food varieties consumed and food insecurity coping strategies. This study is among the first to report on seasonal- and disaster effects on food varieties and food insecurity coping strategies among vulnerable populations in Uganda.

METHODS

We used a three-stage simple random technique to select a total of 422 households during May-August (food-plenty season) in 2019, of whom 211 had been affected by the landslides and 211 had not (controls). Six months later, in January-March (food-poor season) of 2020, 388 households were re-assessed (191 affected and 197 controls). We analyzed data only from the households that participated in both food seasons to compare results between the two food seasons. Food variety scores (FVS) were obtained by summing the frequency of weekly intakes of 86 food items while a coping index was derived based on the severity weighting of household food insecurity coping strategies.

RESULTS

After adjusting for covariates, significantly lower mean (SE) FVS were among the affected than controls during the food-plenty season: 9.3 (0.5) vs 11.4 (0.3), and during the food-poor season: 7.6 (0.5) vs 10.1 (0.1) (P < 0.001 for both). The affected households were more likely to use food insecurity coping strategies compared to controls (mean [SE]: 35.2 [2.1] vs. 27.1 [1.8], P < 0.001) during the food-plenty season and the severity further increased during the food-poor season: 42.1 (2.1) vs. 28.2 (2.1) (P < 0.001). Disaster exposure was associated with both household food varieties and food insecurity coping strategies during both food seasons (P < 0.001). The adjusted models, showed that, the affected compared to the controls had a significantly higher likelihood to rely on 5 of the 11 coping strategies during food-plenty season and 9 of the 11 coping strategies during the food-poor season.

CONCLUSION

Low variety diets and coping strategies among disaster affected individuals cut across seasons and implies needs for strong social protection and targeted safety nets irrespective of season.

Associations of maternal age at marriage and pregnancy with infant undernutrition: Evidence from first‐time mothers in rural lowland Nepal

Objectives

Maternal factors shape the risk of infant undernutrition, however the contributions of age at marriage versus age at pregnancy are rarely disentangled. We explore these issues in a population from lowland rural Nepal, where median ages at marriage and first pregnancy are 15 and 17 years respectively and marriage almost always precedes pregnancy.

Methods

We analyzed data on first‐time mothers (n = 3002) from a cluster‐randomized trial (2012–2015). Exposures were ages at marriage and pregnancy, categorized into groups. Outcomes were z‐scores for weight (WAZ), length (LAZ), head circumference (HCAZ), and weight‐for‐length (WLZ), and prevalence of wasting and stunting, for neonates (<8 days) and infants (6–12 months). Mixed linear and logistic regression models tested associations of marriage and pregnancy ages with outcomes, adjusting for parental education, household assets, caste, landholding, seasonality, child sex, intervention arm, randomization strata and cluster.

Results

For neonates, pregnancy <18 years predicted lower LAZ, and <19 years predicted lower WAZ and HCAZ. Results were largely null for marriage age, however early pregnancy and marriage at 10–13 years independently predicted neonatal stunting. For infants, earlier pregnancy was associated with lower LAZ and HCAZ, with a trend to lower WAZ for marriage 10–13 years. Early pregnancy, but not early marriage, predicted infant stunting.

Conclusions

Early marriage and pregnancy were associated with poorer growth, mainly in terms of LAZ and HCAZ. Associations were stronger for neonatal than infant outcomes, suggesting pregnancy is more susceptible to these stresses. Early marriage and pregnancy may index different social and biological factors predicting child undernutrition.

The impact of climate change on children's nutritional status in coastal Bangladesh

This paper studies the impact of climate change on the nutritional status of very young children between the ages of 0-3 years by using weather data from the last half century merged with rich information on child, mother, and household characteristics in rural coastal Bangladesh. We evaluate the health consequences of rising temperature and relative humidity and varying rainfall jointly employing alternate functional forms. Leveraging models that control for annual trends and location-specific seasonality, and that allow the impacts of temperature to vary non-parametrically while rainfall and humidity have flexible non-linear forms, we find that temperatures that exceed 25 °C (the "comfortable" benchmark) in the month of birth exert negative effects on children's nutritional status as measured by mid upper arm circumference. Humidity has a positive impact which persists when child, mother and household controls are included. We find that exposure to changing climate in utero also matters. Explanations for these results include consequences of weather fluctuations on the extent of pasture, cropland, and rainfed lands planted with rice and other crops, and on mother's age at first marriage. Our results underline that climate change has real consequences for the health of very young populations in vulnerable areas.

Relative power: Explaining the effects of food and cash transfers on allocative behaviour in rural Nepalese households

We estimate the effects of antenatal food and cash transfers with women's groups on household allocative behaviour and explore whether these effects are explained by intergenerational bargaining among women. Interventions were tested in randomised-controlled trial in rural Nepal, in a food-insecure context where pregnant women are allocated the least adequate diets. We show households enrolled in a cash transfer intervention allocated pregnant women with 2-3 pp larger shares of multiple foods (versus their mothers-in-law and male household heads) than households in a control group. Households in a food transfer intervention only increased pregnant women's allocation of staple foods (by 2 pp). Intergenerational bargaining power may partly mediate the effects of the cash transfers but not food transfers, whereas household food budget and nutrition knowledge do not mediate any effects. Our findings highlight the role of intergenerational bargaining in determining the effectiveness of interventions aiming to reach and/or empower junior women.

Associations between early marriage and preterm delivery: Evidence from lowland Nepal

OBJECTIVES

Preterm delivery (<37 weeks gestation) is the largest cause of child mortality worldwide. Marriage and pregnancy during adolescence have been associated with an increased risk of preterm delivery. We investigate independent associations of age at marriage and age at first pregnancy with preterm delivery in a cohort of women from rural lowland Nepal.

METHODS

We analyzed data from 17 974 women in the Low Birth Weight South Asia Trial. Logistic regression models tested associations of age at marriage and age at first pregnancy with preterm delivery, for primigravida (n = 6 243) and multigravida (n = 11 731) women. Models were adjusted for maternal education, maternal caste, and household asset score.

RESULTS

Ninety percent of participants had married at <18 years and 58% had their first pregnancy at <18 years. 20% of participants delivered preterm. Primigravida participants married at ≤14 years had higher odds of preterm delivery than those married ≥18 years, when adjusting for study design (adjusted odds ratio (aOR) 1.45, 95% CI: 1.15-1.83), confounders (aOR 1.28: 1.01-1.62) and confounders + age at pregnancy (aOR 1.29: 1.00-1.68). Associations were insignificant for multigravida women. No significant associations were observed between age at first pregnancy and preterm delivery.

DISCUSSION

In this population, early marriage, rather than pregnancy, is a risk factor for preterm delivery. We hypothesize that psychological stress, a driver of preterm delivery which is increased among those marrying young, rather than physiological immaturity, drives this association. Further research into the psychological consequences of child marriage in Nepal is needed.
