THE INFLUENCE OF REGULAR BREAST MILK PUMPNG IN THE EARLY POSTPARTUM PERIOD ON BREASTFEEDING DURATION AND ACHIEVEMENT OF BREASTFEEDING INTENTION AMONG WOMEN IN THE U.S.

Most mothers do not breastfeed in accordance with health recommendations. Returning to work can be a barrier to breastfeeding due to mother-infant separation. Expressing breast milk (pumping) is a way for mothers to continue breastfeeding when separated from their infants, but it is not known if regular pumping influences breast milk feeding duration and achievement of breastfeeding intentions. I estimated effects of regular pumping compared to non-regular/not pumping (noted as “non-regular”) reported at month 2 on time to breast milk feeding (BMF) cessation (to 12 months) and time to exclusive BMF cessation (to six months), as well as achievement of breastfeeding and exclusive breastfeeding intentions, overall and for working and non-working women. I imputed missing data with 100 replications and used statistical weights to control for confounding and to address selection bias from the study design and drop-outs. Overall, regular pumpers were more likely to stop BMF and exclusive BMF (weighted hazard ratio (wHR) 1.62; 95% confidence interval (CI) 1.47 – 1.78 for BMF and wHR 1.14; 95% CI 1.03 – 1.25 for exclusive BMF), and less likely to meet their breastfeeding intentions than non-regular pumpers (weighted risk ratio (wRR) 0.79; 95% CI 0.67 – 0.94). I observed no difference in achievement of exclusive BMF intention (wRR 1.05; 95% CI 0.84 – 1.31). Among working women, I observed no effect of regular pumping compared to non-regular pumping, in terms of time to BMF cessation (wHR 0.90; 95% CI 0.75 – 1.07), exclusive BMF cessation (wHR 1.15; 95% CI 0.96 – 1.37), or achievement of breastfeeding intention (wRR 1.08; 95% CI 0.81 – 1.43) or exclusive breastfeeding intention (wRR 1.36; 95% CI 0.95 – 1.95). Among non-working women, regular pumpers had an increased hazard of BMF cessation (wHR 2.05; 95% CI 1.84 – 2.28), but not of exclusive BMF cessation (wHR 1.10; 95% CI 0.98 – 1.22), compared to non-regular pumpers. Regular pumpers were less likely to meet breastfeeding intentions (wRR 0.69; 95% CI 0.56 – 0.85), but had no difference in risk of not meeting exclusive breastfeeding intentions (wRR 0.70; 95% CI 0.69 – 1.22), than non-regular pumpers. Regular pumpers may need specialized support to maintain BMF and to achieve their intentions.Doctor of Philosoph

Women’s status, breastfeeding support, and breastfeeding practices in the United States

The objective of this study is to examine associations between state-level breastfeeding support and breastfeeding practices, controlling for women’s status, in the U.S. We used publicly available data on state-level breastfeeding practices and support (international board-certified lactation consultants (IBCLC), births in Baby-Friendly hospitals, and La Leche League Leaders) for births in 2015 from the CDC Breastfeeding Report Card (2018) and other CDC reported data, and indicators of women’s status from the Institute for Women’s Policy Research reports (2015). We conducted an ecological study to estimate incidence rate ratios of exclusive breastfeeding at six months and breastfeeding at 12 months with breastfeeding supports using bivariate and multivariable Poisson regression. Political participation, poverty, and employment and earnings were associated with breastfeeding practices, as was each breastfeeding support in bivariate analyses. After controlling for women’s status, only IBCLCs were positively associated with rates of exclusive breastfeeding at 6 months and continued breastfeeding at 12 months. For every additional IBCLC per 1000 live births, the rate of exclusive breastfeeding at 6 months increased by 5 percent (95% CI 1.03, 1.07) and the rate of breastfeeding at 12 months increased by 4 percent (95% CI 1.02, 1.06). Political participation, poverty, and employment and earnings were associated with breastfeeding practices, indicating a relationship between women’s political and economic status and their breastfeeding practices in the U.S. Given the influence of women’s status, increasing the number of IBCLCs may improve breastfeeding practices

Using geographical analysis to identify child health inequality in sub-Saharan Africa

One challenge to achieving Millennium Development Goals was inequitable access to quality health services. In order to achieve the Sustainable Development Goals, interventions need to reach underserved populations. Analyzing health indicators in small geographic units aids the identification of hotspots where coverage lags behind neighboring areas. The purpose of these analyses is to identify areas of low coverage or high need in order to inform effective resource allocation to reduce child health inequity between and within countries. Using data from The Demographic and Health Survey Program surveys conducted in 27 selected African countries between 2010 and 2014, we computed estimates for six child health indicators for subnational regions. We calculated Global Moran’s I statistics and used Local Indicator of Spatial Association analysis to produce a spatial layer showing spatial associations. We created maps to visualize sub-national autocorrelation and spatial clusters. The Global Moran’s I statistic was positive for each indicator (range: 0.41 to 0.68), and statistically significant (p <0.05), suggesting spatial autocorrelation across national borders, and highlighting the need to examine health indicators both across countries and within them. Patterns of substantial differences among contiguous subareas were apparent; the average intra-country difference for each indicator exceeded 20 percentage points. Clusters of cross-border associations were also apparent, facilitating the identification of hotspots and informing the allocation of resources to reduce child health inequity between and within countries. This study exposes differences in health indicators in contiguous geographic areas, indicating that specific regional and subnational, in addition to national, strategies to improve health and reduce health inequalities are warranted

Geospatial modeling of child mortality across 27 countries in Sub-Saharan Africa

Preventable mortality of children has been targeted as one of the UN’s Sustainable Development Goals for the 2015-30 period. Global decreases in child mortality (4q1) have been seen, although sub-Saharan Africa remains an area of concern, with child mortality rates remaining high relative to global averages or even increasing in some cases. Furthermore, the spatial distribution of child mortality in sub-Saharan Africa is highly heterogeneous. Thus, research that identifies primary risk factors and protective measures in the geographic context of sub-Saharan Africa is needed. In this study, household survey data collected by The Demographic and Health Surveys (DHS) Program aggregated at DHS sub-national area scale are used to evaluate the spatial distribution of child mortality (age 1 to 4) across 27 sub-Saharan Africa countries in relation to a number of demographic and health indicators collected in the DHS surveys. In addition, this report controls for spatial variation in potential environmental drivers of child mortality by modeling it against a suite of geospatial datasets. These datasets vary across the study area in an autoregressive spatial model that accounts for the spatial autocorrelation present in the data. This study shows that socio-demographic factors such as birth interval, stunting, access to health facilities and literacy, along with geospatial factors such as prevalence of Plasmodium falciparum malaria, variety of ethnic groups, mean temperature, and intensity of lights at night can explain up to 60% of the variance in child mortality across 255 DHS sub-national areas in the 27 countries. Additionally, three regions - Western, Central, and Eastern Africa - have markedly different mortality rates. By identifying the relative importance of policy-relevant socio-demographic and environmental factors, this study highlights priorities for research and programs targeting child mortality over the next decade. <br/

The development and initial validation of the Health and Reproductive Survey (HeRS).

Due to the diversity in profiles associated with the female reproductive cycle and their potential physiological and psychological effects, monitoring the reproductive status of exercising females is important from a practical and research perspective. Moreover, as physical activity can influence menstrual function, the effects of physical activity energy expenditure on reproductive function should also be considered. The aim of this study was to develop and establish initial face and content validity of the Health and Reproductive Survey (HeRS) for physically active females, which is a retrospective assessment of menstrual function from menarche (first menstruation) to menopause (cessation of menstruation). Face validity was evaluated qualitatively, and the initial content validity was established through a principal component analysis. The face validity process was completed by 26 females aged 19-67 years and the content validity was established through a survey sent to a convenience sample of 392 females, of which 230 females (57.9% and aged 18-49 years) completed the survey. The revisions made following the face validation improved the understanding, flow, and coherence of the survey. The principal component analysis indicated that, at a minimum, the survey measures these constructs: menstrual cessation and associated moderators, athletic participation and performance levels (as associated with menstruation change and the menstrual cycle), age and menstrual cessation, hormonal contraception ("birth control"), and menarche and associated moderators. The Health and Reproductive Survey (HeRS) is a partially validated tool that can be used by researchers to characterize the menstrual status of physically active females relative to their physical activity status

Engaging men to promote and support exclusive breastfeeding: a descriptive review of 28 projects in 20 low- and middle-income countries from 2003 to 2013

Abstract Background Lay support has been associated with improved breastfeeding practices, but studies of programs that engage men in breastfeeding support have shown mixed results and most are from high-income countries. The purpose of our research is to review strategies to engage men in exclusive breastfeeding (EBF) promotion or support in 28 project areas across 20 low- and middle-income countries. This information may be used to inform program implementers and policymakers seeking to increase EBF. Methods We tested the difference between baseline and final EBF proportions using Pearson’s chi-square (a = 0.05) and identified project areas with a significant increase. We categorized male engagement strategies as low- and high-intensity, using information from project reports. We looked for patterns by intensity and geography and described strategies used to engage men in different places. Results Twenty-eight projects were reviewed; 21 (75%) were in areas where a statistically significant increase in EBF was observed between the beginning and end of the project. A variety of high- and low-intensity male engagement strategies was used in areas with an increase in EBF prevalence and in all geographic regions. High-intensity strategies engaged men directly during home or health visits by forming men’s groups and by working with male community leaders or members to promote EBF. Low-intensity strategies included large community meetings that included men, and radio messages, and other behavior change materials directed towards men. Conclusion Male engagement strategies took many forms in these project areas. We did not find consistent associations between the intensities or types of male engagement strategies and increases in EBF proportions. There is a gap in understanding how gender norms might impact male involvement in women’s health behaviors. This review does not support the broad application of male engagement to improve EBF practices, and we recommend considering local gender norms when designing programs to support women to EBF

Interactions among poverty, gender, and health systems affect women's participation in services to prevent HIV transmission from mother to child: A causal loop analysis

Retention in care remains an important issue for prevention of mother-to-child transmission (PMTCT) programs according to WHO guidelines, formerly called the ªOption B+º approach. The objective of this study was to examine how poverty, gender, and health system factors interact to influence women's participation in PMTCT services. We used qualitative research, literature, and hypothesized variable connections to diagram causes and effects in causal loop models. We found that many factors, including antiretroviral therapy (ART) use, service design and quality, stigma, disclosure, spouse/partner influence, decision- making autonomy, and knowledge about PMTCT, influence psychosocial health, which in turn affects women's participation in PMTCT services. Thus, interventions to improve psychosocial health need to address many factors to be successful. We also found that the design of PMTCT services, a modifiable factor, is important because it affects several other factors. We identified 66 feedback loops that may contribute to policy resistanceÐthat is, a policy's failure to have its intended effect. Our findings point to the need for a multipronged intervention to encourage women's continued participation in PMTCT services and for longitudinal research to quantify and test our causal loop model

We did not find consistent associations between the intensities or types of male engagement strategies and increases in EBF proportions. There is a gap in understanding how gender norms might impact male involvement in women\u2019s health behaviors. This review does not support the broad application of male engagement to improve EBF practices, and we recommend considering local gender norms when designing programs to support women to EBF

Systematic review of metrics used to characterise dietary nutrient supply from household consumption and expenditure surveys.

OBJECTIVE: To review existing publications using Household Consumption and Expenditure Survey (HCES) data to estimate household dietary nutrient supply to (1) describe scope of available literature, (2) identify the metrics reported and parameters used to construct these metrics, (3) summarise comparisons between estimates derived from HCES and individual dietary assessment data and (4) explore the demographic and socio-economic sub-groups used to characterise risks of nutrient inadequacy. DESIGN: This study is a systematic review of publications identified from online databases published between 2000 to 2019 that used HCES food consumption data to estimate household dietary nutrient supply. Further publications were identified by 'snowballing' the references of included database-identified publications. SETTING: Publications using data from low- and lower-middle income countries. RESULTS: In total, fifty-eight publications were included. Three metrics were reported that characterised household dietary nutrient supply: apparent nutrient intake per adult-male equivalent per day (n 35), apparent nutrient intake per capita per day (n 24) and nutrient density (n 5). Nutrient intakes were generally overestimated using HCES food consumption data, with several studies finding sizeable discrepancies compared with intake estimates based on individual dietary assessment methods. Sub-group analyses predominantly focused on measuring variation in household dietary nutrient supply according to socio-economic position and geography. CONCLUSION: HCES data are increasingly being used to assess diets across populations. More research is needed to inform the development of a framework to guide the use of and qualified interpretation of dietary assessments based on these data

Modeling food fortification contributions to micronutrient requirements in Malawi using Household Consumption and Expenditure Surveys.

Large-scale food fortification may be a cost-effective intervention to increase micronutrient supplies in the food system when implemented under appropriate conditions, yet it is unclear if current strategies can equitably benefit populations with the greatest micronutrient needs. This study developed a mathematical modeling framework for comparing fortification scenarios across different contexts. It was applied to model the potential contributions of three fortification vehicles (oil, sugar, and wheat flour) toward meeting dietary micronutrient requirements in Malawi through secondary data analyses of a Household Consumption and Expenditure Survey. We estimated fortification vehicle coverage, micronutrient density of the diet, and apparent intake of nonpregnant, nonlactating women for nine different micronutrients, under three food fortification scenarios and stratified by subpopulations across seasons. Oil and sugar had high coverage and apparent consumption that, when combined, were predicted to improve the vitamin A adequacy of the diet. Wheat flour contributed little to estimated dietary micronutrient supplies due to low apparent consumption. Potential contributions of all fortification vehicles were low in rural populations of the lowest socioeconomic position. While the model predicted large-scale food fortification would contribute to reducing vitamin A inadequacies, other interventions are necessary to meet other micronutrient requirements, especially for the rural poor
