Maternal Literacy, Facility Birth, and Education Are Positively Associated with Better Infant and Young Child Feeding Practices and Nutritional Status among Ugandan Children.

BACKGROUND: Understanding maternal factors that influence child feeding is necessary to inform intervention planning in settings in which mothers experience substantial social vulnerabilities. OBJECTIVE: The purpose of this study was to assess maternal sociodemographic factors that may constrain women's caring capabilities and subsequent child nutrition in Uganda. METHODS: We analyzed data from the 2006 and 2011 Uganda Demographic and Health Surveys to model the associations between maternal sociodemographic factors, child feeding practices, and anthropometry with multivariate logistic regression models. RESULTS: The proportion of children fed according to recommended guidelines declined in Uganda from 2006 to 2011. Mothers who lacked literacy skills were less likely to achieve recommended complementary feeding indicators; however, literacy was not associated with breastfeeding practices. Mothers in the upper 60% wealth percentile were more likely to meet minimum meal frequency, diversity, and adequacy indicators. Mothers who gave birth at health facilities (2006 OR: 0.49; 95% CI: 0.26, 0.91; P < 0.05) and who were in the upper 60% wealth percentile (2011 OR: 0.43; 95% CI: 0.21, 0.69) were less likely to exclusively breastfeed until 6 mo. There were no significant associations between age at first pregnancy, maternal education, and infant and young child feeding practices. Women with a formal education had children with lower stunting and underweight probabilities in both time periods (OR range: 0.43-0.74). Women who delivered in childbirth facilities were less likely to have a child with low weight-for-age, length-for-age, or weight-for-length z scores (OR range: 0.59-0.82). Marital status, the age at first child birth, not accepting domestic violence, freedom to travel away from home, and involvement in household and reproductive decisions were not associated with child anthropometry in either time period. CONCLUSIONS: Mothers with low literacy skills, who deliver their children at home, and who lack formal education are particularly at risk of poor child feeding and represent a group that may benefit from enhanced interventions that address their particular vulnerabilities. Factors that contribute to improved maternal feeding capabilities but may impair breastfeeding practices need to be better understood.

Demand-side interventions for maternal care: evidence of more use, not better outcomes.

BACKGROUND: Reducing maternal and neonatal mortality is essential to improving population health. Demand-side interventions are designed to increase uptake of critical maternal health services, but associated change in service uptake and outcomes is varied. We undertook a literature review to understand current evidence of demand-side intervention impact on improving utilization and outcomes for mothers and newborn children. METHODS: We completed a rapid review of literature in PubMed. Title and abstracts of publications identified from selected search terms were reviewed to identify articles meeting inclusion criteria: demand-side intervention in low or middle-income countries (LMIC), published after September 2004 and before March 2014, study design describing and reporting on >1 priority outcome: utilization (antenatal care visits, facility-based delivery, delivery with a skilled birth attendant) or health outcome measures (maternal mortality ratio (MMR), stillbirth rate, perinatal mortality rate (PMR), neonatal mortality rate (NMR)). Bibliographies were searched to identify additional relevant papers. Articles were abstracted using a standardized data collection template with double extraction on a sample to ensure quality. Quality of included studies was assessed using McMaster University's Quality Assessment Tool from the Effective Public Health Practice Project (EPHPP). RESULTS: Five hundred and eighty two articles were screened with 50 selected for full review and 16 meeting extraction criteria (eight community mobilization interventions (CM), seven financial incentive interventions (FI), and one with both). We found that demand-side interventions were effective in increasing uptake of key services with five CM and all seven FI interventions reporting increased use of maternal health services. Association with health outcome measures were varied with two studies reporting reductions in MMR and four reporting reduced NMR. No studies found a reduction in stillbirth rate. Only four of the ten studies reporting on both utilization and outcomes reported improvement in both measures. CONCLUSIONS: We found strong evidence that demand-side interventions are associated with increased utilization of services with more variable evidence of their impact on reducing early neonatal and maternal mortality. Further research is needed to understand how to maximize the potential of demand-side interventions to improve maternal and neonatal health outcomes including the role of quality improvement and coordination with supply-side interventions.

Presynaptic to postsynaptic relationships of the neuromuscular junction are held constant across age and muscle fiber type.

The neuromuscular junction (NMJ) displays considerable morphological plasticity as a result of differences in activity level, as well as aging. This is true of both presynaptic and postsynaptic components of the NMJ. Yet, despite these variations in NMJ structure, proper presynaptic to postsynaptic coupling must be maintained in order for effective cell-to-cell communication to occur. Here, we examined the NMJs of muscles with different activity profiles (soleus and EDL), on both slow- and fast-twitch fibers in those muscles, and among young adult and aged animals. We used immunofluorescent techniques to stain nerve terminal branching, presynaptic vesicles, postsynaptic receptors, as well as fast/slow myosin heavy chain. Confocal microscopy was used to capture images of NMJs for later quantitative analysis. Data were subjected to a two-way ANOVA (main effects for myofiber type and age), and in the event of a significant (p < 0.05) F ratio, a post hoc analysis was performed to identify pairwise differences. Results showed that the NMJs of different myofiber types routinely displayed differences in presynaptic and postsynaptic morphology (although the effect on NMJ size was reversed in the soleus and the EDL), but presynaptic to postsynaptic relationships were tightly maintained. Moreover, the ratio of presynaptic vesicles relative to nerve terminal branch length also was similar despite differences in muscles, their fiber type, and age. Thus, in the face of considerable overall structural differences of the NMJ, presynaptic to postsynaptic coupling remains constant, as does the relationship between presynaptic vesicles and the nerve terminal branches that support them.
