Child stunting and anemia are intractable public health problems in developing countries and have profound short- and long-term consequences. The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial is motivated by the premise that environmental enteric dysfunction (EED) is a major underlying cause of both stunting and anemia, that chronic inflammation is the central characteristic of EED mediating these adverse effects, and that EED is primarily caused by high fecal ingestion due to living in conditions of poor water, sanitation, and hygiene (WASH). SHINE is a proof-of-concept, 2 × 2 factorial, cluster-randomized, community-based trial in 2 rural districts of Zimbabwe that will test the independent and combined effects of protecting babies from fecal ingestion (factor 1, operationalized through a WASH intervention) and optimizing nutritional adequacy of infant diet (factor 2, operationalized through an infant and young child feeding [IYCF] intervention) on length and hemoglobin at 18 months of age. Within SHINE we will measure 2 causal pathways. The program impact pathway comprises the series of processes and behaviors linking implementation of the interventions with the 2 child health primary outcomes; it will be modeled using measures of fidelity of intervention delivery and household uptake of promoted behaviors and practices. We will also measure a range of household and individual characteristics, social interactions, and maternal capabilities for childcare, which we hypothesize will explain heterogeneity along these pathways. The biomedical pathway comprises the infant biologic responses to the WASH and IYCF interventions that ultimately result in attained stature and hemoglobin concentration at 18 months of age; it will be elucidated by measuring biomarkers of intestinal structure and function (inflammation, regeneration, absorption, and permeability); microbial translocation; systemic inflammation; and hormonal determinants of growth and anemia among a subgroup of infants enrolled in an EED substudy. This article describes the rationale, design, and methods underlying the SHINE trial.Clinical Trials Registration. NCT01824940.

Contextual and cultural influences on parental feeding practices among Hispanics Hispanic preschoolers in the United States are at greater risk for obesity compared to non‐Hispanic whites. Obese children are more likely to be obese adolescents and adults thus, early prevention is critical. Growing evidence has addressed the role of caregivers’ indulgent or restrictive feeding practices in children’s eating behaviors and negative weight outcomes. However, the mechanisms driving these associations are largely unknown; including what influences these feeding practices among Hispanics. Therefore the goal of this qualitative study was to explore contextual and socio‐cultural influences on parental feeding. Four focus groups (n=37) were held with Hispanic parents of preschool‐aged children at two day care centers in Rhode Island. Audio recordings were transcribed and translated, and themes extracted. Parents commented that their childhood experiences of not being allowed to waste food influenced how they currently feed their children. They reported making conscious decisions not to use the same feeding strategies as their own parents and on the contrary, reported using different practices related to encouragement of healthy foods and promotion of self‐regulation. Parents reported wanting to feed their children healthy foods but other influences such as peer‐social interactions posed as challenges for example, some mother’s reported only buying juice after their child was exposed to it in daycare. Husband’s food preferences and grandparent’s indulgent behaviors were also viewed as a challenge to promoting healthy foods in the home. Understanding how cultural and environmental factors influence parental feeding and may help tailor obesity prevention efforts among Hispanics.

Fathers, grandmothers, and other family members’ influence on maternal, infant, and young child nutrition (MIYCN) is widely recognized, yet synthesis of the effectiveness of engaging them to improve nutrition practices during the first 1000 d is lacking. We examined the impact of behavioral interventions to engage family members in MIYCN in low- and middle-income countries through a mixed-methods systematic review. We screened 5733 abstracts and included 35 peer-reviewed articles on 25 studies (16 with quantitative and 13 with qualitative data). Most quantitative studies focused on early breastfeeding, primarily engaging fathers or, less often, grandmothers. Most found positive impacts on exclusive breastfeeding rates and family members’ knowledge and support. The few quantitative studies on complementary feeding, maternal nutrition, and multiple outcomes also suggested benefits. Qualitative themes included improved nutrition behaviors, enhanced relationships, and challenges due to social norms. Interventions engaging family members can increase awareness and build support for MIYCN, but more rigorous study designs are needed.

The WHO issued a strong recommendation that pregnant women be provided calcium supplements to prevent preeclampsia. This is the first recommended nutritional intervention to prevent this condition, a leading cause of maternal mortality globally. As health systems seek to implement this new intervention, a number of issues require further clarification and guidance, including dosage regimen, supplement formulation, and alignment with other antenatal nutritional interventions. We summarize key evidence on the above points and offer our views on good practices. Most developing countries have low calcium intake, so where habitual calcium intake is unknown, calcium supplements are likely beneficial. In our view, policymakers and program planners should consider adopting doses between 1.0 and 1.5 g elemental calcium/d, depending on the local average and variation in dietary calcium intake, logistical feasibility, and acceptability in the target population. Prudent practice would entail daily administration as calcium carbonate administered in divided doses of not >500 mg elemental calcium per dose. For ease of prescribing and adherence, calcium [as with iron and folic acid (IFA)] should be administered routinely to pregnant women from the earliest contact in pregnancy until delivery. Calcium's acute inhibitory effect on iron absorption translates to minimal effects in clinical studies. Therefore, to simplify the regimen and facilitate adherence, providers should not counsel that calcium and IFA pills must be taken separately. Although further research will shed more light on clinical and programmatic issues, policies can be implemented with ongoing revision as we continue to learn what works to improve maternal and newborn health.

The World Health Organization now recommends integrating calcium supplements into antenatal micronutrient supplementation programmes to prevent pre-eclampsia, a leading cause of maternal mortality. As countries consider integrating calcium supplementation into antenatal care (ANC), it is important to identify context-specific barriers and facilitators to delivery and adherence. Such insights can be gained from women's and health workers' experiences with iron and folic acid (IFA) supplements. We conducted in-depth interviews with 22 pregnant and post-partum women and 20 community-based and facility-based health workers in Kenya to inform a calcium and IFA supplementation programme. Interviews assessed awareness of anaemia, pre-eclampsia and eclampsia; ANC attendance; and barriers and facilitators to IFA supplement delivery and adherence. We analyzed interviews inductively using the constant comparative method. Women and health workers identified poor diet quality in pregnancy as a major health concern. Neither women nor health workers identified pre-eclampsia, eclampsia, anaemia or related symptoms as serious health threats. Women and community-based health workers were unfamiliar with pre-eclampsia and eclampsia and considered anaemia symptoms normal. Most women had not received IFA supplements, and those who had received insufficient amounts and little information about supplement benefits. We then developed a multi-level (health facility, community, household and individual) behaviour change strategy to promote antenatal calcium and IFA supplementation. Formative research is an essential first step in guiding implementation of antenatal calcium supplementation programmes to reduce pre-eclampsia. Because evidence on how to implement successful calcium supplementation programmes is limited, experiences with antenatal IFA supplementation can be used to guide programme development.

A potential bottleneck for increasing the adoption of child health interventions has been limited attention to designing actions that are built on the essential role that caregivers play in determining their effectiveness. In the Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial, we utilize the concept of maternal capabilities to examine participants' skills and attributes that affect their ability to provide appropriate care for their young child, fully engage with trial interventions, and influence the response to these interventions at the household level. We hypothesize that the impact of SHINE interventions on child stunting and anemia will be modified by these maternal capabilities. Drawing upon multiple theories, we identify and define critical maternal capabilities domains, and describe how they are measured in the trial. Description of maternal capabilities and their role as potential modifiers on impact will increase understanding of the impact of SHINE interventions, and the generalizability of our findings.

WHO guidelines recommend integrating calcium supplementation into antenatal care (ANC) alongside iron and folic acid (IFA) to reduce maternal mortality. However, supplementation programs face multiple barriers, and strategies to improve adherence are needed. An adherence partner is someone whom pregnant women ask to support adherence at home. This study ) assessed adherence partner acceptability, feasibility, and associations with calcium and IFA supplement adherence and) examined relations between social support and adherence. This secondary analysis is from a trial integrating calcium supplementation into ANC in Kenya. ANC providers were trained on calcium and IFA supplementation and counseling, provided with behavior change materials, and given adequate supplement supplies. Pregnant women from 16 government health facilities were recruited ( = 1036); sociodemographic and adherence data were collected at baseline and at 4- to 6-wk follow-up visits. Adherence was measured with pill counts and self-reports. Culturally adapted scales measured social support in general and specific to adherence. Mixed-effects regression analyses were used to examine factors associated with adherence partners, social support, and adherence. Most participants received information about adherence partners (91%) and had a partner at follow-up (89%). Participants with adherence partners reported higher adherence support (OR: 2.10; 95% CI: 1.32, 3.34). Mean ± SD adherence was high for calcium (88.3% ± 20.7%) and IFA (86.1% ± 20.9%). Adherence support was positively associated with calcium adherence at follow-up by using pill counts (OR: 2.2; 95% CI: 1.1, 2.6) and self-report data (OR: 1.9; 95% CI: 1.2, 2.9), but there was not a direct relation between adherence partners and adherence. Adherence support enhanced adherence to calcium supplements. The adherence partner strategy was highly acceptable and feasible but warrants further study. This research demonstrates the importance of adherence support and suggests that interventions to increase household-level support for antenatal micronutrient supplementation may be needed to implement the WHO guidelines.
