RESUMEN

Increased access to a variety of foods in low-and-middle-income countries (LMICs) has led to greater autonomy in food choice decision-making. Autonomy allows individuals to make decisions through negotiation of considerations in ways that are consistent with basic values. The aim of this study was to identify and describe how basic human values drive food choice in two diverse populations with transitioning food environments living in the neighboring East African countries of Kenya and Tanzania. Secondary data analysis was carried out on focus group discussions conducted with men and women in Kenya (n = 28) and Tanzania (n = 28) as part of prior studies on food choice. A priori coding based on Schwartz's theory of basic human values was conducted, followed by a narrative comparative analysis, which included review by original principal investigators. Values of conservation (security, conformity, tradition), openness to change (self-directed thought and action, stimulation, indulgence), self-enhancement (achievement, power, face), and self-transcendence (benevolence-dependability and -caring) were prominent drivers of food choice in both settings. Participants described how values were negotiated and highlighted existing tensions. For example, the value of tradition was cited as important in both settings but changing food contexts (e.g., new foods, diverse neighborhoods) increased prioritization of values like stimulation, indulgence, and self-directed thought and action. The application of a basic values framework was useful for understanding food choice in both settings. A focused understanding of how values drive food choice decision-making in the context of changing food availability in LMICs is essential for the promotion of sustainable healthy diets.

RESUMEN

BACKGROUND: Home fortification of complementary foods with multiple micronutrient powders (MNPs) is recommended to reduce child anemia in resource-poor settings. However, evidence of program effectiveness in India to guide policies and programs is lacking. OBJECTIVES: We implemented a large-scale intervention of MNPs in Bihar, India. The primary outcome was MNP consumption and change in hemoglobin concentration among children aged 6-18 mo between baseline and endline (12 mo). Secondary outcomes were change in child weight and length and infant and young child feeding (IYCF) practices (initiation, diversity, and feeding frequency). Ad hoc analyses included changes in anemia; stunting; underweight; wasting; and reported diarrhea, fever, and hospitalization. METHODS: We conducted a cluster-randomized, effectiveness trial in >4000 children within the context of ongoing health and nutrition programs implemented by CARE, India. Seventy health subcenters were randomly assigned to receive either MNPs with IYCF counseling (intervention) or IYCF counseling only (control). We used an adjusted difference-in-difference approach using repeat cross-sectional surveys at baseline and endline to evaluate impact. RESULTS: At baseline, 75% of intervention and 69% of control children were anemic and 33% were stunted. By endline, 70% of intervention households reported their child had ever consumed MNPs, and of those, 64% had consumed MNPs in the past month. Relative to control, hemoglobin concentration increased (0.22 g/dL; 95% CI: 0.00, 0.44 g/dL) and anemia declined by 7.1 percentage points (pp) (95% CI: -13.5, -0.7 pp). There was no impact on anthropometry nor IYCF practices. However, there was a decline of 8.0 pp (95% CI: -14.9, -1.1 pp) in stunting among children aged 12-18 mo. Diarrhea prevalence in the past 2 wk was reduced by 4.0 pp (95% CI: -7.6, -0.4 pp). CONCLUSIONS: Home fortification of complementary foods within a government-run program in Bihar had moderate compliance and caused modest improvements in hemoglobin and reductions in anemia and diarrhea prevalence.

RESUMEN

Mycotoxins are carcinogenic secondary metabolites of fungi that have been linked to infant growth faltering. In this study, we quantified co-occurring mycotoxins in breast milk and food samples from Haryana, India, and characterized determinants of exposure. Deterministic risk assessment was conducted for mothers and infants. We examined levels of eight mycotoxins (Aflatoxin B1 , B2 , G1 , G2 , M1 , M2 ; Ochratoxin A, B) in 100 breast milk samples (infants 2-4 months) using ultra-high-performance liquid chromatography tandem mass spectrometry. Aflatoxin B1 (AFB1 ), fumonisin B1 (FB1 ) and deoxynivalenol (DON) were detected in several food items (n = 298) using enzyme-linked immunosorbent assays. We report novel data on the presence of mycotoxins in breast milk samples from India. Whereas breast milk concentrations (AFM1 median: 13.7; range: 3.9-1200 ng/L) remain low, AFM1 was detected above regulatory limits in 27% of animal milk samples. Additionally, 41% of infants were above provisional maximum tolerable daily intake (PMTDI) limits for AFM1 due to consumption of breast milk (mean: 3.04, range: 0.26-80.7 ng kg-1 bw day-1 ). Maternal consumption of breads (p < 0.05) was associated with breast milk AFM1 exposure. AFB1 (µg/kg) was detected in dried red chilies (15.7; 0-302.3), flour (3.13; 0-214.9), groundnuts (0; 0-249.1), maize (56.0; 0-836.7), pearl millet (1.85; 0-160.2), rice (0; 0-195.6), wheat (1.9; 0-196.0) and sorghum (0; 0-63.5). FB1 (mg/kg) was detected in maize (0; 0-61.4), pearl millet (0; 0-35.4) and sorghum (0.95; 0-33.2). DON was not detected in food samples. Mothers in our study exceeded PMTDI recommendations for AFB1 due to consumption of rice and flour (mean: 75.81; range: 35.2-318.2 ng kg-1 bw day-1 ). Our findings show the presence of Aflatoxin B1 and M1 at various levels of the food chain and in breast milk, with estimated intakes exceeding PMTDI recommendations. Aflatoxins are known carcinogens and have also been linked to stunting in children. Their presence across the food system and in breast milk is concerning, thus warranting further research to replicate and expand on our findings and to understand implications for maternal and child health.

RESUMEN

BACKGROUND: Population growth which has resulted in a need for increased crop yields to sustain food security, in addition to the effects of climate change, have led to the widespread use of chemical pesticides. The indiscriminate use of pesticides has in turn led to contamination of the environment, food commodities and bioaccumulation in human tissues, particularly in agrarian regions of India including the northern state of Haryana. METHODS: We conducted a pilot screening study to investigate the presence of organochlorine, organophosphate, and pyrethroid pesticides in breastmilk samples (n = 75) from Haryana, India. Pesticide analyses were conducted using gas chromatography mass spectrometry (GC-MS) for OC and OP pesticides and GC-electron capture detector for pyrethroids. The study was complemented by a qualitative evaluation of maternal and community perceptions, knowledge, attitudes and practices associated with pesticide use and risk of exposure (n = 30 in-depth interviews; n = 9 focus group discussions). RESULTS: Analysis of breastmilk showed the presence of p,p'-dichlorodiphenyltrichloroethane (DDT) and p,p'-dichlorodiphenyldichloroethylene (DDE) in 4% (range:

RESUMEN

This paper describes the use of program-monitoring data to track program performance and inform activities. Monitoring data were collected as part of an effectiveness trial of multiple micronutrient powders (MNPs) for children 6-18 months in Bihar, India. Communities (n = 70; reaching over 10,000 children) were randomized to receive either counselling on infant and young child feeding or both counselling and MNPs. Government frontline health workers (FLWs) implemented and monitored program activities with support from CARE India and university partners. Monitoring data were collected over the duration of the entire program to assess program impact pathways using various checklists, which captured information about (a) attendance and training of FLWs at health subcentre meetings, (b) distribution of MNPs, (c) receipt and use of MNPs at the household level, and (d) midline mixed methods survey. At the beginning of the program, 72% of households reported receiving and 53% reported currently consuming MNPs. These numbers fell to 40% and 43% at midline, respectively. The main barrier to use by household was a lack of MNPs, due in part to infrequent FLW distribution. However, FLWs rarely reported MNP shortages at Anganwadi centres. Side effects also emerged as a barrier and were addressed through revised recommendations for MNP use. Qualitative data indicated high community acceptance of MNPs and a good understanding of the program by FLWs. The use of real-time program data allowed for recognition of key program issues and decision-making to enhance program implementation.

RESUMEN

Research demonstrates the importance of nutrition for early brain development. Few studies have examined the effectiveness of multiple micronutrient powders (MNP) on child development. This study examined the impacts of home fortification with MNP on motor and mental development, executive function and memory of children living in Bihar. This two-arm cluster-randomised effectiveness trial selected seventy health sub-centres to receive either MNP and nutrition counselling (intervention) or nutrition counselling alone (control) for 12 months. Front-line health workers delivered the intervention to all households in study communities with a child aged 6-18 months. Data were collected using cross-sectional surveys at baseline and endline by selecting households from intervention (baseline, n 2184; endline, n 2170) and control (baseline, n 2176; endline, n 2122) communities using a two-stage cluster-randomised sampling strategy. Children in the intervention group had a significantly larger improvement from baseline to endline compared with those in the control group on scores for motor and mental development (Cohen's d, motor=0·12; 95 % CI 0·03, 0·22; mental=0·15; 95 % CI 0·06, 0·25). Greater impacts of MNP on motor and mental development were observed in children from households with higher stimulation scores at baseline compared with those with lower stimulation (Cohen's d, motor=0·20 v. 0·09; mental=0·22 v. 0·14; P interaction<0·05). No significant treatment differences were seen for executive function or memory. Home fortification with MNP through the existing health infrastructure in Bihar was effective in improving motor and mental development and should be considered in combination with other child development interventions such as stimulation.

RESUMEN

Nearly two thirds of young children are anaemic in Bihar, India. Paediatric iron and folic acid syrup (IFAS) and multiple micronutrient powders (MNPs) are two evidence-based interventions to prevent anaemia. Using a randomized crossover design, we examined the acceptability of IFAS versus MNPs for children 6-23 months. In a catchment area of 2 health centres in Bihar, health front-line workers (FLWs) delivered either (a) IFAS twice weekly or (b) MNPs for 1 month followed by the other supplementation strategy for 1 month to the same families (NCT02610881). Household surveys were conducted at baseline (N = 100), 1 month after receiving the first intervention (1 month; N = 95), and 1 month after the second intervention (2 months; N = 93). Focus group discussions (10 FLWs) and in-depth interviews (20 mothers) were held at 1 and 2 months. We used chi-square and Fisher exact tests to test mothers' product preferences. Qualitative data were analysed using MaxQDA and Excel employing a thematic analysis approach. There was high adherence and acceptability for both products (>80%). There was no significant difference in preference (p < .05) on perceived benefits (39% MNPs, 40% IFAS), side effects (30% MNPs, 30% IFAS), ease of use (42% IFAS, 31% MNPs), child preference (45% IFAS, 37% MNPs), and maternal preference (44% IFAS, 34% MNPs). Mothers and FLWs indicated that the direct administration of IFAS ensured that children consumed the full dose, and MNPs intake depended on the quantity of food consumed, especially among younger children, which emphasizes the need to integrate supplementation with the promotion of optimal child feeding practices.

RESUMEN

Background: Orange-fleshed sweet potato (OFSP) improves vitamin A (VA) status of young children; research with pregnant and lactating women is limited.Objective: We examined the effectiveness of the Mama SASHA (Sweetpotato Action for Security and Health in Africa) program to improve nutrition knowledge, diets, and nutritional status of pregnant and lactating women (PLW) in Western Kenya.Methods: Eight health facilities were allocated to the Mama SASHA intervention or comparison arms. PLW in intervention facilities received enhanced nutrition counseling at health clinics, were linked with community-based maternal support groups, and received vouchers for OFSP vine cuttings. Control PLW received clinic-based nutrition counseling only. A total of 505 women in early and midpregnancy, attending their first antenatal care visit, and with no previous engagement in project activities were enrolled from the 8 facilities. Nutrition and health-seeking knowledge, food security, dietary patterns, and anthropometric measurements were collected at 4 time points at ≤9 mo postpartum. VA intakes were assessed with multipass 24-h recalls in a subsample of 206 mothers at 8-10 mo postpartum. VA status was assessed by using serum retinol-binding protein (RBP). Impacts were estimated with multilevel mixed models adjusted for clustering and differences at enrollment.Results: At enrollment, 22.9% of women had RBP <1.17 µmol/L. By 9 mo postpartum, intervention women had significantly higher intakes of VA [adjusted difference = 297.0 retinol activity equivalent (RAE) units; 95% CI: 82, 513 RAE units; P = 0.01; n = 206], greater consumption of VA-rich fruit and vegetables in the previous 7 d (difference-in-difference estimate: 0.40 d; 95% CI: 0.23, 0.56 d; P < 0.01), and a 45% reduction in the odds of RBP <1.17 µmol/L (OR: 0.55; 95% CI: 0.33, 0.92; P = 0.01).Conclusion: Promotion of OFSP to PLW through health services is a feasible strategy to improve women's nutrition knowledge, VA intakes, and maternal RBP.

RESUMEN

OBJECTIVE: Dietary practices in Kenya often fail to provide adequate nutrition during the first 1000 days of life, from conception to 2 years of age. We developed and qualitatively assessed the acceptability of easy-to-use dietary tools consisting of a marked bowl, slotted spoon and illustrated counselling card to support appropriate dietary practices during pregnancy, exclusive breast-feeding and complementary feeding of children aged 6-24 months. DESIGN: We conducted qualitative research to assess community acceptability and obtain feedback on the design of the dietary tools. SETTING: This research took place in urban and rural communities in Western Kenya. SUBJECTS: We conducted twelve focus group discussions with community members (mothers, husbands, mothers-in-law, community leaders) and five interviews with government nutritionists to assess acceptability and obtain recommendations on design and delivery of the tools. We conducted 24-28 d of user testing with fourteen pregnant women, fourteen breast-feeding women and thirty-two mothers with infants aged 6-18 months. RESULTS: Tools were positively received by communities. Mothers perceived improvements in their own and their children's food intakes including quantity, frequency, consistency and diversity. Many attributed perceived own and child's weight gain and/or increased energy to tool use. A minority reported using the bowl for other activities (n 9) or not using the bowl due to food insecurity (n 5). CONCLUSIONS: Results suggest that such tools have the potential to positively impact maternal and child dietary practices. Future work should quantitatively assess the impact on diet and nutrition outcomes and the underlying behavioural domains associated with changes.

RESUMEN

BACKGROUND: Dietary practices in India often fail to provide adequate nutrition during the first 1,000 days of life. OBJECTIVE: To explore the acceptability and utility of a low-cost and simple-to-use feeding toolkit consisting of a bowl with marks to indicate meal volume and frequency, a slotted spoon, and an illustrated counseling card to cue optimal dietary practices during the first 1,000 days. METHODS: In Samastipur District, Bihar, India, we conducted 16 focus group discussions and 8 key informant interviews to determine community acceptability and obtain feedback on design and delivery of the feeding toolkit. We conducted 14 days of user testing with 20 pregnant women, 20 breastfeeding women 0 to 6 months postpartum, and 20 mothers with infants 6 to 18 months of age. RESULTS: The toolkit, which is made of plastic, was well accepted by the community, although the communities recommended manufacturing the bowl and spoon in steel. The proportion of pregnant and breast-feeding women taking an extra portion of food per day increased from 0% to 100%, and the number of meals taken per day increased from two or three to three or four. For children 6 to 18 months of age, meal frequency, quantity of food consumed during meals, and thickness of the foods increased for all age groups. Children 6 to 8 months of age who had not yet initiated complementary feeding all initiated complementary feeding during the testing period. CONCLUSIONS: Simple feeding tools are culturally acceptable and can be appropriately used by families in Bihar, India, to improve dietary practices during the first 1,000 days of life. Research is needed to assess whether the tools promote dietary and nutritional improvements over and above counseling alone.

RESUMEN

Nutrition education and counselling (NEC) is a commonly applied strategy to improve maternal nutrition during pregnancy. However, with the exception special populations and specific diets, the effect of NEC on maternal, neonatal and child health outcomes has not been systematically reviewed. Using a modified Child Health Epidemiology Reference Group method we systematically reviewed the literature and identified and abstracted 37 articles. We conducted meta-analyses for the effect of NEC on maternal, neonatal and infant health outcomes including gestational weight gain, maternal anaemia, birthweight, low birthweight and preterm delivery. NEC significantly improved gestational weight gain by 0.45 kg, reduced the risk of anaemia in late pregnancy by 30%, increased birthweight by 105 g and lowered the risk of preterm delivery by 19%. The effect of NEC on risk of low birthweight was not significant. The effect of NEC was greater when provided with nutrition support, for example, food or micronutrient supplements or nutrition safety nets. The overall quality of the body of evidence was deemed low for all outcomes due to high heterogeneity, poor study designs and other biases. Additional well-designed research that is grounded in appropriate theories of behaviour change is needed to improve confidence in the effect of NEC. Further, cost-effectiveness research is needed to clarify the added benefit and sustainability of providing NEC with nutritional support and/or safety nets, especially in areas where food insecurity and gender bias may limit women's capacity to adhere to NEC messages.

RESUMEN

This review paper highlights mechanisms for nutritional regulation of maternal health and fetal development. Malnutrition (nutrient deficiencies or obesity) in pregnant women adversely affects their health by causing or exacerbating a plethora of problems, such as anaemia, maternal haemorrhage, insulin resistance, and hypertensive disorders (e.g. pre-eclampsia/eclampsia). Maternal malnutrition during gestation also impairs embryonic and fetal growth and development, resulting in deleterious outcomes, including intrauterine growth restriction (IUGR), low birthweight, preterm birth, and birth defects (e.g. neural tube defects and iodine deficiency disorders). IUGR and preterm birth contribute to high rates of neonatal morbidity and mortality. Major common mechanisms responsible for malnutrition-induced IUGR and preterm birth include: (i) abnormal growth and development of the placenta; (ii) impaired placental transfer of nutrients from mother to fetus; (iii) endocrine disorders; and (iv) disturbances in normal metabolic processes. Activation of a series of physiological responses leading to premature and sustained contraction of the uterine myometrium also results in preterm birth. Recent epidemiologic studies have suggested a link between IUGR and chronic metabolic disease in children and adults, and the effects of IUGR may be carried forward to subsequent generations through epigenetics. While advanced medical therapies, which are generally unavailable in low-income countries, are required to support preterm and IUGR infants, optimal nutrition during pregnancy may help ameliorate many of these problems. Future studies are necessary to develop effective nutritional interventions to enhance fetal growth and development and alleviate the burden of maternal morbidity and mortality in low- and middle-income countries.

RESUMEN

The objective of this review is to systematically examine and summarise the effects of agricultural interventions to increase household food production on the nutrition and health outcomes of women and young children and provide recommendations for future research and programming. Data from all studies meeting inclusion/exclusion criteria were abstracted into a standardised form. The quality of the evidence was assessed and graded using a modified version of the Child Health Epidemiology Reference Group adaptation of the Grading of Recommendations, Assessment, Development and Evaluation technique. Thirty-six articles, representing 27 unique projects were identified. Of these 32 and 17 reported on the health and nutrition outcomes of children and women, respectively. Although studies were too heterogeneous to conduct meta-analysis, agricultural strategies consistently reported significantly improved diet patterns and vitamin A intakes for both women and children. Although some individual studies reported significant reductions in child malnutrition, summary estimates for effects on stunting [relative risk (RR) 0.93 [95% confidence interval (CI) 0.84, 1.04]], underweight (RR 0.80 [95% CI 0.60, 1.07]) and wasting (RR 0.91 [95% CI 0.60, 1.38]) were not significant. Findings for an effect on vitamin A status, anaemia and morbidity were inconsistent. Overall the evidence base for the potential of agricultural strategies to improve the nutrition and health of women and young children is largely grounded in a limited number of highly heterogeneous, quasi-experimental studies, most of which have significant methodological limitations. While household food production strategies hold promise for improving the nutrition of women and children, the evidence base would be strengthened by additional research that is methodologically robust and adequately powered for biological and dietary indicators of nutrition.

RESUMEN

BACKGROUND: Efficacious strategies to improve maternal nutrition and subsequent maternal, neonatal, and child health exist, but their utilization and application at scale is limited. OBJECTIVE: This study explored the gaps, barriers, and opportunities for maternal nutrition policy and programming in Nigeria, a country with a disproportionate share of the global burden of maternal and child mortality METHODS: Research was conducted in three phases in four Local Government Authorities in Taraba State. Phase 1 consisted of a desk review of policies, programs, and sociodemographic and health indicators pertinent to maternal nutrition. In-depth interviews were conducted with key informants in state and local ministries of health as well as international nongovernmental organizations and community- and faith-based organizations. Phase 2 utilized in-depth interviews and focus group discussions with community leaders, health promoters, and mothers. Phase 3 consisted of key informant interviews with federal policy and program leaders in government ministries and nongovernmental organizations. RESULTS: Nutrition, especially maternal nutrition, is not prioritized and is poorly funded in both the governmental and the nongovernmental systems. Perceived weak advocacy for nutrition and its role in economic development and the lack of coordination among governmental and nongovernmental actors were said to contribute to low prioritization. Dependence on health facilities as the primary platform for delivering maternal nutrition is problematic, given severe resource constraints and perceived community barriers, including cost, distance, and poor quality of care. CONCLUSIONS: Advocacy for maternal nutrition that improves understanding of its consequences for health and economic development could hasten prioritization, coordination, and investment in maternal nutrition at the national, state, and local levels. Innovative, multisectoral strategies that move beyond facility-based platforms are needed to reduce the burden of maternal undernutrition in Northeast Nigeria.

RESUMEN

BACKGROUND: Undernutrition in women in poor countries remains prevalent and affects maternal, neonatal and child health (MNCH) outcomes. Improving MNCH outcomes requires better policies and programs that enhance women's nutrition. OBJECTIVE: The studies aimed to better understand awareness, perceptions, barriers to intervention, and policy and program priorities and approaches, through different platforms, addressing three related priority problems: anemia, intra-uterine growth retardation (IUGR), and maternal thinness and stunting (including incomplete growth with early pregnancy). METHODS: Results of a global literature review on program effectiveness, and from case studies in Ethiopia, India, and Nigeria, were synthesized. RESULTS AND CONCLUSIONS: Anemia can be reduced by iron-folate supplementation, but all aspects for successful implementation, from priority to resources to local capacity, require strengthening. For IUGR, additional interventions, offood supplementation or cash transfers, may be required for impact, plus measures to combat early pregnancy. Breaking the intergenerational cycle of women's undernutrition may also be helped by child nutrition programs. Potential interventions exist and need to be built on: iron-folate and multiple micronutrient supplementation, food fortification (including iodized salt),food supplementation and/or cash transfer programs, combatting early pregnancy, infant and young child nutrition. Potential platforms are: the health system especially antenatal care, community-based nutrition programs (presently usually child-oriented but can be extended to women), child health days, safety net programs, especially cash transfer and conditional cash transfer programs. Making these more effective requires system development and organization, capacity and training, technical guidelines and operational research, and advocacy (who takes the lead?), information, monitoring and evaluation.

RESUMEN

Background: Interventions aimed at improving dietary intake and feeding practices have alone proven insufficient for combatting stunting resulting from poor nutrition and repeated infections. Objectives: To support the development of an integrated water, sanitation, and hygiene (WASH) and nutrition, social, and behavior change strategy aimed at reducing stunting, formative research was conducted in 2 program sites in western Kenya. Methods: Twenty-nine key informant interviews were conducted with community leaders, health workers, and project staff, and 24 focus group discussions with caregivers of children under 2 y on topics related to feeding, sanitation, and hygiene behaviors. Three frameworks informed the study design and analysis of our formative research: the Capabilities, Opportunities, and Motivations model for behavior change, which identifies what needs to change in order for behavior change interventions to be effective; the Grandmother Project's Change Through Culture Approach, which values the important role of influential household and community members in producing household health; and Starr and Fornoff's approach to Theory of Change development. Results: Caregivers exhibited sufficient psychological capabilities (knowledge and skills) for many of the key maternal and infant nutrition behaviors. However, reflective motivation to perform optimal behaviors was undermined by limitations in physical and social opportunities, including limited time and competing priorities for mothers, limited accessibility and availability of diverse foods, low self-efficacy for exclusive breastfeeding, and fears of negative consequences related to specific foods and recommended practices. Conclusions: Interventions that aim to improve maternal and child diets should address the underlying social, cultural, and environmental determinants that contribute to motivations and opportunities to perform recommended practices.

RESUMEN

BACKGROUND: Global recommendations on optimal maternal and child nutrition (MCN) practices are clear; however, there is limited literature 1) exploring how roles of family members influence those practices and on 2) designing programs accordingly. Researchers using a family-systems approach in the Global South find that grandmothers often play a vital role in MCN, yet most nutrition programs narrowly target mothers, thereby potentially limiting effectiveness. OBJECTIVES: This article reports on the results of qualitative research exploring the roles and influence of family members on MCN in southern Sierra Leone, the local MCN beliefs and practices, and how those findings informed the design of a culturally appropriate program. METHODS: Focus group discussions (FGDs) were conducted with mothers, fathers, and grandmothers in 9 communities in Bonthe District, Sierra Leone. We used participatory tools to explore family members' roles and local MCN beliefs and practices. Interviews were recorded by notetakers and coded and analyzed using a content analysis approach. RESULTS: A total of 88 mothers, 125 grandmothers, and 79 fathers participated in the FGDs. All groups indicated that 1) grandmothers are the culturally designated advisors and supervisors of women on MCN issues and 2) mothers are not autonomous decision makers and are greatly influenced by grandmothers. The research identified both beneficial MCN practices and gaps between optimal and existing MCN practices-particularly related to maternal diet during pregnancy and exclusive breastfeeding for 6 mo. Research findings were used to design a grandmother-inclusive program. CONCLUSIONS: Our research showed that mothers are embedded in a family system of caring and supervision where grandmothers have primary influence on MCN practices, clearly supporting the need for grandmothers to have a central role in community MCN programs. It also points to the need for increased use of a family-systems approach in designing public health nutrition programs.

RESUMEN

Inconclusive evidence for how food environments affect health may result from an emphasis on residential neighborhood-based measures of exposure. We used an activity space approach to examine whether 1) measures of food access and 2) associations with diet and BMI differ between residential and activity space food environments among low-income African American women in Atlanta, Georgia (n = 199). Although residential and activity space environments differed across all dimensions of food access, being located farther away from 'unhealthy' outlets was associated with lower BMI in both environments. Future research should move beyond asking whether residential and activity space environments differ, toward examining if, how, and under what conditions these differences impact the estimation of health effects.

RESUMEN

BACKGROUND: Suboptimal infant and young child feeding (IYCF) practices contribute to child undernutrition. Sierra Leone Demographic and Health Survey data show that IYCF practices remain poor despite modest improvements. Recent studies have identified the role of grandmothers as critical to child nutrition; however, in Sierra Leone to date, the potential for grandmothers to influence IYCF practices has not been investigated. OBJECTIVES: We examined how an innovative grandmother-inclusive approach (GMIA) can be used to address suboptimal IYCF practices. METHODS: Using a quasi-experimental design, we compared IYCF beliefs and practices between GMIA intervention communities (receiving monthly dialogue sessions on nutrition, quarterly community praise sessions, and intergenerational forums) and comparison communities (receiving standard nutrition education) in Bum chiefdom from 2013 and 2016. The quantitative endline survey targeted 101 pregnant women, 291 women with children aged <2 y, and 219 grandmothers. Statistical analyses utilized t tests and χ2 tests to examine differences between intervention and comparison communities at endline. Multivariate regression was used to determine the intervention's effect on IYCF outcomes of interest. RESULTS: Awareness of and participation in the GMIA was high among mothers and grandmothers in intervention communities. The percentage of infants and young children aged 0-23 mo (n = 291) exclusively breastfed during the first week of life was significantly higher in the intervention group (90.2% compared with 79.4%, P = 0.01). Among infants aged 6-23 mo (n = 219), the percentage achieving minimum dietary diversity and minimum acceptable diet was significantly higher in the intervention group (77.2% compared with 51.8%, P < 0.001; and 53.8% compared with 22.6%, P < 0.001, respectively). Differences in percentages achieving minimum meal frequency (MMF) were only significant for infants aged 9-23 mo, with the intervention group achieving a higher MMF (54.6% compared with 36.9%, P = 0.02). CONCLUSIONS: Results suggest that a GMIA that recognizes grandmothers' roles and strengthens their knowledge can contribute to improved IYCF practices.

RESUMEN

BACKGROUND: Some American households experience food insecurity, where access to adequate food is limited by lack of money and other resources. As such, we implemented a free 6-month Fruit and Vegetable Prescription Program within a large urban safety-net hospital. METHODS: 32 participants completed a baseline and postintervention qualitative evaluation about food-related behaviour 6 months after study completion. Deductive codes were developed based on the key topics addressed in the interviews; inductive codes were identified from analytically reading the transcripts. Transcripts were coded in MAXQDA V.12 (Release 12.3.2). RESULTS: The information collected in the qualitative interviews highlights the many factors that affect dietary habits, including the environmental and individual influences that play a role in food choices people make. Participants expressed very positive sentiments overall about their programme participation. CONCLUSIONS: A multifaceted intervention that targets individual behaviour change, enhances nutritional knowledge and skills, and reduces socioeconomic barriers to accessing fresh produce may enhance participant knowledge and self-efficacy around healthy eating. However, socioeconomic factors remain as continual barriers to sustaining healthy eating over the long term. Ongoing efforts that address social determinants of health may be necessary to promote sustainability of behaviour change.
