RESUMO
OBJECTIVES: Improving access to healthy food in Black communities is imperative to combat intergenerational health disparities. Pregnant Black women represent an especially vulnerable population to multiple (and overlapping) sources of socioeconomic and political disenfranchisement and thus for whom maternal nutrition is crucial. This study aimed to (1) define household food environment types, (2) determine whether the distribution of community food outlets is associated with these household food environment types, and (3) determine whether the community-household food environment relationship differs by maternal education or participation in nutrition assistance programs. METHODS: Cross-sectional data for pregnant Black women in North Carolina (n = 429) come from the Mothers & Others study, an obesity-prevention randomized control trial, with linked spatial data on all community food outlets (n = 6312) in the study area in 2015. Factor analysis was used to define household food environment types. These factor scores were regressed on access metrics to community food outlets. Adjusted linear regressions tested interaction by maternal education and nutrition assistance programs. RESULTS: Four household food environment types were defined: Factor 1 (fresh fruits and vegetables (F/V), low snack), Factor 2 (canned F/V, sweet drinks), Factor 3 (dried/frozen F/V, candy), and Factor 4 (low F/V, soda). Having more convenience stores within 0.25 miles was associated with higher Factor 4 scores. No food outlets were associated with higher Factor 1 scores overall. However, SNAP or WIC participating households saw higher Factor 1 scores with increased access to supermarkets, convenience stores, and dollar stores. CONCLUSIONS: Nutrition assistance programs play an important role as buffers against unhealthy community food environments which influence household food environments and maternal nutrition.

Household gender roles influence infant and young child feeding behaviours and may contribute to suboptimal complementary feeding practices through inequitable household decision-making, intra-household food allocation and limited paternal support for resources and caregiving. In Igabi local government area of Kaduna State, Nigeria, the Alive & Thrive (A&T) initiative implemented an intervention to improve complementary feeding practices through father engagement. This study describes household gender roles among A&T participants and how they influence maternal and paternal involvement in complementary feeding. We conducted 16 focus group discussions with mothers and fathers of children aged 6-23 months in urban and rural administrative wards and analysed them using qualitative thematic analysis methods. Most mothers and fathers have traditional roles with fathers as 'providers' and 'supervisors' and mothers as 'caregivers'. Traditional normative roles of fathers limit their involvement in 'hands-on' activities, which support feeding and caring for children. Less traditional normative roles, whereby some mothers contributed to the provision of resources and some fathers contributed to caregiving, were also described by some participants and were more salient in the urban wards. In the rural wards, more fathers expressed resistance to fathers playing less traditional roles. Fathers who participated in caregiving tasks reported respect from their children, strong family relationships and had healthy home environments. Our research findings point to the need for more context-specific approaches that address prevalent gender normative roles in complementary feeding in a variety of settings.

Much literature links individual feeding styles to infant feeding practices and growth; however, parents' feeding styles are not discrete and may vary by context. We use latent profile analysis (LPA) as a person-centered approach to categorize infant feeding style patterns, test factors predicting profile membership, and examine if profiles are associated with infant feeding and weight. Additionally, we test the impact of a responsive feeding intervention on profile membership and stability. Data come from 270 African-American women and infants participating in the Mothers and Others Study, an early life obesity prevention intervention. LPA was used to categorize mothers across five constructs (laissez-faire, pressuring, restrictive, responsive and indulgent) measured at 28-weeks gestation and 3- and 15-months postpartum. Adjusted multinomial regression and regression models test the characteristics associated with profile membership and the associations between profile membership and breastfeeding and infant weight-for-age z-score (WAZ). We identified two groups (Positive and Less Responsive) prenatally, an additional group (High Controlling) at 3 months and a fourth group (High Indulgent) at 15 months. Several characteristics differed between the groups, including maternal age, income and depressive symptoms, infant sex and temperament, and treatment group. Mothers in the Positive group were more likely to breastfeed at 3 months. Infants with mothers in the High Controlling group had higher WAZ at 15 months. The intervention was associated with more Positive feeding practices at 15 months and a greater likelihood of remaining in the Positive group across the study. LPA identified profiles that are associated with maternal and infant characteristics and treatment group and with better feeding practices and growth outcomes, providing preliminary evidence that early intervention promoting more responsive feeding profiles may improve infant outcomes.

OBJECTIVE: Rapid development in low- and middle-income countries (LMIC) has led to changes in diet that have outpaced water and sanitation improvements, contributing to a dual burden of overweight and noncommunicable disease risk factors (OWT/NCD) and undernutrition and infectious disease symptoms (UND/ID) within individuals and households. Yet, little work has examined the joint impact of water and food exposures on the development of the dual burden. METHODS: We use data from Ecuador's nationally representative Encuesta Nacional de Salud y Nutrición (ENSANUT-ECU) to test whether water access and quality and diet quality and security are associated with OWT/NCD and UND/ID among 1119 children and 1582 adults in Galápagos. Adjusted multinomial and logistic models were used to test the separate and joint associations between water and food exposures and the dual burden and its components at the individual and household levels. RESULTS: The prevalence of the dual burden of OWT/NCD and UND/ID was 16% in children, 33% in adults, and 90% in households. Diet quality was associated with a higher risk of dual burden in individuals and households. Mild food insecurity was positively associated with the risk of dual burden at the household level. No water variable separately predicted the dual burden. Joint exposure to poor water access and food insecurity was associated with greater odds of dual burden in households. CONCLUSION: Our results suggest that unhealthy diets and poor water quality contribute to the dual burden at the individual and household levels. Addressing both food and water limitations is important in LMIC.

OBJECTIVES: The Galápagos provides an important setting to investigate the health impacts of a new drinking water treatment plant (DWTP) in a limited resource environment. We examine how household perceptions and practices affect the relationship between water quality and infections before and after DWTP. METHODS: Ethnographic data and self-reported infections were collected from 121 mothers and 168 children ages 2 to 10 from Isla San Cristóbal. Household tap water samples were tested for levels of fecal contamination. Community level infection rates were estimated using discharge records from the Ministry of Public Health. The effects of the new DWTP and fecal contamination levels on infections were tested using logistic and Poisson models. RESULTS: Perceptions of water quality and household practices influenced exposures to contaminated tap water. We found minimal change in drinking water sources with 85% of mothers sampled before the DWTP and 83% sampled after using bottled water, while >85% from the pooled sample used tap water for cooking and hygiene practices. The DWTP opening was associated with lower odds of fecal contamination in tap water, reported urinary infections, and community level rates of urinary and gastrointestinal infections. The household practice of recently washing the cistern contributed to higher contamination levels after the DWTP opened. CONCLUSIONS: To ensure access to clean water, public health works need to consider how household perceptions and practices influence tap water use and quality, in addition to infrastructure improvements. Exposures to contaminated tap water contribute to the burden of infectious disease in environments with inadequate water infrastructure.

BACKGROUND: Non-Hispanic black (NHB) infants are twice as likely as non-Hispanic white infants to experience rapid weight gain in the first 6 months, yet few trials have targeted this population. The current study tests the efficacy of "Mothers & Others," a home-based intervention for NHB women and their study partners versus an attention-control, on infant size and growth between birth and 15 months. METHODS: Mothers & Others was a two-group randomized controlled trial conducted between November 2013 and December 2017 with enrollment at 28-weeks pregnancy and follow-up at 3-, 6-, 9-, 12-, and 15-months postpartum. Eligible women self-identified as NHB, English-speaking, and 18-39 years. The obesity prevention group (OPG) received anticipatory guidance (AG) on responsive feeding and care practices and identified a study partner, who was encouraged to attend home visits. The injury prevention group (IPG) received AG on child safety and IPG partners only completed study assessments. The primary delivery channel for both groups was six home visits by a peer educator (PE). The planned primary outcome was mean weight-for-length z-score. Given significant differences between groups in length-for-age z-scores, infant weight-for-age z-score (WAZ) was used in the current study. A linear mixed model, using an Intent-To-Treat (ITT) data set, tested differences in WAZ trajectories between the two treatment groups. A non-ITT mixed model tested for differences by dose received. RESULTS: Approximately 1575 women were screened for eligibility and 430 were enrolled. Women were 25.7 ± 5.3 years, mostly single (72.3%), and receiving Medicaid (74.4%). OPG infants demonstrated lower WAZ than IPG infants at all time points, but differences were not statistically significant (WAZdiff = - 0.07, 95% CI - 0.40 to 0.25, p = 0.659). In non-ITT models, infants in the upper end of the WAZ distribution at birth demonstrated incremental reductions in WAZ for each home visit completed, but the overall test of the interaction was not significant (F2,170 = 1.41, p = 0.25). CONCLUSIONS: Despite rich preliminary data and a strong conceptual model, Mothers & Others did not produce significant differences in infant growth. Results suggest a positive impact of peer support in both groups. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01938118 , 09/10/2013.

A cluster randomized trial design was used to test the efficacy of a behaviour change communication intervention on the quality of the home environment and infant development at 15 months of age. Children (n = 600) in rural South India were followed from 3 through 15 months of age. The control group (C group) received the standard of care, the complementary feeding group (CF group) received recommendations on complementary foods and the responsive complementary feeding and play group (RCF&P group) received recommendations on complementary foods plus skills on responsive feeding and play. The intervention was delivered in biweekly home visits to caregivers using flip charts. At postintervention, infants (n = 521) were assessed for development (Bayley-II scales) and their home environment was assessed (Home Observation for Measurement of the Environment [HOME] scale). Cluster adjusted analysis of variance showed no significant differences at baseline. The HOME score at 15 months differed by group, F(2, 38) = 6.41, P = 0.004; the CF and RCF&P groups had higher scores than the C group. Scores on subscales 'Opportunities for Variety in Daily Stimulation' and 'Caregiver Promotion of Child Development' (CPCD) were higher for the RCF&P group than for the C and CF groups. Mental development index (MDI) scores differed by group, F(2, 37) = 3.31, P = 0.04, with the RCF&P group showing higher scores than the C group (P < 0.04); no differences were noted in psychomotor development index (PDI) scores (P = 0.48). The subscales of HOME associated with MDI at 15 months were 'CPCD' and 'Cleanliness of Child' (R2 = 0.076). 'CPCD' was also associated with PDI (R2 = 0.039). A responsive complementary feeding and play intervention delivered through home visits benefitted children's mental development and caregiving environment at 15 months.

BACKGROUND: Ecuador's cesarean delivery rate far exceeds that recommended by the Pan American Health Organization (PAHO) and the World Health Organization (WHO). Using data from three iterations of Ecuador's nationally representative, population-based survey Encuesta Nacional de Salud y Nutrición (ENSANUT/ENDEMAIN), spanning 23 years, this study examines women's mode of delivery outcomes by sociodemographic characteristics and hospital type (private, public, social security) in light of Ecuador's major health care reform over the past two decades. METHODS: Using data from the 1994, 2004, and 2012 iterations of the data set, we analyzed trends in cesarean delivery based on province, year, and institution of care. Logistic regression was used to test the odds of cesarean delivery based on hospital type, sociodemographics, and birth complications for the full sample and primiparous women. Predicted probabilities were derived from this model. RESULTS: Ecuador's cesarean rate increased from 22% in 1989 to 41% in 2012. From 2008 to 2012, the probability of cesarean delivery in private centers was significantly higher than in public centers, and from 2009 to 2012, the probability of cesarean delivery in social security centers was significantly higher than in public centers. Higher maternal age, income, education, and parity, earlier prenatal care initiation, and more prenatal visits were associated with risk for cesarean delivery. CONCLUSIONS: To decrease the adverse effects of cesarean delivery for women and their babies, cesarean delivery should be reduced. Future research should investigate how incentive structures are used and how medical indication is defined within health institutions in Ecuador.

Maternal feeding beliefs and practices have been associated with weight gain in infants and young children. Less work examines feeding beliefs prenatally or the feeding beliefs of other non-maternal caregivers (NMCs) who play important roles in infant feeding. This study validates a scale, the Infant Feeding Beliefs Questionnaire (IFBQ), to assess feeding beliefs during pregnancy among African-American women and other caregivers and tests whether the resulting belief constructs (laissez-faire, restrictive, responsive, pressuring and indulgent) are associated with maternal and NMC characteristics. Data come from 429 pregnant women and 374 NMCs including fathers, grandmothers and other family and friends enrolled in the baseline 28-week gestation visit of the Mothers and Others Study, a family-based, randomized control trial to support healthy infant feeding and prevent obesity. Confirmatory factor analysis (CFA) was used to test the fit of four a priori feeding constructs. Models were modified iteratively in mothers and then separately tested in the NMCs sample. Construct scores were created by averaging the remaining items and scale reliability was assessed. External validity was tested using bivariate and multivariable regression models. We validated five feeding belief constructs, measured through 8 sub-constructs. Reliability coefficients ranged from 0.58 for laissez faire to 0.76 for pressuring. Goodness of fit indices for CFA models indicated good fit with CFIs from 0.97 to 0.99 and RMSEA from 0.00 to 0.06. Construct scores differed significantly by depressive symptoms, obesity, education, income, and previous children in mothers and NMCs. The IFBQ may be used among mothers and NMCs to assess feeding beliefs beginning in the prenatal period, providing a tool to assess the longitudinal development of feeding beliefs and to highlight avenues for intervention on feeding practices during a critical period for behavior change.

OBJECTIVES: We conducted a study of the food environment and nutritional status among women and children living on a Galapagos Island. Anthropometric and body silhouette data give insight into body size perceptions for women and their young children. We frame our findings in the context of the nutrition transition. METHODS: A convenience sample was recruited via word-of-mouth for in-depth interviews and assessments of household food security, dietary intake, anthropometrics, and body image. Interviews took place in 2011 on San Cristobal Island, one of four inhabited islands in the Galapagos archipelago. Twenty women with children between the ages of one and six participated, all permanent residents of San Cristobal Island. RESULTS: Most women (60%) reported limited availability of fresh produce due to an unreliable food supply shipped from mainland Ecuador. Despite reported food insecurity in our sample (55%), more than half of the children (55%) experienced high dietary diversity measured by 24 h recall. Women tended to report less dietary diversity than their children, which may be linked to a stated desire to be thinner. Eighty percent of children were classified as normal weight, while 75% of women were overweight or obese. Conclusions for Practice: Results provide an initial survey of the food landscape on one Galapagos Island. By combining qualitative interviews with indicators of nutritional status, the narrative data allow an interpretation of issues of food security, dietary intakes, dietary diversity, and body size. This study forms the basis for a larger examination of these issues in the Galapagos islands.

According to global recommendations, quality diets for complementary feeding (CF) should include a diversity of foods including vitamin A-rich fruits and vegetables and sources of high-quality proteins and essential nutrients, particularly animal-source foods (ASF). A key barrier to feeding ASF surrounds beliefs that the preparation of foods of a thicker consistency may cause problems of digestion, "heaviness" or stomach problems, swallowing, and choking. The objective of this study was to explore, through systematic formative research, the acceptability, use, and feasibility of a simple technology, commercial infant food grinders, in two rural Peruvian settings where there is delayed and low consumption of complementary foods of a thick consistency, including ASF. Phase I explored the barriers, constraints, and opportunities related to the provision of foods of a thicker consistency with a focus on ASF. Phase II encompassed household behavioural trials with mothers and infants to assess the acceptability and use of the grinders in the home setting, using key concepts and messages developed from the information obtained during Phase I. The technology was highly acceptable, used by the majority of mothers (87.8%), and led to changes in cultural perceptions, facilitating increased feeding of appropriate textures (thick purees), ASF, and multimicronutrient powders. Energy, protein, and micronutrient intakes were all significantly greater after the household behavioural trials. This simple technology, paired with systematic formative research to appropriately promote its use across cultures, may have a significant effect on improving CF practices globally, particularly for young infants beginning CF at 6 months.

Infant feeding is a well-established topic of interest in obesity research, yet few studies have focused on contributions of nonmaternal caregivers (NMCs)-such as fathers, grandparents, and daycare providers-to infant feeding. Data from the Infant Care, Feeding and Risk of Obesity Project in North Carolina were used to investigate (a) which factors were associated with NMC feeding styles and (b) how NMCs' and mothers' feeding styles compared. Multivariate regression models utilizing random effects were used to analyse data from 108 NMCs who were identified by mothers as being heavily involved in infant feeding. Feeding styles were measured using the Infant Feeding Style Questionnaire. Several individual characteristics were important. Higher laissez faire-attention scores were reported by men and NMCs who lived in the same household as infant. Men reported higher indulgent-coax and indulgent-pamper scores. Perceptions of fussier infants, older infant age, and higher infant weight-for-length z-scores were also important. Mothers' and NMCs' feeding styles differed. Compared with mothers, grandparents reported lower laissez faire and indulgent-permissive scores. Fathers reported higher pressure-soothe and indulgent scores. Daycare providers reported higher restriction-diet quality and responsive satiety. Feeding styles were also predicted to change over time for all caregiver types. These findings highlight the importance of helping all caregivers develop skills that will promote optimal infant feeding outcomes. Given the paucity of research in this area, it is important to improve our understanding of what influences caregivers' feeding styles, especially among diverse populations, and how exposure to different feeding styles may shape children's obesity risk.

Before the prevention of mother-to-child transmission (PMTCT) program was widely implemented in Malawi, HIV-positive women associated exclusive breastfeeding with accelerated disease progression and felt that an HIV-positive woman could more successfully breastfeed if she had a larger body size. The relationship between breastfeeding practices and body image perceptions has not been explored in the context of the Option B+ PMTCT program, which offers lifelong antiretroviral therapy. We conducted in-depth interviews with 64 HIV-positive women in Lilongwe District, Malawi to investigate body size perceptions, how perceptions of HIV and body size influence infant feeding practices, and differences in perceptions among women in PMTCT and those lost to follow-up. Women were asked about current, preferred, and healthy body size perceptions using nine body image silhouettes of varying sizes, and vignettes about underweight and overweight HIV-positive characters were used to elicit discussion of breastfeeding practices. More than 80% of women preferred an overweight, obese, or morbidly obese silhouette, and most women (83%) believed that an obese or morbidly obese silhouette was healthy. Although nearly all women believed that an HIV-positive overweight woman could exclusively breastfeed, only about half of women thought that an HIV-positive underweight woman could exclusively breastfeed. These results suggest that perceptions of body size may influence beliefs about a woman's ability to breastfeed. Given the preference for large body sizes and the association between obesity and risk of noncommunicable diseases, we recommend that counseling and health education for HIV-positive Malawian women focus on culturally sensitive healthy weight messaging and its relationship with breastfeeding practices.

Obesity continues to be a problem in the United States. Of particular concern is the epidemic of early childhood obesity. A significant predictor of child diet is maternal diet, but little is known about this relationship during infancy. This study examined the association between maternal and infant consumption of key food groups from 6 to 18 months using data from the Infant Care, Feeding, and Risk of Obesity Study, a prospective cohort of 217 non-Hispanic black, low-income, first-time mothers. Using data from 24-hr dietary recalls collected during in-home visits at 6, 9, 12, and 18 months, we assessed longitudinal associations between mother and child intake of both energy-dense, nutrient-poor (obesogenic) food groups and fibre-, nutrient-rich food groups using random intercept logistic regression. Both mothers and their infants had high intake of sugar-sweetened beverages, desserts, and sweets and low intake of vegetables and whole grains. Infant consumption of key food groups was strongly associated with maternal consumption, suggesting the need for focused interventions to target maternal diet as a pathway to decreasing risk for the establishment of poor dietary patterns early in life.

We evaluated effects of antiretroviral (ARV) therapy and lipid-based nutrient supplements (LNSs) on iron, copper, and zinc in milk of exclusively breastfeeding HIV-infected Malawian mothers and their correlations with maternal and infant biomarkers. Human milk and blood at 2, 6, and 24 weeks post-partum and blood during pregnancy (≤30 weeks gestation) were collected from 535 mothers/infant-pairs in the Breastfeeding, Antiretrovirals, and Nutrition study. The participants received ARV, LNS, ARV and LNS, or no intervention from 0 to 28 weeks post-partum. ARVs negatively affected copper and zinc milk concentrations, but only at 2 weeks, whereas LNS had no effect. Among all treatment groups, approximately 80-90% of copper and zinc and <50% of iron concentrations met the current adequate intake for infants at 2 weeks and only 1-19% at 24 weeks. Pregnancy haemoglobin was negatively correlated with milk iron at 2 and 6 weeks (r = -.18, p < .02 for both). The associations of the milk minerals with each other were the strongest correlations observed (r = .11-.47, p < .05 for all); none were found with infant biomarkers. At 2 weeks, moderately anaemic women produced milk higher in iron when ferritin was higher or TfR lower. At 6 weeks, higher maternal α-1-acid glycoprotein and C-reactive protein were associated with higher milk minerals in mildly anaemic women. Infant TfR was lower when milk mineral concentrations were higher at 6 weeks and when mothers were moderately anaemic during pregnancy. ARV affects copper and zinc milk concentrations in early lactation, and maternal haemoglobin during pregnancy and lactation could influence the association between milk minerals and maternal and infant iron status and biomarkers of inflammation.

The postpartum period can impact diet quality and subsequently place women at greater risk for overweight or obesity. This study examined consumption of key food groups during the first 2 years postpartum among low income, non-Hispanic black, first-time mothers. Data were from the Infant Care, Feeding and Risk of Obesity Study, a cohort of 217 mother-infant dyads, followed from 3 to 18 months postpartum, collected from 2003 to 2007. At each study visit (3, 6, 9, 12, and 18 months) 24-h dietary recalls were collected. Consumption levels were compared to those recommended from the 2010 Dietary Guidelines for Americans (DGAs) for each of the following food groups: fruits, vegetables, grains, whole grains, protein foods and dairy, as well as an estimated upper limit for sugar-sweetened beverage (SSB) consumption. At each time point, mothers met recommended intake levels for grains and protein foods only. In random-intercept logistic regression models, no demographic or household characteristics were associated with a likelihood of consuming recommended levels for any of the food groups according to the DGAs. Given the low intake of fruits, vegetables, whole grains and lean protein foods and high intake of SSBs and refined grains, interventions targeting women's diet during the postpartum period are warranted.

Undernutrition and diarrhoeal disease are major causes of infant mortality. We investigated the combined roles of breastfeeding and diarrhoea on infant size in 2940 infants from the Cebu Longitudinal Health and Nutrition Survey. The study aimed to assess whether breastfeeding status modified the deficits associated with diarrhoeal disease. The primary exposures were combinations of current breastfeeding status (yes/no), the presence of diarrhoeal disease in previous week (yes/no) and a categorical survey variable (six surveys taken at bimonthly intervals when infants were 2-12 months of age). Relative weight (weight-for-length z-scores), calculated using the WHO growth standards, was estimated using sex-stratified, fixed-effects longitudinal models that also adjusted for energy from complementary foods. Post-estimation Wald tests were conducted to identify subgroup differences in relative weight. Diarrhoea was associated with reduced relative weight in both breastfed and non-breastfed infants of 6-12 months. Diarrhoea-related deficits in relative weight were significantly exacerbated in non-breastfed girls of 6 and 8 months. Importantly, in infants <6 months, being breastfed and having diarrhoea was still associated with greater relative weight compared with being non-breastfed and diarrhoea-free. Breastfeeding emerged as a strong contributor to relative weight in younger infants (<6 months) while diarrhoeal disease strongly contributed to deficits in relative weight in older infants (6-12 months). These findings underscore the importance of breastfeeding for promoting infant nutritional status in infants with or without diarrhoea from birth to 12 months.

As part of a breastfeeding promotion intervention trial in Nigeria, we provided one cell phone per group of 5-7 microcredit clients and instructed the group's cell phone recipient to share weekly breastfeeding voice and text messages with group members. We measured the feasibility and acceptability of using group cell phones by conducting semi-structured exit interviews with 195 microcredit clients whose babies were born during the intervention (target group), in-depth interviews with eight phone recipients and nine non-phone recipients, and 16 focus group discussions with other microcredit clients. Women in the target group said the group phone worked well or very well (64%). They were motivated to try the recommended practices because they trusted the information (58%) and had support from others (35%). Approximately 44% of target women reported that their groups met and shared messages at least once a week. Women in groups that met at least weekly had higher odds of exclusive breastfeeding up to 6 months (OR 5.6, 95% CI 1.6, 19.7) than women in groups that never met. In-depth interviews and focus group discussions indicated that non-phone recipients had positive feelings towards phone recipients, the group phone met participants' needs, and messages were often shared outside the group. In conclusion, group cell phone messaging to promote breastfeeding among microcredit clients is feasible and acceptable and can be part of an effective behaviour change package.

OBJECTIVE: To describe trends in country- and individual-level dual burden of malnutrition in children <5 years, and age-stratified (<2 years, ≥2 years) country-level trends, in thirty-six low- and middle-income countries (LMIC). DESIGN: Using repeated cross-sectional nationally representative data, we calculated the prevalence of malnutrition (stunting, wasting, overweight) at each survey wave, annualized rates of prevalence change for each country over time, and trends before and after 2000, for all children <5 years and separately for those ≥2 years. We examined country- (ratio of stunting to overweight) and individual-level (coexistence of stunting and overweight) dual burden in children <5 years. SETTING: Demographic and Health Surveys from thirty-six LMIC between 1990 and 2012. SUBJECTS: Children <5 years. RESULTS: Overall malnutrition prevalence decreased in children <5 years, driven by stunting decreases. Stunting rates decreased in 78 % of countries, wasting rates decreased in 58 % of countries and overweight rates increased in 36 % of countries. Rates of change differed for children ≥2 years, with children <2 years experiencing decreases in stunting in fewer countries yet increases in overweight in more countries. Countries with nearly equal prevalences of stunting and overweight in children <5 years increased from 2000 to the final year. Within a country, 0·3-10·9 % of children <5 years were stunted and overweight, and 0·6-37·8 % of stunted children <5 years were overweight. CONCLUSIONS: The dual burden exists in children <5 years on both country and individual levels, indicating a shift is needed in policies and programmes to address both sides of malnutrition. Children <2 years should be identified as a high-risk demographic.

Maternal feeding styles in infancy and early childhood are associated with children's later risk for overweight and obesity. Maternal psychosocial factors that influence feeding styles during the complementary feeding period, the time during which infants transition from a milk-based diet to one that includes solid foods and other non-milk products, have received less attention. The present study explores how maternal psychosocial factors-specifically self-esteem, parenting self-efficacy, parenting satisfaction, and depression symptoms-influence mothers' infant feeding styles at nine months of age, a time during which solid foods eating habits are being established. Participants included 160 low-income, African-American mother-infant pairs in central North Carolina who were enrolled in the Infant Care and Risk of Obesity Study. Regression models tested for associations between maternal psychosocial characteristics and pressuring and restrictive feeding styles. Models were first adjusted for maternal age, education, marital status and obesity status. To account for infant characteristics, models were then adjusted for infant weight-for-length, distress to limitations and activity level scores. Maternal self-esteem was negatively associated with pressuring to soothe. Maternal parenting self-efficacy was positively associated with restriction-diet quality. Maternal parenting satisfaction and depression symptoms were not associated with feeding styles in the final models. Focusing on strengthening maternal self-esteem and parenting self-efficacy may help to prevent the development of less desirable infant feeding styles.
