RESUMO
The overall goal of this study is to examine whether infant feeding practices differ between mothers and grandmothers in rural China. We randomly sampled 1383 caregivers of infants aged 18 to 30 months living in 351 villages across 174 townships in nationally designated poverty counties in rural areas. Results show that a high fraction of caregivers of 18- to 30-month-old children living in low-income areas of rural China do not regularly engage in positive infant feeding practices. Only 30% of children in our sample achieved adequate dietary diversity. Only 49% of children in our sample were fed meat in the day prior to survey administration. Few caregivers reported giving any vitamin supplements (such as calcium or iron supplements) to their children. We find that 33% of the children were cared for by grandmothers rather than mothers, and that grandmothers feed a less diversified diet to children than do mothers. Most (84%) caregivers rely solely on their own experiences, friends, and family members in shaping their feeding behaviors. Overall infant feeding practices are poor in rural China. Grandmothers engage in poorer feeding practices than do mothers. Grandmothers have improved their feeding practices compared to when their own children were young. Our results suggest shortcomings in the quality of infant feeding practices, at least in part due to an absence of reliable information sources.

OBJECTIVE: To evaluate the effectiveness of daily text messages as a means to improve caregivers' adherence to infant micronutrient powder (MNP) in rural Shaanxi Province of China. METHODOLOGY: 638 infants aged 6-11 months in 234 villages were involved in a cluster-randomized controlled trial (RCT). All caregivers were given free infant MNP packets at baseline in April 2013 and the follow-up survey was in July 2013. We randomly assigned 318 infants in 117 villages to treatment group (receiving daily text message) and 320 infants in the other 117 villages as control group. RESULTS: On average, daily text messages increased the number of MNP packets fed (marginal effect = 4.63; 95% confidence interval (CI) = 0.16, 9.10). The text message is more likely to increase the consumption of MNP packets if the primary caregiver was the mother (marginal effect = 12.19; 95% CI = 0.69, 23.68). Receiving the text message appears to significantly increase the likelihood of full adherence when the primary caregiver can either check (odds ratio = 2.93; 95% CI = 1.34, 6.40) or knows how to send (odds ratio = 3.26; 95% CI = 1.53, 6.97) text messages. CONCLUSION: Daily text messages improved the consumption of infant MNP packets. However, the impact was not large enough to increase the probability of caregivers being fully adherent to the feeding instruction, which is to feed 5-7 packets per week as recommended. In addition, when the mother is the caregiver and when the caregiver can check or knows how to send text messages there is greater adherence by the primary caregivers.

BACKGROUND: Anemia early in life has been associated with delayed cognitive and motor development. The WHO recommends home fortification using multiple micronutrient powders (MNPs) containing iron as a strategy to address anemia in children under two. We evaluated the effects of a program freely distributing MNP sachets to caregivers of infants in rural China. METHODS: We conducted a cluster-randomized controlled trial in Shaanxi province, enrolling all children aged 6-11 months in target villages. Following a baseline survey, investigators randomly assigned each village/cluster to a control or treatment group. In the treatment group, caregivers were instructed to give MNPs daily. Follow-up was after 6, 12, and 18 months of intervention. Primary outcomes were hemoglobin concentrations and scores on the Bayley Scales of Infant Development. RESULTS: One thousand, eight hundred and-two eligible children and their caregivers were enrolled. At baseline 48% (870) of children were anemic and 29% (529) were developmentally delayed. Six hundred and-ten children (117 villages) were assigned to the control group and 1192 children (234 villages) were assigned to the treatment group. Assignment to the treatment group was associated with an improvement in hemoglobin levels (marginal effect 1.77 g/L, 95% CI 0.017-3.520, p-value = 0.048) and cognitive development (marginal effect 2.23 points, 95% CI 0.061-4.399, p-value = 0.044) after 6 months but not thereafter. There were no significant effects on motor development. Zero effects after the first 6 months were not due to low compliance, low statistical power, or changes in feeding behavior. Hemoglobin concentrations improved in both the treatment and control groups over the course of the study; however, 22% (325) of children remained anemic at endline, and 48% (721) were cognitively delayed. CONCLUSIONS: Providing caregivers with MNP sachets modestly hastened improvement in hemoglobin levels that was occurring absent intervention; however, this improvement did not translate into improved developmental outcomes at endline.

BACKGROUND AND OBJECTIVES: Development during the first two years of life is critical and has a lasting impact on a child's health. Poor infant and child nutrition can lead to deficiencies in essential micronutrients, which may cause a weakened immune system and lasting effects on children's growth and development. Recent studies in rural Shaanxi Province found an anemia prevalence of 54.3% among rural children aged six to twelve months. While new large-scale, quantitative research has begun to catalogue the extent of child malnutrition and anemia, no effort has yet been made to look more closely at the potential reasons for rural children's nutritional deficiencies through qualitative analysis. This study aims to elucidate some of the fundamental causes of poor complementary feeding practices that may lead to anemia among children in rural Shaanxi Province, China. METHODOLOGY: We interviewed sixty caregivers participating in a large survey on child health and nutrition. We conducted three waves of interviews with children's primary caregivers in seventeen rural villages within four nationally-designated poverty counties in the southern part of Shaanxi Province. RESULTS: The qualitative analysis reveals that poor complementary feeding practices are common across our sample. Information gathered from our interviews suggests that complementary feeding practices are impeded by two constraints: absence of understanding topics related to infant health and nutrition under caregivers, as well as inadequate sources of information on these topics. Poverty does not appear to constrain child feeding practices. CONCLUSION: Our results uncover lack of proper knowledge on infant and child nutrition among rural caregivers in China. This situation causes them to fail incorporating micronutrient rich foods in their children's diet. Age-appropriate complementary feeding can stimulate children's physical and cognitive development, but in its absence it leads to iron-deficiency anemia. We suggest that steps be taken to educate caregivers to improve complementary feeding of their infants and children.

OBJECTIVES: To test whether text message reminders sent to caregivers improve the effectiveness of a home micronutrient fortification program in western China. METHODS: We carried out a cluster-randomized controlled trial in 351 villages (clusters) in Shaanxi Province in 2013 and 2014, enrolling children aged 6 to 12 months. We randomly assigned each village to 1 of 3 groups: free delivery group, text messaging group, or control group. We collected information on compliance with treatments and hemoglobin concentrations from all children at baseline and 6-month follow-up. We estimated the intent-to-treat effects on compliance and child anemia using a logistic regression model. RESULTS: There were 1393 eligible children. We found that assignment to the text messaging group led to an increase in full compliance (marginal effect = 0.10; 95% confidence interval [CI] = 0.03, 0.16) compared with the free delivery group and decrease in the rate of anemia at end line relative to the control group (marginal effect = -0.07; 95% CI = -0.12, -0.01), but not relative to the free delivery group (marginal effect = -0.03; 95% CI = -0.09, 0.03). CONCLUSIONS: Text messages improved compliance of caregivers to a home fortification program and children's nutrition.

Anemia is one of the most prevalent public health problems among infants and iron deficiency anemia has been related to many adverse consequences. The overall goal of this study is to examine the prevalence of anemia among infants in poor rural China and to identify correlates of anemia. In April 2013, we randomly sampled 948 infants aged 6-11 months living in 351 villages across 174 townships in nationally-designated poverty counties in rural areas of southern Shaanxi Province, China. Infants were administered a finger prick blood test for hemoglobin (Hb). Anthropometric measurement and household survey of demographic characteristics and feeding practices were conducted in the survey. We found that 54.3% of 6-11 month old infants in poor rural China are anemic, and 24.3% of sample infants suffer from moderate or severe anemia. We find that children still breastfed over 6 months of age had lower Hb concentrations and higher anemia prevalence than their non-breastfeeding counterparts (p < 0.01), and that children who had ever been formula-fed had significantly higher Hb concentrations and lower anemia prevalence than their non-formula-fed counterparts (p < 0.01). The results suggest the importance of iron supplementation or home fortification while breastfeeding.

Despite growing wealth and a strengthening government commitment to improve livelihoods and welfare, many students across rural China have inadequate access to micronutrient-rich diets. Poor diets can lead to nutritional problems, such as iron-deficiency anemia, that can adversely affect health, attention, learning, and mental health. The overall goal of this paper is to assess the impact of multiple micronutrient supplementation (MMS) on anemia and anxiety among students in poor areas of rural China. To achieve this goal, we conducted a randomized controlled trial in 54 randomly chosen elementary schools in 8 of the poorest counties in Shaanxi Province in Northwest China. Study participants were 2730 fourth-grade students, mostly aged 10-12 y. Schools were randomly assigned to 1 of 2 groups: a control group that received no intervention and an intervention group that received a daily MMS with 5 mg of iron (ferrous sulfate) for 5 mo. Our primary outcome measures were hemoglobin (Hb) concentrations (assessed by HemoCue 201+ technology), anemia prevalence (defined as Hb) concentrations ≤120 g/L), and anxiety (using a written mental health test). The results showed that 42.4% of students were anemic at baseline. The Hb concentration was 121.7 ± 10.7 g/L in the treatment group and 123.4 ± 11.4 g/L in the control group. MMS increased Hb concentrations by 1.7 g/L ± 0.15 and reduced anemia rates by 7.0 percentage points (P < 0.05). Anxiety was reduced by 0.30 SDs (P < 0.01). MMS reduced both anemia and anxiety. Our results should encourage further research on the linkages between nutrition and mental health in a development context.
