Infant and Young Child Feeding Knowledge among Caregivers of Children Aged between 0 and 24 Months in Seshego Township, Limpopo Province, South Africa. Healthcare (Basel) 2023; 11:healthcare11071044. [PMID: 37046971 PMCID: PMC10094686 DOI: 10.3390/healthcare11071044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 03/26/2023] [Accepted: 04/03/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND Appropriate infant and young child feeding (IYCF) involves the initiation of breastfeeding within an hour of delivery, exclusive breastfeeding for 6 months, introduction of complementary feeding at 6 months while continuing breastfeeding for 2 years or beyond. Adequate IYCF knowledge among caregivers is associated with improved practices, lowers risk of kids developing malnutrition, infection, morbidity, and mortality. Early introduction of solid foods, mixed feeding, inadequate breastfeeding, and complementary feeding are all prevalent in South Africa. These are related to caregivers' lack of IYCF knowledge. Hence, this study aims to determine the IYCF knowledge level of caregivers of children under 24 months in the semiurban Seshego Township, South Africa. METHODOLOGY Quantitative and cross-sectional design was applied. A total of 86 caregivers were selected using simple random sampling, which is representative of a target population of 110. Structured questionnaire was utilised to gather data, and analysed through statistical software, using descriptive and inferential statistics. Chi-square test was used to calculate associations at 95% confidence interval, where a p-value of < 0.05 was considered statistically significant. RESULTS Findings show that 67% of participants had good IYCF knowledge (a score of 81 to 100%) and there was a significant relationship between knowledge and education (p = 0.001). Moreover, 40.7% did not know that exclusive breastfeeding should be up to 6 months, and 90% mentioned that breastmilk protects the child against diseases. Most participants (82.6%) know that complementary feeding should be introduced at 6 months with continuation of breastfeeding. CONCLUSIONS Caregivers know that breastfeeding should begin immediately after birth, and that it protects against diseases. Moreover, they know that solid food should be introduced at 6 months. However, there is still a need to strengthen IYCF education, particularly on exclusive breastfeeding. Interventions to improve IYCF knowledge should be intertwined with improving educational and health literacy on breastfeeding and complementary feeding.

Abstract
Linear growth failure (stunting) in childhood is the most prevalent form of undernutrition globally. The debate continues as to whether children who become stunted before age 24 months can catch up in growth and cognitive functions later in their lives. The potentially irreparable physical and neurocognitive damage that accompanies stunted growth is a major obstacle to human development. This review aims at evaluation and summarizing the published research covering the different aspects of stunting from childhood to adulthood.

Abstract
BACKGROUND Vitamin D is a secosteroid hormone that is important for its role in calcium homeostasis to maintain skeletal health. Linear growth faltering and stunting remain pervasive indicators of poor nutrition status among infants and children under five years of age around the world, and low vitamin D status has been linked to poor growth. However, existing evidence on the effects of vitamin D supplementation on linear growth and other health outcomes among infants and children under five years of age has not been systematically reviewed. OBJECTIVES To assess effects of oral vitamin D supplementation on linear growth and other health outcomes among infants and children under five years of age. SEARCH METHODS In December 2019, we searched CENTRAL, PubMed, Embase, 14 other electronic databases, and two trials registries. We also searched the reference lists of relevant publications for any relevant trials, and we contacted key organisations and authors to obtain information on relevant ongoing and unpublished trials. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs assessing the effects of oral vitamin D supplementation, with or without other micronutrients, compared to no intervention, placebo, a lower dose of vitamin D, or the same micronutrients alone (and not vitamin D) in infants and children under five years of age who lived in any country. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. MAIN RESULTS Out of 75 studies (187 reports; 12,122 participants) included in the qualitative analysis, 64 studies (169 reports; 10,854 participants) contributed data on our outcomes of interest for meta-analysis. A majority of included studies were conducted in India, USA, and Canada. Two studies reported for-profit funding, two were categorised as receiving mixed funding (non-profit and for-profit), five reported that they received no funding, 26 did not disclose funding sources, and the remaining studies were funded by non-profit funding. Certainty of evidence varied between high and very low across outcomes (all measured at endpoint) for each comparison. Vitamin D supplementation versus placebo or no intervention (31 studies) Compared to placebo or no intervention, vitamin D supplementation (at doses 200 to 2000 IU daily; or up to 300,000 IU bolus at enrolment) may make little to no difference in linear growth (measured length/height in cm) among children under five years of age (mean difference (MD) 0.66, 95% confidence interval (CI) -0.37 to 1.68; 3 studies, 240 participants; low-certainty evidence); probably improves length/height-for-age z-score (L/HAZ) (MD 0.11, 95% CI 0.001 to 0.22; 1 study, 1258 participants; moderate-certainty evidence); and probably makes little to no difference in stunting (risk ratio (RR) 0.90, 95% CI 0.80 to 1.01; 1 study, 1247 participants; moderate-certainty evidence). In terms of adverse events, vitamin D supplementation results in little to no difference in developing hypercalciuria compared to placebo (RR 2.03, 95% CI 0.28 to 14.67; 2 studies, 68 participants; high-certainty evidence). It is uncertain whether vitamin D supplementation impacts the development of hypercalcaemia as the certainty of evidence was very low (RR 0.82, 95% CI 0.35 to 1.90; 2 studies, 367 participants). Vitamin D supplementation (higher dose) versus vitamin D (lower dose) (34 studies) Compared to a lower dose of vitamin D (100 to 1000 IU daily; or up to 300,000 IU bolus at enrolment), higher-dose vitamin D supplementation (200 to 6000 IU daily; or up to 600,000 IU bolus at enrolment) may have little to no effect on linear growth, but we are uncertain about this result (MD 1.00, 95% CI -2.22 to 0.21; 5 studies, 283 participants), and it may make little to no difference in L/HAZ (MD 0.40, 95% CI -0.06 to 0.86; 2 studies, 105 participants; low-certainty evidence). No studies evaluated stunting. As regards adverse events, higher-dose vitamin D supplementation may make little to no difference in developing hypercalciuria (RR 1.16, 95% CI 1.00 to 1.35; 6 studies, 554 participants; low-certainty evidence) or in hypercalcaemia (RR 1.39, 95% CI 0.89 to 2.18; 5 studies, 986 participants; low-certainty evidence) compared to lower-dose vitamin D supplementation. Vitamin D supplementation (higher dose) + micronutrient(s) versus vitamin D (lower dose) + micronutrient(s) (9 studies) Supplementation with a higher dose of vitamin D (400 to 2000 IU daily, or up to 300,000 IU bolus at enrolment) plus micronutrients, compared to a lower dose (200 to 2000 IU daily, or up to 90,000 IU bolus at enrolment) of vitamin D with the same micronutrients, probably makes little to no difference in linear growth (MD 0.60, 95% CI -3.33 to 4.53; 1 study, 25 participants; moderate-certainty evidence). No studies evaluated L/HAZ or stunting. In terms of adverse events, higher-dose vitamin D supplementation with micronutrients, compared to lower-dose vitamin D with the same micronutrients, may make little to no difference in developing hypercalciuria (RR 1.00, 95% CI 0.06 to 15.48; 1 study, 86 participants; low-certainty evidence) and probably makes little to no difference in developing hypercalcaemia (RR 1.00, 95% CI 0.90, 1.11; 2 studies, 126 participants; moderate-certainty evidence). Four studies measured hyperphosphataemia and three studies measured kidney stones, but they reported no occurrences and therefore were not included in the comparison for these outcomes. AUTHORS' CONCLUSIONS Evidence suggests that oral vitamin D supplementation may result in little to no difference in linear growth, stunting, hypercalciuria, or hypercalcaemia, compared to placebo or no intervention, but may result in a slight increase in length/height-for-age z-score (L/HAZ). Additionally, evidence suggests that compared to lower doses of vitamin D, with or without micronutrients, vitamin D supplementation may result in little to no difference in linear growth, L/HAZ, stunting, hypercalciuria, or hypercalcaemia. Small sample sizes, substantial heterogeneity in terms of population and intervention parameters, and high risk of bias across many of the included studies limit our ability to confirm with any certainty the effects of vitamin D on our outcomes. Larger, well-designed studies of long duration (several months to years) are recommended to confirm whether or not oral vitamin D supplementation may impact linear growth in children under five years of age, among both those who are healthy and those with underlying infectious or non-communicable health conditions.

Cochrane Database Syst Rev 2019; 2019:CD009902. [PMID: 31684687 PMCID: PMC6814158 DOI: 10.1002/14651858.cd009902.pub2] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/01/2023]
Abstract
BACKGROUND Rice fortification with vitamins and minerals has the potential to increase the nutrition in rice-consuming countries where micronutrient deficiencies exist. Globally, 490 million metric tonnes of rice are consumed annually. It is the dominant staple food crop of around three billion people. OBJECTIVES To determine the benefits and harms of rice fortification with vitamins and minerals (iron, vitamin A, zinc or folic acid) on micronutrient status and health-related outcomes in the general population. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, and 16 other databases all up to 10 December 2018. We searched ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform (ICTRP) on 10 December 2018. SELECTION CRITERIA We included randomised and quasi-randomised trials (with either individual or cluster randomisation) and controlled before-and-after studies. Participants were populations older than two years of age (including pregnant women) from any country. The intervention was rice fortified with at least one micronutrient or a combination of several micronutrients (iron, folic acid, zinc, vitamin A or other vitamins and minerals) compared with unfortified rice or no intervention. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two review authors independently screened studies and extracted data. MAIN RESULTS We included 17 studies (10,483 participants) and identified two ongoing studies. Twelve included studies were randomised-controlled trials (RCTs), with 2238 participants after adjusting for clustering in two cluster-RCTs, and five were non-randomised studies (NRS) with four controlled before-and-after studies and one cross-sectional study with a control (8245 participants). Four studies were conducted in India, three in Thailand, two in the Philippines, two in Brazil, one each in Bangladesh, Burundi, Cambodia, Indonesia, Mexico and the USA. Two studies involved non-pregnant, non-lactating women and 10 involved pre-school or school-age children. All 17 studies reported fortification with iron. Of these, six studies fortified rice with iron only; 11 studies had other micronutrients added (iron, zinc and vitamin A, and folic acid). One study had one arm each with vitamin A alone and carotenoid alone. Elemental iron content ranged from 0.2 to 112.8 mg/100 g uncooked rice given for a period varying from two weeks to 48 months. Thirteen studies did not clearly describe either sequence generation or allocation concealment. Eleven studies had a low attrition rate. There was no indication of selective reporting in the studies. We considered two RCTs at low overall risk of bias and 10 at high overall risk of bias. One RCT was at high or unclear risk of bias for most of the domains. All controlled before-and-after studies had a high risk or unclear risk of bias in most domains. The included studies were funded by Government, private and non-governmental organisations, along with other academic institutions. The source of funding does not appear to have altered the results. We used the NRS in the qualitative synthesis but we excluded them from the quantitative analysis and review conclusions since they provided mostly contextual information and limited quantitative information. Rice fortified with iron alone or in combination with other micronutrients versus unfortified rice (no micronutrients added) Fortification of rice with iron (alone or in combination with other micronutrients) may make little or no difference in the risk of having anaemia (risk ratio (RR) 0.72, 95% confidence interval (CI) 0.54 to 0.97; I2 = 74%; 7 studies, 1634 participants; low-certainty evidence) and may reduce the risk of iron deficiency (RR 0.66, 95% CI 0.51 to 0.84; 8 studies, 1733 participants; low-certainty evidence). Rice fortification may increase mean haemoglobin (mean difference (MD) 1.83, 95% CI 0.66 to 3.00; I2 = 54%; 11 studies, 2163 participants; low-certainty evidence) and it may make little or no difference to vitamin A deficiency (with vitamin A as one of the micronutrients in the fortification arm) (RR 0.68, 95% CI 0.36 to 1.29; I2 = 37%; 4 studies, 927 participants; low-certainty evidence). One study reported that fortification of rice (with folic acid as one of the micronutrients) may improve serum or plasma folate (nmol/L) (MD 4.30, 95% CI 2.00 to 6.60; 215 participants; low-certainty evidence). One study reported that fortification of rice with iron alone or with other micronutrients may slightly increase hookworm infection (RR 1.78, 95% CI 1.18 to 2.70; 785 participants; low-certainty evidence). We are uncertain about the effect of fortified rice on diarrhoea (RR 3.52, 95% CI 0.18 to 67.39; 1 study, 258 participants; very low-certainty evidence). Rice fortified with vitamin A alone or in combination with other micronutrients versus unfortified rice (no micronutrients added) One study had one arm providing fortified rice with vitamin A only versus unfortified rice. Fortification of rice with vitamin A (in combination with other micronutrients) may increase mean haemoglobin (MD 10.00, 95% CI 8.79 to 11.21; 1 study, 74 participants; low-certainty evidence). Rice fortified with vitamin A may slightly improve serum retinol concentration (MD 0.17, 95% CI 0.13 to 0.21; 1 study, 74 participants; low-certainty evidence). No studies contributed data to the comparisons of rice fortification versus no intervention. The studies involving folic acid and zinc also involved iron in the fortification arms and hence we reported them as part of the first comparison. AUTHORS' CONCLUSIONS Fortification of rice with iron alone or in combination with other micronutrients may make little or no difference in the risk of having anaemia or presenting iron deficiency and we are uncertain about an increase in mean haemoglobin concentrations in the general population older than 2 years of age. Fortification of rice with iron and other micronutrients such as vitamin A or folic acid may make little or no difference in the risk of having vitamin A deficiency or on the serum folate concentration. There is limited evidence on any adverse effects of rice fortification.

Birth size and early pneumonia predict linear growth among HIV-exposed uninfected infants. MATERNAL AND CHILD NUTRITION 2019; 15:e12861. [PMID: 31222958 DOI: 10.1111/mcn.12861] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 06/05/2019] [Accepted: 06/06/2019] [Indexed: 12/27/2022]
Abstract
Stunting remains a global health priority, particularly in sub-Saharan Africa. Identifying determinants of linear growth in HIV-exposed uninfected (HEU) infants can inform interventions to prevent stunting in this vulnerable population. HIV-infected mothers and their uninfected infants were followed monthly from pregnancy to 12-month post-partum in Nairobi, Kenya. Mixed-effects models estimated the change in length-for-age z-score (LAZ) from birth to 12 months by environmental, maternal, and infant characteristics. Multivariable models included factors univariately associated with LAZ. Among 372 HEU infants, mean LAZ decreased from -0.54 (95% confidence interval [CI] [-0.67, -0.41]) to -1.09 (95% CI [-1.23, -0.96]) between 0 and 12 months. Declines in LAZ were associated with crowding (≥2 persons per room; adjusted difference [AD] in 0-12 month change: -0.46; 95% CI [-0.87, -0.05]), use of a pit latrine versus a flush toilet (AD: -0.29; 95% CI [-0.57, -0.02]), and early infant pneumonia (AD: -1.14; 95% CI [-1.99, -0.29]). Infants with low birthweight (<2,500 g; AD: 1.08; 95% CI [0.40, 1.76]) and birth stunting (AD: 1.11; 95% CI [0.45, 1.78]) experienced improved linear growth. By 12 months of age, 46 infants were stunted, of whom 11 (24%) were stunted at birth. Of the 34 infants stunted at birth with an available 12-month LAZ, 68% were not stunted at 12 months. Some low birthweight and birth-stunted HEU infants had significant linear growth recovery. Early infant pneumonia and household environment predicted poor linear growth and may identify a subgroup of HEU infants for whom to provide growth-promoting interventions.

Abstract
BACKGROUND Undernutrition and poor cognitive development affect many children in developing countries. Good nutrition and health care are essential for optimal child development and growth. OBJECTIVES We assessed the impact of peer counseling combined with psychosocial stimulation on feeding practices and child growth and development in slums in Bangladesh. METHODS We performed a community-based cluster randomized controlled trial in selected slums; 350 mother-infant pairs were allocated to receive peer counseling on feeding practices plus psychosocial stimulation (PC + PCS; n = 175) or usual health messages (control; n = 175) using restricted randomization. Data were collected at enrollment and 1, 3, 5, 7, 9, and 12 mo after delivery. We collected data on infant and young child feeding practices and anthropometric measurements from birth until 12 mo to assess the main outcomes, including feeding practices and growth. We used the Bayley Scale III at 12 mo to assess child development. The effects of the PC + PCS intervention were assessed by using regression models. RESULTS More mothers in the PC + PCS group than in the control group reported early initiation of breastfeeding (in the first hour: 89% compared with 78%, respectively; P < 0.05) and exclusive breastfeeding at 5 mo (73% compared with 27%, respectively; P < 0.001). Peer counseling had positively impacted infant length gain at 12 mo (P < 0.005). Children in the PC + PCS group were found to be more socially and emotionally active compared with controls at 12 mo (standardized score: 0.165 compared with -0.219, respectively; P < 0.05). CONCLUSION Combining peer counseling with psychosocial stimulation had positive effects on infant feeding practices and growth at 12 mo and on the social-emotional development of young children. This trial was registered at clinicaltrial.gov as NCT03040375.

Abstract
Postnatal depression (PND) has been a common depressive mental disorder among the mothers in a low-income country like Bangladesh where stunting, underweight and wasting are prevalent among infants. The present prospective cohort study was carried out among 297 non-depressed and 103 depressed mothers (ages 18-36 years) to find the association between post natal depression and growth of infants. Data were collected by face to face interview through semi-structured questionnaires and anthropometric measurements were taken with proper anthropometric techniques and calibrated instruments. Postnatal depression was assessed by the Edinburgh Postnatal Depression Scale and infants' physical growth was assessed by Z score of weight, length and Mid-Upper Arm Circumference (MUAC). The overall prevalence of post natal depression was found 22% [95% CI, 21.71-30.29]. Infants of depressed mothers were found iller in comparison with the infants of non-depressed mothers (p < 0.001) which could result in growth retardation of infants. According to the MUAC level, infants of depressed mothers were more at risk of malnutrition (p < 0.001). Early detection of postpartum depression, implementation of interventions, prevention or treatment of maternal depressive disorders and effective strategies will not only ameliorate the impact of PND among mothers but also facilitates infant growth.

Abstract
OBJECTIVE We aimed to determine nutritional status and related factors among schoolchildren in Çorum, Central Anatolia, Turkey. DESIGN Schoolchildren's height and weight were measured to calculate BMI and BMI Z-scores. Height, weight and BMI Z-scores were analysed and nutritional status classified according to the WHO. SETTING Central Anatolia, Turkey.ParticipantsSchoolchildren aged 5-17 years (n 1684) participated in study. RESULTS Of children, 4·2% were stunted, 6·9% thin, 13·8% overweight and 6·6% were obese. Proportions of stunting, thinness and overweight/obesity were significantly higher in children aged >10 years (78·6, 75·0 and 64·9%, respectively) than in those aged ≤10 years (21·4, 25·0 and 35·1%, respectively; all P <0·001). Median (range) birth weight and breast-feeding duration in children with stunting (2750 (1400-3600)g; 10 (0-36) months) were significantly lower and shorter, respectively, than those of normal height (3200 (750-5500)g; 15 (0-72) months) and tall children (3500 (2500-4900)g; 18 (0-36) months; P <0·001, <0·001, 0·011 and 0·016, respectively). The same relationship was observed in thin children (3000 (1000-4500)g; 12 (0-36) months) compared with normal-weight (3200 (750-5500)g; 15 (0-72) months) and overweight/obese children (3300 (1200-5500)g; 16 (0-48) months; P=0·026, <0·001, 0·045 and 0·011, respectively). CONCLUSIONS Overweight and obesity are health problems that must be addressed in schoolchildren. Adolescents also have a risk of double malnutrition. Promoting normal birth weight and encouraging long duration of breast-feeding are important to support normal growth in children.

Abstract
BACKGROUND Depression is the leading cause of disease-related disability in women and adversely affects the health and well-being of mothers and their children. Studies have shown maternal depression as a risk factor for poor infant growth. Little is known about the situation in Sub-Saharan Africa. The aim of our study was to examine the association between maternal depression and severe acute malnutrition in Kenyan children aged 6-60 months. METHODS A matched case-control study was conducted in general paediatric wards at the Kenyatta National Hospital. The cases were children admitted with severe acute malnutrition as determined by WHO criteria. The controls were age and sex-matched children with normal weight admitted in the same wards with acute ailments. Mothers of the cases and controls were assessed for depression using the PHQ-9 questionnaire. Child anthropometric and maternal demographic data were captured. Logistic regression analyses were used to compare the odds of maternal depression in cases and controls, taking into account other factors associated with child malnutrition status. RESULTS The prevalence of moderate to severe depression among mothers of malnourished children was high (64.1%) compared to mothers of normal weight children (5.1%). In multivariate analyses, the odds of maternal depression was markedly higher in cases than in controls (adjusted OR = 53.5, 95% CI = 8.5-338.3), as was the odds of having very low income (adjusted OR = 77.6 95% CI = 5.8-1033.2). CONCLUSIONS Kenyan mothers whose children are hospitalized with malnutrition were shown in this study to carry a significant mental health burden. We strongly recommend formation of self-help groups that offer social support, counseling, strategies to address food insecurity, and economic empowerment skills for mothers of children hospitalized for malnourishment.

Abstract
Background To understand the full impact of stunting in childhood it is important to consider the long-run effects of undernutrition on the outcomes of adults who were affected in early life. Focusing on the costs of stunting provides a means of evaluating the economic case for investing in childhood nutrition. Methods We review the literature on the association between stunting and undernutrition in childhood and economic outcomes in adulthood. At the national level, we also evaluate the evidence linking stunting to economic growth. Throughout, we consider randomized controlled trials (RCTs), quasi-experimental approaches and observational studies. Results Long-run evaluations of two randomized nutrition interventions indicate substantial returns to the programmes (a 25% and 46% increase in wages for those affected as children, respectively). Cost-benefit analyses of nutrition interventions using calibrated return estimates report a median return of 17.9:1 per child. Assessing the wage premium associated with adult height, we find that a 1-cm increase in stature is associated with a 4% increase in wages for men and a 6% increase in wages for women in our preferred set of studies which attempt to address unobserved confounding and measurement error. In contrast, the evidence on the association between economic growth and stunting is mixed. Conclusions Countries with high rates of stunting, such as those in South Asia and sub-Saharan Africa, should scale up policies and programmes aiming to reduce child undernutrition as cost-beneficial investments that expand the economic opportunities of their children, better allowing them and their countries to reach their full potential. However, economic growth as a policy will only be effective at reducing the prevalence of stunting when increases in national income are directed at improving the diets of children, addressing gender inequalities and strengthening the status of women, improving sanitation and reducing poverty and inequities.

Abstract
Stunting is a measure of overall nutritional status and is a major public health concern because of its association with child mortality and morbidity and later adult performance. This study examined the effects of pregnancy events, birth characteristics and infant risk exposure on stunting at age 2 years. The study, established in 1990 in Soweto, an urban South African township, included 1098 mother-infant pairs enroled in the Birth to Twenty Plus longitudinal birth cohort study. In total, 22% of children were stunted at age 2 years, with males at greater risk than females [24.8 v. 19.4%, odds ratio (OR)=1.38; 95% confidence interval (CI): 1.03, 1.83]. In unadjusted analysis, male sex, household socio-economic status (SES), overcrowding, maternal age, maternal education, single motherhood, ethnicity, birth weight, gestational age and duration of infant breastfeeding were all significantly associated with stunting. In multivariable analysis, higher birth weight was protective against stunting for both sexes. Higher maternal education was protective for females only (adjusted odds ratio (AOR)=0.35; 95% CI: 0.14, 0.87), whereas wealthier household SES protected males (AOR for richest SES group=0.39; 95% CI: 0.16, 0.92). In this and other similar settings, current stunting prevention efforts focussing on primarily providing targeted proximal interventions, such as food supplements, risk undermining the critical importance of addressing key distal determinants of stunting such as SES and maternal education.

Abstract
BACKGROUND The effectiveness of prenatal care for improving birth and subsequent child outcomes in low-income countries remains controversial, with much of the evidence to date coming from high-income countries and focused on early-life outcomes. We examined associations between prenatal care visits and birth weight, height-for-age at 24 months and attained schooling in four low- and middle-income countries. METHODS We pooled data from prospective birth-cohort studies from Brazil, Guatemala, Philippines and South Africa. We created a prenatal care utilization index based on the number and timing of prenatal visits. Associations were examined between this index and birth weight, height-for-age at 24 months, and highest attained schooling grade until adulthood. RESULTS Among 7203 individuals in the analysis, 68.9% (Philippines) to 96.7% (South Africa) had at least one prenatal care visit, with most having at least four visits. Over 40% of Brazilians and Guatemalans had their first prenatal visit in the first trimester, but fewer Filipinos (13.9%) and South Africans (19.8%) did so. Prenatal care utilization was not significantly associated with birth weight (p>0.05 in pooled data). Each unit increase in the prenatal care utilization index was associated with 0.09 (95% CI 0.04 to 0.15) higher height-for-age z-score at 24 months and with 0.26 (95% CI 0.17 to 0.35) higher schooling grades attained. Although there was some heterogeneity and greater imprecision across sites, the results were qualitatively similar among the four different populations. CONCLUSIONS While not related to birth weight, prenatal care utilization was associated with important outcomes later in life, specifically higher height-for-age at 24 months and higher attained school grades. These results suggest the relevance of prenatal care visits for human capital outcomes important over the lifecycle.

Abstract
Background Informal settlements are common throughout the developing world. In Peru, land occupations, commonly “invasions” in Spanish, are a means by which the extremely poor attempt to obtain access to land. Here, we examine difference in child health between two communities in the Peruvian Amazon, one well-established and one newly formed by ‘invasion’, as captured incidentally by a prospective epidemiological cohort study. Methods Between 2002 and 2006 a study designed to describe the epidemiology of pediatric enteric infections and child growth in a community-based setting enrolled 442 children in Santa Clara de Nanay, a community adjacent to the city of Iquitos, in Loreto, Peru. In early 2003, a land occupation, commonly called an “invasion” in Spanish, was organized by members of the Santa Clara community, and approximately 20 % of participating study families began occupying privately owned agricultural land adjacent to Santa Clara, thus forming the new community of La Union. Results Parents in families that chose to invade reported less education than parents in families that chose not to. Children in the new community experienced a higher incidence of diarrheal disease and non-specific fevers, although fewer helminth infections, than children who remained in the established community. At the time of the invasion, there were no differences in anthropometric status between the two groups; however children in the new community experienced greater progressive growth faltering over the course of the longitudinal study. Conclusions Growth faltering in early childhood represents an enduring loss of human potential. Therefore, our data suggests the human cost of land invasion may be disproportionately borne by the youngest individuals. Innovative policy strategies may be needed to protect this vulnerable group.

Abstract
BACKGROUND Tackling severe acute malnutrition (SAM) is a global health priority. Heightened risk of non-communicable diseases (NCD) in children exposed to SAM at around 2 years of age is plausible in view of previously described consequences of other early nutritional insults. By applying developmental origins of health and disease (DOHaD) theory to this group, we aimed to explore the long-term effects of SAM. METHODS We followed up 352 Malawian children (median age 9·3 years) who were still alive following SAM inpatient treatment between July 12, 2006, and March 7, 2007, (median age 24 months) and compared them with 217 sibling controls and 184 age-and-sex matched community controls. Our outcomes of interest were anthropometry, body composition, lung function, physical capacity (hand grip, step test, and physical activity), and blood markers of NCD risk. For comparisons of all outcomes, we used multivariable linear regression, adjusted for age, sex, HIV status, and socioeconomic status. We also adjusted for puberty in the body composition regression model. FINDINGS Compared with controls, children who had survived SAM had lower height-for-age Z scores (adjusted difference vs community controls 0·4, 95% CI 0·6 to 0·2, p=0·001; adjusted difference vs sibling controls 0·2, 0·0 to 0·4, p=0·04), although they showed evidence of catch-up growth. These children also had shorter leg length (adjusted difference vs community controls 2·0 cm, 1·0 to 3·0, p<0·0001; adjusted difference vs sibling controls 1·4 cm, 0·5 to 2·3, p=0·002), smaller mid-upper arm circumference (adjusted difference vs community controls 5·6 mm, 1·9 to 9·4, p=0·001; adjusted difference vs sibling controls 5·7 mm, 2·3 to 9·1, p=0·02), calf circumference (adjusted difference vs community controls 0·49 cm, 0·1 to 0·9, p=0·01; adjusted difference vs sibling controls 0·62 cm, 0·2 to 1·0, p=0·001), and hip circumference (adjusted difference vs community controls 1·56 cm, 0·5 to 2·7, p=0·01; adjusted difference vs sibling controls 1·83 cm, 0·8 to 2·8, p<0·0001), and less lean mass (adjusted difference vs community controls -24·5, -43 to -5·5, p=0·01; adjusted difference vs sibling controls -11·5, -29 to -6, p=0·19) than did either sibling or community controls. Survivors of SAM had functional deficits consisting of weaker hand grip (adjusted difference vs community controls -1·7 kg, 95% CI -2·4 to -0·9, p<0·0001; adjusted difference vs sibling controls 1·01 kg, 0·3 to 1·7, p=0·005,)) and fewer minutes completed of an exercise test (sibling odds ratio [OR] 1·59, 95% CI 1·0 to 2·5, p=0·04; community OR 1·59, 95% CI 1·0 to 2·5, p=0·05). We did not detect significant differences between cases and controls in terms of lung function, lipid profile, glucose tolerance, glycated haemoglobin A1c, salivary cortisol, sitting height, and head circumference. INTERPRETATION Our results suggest that SAM has long-term adverse effects. Survivors show patterns of so-called thrifty growth, which is associated with future cardiovascular and metabolic disease. The evidence of catch-up growth and largely preserved cardiometabolic and pulmonary functions suggest the potential for near-full rehabilitation. Future follow-up should try to establish the effects of puberty and later dietary or social transitions on these parameters, as well as explore how best to optimise recovery and quality of life for survivors.

Abstract
OBJECTIVE Diarrhoea is a significant contributer to morbidity and is among the leading causes of death of children living in poverty. As such, the incidence, duration and severity of diarrhoeal episodes in the household are often key variables of interest in a variety of community-based studies. However, there currently exists no means of defining diarrhoeal severity that are (A) specifically designed and adapted for community-based studies, (B) associated with poorer child outcomes and (C) agreed on by the majority of researchers. Clinical severity scores do exist and are used in healthcare settings, but these tend to focus on relatively moderate-to-severe dehydrating and dysenteric disease, require trained observation of the child and, given the variability of access and utilisation of healthcare, fail to sufficiently describe the spectrum of disease in the community setting. DESIGN Longitudinal cohort study. SETTING Santa Clara de Nanay, a rural community in the Northern Peruvian Amazon. PARTICIPANTS 442 infants and children 0-72 months of age. MAIN OUTCOME MEASURES Change in weight over 1-month intervals and change in length/height over 9-month intervals. RESULTS Diarrhoeal episodes with symptoms of fever, anorexia, vomiting, greater number of liquid stools per day and greater number of total stools per day were associated with poorer weight gain compared with episodes without these symptoms. An instrument to measure the severity was constructed based on the duration of these symptoms over the course of a diarrhoeal episode. CONCLUSIONS In order to address limitations of existing diarrhoeal severity scores in the context of community-based studies, we propose an instrument comprised of diarrhoea-associated symptoms easily measured by community health workers and based on the association of these symptoms with poorer child growth. This instrument can be used to test the impact of interventions on the burden of diarrhoeal disease.

Abstract
BACKGROUND Stunting is a consequence of long term, cumulative inadequacies of health and nutrition. Health system uses underweight for growth monitoring for its simplicity. Lately there is renewed interest in stunting and especially severe acute malnutrition. Stunting is a relatively neglected indicator. It is therefore imperative to understand the causes of stunting early in infancy and childhood, so that preventive measures can be taken. Hence, the present study was undertaken to study the social determinants of stunting in rural Wardha. METHODS The present cross-sectional study was undertaken in three Primary Health Centres (PHCs) of Wardha district with total population of 88,187. The sample was drawn from three PHC areas by 30-cluster sampling technique. Stunting was defined using WHO Child Growth Standards for 'height-for-age'. 'Height-for-age' values below 2 standard deviations were considered as stunted while below 3 standard deviations were considered 'severe stunting'. RESULT Prevalence of stunting was observed to be 52.3% and severe stunting was 25.1%. The significant determinants of stunting were found to be age, father's education, fathers' occupation, low income, not receiving Vitamin-A supplement during last 6 months and having anaemia. Sex, caste, mother's education and mothers' occupation did not contribute significantly to the stunting. CONCLUSION Low income and related factors such as father's education and his occupation are important determinant of the stunting. Father being the decision maker, his education is of importance. Vitamin-A supplementation and anaemia as surrogate indicators for access to health care also found out to be significant determinants of stunting.

Lee G, Pan W, Peñataro Yori P, Paredes Olortegui M, Tilley D, Gregory M, Oberhelman R, Burga R, Chavez CB, Kosek M. Symptomatic and asymptomatic Campylobacter infections associated with reduced growth in Peruvian children. PLoS Negl Trop Dis 2013; 7:e2036. [PMID: 23383356 PMCID: PMC3561130 DOI: 10.1371/journal.pntd.0002036] [Citation(s) in RCA: 108] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2012] [Accepted: 12/12/2012] [Indexed: 12/14/2022] Open
Abstract
Background Although diarrheal illnesses are recognized as both a cause and effect of undernutrition, evidence for the effect of specific enteropathogens on early childhood growth remains limited. We estimated the effects of undernutrition as a risk factor for campylobacteriosis, as well as associations between symptomatic and asymptomatic Campylobacter infections and growth. Methodology/Principal Findings Using data from a prospective cohort of 442 children aged 0–72 months, the effect of nutritional status on the incidence of Campylobacter infection was estimated using uni- and multivariate Poisson models. Multivariate regression models were developed to evaluate the effect of Campylobacter infection on weight gain and linear growth. Overall, 8.3% of diarrheal episodes were associated with Campylobacter (crude incidence rate = 0.37 episodes/year) and 4.9% of quarterly asymptomatic samples were Campylobacter positive. In univariate models, the incidence of Campylobacter infection was marginally higher in stunted than non-stunted children (IRR 1.270, 95% CI (0.960, 1.681)(p = 0.095). When recent diarrheal burdens were included in the analysis, there was no difference in risk between stunted and unstunted children. Asymptomatic and symptomatic Campylobacter infections were associated with reduced weight gain over a three-month period (65.5 g (95% CI: −128.0, −3.0)(p = 0.040) and 43.9 g (95% CI:−87.6, −1.0)(p = 0.049) less weight gain, respectively). Symptomatic Campylobacter infections were only marginally associated with reduced linear growth over a nine month period (−0.059 cm per episode, 95% CI: −0.118, 0.001)(p = 0.054), however relatively severe episodes were associated with reduced linear growth (−0.169 cm/episode, 95% CI −0.310, −0.028)(p = 0.019). Conclusions/Significance Our findings suggest that Campylobacter is not as benign as commonly assumed, and that there is evidence to support expanding the indications for antibiotic therapy in campylobacteriosis in children. Campylobacter is a common cause of diarrheal disease among children at risk for growth failure in the developing world. We evaluated risk factors for Campylobacter infection as well as the association between symptomatic and asymptomatic Campylobacter infections and child growth over three and nine-month periods. Undernourished (stunted) children were more likely to experience a Campylobacter infection, but adjusting for a recent history of diarrheal disease attenuated this relationship. Both symptomatic and asymptomatic infections were associated with poorer weight gain and symptomatic Campylobacter infections were marginally associated with poorer linear growth on an order similar to what has been reported for other bacterial pathogens and less than what has been reported for some protozoal and parasitic infections. In a subset of severe infections that made up about twenty percent of total illnesses, the associations were poorer growth were of greater magnitude. Campylobacter infections are frequently viewed as benign, but our study suggests that this is not always the case. Rapid diagnostics for Campylobacter jejuni and coli could attenuate acquired linear growth deficits in populations where campylobacteriosis is highly endemic by facilitating improved case management.

Association between infant nutrition and anthropometry, and pre-pubertal body composition in urban South African children. J Dev Orig Health Dis 2012; 3:415-23.

Abstract
Early life nutrition and growth are related to subsequent obesity risk in high-income countries. We investigated the association between nutrition and growth during infancy, and body composition at 10 years of age in 140 children selected from the Bone Health sub-study of the Birth-to-Twenty cohort from Soweto, Johannesburg, South Africa. Infant feeding and dietary data were collected during the first 12 months, and weight and height were measured at 1 and 2 years of age. At 10 years, anthropometry and dual-energy X-ray absorptiometry (DXA)-derived body composition were measured. Regression models were used to determine associations between independent and dependent variables at the 1% level of significance. A one z-score increase in birth weight was associated with a 1051 g increase in lean mass and a 0.22 increase in body mass index (BMI) z-score at the age of 10 years. After adjusting for confounders, stunting at age 1 year was associated with lower fat mass only at 10 years of age while at age 2 years, it was associated with lower lean mass only. Being underweight at one year of age was significantly associated with lower lean mass only. Weight-for-age (WAZ) change in the second year of infancy was a predictor of fat mass and BMI only. Body fatness at 10 years of age was positively associated with infant WAZ change rather than height-for-age change. There were no significant associations between infant dietary patterns, wasting and being underweight at age 2 years and pre-pubertal body composition. Further studies are needed to assess whether these associations continue during adolescence as pubertal development may be an important modifier of these associations.

Abstract
OBJECTIVE To investigate the relationship between maternal depression and child growth in developing countries through a systematic literature review and meta-analysis. METHODS Six databases were searched for studies from developing countries on maternal depression and child growth published up until 2010. Standard meta-analytical methods were followed and pooled odds ratios (ORs) for underweight and stunting in the children of depressed mothers were calculated using random effects models for all studies and for subsets of studies that met strict criteria on study design, exposure to maternal depression and outcome variables. The population attributable risk (PAR) was estimated for selected studies. FINDINGS Seventeen studies including a total of 13,923 mother and child pairs from 11 countries met inclusion criteria. The children of mothers with depression or depressive symptoms were more likely to be underweight (OR: 1.5; 95% confidence interval, CI: 1.2-1.8) or stunted (OR: 1.4; 95% CI: 1.2-1.7). Subanalysis of three longitudinal studies showed a stronger effect: the OR for underweight was 2.2 (95% CI: 1.5-3.2) and for stunting, 2.0 (95% CI: 1.0-3.9). The PAR for selected studies indicated that if the infant population were entirely unexposed to maternal depressive symptoms 23% to 29% fewer children would be underweight or stunted. CONCLUSION Maternal depression was associated with early childhood underweight and stunting. Rigorous prospective studies are needed to identify mechanisms and causes. Early identification, treatment and prevention of maternal depression may help reduce child stunting and underweight in developing countries.

Abstract
AbstractObjectiveThe goal of the present study was to examine the influence of community environment on the nutritional status (weight-for-age and height-for-age) of children (aged 0–59 months) in Bangladesh. In addition, we tested the association between specific characteristics of community environments and child nutritional status.DesignCross-sectional survey.SettingThe data are from the nationally representative 2004 Bangladesh Demographic and Health Survey.SubjectsRespondents were ever-married women (aged 15–49 years) and their children (n 5731), residing in 361 communities. Child nutritional outcomes are physical measurements of weight-for-age and height-for-age in sd units. We considered the following attributes of community environments potentially related to child nutrition: (i) community water and sanitation infrastructure; (ii) availability of community health and education services; (iii) community employment and social participation; and (iv) education level of the community.ResultsMultilevel regression analysis showed that the spatial distribution of maternal and child covariates did not entirely explain the between-community variation in child nutritional status. The education level of the community emerged as the strongest community-level predictor of child height-for-age (highest v. lowest tertile, β = 0·18 (se 0·07)) and weight-for-age (highest v. lowest tertile, β = 0·21 (se 0·06)). In the height-for-age model, community employment and social participation also emerged as being statistically significant (highest v. lowest tertile, β = 0·13 (se = 0·06)).ConclusionsThe community environment influences child nutrition in Bangladesh, and maternal- and child-level covariates may fail to capture the entire influence of communities. Interventions to reduce child undernutrition in developing countries should take into consideration the wider community context.

Abstract
OBJECTIVE To estimate the prevalence of global developmental delay among children under 3 years of age and study the determinant factors. METHODS Cross sectional descriptive study was conducted in field practice areas of the Department of Community Medicine, JN Medical College, Aligarh, India. A total of 468 (243 boys and 225 girls) children aged 0-3 years were included. Developmental screening was performed for each child. A multitude of biological and environmental factors were analysed. RESULTS As many as 7.1% of the children screened positive for global developmental delay. Maximum delay was observed in the 0-12 months age group (7.0%). Undernutrition and prematurity were the two most prevalent etiological diagnoses (21% each). Stunting and maternal illiteracy were the microenvironmental predictors on stepwise binary logistic regression while prematurity and a history of seizures emerged significant biological predictors. CONCLUSIONS Developmental delay can be predicted by specific biological and environmental factors which would help in initiating appropriate interventions.

Abstract
BACKGROUND Previous growth studies of Peruvian children have featured high stunting rates and limited information about body composition. OBJECTIVE We aimed to characterize anthropometric measures of Peruvian infants 0 to 12 months of age in relation to the international growth references and biological, environmental, and socioeconomic factors. METHODS Infants (n = 232) were followed longitudinally from birth through 12 months of age from a prenatal zinc supplementation trial conducted in Lima, Peru, between 1995 and 1997. Anthropometric measures of growth and body composition were obtained at enrollment from mothers and monthly through 1 year of age from infants. Weekly morbidity and dietary intake surveillance was carried out during the second half of infancy. RESULTS The prevalence rates of stunting, underweight, and wasting did not exceed 4% based on the World Health Organization growth references. Infants of mothers from high-altitude regions had larger chest circumference (p = .006) and greater length (p = .06) by 12 months. Significant predictors of growth and body composition throughout infancy were age, sex, anthropometric measurements at birth, breastfeeding, maternal anthropometric measurements, primiparity, prevalence of diarrhea among children, and the altitude of the region of maternal origin. No associations were found for maternal education, asset ownership, or sanitation and hygiene factors. CONCLUSIONS Peruvian infants in this urban setting had lower rates of stunting than expected. Proximal and familial conditions influenced growth throughout infancy.

Abstract
OBJECTIVE To examine the association between household socio-economic status (SES) at birth and poor infant growth such as small for gestational age (SGA) and stunting across two different socio-cultural settings: South Africa and the Philippines. DESIGN Data were from two longitudinal birth cohorts, the Birth to Twenty (Bt20) study in South Africa and the Cebu Longitudinal Health and Nutrition Survey (CLHNS) in the Philippines. SUBJECTS Bt20 infants (n 2293 total; reduced to 758 (SGA), 450 (stunting 1 year) and 401 (stunting 2 years)) and CLHNS infants (n 2513 total; reduced to 2161 (SGA), 1820 (stunting 1 year) and 1710 (stunting 2 years)). RESULTS CLHNS infants were significantly more likely to be born SGA (20.9 v. 11.7 %) and be stunted at 1 year (32.6 v. 8.7 %) and 2 years (48.9 v. 21.1 %) compared with Bt20 infants. Logistic regression analyses showed that SES (index) was a significant predictor of stunting at 1 and 2 years of age in the CLHNS cohort. SES (index or individual variables) was not a significant predictor of SGA in either cohort, or of stunting in the Bt20 cohort. Maternal education, ownership of a television and toilet facilities were all independent predictors of stunting in the CLHNS cohort. CONCLUSIONS The social and economic milieu within the Philippines appears to place CLHNS infants at greater risk of being born SGA and being stunted compared with Bt20 infants. The present research highlights the importance of investigating the individual SES variables that predict infantile growth faltering, to identify the key areas for context-specific policy development and intervention.

Abstract
OBJECTIVES To explore the developmental origins of cardiorespiratory fitness. METHODS We examined the associations of birth size and duration of breast feeding with cardiorespiratory fitness assessed at the 9 year follow-up examination in 3612 participants of the Avon Longitudinal Study of Parents and Children (ALSPAC). We used physical work capacity at a heart rate of 170 beats per minute (PWC(170)) as our assessment of cardiorespiratory fitness. This was estimated using standard regression methods from parameters measured using an electronically braked cycle ergometer. RESULTS Birth weight, length and ponderal index were all positively associated with cardiorespiratory fitness in both sexes, with no strong evidence of a difference in effect between girls and boys. Work capacity increased by 1.12 W (95% CI: 0.83, 1.40) on average per 1 standard deviation (SD) greater birth weight. This association was not affected by adjustment for socioeconomic position and maternal smoking during pregnancy; there was some attenuation with adjustment for both maternal and paternal height and body mass index and more marked attenuation with adjustment for the child's height and body mass index. In the fully adjusted model work capacity increased by 0.51 W (95% CI: 0.21, 0.81) per SD birth weight. Whether an individual had been breastfed and duration of breastfeeding were not associated with cardiorespiratory fitness in any models. CONCLUSION Our results provide some support for a role of intrauterine factors in determining cardiorespiratory fitness in childhood.

Abstract
Linear growth retardation and anemia are the most prevalent nutritional problems in the world; effective interventions are urgently needed. We evaluated Ecuador's National Food Nutrition Program (PANN 2000) that included a micronutrient-fortified complementary food (FCF), Mi Papilla, in poor periurban and rural communities of Ecuador. The program is preventive and targeted to all infants and young children living in poor communities and receiving government health services. We compared dietary intake, micronutrient status, and growth over 11 mo in a cohort of children from the catchment areas of the PANN 2000 with same-age control children in nearby communities eligible to enter the program 1 y later. PANN 2000 children enrolled in the program when they were age 9-14 mo and were age 20-25 mo at the final survey. They consumed significantly more energy, protein, fat, iron, zinc, vitamin A, and calcium than control children because of their FCF consumption. Anemia, 76% in both groups at baseline, fell to 27% in PANN 2000 children but only to 44% in control children (P < 0.001). The odds of being anemic were 58% lower for PANN 2000 children (P = 0.003). The effects on linear growth and weight were limited to children who were older when the program began (12-14 mo) and were significant for weight (interaction with age, 0.38 kg; P = 0.029) and positive but not significant for length (0.66 cm; P = 0.08). An FCF, including ferrous sulfate, delivered through public health services, is highly effective in improving weight and hemoglobin and reducing anemia.

Abstract
We performed a cross-sectional, community-based survey, supplemented by interviews with community leaders in Chiapas, Mexico, to examine the prevalence and predictors of child malnutrition in regions affected by the Zapatista conflict. The prevalence rates of stunting, wasting, and underweight were 54.1%, 2.9%, and 20.3%, respectively, in 2666 children aged younger than 5 years. Stunting was associated with indigenous ethnicity, poverty, region of residence, and intracommunity division. The results indicate that malnutrition is a serious public health problem in the studied regions.

Abstract
Quality of life scores of health conditions are needed for measuring quality adjusted life years (QALY), the most common outcome measure in cost-utility analysis. To measure QALY scores we used EQ-5D and a visual analogue scales (VIS). EQ-5D is a standardised instrument for measuring quality of life using five dimensions applicable to a wide range of health conditions. VAS had the endpoints "full health" and "death". We assessed the scores for chronic energy deficiency (CED) characterised by low body mass index (BMI<18.5), a condition highly prevalent among rural Bangladeshi women. EuroQol (EQ)-5D and VAS were used to measure when the condition was worst and VAS measured the current health status. We interviewed 285 pregnant and postpartum women, with 236 (83%) having complete information. Mean scores for CED when perceived to be most severe were 0.30 (EQ-5D, interquartile range -0.02 to 0.52) and 0.27 (visual analogue scale, interquartile range 0.12-0.39) in scales with scores ranging from -0.54 to 1.00 and from 0 to 1.00, respectively. The mean score for current health status derived from the visual analogue scale was 0.49 (95% CI for mean 0.45-0.52) in a scale with scores ranging from 0 to 1.00. Rural Bangladeshi women attached very low quality of life scores to CED. The scores are comparable to scores attached to severe debilitating conditions like cancer in western countries. If considered in the global perspective, prevention of chronic energy deficiency among women in developing countries should be given high priority.

Abstract
OBJECTIVE The purpose of this paper is to examine the relationship between childhood undernutrition and poverty in urban and rural areas. DESIGN Anthropometric and socio-economic data from Multiple Indicator Cluster Surveys in Angola-Secured Territory (Angola ST), Central African Republic and Senegal were used in this analysis. The population considered in this study is children 0-59 months, whose records include complete anthropometric data on height, weight, age, gender, socio-economic level and urban or rural area of residence. In addition to simple urban/rural comparisons, the population was stratified using a wealth index based on living conditions and asset ownership to compare the prevalence, mean Z-score and odds ratios for stunting and wasting. RESULTS In all cases, when using a simple urban/rural comparison, the prevalence of stunting was significantly higher in rural areas. However, when the urban and rural populations were stratified using a measure of wealth, the differences in prevalence of stunting and underweight in urban and rural areas of Angola ST, Central African Republic and Senegal disappeared. Poor children in these urban areas were just as likely to be stunted or underweight as poor children living in rural areas. The odds ratio of stunting in the poorest compared with the richest quintile was 3.4, 3.2 and 1.5 in Angola ST, Senegal and Central African Republic, respectively. CONCLUSIONS This paper demonstrates that simple urban/rural comparisons mask wide disparities in subgroups according to wealth. There is a strong relationship between poverty and chronic undernutrition in both urban and rural areas; this relationship does not change simply by living in an urban environment. However, urban and rural living conditions and lifestyles differ, and it is important to consider these differences when designing programmes and policies to address undernutrition.

Abstract
Whether the determinants of linear growth can have independent effects beyond the critical infancy period has been questioned. This research uses uniquely suited data from >2000 youths from the Cebu Longitudinal Health and Nutrition Study in the Philippines to examine the association between diet and height in the postinfancy period. Anthropometric, diet, and other data were collected bimonthly from 0 to 2 y, and at the mean ages of 8, 11.5, 15.5, and 18.5 y. Generalized Estimating Equations were used to quantify the mean effects of diet diversity and energy intake on height across increments demarcated by the postinfancy data (2-8.5, 8.5-11.5, 11.5-15.5, and 15.5-18.5 y). We examined whether the effects differed by socioeconomic status (SES) and age. Effects with P < 0.05 were considered significant. Each additional unit of diet variety (range 0-8 U) was associated with a significant 0.33-cm increase in height in boys. Each additional 100 kcal (4186 kJ) was associated with significant increases in height of 0.05 cm in boys, and 0.02 cm in girls. Significant interactions (P < 0.15) with SES showed that each 100 kcal increase in energy intake was associated with a 0.08-cm increase in height at low SES with no difference at high SES. In both boys and girls, the effects of energy intake decreased with age, as shown by a significant age interaction (P < 0.15). The methods used incorporate the longitudinal nature of the data to offer a unique examination of the association between diet and height in the postinfancy period.

Abstract
In Latin America and the Caribbean (LAC) about one in six children under 5 years of age--or about 9 million children--suffer from longer-run undernourishment reflected in stunting. This paper introduces, places in perspective and presents a common micro analytical framework for the seven papers in this symposium that investigate the household and community determinants of child malnourishment in eight countries in LAC. These papers are the outcomes of a research project supported by the Inter-American Development Bank (IDB) Research Department Latin American and Caribbean Research Network Project on "Child Health, Poverty and the Role of Social Policies" in 2003-2004.

Abstract
BACKGROUND Despite our knowledge of the negative consequences of stunting during early childhood and the important role that maternal nutritional status plays in the development of intrauterine growth retardation, we do not know the extent to which maternal nutritional status influences the growth in length of the fetus or whether a sensitive period for fetal linear growth exists during gestation. OBJECTIVE Our objective was to explore the relation between maternal weight gain during different stages of pregnancy and linear growth of the fetus. DESIGN Ultrasound examinations were conducted at 15-24 (x: 17.5) and 28-32 (x: 29.9) wk of gestation in 200 women from 4 rural Guatemalan villages. The associations between maternal weight gain from approximately 10 to 20 and 20 to 30 wk of pregnancy (from the first to the second and from the second to the third trimester, respectively) and fetal linear growth were tested with the use of ordinary least-squares regression. RESULTS Maternal weight gain from the first to the second trimester was associated with fetal femur and tibia lengths measured at both means of 17 and 30 wk (P < 0.05) and infant length at birth (P < 0.001). Weight gain from the second to the third trimester of pregnancy did not predict fetal linear growth or infant length at birth. CONCLUSIONS Maternal weight change from the first to the second trimester of pregnancy is strongly associated with fetal growth. Mid-gestation may be a sensitive period for fetal linear growth.

Abstract
A cross-sectional household survey of height among children under five years of age (n = 2,632) was conducted in the city of Porto Alegre, Rio Grande do Sul State, Brazil. Multi-level linear regression was applied to investigate the effect of socioeconomic and demographic factors, physical and social environment, and health conditions on children s height, measured by the height-for-age z-scores of the National Center for Health Statistics standards. Area of residence (census tract) was classified as good versus poor in terms of housing and sanitation standards. On average, children s height was -0.18 z-score. Average height increased with maternal and paternal schooling, parents work skills, per capita family income, improved housing, maternal age, birth intervals, and birth weight. Height decreased with hospitalization in the first two years of life, number of under-five children in the household, and preterm birth. In the poor residential areas, the effect of maternal schooling was twice as great as in the better-off areas. The effect of parental work skills was only evident in the more deprived areas. Area of residence modified the effects of socioeconomic conditions on children s growth. Housing and sanitation programs are potentially beneficial to offset the negative effect of social disadvantage on children's growth.

Abstract
To alleviate poverty in developing countries, economies must grow. Without the necessary investments in human capital, national economic growth may not lead to poverty alleviation and socioeconomic development, nor be sustainable. Economic growth that leads to poverty alleviation is fueled by the creative and physical capacities of people. The impact of micronutrient malnutrition is established early in life, leading to growth stunting, lower cognitive abilities, lethargy and poor attention, and greater severity and rates of infection. These effects limit educational progress, physical work capacity and life expectancy, thereby reducing individual lifetime productivity and the aggregate ability of the population to enhance its well-being and participate in national and global markets. The diets of the poor are largely cereal-based, monotonous and lacking in diversity and micronutrients. Animal source foods (ASF) have been an important factor in human evolution, a component of what was an historically diverse diet and an important source of micronutrients. Poverty and micronutrient malnutrition positively influence each other. This poverty micronutrient malnutrition (PMM) trap requires outside inputs to change the state of development in developing countries. Nutrition interventions have been excellent investments in development. More productive interaction between agricultural scientists and nutritionists, supported by a strong federal agenda for development, is needed to break the PMM trap. In the end, food is the means by which nutrients are delivered. Food-based approaches will require long-term commitments, but are more likely to be sustainable because they are part of a development process that leads to long-term economic growth.

Abstract
In developing countries, heavy workloads of women adversely affect their nutritional status and that of their children. Little is known, however, about the effect of children's heavy workloads on their own well-being. In Nepal, girls are expected to help their mothers in time-consuming and energy-demanding tasks from an early age. The aim of this study was to compare work patterns and anthropometric status of boys and girls age 6-17 years in western rural Nepal. It was hypothesized that girls would work longer and harder than boys and would have poorer growth status. It was also anticipated that children's work patterns might differ between highland and lowland areas. Two study sites were therefore chosen: one in the hills and the other in the lowland terai. A time allocation study was conducted for 237 children. They were observed continuously from 7:00 AM to 7:00 PM to determine the time spent in light, moderate, and heavy activities. Body weights and heights were also measured. On average, girls worked twice as long as boys (5.8 vs. 2.8 h/day, P < 0.001) and undertook more heavy work (1.5 vs. 0.7 h/day, (P < 0.001), but they did not have poorer anthropometric status. Children in the hills worked longer hours and did heavier work than those in the terai and were more stunted in growth.

Abstract
The "fetal origins" hypothesis postulates that conditions, most likely nutritional, "program" the fetus for the development of chronic diseases in adulthood. Associations between the newborn's size at birth and various determinants or consequences of chronic diseases have been identified in many, but not all, of the available studies. It remains to be established whether these associations are causal. Remarkably little information is available on the specific role of maternal nutritional status. The role of birth weight remains difficult to interpret except as a proxy for events in intrauterine life. Unfortunately, birth weight does not make an important contribution to the population attributable risk of cardiovascular disease; lifestyle factors during adulthood make much greater contributions. Data from experimental species suggest possible mechanisms for the origin of chronic disease early in life. It is too soon to use this research as a basis for new interventions directed at pregnant women for the purpose of reducing chronic disease in their offspring.

Abstract
BACKGROUND The prevalence of stunting in preschool children in Zambia is high; stunting has detrimental effects on concurrent psychomotor development and later working capacity. OBJECTIVE Our objective was to investigate biological variables that may contribute to linear growth retardation in preschool children in Samfya District, Zambia. DESIGN Children aged 6-9 mo (n = 108) and 14-20 mo (n = 102) attending mother-and-child health clinics were included. With a mixed-longitudinal design, they were followed up 9 and 21 mo later. Height and weight of children and their mothers were measured. Biochemical measures (eg, serum zinc, retinol, thyrotropin, iron, and acute phase protein concentrations), malaria parasitemia, and intestinal parasitosis were assessed. RESULTS Height-for-age z scores (HAZ) were low, indicating a high prevalence of stunting (36-79%). Ninety percent of the children were anemic, 53-71% had elevated acute phase proteins, and 80% had malaria parasitemia. Regression analyses showed that maternal height predicted the children's height at 6-9 mo (regression coefficient = 0.05; 95% CI: 0.02, 0.08). The children's height at an early age (6-9 and 14-20 mo) showed a strong relation with their height at later ages (22-30 and 34-41 mo). Serum micronutrient status did not show a significant relation with later HAZ. CONCLUSION Unlike other studies, we did not identify specific biological factors, such as health and micronutrient status, which contribute to the retardation of linear growth. The normal zinc and iodine statuses of the children suggest that at least these factors are not causal.

Abstract
Low birth weight has many adverse consequences, some of which might be ameliorated if there is good postnatal compensatory, or catch-up, growth. We monitored growth, morbidity and feeding patterns in a cohort of 133 full-term, low birth weight infants from poor families in Pernambuco, Brazil, and investigated the relative contributions of a number of socioeconomic, maternal and infant variables to postnatal growth. Growth was measured at 4, 8, 17, 26 and 52 wk of age. Differential growth patterns were most marked during the first 8 wk of life, and the gains in z-score during this interval were strongly associated with attained z-scores at 12 months (r = 0.62 for weight and 0.64 for length). In a multivariate model, socioeconomic variables explained 21.4% of the variation in maximum gain in weight-for-age z-score achieved during the 12-month period, maternal weight explained a further 4.4%, infant birth length 4.7% and neonatal illness 5.4%. For maximum gain in length-for-age z-score, socioeconomic variables accounted for 24.4% of the variance, maternal height 4.9%, maternal smoking 3.3% and neonatal illness 3.1%. We surmise that the early differential growth patterns are set in utero and are indirectly affected prenatally by socioeconomic status.
