Child feeding practices are associated with child nutritional status in Latin America: innovative uses of the demographic and health surveys

Data from the Demographic and Health Surveys (DHS) for 5 Latin American countries (7 data sets) were used to explore the feasibility of creating a composite feeding index and to examine the association between feeding practices and child height-for-age Z-scores (HAZ). The variables used for the index were as follows: current breast-feeding, use of complementary foods and liquids in the past 24 h, frequency of use over the past week and feeding frequency. The index was made age specific for 6- to 9-, 9- to 12- and 12- to 36-mo-old age groups, and age-specific feeding terciles were created. Bivariate analyses showed that feeding practices were strongly and significantly associated with child HAZ in all 7 data sets, especially after 12 mo of age. Differences in HAZ between child feeding terciles remained significant after controlling for potentially confounding influences, for all countries except Bolivia. Multiple regression analyses also revealed that better feeding practices were more important for children of lower, compared with higher socioeconomic status (in Colombia 1995 and Nicaragua 1998); among children of Ladino (Spanish speaking) compared with indigenous origin (in Guatemala 1995); and among children whose mothers had primary schooling compared with mothers with no schooling, or mothers with higher than primary school level (Peru 1996). The data available in DHS data sets can thus be used effectively to create a composite child feeding index and to identify vulnerable groups that could be targeted by nutrition education and behavior change interventions.     

广东省6～18月龄婴幼儿喂养指数分布及与体格发育的相关性研究

目的分析广东地区6—18月龄婴幼儿喂养指数（ICFI）及与体格发育指标之间的相关性,以探讨ICFI应用于定量评估和比较婴幼儿喂养习惯的有效性。方法整群抽取广东省广州市荔湾区（城市）、佛山市南海区（城镇）、江门市新会区（农村）所有已建立健康档案的6—18月龄婴幼儿,问卷凋查喂养现况及测查体格发育。以中国疾病预防控制中心营养与食品安全所提出的ICFI评分体系为依据,计算评价ICFI。使用WHO推荐的Anthro软件计算婴幼儿的年龄别身长z评分（HAZ）、年龄别体重z分（wAz）、身长别体重z分（WHZ）。分析ICFI与各类z评分的相关性。结果共调查6～18月龄婴幼儿1771人,其中男997人,女774人。全省ICFI为（7．05±2．47）,高于全国平均值（5．9±2．6）,其中城市（474人）、城镇（658人）ICFI分别为（7．29±2．25）和（7．39±2．53）,明显高于农村（639人）ICFI（6．52±2．49）（P〈0．05）。6—8月龄（606人）、9～11月龄（317人）、12—18月龄（848人）ICFl分别为（6．59±2．47）、（6．87±2．45）、（7．44±2．42）,ICFI随月龄增加而增加（P〈0．01）。ICFI总合格率49．2％（872／1771）,其中城市、城镇和农村分别为53．0％（251／474）、56．7％（373／658）和38．8％（248／639）,城市、城镇合格率高于农村（P〈0．01）,6—8、9～11、12～18月龄合格率分别为37．6％、46．7％和58．5％,随月龄增加,合格率明显提高（P〈0．01）。城市ICFI与HAZ、WHZ相关（r=0．108、0．117,均P〈0．05）,城镇ICFI与WHZ相关（r=0．104,P〈0．01）。12～18月龄组ICFI与WAZ和HAZ相关（,=0．110、0．136,均P〈0．01）。结论广东省6～18月龄婴幼儿ICFI高于全国平均值。ICFI可在一定程度上反映出婴幼儿群体的生长发育状况,并可用于婴幼儿喂养方法的综合评判,但其应用效度有待改善。     

A young child feeding index is not associated with either height-for-age or height velocity in rural Senegalese children

Ruel and Menon recently published a young child feeding index based on characteristics taken from 24-h and 7-d recalls. A strong positive association was found in 7 Latin American Demographic and Health Surveys for 12- to 36-mo-old children (1). The aim of this study was to test for associations of this index with height-for-age and linear growth in African children. Children (n = 500), aged 12-42 mo, living in a rural area of Senegal were visited in their homes in April-May, and 24-h and 7-d food recalls were conducted with their mothers. Height was measured, and measurements taken 7 mo earlier were used to compute linear growth rates. General linear models were used to adjust for potential confounders (child age and sex, maternal height, BMI, and socioeconomic status). The feeding index was not associated with either height-for-age (adjusted means: -1.01, -1.06, and -1.20 Z-scores for the 1st, 2nd, and 3rd tercile, respectively) or with linear growth (6.2, 6.0, and 6.3 cm/7 mo for the 3 terciles, respectively). Continuing breast-feeding was negatively associated with height-for-age (P < 0.05) and positively associated with linear growth (P < 0.01). Frequent consumption of fruit was positively associated with both (P = 0.059 and P = 0.027, respectively, in adjusted models), whereas food consumption from an animal source was not. In conclusion, the composite feeding index was independent of height and linear growth in these rural African children, due in part to reverse causality between breast-feeding duration and stunting.     

A summary index of infant and child feeding practices is associated with child growth in urban Shanghai

ABSTRACT: BACKGROUND: Recently, an infant and child feeding index (ICFI) constructed on brief recalls of breastfeeding, feeding frequency and food diversification was assumed to provide long-term prediction about child feeding practices. The aim of this study was to investigate the association between the cross-sectional ICFI (CS-ICFI) or longitudinal ICFI (L-ICFI) and child anthropometric indices in downtown Shanghai, China. METHODS: The prospective cohort study included 180 infants aged 5-7 mo with their main caregivers who were visited 3 times every 6 months over 12 months. A CS-ICFI was constructed for each visit by using data on feeding practices based on 24-h and 7-d recalls. An L-ICFI was constructed with use of the 3 CS-ICFIs. The associations between ICFI and length-for-age z score (LAZ), weight-for-age z score (WAZ), and weight-for-length z score (WLZ) were examined. The stability of the CS-ICFI was assessed by using repeatability coefficient (RC). RESULTS: The L-ICFI was positively associated with LAZ and WAZ at Visit 3 (beta=0.151, P=0.040 and beta=0.173, P=0.024, respectively). Moreover, the CS-ICFI at Visit 1 was positively associated with LAZ, WAZ and WLZ (beta=0.160, P=0.029; beta=0.191, P=0.009; beta=0.176, P=0.020) at Visit 3, and the CS-ICFI at Visit 3 was also positively associated with LAZ (beta=0.176, P=0.016). Stability of the CS-ICFI was shown by the value of 0.14 (95% CI: 0.07, 0.31) of the RC, which differed significantly from 0 (P<0.05). CONCLUSIONS: The ICFI constructed on brief recalls based on cross-sectional studies can be used to evaluate the effects of child feeding practice on child growth.     

The role of child temperament in parental child feeding practices and attitudes using a sibling design

Although previous research indicates that parental child feeding practices are one component of a bidirectional relationship between children and parents, little is known about how child temperament operates in this relationship. The purpose of this study was to investigate relationships between child temperament and parental feeding practices and attitudes using a sibling design. By collecting data regarding pairs of siblings, we were able to investigate sibling differences and differential parental treatment. We examined mothers’ and fathers’ perceptions of their two children's temperaments as well as reports of the feeding practices and attitudes they use with each child. Fifty-five mothers and fathers completed questionnaires including the Carey Temperament Scales and the Child Feeding Questionnaire (CFQ). Results from correlation analyses showed that 6 of the 9 father reports of temperament between two siblings were positively related, whereas 1 of the 9 mother reports were positively related. Mothers’ and fathers’ perceptions of temperament were positively correlated for a single child. Some patterns were found between parental reports of sibling temperament and child feeding practices and attitudes, suggesting that temperament plays a role in how parents feed their children.     

The use of inappropriate feeding practices by rural parents and their effect on preschoolers' fruit and vegetable preferences and intake

ObjectiveTo describe the frequency of inappropriate feeding practices used by parents of preschoolers and the impact on a child’s preference for and intake of fruits and vegetables (FV).DesignCross-sectional analysis of baseline data from a telephone interview.SettingA community-based program in rural southeastern Missouri.Participants1555 rural parents participating in the High 5 for Kids project. The mean age of parents was 28.9 years, the mean age for children was 38.0 months, and 52.1% of children were male.Variables MeasuredDemographic characteristics; intake and preferences for FV; inappropriate child feeding practices.AnalysisInappropriate feeding practices, preferences for and intake of FV were examined using Kruskal-Wallis tests and Spearman’s correlations. Logistic regression was used to assess the relationships between FV intake and preference and inappropriate feeding practices.ResultsAn increasing number of inappropriate feeding practices negatively impacted FV preference of children but positively impacted FV intake.Conclusions and ImplicationsThis study documents the public health need to develop programs that guide and advise rural parents on information about how children develop patterns of intake, and how to foster children’s preferences and acceptance of healthful food.
