Does living in an urban environment confer advantages for childhood nutritional status? Analysis of disparities in nutritional status by wealth and residence in Angola, Central African Republic and Senegal

AbstractObjectiveThe purpose of this paper is to examine the relationship between childhood undernutrition and poverty in urban and rural areas.DesignAnthropometric 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.ResultsIn 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.ConclusionsThis 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

Dietary diversity score is a useful indicator of micronutrient intake in non-breastfeeding Filippino children

Micronutrient malnutrition remains a problem of public health concern in most developing countries, partly due to monotonous, cereal-based diets that lack diversity. The study objective was to assess whether dietary diversity score (DDS) based on a simple count of food groups consumed and DDS using a 10-g minimum intake for each food group (DDS 10g) are good indicators of adequate micronutrient intake in 24–71-mo-old non-breast-feeding Filipino children. Pearson’s correlation and linear regression were used to assess the utility of DDS and DDS 10g as indicators of micronutrient intake. Sensitivity and specificity analysis were used to determine the most appropriate cut-off point for using DDS to categorize children with high probability of adequate micronutrient intake. The average diet of the sample population consisted of 4–5 food groups. The mean probability of adequate nutrient intake (MPA) of 11 micronutrients was 33%. The Pearson’s correlation coefficient between MPA and DDS was 0.36 (P , 0.001) and for DDS 10g it increased to 0.44 (P , 0.001). Intake of individual micronutrients was correlated to DDS for most nutrients. When maximizing sensitivity and specificity, the best cut-off points for achieving 50 and 75% probability of adequate micronutrient intake were 5 and 6 food groups, respectively. DDS and DDS 10g were both significant predictors of adequate micronutrient intake. This study demonstrates the utility of indicators of dietary diversity to predict adequate intake of micronutrients in the diets of young non-breast-feeding childre

Pratiques de la communication et Big Data

Le phénomène des Big Data s’est rapidement imposé comme un enjeu majeur au niveau mondial pour les organisations qui les collectent et les exploitent, mais il l’est tout autant pour les individus dont les traces numériques sont suivies, répertoriées, analysées et croisées que pour les institutions qui ont pour objectif de réguler les systèmes d’information et de protection de la vie privée. Le numéro 54 de la revue Communication & Organisation veut questionner les enjeux liés aux Big Data dans une perspective informationnelle et communicationnelle tout en tenant compte des ramifications managériales que sous-tend l’usage stratégique des données massives. Cinq défis auxquels doivent faire face les professionnels de la communication en organisation sont évoqués dans ce numéro : la montée en compétences et la professionnalisation ; la pertinence stratégique ; la qualification et le traitement ; la confiance et la défiance ; et enfin, différents modèles de présence numérique. Confronté aux données massives, comment le professionnel de la communication peut-il composer avec le paradoxe de la volatilité versus de la permanence de la présence numérique ? C’est ce que ce numéro questionne à travers les différents thèmes évoqués
