“…Association of independent variables with tooth brushing is assessed through logistic regression analysis and presented by crude and adjusted OR (95 % CI). Decomposition of the gap in tooth brushing between the first and fifth quintiles of SES was evaluated using the counterfactual decomposition technique which is widely used to study mean outcome differences between groups [ 18 , 24 , 25 ].…”

BackgroundThe present study set to describe the socioeconomic inequality associated with oral hygiene behavior among Iranian pediatric population.MethodsA representative sample of 13486 school students aged 6–18 years was selected through multistage random cluster sampling method from urban and rural areas of 30 provinces in Iran. Principle Component Analyses (PCA) correlated variables summarized as socioeconomic status (SES). Association of independent variables with tooth brushing was assessed through logistic regression analysis. Decomposition of the gap in tooth brushing between the first and fifth SES quintiles was assessed using the counterfactual decomposition technique. To assess the relation between tooth brushing and each socioeconomic category, Concentration Index (C) and the slope index of inequality (SII) were used, representing the linear regression coefficient.ResultsThe participation rate was 90.6 % (50.7 % boys and 75.6 % urban inhabitants). The mean age of participants was 12.47 ± 3.36 years. The frequency of tooth brushing increased across SES quintiles, prevalence of tooth brushing between the first and fifth quintile, under 20 % difference, increased from 58.22 (95 % CI: 56.24,60.20) to 78.61 (95 % CI: 77.00,80.24). Only 3 % of the difference is explained by the factors considered in the study, and 17 % remained unknown. Residence area, family size, and smoking status made a significant contribution to the gap between the first and last SE groups. Residence area [ −2.01 (95 % CI: −3.46, −0.55)] was along the maximum levels of gaps between SE categories.ConclusionsThe findings revealed a socio-economic inequality in oral health behavior in Iranian children and adolescents. Also, factors influencing oral health are addressed to develop and implement complementary public health actions.

“…15 The results can be obtained from wchung@yuhs.ac 16 In order to decompose the main factors underlying the decline in the probability of stating "must have a son" (intensity of son preference), we used the econometric method extended from original models within regression analyses suggested by Oaxaca and Blinder (Blinder 1973;Oaxaca 1973) to models of discrete choice with a binary dependent variable (Borooah and Iyer 2005;Gomulka and Stern 1990;Nielsen 1998). Yun (2004) and Powers (2006) recently developed a method to overcome a "path dependence" problem-namely that, in nonlinear models, the independent contribution of one variable to the difference depends on the values of the other variables and on the order in which these variables are entered in the decomposition.…”

For years, sex ratios at birth kept rising in South Korea despite rapid development. We show that this was not an anomaly: underlying son preference fell with development, but the effect of son preference on sex ratios at birth rose until the mid-1990s as a result of improved sex-selection technology. Now South Korea leads Asia with a declining sex ratio at birth. We explore how son preference was affected by development and by public policy. Decomposition analysis indicates that development reduced son preference primarily through triggering normative changes across society-rather than just in individuals whose socioeconomic circumstances had changed. The cultural underpinnings of son preference in preindustrial Korea were unraveled by industrialization and urbanization even as public policies sought to uphold the patriarchal family system. Our results suggest that child sex ratios in China and India may decline before those countries reach South Korean levels of development, since the governments of both countries vigorously promote normative change to reduce son preference.

“…This approach has been the most frequently used in recent decades to identify and quantify the underlying causes of differences between races or individuals of different genders observed on the labour market, in education and in many other areas. Still more recently, it has been used to explain the difference in the level of poverty and inequality (Booroah and Iyer, 2005;Biewen and Jenkins, 2005;Bhaumik et al, 2006;Adoho and Boccanfuso, 2007).…”

Despite notable progress, under-5 mortality remains a major issue in developing countries.Malnutrition continues to be a serious problem, and its reduction remains the primary target of health policies developed in many countries and organizations. In Guinea, contrary to other African countries, the rate of stunting for children under 5 years of age has increased between 1999 and 2005. To be able to recommend policies to improve the nutritional status of Guinean children, we used an approach to decompose the nutritional status gap of Guinean children that was observed into the effects of changes in the means of the determinants of nutritional status and changes in the effects of the determinants of nutritional status.The results indicate that, regardless of the health indicator considered, the aggregate effect of the coefficients is substantially stronger than that of the characteristics. With this study, we further explain the health status of children.Malgré les progrès notables de la médecine, la mortalité infanto-juvénile reste un enjeu majeur dans les pays en développement. L'une des principales causes de cette mortalité, la malnutrition, reste un fléau important et sa réduction demeure la cible principale de nombreuses politiques en matière de santé, développées dans plusieurs pays et organisations internationales. En Guinée, contrairement à certains pays africains, les taux de retard de croissance des enfants de moins de 5 ans ainsi que celui de l'insuffisance pondérale ont augmenté entre 1999 et 2005. Afin de recommander des politiques visant à contribuer à l'amélioration de l'état nutritionnel des enfants guinéens, nous décomposons l'écart de l'état nutritionnel des enfants guinéens observé entre 1999 et 2005 en l'effet détaillé de ses caractéristiques et celui des coefficients des caractéristiques. Les résultats montrent que quelque soit l'indicateur de santé considéré, l'effet agrégé des coefficients l'emporte significativement sur celui des caractéristiques.
