Repeated measure analysis of variance splits the total explained variability of all length measurements considered in the analysis into two parts (between- and within-child) to http://en.wikipedia.org/wiki/VAV2 reflect the association between attained length and each of the independent variables. Between-child variability refers to differences in levels (average attained length) and within-child variability to differences in shapes of individual growth functions. Proportions of between- and within-child variability explained by a specific variable were calculated considering the corresponding total type III sums of squares as denominators. To assess significance of the independent variables, F-tests for the within-child univariate analysis were corrected based upon http://www.selleckchem.com/screening/tyrosine-kinase-inhibitor-library.html the estimates of sphericity by Greenhouse and Geisser (1959) whenever there was a violation of the assumption of equality of differences between pairs of measurements (sphericity hypothesis). It should be noted that assessment of proportions of variability was the primary objective of this analysis; therefore, investigation of magnitudes and directions of the various effect estimates was considered as beyond its scope. Analyses were carried out using the software SAS (SAS Institute Inc., Cary, NC, USA, version 9). Statistical significance was assessed at the 5% level for all analyses. To examine the influence of parental characteristics on attained child length, mother's age and education were re-coded as categorical variables and analytical groups were collapsed when specific cells had fewer than 15 observations (country-specific categories for both variables are presented in Table?1). Parity was coded in two categories (mothers with fewer than three children vs. three or more). Household income was estimated in national currencies and categorized by country-specific quartiles. Duration of breastfeeding was calculated in months as the difference between the termination date reported by the mother and the index child's birth date divided by 30.4 days. Dietary diversity was included in the model in relation to the four indicated age intervals to which different feeding recommendations apply (6 to http://www.selleckchem.com/GSK-3.html corresponding period. The food groups were the following eight: (i) grain products and tubers; (ii) legumes/nuts; (iii) milk products; (iv) flesh foods; (v) eggs; (vi) vitamin-A rich fruits and vegetables; (vii) other fruits and vegetables and juices; and (viii) fats/oils. This categorization of foods was chosen so that a higher total score would likely reflect greater consumption of foods of higher nutrient density, such as animal source foods (three categories) and fruits and vegetables (two categories).
