Fertility is one of the responsible factors for the growth of human population. The demographers have given priority to understanding of the determinants of fertility through statistical techniques. Analytical models are suitable and appropriate tools and are widely used for better understanding of the phenomenon of the human fertility behavior. In other words, these models are useful in descri...

More than 1200 St Helenian schoolchildren were studied in 1973 and 1978 to determine how social factors affected growth. The association of short stature with large family size was confirmed and shown to be concentrated in the earlier members of the sibship. This was independent of birth interval. Association between birth interval and stature was most pronounced for the spacing following the i...

This paper demonstrates the approach of extending "date of last birth" (DLB) techniques to parametric models. Estimators for Coale-Trussell M and m parameters are constructed from open interval lengths. A new procedure was applied to Brazilian census data, producing maps and spatial statistics for "births last year" (BLY) and DLB m estimates in 723 municipalities in Minas Gerais. DLB estimat...

In renewal theory approach, it is well known that the limiting forms of the probability density function of backward recurrence time and forward recurrence time which are similar to open birth interval and forward birth interval are identical on the assumption that the renewal densities do not change over time. The forward birth interval defined as the time between the survey date and the date ...

background: iron deficiency anemia (ida) during pregnancy is a common nutritional disorder with adverse effects for the baby, such as premature birth and low birth weight, and the mother, such as cardiovascular symptoms and reduced physical and mental strength. therefore, identifying factors affective on ida will assist the improvement of the health of the mother and fetus. this study aimed to ...

A dynamic panel data model of neonatal mortality and birth spacing is analyzed, accounting for causal effects of birth spacing on subsequent mortality and of mortality on the length of the next birth interval, while controlling for unobserved heterogeneity in mortality (frailty) and birth spacing (fecundity). The model is estimated using micro data on about 29000 children of 6700 Indian mothers...

OBJECTIVE To determine the relationship of interpregnancy interval with maternal and offspring outcomes. DESIGN Retrospective study with data from the Perinatal Information System database of the Latin American Centre for Perinatology and Human Development, Uruguay. SETTING Latin America, 1990-2009. POPULATION A cohort of 894 476 women delivering singleton infants. METHODS During 1990-2...
