background: in recent years, the study of birth intervals has been a main determinant of the levels of fertility in the populations, as it is associated with rates of fertility and population growth. objective: the purpose of this study was to firstly apply survival analysis for modeling of first birth interval and secondly to explore its determinants. materials and methods: in a cross sectiona...

background: this study aimed to assess the incidence and survival rates of neonates weighing less than 2500g for duration of the first 28 days in an iranian community. methods: in this prospective longitudinal study, all neonates with birth weight less than 2500g were selected from the list of all neonates born in the only public-sector referral hospital, for a six months period. the weight of ...

The data on 6772 growth records of Sirohi goats maintained at All India Coordinated Research Projecton Sirohi goat at Livestock Research Station, Vallabhnagar, Udaipur, India, and recorded between 2004 and 2016, were analysed to study the growth related traits and their genetic control. The overall least squares means of body weight at birth, W3M, W6M, W9M, W12M, were 2.34 ± 0.03, 12.44 ± 0.19,...

the data were collected from 1992 to 2009 in burri, white boni and black boni sheep maintained at the regional research station in the central highlands of yemen. data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. the least square means for body weights (bw) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

background: birth weight is considered as the most important index of neonates' growth as well as the most important determinant of infants' mortality. this study was conducted to investigate the growth pattern in normal, low and very low birth weight neonates for 18 months in the health care centers of isfahan, iran. materials and methods: in a cross-sectional and retrospective study, 214 neon...

objective:mold contamination of cakes and the possibility of mold growth can pose a serious health problem. bakery products include various ingredients, which regularly contain molds. these microorganisms on cakes can come from the air, contaminated packaging materials and other sources.methods: in this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...

BACKGROUND Birth weight for gestational age is a widely-used proxy for fetal growth. Although the need for different standards for males and females is generally acknowledged, the physiologic vs pathologic nature of ethnic differences in fetal growth is hotly debated and remains unresolved. METHODS We used all stillbirth, live birth, and deterministically linked infant deaths in British Colum...
