Previous studies, mainly among populations with high consumption of seafood, have suggested that increased marine n-3 polyunsaturated fatty acid (PUFA) intake during pregnancy promotes longer gestation and higher birth weight. Few studies have isolated the contribution of fetal growth to birth weight. Using data from 2,109 pregnant women in Massachusetts enrolled in Project Viva from 1999 to 20...

BACKGROUND Recent steep declines in child mortality have been attributed in part to increased use of contraceptives and the resulting change in fertility behaviour, including an increase in the time between births. Previous observational studies have documented strong associations between short birth spacing and an increase in the risk of neonatal, infant, and under-five mortality, compared to ...

The evidence is limited on the relationship between reproductive factors and bladder cancer (BC). We studied 1,292,462 women who had a first and singleton delivery between 1 January 1978 and 31 December 1987. Each woman in the study cohort was tracked from their first childbirth to 31 December 2009. Vital status of the women was determined by crosswalking records with a computerized mortality d...

This study was designed to investigate causes of culling in industrial dairy herds in Fars province and to describe the pattern of reason-specific culling with respect to age of animal and interval from calving to culling. A total number of 9 dairy herds were selected for the study and information about culling reasons, birth date, last calving date and culling date was collected for culled cow...

OBJECTIVE This paper examines the association between birth intervals and infant and child mortality and nutritional status. METHODS Repeated analysis of retrospective survey data from the Demographic and Health Surveys (DHS) program from 17 developing countries collected between 1990 and 1997 were used to examine these relationships.

in this research a comparative study has been made between case and control groups. the cases were low birth weight newborns (under 2500 gr) and the controls were normal berth weighing 2500 gr or more at birth. four groups of birth weight were considered as follows: very low birth weight, low birth weight, moderately low birth weight and normal. the data were collected over a period of 8 months...

Antenatal corticosteroids (ACS) are part of the standard care for women at risk premature birth to reduce adverse neonatal outcome. Neonatal benefits optimized when ACS administered 2-7 days before delivery. Less is known about a shorter administration-to-birth interval less than 48 hours. We assessed association between short Corticosteroid Administration-to-Birth Interval and A retrospective ...
