OBJECTIVE To determine whether the interpregnancy interval (IPI) is associated with the risk of autism in subsequent births. METHODS Pairs of first- and second-born singleton full siblings were identified from all California births that occurred from 1992 to 2002 using birth records, and autism diagnoses were identified by using linked records of the California Department of Developmental Ser...

The effect on intestinal macromolecular absorption capacity and immunoglobulin G (IgG) transfer of feeding sow colostrum at different intervals and in different quantities to newborn pigs was studied. An amount of 15 ml/kg body weight (BW) colostrum was fed at 3 (treatment 3–15), 6 (treatment 6–15) or 12 (treatment 12–15) h intervals, respectively, starting 0–4 h after birth for 24 h; or 30 ml/...

BACKGROUND Currently, family planning metrics derived from nationally-representative household surveys such as the Demographic and Health Surveys (DHS) categorise women into those desiring to space or limit (permanently stop) births, or according to their age in the case of young women. This conceptualisation potentially ignores a large and growing group of young women who desire to delay a fir...

The present experiment focuses on the evaluation of behavior Holstein calves in first two hours after birth. research took place at Slovak University Agriculture Farm Oponice. calf sample consisted 11 individuals. lying, standing, moving were scored and number attempts to lift head, latency head lifting, stand up up, ears shaking. Behavior was evaluated by next traits: total duration standing m...

Advanced maternal age at birth is considered a major risk factor for birth outcomes. It is unclear to what extent this association is confounded by maternal characteristics. To test whether advanced maternal age at birth independently increases the risk of low birth weight (<2,500 g) and preterm birth (<37 weeks' gestation), we compared between-family models (children born to different mothers ...

OBJECTIVE We examined the relationship between extreme parity and risk for stillbirth in the United States. METHODS Singleton deliveries at 20 weeks of gestation or later in the United States from 1989 through 2000 were analyzed. Risk for stillbirth in women with 1-4 (moderate parity, category I), 5-9 (high parity, category II), 10-14 (very high parity, category III), and 15 or more (extremel...

OBJECTIVES To evaluate preterm birth (PTB) for Inuit and First Nations vs. non-Indigenous populations in the province of Québec, Canada. STUDY DESIGN Retrospective cohort study. METHODS We evaluated singleton live births for Québec residents, 1981-2008 (n = 2,310,466). Municipality of residence (Inuit-inhabited, First Nations-inhabited, rest of Québec) and language (Inuit, First Nations, Fr...

Objective. To characterize trends in chorioamnionitis (CAM) by maternal race/ethnicity and gestational age. Study Design. We examined trends in CAM from 1995-2010 among singleton births in all Kaiser Permanente Southern California hospitals (n = 471,821). Data were extracted from Perinatal Service System and clinical utilization records. Gestational age- and race/ethnicity-specific biannual dia...
