The association between meteorologic temperature and sudden infant death syndrome was investigated in the 1982-1983 North Carolina birth cohort. Maximum daily temperatures recorded at weather stations in the subject's county of residence for each day of the first year of life were entered into hazards models as time-dependent covariates. Risk ratios for a maximum temperature of < or = 53 degree...

BACKGROUND Short birth intervals are known to have negative effects on pregnancy outcomes. We analysed data from a large population surveillance system in rural Bangladesh to identify predictors of short birth interval and determine consequences of short intervals on pregnancy outcomes. METHODS The study was conducted in three districts of Bangladesh - Bogra, Moulavibazar and Faridpur (popula...

OBJECTIVE This study assessed the influence of socioeconomic position at 12 years of age (SEP-12) on the variability in cesarean rates later in life. METHODS As part of the Portuguese Generation XXI birth cohort we evaluated 7358 women with a singleton pregnancy who delivered at five Portuguese public hospitals serving the region of Porto (April/2005-September/2006). Based on the twelve items...

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 ...

ethiopia's childhood mortality has continued to decline although at a swift pace. the drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends in ethiopia.  data from the ethiopian demographic and health surveys 2000 and 2005 were used. indirect estimation of brass and trussell's methods were adopted. selected demog...

per birth interval were those published for the following interval (eg, 2005 estimates used for 1996e2000 births). Results From 1986 to 2000, 321 DBMD males resided in an MD STARnet site during one or more birth intervals, which produced a prevalence of 1/5000 residents. Race/ethnic-specific prevalence tended to be higher for Hispanics than non-Hispanic whites or African-Americans. Prevalence t...

The timing of marriages, first birth interval and the prevalence of premarital conception (PMC) among women of successive birth cohorts in one rural county in Yunnan, China, were examined. Detailed pregnancy histories were collected for 1,336 women aged 15-64 years using a Life History Calendar. The rising marriage age and shorter first birth interval correspond to over-all changes in the Chine...

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. The key independent variable is the length of the precedin...
