ABSTRACT
The study was conducted to investigate the association between perinatal mortalityand factors relating to nutrition and infections in a rural population in northern Tanzania. A cohort of 3,618 women attending antenatal clinics was registered with background information and the results of antenatal examinations, and followed up after delivery. Stillbirths and neonatal deaths were identified and traced for an interview with the closest relatives. No information on outcome of pregnancy was obtained for seven women, and incomplete information was obtained for 99. The perinatal mortality rate was 27/1,000 births [95% confidence interval (CI) 22/1,000-33/1,000]; 44% were early neonatal deaths; and 56% were stillborn. There was an increased risk of perinatal death among babies with low birth-weight [for babies weighing 2,000-2,499 g, adjusted odds ratio (AOR) 5.8, 95% CI 2.1-15.8, babies below 2,000 g AOR 45.7; 95% CI 18.3-114.1], babies of women with a small arm circumference (below 23 cm, AOR 5.3, 95% CI 1.3-22.2), babies of women with positive VDRL serology (AOR 5.1, 95% CI 1.0-25.7), babies of mothers who had previously lost a baby (AOR 1.9, 95% CI 1.1-3.2), and among babies of nulliparous women (AOR 1.7; 95% CI 1.0-3.0). Infections and nutritional deficiencies should be addressed at antenatal clinics.
