ABSTRACT. The patterns of breastfeeding and weaning were studied in 4 groups of Saudi children: Privileged urban children; children representing the average urban population; less privileged urban children, and rural children from 3 different areas. The data represented retrospective and actual information and were analyzed according to the life table technique. The median duration of breastfeeding of rural, urban low, urban average and urban privileged children was 17.8 months, 10.8 months, 7.5 months and 2.1 months, respectively. In all groups the rate of breastfeeding was lower in young compared with old mothers. Thus the median duration of breastfeeding was 11.7 months for rural mothers <23 years and 23.6 months for mothers >31 years. Corresponding figures for urban low mothers were 3.4 months and 11.4 months, respectively. By one month 52 percent of privileged and 42 percent of urban low children were started on bottle. By contrast, 26 percent of rural children were started on bottle at 6 months, At 6 months, 6 percent of rural children were started on any kind of solid foods compared with 90 percent of privileged children; at 12 months the figures were 33 and 96 percent, respectively. The data indicated a successive decline in the duration of breastfeeding with increasing affluence, and late introduction of weaning foods to rural children.

Mothers who delivered in a large Maternity hospital and who represented a large proportion of the obstetric population in Riyadh are described. The mothers were characterized by a high material standard of living, by adequate energy reserves at confinement, by a low rate of pregnancy complications and preterm birth, and by the absence of smoking and of hard physical work during pregnancy. The mothers were also, however, characterized by pregnancies occurring at the extremes of the reproductive age, by short birth intervals, by short maternal stature, by low educational attainment, by poor utilization of antenatal services and by a high rate of previous infant loss, that is by characteristics previously found to consitute riskfactors for adverse perinatal outcome.

ABSTRACT. The time, cause and avoidahility of perinatal deaths were analyzed in infants who were delivered in the main Maternity hospital in Riyadh and who represented a large proportion of all births in the city. The crude perinatal mortality rate was 39.8 per 1000 births. Of all deaths 53 percent occurred either intrapartum or within 24 hours of birth. The mortality rate in this time period was 9 times higher, and the intrapartum mortality rate 16 times higher than the corresponding Swedish rates. The causes of death were classified according to Wigglesworth. Of all deaths, 37 percent were due to asphyxial conditions in labor, 32 percent to conditions associated with preterm birth, and 17 percent to malformations. The perinatal mortality rates caused by asphyxia, preterm birth and malformations were 14.7, 12.6 and 6.7 per 1000 births, respectively. 75 percent of infants who died from asphyxia were born at term, and nearly half of the preterm deaths were associated with severe asphyxia at birth. Avoidable factors were found in 74 percent of the deaths. The high rate of asphyxia indicated deficiences in the obstetric management and a high priority should be given to the strengthening of the obstetric service.

ABSTRACT. The size at birth was assessed of Saudi infants who were delivered in the main Maternity hospital in Riyadh and who represented a large proportion of infants born in the city. The mean (SD) weight, length and head circumference at birth of Saudi singletons were 3226 (534) g, 49.5 (2.0) cm and 34.5 (1.5) cm, respectively. Of all infants 5.9 percent were born preterm. The proportion of low birthweight infants was 7.9 percent, of which 44 percent were born at or past term. Teenage mothers had a low birthweight rate of 15.2 percent and primipara of 13.9 percent, however. Of all singletons 2.2 percent were small for gestational age and 3.7 percent of term infants had a Ponderal index <3rd percentile of the standard. During the final weeks of gestation the fetal growth rate was similar to that of Western populations. Compared with other developing countries the birth weight distribution was favorable and seemed to be influenced to a smaller extent than in these countries by socioeconomic and environmental factors.
