A comparison of mortality and morbidity pattern of hospital admissions of children under 14 years during 1966-68 and 1977-81 has been made. Annual admission rate has increased from 1515 to 2515, which is in proportion to the population increase of 3 lacs from 1966 to 1981. Recently more than 70% were discharged within a week as against 52% during 1966-68, indicating a faster turnover and a need for more beds. Protein energy malnutrition, infections and diarrhoea with dehydration were main killers. The pattern of mortality and morbidity has not much changed from 1966 to 81 but mortality rates at all ages have considerably declined in recent years (neonatal, post neonatal, preschool and school). Measures to decline it further have been discussed. The data should be of interest to those engaged in planning health strategies and to teachers in defining priorities in Medical education.

Experience in the control of tetanus neonatorum (TN) in a rural area is presented. TN was reduced by training of dais, increasing the coverage of tetanus toxoid to pregnant women and distribution of presterilized delivery kits to pregnant ladies for use by birth attendants. The problems of untrained birth attendants, effectiveness of tetanus toxoid coverage and place of delivery are discussed.
A total of 18,334 live births and 376 neonatal deaths at the University of Benin Teaching Hospital were analyzed. The neonatal mortality rate has declined significantly from 49.5/1000 in 1974 to 16.4/1000 live births in 1981. The decrease mainly resulted from the reduction of mortality of full size infants (greater than 2500 g) and deaths resulting from perinatal asphyxia. Further reduction may be anticipated if careful attention is paid to the management of breech delivery and if a more intensive care for low birth weight infants is provided.
In the Perinatal Unit of the New Jersey Medical School, Newark the combined neonatal mortality and stillbirth rates declined from more than 51 per 1000 to less than 17 per 1000 between 1971 and 1983. This change is comparable to the reduction of perinatal mortality rates nationwide since the Second World War. Because the improvement in the fetal and neonatal survival rates occurred in a static population and against well identifiable changes in the structure, equipment, policies and management patterns of the obstetric unit, it was possible to assess the impact of various factors upon perinatal outcome. In the environment of this institution adherence to conservative concepts of obstetric management, avoidance of manipulative and extraction procedures, an increase of the rate of cesarean sections from about 7 to 15% and emphasis upon infection control appeared to be the crucially important factors. Antepartum sonography and fetal stress and non-stress testing significantly impacted upon the results. The role of intrapartum electronic monitoring was less clearly definable and seemed to be effective only in the hands of experienced physicians. The results did not seem to be adversely affected by the fact that the program de-emphasized invasive procedures, including fetal scalp pH sampling.
To compare the seasonal variation in total mortality and deaths from cardiovascular, respiratory, and malignant disease, data were collected from North-East Scotland (Grampian region) and Kuwait. Seasonal differences were similar, in both timing and degree, for total mortality and deaths from circulatory disease, but were greater in Kuwait for respiratory disease. Peak mortality was during winter in both areas: in Grampian, when the climate is most uncomfortable, and in Kuwait, when the climate is at its most comfortable. Socioeconomic changes in Kuwait have been accompanied by a rapid fall in the degree of seasonality (deseasonality) for both total and infant mortality. These findings suggest that mortality peaks in winter, not because of a seasonally low temperature, but because of a seasonal fall in mean temperature irrespective of the annual mean temperature.
Neonatal mortality and causes of death at King Fahd Hospital of the University in Al Khobar, Saudi Arabia from June 1981 to May 1986 were analysed. The overall neonatal mortality rate declined from 15.6 to 8.1/1000 live births (LB), and after excluding lethal malformations mortality fell from 14.0 to 5.6/1000 LB. The reduction in mortality was most marked in infants weighing 1500 g or less, among whom mortality fell from 92.3 to 33% (P less than 0.001) during the 5-year period. Further, when annual variation in the very low birthweight rate was eliminated, a reduction in the mortality risk ratio from 1.47 to 0.81 was demonstrated. These significant reductions in mortality appear to be related to the establishment of neonatal intensive care. Major identified causes of death amenable to modern perinatal care were hyaline membrane disease, birth asphyxia, meconium aspiration and septicaemia.
Perinatal and neonatal mortality rates, in the Greater Harare Maternity Unit, which showed a modest decline from 1980 to 1985, have rise dramatically since then. Half of the rise in neonatal mortality rate is due to increased numbers and an increased mortality rate in babies of birth weight less than 1001g. There is also an increase in the numbers of deaths of large babies. There is a strong case for a broad-based on-going enquiry into the reasons for such changes.
A study of 233 neonatal deaths out of 30910 livebirths over an 8 year period in the Toa Payoh Hospital is done. The Hospital has since ceased providing obstetric and neonatal intensive services from April 1990 due to restructuring of hospital care. The Neonatal Mortality Rates (NNMR) from 1982-1989 ranged from 6.52 to 9.55 and there was no significant fall in trend (p = 0.13). One hundred and thirteen (48.5%) neonates who died were below 1500gm (VLBW). Various causes of neonatal deaths were examined and there was a decline in respiratory distress syndrome (RDS) death rates (p less than 0.0002). Deaths due to asphyxia (p greater than 0.05) and infections (p greater than 0.05) have not declined significantly over the same period. It is also observed that less VLBW babies died over this 8 year period and the VLBW mortality rates (p less than 0.02) have declined. However, the congenital malformation mortality has also not declined significantly (p = 0.92) though early study (1972-1981) showed an increasing trend of malformation deaths among total neonatal deaths (p less than 0.02). Improvement in VLBW and RDS management has not contributed to a significant decline in NNMR. It is observed that more VLBW babies were born during this 8 year period (p = 0.01) especially so in the less than 1000 gm group (p = 0.0005) and the survival of VLBW babies has improved (45.5% to 75.8% alive) as a result of advances in neonatal intensive care. The reasons for increase in incidence of VLBW births in the past few years are not known.(ABSTRACT TRUNCATED AT 250 WORDS)
Studies on trends in infant mortality and its constituent elements of early neonatal, late neonatal and postneonatal death, in developed and developing countries, point to ways of making further progress towards the target of infant mortality rates not exceeding 50/1000 live births in all countries by the year 2000.
Although the infant mortality rate (IMR) has reduced by 50% during the past century, it compares poorly with the advanced countries and some developing countries. The observed fall in IMR has been mostly in post-neonatal mortality, with the result that neonatal deaths now account for over 60% of all infant deaths. The overall perinatal mortality rate (PMR) in India is still over 50 per 1000 and has shown virtually no decline during the past decade, However, PMR differs widely in different states, urban/rural areas, different hospitals and so on. PMR is seen to correlate better with social development than economic development of the representative community. The causes of perinatal deaths suggest poor health of mother and poor health facilities and are hence potentially preventable. Various studies have shown that PMR can be significantly reduced within a short span of time. The registration of vital statistics continue to be highly unsatisfactory especially in rural areas.

Study of the effects of malaria chemoprophylaxis given during pregnancy on birthweight and investigation of the influence of birthweight on child survival suggest that, in a rural area of The Gambia, chemoprophylaxis given during pregnancy might reduce infant mortality by about one-fifth in the children of primigravidae but by less than 5% in the children of multigravidae. In malaria endemic areas, primigravidae should be protected against malaria not only for their own sake but also for that of their infants.
In 1984 and again in 1985, systematic surveys were undertaken to evaluate infant mortality and childhood nutritional status among the Afghan refugee population in Pakistan. The entire Afghan refugee population under the administration of the United Nations High Commissioner for Refugees was sampled. Infant mortality rates were estimated to be 156 per 1000 for 1984 and 119 per 1000 for 1985. A decline was also suggested in neonatal mortality rates from 61 per 1000 for 1984 to 46 per 1000 for 1985. For neither infant nor neonatal mortality was the difference statistically significant. Improvements were seen in the percentage of children who died before their fifth birthday (22.5% in 1984 and 18.8% in 1985), in the percentage of children who were malnourished (3.5% in 1984 and 2.3% in 1985), and an increase in the percentage of children above the WHO/NCHS/CDC weight-for-height reference median (26% in 1984 and 35% in 1985). Diarrhoea was the most frequently reported cause of death for both years and was a particularly important cause of death among one-year-old children. In 1985, measles was related to 24% of the deaths and neonatal tetanus to 9% of the deaths, an increase from 8% for measles and 6% for tetanus in 1984.
Perinatal deaths, comprising stillbirths and deaths during the first week of life, were monitored over the eight-year period 1979 to 1986 in a rural Bangladeshi population of 196,000. The perinatal mortality rate was 75 per 1000 total births. The rate was 13% higher in males than females. Stillbirth and early neonatal mortality rates were 37 and 38 per 1000 total births, respectively. The major causes of perinatal deaths are presented, as well as some of the maternal determinants. During the period under study, perinatal mortality declined regularly and significantly over time in an area covered by an intensive Family Planning and Health Services programme, but not in the adjacent control area. This raises the issue of the impact of such a programme upon perinatal mortality, and the need to include a strong maternity care component into primary healthcare strategies if further reductions of perinatal mortality are to be achieved.
The infant mortality rate (IMR) in the Jewish and Arab populations in the Western Galilee was studied during the 2-year period 1985-86, and compared with those of previous surveys conducted since 1964-65. The IMR declined steadily during the two decades, from 33.6 to 8.5/1,000 in the Jewish population and from 49.2 to 18.2/1,000 in the Arab population. The decline was noted in both neonatal and postneonatal periods. Analysis of the causes of death showed that enteric and respiratory infections ranked high in the first and second surveys (1964-65 and 1970) and decreased to a low level in both population groups in recent years, but were still relatively high among Arab infants living in villages. The decrease in the IMR seems to be the result of an improvement in the general living conditions of the population and the efficiency of the health services.
