Between 1980 and 1989 we carried out fortnightly demographic surveillance in a random sample of people living in Goroka town, periurban areas and rural areas in the Lowa and Asaro Census Divisions, all within 1 1/2 hours' drive of the town in the Asaro Valley, Eastern Highlands Province. Cause of death was determined by verbal autopsy supplemented by any available health service information. Crude death and birth rates were 10 and 32 per 1000 person-years, respectively, in 59,906 person-years at risk. The standardized mortality ratio increased with increasing distance from town. Life expectancy at birth was 57 years for males and 55 years for females. The stillbirth rate was 19 per 1000 births, neonatal and infant mortality 21 and 60 per 1000 livebirths, respectively, and 1-4-year mortality 9 per 1000 person-years. Maternal mortality was 3 per 1000 births. Neonatal and infant mortality were respectively 7 and 3 times as high in Asaro Census Division as in Goroka town. Acute lower respiratory tract infections accounted for 22% of all deaths, chronic obstructive lung disease 10%, trauma 8% and gastroenteritis/dysentery 7%. 76% of deaths occurred at home and 44% of people who died had no treatment during their terminal illness. Health services were used most frequently by urban dwellers and by the young. To reduce mortality, a political commitment to provide functioning health services in rural areas is needed; regular supervision of health staff, ensuring the safety of staff and their families, availability of antibiotics as near people's homes as possible and regular mobile maternal and child health clinics are essential. Health education should include recognition of signs of severe disease and the importance of seeking treatment early. In view of high maternal and neonatal mortality, user fees should be waived for pregnant women.

A morbidity study of diarrhoea covering 1926 children aged less than 5 years was carried out in Goroka town and the Lowa and Asaro Census Divisions, Eastern Highlands Province between 1986 and 1989. The study involved weekly demographic surveillance of the total population and morbidity surveillance of children by lay reporters who enquired about the presence or absence on any of the preceding 8 days of a range of symptoms associated with diarrhoeal and respiratory diseases. A three-day symptom-free period was used to define distinct episodes of diarrhoea. The average number of episodes/child-year for all children in the study population was 3.0. Boys suffered a significantly higher incidence of diarrhoea under 48 months of age than girls (4.4 episodes compared to 3.6/child-year). Incidence was highest among those aged 6-17 months (5.5/child-year) with a rapid decline after age 35 months. Incidence of diarrhoea was highest in the more remote Asaro Census Division and was higher in periurban areas than in Goroka town. Incidence also varied significantly between villages, some villages experiencing up to 10 times the incidence of diarrhoea found in Goroka town. The incidence of diarrhoea was significantly higher in January than at other times of year. Duration of diarrhoea varied with age, the longest duration being an average of 4.7 days in the 12-17 months age group. In order to reduce diarrhoea morbidity, it is necessary to improve access to water, encourage improved hygiene practices and breastfeeding and warn people about the risks of sleeping with pigs.
