Sero-prevalence to hepatitis B and C virus infection in refugees from Mozambique in southern Africa.
Serological markers for evidence of past exposure to hepatitis B virus (HBV) and hepatitis C virus (HCV) were investigated in a cohort of refugees from Mozambique. Serological markers for past exposure to HBV were detected in 56% of the population and, in addition, 13.2% carried the HBV surface antigen. ⋯ Only one anti-HCV antibody positive individual was positive for HBsAg. Immunity to rubellavirus had reached 85% by 11 years of age.

A survey was conducted in the Cape Town metropolitan area in 1990 to determine the dietary intake and anthropometric status of 3-6 year-old African children (N = 163). Dietary data obtained from 24-hour recalls revealed that mean energy intake (5200 kJ) was low and that mean intakes of most nutrients fell considerably below the recommended dietary allowances (RDAs). ⋯ Anthropometric profiles expressed in terms of the National Centre for Health Statistics' (NCHS) standards, revealed evidence of growth retardation and wasting in this population, coexisting with emergent obesity. The development of a nutrition and health policy to address the problems of both deficit and excess represents a pressing challenge.

A review of 114 thoracic empyema cases attended in the thoracic unit of the Muhimbili Medical Centre from July 1986 to July 1990 is presented. 87.7% of the cases were males. Their ages ranged from 9 to 79 years with a mean of 32 years. ⋯ The duration of hospital stay ranged from 2-8 months with a mode around 3.5 months. A 7% mortality was noted.

A community-based survey on maternal mortality was carried out in the Ejisu health district of Ghana in January and February 1990 to identify all women who died in pregnancy, delivery or the puerperium from January 1985 to December 1989, determine their characteristics, the presumptive causes of death and related factors. Forty-four women who died in pregnancy, delivery or the puerperium were identified over the stated period. 59% were aged between 20 and 34 years. Eighty-two percent were married and sixty-six percent had at least primary education. ⋯ Thirty-four percent of the women who died did not attend any antenatal clinic. The actual number of deaths may be underestimated due to the sampling method used and the difficulties encountered in linking survey data with hospital records. Based on the survey findings and other related PMM research, plans have been developed to reduce maternal mortality in the district as outline in the conclusion.

Comparative Study
Demographic and AIDS-related characteristics of consenters to a population-based HIV-survey: results from a pilot study in Arusha, Tanzania.
The aim was to compare demographic and AIDS-related characteristics of people who consented to HIV-testing as part of a population survey with those who did not consent to HIV-testing. Subjects, aged 15-54 years, living in ten randomly selected clusters of households in one ward of Arusha town were asked to participate in a structured interview and to provide a blood sample for HIV-testing. Measurements included demographic variables and AIDS-related factors, such as knowledge of AIDS and sexual behaviour, and HIV-testing with Western Blot confirmation. ⋯ No other demographic or AIDS-related differences were observed between HIV-test consenters and non-consenters. At least in this pilot, non- consenters did not appear to be at any higher risk for HIV-infection than the consenters. Future population-based HIV-surveys might have to compromise on maximizing participation rate in order to secure informed, non-coerced consent from participants.
