A survey of 411 household heads was undertaken in Gokwe district, Zimbabwe, to assess villagers&apos; knowledge, practices and perceptions about malaria and their implications for malaria control Our results show that although the government has sustained an annual indoor insecticide spraying programme for over four decades, about 50% of respondents did not adequately understand its purpose, with 26% believing that the programme was intended to kill domestic pests, not including mosquitos. During the 1991-92 spraying cycle, 72% of the villagers had their homes sprayed. However, 21% of such villagers refused to have some rooms in their homes sprayed. Householders&apos; understanding of the function of the spraying programme was significantly related to their compliance with it (P < 0.05). A total of 82% of respondents reported not taking any measures to protect themselves from malaria, Taking preventive measures was significantly related to knowledge of the causes of malaria (P < 0.05). The study shows the importance of involving communities in a control programme intended to be to their benefit and of informing them about available options for protection against malaria., Introduction Malaria is a serious public health problem in Zimbabwe. Plasmodium falciparum, responsible for the most severe and potentially fatal form of the disease, accounts for 97% of malaria infections [...]

Teenage pregnancy is extremely common in South Africa. Whilst its 'problematic' nature is a subject of debate, it reflects a pattern of sexual activity which puts teenagers at risk of HIV. Currently one in five pregnant teenagers is infected with the virus. This creates a new imperative to understand teenage pregnancy and the pattern of high risk sexual activity of which it is one consequence. This was an exploratory study undertaken to investigate factors associated with teenage pregnancy amongst sexually active adolescents in an urban and peri-urban context. The study used a matched case control design, with 191 cases and 353 school or neighbourhood, age-matched controls. Subjects were under 19 years and recruited from township areas of Cape Town. A structured questionnaire was used to obtain information on socio-economic factors, contraceptive knowledge and use, and sexual behaviour. Conditional logistic regression was used to analyse the relationship between teenage pregnancy and the factors investigated. The results presented focus on relationship dynamics and their association with the risk of pregnancy. Both groups of teenagers had been dating for a mean of two and a half years and about half were still with their first sexual partner. The partners of the pregnant teenagers were significantly older, less likely to be in school and less likely to have other girlfriends. The pregnant teenagers were significantly more likely to have experienced forced sexual initiation and were beaten more often. They were much less likely to have confronted their boyfriend when they discovered he had other girlfriends. Multiple modelling shows that both forced sexual initiation and unwillingness to confront an unfaithful partner are strongly associated with pregnancy and also related to each other. We argue that the associations are mediated through unequal power relations within the relationship which are reinforced by violence. We further discuss indicators of greater intimacy within relationships of the pregnant teenagers which may suggest that more of the pregnancies were wanted than was suggested. Both of these conclusions pose critical challenges for health promoters.

Motivation: Teenage pregnancy is an important health and social problem in South Africa. So far research on adolescent sexual activity has been almost exclusively descriptive; as a result there is considerable knowledge about practices of adolescents in general and outcomes of their pregnancies, but very limited understanding of factors that place particular adolescents at increased risk of teenage pregnancy. Without this understanding, our ability to intervene effectively to reduce teenage pregnancy rates is limited., Objective: To undertake an exploratory study to investigate risk factors for teenage pregnancy among sexually active adolescents in an urban and peri-urban context., Methods: The study used a matched case-control design, with 191 cases and 353 age-matched controls from the same school or neighbourhood. Subjects were under 19 years of age and were recruited from township areas of Cape Town. A structured questionnaire was used to obtain information on socio-economic factors, contraceptive knowledge and use, and sexual behaviour. Conditional logistical regression was used to analyse the relationship between teenage pregnancy and the factors investigated., Results: Teenage pregnancy was found to be most strongly associated with having frequent sex (risk ratio (RR) 30.81) without reliable contraceptive protection (RR 24.35), forced sexual initiation (RR 14.42), not owning a television set (RR 10.33), larger household size (RR 2.44), not living in a brick house (RR 5.09), not living with the biological father (RR 3.26), talking openly about sex with a boyfriend (RR 4.72), and perceiving most friends to be pregnant (RR 4.38)., Conclusions: The findings suggest associations between the promotion of sexual health among adolescents and broader social development and promotion of gender equality. Although further research is needed, it is likely that important foci for short-term strategies should include developing assertiveness, enhancing decision-making competence, and promoting contraception and condoms as part of comprehensive sexual and reproductive health educational interventions.

Setting: Study conducted in a suburb of Cape Town, South Africa., Objective: Comparison of successful tuberculosis treatment outcome rates between self supervision, supervision by lay health worker (LHW), and supervision by clinic nurse., Methods: Open, randomised, controlled trial with intention-to-treat analysis., Results: All groups (n = 156) achieved similar outcomes (LHW vs. clinic nurse: risk difference 17.2%, 95% confidence interval [CI] -0.1-34.5; LHW vs. self supervision 15%, 95%CI -3.7-33.6). New patients benefit from LHW supervision (LHW vs clinic nurse: risk difference 24.2%, 95%CI 6-42.5, LHW vs. self supervision 39.1%, 95%CI 17.8-60.3) as do female patients (LHW vs. clinic nurse 48.3%, 95%CI 22.8-73.8, LHW vs. self supervision 32.6%, 95%CI 6.4-58.7)., Conclusions: LHW supervision approaches statistically significant superiority, but fails to reach it most likely due to the study's limitation, the small sample size. It is possible that subgroups (new and female patients) do well under LHW supervision. LHW supervision could be offered as one of several supervision options within TB control programmes.

Objectives: (i) To ascertain what proportion of patients attending the general medical outpatient service at Red Cross War Memorial Children's Hospital (RXH) could safely be managed at peripheral primary care facilities; and (ii) to measure the effect of the introduction of free health care for children under 6 years of age on requirements for levels of care ranging from home to super-specialist referral centres., Design: Prospective survey of patients attending on a stratified, randomised sample of 7 days in March 1994 (N = 1 962) and again in November 1994 (N = 1 404)-before and after the introduction on 6 June 1994 of free care for children under 6 years of age., Setting: The general outpatient department of an academic/referral children's hospital., Patient Selection: All patients attending the outpatient department on the study days (7h00 to 6h59 the following day), excluding those who were referred, returning for follow-up, attending a specialist clinic or attending the surgical outpatient department. QUESTIONNAIRE: The questionnaire completed by medical officers recorded the following: patient's name, folder number, date and time of arrival, whether referred, clinic, treating doctor, disposal, diagnoses, home suburb and the level of care required: (i) home: (ii) clinic without a doctor; (iii) clinic with a doctor; (iv) hospital with non-specialists; (v) hospital with general paediatricians; or (vi) super-specialist hospital., Main Results: In March 1994 the percentages of unreferred patients requiring the 6 levels of care defined for the study were 0.3, 25, 62, 8, 3 and 1, respectively. In November 1994 the percentages were 4, 41, 43, 8, 4 and 1. The graph of the number of patients seen at the outpatient department each month shows a large month-to-month variation but the trend is clearly towards an increase., Conclusions: The general medical outpatient department at RXH provides care to a large number of children, 48% of whom are unreferred. Of the unreferred patients 95% could be treated (more appropriately for the health services and more conveniently for their families) at a local primary health care facility. The situation has been aggravated by the introduction of free care for children under 6 years of age, who constitute 83% of the unreferred workload.
