Project ACCLAIM: Intervention Effect on Community Knowledge, Attitudes and Beliefs of Maternal and Child Health and HIV/AIDS in Eswatini, Uganda and Zimbabwe.

The ACCLAIM Study aimed to assess the effect of a package of community interventions on the demand for, uptake of, and retention of HIV-positive pregnant/postpartum women in maternal and child health (MCH) and prevention of mother-to-child HIV transmission (PMTCT) services. The study occurred from 2013 to 2015 in Eswatini, Uganda, and Zimbabwe. The three interventions were: (1) a social learning and action component for community leaders, (2) community days, and (3) peer discussion groups. Household cross-sectional surveys on community members' MCH and PMTCT knowledge, attitudes, and beliefs were analyzed pre- and post-intervention, using MCH, HIV stigma, and gender-equitable men (GEM) indicators. We used t-tests to measure the significance of mean pre- vs. post-intervention score changes stratified by gender within each intervention arm and generalized linear models to compare mean score changes of the cumulative intervention arms with the community leaders-only intervention. Response rates were over 85% for both surveys for men and women, with a total of 3337 pre-intervention and 3162 post-intervention responses. The combined package of three interventions demonstrated a significantly greater increase in MCH scores for both women (diff = 1.34, p ≤ 0.001) and men (diff = 2.03, p < 0.001). The arms that included interventions for both community leader engagement and community days (arms 2 and 3)led to a greater increase in mean GEM scores compared to the community leader engagement intervention alone (arm 1), for both women (diff = 1.32, p = 0.002) and men (diff = 1.37, p = 0.004). Our findings suggest that a package of community interventions may be most effective in increasing community MCH/HIV knowledge and improving gender-equitable norms.

Comparison of HIV-positive women with children and without children accessing HIV care and treatment in the IeDEA Central Africa cohort.

Globally, women comprise half of all people living with HIV, but in sub-Saharan Africa, women are disproportionately affected. Data were obtained from 8419 HIV-infected women at enrollment into 10 HIV treatment programs in Cameroon, Burundi, and the Democratic Republic of the Congo as part of the Central Africa region of the International Epidemiological Database to Evaluate AIDS. We used chi-squared tests to determine if distributions between women with children differed from those without children, in regards to socio-demographic, behavioral and clinical characteristics. Logistic regression was used to determine if motherhood was associated with medication adherence. Of 8419 women, 81.7% had living children. The majority entered care through voluntary testing, and very few entered care through prevention of mother-to-child transmission programs. Women with children were older and more likely to be widowed, more likely to have no formal education and less likely to have attended university than those without children (p<0.05). Women without children were more likely to live in a home with electricity and potable water (p<0.05). There was no difference in adherence between these groups. However, women older than 50 years, those who reported no drug, tobacco, or alcohol use, and those with higher levels of formal education were more likely to report adherence along with those who had been on treatment for more than two years (p<0.05). As women account for a substantial proportion of HIV cases in sub-Saharan Africa, a broader understanding of their characteristics will inform testing, treatment, and support services. Though we did not find differences in adherence between women with children and those without children, we were able to identify other characteristics that may affect adherence. Further inquiry into the nuances of women living with HIV in sub-Saharan Africa is necessary to further understand their needs.

Increased risk of HIV-infection among school-attending orphans in rural Zimbabwe.

In Zimbabwe around 1.1 million children have been orphaned due to AIDS. We conducted a survey among school-attending youth in rural south-eastern Zimbabwe in 2003, and examined the association between orphaning and risk of HIV. We enrolled 30 communities in three provinces. All students attending Year 2 of secondary school were eligible. Each completed a questionnaire and provided a finger-prick blood specimen for testing for HIV-1 and HSV-2 antibodies. Female participants were tested for pregnancy. Six thousand seven hundred and ninety-one participants were recruited (87% of eligible); 35% had lost one or both parents (20% of participants had lost their father; 6% their mother; and 9% both parents). Orphans were not poorer than non-orphans based on reported access to income, household structure and ownership of assets. There was strong evidence that orphans, and particularly those who had lost both parents, were at increased sexual risk, being more likely to have experienced early sexual debut; to have been forced to have sex; and less likely to have used condoms. Fifty-one students were HIV positive (0.75%). Orphans were three times more likely to be HIV infected than non-orphans (adjusted odds ratio = 3.4; 95% confidence interval: 1.8-6.6). Over 60% of those HIV positive were orphaned. Among school-going youth, the rates of orphaning were very high; there was a strong association between orphaning and increased risk of HIV, and evidence of greater sexual risk taking among orphans. It is essential that we understand the mechanisms by which orphaned children are at increased risk of HIV in order to target prevention and support appropriately.

Efficacy and side effects of praziquantel treatment against Schistosoma haematobium infection among primary school children in Zimbabwe.

We examined the efficacy of praziquantel against Schistosoma haematobium among primary school children during a school-based deworming programme in the Burma Valley commercial farming area and the Nyamaropa rural areas in Zimbabwe, where the disease is highly endemic. Among 767 individuals infected with S. haematobium, 675 (88.0%) received treatment. Two single oral doses of 40mg/kg praziquantel were given 6 weeks apart. Of the 675 participants, heavy infection intensity was more common in males than females (chi(2)=6.61, P=0.010). Six weeks later, 624 participants (92.4%) were successfully followed up. The overall cure rate was 88.5% and the egg reduction rate was 98.2%. The highest cure rate was among those individuals with light infection. Seventy-two individuals remained infected at 6 weeks post treatment, among which 3 and 69 individuals had heavy and light infection, respectively. Forty-six of these children resolved following a second round of treatment at 6 weeks follow-up. Of the remaining children successfully followed-up, 22 resolved after a third round of treatment 6 months later. A wide range of observed mild and transient side effects were not associated with egg intensity. The parasitological cure rate was not associated with gender or age. Our study demonstrates that praziquantel is efficacious against S. haematobium in Zimbabwe, although low levels of persistent infection warrant further investigation.

Erythrocyte omega-3, omega-6 and trans fatty acids in relation to risk of preeclampsia among women delivering at Harare Maternity Hospital, Zimbabwe.

We sought to examine the association between maternal erythrocyte omega-3, omega-6 and trans fatty acids and risk of preeclampsia. We conducted a case-control study of 170 women with proteinuric, pregnancy-induced hypertension and 185 normotensive pregnant women who delivered at Harare Maternity Hospital, Harare, Zimbabwe. We measured erythrocyte omega-3, omega-6 and trans fatty acid as the percentage of total fatty acids using gas chromatography. After multivariate adjustment for confounding factors, women in the highest quartile group for total omega-3 fatty acids compared with women in the lowest quartile experienced a 14% reduction in risk of preeclampsia (odds ratio 0.86, 95% confidence interval 0.45 to 1.63). For total omega-6 fatty acids the odds ratio was 0.46 (95% confidence interval 0.23 to 0.92), although there was suggestion of a slight increase in risk of preeclampsia associated with high levels of arachidonic acid. Among women in the highest quartile for arachidonic acid the odds ratio was 1.29 (95% confidence interval 0.66 to 2.54). A strong statistically significant positive association of diunsaturated fatty acids with a trans double bond with risk of preeclampsia was observed. Women in the upper quartile of 9-cis 12-trans octadecanoic acid (C(18:2n6ct)) compared with those in the lowest quartile experienced a 3-fold higher risk of preeclampsia (odds ratio = 3.02, 95% confidence interval 1.41 to 6.45). Among women in the highest quartile for 9-trans 12-cis octadecanoic acid (C(18:2n6tc)) the odds ratio was 3.32 (95% confidence interval 1.55 to 7.13). Monounsaturated trans fatty acids were also positively associated with the risk of preeclampsia, although of much reduced magnitude. We observed a strong positive association of trans fatty acids, particularly diunsaturated trans fatty acids, with the risk of preeclampsia. We found little support for the hypothesized inverse association between omega-3 fatty acids and preeclampsia risk in this population. Polyunsaturated fatty acids, particularly omega-3 fatty acids, were comparatively lower in Zimbabwean than among US pregnant women. Given the limited inter-person variation in omega-3 fatty acids among Zimbabwean women, our sample size may be too small to adequately assess the relation in this population.

Maternal plasma VEGF, sVEGF-R1, and PlGF concentrations in preeclamptic and normotensive pregnant Zimbabwean women.

Vascular endothelial growth factor (VEGF), a disulphide-linked homodimeric glycoprotein that is selectively mitogenic for endothelial cells, plays an important role in vasculogenesis and angiogenesis. Preeclampsia, a relatively common complication of pregnancy that is characterized by diffuse endothelial dysfunction possibly secondary to impaired trophoblast invasion of the spiral arteries during implantation, has recently been associated with alterations in maternal serum/plasma concentrations of VEGF, and other related growth factors and their receptors. We examined the relationship of maternal plasma VEGF, sVEGF-R1 and PlGF levels to the risk of preeclampsia among women delivering at Harare Maternity Hospital, Zimbabwe. 131 pregnant women with preeclampsia and 175 controls were included in a case-control study. Maternal plasma concentrations of each biomarker were measured using enzymatic methods. We used logistic regression to calculate odds ratios (OR) and 95 % confidence intervals (CI). Preeclampsia risk was inversely related with quartiles of plasma VEGF (OR: 1.0, 1.0, 0.7, and 0.5, with the lowest quartile as reference; p for trend=0.06). We noted a strong positive association between preeclampsia risk and sVEGF-R1 concentrations (OR: 1.0, 6.5, 9.7, 31.6, with the first quartile as the referent group; p for trend<0.001). After adjusting for confounders, we noted that women with sVEGF-R1 concentrations in the highest quartile (>or=496 pg/ml), as compared with those in the lowest quartile (<62 pg/ml) had a 31.6-fold increased risk of preeclampsia (OR=31.6, 95 % CI 7.7-128.9). There was no clear evidence of a linear relation in risk of preeclampsia with PlGF concentrations. In conclusion, plasma VEGF, sVEGF-R1 and PlGF concentrations (measured at delivery) were altered among Zimbabwean women with preeclampsia as compared with normotensive women. Our results are consistent with some, though not all, previous reports. Prospective studies are needed to: 1) identify modifiable determinants of maternal plasma concentrations VEGF, sVEGF-R1, and PlGF; and 2) evaluate the temporal relationship between observed alterations of these biological markers in preeclamptic pregnancies.

Preterm delivery risk in relation to maternal HIV infection, history of malaria and other infections among urban Zimbabwean women.

OBJECTIVE: To examine preterm delivery risk in relation to maternal HIV infection, malaria history, and other infections among Zimbabwean women. DESIGN: Hospital based, cross sectional study. SETTING: Harare Maternity Hospital, Harare, Zimbabwe. SUBJECTS: A convenient sample of 500 pregnant women. MAIN OUTCOME MEASURE: Preterm delivery. THE STUDY FACTORS: Maternal socio-demographic information, and infectious disease history (during the year before pregnancy). METHOD: Between July 1998 and March 1999 data were collected for a cross sectional study of pregnant women who delivered at the Harare Maternal Hospital. The association of maternal HIV infection, history of malaria, and other infections with preterm delivery were determined using multivariate analysis. RESULTS: Overall, 497 women were studied, 444 (89.3%) delivered at term and 53 women (10.7%) delivered preterm. Women who delivered preterm were less likely to be HIV seropositive compared with others (odds ratio [OR] = 0.75. 95% confidence interval (CI): 0.38 to 21.48). Preterm delivery was associated with having tuberculosis infections in the year prior to the pregnancy (OR = 10.15, 95% CI: 1.15 to 89.87). Other infections associated with preterm delivery were malaria (OR = 2.39, 95% CI: 1.07 to 5.31), chest infections (OR = 2.63, 95% CI: 0.76 to 9.17), and Herpes (shingles) infection (OR = 2.58, 95% CI: 0.56 to 11.85). Overall, a positive history of any of the non-sexually transmitted infections (in aggregate) was associated with a 3.20 fold increase risk for preterm delivery (OR = 3.20. 95% CI: 1.59 to 6.43). Women with a history of infection and who did not use iron supplements during pregnancy, compared with women without such an history and who used iron supplements, experienced the highest risk for preterm delivery (OR = 8.34, 95% CI: 3.30 to 21.07). CONCLUSION: Maternal non-STD infections, (i.e., tuberculosis, malaria, and chest infections) occurring in the year prior to pregnancy were associated with an increased risk of preterm delivery. The association of non-sexually transmitted infections and preterm delivery was particularly strong among women who did not use iron supplements during pregnancy.

Seroprevalence and risk factors of syphilis infection in pregnant women delivering at Harare Maternity Hospital, Zimbabwe.

OBJECTIVE: To evaluate risk factors and outcomes of syphilis during pregnancy. DESIGN: Hospital based, cross sectional study. SETTING: Harare Maternity Hospital, Harare, Zimbabwe. SUBJECTS: A random sample of 2 969 pregnant women. MAIN OUTCOME MEASURES: Syphilis seroprevalence. RESULTS: Of the 2 969 women who provided blood samples, 4.8% were RPR positive. Approximately 2.2% of study subjects were RPR positive and TPHA negative. Notably, 2.5% of the population was RPR and TPHA positive at the time of giving birth. Older women had a higher risk of having positive syphilis status (p = 0.057). Increases in parity and gravidity were significantly associated with increased risk of syphilis infection. Prior stillbirths were associated with an increased risk of syphilis infection (odds ratio [OR], 3.4; 95% CI, 1.61 to 7.37; p = 0.001). Syphilis positive mothers were significantly more likely to give birth to syphilis positive newborns (p < 0.0001). CONCLUSIONS: Our results suggest that there should be more effective antenatal screening and treatment of syphilis in Harare. Syphilis affects many sub-Saharan countries where effective educational outreach, screening, and treatment should take place to prevent the transmission of this venereal disease, especially among reproductive age and pregnant women.

Plasma tumor necrosis factor-alpha soluble receptor p55 (sTNFp55) concentrations in eclamptic, preeclamptic and normotensive pregnant Zimbabwean women.

We sought to examine the relationship between excessive tumor necrosis factor-alpha (TNF-alpha) release (as measured by sTNFp55 plasma concentrations) and risk of eclampsia and preeclampsia, respectively, among sub-Saharan African women delivering at Harare Maternity Hospital, Zimbabwe. In total, 33 pregnant women with eclampsia, 138 women with preeclampsia and 185 normotensive women were included in a case-control study conducted during the period, June 1995 through April 1996. Postpartum plasma sTNFp55 was measured by enzyme linked immunosorbent assay. Women with eclampsia had significantly higher sTNFp55 than normotensive controls (1.87 vs 1.35 ng/ml, P<0.001). Similarly, women with preeclampsia had sTNFp55 concentrations higher than normotensive controls (1.69 vs 1.35 ng/ml, P < 0.001). The odds ratio for eclampsia was 5.00 (adjusted odds ratio (OR) 5.00, 95% confidence interval (CI) 1.20-20.92) among women in the highest quartile of the control sTNFp55 distribution compared with women in the lowest quartile. The corresponding odds ratio and 95% CI for preeclampsia was 2.37 (1.11-5.06). Postpartum plasma sTNFp55 concentrations are increased among Zimbabwean women with eclampsia and preeclampsia as compared with their normotensive counterparts. These findings are consistent with the hypothesized role of cytokines in mediating endothelial dysfunction and the pathogenesis of preeclampsia/eclampsia. Additional work is needed to identify modifiable risk factors for the excessive synthesis and release of TNF-alpha in pregnancy; and to assess whether measurements of sTNFp55 early in pregnancy may be used to identify women likely to benefit from anti-inflammatory therapy.

Plasma homocyst(e)ine concentrations in eclamptic and preeclamptic African women postpartum.

OBJECTIVE: To examine the relationship between plasma homocyst(e)ine and risk of eclampsia and preeclampsia among sub-Saharan African women who delivered at Harare Maternity Hospital in Zimbabwe. METHODS: We ran a hospital-based, case-control study at Harare Maternity Hospital, University of Zimbabwe, Harare, Zimbabwe comprising 33 pregnant women with eclampsia and 138 with preeclampsia. Controls were 185 normotensive pregnant women. Plasma was collected postpartum and homocyst(e)ine levels were measured by high-performance liquid chromatography and electrochemical detection. RESULTS: Women with eclampsia or preeclampsia had significantly higher mean homocyst(e)ine levels than normotensive controls (12.54 or 12.77 micromol/L versus 9.93 micromol/L, respectively, P<.001). The odds ratio (OR) for eclampsia was 6.03 among women in the highest quartile of the control homocyst(e)ine distribution (median 13.9 micromol/L) compared with women in the lowest quartile (median 6.2 micromol/L). The corresponding OR for preeclampsia was 4.57. Nulliparas with elevated homocyst(e)ine had a 12.90 times higher risk of preeclampsia compared with multiparas without elevated homocyst(e)ine. CONCLUSION: Postpartum plasma homocyst(e)ine concentrations are higher among Zimbabwean women with eclampsia and preeclampsia compared with normotensive women.

Primary health care in Zimbabwe: can it survive? An exploration of the political and historical developments affecting the implementation of PHC.

Using a multi-level perspective, this paper examines the structural constraints and conflicting perspectives affecting the implementation of Primary Health Care (PHC) in Zimbabwe. The analysis of these factors and processes is made by viewing the situation from the different perspectives, perceptions and actions of the state, the health workers and the population. It is argued that the continuing structural inequalities, the bureaucratic and centralization tendencies, the historical development and colonial transplantation of biomedical practice, and the de facto lack of support by government, constrain the implementation of PHC.

Cultural and structural influences in the creation of and participation in community health programmes.

Community participation in health care programmes is considered axiomatic in health development. Cultural and structural influences are discussed in relation to community participation with the intention of highlighting some critical issues affecting its generation and sustainability. These influences include structurally defined perspectives and perceptions of community participation, limitations of the necessary supportive systems, the structural and cultural factors of marginalization, community stratification and organization, mobilization, and the political context. It is concluded that given these factors against a situation of a financial and economic crisis, of economic restructuring and the values of competition and individualization, community participation will be increasingly difficult to generate and sustain.

Birthweight and blood pressure among children in Harare, Zimbabwe.

AIM: To determine whether poor uterine growth may be associated with increased blood pressure and subsequent hypertension in adulthood. METHODS: A retrospective cohort study of 756 schoolchildren (mean age 6.5 years) was carried out in six low income areas in Harare city, Zimbabwe. Indices of intrauterine growth and blood pressure were assessed. RESULTS: Adjusted for current weight, the children's systolic blood pressure was inversely related to their birthweight; for each decreasing kg of birthweight, systolic blood pressure rose by 1.73 mm Hg (95% CI; 0.181 to 3.28). After adjustment for current weight, systolic blood pressure was also inversely associated with occipito-frontal circumference, but not with birth length or gestational age. Diastolic blood pressure was not associated with any of the intrauterine indices. CONCLUSION: Fetal size may be inversely related to systolic blood pressure in childhood in an African population.

A pre-intervention survey to determine understanding of HIV and AIDS in farm worker communities in Zimbabwe.

A cumulative total of 41,298 AIDS cases have been reported in Zimbabwe as of March 1995. Of concern is the growing evidence of high levels of seroprevalence among rural farm workers. A pre-intervention survey was conducted by interview in one district to examine behavioral factors likely to place farm workers in marginalized rural communities at risk for sexually transmitted diseases (STD) and HIV infection. Seven hundred seventy commercial farm workers from 17 randomly selected commercial farm participated in the study. We found that farm worker communities, which are characterized by educationally disadvantaged women when compared with men (p < .001), have had little exposure to AIDS prevention activities. Beliefs that AIDS is brought about by divine or ancestral retribution were upheld by less education women (p < .001). A significant association was found with respect to perceived risk to HIV and low self-efficacy among uneducated women who articulated helplessness and an inability to protect themselves from HIV infection. Among more educated men, we found acknowledgment about multipartnering and that changes in behavior are more likely to develop as a result of changes in normative values (p = .075). Condom use among men, which is probably the most effective barrier against STD infection, was shown to be associated with age (p < .01) and education (p < .01). The study concludes with recommendations for an appropriate intervention.

Prospects for tobacco control in Zimbabwe: a historical perspective.

Using a historical and political economy perspective, this paper explores the prospects for tobacco control in Zimbabwe, the world's sixth largest producer and third largest tobacco exporter. Tobacco production, which first began in the former Rhodesia in the early 1900s, is closely associated with colonial history and land occupation by white settlers. The Zimbabwe (formerly Rhodesia) Tobacco Association was formed in 1928 and soon became a powerful political force. Although land redistribution has always been a central issue, it was not adequately addressed after independence in 1980, largely due to the need for Zimbabwe to gain foreign currency and safeguard employment. However, by the mid-1990s political pressures forced the government to confront the mainly white, commercial farmers with a new land acquisition policy, but intense national and international lobbying prevented its implementation. With advent of global economic changes, and following the start of a structural adjustment programme in 1991, manufacturing began to decline and the government relied even more on the earnings from tobacco exports. Thus strengthening tobacco control policies has always had a low national and public health priority. Recent illegal occupation of predominantly white owned farms, under the guise of implementing the former land redistribution policy, was politically motivated as the government faced its first major challenge at the general elections in June 2000. It remains unclear whether this will lead to long term reductions in tobacco production, although future global declines in demand could weaken the tobacco lobby. However, since Zimbabwe is only a minor consumer of tobacco, a unique opportunity does exist to develop controls on domestic cigarette consumption. To achieve this the isolated ministry of health would need considerable support from international agencies, such as the World Health Organisation and World Bank.

Development of a computerized information system in the Harare City Health Department.

The experience is reported with the health information system of the Health Department of Harare City, five years after its introduction. The system was evaluated in terms of the implementation procedure and improvements in the management process. It is concluded that careful management of the implementation process itself is a key to the successful realization of a health information system in developing countries. The statement that the quality of information produced during a computerization process is only as good as the original data fed into it, is emphasized.

Leukocyte selenium, zinc, and copper concentrations in preeclamptic and normotensive pregnant women.

Preeclampsia is an important cause of maternal and perinatal mortality worldwide. The etiology of this relatively common medical complication of pregnancy, however, remains unknown. We studied the relationship between maternal leukocyte selenium, zinc, and copper concentrations and the risk of preeclampsia in a large hospital-based case-control study. One hundred seventy-one women with proteinuric pregnancy-induced hypertension (with or without seizures) comprised the case group. Controls were 184 normotensive pregnant women. Leukocytes were separated from blood samples collected during the patients' postpartum labor and delivery admission. Leukocyte concentrations for the three cations were measured by inductively coupled plasma-mass spectrometry (ICP-MS). Concentrations for each cation were reported as micrograms per gram of total protein. Women with preeclampsia had significantly higher median leukocyte selenium concentrations than normotensive controls (3.23 vs 2.80 microg/g total protein, p < 0.0001). Median leukocyte zinc concentrations were 31% higher in preeclamptics as compared with controls (179.15 vs 136.44 microg/g total protein, p < 0.0001). Although median leukocyte copper concentrations were slightly higher for cases than controls, this difference did not reach statistical significance (17.72 vs 17.00 microg/g total protein, p = 0.468). There was evidence of a linear increase in risk of preeclampsia with increasing concentrations of selenium and zinc. The relative risk for preeclampsia was 3.38 (adjusted odds ratio [OR] = 3.38, 95% confidence interval [CI] = 1.53-7.54) among women in the highest quartile of the control selenium distribution compared with women in the lowest quartile. The corresponding relative risk and 95% CI for preeclampsia was 5.30 (2.45-11.44) for women in the highest quartile of the control zinc distribution compared with women in the lowest quartile. There was no clear pattern of a linear trend in risk with increasing concentration of leukocyte copper concentrations (adjusted for linear trend in risk = 0.299). Our results are consistent with some previous reports. Prospective studies are needed to determine whether observed alterations in selenium and zinc concentrations precede preeclampsia or whether the differences may be attributed to preeclampsia-related alterations in maternal and fetal-placental trace metal metabolism.

Who are the Zimbabwean loop users? The social and demographic characteristics of Zimbabwean IUCD users.

As part of a study into the reasons for the low utilization of the intra-uterine contraceptive device (IUCD) among Zimbabwean women, a records' review of IUCD users over the period 1985 to 1989 was carried out. A 10 pc sample of the records of women inserted over this period was taken. This paper reports on the social demographic and selected screening characteristics of these women. A total of 1,179 records were reviewed. The IUCD users had a higher socio-economic status than the Zimbabwean population as a whole. Nearly 20 pc of the IUCD users were professional, technical and related workers, (mostly nurses and teachers), compared to 4.3 pc among the general population. Clients had apparently better reproductive histories than the population as a whole, probably reflecting their socio-economic status and possibly the screening process. The women were in their mid to late twenties in age at the time of insertion, and had been married an average of nine years. A quarter of the clients did not want any more children. They were using the IUCD to suspend their conception indefinitely after completion of their families. About 74 pc of the women had learnt about the family planning clinic from the local clinic/nurses or the community based distributor, indicating the importance of these sources of information. Eighty pc of the women were previous acceptors of modern contraceptives, but only 6 pc had apparently used the IUCD before.(ABSTRACT TRUNCATED AT 250 WORDS)

Blood pressure tracking from child to adulthood: a review.

This paper reviews blood pressure tracking from childhood through adolescence, to adulthood. Blood pressure tracking correlations in childhood and adolescence vary from 0.2-0.6. Systolic blood pressure tracks better than diastolic pressure. There does not appear to be a gender difference, except that girls mature earlier than boys and so reach their adult blood pressure sooner. Tracking could be improved by increasing the number of observations per time period, thus reducing intrasubject variability. Various models, which do not assume linearity, have been developed to improve prediction. However, more studies with longer follow up periods need to be carried out to assess the importance of tracking as a screening tool. There is need also, for further studies in Africa, as the epidemiology of hypertension appears to be different in this setting. From the available data though, large scale screening programmes for children and adolescents are of little merit at this time.

Predictive factors for medical students and housemen to work in rural health institutions in Zimbabwe.

A survey was conducted among medical students and housemen in order to identify factors associated with the choice of future practice in Zimbabwe. A total of 150 medical students and housemen participated in the study. The medical students and housemen were 6.5 (95 pc CI 1.6-26.6), 4.0 (95 pc CI 1.3-12.8) and 3.2 (95 pc CI 1.1-9.4) more likely to work in an urban than rural area for at least three years because of the prestige in the community, standard of living and salary, respectively. Further studies should be done to test whether raising the prestige in the community, standard of living and salary in rural areas would attract more physicians to work in rural health institutions in Zimbabwe.
