Abstract
BACKGROUND The risk factors of Noncommunicable diseases (NCDs) are not routinely monitored, especially among populace reporting to hospitals to detect and also advise on preventive measures, a key strategy to reducing the impact of NCDs on the Health Care System and population. METHODS A cross-sectional survey was carried out between the months of May and June, 2010 among a sample representative of the medical and surgical out-patients population to determine the prevalence of certain risk factors of non-communicable diseases (NCDs). Participants (n = 230) were selected by systematic random sampling. Standardised international protocols were used to measure the prevalence of smoking, alcohol consumption, physical inactivity, obesity, raised blood pressure, raised blood glucose and total cholesterol. RESULTS The obesity level of the study population was 40.4% with 54% being overweight. Tobacco use among the respondents was 4.8%. Alcohol consumption was 64.8%, with 54.3% of the study population being physically inactive. Almost 48%and 70.9% of the participants consumed fruits and vegetables respectively, at least three days in a week. The prevalence of hypertension was 33.6% for men and 35.2% for women. The prevalence of raised glucose and total blood cholesterol level among the study population was 6.5%. Almost 62% of the participants had a combination of three or more risk factors. CONCLUSION The prevalence of the significant risk factors in this study were physical inactivity (54.3%), alcohol consumption (64.8%), overweight (54%), obesity (40.4%) and raised blood pressure (34.3%). Hospitals should therefore include NCD risk factor monitoring as part of routine services.

Abstract
OBJECTIVE This study investigated the prevalence and incidence of Traditional (where a person in a position of power harasses a subordinate) and contra power sexual harassment, (where a subordinate is the harasser of authority figure) in medical schools in Ghana. among. DESIGN Cross-sectional study. METHOD Four hundred and nine medical students from four medical schools in Ghana were interviewed. We also considered if academic and financial dependence would predict either traditional or contra power sexual harassment. We further investigated, whether women were more bothered by sexual harassment than men and the correlation between sexual harassment and health. RESULTS Women were 61% more likely to be sexually harassed than men 39%. Sexual harassment negatively affects the victims' health outcome. We found that the traditional form of sexual harassment was prevalent in medical schools in Ghana and that academic dependence predicted attacks. In the first and second years, women at these institutions are more likely to be sexually harassed than men. CONCLUSION Sexual harassment policies of medical school need to be widely circulated. The various medical schools should provide reporting procedures and counseling for victims. This paper would inform policy and research.

Abstract
OBJECTIVE This paper assessed the emergency preparedness programs of health facilities for all-risks but focused on Road Traffic Accidents, (RTA) resulting in surge demand. It adopted W. H. O checklist covering hospital preparedness, equipment, manpower and surge capacity planning as best practices for the mitigation of public health emergencies. METHOD This is a cross-sectional study of purposively selected health facilities. The method used consisted of site visit, questionnaire survey, literature and internet review. The W. H. O. standard for emergency preparedness of health facilities was used to evaluate and assess the nation's hospitals surge capacity programs. The study was conducted between March-June, 2010. A total of 22 district and regional health facilities including teaching hospitals participated in the study. All 10 regions of the country were covered. RESULT These were: (1) many of the nation's hospitals were not prepared for large RTA's resulting in surge demands, and did not possess general emergency preparedness programs. (2) The hospitals' respective abilities to handle large scale RTA's were compromised by the lack of competent medical and allied health personnel and adequate supplies. DISCUSSION The inadequacies of the hospital system in responding to emergencies raise serious public health concerns. The biggest challenge facing the hospitals in their emergency intervention is the lack of pre-emergency and emergency preparedness plans as well as the coordination of the hospitals response mechanisms. CONCLUSION The paper ended with recommendations on how the nation's hospitals and their supervisory agencies could improve emergency preparedness.

Abstract
Hospitals and other health facilities in Ghana do not appear to have standardized practices for quarantine and isolation in public health emergency management. This paper reviews the legislative framework governing the medico-legal prerequisites for initiating quarantine and isolation procedures as articulated in the Infectious Disease Act (Cap 78) 1908 amended, 1935, the Quarantine Act (Cap 77) 1915 amended, 1938, the Emergency Powers Act of 1994, (Act 472), and the National Disaster Management Act, 1996, (Act 517) in consonance with the 1992 Constitution of Ghana. The findings provide that (1) The legislative framework outlines systematic standards and protocols to be followed in the committal of person or persons in quarantine and isolation during public health emergencies. (2) These standards and protocols consider as imperative, the creation of standardized national templates for the initiation of quarantine and isolation measures. (3) The non-compliance of the standards and protocols renders vulnerable medical facilities and hospitals with their personnel to the threat of medical malpractice suits and breach of professional ethics. This paper provides suggestions to hospital administrators and medical personnel of how to develop administrative templates in compliance with the law in managing public health emergencies. It also provides examples of such templates for possible adoption by hospitals and other health administrators.

Abstract
OBJECTIVES The National Health Insurance Scheme (NHIS), and the National Identification Authority (NIA), pose ethical challenges to the physician-patient relationship due to interoperability. This paper explores (1) the national legislation on Electronic Health Information Technology (EHIT), (2) the ethics of information technology and public health and (3) the effect on the Physician-patient relationship. METHOD This study consisted of systematic literature and internet review of the legislation, information technology, the national health insurance program, and the physician-patient relationship. RESULT The result shows that (1) EHIT have eroded a big part of the confidentiality between the physician and patient; (2) The encroachment on privacy is an inevitable outcome of EHIT; (3) Legislation on privacy, the collection, storage and uses of electronic health information is needed and; (4) the nexus between EHIT, NHIS, NHA, Ethics, the physician-patient relationship and privacy. CONCLUSION The study highlights the lack of protection for physician-patient relationship as medical practice transitions from the conventional to the modern, information technology driven domain.

Abstract
OBJECTIVE The study was conducted to determine antimalarial prescribing practices among prescribers in 2 of the 6 sentinel sites established to document antimalarial drug efficacy in Ghana in order to provide some explanation underlying chloroquine treatment failures in the country. SUBJECTS AND METHODS The study was descriptive combining both qualitative and quantitative designs. The qualitative design involved in-depth interviews of general prescribers in the Wassa West and Kassena Nankana districts using an interview guide. The quantitative design involved a review of Outpatient Department prescriptions of 100 patients clinically diagnosed as having malaria within the year 2000 in each of the 7 selected health care facilities. RESULTS The overall number of drugs prescribed per patient encounter was 4.3 in the Wassa West district and 3.0 in the Kassena Nankana district. The number of drugs per patient encounter was 5.4 and 3.7 in private and government health care facilities, respectively. The commonly prescribed antimalarial drug in all the health care facilities visited was chloroquine. However, only 9.8% of prescriptions in private health care facilities contained correct doses of chloroquine compared to 54% in government health care facilities (p = 0.000). Prescriptions containing chloroquine injections were least likely to have correct doses of chloroquine. CONCLUSION The findings indicate that although chloroquine remained the first-line drug in the treatment of uncomplicated malaria in the two districts, the level of appropriateness of doses prescribed was generally low. Inappropriate doses of chloroquine prescribed were more prevalent in private than government health care facilities, and among prescriptions containing injections.

Abstract
A 17% efficacy in preventing all-cause mortality in children aged 6-59 months was previously reported from a cluster-randomized controlled trial of insecticide-treated mosquito nets (ITNs) carried out in the Kassena-Nankana District of northern Ghana from July 1993-June 1995. A follow-up until the end of 2000 found no indication in any age group of increased mortality in the ITN group after the end of the randomized intervention. These results should further encourage the use of ITNs as a malaria control tool in areas of high endemicity of Plasmodium falciparum.

Abstract
Accurate data are always needed to inform health policy, but are especially critical in tackling health inequities. The growing number of field research stations in sub-Saharan Africa are well-placed to generate relevant data and so support health policy action. Over the past 60 years, demographic surveillance systems have been crucial research tools for the evaluation of health interventions aimed at reducing socioeconomic differentials in mortality and morbidity in sub-Saharan Africa. The bulk of such work has been carried out by field research sites, often operating in remote, resource-constrained settings. The present paper reviews what we have learned since the pioneering work carried out in the field sites of Pholela (South Africa) and Niakhar (Senegal). It then focuses on current efforts to address health equity through INDEPTH, the international network of field sites with continuous demographic evaluation of population and their health in developing countries.

Abstract
The impact of insecticide-treated bednet use on malaria and anaemia in pregnancy was assessed, as a supplementary study, in a major WHO/TDR-supported bednet trial in northern Ghana between July 1994 and April 1995. The study area was divided into 96 clusters of compounds, with 48 clusters being randomly allocated to intervention. All pregnant women were included in the study but the focus was on primigravidae and secundigravidae. 1961 pregnant women were recruited into the study--1033 (52.7%) in the treated bednet group and 928 (47.3%) in the no net group. 1806 (92.1%) had blood taken for malaria microscopy and haemoglobin determination in the third trimester. Pregnancy outcomes were reported for 847 women. The characteristics of women in intervention and control groups were comparable. The odds ratios, with 95% confidence interval (CI), for different study endpoints were, for Plasmodium falciparum parasitaemia--0.89 (0.73, 1.08), for anaemia--0.88 (0.70, 1.09), for low birthweight (LBW)--0.87 (0.63, 1.19), indicating no benefit for treated bednet use. Effective net use by parity varied from 42% in primigravidae to 63% in multigravidae, in spite of free nets and insecticide impregnation. The main reasons for not using a net were warm weather and perceived absence of mosquito biting. Chloroquine use in pregnancy was low and comparable in both groups. Implications of findings for malaria control in pregnancy and further research are discussed.

Abstract
Adult residents of holoendemic malaria regions in Africa have a naturally acquired immunity (NAI) to malaria that renders them more resistant to new infections, limits parasitemia, and reduces the frequency and severity of illness. Given such attributes, it is not clear how one might evaluate drug or vaccine efficacy in adults without serious confounding. To determine symptomatic and asymptomatic malaria attack rates in adults of northern Ghana, 197 men and women underwent curative therapy for any pre-existing malaria infections at the start of the high transmission (wet) season. They were monitored for first parasitemia and first clinical episode of infection by Plasmodium falciparum over a 20-week period (May-October 1996). The cumulative incidence of primary infection by P. falciparum was 0.98 and incidence density of infection was calculated to be 7.0 cases/person-year. Symptoms were reported by 19.5% of the individuals at the time of first recurrent parasitemia. Incidence of infection, parasite density, and the frequency of symptoms were comparable in males and females. The results suggest that NAI did not provide these adults with significant defense against rapid re-infection and suggest that this population-infection design could serve to demonstrate the efficacy of a drug or vaccine in preventing parasitemia.

Abstract
An epidemiological study of rotavirus infection was conducted on specimens collected from patients with gastroenteritis and domiciled in the rural Upper Eastern Region of Ghana during 1998. Fifty isolates, randomly selected from 165 human group A rotavirus-positive samples, were G and P characterized by a reverse transcription (RT)-PCR assay using a seminested multiplex method. Rotaviruses of the G3 genotype were found to be the predominant strain (78%), followed by G2 (14%) and G1 (2%). Mixed infections, as shown by combinations of G3 and G2 (4%) and G3 and G1 (2%), were also observed. P typing showed P[4] (72.34%) to be the prevalent strain, followed by P[6] (21.3%), P[8] (2.13%), and a combination of P[4] and P[6] (4.3%).

Abstract
Malaria and anemia accounted for 41% and 18% respectively of hospital deaths in the Kassena-Nankana district of northern Ghana during 1996. We measured hemoglobin (Hb), malaria prevalence, and anthropometric indices of 6--24-month-old infants and young children randomly selected from this community at the end of the high (May-October, n = 347) and low (November-April, n = 286) malaria transmission seasons. High transmission season is characterized by rainfall (the equivalent of 800-900 mm/yr.), while the remaining months receive less than 50 mm/yr. Severe anemia, defined as Hb < 6.0 g/dL, was 22.1% at the end of the high transmission season compared to 1.4% at the end of the low transmission season (Odds Ratio [OR] = 20.1; 95% CI: 7.1-55.3). Parasitemia was 71% and 54.3% at these time points (OR = 2.1; 95% CI: 1.5-2.9). Nutritional anemia appeared to have little impact upon this seasonal difference since anthropometric indices were comparable. Although the relative contributions of other causes of severe anemia were not assessed, repeated malaria infections may be a primary determinant of severe anemia among infants and young children during the high transmission season.

Abstract
Effects of the distribution in space of permethrin (insecticide)-impregnated bed nets (IIBNS) on child mortality were studied in a randomized controlled trial of IIBNs in a an area highly endemic for Plasmodium falciparum malaria in rural northern Ghana. Eight hundred sixty-two deaths occurred among children 6-59 months of age during 16,841 child-years-at-risk. Mortality increased with the distance from health facilities but not with proximity to identifiable anopheline breeding sites (reservoirs). The efficacy of IIBNs was independent of these distances. Mortality in users of IIBNs was independent of the proximity of nonusers, and mortality rates of nonusers and users living close to each other were similar. Poisson regression estimated a 6.7% increase in mortality among nonusers with each 100-m shift away from the nearest compound with IIBNS, indicating that the insecticide protects nearby nonusers. High coverage of IIBNs achieves maximum impact, but users of IIBNs offer some protection to less fortunate neighbors if coverage is incomplete.

Abstract
This article presents findings from a study of the influence of traditional religion on reproductive preferences of Kassena-Nankana lineage heads in northern Ghana. Seven reproductive preference questions were administered to nine lineage heads who are primary practitioners of the cult of soothsaying. With the assistance of soothsayers, interviews were repeated in conjunction with the invocation of religious rites in order to determine the views of ancestral spirits on the seven questions. Pairs of lineage head and ancestral interviews are compared to determine the role of traditional religion in shaping male reproductive preferences. Interview pairs reflect a shared preference for sons, large compounds, and a growing lineage. Findings nonetheless show that some ancestral spirits want small families, some even wanting fewer children than corresponding lineage heads. Spiritual consultations are nondogmatic and open to external ideas and influences, suggesting that family planning introduction will not encounter systematic religious opposition among the Kassena-Nankana.

Abstract
This study presents a focus group investigation of reasons why women in a rural, Sahelian community are reluctant to adopt family planning even when convenient services are made freely available. First, women opting to practice contraception must do so at considerable risk of social ostracism or familial conflict. Implementing individual preference is something that must be done without the support of others. Second, few women view personal decisions about contraceptives as theirs to make. Women and children are the property of the corporate family-kin and community militate against reproductive control. Third, although children are highly valued for a variety of economic, social, and cultural reasons, mortality risks remain extremely high. Low fertility imposes the unacceptable risk that a woman will have no surviving children at the end of her reproductive life. Taken together, these findings attest to the inadequacy of service strategies focused on the contribution of distribution, individual agency, or personal choice. Outreach should also build a sense of community legitimacy for the program, collective health action, and traditional leadership support for family planning behavior.

Abstract
Data on measles incidence, acute case fatality, and delayed mortality were collected on 25,443 children aged 0-95 months during the course of a community-based, double-blind, placebo-controlled, randomized trial of vitamin A supplementation in rural, northern Ghana between 1989 and 1991. Measles vaccine coverage in these children was 48%. The overall estimated measles incidence rate was 24.3 per 1,000 child-years, and acute case fatality was 15.7%. There was not significantly increased mortality in survivors of the acute phase of measles compared with controls (rate ratio = 1.22, 95% confidence interval (CI) 0.65-2.30). Reported incidence rates and case fatality were higher in families with low paternal education, in the dry season, and in unvaccinated children, and case fatality was higher in malnourished children. There was no sex difference in incidence, but acute case fatality was somewhat higher in girls than boys (adjusted odds ratio = 1.3, 95% CI 0.9-2.1). Measles incidence was lower in vitamin A-supplemented groups (23.6 per 1,000 child-years) than in placebo groups (28.9 per 1,000 child-years), but this difference was not statistically significant (p = 0.33). Among 946 measles cases in clusters randomized to receive vitamin A or placebo, there was no marked difference in acute measles case fatality between vitamin A-supplemented and placebo groups (15.4% vs. 14.5%, respectively). The biologic effects of vitamin A supplemented on the subsequent clinical manifestations and severity of measles need further elucidation.

Abstract
Permethrin impregnated bednets are now being widely promoted as an effective means of protecting African children against malaria, but there is little evidence of their cost-effectiveness. The impact on child mortality of introducing permethrin impregnated bednets was evaluated in a rural district of northern Ghana in a controlled trial. The cost-effectiveness of the intervention is reported in this paper. The total cost of the intervention over the 2 years of follow-up was US $148,245. Cost per impregnated bednet per year and per person protected per year was US $2.4 and 1.2, respectively. Approximately 16,800 child years were protected and 74 child deaths averted at an estimated cost of US $8.8 per child year protected and US $2003 per death averted. In this rural community, where life expectancy at the mean age of death of trial children was 57.5 years, the estimated cost per discounted healthy life-year gained was US $73.5. Sensitivity analysis suggested that this cost-effectiveness ratio might be reduced substantially by feasible changes in programme implementation. This study supports the argument that the cost-effectiveness of bednet impregnation is sufficiently attractive to make it part of a package of high priority interventions for children. Issues of how to finance the provision of nets and insecticide, and especially the relative contribution of governments, households and donors, need urgently to be addressed.

Abstract
A district-wide study was undertaken in a rural population of northern Ghana to identify factors influencing the acceptance and use of insecticide-impregnated bednets (IIBNs). A series of focus group discussions were conducted during 2 years of implementation of IIBNs to gauge community reactions to the introduction of the nets and a structured questionnaire was administered to approximately 2000 randomly selected individuals. Although the IIBNs were accepted and used because they provided protection from mosquito bites, seasonal factors, patterns of use, and questions of cost were key factors likely to influence the dissemination and effectiveness of bednets. Use of the bednets was highly seasonal. Almost all recipients used their IIBNs in the rainy season (99%), corresponding to the period of high mosquito density and 20% used them in the dry seasons, the period of low mosquito density. Mothers with young children were more likely to wash the bednets frequently (because the children soiled the bednets with faeces and urine), resulting in no protection from the insecticide. Provision of wider bednets, or the provision of plastic sheets with the bednets or possible incorporation of the insecticide in washing soaps could improve protection for young children. The success of the promotion of IIBNs in malaria control programmes will depend on the cost of the package and the time of year that it is delivered. Financing mechanisms for individual and village groups are discussed. Social research effectively monitored the intervention in this study, and it should be included as an important component of national malaria control programmes.

Abstract
In the Upper East Region of Ghana, considerable resources have been invested in the provision of boreholes. As part of the Ghana Vitamin A Supplementation Trials' Survival Study which was carried out in one of the districts of the Upper East Region between January 1989 and December 1991, data were collected over a period of one calendar year on the drinking water sources used by approximately 13,000 mothers/guardians of over 20,000 children and on the morbidity and mortality experiences of these children. These data were used to describe seasonal and geographical variations in drinking water sources; to look for other predictors of water source use; and to establish whether the drinking water source was associated with the risk of child death or the period prevalence of diarrhoea among young children. Boreholes were used as the main source of drinking water by about 60-70% of respondents. They were used slightly more frequently in the dry season. In the rainy season, the use increased of more traditional sources such as rainwater or holes dug in stream beds. The use of boreholes was greatest in the northern zone of the study area and was more common in those who had had some formal education and were of higher socioeconomic status. Some association was found between reported drinking water source and diarrhoeal morbidity, although this association appeared to be seasonal. No significant association was found between drinking water source and child mortality.

Abstract
The effect of prophylactic vitamin A supplementation on child growth was studies in two randomized, placebo-controlled trials carried out in adjacent areas of northern Ghana between 1989 and 1991. In the Health Study, the midupper arm circumference (MUAC) and weight of the approximately 1500 children (aged 6-59 mo) in the trial were measured every 4 wk for up to 52 wk. In addition, MUAC, weight, and height were measured at each of the four potential vitamin A or placebo dosing times, which were at 4-mo intervals. In the Survival Study, MUAC and weight were measured at 4-mo intervals at each of seven dosing rounds in the approximately 15 000 children currently in the trial. Overall, there were > 90 000 observations of weight and MUAC in > 25 000 children, and 3347 observations of length/height in 1546 children. Within each study, the mean monthly weight, MUAC, and gains in length/height in each treatment group were compared by using multilevel modeling. There were no significant differences in either MUAC or gains in length/height. The only significant difference in weight gain was in the Survival Study: children in the vitamin A-supplemented group who were > or = 36 mo of age had a mean weight gain that was 3 g lower per month (95% CI: 0.4, 5.0, P = 0.02) than that in the placebo group; a difference that was unlikely to be functionally important in this age group. Vitamin A supplementation did not lead to any increased growth in this population of young children, in whom supplementation reduced mortality and severe morbidity substantially.

Abstract
A community-based randomized, controlled trial of permethrin impregnated bednets was carried out in a rural area of northern Ghana, between July 1993 and June 1995, to assess the impact on the mortality of young children in an area of intense transmission of malaria and no tradition of bednet use. The district around Navrongo was divided into 96 geographical areas and in 48 randomly selected areas households were provided with permethrin impregnated bednets which were re-impregnated every 6 months. A longitudinal demographic surveillance system was used to record births, deaths and migrations, to evaluate compliance and to measure child mortality. The use of permethrin impregnated bednets was associated with 17% reduction in all-cause mortality in children aged 6 months to 4 years (RR = 0.83; 95% CI 0.69-1.00; P = 0.05). The reduction in mortality was confined to children aged 2 years of younger, and was greater in July-December, during the wet season and immediately after (RR = 0.79; 95% CI 0.63-1.00), a period when malaria mortality is likely to be increased, than in the dry season (RR = 0.92, 95% CI 0.73-1.14). The ready acceptance of bednets, the high level of compliance in their use and the subsequent impact on all-cause mortality in this study has important implications for programmes to control malaria in sub-Saharan Africa.

Abstract
This article describes the first six months of the strategic planning process to develop a culturally appropriate community health and family planning program for a traditional community in a district of northern Ghana, served by the Navrongo Health Research Centre. To explain the context within which fertility decisions are made, this article describes the district's severe ecological, social, economic, and health constraints to family planning. It discusses related programmatic obstacles and presents the strategies developed to respond to them. A system of care has been developed that is closely coordinated with traditional leaders and communication networks. Management systems support outreach workers by emphasizing the importance of peer leadership, supervisory support, and community liaison in the implementation of village-based services. A large-scale experiment will be fielded to test the demographic impact of this approach.

Abstract
Within a large scale community trial in northern Ghana lay interviewers were trained to inquire about and identify elephantiasis of the leg by the use of local terms and simple examination of respondents. This was repeated a year later after moving the interviewers to different geographical areas. The proportions of extended family compounds reported to have at least one member with elephantiasis of the leg were 12.2% and 12.1 % respectively in the first and second surveys (kappa = 0.60). 'Blind' re-examination of a sub-sample by a physician showed a high level of agreement with the lay interviewer's findings in the first and second surveys (kappa = 0.67 and 0.82 respectively). This study has shown that lay people, even with minimal training, can obtain repeatable and valid estimates of the prevalence of elephantiasis of the leg, at least within an area where local terms for the condition are available. This method could potentially be used for other diseases with visible manifestations.

Abstract
OBJECTIVES The impact of large-dose vitamin A supplementation given at intervals of 4 months on child mortality and morbidity was examined according to the time interval since dosing, number of doses received previously, and time of year. METHODS Two double-blind, randomized, placebo-controlled trials of large doses of vitamin A administered at intervals of 4 months were conducted in adjacent populations in northern Ghana. RESULTS While vitamin A supplementation significantly reduced the overall incidence of severe illnesses (especially diarrhea with dehydration), clinic attendances, hospital admissions, and mortality, there was no evidence that the impact of each dose of vitamin A was related to the number of doses the child had received previously. There was no evidence that the effectiveness of the supplement waned over the 3 to 5 months between doses. The impact on mortality did not differ significantly by the month in which the supplement had been given. CONCLUSIONS In the study population, there was no evidence that an interval between doses of less than 4 months would have had a greater impact on severe morbidity or mortality, and the effectiveness of supplementation did not vary by time of year.

Abstract
In 1994, an experiment was launched by the Navrongo Health Research Centre that will test the demographic impact of community health and family planning services in a rural, traditional area of northern Ghana. While exhaustive social research has been directed to clarifying societal constraints to reproductive change, relatively little is known about how African cultural characteristics can be a resource to family planning programs. This study will clarify ways in which cultural resources of a traditional African society can be used in efforts to foster reproductive change. This article reviews characteristics of the study population, the design of the Navrongo experiment, and the research plan. The Navrongo Project will be the first African experimental trial of the demographic impact of family planning.

Abstract
Two companion, randomized, placebo-controlled trials of prophylactic vitamin A supplementation provided the opportunity to assess the impact of supplementation on malaria parasitemia, morbidity, and mortality in young children in northern Ghana. In the mortality study, 21,906 children were visited every 4 mo over 2 y, and in the morbidity study 1455 children were visited weekly for 1 y. There was no difference between children supplemented with vitamin A and those given placebo in malaria mortality rates (rate ratio = 1.03; 95% CI 0.74, 1.43) or fever incidence based on reported symptoms. Malaria parasitemia rates, parasite densities in children with a positive blood smear, and rates of probable malaria illness also did not differ between treatment groups. There was no correlation between serum retinol at the beginning of the trial and subsequent malaria parasitemia in children who received placebo (r = 0.01). It is concluded that vitamin A supplementation had no impact on malaria in this population.

Abstract
BACKGROUND A population-based case-control study was carried out to investigate potential risk factors for post-neonatal and child mortality in northern Ghana were child survival rates are among the lowest in Africa. METHOD Cases were post-neonatal infant and child deaths identified within a large population under continuous demographic surveillance. For each case, one living control, matched for age, sex and locality, was selected from the demographic database. Mothers of each case and control were interviewed to obtain information on social, enconomic, demographic, environmental and other possible risk factors. Matched analyses of the 317 cases and their controls were performed using discordant pairs analysis and conditional logistic regression. RESULTS The mortality rate for children aged 6 months to 4 years was estimated as 23.9/1000 children/year. An increased risk of death was observed where the delivery was not performed by a trained person (OR = 1.8, 95% CI: 1.0-3.2), if the preceding birth interval was < 24 months (OR = 2.2, 95% CI: 1.1-3.9), if the father beat the child's mother (OR = 4.3, 95% CI: 1.2-15.6) or if the water source was unprotected (OR = 1.6, 95% CI: 1.0-2.7). No association was found between weaning practices, parental education, or any of the socioeconomic or hygiene variables considered. CONCLUSIONS Few strong risk factors for mortality were identified, perhaps because living conditions within the study population are relatively homogeneous. While mortality rates may be reduced by targeted interventions, such as increasing deliveries by trained people, more general improvements in the socioeconomic status in the region are essential.

Abstract
A survey of the prevalence of bancroftian filariasis was conducted in August-September 1992 in the northern part of the Kassena-Nankana District, Upper East Region, Ghana. 200 compounds from 3 different communities were randomly selected from the vitamin A trial database. All resident compound members were examined for clinical manifestations of lymphatic filariasis and capillary blood was obtained between 21:00 and 01:00 and examined using the counting chamber technique. 1603 people were examined, 741 males and 862 females. The overall prevalence of microfilaraemia was 32.4% (95% confidence interval 30.1-34.7). Geometric mean microfilaria density (infected persons only) was 794 per mL. The most important clinical manifestation was hydrocele (in 32% of males) followed by limb elephantiasis (in 3.6% of the study population). There was no significant difference between the 3 communities in clinical or parasitological findings.

Abstract
A malaria prevalence survey was carried out in young children in northern Ghana between October 1990 and September 1991, in an area with continuous mortality and morbidity surveillance. There was marked seasonal variation in malaria deaths, reported fevers, parasite rates and mean parasite densities, with parasite rates reaching 85-94% in the wet season. The monthly numbers of malaria deaths were highly correlated with rainfall in the previous 2 months (r = 0.90, P < 0.001). Parasite rates were highest in the oldest children (5-7 years), but parasite densities and rates of febrile illness were highest in those 6-11 months old. Haemoglobin levels were also at their lowest in this age group. The predominant species, Plasmodium falciparum, was present in 71% of all blood films. Febrile illness was well recognized by mothers, but it was not possible to construct a simple clinical diagnostic algorithm which would identify even 50% of children with high levels of malaria parasitaemia (> or = 4000 parasites/microL). Malariometric indicators appear to have changed little in this area since a previous survey in 1955.

Abstract
BACKGROUND Methodological issues in the design and interpretation of cross-sectional interview surveys of the prevalence of acute respiratory infections (ARI) were assessed among young children. METHODS A cross-sectional survey was conducted in approximately 20,000 children in the north of Ghana. Approximately half were administered a questionnaire in which the initial questions about recent illnesses were direct questions about the presence or absence of three specific ARI-related symptoms (cough, rapid breathing, difficulty breathing), while the other half were administered a questionnaire which started with an open-ended question on whether the child was ill, designed to elicit spontaneous responses. A 2-week recall period was used in addition to point prevalence questions for half of the children in each group, while 4 weeks was used for the other half. The results were compared with those from a longitudinal morbidity surveillance system in an adjacent population of children. The repeatability of the responses to each of the symptoms/conditions was assessed in a subsample of the children. RESULTS AND CONCLUSIONS The point and period prevalence rates of ARI symptoms or conditions based on spontaneously elicited responses were more likely to be valid than those based on prompted responses. Furthermore, using a 2-week recall period appeared to give more valid period prevalence rates than a 4-week recall period. The repeatability of the various ARI questions was not high (kappas 0.14 to 0.49), irrespective of the questionnaire design. Whether these findings will also be true in other populations needs to be assessed.

Abstract
A survey was carried out over 1 year in a rural area of Ghana on the isolation, detection and/or identification of enteric pathogens from children under 5 years of age with and without diarrhoea. The isolation and detection rate of Shigella flexneri, Shigella dysenteriae, Giardia lamblia and Rotavirus were higher in children with diarrhoea than in controls. Yersinia enterocolitica, Vibrio cholerae and Vibrio parahaemolyticus were not isolated during the period of this survey. The incidence of other enteropathogenic bacteria and parasites identified in the diarrhoeal and non-diarrhoeal children was calculated and is discussed in this study.
