RESUMEN

CONTEXT: Globally, 1 in 3 children under 5 years is undernourished or overweight, and 1 in 2 suffers from hidden hunger due to nutrient deficiencies. As children spend a considerable time at school, school-based policies that aim to improve children's dietary intake may help address this double burden of malnutrition. OBJECTIVE: This systematic review aimed to assess the effects of implementing policies or interventions that influence the school food environment on children's health and nonhealth outcomes. DATA SOURCES, EXTRACTION, AND ANALYSIS: Eleven databases were searched up to April 2020 and the World Health Organization (WHO) released a call for data due in June 2020. Records were screened against the eligibility criteria, and data extraction and risk-of-bias assessment were conducted by 1 reviewer and checked by another. The synthesis was based on effect direction, and certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. CONCLUSIONS: Seventy-four studies reporting 10 different comparisons were included. The body of evidence indicates that interventions addressing the school food environment may have modest beneficial effects on certain key outcomes. Nutrition standards for healthy foods and beverages at schools, interventions that change how food is presented and positioned, and fruit and vegetable provision may have a beneficial effect on the consumption of healthy foods and beverages. Regarding effects on the consumption of discretionary foods and beverages, nutrition standards may have beneficial effects. Nutrition standards for foods and beverages, changes to portion size served, and the implementation of multiple nudging strategies may have beneficial effects on energy intake. Regarding effects of purchasing or selecting healthier foods, changes to how food is presented and positioned may be beneficial. This review was commissioned and supported by the WHO (registration 2020/1001698-0). WHO reviewed and approved the protocol for the systematic review and reviewed the initial report of the completed systematic review. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no: CRD42020186265.

RESUMEN

An evidence-based approach is considered the gold standard for health decision-making. Sometimes, a guideline panel might judge the certainty that the desirable effects of an intervention clearly outweigh its undesirable effects as high, but the body of supportive evidence is indirect. In such cases, the application of the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach for grading the strength of recommendations is inappropriate. Instead, the GRADE Working Group has recommended developing ungraded best or good practice statement (GPS) and developed guidance under which circumsances they would be appropriate.Through an evaluation of COVID-1- related recommendations on the eCOVID Recommendation Map (COVID-19.recmap.org), we found that recommendations qualifying a GPS were widespread. However, guideline developers failed to label them as GPS or transparently report justifications for their development. We identified ways to improve and facilitate the operationalisation and implementation of the GRADE guidance for GPS.Herein, we propose a structured process for the development of GPSs that includes applying a sequential order for the GRADE guidance for developing GPS. This operationalisation considers relevant evidence-to-decision criteria when assessing the net consequences of implementing the statement, and reporting information supporting judgments for each criterion. We also propose a standardised table to facilitate the identification of GPS and reporting of their development. This operationalised guidance, if endorsed by guideline developers, may palliate some of the shortcomings identified. Our proposal may also inform future updates of the GRADE guidance for GPS.

RESUMEN

OBJECTIVES: To evaluate the development and quality of actionable statements that qualify as good practice statements (GPS) reported in COVID-19 guidelines. DESIGN AND SETTING: Systematic review . We searched MEDLINE, MedSci, China National Knowledge Infrastructure (CNKI), databases of Grading of Recommendations Assessment, Development and Evaluation (GRADE) Guidelines, NICE, WHO and Guidelines International Network (GIN) from March 2020 to September 2021. We included original or adapted recommendations addressing any COVID-19 topic. MAIN OUTCOME MEASURES: We used GRADE Working Group criteria for assessing the appropriateness of issuing a GPS: (1) clear and actionable; (2) rationale necessitating the message for healthcare practice; (3) practicality of systematically searching for evidence; (4) likely net positive consequences from implementing the GPS and (5) clear link to the indirect evidence. We assessed guideline quality using the Appraisal of Guidelines for Research and Evaluation II tool. RESULTS: 253 guidelines from 44 professional societies issued 3726 actionable statements. We classified 2375 (64%) as GPS; of which 27 (1%) were labelled as GPS by guideline developers. 5 (19%) were labelled as GPS by their authors but did not meet GPS criteria. Of the 2375 GPS, 85% were clear and actionable; 59% provided a rationale necessitating the message for healthcare practice, 24% reported the net positive consequences from implementing the GPS. Systematic collection of evidence was deemed impractical for 13% of the GPS, and 39% explained the chain of indirect evidence supporting GPS development. 173/2375 (7.3%) statements explicitly satisfied all five criteria. The guidelines' overall quality was poor regardless of the appropriateness of GPS development and labelling. CONCLUSIONS: Statements that qualify as GPS are common in COVID-19 guidelines but are characterised by unclear designation and development processes, and methodological weaknesses.

RESUMEN

INTRODUCTION: To achieve significant progress in global HIV prevention from 2020 onward, it is essential to ensure that appropriate programmes are being delivered with high quality and sufficient intensity and scale and then taken up by the people who most need and want them in order to have both individual and public health impact. Yet, currently, there is no standard way of assessing this. Available HIV prevention indicators do not provide a logical set of measures that combine to show reduction in HIV incidence and allow for comparison of success (or failure) of HIV prevention programmes and for monitoring progress in meeting global targets. To redress this, attention increasingly has turned to the prospects of devising an HIV prevention cascade, similar to the now-standard HIV treatment cascade; but this has proven to be a controversial enterprise, chiefly due to the complexity of primary prevention. DISCUSSION: We address a number of core issues attendant with devising prevention cascades, including: determining the population of interest and accounting for the variability and fluidity of HIV-related risk within it; the fact that there are multiple HIV prevention methods, and many people are exposed to a package of them, rather than a single method; and choosing the final step (outcome) in the cascade. We propose two unifying models of prevention cascades-one more appropriate for programme managers and monitors and the other for researchers and programme developers-and note their relationship. We also provide some considerations related to cascade data quality and improvement. CONCLUSIONS: The HIV prevention field has been grappling for years with the idea of developing a standardised way to regularly assess progress and to monitor and improve programmes accordingly. The cascade provides the potential to do this, but it is complicated and highly nuanced. We believe the two models proposed here reflect emerging consensus among the range of stakeholders who have been engaging in this discussion and who are dedicated to achieving global HIV prevention goals by ensuring the most appropriate and effective programmes and methods are supported.

RESUMEN

Health economics is a discipline of economics applied to health care. One method used in health economics is decision tree modelling, which extrapolates the cost and effectiveness of competing interventions over time. Such decision tree models are the basis of reimbursement decisions in countries using health technology assessment for decision making. In many instances, these competing interventions are diagnostic technologies. Despite a wealth of excellent resources describing the decision analysis of diagnostics, two critical errors persist: not including diagnostic test accuracy in the structure of decision trees and treating sequential diagnostics as independent. These errors have consequences for the accuracy of model results, and thereby impact on decision making. This paper sets out to overcome these errors using color to link fundamental epidemiological calculations to decision tree models in a visually and intuitively appealing pictorial format. The paper is a must-read for modelers developing decision trees in the area of diagnostics for the first time and decision makers reviewing diagnostic reimbursement models.

RESUMEN

BACKGROUND: Young women in sub-Saharan Africa remain at the epicentre of the HIV epidemic, with surveillance data indicating persistent high levels of HIV incidence. In South Africa, adolescent girls and young women (AGYW) account for a quarter of all new HIV infections. Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS) is a strategy introduced by the United States President's Emergency Plan for AIDS Relief (PEPFAR) aimed at reducing HIV incidence among AGYW in 10 countries in sub-Saharan Africa by 25% in the programme's first year, and by 40% in the second year. This study will assess the change in HIV incidence and reduction in risk associated behaviours that can be attributed to the DREAMS initiative in South Africa, using a population-based cross-sectional survey. METHODS: Data will be collected from a household-based representative sample of AGYW (between the ages 12-24 years) in four high prevalence districts (more than 10% of the population have HIV in these districts) in South Africa in which DREAMS has been implemented. A stratified cluster-based sampling approach will be used to select eligible participants for a cross-sectional survey with 18,500, to be conducted over 2017/2018. A questionnaire will be administered containing questions on sexual risk behaviour, selected academic and developmental milestones, prevalence of gender based violence, whilst examining exposure to DREAMS programmes. Biological samples, including two micro-containers of blood and self-collected vulvovaginal swab samples, are collected in each survey to test for HIV infection, HIV incidence, sexually transmitted infections (STIs) and pregnancy. This study will measure trends in population level HIV incidence using the Limiting antigen (LAg) Avidity Enzyme Immuno-Assay (EIA) and monitor changes in HIV incidence. DISCUSSION: Ending the HIV/AIDS pandemic by 2030 requires the continual monitoring and evaluation of prevention programmes, with the aim of optimising efforts and ensuring the achievement of epidemic control. This study will determine the impact DREAMS interventions have had on HIV incidence among AGYW in a 'real world, non-trial setting'.

RESUMEN

BACKGROUND: Global evidence shows that sexually transmitted infections (STIs) prevalence and sexual risk behaviours are high among youth, and knowledge about STIs is low. In Tanzania, there is limited recent evidence regarding these issues. The aim of this study was to describe the health seeking behaviour of youth reporting STI symptoms in semi-rural Tanzania and to evaluate the association of socio-demographic characteristics, STI knowledge and sexual risk behaviour with STI symptom reporting. METHODS: This was a cross-sectional study involving 2251 sexually experienced youth (15-24 years), who participated in a larger baseline survey of a cohort within Ifakara town. Interview data were electronically collected by trained field workers. Logistic regression analysis was used to identify factors that influence the risk of reporting STI symptoms within the past year, using Stata 12.1. RESULTS: The prevalence of self-reported STI symptoms in the past year was 19.9%. Almost all of youth had heard of STIs and 32.7% of youth could mention at least one sign. 34.4% had sought care for their STI symptoms, the majority at private facilities. Only 20% of HIV-STI co-infected youth was aware of their HIV status. Youth with more knowledge of STI symptoms reported to have had symptoms more often (OR = 1.28; 95% CI 1.01-1.62), and those reporting having first sex at 16 or under were more likely to report STI symptoms than those who delayed to 17-19 years (OR 1.27; 95% CI 1.003-1.62). CONCLUSION: These findings highlight the need to improve the implementation of Adolescent Friendly Health Services available in Tanzania (especially in semi-rural areas). The inclusion of private facilities and pharmacies in AFHS scale-up would potentially raise the level of STI knowledge, lower the STI prevalence and reduce HIV incidence among youth.

RESUMEN

Most HIV research in Sub-Saharan Africa (SSA) ignores persons aged 50 years and above, though a few studies have reported a high HIV prevalence among older people. This study aimed to estimate socio-demographic inequalities in HIV testing behaviour and HIV prevalence among adults aged 50+ years, living in Ifakara town, Tanzania. This cross-sectional study used data from the baseline measurement of the Ifakara MZIMA cohort study in 2012/13. Consenting participants were interviewed and tested for HIV. Associations between HIV testing behaviour and HIV prevalence with socio-demographic indicators were explored with multivariable logistic regression. Among the 1643 adults 50+ years included in the study, HIV prevalence and the HIV testing rate (ever tested) were 6% and 11.4% respectively. The HIV testing rate was lower for older people (aOR = 0.19 (95% CI 0.09-0.41 for 75+ versus 50-54 years); higher for those separated/divorced/widowed than those married (aOR = 1.46; 1.02-2.10); higher for "other Christians" than Muslims (aOR = 1.95; 1.06-3.58); and higher for primary (aOR = 1.54; 1.01-2.33) and secondary (aOR = 3.47; 2.11-5.70) school graduates than those without education. HIV prevalence was lower for older people (aOR = 0.27; 0.11-0.66 for 75+ versus 50-54); and for Catholics compared to Muslims (aOR = 0.54; 0.34-0.85). The high HIV prevalence among older adults and the low HIV testing behaviour call for more efforts on HIV prevention, treatment and care.

RESUMEN

INTRODUCTION: Worldwide, refugees show a poorer mental and physical health than the populations among which they resettle. Little is known about the factors influencing health after resettlement. We examined the development of mental and physical health of refugees. As experienced living difficulties might decrease with obtaining a residence permit, we expected this to play a central role in health improvement after resettlement. METHODS: A two-wave study conducted in the Netherlands among a cohort of 172 recent (n = 68) and longstanding (n = 104) permit holders from Afghanistan, Iran and Somalia between 2003 and 2011. Multivariate mediation analyses were conducted for the effect of changes in living difficulties on the association between change in status and changes in health. Health outcomes were self-reported general health, number of chronic conditions, PTSD and anxiety/depression. RESULTS: Recent permit holders had larger decreases in PTSD score (-0.402, CI -0.612; -0.192) and anxiety/depression score (-0.298, CI -0.464; -0.132), and larger improvements in self-rated general health between T1 and T2 (0.566, CI 0.183; 0.949) than longstanding permit holders. This association was not significant for changes in number of chronic conditions. Mediation analyses showed that the effect of getting a residence permit on health improvements transited through an improvement in living conditions, in particular employment and the presence of family/social support. CONCLUSION: These results suggest that change in residence permit is beneficial for health mainly because of the change in living difficulties. These results add up to the evidence on the role of social circumstances for refugees upon resettlement, and point at labour participation and social support as key mechanisms for health improvements.

RESUMEN

BACKGROUND: A high prevalence of mental and physical ill health among refugees resettled in the Netherlands has been reported. With this study we aim to assess the quality of primary healthcare for resettled refugees in the Netherlands with chronic mental and non-communicable health problems, we examined: a) general practitioners' (GP) recognition of common mental disorders (CMD) (depression and anxiety, and post-traumatic stress disorder (PTSD) symptoms); b) patients' awareness of diabetes type II (DMII) and hypertension (HT); and c) GPs' adherence to guidelines for CMD, DMII and HT. METHODS: From 172 refugees resettled in the Netherlands, interview data (2010-2011) and medical records (n = 106), were examined. Inclusion was based on medical record diagnoses for DMII and HT, and on questionnaire-based CMD measures (Hopkins Symptom Checklist for depression and anxiety; Harvard Trauma Questionnaire for PTSD). GP recognition of CMD was calculated as the number of CMD cases registered in the medical record compared with those found in interviews. Patient awareness of HT and DMII was scored as the percentage of subjects diagnosed by the GP who reported their condition during the interview. GPs' adherence to guidelines for CMD, DMII and HT was measured using established indicators. RESULTS: We identified 37 resettled refugees with CMD of which 18 (49%) had been recognised by the GP. We identified 16 refugees with DMII and 14 with HT from the medical record; 24 (80%) were aware of their condition. Thirty-five out of these 53 (66%) resettled refugees with chronic mental and non-communicable disorders received guideline-adherent treatment. CONCLUSION: This study shows that awareness in resettled refugees of GP diagnosed DMII and HT is high, whereas GP recognition of CMD and overall guideline adherence are moderate.

RESUMEN

BACKGROUND: Post-traumatic stress disorder (PTSD) is a major health problem among refugees worldwide. After resettlement, the prevalence of PTSD remains high despite the fact that various PTSD treatments are known to be effective. METHODS: We examined the course of PTSD and the role of mental health care utilisation at a 7-year interval (2003-2010) among a cohort of refugees from Iran, Afghanistan, and Somalia after resettlement in the Netherlands. RESULTS: The unchanged high prevalence of PTSD (16.3% in 2003 and 15.2% in 2010) was attributable in part to late onset of PTSD symptoms (half of the respondents with PTSD at T2 were new cases for whom PTSD developed after 2003). The second reason concerned the low use of mental health care services at T1. Whereas the multivariate analyses showed the effectiveness of mental health care, only 21% of respondents with PTSD at T1 had had contact with a mental health care provider at that time. Use of mental health care during the first wave increased the odds of improvement in PTSD symptoms between both measurements (OR 7.58, 95% CI 1.01; 56.85). CONCLUSIONS: The findings of this study suggest there are two possible explanations for the persistently high prevalence of PTSD among refugees. One is the late onset of PTSD and the other is the low utilisation of mental health care. Health care professionals should be aware of these issues, especially given the effectiveness of mental health care for this condition.

RESUMEN

The paper aims to estimate the extent to which migrants are contributing to AIDS or tuberculosis (TB) mortality among rural sub-district populations. The Agincourt (South Africa) health and socio-demographic surveillance system provided comprehensive data on vital and migration events between 1994 and 2006. AIDS and TB cause-deleted life expectancy, and crude death rates by gender, migration status and period were computed. The annualised crude death rate almost tripled from 5·39 [95% CI 5·13-5·65] to 15·10 [95% CI 14·62-15·59] per 1000 over the years 1994-2006. The contribution of AIDS and TB in returned migrants to the increase in crude death rate was 78·7% [95% CI 77·4-80·1] for males and 44·4% [95% CI 43·2-46·1] for females. So, in a typical South African setting dependent on labour migration for rural livelihoods, the contribution of returned migrants, many infected with AIDS and TB, to the burden of disease is high.

RESUMEN

BACKGROUND: Migration is difficult to measure because it is highly repeatable. Health and Demographic Surveillance Systems (HDSSs) provide a unique opportunity to study migration as multiple episodes of migration are captured over time. A conceptual framework is needed to show the public health implications of migration. OBJECTIVE/DESIGN: Research conducted in seven HDSS centres [International Network for the Demographic Evaluation of Populations and Their Health (INDEPTH) Network], published in a peer-reviewed volume in 2009, is summarised focussing on the age-sex profile of migrants, the relation between migration and livelihoods, and the impact of migration on health. This illustrates the conceptual structure of the implications of migration. The next phase is described, the Multi-centre Analysis of the Dynamics In Migration And Health (MADIMAH) project, consisting of workshops focussed on preparing data and conducting the analyses for comparative studies amongst HDSS centres in Africa and Asia. The focus here is on the (standardisation of) determinants of migration and the impact of migration on adult mortality. RESULTS: The findings in the volume showed a relatively regular age structure for migration among all HDSS centres. Furthermore, migration generally contributes to improved living conditions at the place of origin. However, there are potential negative consequences of migration on health. It was concluded that there is a need to compare results from multiple centres using uniform covariate definitions as well as longitudinal analysis techniques. This was the starting point for the on-going MADIMAH initiative, which has increased capacity at the participating HDSS centres to produce the required datasets and conduct the analyses. CONCLUSIONS: HDSS centres brought together within INDEPTH Network have already provided strong evidence of the potential negative consequences of migration on health, which contrast with the beneficial impacts of migration on livelihoods. Future comparative evidence using standardised tools will help design policies for mitigating the negative effects, and enhancing the positive effects, of migration on health.

RESUMEN

BACKGROUND: The Foundation for Professional Development (FPD) collects information annually on HIV/AIDS service provision and estimates service needs in the City of Tshwane Metropolitan Municipality (CTMM). METHODS: Antiretroviral therapy (ART) data from the Department of Health and Statistics South Africa (SSA) mid-year population estimates were used to approximate the ART need among adults in the CTMM. RESULTS: According to SSA data, ART need decreased dramatically from 2010 to 2011 and was lower than the number of adults receiving ART. Although the noted difference was probably due to changes in the calculations by SSA, no detailed or confirmed explanation could be offered. CONCLUSIONS: We provide a constructive contribution to the discussion about the use of model-derived estimates of ART need.

RESUMEN

BACKGROUND: Reducing the burden of disease relies on availability of evidence-based clinical practice guidelines (CPGs). There is limited data on availability, quality and content of guidelines within the Southern African Development Community (SADC). This evaluation aims to address this gap in knowledge and provide recommendations for regional guideline development. METHODS: We prioritised five diseases: HIV in adults, malaria in children and adults, pre-eclampsia, diarrhoea in children and hypertension in primary care. A comprehensive electronic search to locate guidelines was conducted between June and October 2010 and augmented with email contact with SADC Ministries of Health. Independent reviewers used the AGREE II tool to score six quality domains reporting the guideline development process. Alignment of the evidence-base of the guidelines was evaluated by comparing their content with key recommendations from accepted reference guidelines, identified with a content expert, and percentage scores were calculated. FINDINGS: We identified 30 guidelines from 13 countries, publication dates ranging from 2003-2010. Overall the 'scope and purpose' and 'clarity and presentation' domains of the AGREE II instrument scored highest, median 58%(range 19-92) and 83%(range 17-100) respectively. 'Stakeholder involvement' followed with median 39%(range 6-75). 'Applicability', 'rigour of development' and 'editorial independence' scored poorly, all below 25%. Alignment with evidence was variable across member states, the lowest scores occurring in older guidelines or where the guideline being evaluated was part of broader primary healthcare CPG rather than a disease-specific guideline. CONCLUSION: This review identified quality gaps and variable alignment with best evidence in available guidelines within SADC for five priority diseases. Future guideline development processes within SADC should better adhere to global reporting norms requiring broader consultation of stakeholders and transparency of process. A regional guideline support committee could harness local capacity to support context appropriate guideline development.

RESUMEN

BACKGROUND: Nine out of ten deaths from malaria occur in sub-Saharan Africa. Various control measures have achieved some progress in the control of the disease, but malaria is still a major public health problem in Africa. Randomized controlled trials (RCTs) are universally considered the best study type to rigorously assess whether an intervention is effective. The study reported here provides a descriptive analysis of RCTs reporting interventions for the prevention and treatment of malaria conducted in Africa, with the aim of providing detailed information on their main clinical and methodological characteristics, that could be used by researchers and policy makers to help plan future research. METHODS: Systematic searches for malaria RCTs were conducted using electronic databases (Medline, Embase, the Cochrane Library), and an African geographic search filter to identify RCTs conducted in Africa was applied. Results were exported to the statistical package STATA 8 to obtain a random sample from the overall data set. Final analysis of trial characteristics was done in a double blinded fashion by two authors using a standardized data extraction form. RESULTS: A random sample of 92 confirmed RCTs (from a total of 943 reports obtained between 1948 and 2007) was prepared. Most trials investigated drug treatment in children with uncomplicated malaria. Few trials reported on treatment of severe malaria or on interventions in pregnant women. Most trials were of medium size (100-500 participants), individually randomized and based in a single centre. Reporting of trial quality was variable. Although three-quarter of trials provided information on participants' informed consent and ethics approval, more details are needed. CONCLUSIONS: The majority of malaria RCT conducted in Africa report on drug treatment and prevention in children; there is need for more research done in pregnant women. Sources of funding, informed consent and trial quality were often poorly reported. Overall, clearer reporting of trials is needed.

RESUMEN

OBJECTIVES: To determine the need for HIV/AIDS service provision in the City of Tshwane Metropolitan Municipality (CTMM), especially in municipal areas. METHODS: The Foundation for Professional Development initiated the Compass Project. Using a questionnaire, data were collected during May - June 2010 from organisations providing HIV/AIDS services in the CTMM (organisational information and types of HIV/AIDS services). The need for HIV counselling and testing (HCT), antiretroviral treatment (ART), prevention of mother-to-child transmission (PMTCT), and care for orphans and vulnerable children (OVC) was estimated using data from various sources. RESULTS: A total of 447 service providers was included in the study: 72.3% non-governmental organisations (NGOs); 18.1% in the public sector; 5.1% in the private sector; and 4.5% faith-based organisations. The majority of the prevention- (70.2%) and support-related services (77.4%) were provided by NGOs, while the majority of treatment-related services originated from the public sector (57.3%). Service need estimates included: HCT - 1 435 438 adults aged 15 - 49 years (11 127/service provider); total ART - 75 211 adults aged 15+ years (1 213/service provider); ART initiation - 30 713 adults aged 15+ years (495/service provider); PMTCT-HCT - 30 092 pregnant women (510/service provider); PMTCT-ART - 7 734 HIV+ pregnant women (221/service provider); and OVC care - 54 590 children (258/service provider). CONCLUSIONS: Service gaps remain in the provision of HCT, PMTCT-ART and OVC care. ART provision must be increased, in light of new treatment guidelines from the Department of Health.

RESUMEN

BACKGROUND: To determine gender differences in health and health care utilisation within and between various ethnic groups in the Netherlands. METHODS: Data from the second Dutch National Survey of General Practice (2000-2002) were used. A total of 7,789 persons from the indigenous population and 1,512 persons from the four largest migrant groups in the Netherlands -- Morocco, Netherlands Antilles, Turkey and Surinam -- aged 18 years and older were interviewed. Self-reported health outcomes studied were general health status and the presence of acute (past 14 days) and chronic conditions (past 12 months). And self-reported utilisation of the following health care services was analysed: having contacted a general practitioner (past 2 months), a medical specialist, physiotherapist or ambulatory mental health service (past 12 months), hospitalisation (past 12 months) and use of medication (past 14 days). Gender differences in these outcomes were examined within and between the ethnic groups, using logistic regression analyses. RESULTS: In general, women showed poorer health than men; the largest differences were found for the Turkish respondents, followed by Moroccans, and Surinamese. Furthermore, women from Morocco and the Netherlands Antilles more often contacted a general practitioner than men from these countries. Women from Turkey were more hospitalised than Turkish men. Women from Morocco more often contacted ambulatory mental health care than men from this country, and women with an indigenous background more often used over the counter medication than men with an indigenous background. CONCLUSION: In general the self-reported health of women is worse compared to that of men, although the size of the gender differences may vary according to the particular health outcome and among the ethnic groups. This information might be helpful to develop policy to improve the health status of specific groups according to gender and ethnicity. In addition, in some ethnic groups, and for some types of health care services, the use by women is higher compared to that by men. More research is needed to explain these differences.

RESUMEN

BACKGROUND: Malaria is endemic in the low-altitude areas of the northern and eastern parts of South Africa with seasonal transmission. The aim of this descriptive study is to give an overview of the malaria incidence and mortality in Limpopo Province for the seasons 1998-1999 to 2006-2007 and to detect trends over time and place. METHODS: Routinely collected data on diagnosed malaria cases and deaths were available through the provincial malaria information system. In order to calculate incidence rates, population estimates (by sex, age and district) were obtained from Statistics South Africa. The Chi squared test for trend was used to detect temporal trends in malaria incidence over the seasons, and a trend in case fatality rate (CFR) by age group. The Chi squared test was used to calculate differences in incidence rate and CFR between both sexes and in incidence by age group. RESULTS: In total, 58,768 cases of malaria were reported, including 628 deaths. The mean incidence rate was 124.5 per 100,000 person-years and the mean CFR 1.1% per season. There was a decreasing trend in the incidence rate over time (p < 0.001), from 173.0 in 1998-1999 to 50.9 in 2006-2007. The CFR was fairly stable over the whole period. The mean incidence rate in males was higher than in females (145.8 versus 105.6; p < 0.001); the CFR (1.1%) was similar for both sexes. The incidence rate was lowest in 0-4 year olds (78.3), it peaked at the ages of 35-39 years (172.8), and decreased with age from 40 years (to 84.4 for those > or = 60 years). The CFR increased with increasing age (to 3.8% for those > or = 60 years). The incidence rate varied widely between districts; it was highest in Vhembe (328.2) and lowest in Sekhukhune (5.5). CONCLUSION: Information from this study may serve as baseline data to determine the course and distribution of malaria in Limpopo province over time. In the study period there was a decreasing trend in the incidence rate. Furthermore, the study addresses the need for better data over a range of epidemic-prone settings.
