RESUMO

Background: Evidence from sub-Saharan Africa (SSA) regarding risky behaviors among adolescents remains scarce, despite the large population (approximately 249 million out of 1.2 billion globally in 2019) of adolescents in the region. We aimed to examine the potential influence of depressive symptoms and school-going status on risky behaviors among adolescents in six SSA countries. Methods: We used individual cross-sectional data from adolescents aged 10-19 based in eight communities across six SSA countries, participating in the ARISE Network Adolescent Health Study (N = 7,661). Outcomes of interest were cigarette or tobacco use, alcohol use, other substance use, getting into a physical fight, no condom use during last sexual intercourse, and suicidal behavior. We examined the proportion of adolescents reporting these behaviors, and examined potential effects of depressive symptoms [tertiles of 6-item Kutcher Adolescent Depression Scale (KADS-6) score] and school-going status on these behaviors using mixed-effects Poisson regression models. We also assessed effect modification of associations by sex, age, and school-going status. Results: The proportion of adolescents reporting risky behaviors was varied, from 2.2% for suicidal behaviors to 26.2% for getting into a physical fight. Being in the higher tertiles of KADS-6 score was associated with increased risk of almost all risky behaviors [adjusted risk ratio (RR) for highest KADS-6 tertile for alcohol use: 1.70, 95% confidence interval (95% CI): 1.48-1.95, p < 0.001; for physical fight: 1.52, 95% CI: 1.36-1.70, p < 0.001; for suicidal behavior: 7.07, 95% CI: 2.69-18.57, p < 0.001]. Being in school was associated with reduced risk of substance use (RR for alcohol use: 0.73, 95% CI: 0.53-1.00, p = 0.047), and not using a condom (RR: 0.81, 95% CI: 0.66-0.99, p = 0.040). There was evidence of modification of the effect of school-going status on risky behaviors by age and sex. Conclusion: Our findings reinforce the need for a greater focus on risky behaviors among adolescents in SSA. Addressing depressive symptoms among adolescents, facilitating school attendance and using schools as platforms to improve health may help reduce risky behaviors in this population. Further research is also required to better assess the potential bidirectionality of associations.

RESUMO

PURPOSE: Self-report of sensitive or stigmatized health states is often subject to social desirability and interviewer biases. To reduce such biases, we estimated the rate of sexually transmitted infections (STIs) using a list experiment. METHODS: This population-representative study was nested within the Dar es Salaam Urban Cohort Study, a Health and Demographic Surveillance System (HDSS) in the Ukonga ward of Dar es Salaam, Tanzania. Men and women aged ≥40years were randomly assigned to receive a list of either four control items (i.e., the control group) or four control items plus an additional item on having had a disease through sexual contacts in the past 12months (i.e., the treatment group). We calculated the mean difference in the total number of items to which respondents answered "yes" in the treatment versus control group and compared this prevalence estimate to the one measured by the direct question. RESULTS: A total of 2310 adults aged ≥40years were enrolled in the study: 32% were male and 48% were aged 40-49years. The estimated prevalence of having STIs in the past 12months was 17.8% (95% confidence interval [CI] 12.3-23.3) in the list experiment, almost 10 times higher than the estimated prevalence of 1.8% (95%CI 1.3-2.4) based on the direct question (P < .001). STI prevalence remained high after adjusting for age, the number of lifetime sex partners, alcohol consumption and smoking in multivariate linear regression (15.6%; 95% CI 7.3-23.9). CONCLUSIONS: We found a substantially higher prevalence of STIs among older adults in urban Tanzania when we based our estimation on a list experiment rather than a direct question in a population-representative survey. List experiments should be considered to elimnate social desirability and interviewer biases in surveys of sensitive or stigmatized health states. The very high prevalence of STIs highlights the need for improved access to STI screening, prevention and treatment for older adults in urban Africa.

RESUMO

The ARISE Network Adolescent Health Study is an exploratory, community-based survey of 8075 adolescents aged 10-19 in 9 communities in 7 countries: Burkina Faso, Eswatini, Ethiopia, Ghana, Nigeria, Tanzania and Uganda. Communities were selected opportunistically and existing population cohorts maintained by health and demographic surveillance systems (HDSSs). The study is intended to serve as a first round of data collection for African adolescent cohorts, with the overarching goal of generating community-based data on health-related behaviours and associated risk factors in adolescents, to identify disease burdens and health intervention opportunities. Household-based sampling frames were used in each community to randomly select eligible adolescents (aged 10-19 years). Data were collected between July 2015 and December 2017. Consenting participants completed face-to-face interviews with trained research assistants using a standardised questionnaire, which covered physical activity, cigarette and tobacco use, substance and drug use, mental health, sexual behaviours and practices, sexually transmitted infections, pregnancy, food security and food diversity, teeth cleaning and hand washing, feelings and friendship, school and home activities, physical attacks and injuries, health care, health status assessment and life satisfaction, as well as media and cell phone use and socio-demographic and economic background characteristics. Results from this multi-community study serve to identify major adolescent health risks and disease burdens, as well as opportunities for interventions and improvements through policy changes.


L'étude ARISE du réseau sur la santé des adolescents est une étude exploratoire de surveillance basée sur la communauté portant sur 8.075 adolescents âgés de 10 à 19 ans dans 9 communautés de 7 pays: Burkina Faso, Eswatini, Ethiopie, Ghana, Nigéria, Tanzanie et Ouganda. Les communautés ont été sélectionnés de manière opportuniste et les cohortes de population existantes maintenues par des systèmes de surveillance de la santé et démographique (SSSD). L'étude est destinée à servir comme premier cycle de collecte de données pour les cohortes d'adolescents africains, dans le but primordial de générer des données communautaires sur les comportements liés à la santé et les facteurs de risque associés chez les adolescents, afin d'identifier la charge de morbidité et les opportunités d'intervention en matière de santé. Des cadres d'échantillonnage basés sur le ménage ont été utilisés dans chaque communauté pour sélectionner au hasard les adolescents admissibles (âgés de 10-19 ans). Les données ont été collectées entre juillet 2015 et décembre 2017. Les participants consentants ont participé à des entretiens de face à face avec des assistants de recherche formés, à l'aide d'un questionnaire standardisé couvrant l'activité physique, l'usage de la cigarette ou la consommation de tabac, l'usage de drogues et autres substances, la santé mentale, les comportements et pratiques sexuels, les infections sexuellement transmissibles, la grossesse, la sécurité et la diversité alimentaire, le nettoyage des dents et le lavage des mains, les sentiments et les amitiés, les activités scolaires et à domicile, les attaques et les blessures physiques, les soins de santé, l'évaluation de l'état de santé et la satisfaction à l'égard de la vie, l'utilisation des médias et du téléphone portable ainsi que les caractéristiques sociodémographiques et économiques. Les résultats de cette étude portant sur plusieurs communautés permettent d'identifier les principaux risques pour la santé des adolescents et les charges de morbidité, ainsi que les opportunités d'interventions et d'amélioration par le biais de changements de politiques.

RESUMO

OBJECTIVE: To measure health-related behaviours and risk factors among sub-Saharan African adolescents. METHODS: Cross-sectional study in nine communities in Burkina Faso, Ethiopia, Eswatini, Ghana, Nigeria, Tanzania and Uganda between 2015 and 2017. Community-representative samples of males and females 10-19 years of age were selected. All communities used a uniform questionnaire that was adapted from the WHO Global School-based Student Health Survey. Weighted prevalence estimates and 95% confidence intervals were calculated for each indicator and stratified by age and sex using SAS version 9.4. All prevalence estimates were pooled across communities through random-effects meta-analyses in Stata version 14. RESULTS: A total of 8075 adolescents participated in the study. We observed a high prevalence of inadequate fruit consumption (57-63%) and low physical activity (82-90%); a moderate prevalence of inadequate vegetable consumption (21-31%), unprotected last sex (38-45%), age at first sex <15 years (21-28%) and bullying and physical fighting (12-35%); and a low prevalence of mental health risk factors (1-11%) and alcohol and substance use risk factors (0-6%). We observed a moderate to high prevalence of daily soft drink consumption (21-31%) for all adolescents. Among sexually active adolescents 15-19 years, 37% of females reported ever being pregnant and 8% of males reported to have ever made someone pregnant. Bullying (23%) and physical fighting (35%) were more common among younger male adolescents . The prevalence of low mood was generally higher among older (15-19 years) than younger adolescents (10-14 years). The proportion of adolescents reporting alcohol, drug or cigarette use was very small, with the exception of khat use in Ethiopia. CONCLUSION: Overall, diet and physical activity, violence, sexual and reproductive health, and depression are important risk factors for these sub-Saharan African communities. These findings suggest that more evidence is needed including novel efforts for the collection of sensitive information, as well as a need to move towards community-tailored interventions to reach adolescent populations with varying needs.


OBJECTIF: Mesurer les comportements liés à la santé et les facteurs de risque chez les adolescents africains subsahariens. MÉTHODES: Etude transversale dans neuf communautés au Burkina Faso, en Ethiopie, à Eswatini, au Ghana, au Nigéria, en Tanzanie et en Ouganda entre 2015 et 2017. Des échantillons représentatifs de la communauté composés d'hommes et de femmes âgés de 10 à 19 ans ont été sélectionnés. Toutes les communautés ont utilisé un questionnaire uniforme adapté de l'Enquête Mondiale sur la Santé des Elèves de l'OMS. Les estimations de prévalence pondérée et les intervalles de confiance à 95% ont été calculés pour chaque indicateur et stratifiées par âge et sexe à l'aide de la version 9.4 de SAS. Toutes les estimations de prévalence ont été poolées dans les communautés via des méta-analyses à effets aléatoires dans Stata, version 14. RÉSULTATS: 8.075 adolescents ont participé à l'étude. Nous avons observé une prévalence élevée de consommation insuffisante de fruits (57-63%) et de faible activité physique (82-90%); une prévalence modérée de consommation insuffisante de légumes (21-31%), du dernier rapport sexuel non protégé (38-45%), du premier rapport sexuel à moins de 15 ans (21-28%) et de l'intimidation et des combats physiques (12-35%), une faible prévalence de facteurs de risque pour la santé mentale (1-11%) et de facteurs de risque pour la consommation d'alcool et de substances (0-6%). Nous avons observé une prévalence modérée à élevée de consommation quotidienne de boissons gazeuses (21-31%) chez tous les adolescents. Parmi les adolescents sexuellement actifs âgées de 15 à 19 ans, 37,0% des femmes ont déclaré avoir déjà été enceintes et 8,0% des hommes ont rapporté avoir déjà enceinté une femme. L'intimidation (23%) et les combats physiques étaient plus fréquents chez les adolescents plus jeunes (35%). La prévalence de la mauvaise humeur était généralement plus élevée chez les adolescents d'âge plus élevé (de 15 à 19 ans) que chez les plus jeunes (de 10 à 14 ans). La proportion d'adolescents déclarant avoir consommé de l'alcool, des drogues ou des cigarettes était très faible, à l'exception de la consommation de khat en Ethiopie. CONCLUSION: Dans l'ensemble, le régime alimentaire et l'activité physique, la violence, la santé sexuelle et reproductive et la dépression sont des facteurs de risque importants pour ces communautés d'Afrique subsaharienne. Ces résultats suggèrent que davantage de données sont nécessaires, notamment de nouveaux efforts pour la collecte d'informations sensibles, ainsi que la nécessité de passer à des interventions adaptées aux communautés pour atteindre les populations adolescentes avec des besoins variés.

RESUMO

BACKGROUND: Sickle cell disease (SCD) is a recognized cause of childhood mortality. Tanzania has the fifth highest incidence of SCD (with an estimated 11 000 SCD annual births) worldwide. Although newborn screening (NBS) for SCD and comprehensive healthcare have been shown to reduce under-5 mortality by up to 94% in high-income countries such as the USA, no country in Africa has maintained NBS for SCD as a national health program. The aims of this program were to establish and evaluate NBS-SCD as a health intervention in Tanzania and to determine the birth prevalence of SCD. METHODS: Muhimbili University of Health and Allied Sciences conducted NBS for SCD from January 2015 to November 2016. Dried blood spot samples were collected and tested for SCD using isoelectric focusing. RESULTS: Screening was conducted on 3981 newborns. Thirty-one (0.8%) babies had SCD, 505 (12.6%) had sickle cell trait and 26 (0.7%) had other hemoglobinopathies. Twenty-eight (90.3%) of the 31 newborns with SCD were enrolled for comprehensive healthcare. CONCLUSIONS: This is the first report on NBS as a health program for SCD in Tanzania. The SCD birth prevalence of 8 per 1000 births is of public health significance. It is therefore important to conduct NBS for SCD with enrollment into a comprehensive care program.

RESUMO

BACKGROUND: Integration of HIV into RMNCH (reproductive, maternal, newborn and child health) services is an important process addressing the disproportionate burden of HIV among mothers and children in sub-Saharan Africa. We assess the structural inputs and processes of care that support HIV testing and counselling in routine antenatal care to understand supply-side dynamics critical to scaling up further integration of HIV into RMNCH services prior to recent changes in HIV policy in Tanzania. METHODS: This study, as a part of a maternal and newborn health program evaluation in Morogoro Region, Tanzania, drew from an assessment of health centers with 18 facility checklists, 65 quantitative and 57 qualitative provider interviews, and 203 antenatal care observations. Descriptive analyses were performed with quantitative data using Stata 12.0, and qualitative data were analyzed thematically with data managed by Atlas.ti. RESULTS: Limitations in structural inputs, such as infrastructure, supplies, and staffing, constrain the potential for integration of HIV testing and counselling into routine antenatal care services. While assessment of infrastructure, including waiting areas, appeared adequate, long queues and small rooms made private and confidential HIV testing and counselling difficult for individual women. Unreliable stocks of HIV test kits, essential medicines, and infection prevention equipment also had implications for provider-patient relationships, with reported decreases in women's care seeking at health centers. In addition, low staffing levels were reported to increase workloads and lower motivation for health workers. Despite adequate knowledge of counselling messages, antenatal counselling sessions were brief with incomplete messages conveyed to pregnant women. In addition, coping mechanisms, such as scheduling of clinical activities on different days, limited service availability. CONCLUSION: Antenatal care is a strategic entry point for the delivery of critical tests and counselling messages and the framing of patient-provider relations, which together underpin care seeking for the remaining continuum of care. Supply-side deficiencies in structural inputs and processes of delivering HIV testing and counselling during antenatal care indicate critical shortcomings in the quality of care provided. These must be addressed if integrating HIV testing and counselling into antenatal care is to result in improved maternal and newborn health outcomes.

RESUMO

BACKGROUND: Women and children in sub-Saharan Africa bear a disproportionate burden of HIV/AIDS. Integration of HIV with maternal and child services aims to reduce the impact of HIV/AIDS. To assess the potential gains and risks of such integration, this paper considers pregnant women's and providers' perceptions about the effects of integrated HIV testing and counselling on care seeking by pregnant women during antenatal care in Tanzania. METHODS: From a larger evaluation of an integrated maternal and newborn health care program in Morogoro, Tanzania, this analysis included a subset of information from 203 observations of antenatal care and interviews with 57 providers and 190 pregnant women from 18 public health centers in rural and peri-urban settings. Qualitative data were analyzed manually and with Atlas.ti using a framework approach, and quantitative data of respondents' demographic information were analyzed with Stata 12.0. RESULTS: Perceptions of integrating HIV testing with routine antenatal care from women and health providers were generally positive. Respondents felt that integration increased coverage of HIV testing, particularly among difficult-to-reach populations, and improved convenience, efficiency, and confidentiality for women while reducing stigma. Pregnant women believed that early detection of HIV protected their own health and that of their children. Despite these positive views, challenges remained. Providers and women perceived opt out HIV testing and counselling during antenatal services to be compulsory. A sense of powerlessness and anxiety pervaded some women's responses, reflecting the unequal relations, lack of supportive communications and breaches in confidentiality between women and providers. Lastly, stigma surrounding HIV was reported to lead some women to discontinue services or seek care through other access points in the health system. CONCLUSION: While providers and pregnant women view program synergies from integrating HIV services into antenatal care positively, lack of supportive provider-patient relationships, lack of trust resulting from harsh treatment or breaches in confidentiality, and stigma still inhibit women's care seeking. As countries continue rollout of Option B+, social relations between patients and providers must be understood and addressed to ensure that integrated delivery of HIV counselling and services encourages women's care seeking in order to improve maternal and child health.

RESUMO

BACKGROUND: This paper presents the prevalence of human immunodeficiency virus (HIV) and syphilis infections among women attending antenatal clinics (ANC) in Tanzania obtained during the 2003/2004 ANC surveillance. METHODS: Ten geographical regions; six of them were involved in a previous survey, while the remaining four were freshly selected on the basis of having the largest population among the remaining 20 regions. For each region, six ANC were selected, two from each of three strata (urban, peri-urban and rural). Three of the sites did not participate, resulting into 57 surveyed clinics. 17,813 women who were attending the chosen clinics for the first time for any pregnancy between October 2003 and January 2004. Patient particulars were obtained by interview and blood specimens were drawn for HIV and syphilis testing. HIV testing was done anonymously and the results were unlinked. RESULTS: Of the 17,813 women screened for HIV, 1,545 (8.7% (95% CI = 8.3-9.1)) tested positive with the highest prevalence in women aged 25-34 years (11%), being higher among single women (9.7%) than married women (8.6%) (p < 0.07), and increased with level of education from 5.2% among women with no education to 9.3% among those at least primary education (p < 0.001). Prevalence ranged from 4.8% (95% CI = 3.8%-9.8%) in Kagera to 15.3% (95% CI = 13.9%-16.8%) in Mbeya and was; 3.7%, 4.7%, 9.1%, 11.2% and 15.3% for rural, semi-urban, road side, urban and 15.3% border clinics, respectively (p < 0.001). Of the 17,323 women screened for syphilis, 1265 (7.3% (95%CI = 6.9-7.7)) were positive, with highest prevalence in the age group 35-49 yrs (10.4%) (p < 0.001), and being higher among women with no education than those with some education (9.8% versus 6.8%) (p < 0.0001), but marital status had no influence. Prevalence ranged from 2.1% (95% CI = 1.4%-3.0%) in Kigoma to 14.9% (95% CI = 13.3%-16.6%) in Kagera and was 16.0% (95% CI = 13.3-18.9), 10.5% (95% CI = 9.5-11.5) and 5.8% (95% CI = 5.4-6.3) for roadside, rural and urban clinics, respectively. Syphilis and HIV co-infection was seen in 130/17813 (0.7%). CONCLUSION: The high HIV prevalence observed among the ANC clinic attendees in Tanzania call for expansion of current voluntary counselling and testing (VCT) services and access to antiretroviral drugs (ARV) in the clinics. There is also a need for modification of obstetric practices and infant feeding options in HIV infection in order to prevent mother to child transmission of HIV. To increase uptake to HIV testing the opt-out strategy in which all clients are offered HIV testing is recommended in order to meet the needs of as many pregnant women as possible.
