RESUMEN

Nicotine is universally recognized as the primary addictive substance fuelling the continued use of tobacco products, which are responsible for over 8 million deaths annually. In recent years, the popularity of newer recreational nicotine products has surged drastically in many countries, raising health and safety concerns. For decades, the tobacco industry has promoted the myth that nicotine is as harmless as caffeine. Nonetheless, evidence shows that nicotine is far from innocuous, even on its own. In fact, numerous studies have demonstrated that nicotine can harm multiple organs, including the respiratory and cardiovascular systems. Tobacco and recreational nicotine products are commercialized in various types and forms, delivering varying levels of nicotine along with other toxic compounds. These products deliver nicotine in profiles that can initiate and perpetuate addiction, especially in young populations. Notably, some electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) can deliver concentrations of nicotine that are comparable to those of traditional cigarettes. Despite being regularly advertised as such, ENDS and HTP have demonstrated limited effectiveness as tobacco cessation aids in real-world settings. Furthermore, ENDS have also been associated with an increased risk of cardiovascular disease. In contrast, nicotine replacement therapies (NRT) are proven to be safe and effective medications for tobacco cessation. NRTs are designed to release nicotine in a slow and controlled manner, thereby minimizing the potential for abuse. Moreover, the long-term safety of NRTs has been extensively studied and documented. The vast majority of tobacco and nicotine products available in the market currently contain nicotine derived from tobacco leaves. However, advancements in the chemical synthesis of nicotine have introduced an economically viable alternative source. The tobacco industry has been exploiting synthetic nicotine to circumvent existing tobacco control laws and regulations. The emergence of newer tobacco and recreational nicotine products, along with synthetic nicotine, pose a tangible threat to established tobacco control policies. Nicotine regulations need to be responsive to address these evolving challenges. As such, governments should regulate all tobacco and non-medical nicotine products through a global, comprehensive, and consistent approach in order to safeguard tobacco control progress in past decades.

RESUMEN

Over the past several decades, the prevalence of cardiovascular disease (CVD) has nearly doubled, and alcohol has played a major role in the incidence of much of it. Alcohol has also been attributed in deaths due to infectious diseases, intentional and unintentional injuries, digestive diseases, and several other non-communicable diseases, including cancer. The economic costs of alcohol-associated health outcomes are significant at the individual as well as the country level. Risks due to alcohol consumption increase for most cardiovascular diseases, including hypertensive heart disease, cardiomyopathy, atrial fibrillation and flutter, and stroke. The widespread message for over 30 years has been to promote the myth that alcohol prolongs life, chiefly by reducing the risk of coronary heart disease (CHD). Lack of universal advice and stringent policy measures have contributed towards increased uptake and easy availability of alcohol. The WHO has called for a 10% relative reduction in the harmful use of alcohol between 2013-2025. However, lack of investment in proven alcohol control strategies, as well as persistence of misinformation and industry interference, have hindered the efforts of public health professionals to make sufficient progress in reducing alcohol related harms and death.

RESUMEN

OBJECTIVE: To understand the factors influencing the implementation of salt reduction interventions in low- and middle-income countries (LMIC). DESIGN: Retrospective policy analysis based on desk reviews of existing reports and semi-structured stakeholder interviews in four countries, using Walt and Gilson's 'Health Policy Triangle' to assess the role of context, content, process and actors on the implementation of salt policy. SETTING: Argentina, Mongolia, South Africa and Vietnam. PARTICIPANTS: Representatives from government, non-government, health, research and food industry organisations with the potential to influence salt reduction programmes. RESULTS: Global targets and regional consultations were viewed as important drivers of salt reduction interventions in Mongolia and Vietnam in contrast to local research and advocacy, and support from international experts, in Argentina and South Africa. All countries had population-level targets and written strategies with multiple interventions to reduce salt consumption. Engaging industry to reduce salt in foods was a priority in all countries: Mongolia and Vietnam were establishing voluntary programs, while Argentina and South Africa opted for legislation on salt levels in foods. Ministries of Health, the WHO and researchers were identified as critical players in all countries. Lack of funding and technical capacity/support, absence of reliable local data and changes in leadership were identified as barriers to effective implementation. No country had a comprehensive approach to surveillance or regulation for labelling, and mixed views were expressed about the potential benefits of low sodium salts. CONCLUSIONS: Effective scale-up of salt reduction programs in LMIC requires: (1) reliable local data about the main sources of salt; (2) collaborative multi-sectoral implementation; (3) stronger government leadership and regulatory processes and (4) adequate resources for implementation and monitoring.

RESUMEN

Stroke is a leading cause of disability, dementia and death worldwide. Approximately 70% of deaths from stroke and 87% of stroke-related disability occur in low-income and middle-income countries. At the turn of the century, the most common diseases in Africa were communicable diseases, whereas non-communicable diseases, including stroke, were considered rare, particularly in sub-Saharan Africa. However, evidence indicates that, today, Africa could have up to 2-3-fold greater rates of stroke incidence and higher stroke prevalence than western Europe and the USA. In Africa, data published within the past decade show that stroke has an annual incidence rate of up to 316 per 100,000, a prevalence of up to 1,460 per 100,000 and a 3-year fatality rate greater than 80%. Moreover, many Africans have a stroke within the fourth to sixth decades of life, with serious implications for the individual, their family and society. This age profile is particularly important as strokes in younger people tend to result in a greater loss of self-worth and socioeconomic productivity than in older individuals. Emerging insights from research into stroke epidemiology, genetics, prevention, care and outcomes offer great prospects for tackling the growing burden of stroke on the continent. In this article, we review the unique profile of stroke in Africa and summarize current knowledge on stroke epidemiology, genetics, prevention, acute care, rehabilitation, outcomes, cost of care and awareness. We also discuss knowledge gaps, emerging priorities and future directions of stroke medicine for the more than 1 billion people who live in Africa.

RESUMEN

Africa is the world's most genetically diverse, second largest, and second most populous continent, with over one billion people distributed across 54 countries. With a 23% lifetime risk of stroke, Africa has some of the highest rates of stroke worldwide and many occur in the prime of life with huge economic losses and grave implications for the individual, family, and the society in terms of mental capital, productivity, and socioeconomic progress. Tackling the escalating burden of stroke in Africa requires prioritized, multipronged, and inter-sectoral strategies tailored to the unique African epidemiological, cultural, socioeconomic, and lifestyle landscape. The African Stroke Organization (ASO) is a new pan-African coalition that brings together stroke researchers, clinicians, and other health-care professionals with participation of national and regional stroke societies and stroke support organizations. With a vision to reduce the rapidly increasing burden of stroke in Africa, the ASO has a four-pronged focus on (1) research, (2) capacity building, (3) development of stroke services, and (4) collaboration with all stakeholders. This will be delivered through advocacy, awareness, and empowerment initiatives to bring about people-focused changes in policy, clinical practice, and public education. In the spirit of the African philosophy of Ubuntu "I am because we are," the ASO will harness the power of diversity, inclusiveness, togetherness, and team work to build a strong, enduring, and impactful platform for tackling stroke in Africa.

RESUMEN

On World Food Day, the World Heart Federation calls on governments to implement mandatory front-of-pack food labels. The World Heart Federation (WHF) has developed a new policy brief on front-of-pack labelling (FOPL) aimed at improving global standards on nutrition and creating healthy food environments. Poor diet is responsible for more deaths worldwide than any other risk factor, and is a leading cause of obesity, type 2 diabetes, and cardiovascular disease (CVD). Global estimates suggest that almost 2.3 billion children and adults are overweight. The growing availability of ultra-processed foods, which contain high levels of sugars, sodium, saturated fats and refined carbohydrates, is a key contributor to the current obesity epidemic, which is increasingly impacting low- and middle-income countries. The WHF Front-of-Pack Labelling Policy Brief highlights front-of-pack labelling as a way to create environments where consumers are able to make better informed, healthier food choices for themselves and their families. Currently, a wide variety of front-of-pack labelling systems have been implemented by governments and food manufacturers around the world, with varying levels of success. The new WHF Policy Brief provides evidence-based, practical guidance that can be adapted to local contexts. It highlights that in order the be implemented successfully, FOPL systems must take into account consumer literacy and prevailing cultural norms around food and nutrition. FOPL must be mandatory, government-led, and accompanied by broad public nutrition education initiatives. The WHF Policy Brief includes a set of policy recommendations to give governments the tools they need to select the FOPL system that will best meet the needs of their populations, including recommendations on how to develop an effective FOPL programme, how to implement it successfully, and how to monitor and evaluate outcomes.

RESUMEN

BACKGROUND: Achieving universal health care coverage will require greater investment in primary health care, particularly in rural and underserved populations in low and middle-income countries. South Africa has invested in training black students from disadvantaged backgrounds in Cuba and large numbers of these Cuban-trained students are now returning for final year and internship training in South Africa. There is controversy about the scheme, the quality and relevance of training received and the place of Cuban-trained doctors in the health care system. Exploring the experiences of Cuban- and South African-trained students, recent graduates and medical school faculty may help understand and resolve the current controversy. METHODS: Using a mixed methods approach, in-depth interviews and a focus group discussion were held with deans of medical schools, senior faculty, and Cuban-trained and South African-trained students and recent graduates. An online structured questionnaire, adapted from the USA medical student survey, was developed and administered to Cuban- and South African-trained students and recent graduates. RESULTS: South African students trained in Cuba have had beneficial experiences which orientate them towards primary health care and prevention. Their subsequent training in South Africa is intended to fill skill gaps related to TB, HIV and major trauma. However this training is ad hoc and variable in duration and demoralizing for some students. Cuban-trained students have stronger aspirations than those trained in South Africa to work in rural and underserved communities from which many of them are drawn. CONCLUSION: Attempts to assimilate returning Cuban-trained students will require a reframing of the current negative narrative by focusing on positive aspects of their training, orientation towards primary care and public health, and their aspirations to work in rural and under-served urban areas. Cuban-trained doctors could be part of the solution to South Africa's health workforce problems.

RESUMEN

Objective: To explore the perceived barriers and facilitators for healthy behaviours among parents and caregivers of adolescents receiving mental health care in Cape Town, South Africa. Method: Thirty-five qualitative in-depth interviews were conducted with parents and caregivers of adolescents receiving mental health treatment by six facilitators matched for language. The data was analysed using thematic analysis. Results: The participants were predominantly female (n = 28, 80%) and parents (n = 29, 83%) of the adolescents. Personal barriers to good health included unhealthy eating, substance use and physical inactivity. Environmental barriers were inherited medical conditions, the easy availability of unhealthy foods and the absence of recreational facilities in communities. Perceived facilitators to good health were parental role modelling, planning and preparing healthy meals, exercise opportunities providing by walking long distances to work, and doing physically demanding jobs and household chores. Conclusion: Parents and caregivers are essential to adolescents' healthy development as they may influence adolescent health behaviours. It is likely that the promotion of positive health behaviours may be achieved though family-based interventions.

RESUMEN

AIMS: To describe the distribution and examine the associations of diabetes, hypertension and hypercholesterolaemia across and within population groups, gender and body mass index (BMI) categories. METHODS: This national cross-sectional study was conducted in 2013 among ≥18-year-old black African, coloured, white and Indian adults self-selected for screening. Data collection included self-reported behavioural risk factors and clinical measurements comprising blood pressure, anthropometry and point-of-care random blood glucose and cholesterol assessments. RESULTS: Among the 7711 participants, 2488 men and 5223 women, the prevalence of diabetes and hypertension increased by BMI category across population groups. Compared with white men and women, black African men (odds ratio: 2.66, 95% confidence interval: 1.70-4.16) and women (2.10, 1.49-2.96), coloured men (2.28, 1.44-3.60) and women (2.15, 1.52-3.05) and Indian men (4.38, 2.65-7.26) and women (3.64, 2.50-5.32) were significantly more likely to have diabetes. The odds for hypertension were significantly higher only in coloured men compared with white men (1.37, 1.02-1.83), while it was significantly higher in black African, coloured and Indian women compared with white women. The odds for hypercholesterolaemia were significantly lower in black African men (0.64, 0.49-0.84) and women (0.52, 0.43-0.62) compared with white men and women, and significantly higher in Indian men (1.47, 1.05-2.08) compared with white men. Black African women compared with their male counterparts were less likely to have diabetes (0.64, 0.46-0.89). Black African (0.66, 0.54-.082), coloured (0.65, 0.50-0.84) and white (0.69, 0.53-0.88) women were significantly less likely to have hypertension compared with their male counterparts. The odds for hypercholesterolaemia were higher in coloured (1.44, 1.16-1.80) and white (1.47, 1.18-1.84) women compared with their counterparts. CONCLUSIONS: The cardio-metabolic diseases of diabetes, hypertension and hypercholesterolaemia were differentially associated with population groups and gender in South Africa. The insights obtained highlight the need for multi-disciplinary targeted management approaches in high-risk populations.

RESUMEN

BACKGROUND: The HealthRise initiative seeks to implement and evaluate innovative community-based strategies for diabetes, hypertension and hypercholesterolemia along the entire continuum of care (CoC)-from awareness and diagnosis, through treatment and control. In this study, we present baseline findings from HealthRise South Africa, identifying gaps in the CoC, as well as key barriers to care for non-communicable diseases (NCDs). METHODS: This mixed-methods needs assessment utilized national household data, health facility surveys, focus group discussions, and key informant interviews in Umgungundlovu and Pixley ka Seme districts. Risk factor and disease prevalence were estimated from the South Africa National Health and Nutrition Examination Survey. Health facility surveys were conducted at 86 facilities, focusing on essential intervention, medications and standard treatment guidelines. Quantitative results are presented descriptively, and qualitative data was analyzed using a framework approach. RESULTS: 46.8% of the population in Umgungundlovu and 51.0% in Pixley ka Seme were hypertensive. Diabetes was present in 11.0% and 9.7% of the population in Umgungundlovu and Pixley ka Seme. Hypercholesterolemia was more common in Pixley ka Seme (17.3% vs. 11.1%). Women and those of Indian descent were more likely to have diabetes. More than half of the population was found to be overweight, and binge drinking, inactivity and smoking were all common. More than half of patients with hypertension were unaware of their disease status (51.6% in Pixley ka Seme and 51.3% in Umgungundlovu), while the largest gap in the diabetes CoC occurred between initiation of treatment and achieving disease control. Demand-side barriers included lack of transportation, concerns about confidentiality, perceived discrimination and long wait times. Supply-side barriers included limited availability of testing equipment, inadequate staffing, and pharmaceutical stock outs. CONCLUSION: In this baseline assessment of two South African health districts we found high rates of undiagnosed hypercholesterolemia and hypertension, and poor control of hypercholesterolemia, hypertension, and diabetes. The HealthRise Initiative will need to address key supply- and demand-side barriers in an effort to improve important NCD outcomes.

RESUMEN

This study examines the associations between symptoms of mental disorders and diabetes and hypertension in a nationally representative sample of South Africans. We examined unadjusted and adjusted associations of socio-demographic characteristics, alcohol use and psychological distress with diabetes and hypertension. Multivariate logistic regression revealed that hypertension is significantly associated with age, while diabetes is significantly associated with age, population group and psychological distress. The association between psychological distress and diabetes found here suggests the usefulness of additional research using more detailed measures of psychiatric disorders in local studies and reinforces clinical calls for attention to psychiatric screening in patients with diabetes.

RESUMEN

Poor mental health in adolescents has shown associations with engagement in other risk behaviours. However, evidence of this association in Sub-Saharan Africa, particularly South Africa, is lacking. This study examines the associations between pertinent risk behaviours and feelings of sadness or hopelessness amongst a nationally representative sample of South African school going adolescents. Data was analysed from the South African Youth Risk Behaviour Survey 2011 (n=10,997), a cross-sectional national survey among grades 8-11 school learners. Logistic regression examined the association of demographic, substance use, violent behaviour, sexual activity and suicidal plans and attempts with the primary outcome, feelings of sadness or hopelessness. Having feelings of sadness or hopelessness was significantly associated with more senior grades, being bullied (AOR:1.67, 95% CI: 1.42-1.96), being assaulted by a partner (1.33 [1.05-1.68]), forced sex (1.78 [1.37-2.32]); gang membership (1.32 [1.06-1.65]), binge drinking (1.37 [1.14-1.65]), ever having sex (1.23 [1.02-1.47]), having ≥1 partner/s in preceding three months (1.25 [1.02-1.53]), having made a plan to attempt suicide (2.50 [1.95-3.21]) and suicide attempt (1.49 [1.21-1.85]). Adolescents in South Africa are experiencing a multiple burden of risk. Health promotion strategies targeting adolescent mental health and risk behaviours need to be developed and implemented in a timely and comprehensive manner.

RESUMEN

BACKGROUND: Adolescent mothers are at a much higher risk for maternal mortality compared to mothers aged 20 years and above. Newborns born to adolescent mothers are also more likely to have low birth weight, with the risk of long-term effects such as early onset of adult diabetes than newborns of older mothers. Few studies have investigated the determinants of adequate quality maternal and child healthcare services to pregnant adolescents. This study was conducted to gain an understanding of nurses' and midwives' intentions to provide maternal and child healthcare and family planning services to adolescents in South Africa. METHODS: A total of 190 nurses and midwives completed a cross-sectional survey. The survey included components on demographics, knowledge of maternal and child healthcare (MCH) and family planning (FP) services, attitude towards family planning services, subjective norms regarding maternal and child healthcare and family planning services, self-efficacy with maternal and child healthcare and family planning services, and intentions to provide maternal and child healthcare and family planning services to adolescents. Pearson's correlation analysis was conducted to determine the association between knowledge, attitude, subjective norms, self-efficacy, and intention variables for FP and MCH services. A 2-step linear regression analysis was then conducted for both FP and MCH services to predict the intentions to provide FP and MCH services to adolescents. RESULTS: Self-efficacy to conduct MCH services (ß = 0.55, p < 0.01) and years of experience as a nurse- midwife (ß = 0.14, p < 0.05) were associated with stronger intentions to provide the services. Self-efficacy to provide FP services (ß = 0.30, p < 0.01) was associated with stronger intentions to provide FP services. CONCLUSIONS: Self-efficacy has a strong and positive association with the intentions to provide both MCH and FP services, while there is a moderate association with attitude and norms. There is a need to improve and strengthen nurses' and midwives' self-efficacy in conducting both MCH and FP services in order to improve the quality and utilization of the services by adolescents in South Africa.

RESUMEN

BACKGROUND: South Africa is one of the 22 high tuberculosis burden countries that contribute 80% of the global tuberculosis cases. Tuberculosis is infectious and due to its rapid and easy transmission route poses a threat to population health. Considering the importance of social and psychological factors in influencing health outcomes, appraising knowledge and awareness of tuberculosis, remain vital for effective tuberculosis control. The main aim of this study was to investigate the factors that predict knowledge about tuberculosis among 18-64 year old adults in South Africa. METHODS: A cross-sectional survey method was used. Multi-stage disproportionate, stratified cluster sampling was used to select households within enumeration areas stratified by province and locality type. Based on the Human Sciences Research Council 2007 master sample, 500 Enumerator Areas representative of the socio-demographic profile of South Africa were identified and a random sample of 20 households was randomly selected from each Enumerator Area, yielding an overall sample of 10,000 households. The tuberculosis module contained in the South African National Health And Nutrition Examination Survey I was the only module that examined the social determinants of an infectious disease. This module was questionnaire-based with no biomarkers obtained to screen for the presence of tuberculosis disease among the participants. Data was collected by administering a researcher developed individual level questionnaire. Simple and multiple linear regression was used to determine the independent variables associated with tuberculosis knowledge. RESULTS: Half the sample (52.6%) was female and the majority of the respondents were black African (76.5%). More than two thirds (68.0%) resided in urban areas, 56.9% did not complete high school and half were not in formal employment. Significant predictors of tuberculosis knowledge were race, sex, completion of high school, being in employment, having a diagnosis of the disease in ones' life-time and learning about tuberculosis from television, brochures, health workers, and teachers. CONCLUSIONS: To reduce the burden of tuberculosis in South Africa, media campaigns targeting both rural and urban communities should include conveying accurate information about the disease. Policy makers should also address structural barriers that vulnerable communities face.

RESUMEN

BACKGROUND: The successful cure of tuberculosis (TB) is dependent on adherence to treatment. Various factors influence adherence, however, few are easily modifiable. There are limited data regarding correlates of psychological distress and their association with non-adherence to anti-TB treatment. METHODS: In a trial of a new TB test, we measured psychological distress (K-10 score), TB-related health literacy, and morbidity (TBscore), prior to diagnosis in 1502 patients with symptoms of pulmonary TB recruited from clinics in Cape Town (n = 419), Harare (n = 400), Lusaka (n = 400), Durban (n = 200), and Mbeya (n = 83). Socioeconomic, demographic, and alcohol usage-related data were captured. Patients initiated on treatment had their DOTS cards reviewed at two-and six-months. RESULTS: 22 %(95 % CI: 20 %, 25 %) of patients had severe psychological distress (K-10 ≥ 30). In a multivariable linear regression model, increased K-10 score was independently associated with previous TB [estimate (95 % CI) 0.98(0.09-1.87); p = 0.0304], increased TBscore [1(0.80, 1.20); p <0.0001], and heavy alcohol use [3.08(1.26, 4.91); p = 0.0010], whereas male gender was protective [-1.47(-2.28, -0.62); p = 0.0007]. 26 % (95 % CI: 21 %, 32 %) of 261 patients with culture-confirmed TB were non-adherent. In a multivariable logistic regression model for non-adherence, reduced TBscore [OR (95 % CI) 0.639 (0.497, 0.797); p = 0.0001], health literacy score [0.798(0.696, 0.906); p = 0.0008], and increased K-10 [1.082(1.033, 1.137); p = 0.0012], and heavy alcohol usage [14.83(2.083, 122.9); p = 0.0002], were independently associated. Culture-positive patients with a K-10 score ≥ 30 were more-likely to be non-adherent (OR = 2.290(1.033-5.126); p = 0.0416]. CONCLUSION: Severe psychological distress is frequent amongst TB patients in Southern Africa. Targeted interventions to alleviate psychological distress, alcohol use, and improve health literacy in newly-diagnosed TB patients could reduce non-adherence to treatment.

RESUMEN

There is increasing focus on social and structural factors following the marginal success of individual-level strategies for HIV prevention. While there is evidence of decreased HIV prevalence among young individuals in South Africa, there is still a need to monitor HIV incidence and prevalence in this vulnerable group as well as track and prevent high-risk sexual behavior(s). This study investigated the social and structural factors that shape the context of vulnerability to increased risk of exposure to HIV infection. A mixed-methods approach including qualitative and quantitative design components was employed. Young adults in the age group 18-24 were interviewed from four provinces in South Africa. The qualitative results produced strong support for the effectiveness of loveLife's HIV prevention programs. The household-based survey results showed that the strongest predictors of self-reported HIV infection (indicating a greater chance of being infected) using adjusted odds ratios (aOR) are: being diagnosed with an STI in a lifetime (aOR 13.68 95% Confidence Interval (CI) [4.61-40.56]; p < .001), inconsistent condom use (aOR 6.27 95% CI [2.08-18.84]; p < .01), and difficulty in accessing condoms (aOR 2.86 95% CI [1.04-7.88]; p < .05). The strongest predictors that indicated a decreased chance of being infected with the HI virus are: talking with partner about condom use in the past 12 months (aOR .08 95% CI [.02-.36]; p < .001) and having a grade 8 (aOR .04 95% CI [.01-.66]; p < .05) and higher educational level (aOR .04 95% CI [.01-.43]). These results show that social and structural factors serve as risk and protective factors for HIV prevention among young people. Intervention programs need to continue to focus on effective communication strategies and healthy relationships. Structural adjustments have to be made to encourage school attendance. Finally, social/health policies and health service delivery have to also be refined so that young people have access to youth friendly health services.

RESUMEN

High risk sexual behaviour, alcohol and drug use, and mental health problems combine to yield high levels of HIV-risk behaviour among adolescents with mental health problems. In South Africa, little research has been conducted on parental perspectives of HIV-risk among this population. We conducted a series of focus group discussions with 28 mothers of adolescents receiving services at two mental health clinics in South Africa to identify, from their perspectives, the key community problems facing their children. Participants indicated that HIV remained a serious threat to their adolescent children's well-being, in addition to substance abuse, early sexual debut, and teenage pregnancy. These social problems were mentioned as external to their household dynamics, and thus seemingly beyond the purview of the parent-adolescent relationship. These data have implications for the design of family-based interventions to ameliorate the factors associated with HIV-risk among youth receiving mental health services.
