A Cross-sectional Study of Self-Perceived Educational Needs of Emergency Nurses in Two Tertiary Hospitals in Nairobi, Kenya.

BACKGROUND: Many low- and middle-income countries lack resources for well-functioning emergency care systems. Emergency nurses interact with injured and critically ill patients as the first contact in many health care settings. However, insufficient training limits nurses from providing ideal emergency care. The purpose of this research was to highlight educational needs specific to nurses working in 2 emergency departments in Nairobi, Kenya. METHODS: A descriptive cross-sectional study involving emergency units of 2 of the largest referral and teaching hospitals (Aga Khan University Hospital, Nairobi, and Kenyatta National Hospital) in Nairobi, Kenya, was conducted. Data were collected by using an adapted structured, self-administered questionnaire. The data were analyzed using descriptive statistics. The skills and competencies of the participants were assessed. In addition, the educational gaps and needs of the participants around emergency care such as trauma, cardiovascular diseases, and respiratory and neurological illnesses were described. Results were presented in frequencies and percentages. RESULTS: The questionnaire response rate was 63.6% (n = 84). Most of the respondents held associate degrees in nursing (72.6%), whereas 19% had a bachelor's degree in nursing. Most respondents (84.5%) perceived themselves as being highly competent in basic skills such as performing cardiopulmonary resuscitation and assessment of body systems. Less than half of the respondents (48.8%) perceived themselves as being highly competent in intermediate skills such as assisting with endotracheal intubation. In advanced competencies, such as analyzing electrocardiograms and administering thrombolytic medications, only 16.7% perceived themselves as highly competent. CONCLUSION: The results of this study suggest there is a knowledge gap and educational needs among emergency nurses in Nairobi, Kenya. It identified injuries/trauma; cardiovascular, respiratory, and neurological disease; and other emergencies as topics of focus areas with a high need. To address these knowledge and skills needs, a future specialty training in emergency nursing is recommended and this could be achieved through continuing professional development and short courses or postgraduate-level training.

Professional image of nursing and midwifery in East Africa: an exploratory analysis.

BACKGROUND: Evidence suggests that there is a negative image of nursing and midwifery that does not promote these professions as attractive career options. Furthermore, there is a paucity of studies documenting how nursing and midwifery is perceived in East Africa and where such studies exist they are country-specific. The aim of this study was to explore views regarding the image of nursing and midwifery among nurses and midwives in three East African countries, Kenya, Tanzania and Uganda. METHODS: An exploratory descriptive cross-sectional study administered online using Survey Monkey Questionnaires assessed the views and perceptions of nurses and midwives regarding the image of nursing and midwifery professions. Descriptive statistics and Pearson's Chi square tests were used to analyse the data. The semi-structured questions were analysed using content analysis. RESULTS: A total of 551 participants took part in the study. The majority were females (61.8%), registered nurses/midwives (45.8%), and aged 30-39 years (34.2%). Most of the respondents were from Kenya (39.7%) and Uganda (32.9%). About two-thirds of the nurses and midwives in this study perceived nursing/midwifery as both trusted and respected professions and expressed having a level of control over how their image was portrayed. Conversely, the nurses and midwives were conscious that the public had mixed responses about the nursing/midwifery professions specifically, some members of the public described nurses/midwives as professionals, knowledgeable and caring, others perceived nurses/midwives to be rude, cruel, unkind, lazy, unkempt, and maids. CONCLUSION: This study offers an interesting insight about the image of nursing/midwifery in East Africa. Findings from this study will inform policy makers and educators about key concepts that affect the image of nursing and midwifery in East Africa. The findings will be used to design marketing materials to help improve the image of nursing and midwifery in the region and other African countries.

Trends in and predictors of pregnancy termination among 15-24 year-old women in Nigeria: a multi-level analysis of demographic and health surveys 2003-2018.

BACKGROUND: Three-quarters of pregnancy terminations in Africa are carried out in unsafe conditions. Unsafe abortion is the leading cause of maternal mortality among 15-24 year-old women in Sub-Saharan Africa. Greater understanding of the wider determinants of pregnancy termination in 15-24 year-olds could inform the design and development of interventions to mitigate the harm. Previous research has described the trends in and factors associated with termination of pregnancy for women of reproductive age in Nigeria. However, the wider determinants of pregnancy termination have not been ascertained, and data for all women have been aggregated which may obscure differences by age groups. Therefore, we examined the trends in and individual and contextual-level predictors of pregnancy termination among 15-24 year-old women in Nigeria. METHODS: We analysed data from the 2003, 2008, 2013 and 2018 Nigerian Demographic and Health Surveys (NDHS) comprising 45,793 women aged 15-24 years. Trends in pregnancy termination across the four survey datasets were examined using bivariate analysis. Individual and contextual predictors of pregnancy termination were analysed using a three-level binary logistic regression analysis and are reported as adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: Trends in pregnancy termination declined from 5.8% in 2003 to 4.2% in 2013 then reversed to 4.9% in 2018. The declining trend was greater for 15-24 year-old women with higher socioeconomic status. Around 17% of the total variation in pregnancy termination was attributable to community factors, and 7% to state-level factors. Of all contextual variables considered, only contraceptive prevalence (proxy for reproductive health service access by young women) at community level was significant. Living in communities with higher contraceptive prevalence increased odds of termination compared with communities with lower contraceptive prevalence (aOR = 4.2; 95% CI 2.7-6.6). At the individual-level, sexual activity before age 15 increased odds of termination (aOR = 2.3; 95% CI 1.9-2.8) compared with women who initiated sexual activity at age 18 years or older, and married women had increased odds compared with never married women (aOR = 3.0; 95% CI 2.5-3.7). CONCLUSION: Our findings highlight the importance of disaggregating data for women across the reproductive lifecourse, and indicates where tailored interventions could be targeted to address factors associated with pregnancy termination among young women in Nigeria.

Is there sufficient evidence for a causal association between antiretroviral therapy and diabetes in HIV-infected patients? A meta-analysis.

The association of antiretroviral therapy (ART) with diabetes is inconsistent and varies widely across primary epidemiological studies. A comprehensive and more precise estimate of this association is fundamental to establishing a plausible causal link between ART and diabetes. We identified epidemiological studies that compared mean fasting plasma glucose (FPG) concentrations and proportions of diabetes and metabolic syndrome between HIV-infected patients naïve and exposed to ART. Mean difference in FPG concentrations and odds ratios of diabetes and metabolic syndrome were pooled using random-effects meta-analyses. Data on 20 178 participants from 41 observational studies were included in the meta-analyses. Mean FPG concentrations (Pooled mean difference: 4.66 mg/dL; 95% confidence interval [CI], 2.52 to 6.80; 24 studies) and the odds of diabetes (Pooled odds ratios: 3.85; 95% CI, 2.93 to 5.07; 10 studies) and metabolic syndrome (Pooled odds ratios: 1.45; 95% CI, 1.03 to 2.03; 18 studies) were significantly higher among ART-exposed patients, compared to their naïve counterparts. ART was also associated with significant increases in FPG levels in studies with mean ART duration ≥18 months (Pooled mean difference: 4.97 mg/dL; 95% CI, 3.10 to 6.84; 14 studies), but not in studies with mean ART duration <18 months (Pooled mean difference: 4.40 mg/dL, 95% CI, -0.59 to 9.38; 7 studies). ART may potentially be the single most consistent determinant of diabetes in people living with HIV worldwide. However, given the preponderance of cross-sectional studies in the meta-analysis, the association between ART and diabetes cannot be interpreted as cause and effect.

Prevalence of sickle cell trait and needs assessment for uptake of sickle cell screening among secondary school students in Kampala City, Uganda.

BACKGROUND: Sickle cell disease (SCD) is one of the most frequent and traumatizing genetic disease in Uganda, with the prevalence of the sickle cell trait (SCT) estimated at 13.3% leading to serious psycho-social and economic impact on the patients and their families. AIM: This study aimed to determine the burden of SCT and factors influencing the uptake of screening services among secondary school students in Uganda. METHODS: We used an analytical cross-sectional design with a multi-stage sampling approach. A total of 399 students from four secondary schools in Kampala City were enrolled in this study. Data were gathered using semi-structured questionnaires and blood screening. We used the sickling test to determine the presence of sickle cell alleles among the participants and hemoglobin electrophoresis as a confirmatory test. Data gathered using the questionnaire were analyzed using descriptive and inferential statistics. RESULTS: In total, 5.8% of participants who were tested during this study had SCT. Most (80.2%) participants were not in an intimate relationship at the time of data collection. The majority (60.4%) had moderate knowledge about SCT screening and obtained information about screening from the school. Only 29 (7.3%) participants knew of a family member with sickle cell. Overall, participants had a negative attitude toward SCT screening (67%), although 41.6% believed that most people who were sickle cell carriers did not live long and were often sick. Statistically significant associations were found between testing for SCT and knowing a partner's sickle cell status (odds ratio [OR] 2.112, p = 0.043) and Anglican religion (OR 2.075, p = 0.047). CONCLUSION: Despite the moderate level of knowledge and negative attitudes, a relatively large number of participants had SCT. This highlights the need for a comprehensive health education package targeting adolescents to promote SCD/SCT screening.

Mental health and psychological well-being of Kenyan adolescents from Nairobi and the Coast regions in the context of COVID-19.

BACKGROUND: Despite the high burden of mental health problems during adolescence and its associated negative consequences, it has remained neglected especially in sub-Saharan Africa. The 2019 novel Coronavirus disease (COVID-19) pandemic has placed additional stress on adolescent mental health. However, there are few studies documenting the burden of mental health problems and even fewer mental health services in the region. In relation to the limited body of knowledge, the present study aims to determine the psychological well-being of adolescents and to assess the risks and associated factors of mental health problems among adolescents in the context of COVID-19 pandemic in Kenya. METHODS: We conducted a cross-sectional survey in 2022 among adolescents aged 13-19 years living in Nairobi, and the Coast region of Kenya. We utilized standardized psychological assessment tools including the Patient Health Questionnaire, Generalized Anxiety Scale, Strengths and Difficulties Questionnaire, The World Health Organization- Five Well-Being Index Scale, and the Pandemic Anxiety Scale, to evaluate the psychological wellbeing of the adolescents. A linear regression model was used to evaluate the correlates associated with quality of life, pandemic anxiety, and emotional and behavioural problems among adolescents. Subsequently, a logistic regression model was used to assess factors associated with depression and general anxiety disorders. Variables with a p-value < 0.25 in the univariate model were included in the multivariable regression model. RESULTS: The results are based on 797 participants who met the inclusion criteria. We found the prevalence of depression to be relatively higher among out-of-school adolescents at 36.0% compared to school-going adolescents at 20.6%. Furthermore, out-of-school adolescents had significantly higher anxiety scores when compared to their school-going counterparts (27.7% vs 19.1%) respectively. In-school adolescents had a better quality of life scores, lower pandemic anxiety scores, and lower emotional and behavioral problems scores compared to their out-of-school counterparts. Key risk factors associated with depression include; being out-of-school (OR = 1.96 (95% CI 1.33- 2.88) p-value = 0.001), loneliness (OR = 10.68 (95% CI 4.49-22.86) p-value < 0.001), and living in an unsafe neighborhood (OR = 2.24 (95% CI 1.52-3.29) p-value < 0.001). An older age (OR = 1.16 (95% CI 1.03-1.30) p-value = 0.015), being out-of-school (OR = 1.81 (95% CI 1.19-2.77) p-value = 0.006), and living in an unsafe neighborhood (OR = 2.01 (95% CI 1.33-3.04) p-value = 0.001 were key factors associated with anxiety. Furthermore, key factors positively correlated with quality of life include; high socioeconomic status (ß (Std.Err) = 0.58 (0.14) p-value < 0.001, talking to friends often (ß (Std.Err) = 2.32 (0.53) p-value < 0.001, and being close to parents (ß (Std.Err) = 1.37 (0.62) = 0.026. CONCLUSION: Our findings imply that mental health support services targeting adolescents in the country should be prioritized, especially for those who are out-of-school.

Factors influencing the use of multiple HIV prevention services among transport workers in a city in southwestern Uganda.

The use of multiple HIV prevention services has been found to decrease the risk of acquiring HIV when tailored to individuals at risk of HIV exposure, including transport workers. Therefore, we assessed the uptake of multiple HIV prevention services (≥2) and associated factors among transport workers in a city in Southwestern Uganda. This cross-sectional study comprised motorcycle taxi riders, motor vehicle and truck drivers, aged 18 to 55 years who were selected and responded to an interviewer-administered questionnaire, between November 2021 and February 2022. Data was analyzed using descriptive statistical and modified Poisson regression analyses. Out of 420 participants, 97.6% were male, with a median age of 28 years and the majority were aged <34 years (84.6%). Overall, less than half (45.3%) of the participants had used multiple (≥2) HIV prevention services within a one-year period. Many participants had used condoms (32.2%) followed by voluntary HIV counseling and testing (27.1%), and safe male circumcision (17.3%). Most participants who tested for HIV had ever used condoms (16.2%), followed by those who received safe male circumcision and had ever used condoms (15%), and those who tested for HIV and had started on antiretroviral therapy (ART) (9.1%). In the adjusted model, factors that were significantly associated with the use of multiple HIV prevention services included religion (aPR = 1.25, 95% CI = 1.05-1.49), the number of concurrent sex partners (aPR = 1.33, 95% CI = 1.10-1.61), prior HIV testing and awareness of HIV serostatus (aPR = 0.55, 95% CI = 0.43-0.70), awareness of HIV prevention services (aPR = 2.49, 95% CI = 1.16-5.38), and financial payment to access HIV services (aPR = 2.27, 95% CI = 1.47-3.49). In conclusion, the uptake of multiple HIV prevention services among transport workers remains suboptimal. Additionally, individual behavioral factors influence the use of multiple HIV services compared with other factors. Therefore, differentiated strategies are needed to increase the utilization of HIV prevention services among transport workers.

Capacity building among nursing and midwifery professional associations in East Africa.

BACKGROUND: Despite improvements in educational opportunities, policy changes, and pay raises in the nursing and midwifery professions in East Africa, poor working conditions, few professional development opportunities, and a general lack of respect for these professions predominate. These issues contribute to a low quality of care among a population with a high burden of communicable diseases. Health professional associations may help to address these challenges by providing a voice for nurses and midwives. OBJECTIVE: This study evaluated the impact of a 5-year programme focused on strengthening nurses' and midwives' professional associations in East Africa. METHODS: This study used a mixed methods design. Quantitative, cross-sectional descriptive data were captured via surveys (n = 1,266) distributed to association members. In-depth interviews (n = 65) were used to obtain qualitative data and complement the survey responses. Quantitative and qualitative data collection occurred concurrently. The results were compared to assess the impact of the programme across Uganda, Kenya, and Tanzania. RESULTS: The programme successfully built capacity in four of five organisational capacity areas: resource mobilisation, financial management, strategy, and monitoring and evaluation. Marketing and communications, the fifth targeted area, did not show improvement. Capacity in both research and service delivery was also improved, despite the programme not providing training in these areas. In addition, collaboration among associations and their members was improved. CONCLUSION: These results support existing evidence on the impact of capacity building among professional nursing associations and coincide with the World Health Organization's objectives for nursing. Future capacity building programmes should consider replicating the successful activities from this programme and investigate ways to reach more rural branches and provide tailored content. This study contributes to a small but growing body of knowledge that supports capacity building among the African health workforce.

Mental health interventions for adolescents in sub-Saharan Africa: A scoping review.

Background: Globally, adolescents are vulnerable to mental health problems, particularly those from sub-Saharan Africa (SSA) due to impoverished living conditions and a higher prevalence of chronic conditions such as HIV/AIDS in the region. The COVID-19 pandemic has further exacerbated this risk. This calls for an urgent need for evidence-based adolescent mental health interventions to reduce the risk and burden of mental health problems in SSA. The review aims to identify and characterize existing adolescent mental health interventions in SSA, as well as to evaluate their implementation strategies and effectiveness. Methods: We systematically searched PubMed, African Index Medicus, PsycINFO, Web of Science, and CINAHL databases for relevant articles. Furthermore, we searched gray literature databases, including Think Tank search, open gray, NGO search engine, and IGO search engine for additional relevant articles. The scoping review was conducted to identify original research articles on mental health interventions among adolescents in sub-Saharan Africa published from database inception to 31 December 2021. We carried out a narrative synthesis to report our findings. Results: Our literature search generated 4,750 studies, of which 1,141 were duplicates, 3,545 were excluded after screening, and 64 articles met the inclusion criteria. The 64 studies describe a total of 57 unique mental health interventions comprising 40,072 adolescents. The nature of these interventions was diverse, encompassing various implementation strategies such as economic-based, family strengthening, psychoeducation, interpersonal psychotherapy, Cognitive Behavioral Therapy, and resilience training, among others. Most of the interventions were selective interventions that targeted adolescents at high risk of developing mental health problems including adolescents living with HIV, war-affected adolescents, orphans, adolescents from poorer backgrounds, and survivors of sexual violence. Half of the interventions were delivered by lay persons. Sixty-two of the eligible studies examined the effectiveness of the mental health interventions, of which 55 of them reported a positive significant impact on various mental health outcomes. Conclusions: The review findings show that there exist several diverse interventions that promote mental health among adolescents in sub-Saharan Africa. These interventions can be implemented in diverse settings including schools, communities, health facilities, and camps, and can be delivered by lay persons.

Open and Distance Learning Programs for Nursing and Midwifery Education in East Africa: Protocol for a Scoping Review.

BACKGROUND: In the face of growing modernity and the coronavirus disease 2019 (COVID-19) pandemic, open and distance learning (ODL) is considered to play an important role in increasing access to education worldwide. There is a robust evidence base demonstrating its cost effectiveness in comparison with conventional class-based teaching; however, the transition to this new paradigm of learning for nursing and midwifery courses has been difficult in low-income countries. While there are notable efforts to increase internet and education access to health care professionals, not much is known about ODL for nurses and midwives in East African countries. OBJECTIVE: The objective of this scoping review is to understand whether ODL programs for nursing and midwifery education exist, the drivers of their adoption, their implementation, the topics/courses covered, their acceptability, and their impacts in East African countries. METHODS: The scoping review methodology employs the framework developed by Arksey and O'Malley. Using an exploratory approach, a two-stage screening process consisting of a title and abstract scan and a full-text review will be used to determine the eligibility of articles. To be included, articles must report on an existing ODL initiative for nurses and midwives in Uganda, Tanzania, and Kenya. All articles will be independently assessed for eligibility by pairs of reviewers, and all eligible articles will be abstracted and charted in duplicate using a standardized form. RESULTS: Details of ODL for nursing and midwifery education initiatives and study outcomes will be summarized in a table. The extracted data will undergo exploratory descriptive analysis, and the results will be classified into learner and clinical outcomes. CONCLUSIONS: Evidence on ODL for nursing and midwifery education will inform the ongoing development and restructuring of health care professional education in East Africa amidst the COVID-19 pandemic.

Prevalence of the Use of Herbal Medicines among Patients with Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Although herbal medicines are used by patients with cancer in multiple oncology care settings, the magnitude of herbal medicine use in this context remains unclear. The purpose of this review was to establish the prevalence of herbal medicine use among patients with cancer, across various geographical settings and patient characteristics (age and gender categories). METHODS: Electronic databases that were searched for data published, from January 2000 to January 2020, were Medline (PubMed), Google Scholar, Embase, and African Index Medicus. Eligible studies reporting prevalence estimates of herbal medicine use amongst cancer patients were pooled using random-effects meta-analyses. Studies were grouped by World Bank region and income groups. Subgroup and meta-regression analyses were performed to explore source of heterogeneity. RESULTS: In total, 155 studies with data for 809,065 participants (53.95% female) met the inclusion criteria. Overall, the pooled prevalence of the use of herbal medicine among patients with cancer was 22% (95% confidence interval (CI): 18%-25%), with the highest prevalence estimates for Africa (40%, 95% CI: 23%-58%) and Asia (28%, 95% CI: 21%-35%). The pooled prevalence estimate was higher across low- and middle-income countries (32%, 95% CI: 23%-42%) and lower across high-income countries (17%, 95% CI: 14%-21%). Higher pooled prevalence estimates were found for adult patients with cancer (22%, 95% CI: 19%-26%) compared with children with cancer (18%, 95% CI: 11%-27%) and for female patients (27%, 95% CI: 19%-35%) compared with males (17%, 95% CI: 1%-47%). CONCLUSION: Herbal medicine is used by a large percentage of patients with cancer use. The findings of this review highlight the need for herbal medicine to be integrated in cancer care.

Medical device-related pressure ulcers: A systematic review and meta-analysis.

OBJECTIVE: To review observational studies reporting medical device-related pressure injuries and to identify the medical devices commonly associated with pressure injuries. DESIGN: A systematic review of primary research was undertaken, according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. DATA SOURCES: A comprehensive electronic literature search of AMED, CINAHL, MEDLINE, PsycINFO, Web of Science, British Nursing Database and Google Scholar was conducted from inception to 31st December 2018. Studies that reported the prevalence or incidence of medical device-related pressure injuries and published in English language were included in the review. REVIEW METHODS: The eligibility of studies was evaluated independently by three of the four authors and audited by an independent researcher. The titles and abstracts of all studies were screened to identify studies that met the inclusion criteria. Full-text articles of the remaining studies were obtained and screened against the inclusion criteria. Risk of bias was assessed using the Newcastle-Ottawa scale. Meta-analysis was conducted using the 'metaprop' routine, with estimates of medical device-related pressure injuries from the included studies pooled using DerSimonian-Laird random-effects model. Meta-regression analysis was also conducted to examine between-study heterogeneity. RESULTS: Twenty-nine studies (17 cross-sectional studies; 12 cohort studies) comprising data on 126,150 patients were eligible for inclusion in this review. The mean ages for patients were approximately 36.2 years (adults) and 5.9 years (children). The estimated pooled incidence and prevalence of medical device-related pressure injuries were 12% (95% CI 8-18) and 10% (95% CI 6-16) respectively. These results should be interpreted with caution given the high levels of heterogeneity observed between included studies. The commonly identified medical devices associated with the risk of developing medical device-related pressure injuries include respiratory devices, cervical collars, tubing devices, splints, and intravenous catheters. CONCLUSIONS: Medical device-related pressure injuries are among key indicators of patient safety and nursing quality in healthcare facilities. This systematic review and meta-analysis provide up-to-date estimates of the extent and nature of medical device-related pressure injuries, and the findings suggest that device-related pressure injuries are a public health issue of significance, especially as these injuries affect patients' wellbeing and increase the cost of care for both patients and providers. Further research is required to inform strategies for increasing the reporting and risk assessment of medical device-related pressure injuries.

Prevalence and dynamics of missed opportunities for vaccination among children in Africa: applying systems thinking in a systematic review and meta-analysis of observational studies.

OBJECTIVE: To estimate the prevalence of missed opportunities for vaccination (MOV) among children aged 0-23 months attending health-care facilities in Africa and explore the factors responsible for MOV using systems thinking. RESEARCH DESIGN AND METHODS: We conducted a systematic review and meta-analysis of studies reporting the proportion MOVs. Five electronic databases were searched. A random effects model was fitted to obtain pooled estimates of MOV and a causal loop diagram (CLD) was constructed to explore the dynamics of the causes of MOV. MOV was defined as any contact with health services in Africa, by an unvaccinated or under-vaccinated child, aged 0-23 months, who is eligible for vaccination and free of any contraindication, which does not result in vaccination. RESULTS: Four hundred and twenty-one publications were found, of which 20 studies from 14 countries were included. The pooled prevalence of MOV was estimated to be 27.26% (95%CI: 18.80-36.62). A CLD with seven reinforcing and two balancing loops were constructed. CONCLUSION: Our findings suggest that about one in every four children under the age of two years who visited health facilities in 14 African countries missed the vaccination they were eligible to receive. To enable continent-wide estimates, more MOV assessments are required.

Impact of antiretroviral therapy on serum lipoprotein levels and dyslipidemias: a systematic review and meta-analysis.

BACKGROUND: Antiretroviral drugs increase biosynthesis and reduce hepatic clearance of serum cholesterol. It is thus important to evaluate the impact of antiretroviral treatment on serum lipoprotein levels and the risk of dyslipidemia. METHODS: We searched EMBASE and PubMed for articles comparing lipid profiles between HIV-infected adult patients naïve and exposed to antiretroviral therapy (ART). Eligible studies were pooled by performing random-effects meta-analyses of mean serum lipoprotein levels and prevalence estimates of dyslipidemias. RESULTS: 51 observational studies comprising 37,110 patients were included in the meta-analyses. ART-exposed patients had significantly higher concentrations of total cholesterol (45 studies, mean difference [MD]=29.4mg/dL, 95% confidence interval [CI] 26.5 to 32.4, I(2)=82.2%), low density lipoprotein-cholesterol (37 studies, MD=14.9mg/dL, 95% CI 11.2 to 18.5, I(2)=86.1%), and triglycerides (43 studies, MD=46.8mg/dL, 95% CI 37.8 to 55.8, I(2)=97.1%), compared with ART-naïve patients. The risks of hypercholesterolemia (25 studies, pooled odds ratio [OR] 3.8, 95% CI 3.1 to 4.7, I(2)=60.0%) and hypertriglyceridemia (21 studies, OR 2.2, 95% CI 1.7 to 2.9, I(2)=81.7%) were also significantly higher among ART-exposed patients, compared with ART-naïve patients. CONCLUSION: Antiretroviral therapy is significantly associated with increase in serum lipid levels and increased risk of dyslipidemia. Whether or not these associations are causal should be investigated by future studies.

Prevalence of Hypertension in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis.

We aimed to obtain overall and regional estimates of hypertension prevalence, and to examine the pattern of this disease condition across different socio-demographic characteristics in low-and middle-income countries. We searched electronic databases from inception to August 2015. We included population-based studies that reported hypertension prevalence using the current definition of blood pressure ≥140/90 mm Hg or self-reported use of antihypertensive medication. We used random-effects meta-analyses to pool prevalence estimates of hypertension, overall, by World Bank region and country income group. Meta-regression analyses were performed to explore sources of heterogeneity across the included studies. A total of 242 studies, comprising data on 1,494,609 adults from 45 countries, met our inclusion criteria. The overall prevalence of hypertension was 32.3% (95% confidence interval [CI] 29.4-35.3), with the Latin America and Caribbean region reporting the highest estimates (39.1%, 95% CI 33.1-45.2). Pooled prevalence estimate was also highest across upper middle income countries (37.8%, 95% CI 35.0-40.6) and lowest across low-income countries (23.1%, 95% CI 20.1-26.2). Prevalence estimates were significantly higher in the elderly (≥65 years) compared with younger adults (<65 years) overall and across the geographical regions; however, there was no significant sex-difference in hypertension prevalence (31.9% vs 30.8%, P = 0.6). Persons without formal education (49.0% vs 24.9%, P < 0.00001), overweight/obese (46.4% vs 26.3%, P < 0.00001), and urban settlers (32.7% vs 25.2%, P = 0.0005) were also more likely to be hypertensive, compared with those who were educated, normal weight, and rural settlers respectively. This study provides contemporary and up-to-date estimates that reflect the significant burden of hypertension in low- and middle-income countries, as well as evidence that hypertension remains a major public health issue across the various socio-demographic subgroups. On average, about 1 in 3 adults in the developing world is hypertensive. The findings of this study will be useful for the design of hypertension screening and treatment programmes in low- and middle-income countries.
