Associated factors of diabetic retinopathy in type 1 and 2 diabetes in Limpopo province in South Africa

Background

Diabetic retinopathy (DR) is the major cause of vision impairment or blindness in individuals who have diabetes. It has accounted for 2.6% of all cases of blindness, and 1.9% of all cases of vision impairments globally. There is a lack of data on the prevalence of diabetic retinopathy and its associated factors amongst diabetic rural populations. Hence, the current study aimed to determine factors associated with diabetic retinopathy (DR) among diabetes mellitus (DM) patients undergoing diabetic therapy.

Methods

The study was cross-sectional in design and the participants were selected using convenient sampling. STATA version 15 software was used for data analysis. Chi-square was used to compare proportions. Logistic regression was used to determine the relationship between DR and associated risk factors.

Results

The prevalence of DR was 35.3%, of which 32% were mild and 3.4% were moderate non-proliferative DR (NPDR). Females were more unemployed than males (32.1% versus 16.8%, p=0.0058). Males were found to drink alcohol (21.8% versus 1.9%, p<0.001) and smoke cigarettes (4% versus 0.3%, p=0.0034) more than females. Being aged ≥ 55 years (OR: 2.7, 95% CI: 1.6-4.4), with matric qualification (OR: 0.6; 95% CI: 0.4-1.0); employed (OR: 1.4, 95% CI: 1.2-1.6); having high systolic blood pressure (OR=1.4, 95%CI=1.1-1.7) were the independent determinants of DR.

Conclusions

The prevalence of diabetic retinopathy was 34%. DR was determined by high systolic blood pressure, old age, and employment. Although not statistically significant, gender, hyperglycemic state, poor glycemic control, smoking, and increased body mass index (BMI) were associated with increased risk of developing DR.

Determinants of central obesity in children and adolescents and associated complications in South Africa: a systematic review

Background

Central obesity in children is a global health concern associated with cardiovascular risk factors. In 2019 the World Obesity Federation predicted that in 2025, 206 million children and adolescents aged 5 to 19 will be obese, and the number is estimated to reach 254 million by 2030. There is limited literature on the factors that are associated with the development of central obesity in children. We report a systematic review, aimed to describe the current literature on determinants of central obesity and its associated health outcomes in children and adolescents in the South African population.

Methods

We searched for peer-reviewed studies in Google Scholar, PubMed, and Science Direct search engines, and about seven studies were included. This systematic review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO) (Registration number: CRD42023457012). This systematic review was conducted and reported according to an updated version of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The quality of the included studies was assessed by following guidelines from the Newcastle-Ottawa Scale (NOS). The method considered three main domains: selection, comparability, and outcome across different study designs.

Results

The prevalence of central obesity in children and adolescents by waist-to-height ratio (WHtR) ranged from 2.0 to 41.0%; waist-to-hip [WHR ranged from 10 to 25%; waist circumference (WC) ranged from 9 to 35%]. Central obesity was associated with age, physical inactivity, gender socio, and demographic profiles of the household. Central obesity in children was associated with cardiovascular diseases and mental health issues.

Conclusion

Central obesity in children and adolescents was determined by gender, pubertal development, and age of the parents, households with high socioeconomic status, dietary practices, and overweight/obesity. Given the high prevalence of central obesity in children which can ultimately result in cardiometabolic diseases, cardiovascular risk factors, and mental health issues. This highlights the need for systems, jointly initiated by healthcare providers, policymakers, and the general society aimed at reducing the burden of central obesity such as introducing children and adolescents to health-promoting lifestyles.

Exploring mental health problems and support needs among pregnant and parenting teenagers in rural areas Of Limpopo, South Africa

BACKGROUND

Globally, teenage pregnancy is among the most social problems, affecting 21 million adolescents aged 15-19. Due to the increased responsibility of prenatal and postnatal care for their infants without support, pregnant and parenting teenagers, tend to experience mental health problems. Factors contributing to these problems among pregnant and parenting teenagers in rural African settings have hardly received scholarly attention and, therefore, are less understood. The purpose of the study was to explore mental health and challenges among pregnant and parenting teenagers,.

METHOD(S)

The study adopted a qualitative descriptive, exploratory, and phenomenological design. Purposive sampling was used to select 22 pregnant and parenting teenagers 18 years or older. Data were collected in ten selected clinics within the Demographic Surveillance Systems (HDSS) of DIMAMO and analysed using qualitative content analysis.

RESULTS

The findings reveal that pregnant and parenting teenagers in rural areas experience various mental challenges such as depression. These challenges are caused by social problems such as stigmatisation, lack of support from families and friends, as well as parenting demands that contribute to poor progress at school or dropouts. Pregnant teens expressed concerns about the lack of spousal support resulting from abandoning their partners.

CONCLUSIONS

Stress and depression were self-reported as mental problems among participants with various psychosocial implications, such as school dropout and miscarriage. There are various contributing factors to the mental health problems identified among pregnant and parenting teenagers, including inadequate family and spousal support. Access to integrated reproductive, psychosocial, and mental health services could be essential for these pregnant and parenting teenagers, to improve their mental well-being and improve the support system.

The Use of Non-Prescribed Medicines in Infants from Birth to Six Months in Rural Areas of Polokwane Municipality-Limpopo Province, South Africa

The WHO and UNICEF recommend that only breastmilk, vitamin drops, oral rehydration solution, and prescribed medicine can go through the infant's mouth. Non-prescribed medications (NPM) include over-the-counter medications and traditional medicine and are contraindicated during infancy. Furthermore, the updated exclusive breastfeeding (EBF) indicator details that herbal fluids and similar traditional medicines are counted as fluids, and infants who consume these are not exclusively breastfed. However, the use of these items is common among caregivers for various reasons, including religious reasons, cultural beliefs, prevention of diseases, and the treatment of diseases. The practice of administering NPM before six months of age undermines exclusive breastfeeding and can result in undesirable health outcomes.

METHODS

The purpose of this study was to determine the prevalence of NPM, describe the types of medications used, and explain why caregivers use NMP in infants younger than six months of age. A quantitative approach and a facility-based cross-sectional survey were used to conduct this study. Convenience sampling was used to select clinics, and proportionality and simple random sampling were used to select 146 participants. Data were analyzed using SPSS (29). A p-value of p < 0.05 was considered significant.

RESULTS

In this study, the prevalence of NPM was 75.3%. Of the 146 participants, most were 25-35 years old (54%) and first-time mothers (36.3%). More caregivers had high school and matric (67.1%), and 84.2% of caregivers delivered in public health facilities. Almost three-quarters are unemployed (66.7%) and on a child support grant (56.4%). About 43.6% of infants received NPM within the first month of life. The main source of advice to give NPM was family members (86.4%). The main reasons for administering NPM were the treatment of the umbilical cord (57.3%) and the prevention of colic (32.7%). The results show a statistically significant association between the administration of medication and the age of the infant, p < 0.005.

CONCLUSIONS

Non-prescribed medications are highly prevalent in the rural areas of Polokwane and are practiced by caregivers between the ages of 25-35 years advised by the families. Access to self-medication should be controlled, especially in the first month of life. Interventions to reduce the use of NPM should be targeted at young mothers and their families.

Barriers and enablers to exclusive breastfeeding by mothers in Polokwane, South Africa

Background

Exclusive breastfeeding (EBF) for six months, with the introduction of appropriate complementary feeding thereafter, and breastfeeding continuing for up to 2 years and beyond, is highly recommended. This could save the lives of up to 1.4 million children each year worldwide. Despite this, breastfeeding rates in South Africa remain sub-optimal, with the recommended target of 50% by the World Health Assembly (WHA) not being achieved. The study aimed to investigate the reasons influencing mothers' practice of exclusive breastfeeding in the Polokwane municipality of Limpopo province in South Africa.

Methodology

A cross-sectional health facility-based quantitative and descriptive survey was conducted using a validated-structured questionnaire administered to 146 mothers. The data was analyzed using STATA. Chi-square tests were used to determine the relationship between selected demographic variables and their reasons not to breastfeed exclusively.

Results

Although 94% of the mothers had initiated breastfeeding, at the time of data collection 8% had stopped. Of those who had stopped breastfeeding, 5% did so within one month of starting. Thirty- nine percent of mothers' breastfed exclusively, while 61% practiced mixed feeding. A positive association between exclusive breastfeeding practices and the age of the mother were observed, with older mothers more likely to breastfeed. The reasons mothers stopped breastfeeding were: the mother was ill (45%) or they returned to school or work (27%). Reasons for not breastfeeding were cited as: medical conditions, not enough milk, and infant refusal to breastfeed (33%). Mothers believe that HIV-positive women should breastfeed their infants (57%), and health workers were found to be the main source of HIV information to mothers (77%).

Discussion

Exclusive breastfeeding during the first six months was less practiced. Infant formula and solid foods were introduced at an early age, usually within the first month of breastfeeding. This study sheds light on factors influencing the early initiation of breastfeeding and the practice of EBF as practiced in Polokwane.

Association of carotid intima-media thickness and dyslipidaemia in patients with type 2 diabetes: a protocol for systematic review and meta-analysis

INTRODUCTION

Patients with diabetes mellitus (DM) often present with comorbidities such as hypertension, dyslipidaemia, insulin resistance, obesity and hyperglycaemia, which increases their risk of cardiovascular diseases (CVDs)-related mortality. Carotid intima-media thickness (CIMT), a biomarker for subclinical atherosclerosis, has been associated with overall CVD, especially in type 2 DM (T2DM). Hence, this protocol for systematic review and meta-analysis aims to review existing literature on the association of CIMT and dyslipidaemia in patients with T2DM.

METHODS AND ANALYSIS

The proposed systematic review and meta-analysis will be conducted according to an updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols guideline. A comprehensive search of peer-reviewed studies on Google Scholar, PubMed, Science Direct and Web of Sciences databases will be conducted up to 30 June 2023. A meta-analysis of data extracted from selected studies will be performed to explore the association between dyslipidaemia and CIMT in patients with diabetes. The effect estimates will be reported as standardised mean differences/Cohen's d and 95% CIs. A random effect model will be used in case of high heterogeneity whereas fixed-effect model will be used in the absence of heterogeneity. All statistical analysis will be performed using SPSS V.29.0 software. In cases of high heterogeneity, subgroup analysis will be performed based on study design, countries of publication and body mass index to identify potential sources of heterogeneity. Publication bias will be assessed graphically via funnel plots and statistically using Egger's regression test. Sensitivity analysis will also be performed to evaluate the stability of the overall effect size and the grading of recommendations assessment, development and evaluation will be used to grade the quality of analysed evidence.

ETHICS AND DISSEMINATION

As the proposed study will use secondary published data, approval will not be sought from the ethics committee.

Prevalence and factors associated with anaemia among pregnant women attending antenatal care in a district hospital and its feeder community healthcare centre of the Limpopo Province, South Africa

Background

Pregnancy anaemia is a significant public health concern in South Africa (SA), particularly in rural areas, but little is known about its prevalence and risk factors in rural areas. The objective of the study was to determine the prevalence and identify risk factors of pregnancy anaemia in the public health facilities of Limpopo Province (LP), SA.

Methods

A cross-sectional study was conducted among a consecutive sample of 211 pregnant women attending antenatal care at Seshego Hospital and its feeder health centre (May to June 2019). Anaemia was defined as haemoglobin (Hb) <11 g/dL and classified as mild (10-10.9 g/dL), moderate (7-9.9 g/dL) and severe anaemia (<7 g/dL). A multiple logistic regression analysis was used to identify predictors of anaemia.

Results

The mean age of the women was 28.4 ± 5.7 years (range from 18 to 41 years). Over half (52%) had secondary education, 65% were unmarried, 72% were unemployed, 34% were nulliparous, 15% were human immunodeficiency virus (HIV) infected and 67% were in the third trimester. The anaemia prevalence was 18.0% and was significantly associated with parity, HIV status and body mass index (BMI) in a multivariate logistic regression analysis.

Conclusion

This study found that less than one-third of pregnant women were affected by anaemia, associated with parity, HIV infected and BMI. It is essential to promote routine screening for anaemia, health education and prompt treatment of infections to reduce this burden. In addition, further studies on risk factors for anaemia during pregnancy in both urban and rural communities should be conducted to strengthen these findings.

Lived experiences of students with virological failure on antiretrovirals at a university in Limpopo

BACKGROUND

 Human immunodeficiency virus (HIV)-positive students at a rural university in Limpopo province are followed-up according to the national guidelines for the treatment of HIV. Blood monitoring revealed that some students on antiretroviral (ARV) treatment were not virologically suppressed despite adherence and compliance being emphasised at every visit.

OBJECTIVES

 The study sought to identify the students' experiences that were hindering the viral load from improving.

METHOD

 A two-phase qualitative, explorative, descriptive study design was followed. Convenience purposive sampling methods were taken on. By means of a semi-structured interview guide, face-to-face interviews were directed. Thematic content analysis was applied.

RESULTS

 Non-disclosure, noisy ARV packaging, stigma, and service delivery played a role in determining levels of student adherence and compliance with ARVs in the study sample.

CONCLUSION

 Study findings suggest practical recommendations to improve compliance among students on ARVs: provision of HIV education to all students to help reduce stigma and make it easier to disclose HIV status; use of user-friendly noise-free packaging by pharmaceutical companies to enclose medication, such as blister packs; a supermarket approach in service delivery points to reduce the stigmatising effects of consulting rooms for ARV services.Contribution: There is scope to examine the relevance of these findings for other students in the country, to compare them, and to use material from larger studies to guide targeted interventions that could improve adherence among young people.

Risky sexual behaviors and associated factors among adult patients on antiretroviral treatment at Mankweng Hospital in Limpopo Province, South Africa

Background

Worldwide, it is estimated that 38 million people are HIV-positive and that over 36 million people have died from the virus. In South Africa, the prevalence of HIV was reported to be 20.6% with Limpopo Province having 17% HIV. Given the high rate of new HIV infection in Limpopo, there is therefore a need to assess factors promoting risky sexual behavior among people living with HIV in order to help design and develop behavioral interventions aimed at reducing risky behaviors among people living with HIV.

Methods

This was a quantitative cross-sectional prospective study, conducted in Mankweng Hospital. The study consisted of 116 participants of which 40 were males and 76 were females aged 18 years and above. The participants were selected using purposive sampling. The data was analyzed using Statistical Package for Social Sciences version 27. A comparison of proportions was performed using Chi-Square. The association between risky sexual practice and sociodemographic factors was analyzed using multivariate logistic regression.

Results

The proportion of risky sexual practices in the total population was 48.3%. Participants who were married, those aged 35-44, and those with tertiary qualifications were more likely to engage in risky sexual practices. Multivariate logistic regression showed widowed participants were less likely to practice risky sexual practices.

Conclusion

The present study reported a high prevalence of risky sexual practices of 48.3%. Risky sexual behavior was determined by age, marital status, and level of education. The proportion of married participants was higher in risky sexual behavior. Based on the findings of the present study, it is recommended that targeted interventions and educational programs should be implemented to reduce risky sexual behavior among married individuals, individuals aged 35-44, and individuals with tertiary qualifications.

Knowledge, attitude and preventative practice of tuberculosis in rural communities of Dikgale, Mamabolo and Mothiba health and demographic surveillance system in Limpopo province, South Africa

BACKGROUND

Tuberculosis continues to be a serious public health issue. To reduce the transmission of the disease, it is imperative to address the major obstacle of inadequate understanding regarding the causes, risk factors, treatments, and prevention of pulmonary TB. The study assessed knowledge, attitude, and preventative practices of tuberculosis among community members in Dikgale, Mamabolo and Mothiba (DIMAMO) Health Demographic Surveillance system, Limpopo Province South Africa.

METHODS

A cross-sectional clinic-based survey involving 360 participants was conducted at clinics at Dikgale, Mamabolo and Mothiba (DIMAMO) Health and Demographic Surveillance System. A standardised questionnaire on socio-demographic, knowledge, attitude and preventative practices towards tuberculosis based on (WHO) KAP-TB template guidelines was used to collect data. Descriptive statistics on Statistical Package for Social Sciences (SPSS) version 27.0 was used to analyse data.

RESULTS

The results of the cross-sectional survey on KAP-TB illustrated that the participants have good knowledge, attitude, and perception of TB. Majority of the participants (n = 270, 75%) had good general knowledge, while (n = 90, 25%) had poor knowledge about TB. However, the study reports (n = 57, 15.6%) having knowledge of causative agents of TB. Participants showed a favourable attitude toward people who are infected with TB. 87% showed a favourable attitude while only 12.46% showed an unfavourable attitude towards TB. Participants showed a good practice of (71.7%) while (28.3%) of participants had poor practice towards TB.

CONCLUSION

Health education interventions programme on TB needs to be intensified among the community members to improve TB awareness and reduce transmission. Focused educational interventions on TB aetiology and mode of transmission are required to increase TB preventative practices and improve health-seeking behaviour among community members.

Evaluation of drug-resistant tuberculosis treatment outcome in Limpopo province, South Africa

BACKGROUND

South Africa has the second-highest tuberculosis (TB) incidence globally. Drug-resistant TB (DR-TB) treatment has less successful treatment outcomes as compared with susceptible TB, and it hinders TB control and management programmes.

AIM

This study aimed to evaluate drug-resistant TB treatment outcomes and factors associated with successful treatment outcomes.

SETTING

The study was conducted in five districts in Limpopo province.

METHODS

The study design was retrospective and descriptive. Patients' demographic data, data on clinical characteristics and treatment outcomes data were extracted from the electronic drug-resistant tuberculosis register (EDRWeb) database system for the period, 2010-2018, in Limpopo province. Frequency, percentages and bivariate and multivariate logistic regression were used to analyse data using Statistical Package for Social Sciences version 27.0. The significance difference was determined at a 95% confidence interval and p 0.05.

RESULTS

A total of 385 drug-resistant records were included in this study. The treatment success rate was 223 (57.9%). A total of 197 (51.2%) patients were cured, 26 (6.8%) completed treatment, 19 (4.9%) treatment failure, 62 (16.1%) died, 78 (20.6%) were recorded as the loss to follow-up, 1 (0.3%) moved to another country and 2 (0.5%) were transferred out.

CONCLUSION

The treatment success rate was 57.9%, which is still below targets set by National Strategic Plan in South Africa and World Health Organization End TB targets.Contribution: The findings of the study reveal that to achieve successful DR-TB control programme and attain End TB targets, monitoring of treatment outcomes is crucial.

Diabetes care cascade and associated factors in 10 700 middle-aged adults in four sub-Saharan African countries: a cross-sectional study

OBJECTIVES

We investigated progression through the care cascade and associated factors for people with diabetes in sub-Saharan Africa to identify attrition stages that may be most appropriate for targeted intervention.

DESIGN

Cross-sectional study.

SETTING

Community-based study in four sub-Saharan African countries.

PARTICIPANTS

10 700 individuals, aged 40-60 years.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome measure was the diabetes cascade of care defined as the age-adjusted diabetes prevalence (self-report of diabetes, fasting plasma glucose (FPG) ≥7 mmol/L or random plasma glucose ≥11.1 mmol/L) and proportions of those who reported awareness of having diabetes, ever having received treatment for diabetes and those who achieved glycaemic control (FPG <7.2 mmol/L). Secondary outcome measures were factors associated with having diabetes and being aware of the diagnosis.

RESULTS

Diabetes prevalence was 5.5% (95% CI 4.4% to 6.5%). Approximately half of those with diabetes were aware (54%; 95% CI 50% to 58%); 73% (95% CI 67% to 79%) of aware individuals reported ever having received treatment. However, only 38% (95% CI 30% to 46%) of those ever having received treatment were adequately controlled. Increasing age (OR 1.1; 95% CI 1.0 to 1.1), urban residence (OR 2.3; 95% CI 1.6 to 3.5), hypertension (OR 1.9; 95% CI 1.5 to 2.4), family history of diabetes (OR 3.9; 95% CI 3.0 to 5.1) and measures of central adiposity were associated with higher odds of having diabetes. Increasing age (OR 1.1; 95% CI 1.0 to 1.1), semi-rural residence (OR 2.5; 95% CI 1.1 to 5.7), secondary education (OR 2.4; 95% CI 1.2 to 4.9), hypertension (OR 1.6; 95% CI 1.0 to 2.4) and known HIV positivity (OR 2.3; 95% CI 1.2 to 4.4) were associated with greater likelihood of awareness of having diabetes.

CONCLUSIONS

There is attrition at each stage of the diabetes care cascade in sub-Saharan Africa. Public health strategies should target improving diagnosis in high-risk individuals and intensifying therapy in individuals treated for diabetes.

Identifying the prevalence and correlates of multimorbidity in middle-aged men and women: a cross-sectional population-based study in four African countries

OBJECTIVES

To determine the prevalence of multimorbidity, to identify which chronic conditions cluster together and to identify factors associated with a greater risk for multimorbidity in sub-Saharan Africa (SSA).

DESIGN

Cross-sectional, multicentre, population-based study.

SETTING

Six urban and rural communities in four sub-Saharan African countries.

PARTICIPANTS

Men (n=4808) and women (n=5892) between the ages of 40 and 60 years from the AWI-Gen study.

MEASURES

Sociodemographic and anthropometric data, and multimorbidity as defined by the presence of two or more of the following conditions: HIV infection, cardiovascular disease, chronic kidney disease, asthma, diabetes, dyslipidaemia, hypertension.

RESULTS

Multimorbidity prevalence was higher in women compared with men (47.2% vs 35%), and higher in South African men and women compared with their East and West African counterparts. The most common disease combination at all sites was dyslipidaemia and hypertension, with this combination being more prevalent in South African women than any single disease (25% vs 21.6%). Age and body mass index were associated with a higher risk of multimorbidity in men and women; however, lifestyle correlates such as smoking and physical activity were different between the sexes.

CONCLUSIONS

The high prevalence of multimorbidity in middle-aged adults in SSA is of concern, with women currently at higher risk. This prevalence is expected to increase in men, as well as in the East and West African region with the ongoing epidemiological transition. Identifying common disease clusters and correlates of multimorbidity is critical to providing effective interventions.

Mental health needs among pregnant and parenting adolescent girls and young women in South Africa: A scoping review

Teenage pregnancy and parenting pose a greater risk of developing mental health problems among pregnant and parenting adolescent girls and young women. We report on a scoping review of peer-reviewed articles to identify mental health needs and challenges among pregnant and parenting adolescent girls and young women. We adopted only five steps of the Arksey and O'Malley framework to facilitate the scoping review of 125 articles published between July 2002 and August 2022 from these databases (MEDLINE, SABINET, EBSCOhost, Science Direct) using search syntax. Major themes emerged from the thematic content analysis; challenges experienced by pregnant and parenting adolescent girls and young women and the recommended interventions, factors associated with mental health in pregnant women and parenting adolescent girls and young women, and the implications of mental health problems. Mental health challenges, among others, include depression, stress and anxiety, post-traumatic stress disorders, and suicidal thoughts. Limited mental health interventions are provided to the group, including social support, parental coaching and counselling, and guidance, which translates to an imbalance between targeted mental health interventions and mental health challenges. We recommend involvement and education of the community on social support, development of digital health programs and integration of mental health services amongst schools, clinics, and community development to support pregnant and parenting adolescent girls and young women.

Exploring Roles of Stakeholders in Combating Substance Abuse in the DIMAMO Surveillance Site, South Africa

Background

The increasing prevalence of substance abuse in rural areas of Limpopo Province is a concern for most stakeholders including the families, South Africa Police Service, and social workers. Combating Substance Abuse requires the active roles of various stakeholders in the rural community, due to limited resources for prevention, treatment, and recovery.

Purpose

To report on the roles of stakeholders in tackling Substance Abuse during the awareness campaign conducted in the deep rural community of Limpopo Province, DIMAMO surveillance area.

Methods

Qualitative narrative design was adopted to explore the roles of stakeholders in combating Substance Abuse during the awareness campaign conducted in the deep rural community. The population consisted of different stakeholders who play an active role in reducing Substance Abuse. The triangulation method was used for data collection (interviews, observations, and taking field notes during presentations). Purposive sampling was used to select all the available stakeholders who actively combat substance abuse in the communities. Thematic narrative analysis was used to analyze the interviews conducted with and content presented by the stakeholders to generate the themes.

Results

The prevalence of Substance Abuse among the youth in the Dikgale community is high with a growing trend of Crystal Meth, "nyaope," and Cannabis(marijuana). The prevalence is worsened by the diverse challenges experienced by the families and stakeholders which impact the strategies targeted to combat Substance Abuse.

Conclusion

The findings indicated the need for strong collaborations among the stakeholders (including school leadership) to successfully combat Substance Abuse in rural areas. The findings demonstrated a need for a well-capacitated healthcare services with adequate rehabilitation centers and well-trained healthcare providers for combating Substance Abuse to minimize victim stigmatization.

Prevalence and Associated Risk Factors of Gestational Diabetes Mellitus in Limpopo Province, South Africa

The increasing prevalence of gestational diabetes mellitus (GDM) worldwide has been noted, and this can have an adverse impact on maternal and infant health and well-being. As developing countries are undergoing an epidemiological transition due to urbanisation, Westernised diets and a sedentary lifestyle, the prevalence of GDM in rural areas needs to be determined, and its associated risk factors understood. A cross-sectional descriptive study was carried out to investigate the prevalence and associated risk factors of GDM in the Limpopo Province, South Africa. A questionnaire adapted from the Michigan Diabetes Research and Training Centre (DCP 2.0) was used to measure the prevalence and associated risk factors of GDM. In this study, 101 pregnant women (74%) who were attending antenatal care (ANC) visits in Greater Giyani health facilities completed the questionnaire. Overall, the prevalence of GDM in Greater Giyani, Mopani district was 1.9%. Pregnant women above 30 years with secondary education, employed, obese and at a gestational age of 31–35 weeks were more likely to present with GDM. The results of the current study showed that a family history of diabetes was significantly associated with the development of GDM amongst pregnant women diagnosed with the health condition (P-value=0.018). The study recommends that awareness campaigns be conducted by health practitioners working with women in primary healthcare centres and hospitals during ANC visits, outreach clinics and consultations to educate women about the risk factors associated with GDM and its adverse outcomes. Therefore, this will enable women who are pregnant to be cognisant of this obstetric condition and take precautionary health measures to avoid modifiable risk factors. This study recommends that further research needs to be done on the development of an ideal strategy for screening gestational diabetes in a South African context.

Overweight Prevalence among Rural Adolescents by Household Head Obesity and Socio-Economic Status in Limpopo, South Africa

Background: Childhood obesity has become the most important and growing public health problem in the world. They add to public health challenges by increasing the burden of chronic non-communicable diseases. However, in spite of its importance, there is limited literature that evaluates the prevalence of obesity among rural adolescents in sub-Saharan Africa. We report the first study to present an insight into rural black overweight South African children and the physical characteristics and socio-economic status of the household head. A quantitative cross-sectional population study was conducted involving 51 selected primary villages within the DIMAMO surveillance area in the Capricorn District of Limpopo Province, South Africa. The study involved 294 adolescents, 154 girls and 140 boys, who were under the age of 18. Of these participants, 127 (43%) were within the normal weight range, and 167 (57%) were overweight. Gender made a significant difference, with more girls being overweight than boys. Adolescents who did not receive child grants and whose heads of household were 45−54 years old, poor, and overweight had a higher prevalence of obesity (p-value < 0.05). This study suggests that public health interventionists need to target both the heads of household and their children in hopes of reducing the prevalence of overweight and obese South African children. We further propose a better understanding of the causes of childhood overweight and obesity to guide policy development and implementation in rural settings.

Meta-analysis of sub-Saharan African studies provides insights into genetic architecture of lipid traits

Genetic associations for lipid traits have identified hundreds of variants with clear differences across European, Asian and African studies. Based on a sub-Saharan-African GWAS for lipid traits in the population cross-sectional AWI-Gen cohort (N = 10,603) we report a novel LDL-C association in the GATB region (P-value=1.56 × 10⁻⁸). Meta-analysis with four other African cohorts (N = 23,718) provides supporting evidence for the LDL-C association with the GATB/FHIP1A region and identifies a novel triglyceride association signal close to the FHIT gene (P-value =2.66 × 10⁻⁸). Our data enable fine-mapping of several well-known lipid-trait loci including LDLR, PMFBP1 and LPA. The transferability of signals detected in two large global studies (GLGC and PAGE) consistently improves with an increase in the size of the African replication cohort. Polygenic risk score analysis shows increased predictive accuracy for LDL-C levels with the narrowing of genetic distance between the discovery dataset and our cohort. Novel discovery is enhanced with the inclusion of African data.

Genetic associations and polygenic scores for lipid traits have low transferability to African individuals. Here, the authors perform a large sub-Sarahan African lipid GWAS and find that larger datasets and better global representation in discovery GWAS help to bridge this gap.

Indirect and direct effects of factors associated with diabetes amongst the rural black population in the Dikgale Health and Demographic Surveillance System, South Africa

Background

Diabetes is an enormous, growing clinical and public health problem, which together with hypertension contributes significantly to the high risk of cardiovascular diseases (CVDs) globally.

Aim

To examine the indirect and direct effects of risk factors simultaneously as a network of multiple pathways leading to diabetes in the rurally based adult population (aged 15+) using a household survey.

Methods

This investigation was based on a predictive model using a cross-sectional community-based study to identify the direct and indirect effects of diabetes risk factors in the Dikgale Health and Demographic Surveillance System (HDSS) consisting of 15 villages, with 7200 households and a total population of approximately 36 000. Fasting blood glucose and total cholesterol were measured using ILAB 300 with the following cut-off values: high fasting blood glucose 7 mmol/L and triglycerides 1.70 mmol/L.

Results

A total of 1407 individuals were interviewed, of whom 1281 had their blood pressure (BP) measured. The conceptual model was validated by the goodness-of-fit indexes (comparative fit index [CFI] = 1.00, Tucker Lewis index [TLI] = 1.041, root mean square error of approximation [RMSEA] = 0.001). Hypertension had the strongest direct effect of 0.0918 on diabetes, followed by age (0.0039) and high waist circumference (−0.0023). Hypertension also mediates the effects that high waist circumference (0.0005) and triglycerides (0.0060) have on diabetes status.

Conclusion

The results in this study confirm the conceptual model considered in the risk factors for diabetes and suggest that hypertension, age and high waist circumference are the key variables directly affecting the diabetes status in the South African rural black population. The direct effect of triglycerides on diabetes suggests mediation by some measured factor(s).

Protective Behaviors and Secondary Harms Resulting From Nonpharmaceutical Interventions During the COVID-19 Epidemic in South Africa: Multisite, Prospective Longitudinal Study

BACKGROUND

In March 2020, South Africa implemented strict nonpharmaceutical interventions (NPIs) to contain the spread of COVID-19. Over the subsequent 5 months, NPI policies were eased in stages according to a national strategy. COVID-19 spread throughout the country heterogeneously; the disease reached rural areas by July and case numbers peaked from July to August. A second COVID-19 wave began in late 2020. Data on the impact of NPI policies on social and economic well-being and access to health care are limited.

OBJECTIVE

We aimed to determine how rural residents in three South African provinces changed their behaviors during the first COVID-19 epidemic wave.

METHODS

The South African Population Research Infrastructure Network nodes in the Mpumalanga (Agincourt), KwaZulu-Natal, (Africa Health Research Institute) and Limpopo (Dikgale-Mamabolo-Mothiba) provinces conducted up to 14 rounds of longitudinal telephone surveys among randomly sampled households from rural and periurban surveillance populations every 2-3 weeks. Interviews included questions on the following topics: COVID-19-related knowledge and behaviors, the health and economic impacts of NPIs, and mental health. We analyzed how responses varied based on NPI stringency and household sociodemographics.

RESULTS

In total, 5120 households completed 23,095 interviews between April and December 2020. Respondents' self-reported satisfaction with their COVID-19-related knowledge and face mask use rapidly rose to 85% and 95%, respectively, by August. As selected NPIs were eased, the amount of travel increased, economic losses were reduced, and the prevalence of anxiety and depression symptoms fell. When the number of COVID-19 cases spiked at one node in July, the amount of travel dropped rapidly and the rate of missed daily medications doubled. Households where more adults received government-funded old-age pensions reported concerns about economic matters and medication access less often.

CONCLUSIONS

South Africans complied with stringent, COVID-19-related NPIs despite the threat of substantial social, economic, and health repercussions. Government-supported social welfare programs appeared to buffer interruptions in income and health care access during local outbreaks. Epidemic control policies must be balanced against the broader well-being of people in resource-limited settings and designed with parallel support systems when such policies threaten peoples' income and access to basic services.

Protective behaviours and secondary harms from non-pharmaceutical interventions during the COVID-19 epidemic in South Africa: a multisite prospective longitudinal study

Background:

In March 2020 South Africa implemented strict non-pharmaceutical interventions (NPIs) to contain Covid-19. Over the subsequent five months NPIs were eased in stages according to national strategy. Covid-19 spread throughout the country heterogeneously, reaching rural areas by July and peaking in July-August. Data on the impact of NPI policies on social and economic wellbeing and access to healthcare is limited. We therefore analysed how rural residents of three South African provinces changed their behaviour during the first epidemic wave.

Methods:

The South African Population Research Infrastructure Network (SAPRIN) nodes in Mpumalanga (Agincourt), KwaZulu-Natal (AHRI) and Limpopo (DIMAMO) provinces conducted longitudinal telephone surveys among randomly sampled households from rural and peri-urban surveillance populations every 2-3 weeks. Interviews included questions on: Covid-19 knowledge and behaviours; health and economic impact of NPIs; and mental health.

Results:

2262 households completed 10,966 interviews between April and August 2020. By August, self-reported satisfaction with Covid-19 knowledge had risen from 48% to 85% and facemask use to over 95%. As selected NPIs were eased mobility increased, and economic losses and anxiety and depression symptoms fell. When Covid-19 cases spiked at one node in July, movement dropped rapidly, and missed daily medication rates doubled. Economic concerns and mental health symptoms were lower in households receiving a greater number of government-funded old-age pensions.

Conclusions:

South Africans reported complying with stringent Covid-19 NPIs despite the threat of substantial social, economic and health repercussions. Government-supported social welfare programmes appeared to buffer interruptions in income and healthcare access during local outbreaks. Epidemic control policies must be balanced against impacts on wellbeing in resource-limited settings and designed with parallel support systems where they threaten income and basic service access.

Abnormal cervical cytology amongst women infected with human immunodeficiency virus in Limpopo province, South Africa

Background

Cervical cancer remains the major public problem worldwide and the most common gynaecological malignancy in the developing world, particularly in sub-Saharan Africa.

Aim

To determine the prevalence of abnormal cervical cytology amongst women with and without human immunodeficiency virus (HIV) and examine the association between HIV and histological grading.

Setting

The study was conducted in Limpopo province, which is the northernmost province of South Africa. The province has five district municipalities with one tertiary, five regional and thirty four district hospitals.

Methods

We retrospectively reviewed cervical cancer cases in Limpopo province (LP) of South Africa, using data collected routinely by the National Health Laboratory Services (NHLS). The data on smears submitted for cytology between 2013 and 2015 were extracted from the Central Data Warehouse (CDW) database.

Results

A total of 84 466 women were screened for cervical cytology smears. Their mean age was 39.8 ± 13.6 years, with range from 15 to 113 years; 77.2% were in the age group 30 years and older and 19.6% had an abnormal cervical cytology result. Overall, 46.4% of the women screened for cervical cancer were HIV infected. A significantly higher proportion of HIV-positive women had abnormal cytology than HIV-negative women (31.8% vs. 9.2%).

Conclusion

The prevalence of abnormal cytology amongst HIV-positive women is relatively high, and the risk appears to be significantly greater in all age groups. This finding highlights the need to ascertain HIV status of all women presenting with cervical cancer.

The prevalence of selected non-communicable disease risk factors among HIV patients on anti-retroviral therapy in Bushbuckridge sub-district, Mpumalanga province

Background

The rates of non-communicable diseases (NCD’s) appear to be increasing in human immunodeficiency virus (HIV) infected people as compared to non-HIV infected people and this will have major implications for clinical care. The aim of the current study was to profile selected cardiovascular disease risk factors among HIV patients on anti-retroviral therapy (ART) in Bushbuckridge sub-district.

Methods

The current study followed a quantitative cross-sectional study design using a questionnaire which was adapted from World Health Organization STEPwise approach to Surveillance (WHO STEPS). Participants were HIV infected people on ART and data was entered into a computer software Microsoft excel, then imported to Stata 12 for analysis.

Discussion

The overall prevalence of overweight at the initiation of ART amongst the participants was 18.1% and obesity was 11.5% as compared to the time of the study which was 21.4% overweight and 19.6% obese. The average time of ART initiation to study period was 3.6 years. The study findings revealed a significant difference (p-value 0.006) between the baseline and current body mass index at time of study for females. Hypertension was found to be having a significant difference (p-value 0.026 and 0.038) between the baseline and current body mass index at time of study for males and females respectively. The overall prevalence of hypertension was found to be 34.6%, overweight was 21.4% obesity was 19.6%.

The overall prevalence of abnormal waist circumference was 31.9% and females had a higher prevalence of 42.5% as compared to 4.4% of males. The overall prevalence of smoking 10.8% and alcohol consumption was 21.7%. Males were 22.5 times more likely to be smokers than females (p < 0.001) and older people were found to be 0.3 times less likely to consume alcohol as compared to young people.

Conclusions

The high levels of selected risk factors for NCDs among adults on ART in the current study area suggest an urgent need for health interventions to control risk factors in an era of HIV with an aim of reducing multiple morbidity of chronic diseases. Occurrence of NCDs and their risk factors with an aim to achieve positive effects of the long-term ART.

Interventions for improving management of chronic non-communicable diseases in Dikgale, a rural area in Limpopo Province, South Africa

Background

Chronic disease management (CDM) is an approach to health care that keeps people as healthy as possible through the prevention, early detection and management of chronic diseases. The aim of this study was to develop interventions to improve management of chronic diseases in the form of an integrated, evidence-based chronic disease management model in Dikgale, a rural area of Limpopo Province in South Africa.

Methods

A multifaceted intervention, called ‘quality circles’ (QCs) was developed to improve the quality and the management of chronic diseases in the Dikgale Health and Demographic Surveillance System (HDSS). These QCs used the findings from previous studies which formed part of the larger project in the study area, namely, the quantitative study using STEPwise survey and qualitative studies using focus group discussions and semi-structured interviews.

Results

The findings from previous studies in Dikgale HDSS revealed that an epidemiological transition is occurring. Again, the most widely reported barriers from previous studies in this rural area were: lack of knowledge of NCDs; shortages of medication and shortages of nurses in the clinics, which results in patients having long waiting-time at clinics. Lack of training of health care providers on the management of chronic diseases and the lack of supervision by the district and provincial health managers, together with poor dissemination of guidelines, were contributing factors to the lack of knowledge of non-communicable diseases (NCDs) management among nurses and community health care workers (CHWs). Consideration of all of these findings led to the development of model which focuses on integrating nursing services, CHWs and traditional health practitioners (THPs), including a well-established clinical information system for health care providers. A novel aspect of the model is the inclusion of community ambassadors who are on treatment for NCDs and are, thus, repositories of knowledge who can serve as a bridge between health care workers and community members.

Conclusion

The model developed highlights the need for health interventions that aim to control risk factors at the population level, the need for availability of NCD-trained nurses, functional equipment and medication and a need to improve the link with traditional healers.

The Prevalence and Determinants of Chronic Non-Communicable Disease Risk Factors amongst Adults in the Dikgale Health Demographic and Surveillance System (HDSS) Site, Limpopo Province of South Africa

BACKGROUND

The aim of the study was to determine the prevalence and determinants of chronic non-communicable disease (NCD) risk factors in a rural community in the Limpopo Province of South Africa.

METHODS

This survey was conducted using the WHO "STEPwise approach to the surveillance of non-communicable diseases" (STEPS) methodology. Participants were residents of the Dikgale HDSS site and standardised international protocols were used to measure behavioural risk factors (smoking, alcohol consumption, fruit and vegetable intake and, physical activity) and physical characteristics (weight, height, waist and hip circumferences and blood pressure-BP). Fasting blood glucose, triglyceride, cholesterol and HDL-C were determined in 732 participants. Data were analysed using STATA 12 for Windows.

RESULTS

The prevalence of current smokers amongst the participants was 13.7%, of which 81.3% were daily smokers. Alcohol was consumed by 16.3% of the participants. The majority of participants (88.6%) had low daily intake of fruit and vegetables and low physical activity (66.5%). The prevalence of hypertension amongst the participants was 38.2%. Overweight, obesity and high waist circumference were prevalent in females. The cardio-metabolic risk profile was not significantly different between men and women. People who were older than 40 years, overweight or obese and those who consumed alcohol were more likely to be hypertensive. Smoking was associated significantly with older age, males, never married and divorced people. Alcohol consumption was associated with older age, males, low educational status and low income.

CONCLUSION

High levels of risk factors for NCDs among adults in the Dikgale HDSS suggest an urgent need for health interventions to control these risk factors at the population level in order to reduce the prevalence of NCDs.

Ketolide agents HMR 3004 and HMR 3647 (telithromycin) inhibit the growth of Plasmodium falciparum in vitro

BACKGROUND

Malaria is on the increase due to emergence of parasite drug resistance and there is thus an urgent need for the development of new antiparasitic drugs effective at low concentrations. Ketolides antibiotics are used for treatment of various ailments and are relevant candidates to establish antiparasitic activity.

OBJECTIVES

The present study investigates the activity of ketolide compounds HMR 3004 and HMR 3647 (telithromycin) (0.025-12.5 µM) for activity against chloroquine-sensitive and resistant strains of Plasmodium falciparum in vitro.

METHODS

The antiplasmodial activity of the two ketolide agents were determined using microscopic and colorimetric [lactate dehydrogenase assay] procedures.

RESULTS

Both HMR 3004 and HMR 3647 caused a dose-dependent inhibition of growth of both parasite strains with IC50 values 3 and 15 nM, respectively. Suppression of parasite growth was evident after 8 hours of exposure to both agents at 12.5 µM with total parasite clearance achieved at 40 hours.

CONCLUSION

The results indicate lack of cross-resistance between the ketolide compounds and chloroquine, implying presence of a drug target different from that of chloroquine. The particular drug target has still to be investigated but the stage-specific results indicate that it is expressed in all parasite growth phases. These observations demonstrate the anti-malarial potential of the ketolide antimicrobial agents.

Prevalence and associated risk factors of hypertension amongst adults in a rural community of Limpopo Province, South Africa

Background

Hypertension is problem already faced by urban populations of South Africa, but little is known about its prevalence and risk factors in rural areas.

Aim

To assess the prevalence of and risk factors associated with hypertension amongst adults in a rural community in South Africa.

Setting

Dikgale Health and Demographic Surveillance Site, Limpopo Province, South Africa.

Methods

A community-based cross-sectional survey was carried out at this site where individuals aged 15 years and older were screened using a locally adapted version of the World Health Organization STEPwise questionnaire. Demographics, anthropometry and three independent blood pressure (BP) readings were taken. The average of the three BP measurements was used in analysis, and hypertension taken as systolic and diastolic BP of ≥ 140 or ≥ 90 mmHg respectively, or at least a two-week history of antihypertensive treatment. Analysis included the Chi-square test and statistical significance was set at p ≤ 0.05.

Results

A total of 1407 individuals were interviewed, of whom 1281 had complete BP, weight and height measurements taken. The mean age of participants was 44.2 ± 20.9 years(range 15–98 years), 63% were female, 55% were single and 90% were unemployed, whilst 13% were tobacco smokers and 20% reported drinking alcohol. Overall prevalence of hypertension was 41% and this was significantly associated with age and marital status.

Conclusion

The prevalence of hypertension was found to be high. Prevention strategies are urgently needed to address this life-threatening and important risk factor for cardiovascular disease in rural Limpopo Province.

Towards the elimination of malaria in South Africa: a review of surveillance data in Mutale Municipality, Limpopo Province, 2005 to 2010

BACKGROUND

South Africa has targeted to eliminate malaria by the year 2018. Constant monitoring of malaria morbidity and mortality trends in affected subpopulations is therefore crucial in guiding and refining control interventions. Mutale Municipality in Limpopo Province is one of the areas with the highest risk of malaria in the country. This paper describes trends in malaria incidence, case fatality and household indoor residual spraying (IRS) coverage in Mutale Municipality, during the period 2005 to 2010.

METHODS

A retrospective descriptive analysis was conducted on malaria data routinely collected through the Limpopo provincial malaria information system between July 2005 and June 2010. Five malaria seasons were defined. Annualized malaria incidence rates, case fatality rates (CFR) and IRS coverage rates were calculated.

RESULTS

Cumulatively, 4,663 malaria cases and 21 malaria deaths were reported in Mutale between July 2005 and June 2010. Investigation of likely origin of the malaria in 3,517 patients revealed that 6.6% were imported cases, mostly from neighbouring Zimbabwe (222/231). Malaria incidence rates fell from 13.6 cases per 1,000 person-years in the 2005-2006 season to 2.7 cases per 1,000 person-years in the 2009-2010 season. The mean malaria CFR was stable between 0.3 and 0.6% during the first four seasons, and increased sharply to 2.1% in the 2009-2010 season. The median age of the 21 malaria deaths was 34 years (range: 16 to 60 years). CFRs were 0% in children below 15 years and above 0.5% in patients more than 24 years old. Regular IRS achieved coverage above 80% in all five seasons.

CONCLUSION

Malaria control interventions implemented in Mutale significantly reduced the incidence of malaria in the population. In order to accurately monitor progress towards the elimination goal, the malaria control programme should strengthen the reporting and capturing of the data in the provincial malaria information system; all patients diagnosed with malaria should be investigated to determine the likely source of the malaria, and malaria related deaths should be audited to improve case detection and management. Furthermore, the country should strengthen cross border malaria control collaborations in order to minimize malaria importation.
