Item The socio-economic impact on health behaviour regarding blood pressure management amongst young adults(2024) Mhlaba, MimiHypertension (HTN) is a leading cause of cardiovascular disease (CVD), with hypertension prevalence among young adults (YAs) increasing on a global as well as local scale. In South Africa between 1998 and 2016, Hypertension (HTN) rates in YAs (age 15-34 years) have more than doubled. Research reports that the increasing prevalence of HTN in YAs is largely attributed to unhealthy behaviours, such as unhealthy diet, physical inactivity, smoking, drinking alcohol, and poor sleep, with YAs also perceiving themselves as invulnerable to developing HTN at a young age. Formative research has shown that lack of education, employment, and training (NEET status) presents a significant barrier to healthier behaviours in YAs. Currently, 44.7% of South African youth are NEET, indicating the increased risk of pro-HTN behaviour in this group and the need for urgent intervention. While many learnerships addressing NEET rates in the country have been implemented, few are focused on health. Therefore, this study aimed to investigate if transitioning from a NEET status to employment and health education training changes perceptions of HTN risk and health behaviour intentions. METHODS We conducted six focus group discussions (FGDs) comparing HTN-related beliefs and intention for behaviour change between NEET youth (n=20; not in employment, education, or training) and previously NEET youth on a health employment and education training initiative (HETI); n=20). All FGDs were approximately 70 minutes in duration and were recorded and transcribed verbatim. The study utilised the conceptual framework of the Health Belief Model (HBM) to inform the FGD topic guide and a deductive thematic analysis. Frequent debriefing and review sessions with research supervisors were conducted to ensure the quality of the analysis. RESULTS All youth were familiar with HTN but for NEET youth, who only knew it as “high-high” or “high blood”, this was mostly through experiences of others in their social network. While all youth viewed HTN as life-threatening if left untreated and expressed fear of lifelong medication use if diagnosed, only HETI youth felt empowered to implement positive health behaviours for disease prevention. Intention for behaviour change was related to personal relevance resulting from the practical application of HTN knowledge in their daily lives. In contrast, NEET youth felt chronic disease was inevitable at an older age and demonstrated no intention for behaviour change. Past negative experiences in local clinics and the fear of distress in the event of a possible diagnosis were described as major deterrents to blood pressure (BP) screening. CONCLUSION Results suggest that engaging NEET (Not in employment, education, or training) youth in similar HETI (Health employment and education training initiative) programs can increase personal relevance of health information, which serves as a motivator to increase intentions toward healthier behaviours for chronic disease prevention. This may also result in double-duty benefits, reducing a NEET status as well as the risk for chronic illness among the YA population.Item Sexual history taking: doctors’ clinical decision-making in primary care in the North West province, South Africa(AOSIS, 2021-09-29) Pretorius, Deidre; Couper, Ian D; Mlambo, Motlatso G.Background: Clinical reasoning is an important aspect of making a diagnosis for providing patient care. Sexual dysfunction can be as a result of cardiovascular or neurological complications of patients with chronic illness, and if a patient does not raise a sexual challenge, then the doctor should know that there is a possibility that one exists and enquire. Aim: The aim of this research study was to assess doctors’ clinical decision-making process with regards to the risk of sexual dysfunction and management of patients with chronic illness in primary care facilities of the North West province based on two hypothetical patient scenarios. Setting: This research study was carried out in 10 primary care facilities in Dr Kenneth Kaunda health district, North West province, a rural health district. Methods: This vignette study using two hypothetical patient scenarios formed part of a broader grounded theory study to determine whether sexual dysfunction as comorbidity formed part of the doctors’ clinical reasoning and decision-making. After coding the answers, quantitative content analysis was performed. The questions and answers were then compared with standard answers of a reference group. Results: One of the doctors (5%) considered sexual dysfunction, but failed to follow through without considering further exploration, investigations or management. For the scenario of a female patient with diabetes, the reference group considered cervical health questions (p = 0.001) and compliance questions (p = 0.004) as standard enquiries, which the doctors from the North West province failed to consider. For the scenario of a male patient with hypertension and an ex-smoker, the reference group differed significantly by expecting screening for mental health and vision (both p = 0.001), as well as for HIV (p < 0.001). The participating doctors did not meet the expectations of the reference group. Conclusion: Good clinical reasoning and decision-making are not only based on knowledge, intuition and experience but also based on an awareness of human well-being as complex and multidimensional, to include sexual well-being.Item Neglected sexual dysfunction symptoms amongst chronic patients during routine consultations in rural clinics in the North West province(AOSIS, 2021-04-28) Pretorius, Deidre; Couper, Ian D; Mlambo, Motlatso G.Background: Sexual dysfunction contributes to personal feelings of loss and despair and being a cause of exacerbated interpersonal conflict. Erectile dysfunction is also an early biomarker of cardiovascular disease. As doctors hardly ever ask about this problem, it is unknown how many patients presenting for routine consultations in primary care suffer from symptoms of sexual dysfunction. Aim: To develop an understanding of sexual history taking events, this study aimed to assess the proportion of patients living with symptoms of sexual dysfunction that could have been elicited or addressed during routine chronic illness consultations. Setting: The research was carried out in 10 primary care facilities in Dr Kenneth Kaunda Health District, the North West province, South Africa. This rural area is known for farming and mining activities. Methods: This study contributed to a broader research project with a focus on sexual history taking during a routine consultation. A sample of 151 consultations involving patients with chronic illnesses were selected to observe sexual history taking events. In this study, the patients involved in these consultations completed demographic and sexual dysfunction questionnaires (FSFI and IIEF) to establish the proportions of patients with sexual dysfunction symptoms. Results: A total of 81 women (78%) and 46 men (98%) were sexually active. A total of 91% of the women reported sexual dysfunction symptoms, whilst 98% of men had erectile dysfunction symptoms. The youngest patients to experience sexual dysfunction were a 19-year-old woman and a 26-year-old man. Patients expressed trust in their doctors and 91% of patients did not consider discussion of sexual matters with their doctors as too sensitive. Conclusion: Clinical guidelines, especially for chronic illness care, must include screening for sexual dysfunction as an essential element in the consultation. Clinical care of patients living with chronic disease cannot ignore sexual well-being, given the frequency of problems. A referral to a sexual medicine specialist, psychologist or social worker can address consequences of sexual dysfunction and improve relationships.Item Making the case for an obstetric medicine subspecialty in South Africa(Health & Medical Publishing Group, 2020-11) Zamparini, J; Wium, LObstetric medicine is a subspecialty of internal medicine that involves the management of medical conditions that may affect the course of pregnancy. It is an established subspecialty in many parts of the world, with recognised training programmes and an active international society; however, no formal training programme has been developed in South Africa (SA) as yet. Medical problems are responsible for the majority (60%) of maternal deaths in SA and women of childbearing potential are disproportionately affected by medical conditions such as HIV and obesity. Obstetric physicians would play a complementary role in the care of pregnant patients and could contribute to improving maternal health and lowering the maternal mortality rate in SA
