BACKGROUND: Multiple risk factors can contribute to the development of coronary heart disease (CHD) in an individual, yet any change in the modifiable CHD risk status of Black South African females in recent times is unknown.AIM: The researcher aimed to establish the current CHD risk status of urban Black African females and to report on any trends over a 10-year period with the purpose to direct health promotion programs.METHODS: Data from 62 urban Black females (Mean age 32.4 ± 8.5 years) in 2006 was paired for age with that of 67 women (Mean age 32.0 ± 9.0 years) in 2016. The modifiable CHD risk factors assessed were cigarette smoking, sedentary lifestyle, obesity, hypertension, and hypercholesterolemia.RESULTS: Physical inactivity (72.6% of the sample in 2006 vs. 75.8% in 2016) and obesity (42% in 2006 vs. 38.8% in 2016) were the top-ranked risk factors for CHD with the pattern unchanged in 2016. Significantly fewer participants (4.5% vs. 16.6%; p < 0.05) were hypertensive and significantly more women had hypercholesterolemia (5.6% vs. 23.9%; p < 0.05) in 2016. The multiple CHD risk profile showed that 42.4% had at least one CHD risk factor (an increase of 25%) and significantly fewer (27.3% vs. 45.2%; p < 0.05) had two CHD risk factors in 2016.CONCLUSION: A sedentary lifestyle and obesity were the highest CHD risk factors. Also, the multiple CHD risk profile of Black African women changed over a period of 10 years from higher to lower and normal risk. Health promotion strategies must be directed towards weight reduction, increasing physical activity levels and be tailored for the population for which the health promotion programs have been designed.

Background and Purpose:The purpose of this study was to assess the relationships between an individual’s characteristics and experiences (age, gender, level of education, income, and employment), knowledge of coronary heart disease (CHD) risk factors, perception of health status, awareness of CHD, and health promotion behaviors among adult Omanis.Methods:Using Pender’s health promotion model, a cross-sectional and correlational survey design was employed. A self-administered questionnaire was distributed to 180 participants in Muscat, the capital of Oman. Descriptive and multivariate linear regression analyses were employed.Results:Increasing age was associated with high levels of awareness about CHD. Participants who were employed and knowledgeable about CHD risk factors were more likely to have lower perceptions of health. The regression model showed that knowledge of CHD risk factors and awareness of CHD had positive associations with health promotion behaviors. Meanwhile, employed participants had lower health promotion behaviors scores.Implications for Practice:Interventions to increase health promotion behaviors should include application of behavioral change strategies that are suitable for age and employment status. The strategies must focus on providing information to enhance knowledge and awareness about CHD.

Chd Risk Factors

Cardiovascular disease, and particularly coronary heart disease (CHD), has a low incidence in premenopausal women. Loss of ovarian hormones during the perimenopause and menopause leads to a sharp increase in incidence. Although most CHD risk factors are common to both men and women, the menopause is a unique additional risk factor for women. Sex steroids have profound effects on many CHD risk factors. Their loss leads to adverse changes in lipids and lipoproteins, with increases being seen in low density lipoprotein (LDL) cholesterol and triglycerides, and decreases in high density lipoprotein (HDL) cholesterol. There is a reduction in insulin secretion and elimination, but increases in insulin resistance eventually result in increasing circulating insulin levels. There are changes in body fat distribution with accumulation in central and visceral fat which links to the other adverse metabolic changes. There is an increase in the incidence of hypertension and of type 2 diabetes mellitus, both major risk factors for CHD. Oestrogens have potent effects on blood vessels and their loss leads to dysfunction of the vascular endothelium. All of these changes result from loss of ovarian function contributing to the increased development of CHD. Risk factor assessment in perimenopausal women is recommended, thereby permitting the timely introduction of lifestyle, hormonal and therapeutic interventions to modify or reverse these adverse changes.

AbstractPhysiological studies of elite and sub-elite black South African runners show that these athletes are typically about 10–12 kg lighter than white athletes and that they are able to sustain higher exercise intensities for longer than white runners. Such superior performance is not a result of higher V O2max values and hence cannot be due to superior oxygen delivery to the active muscles during maximal exercise, as is predicted by the traditional cardiovascular/anaerobic/catastrophic models of exercise physiology. A marginally superior running economy is also unlikely to be a crucial determinant in explaining this apparent superiority. However, black athletes are able to sustain lower rectal and thigh, but higher mean skin, temperatures during exercise. Furthermore, when exercising in the heat, lighter black athletes are able to maintain higher running speeds than are larger white runners matched for running performance in cool environmental conditions. According to the contrasting theory that the body acts as a complex system during exercise, the superiority of black African athletes should be sought in an enhanced capacity to maintain homeostasis in all their inter-dependent biological systems despite running at higher relative exercise intensities and metabolic rates. In this case, any explanation for the success of East African runners will be found in the way in which their innate physiology, training, environment, expectations and genes influence the function of those parts of their subconscious (and conscious) brains that appear to regulate the protection of homeostasis during exercise as part of an integrative, complex biological system.

The Impact

Objective: The aim of this study is to examine the prevalence of coronary heart disease (CHD)–related disability (hereafter also “disability”) and the impact of CHD risk factors on disability in older adults in the Republic of Ireland (ROI) and Northern Ireland (NI). Method: Population attributable fractions were calculated using risk factor relative risks and disability prevalence derived from The Irish Longitudinal Study on Ageing and the Northern Ireland Health Survey. Results: Disability was significantly lower in ROI (4.1% vs. 8.8%). Smoking and diabetes prevalence rates, and the fraction of disability that could be attributed to smoking (ROI: 6.6%; NI: 6.1%), obesity (ROI: 13.8%; NI: 11.3%), and diabetes (ROI: 6.2%; NI: 7.2%), were comparable in both countries. Physical inactivity (31.3% vs. 54.8%) and depression (10.2% vs. 17.6%) were lower in ROI. Disability attributable to depression (ROI: 16.3%; NI: 25.2%) and physical inactivity (ROI: 27.5%; NI: 39.9%) was lower in ROI. Discussion: Country-specific similarities and differences in the prevalence of disability and associated risk factors will inform public health and social care policy in both countries.

Background: Prior studies of metabolomic profiles and coronary heart disease (CHD) have been limited by relatively small case numbers and scant data in women. Methods: The discovery set examined 371 metabolites in 400 confirmed, incident CHD cases and 400 controls (frequency matched on age, race/ethnicity, hysterectomy status and time of enrollment) in the Women’s Health Initiative Observational Study (WHI-OS). All selected metabolites were validated in a separate set of 394 cases and 397 matched controls drawn from the placebo arms of the WHI Hormone Therapy trials and the WHI-OS. Discovery used 4 methods: false-discovery rate (FDR) adjusted logistic regression for individual metabolites, permutation corrected least absolute shrinkage and selection operator (LASSO) algorithms, sparse partial least squares discriminant analysis (PLS-DA) algorithms, and random forest algorithms. Each method was performed with matching factors only and with matching plus both medication use (aspirin, statins, anti-diabetics and anti-hypertensives) and traditional CHD risk factors (smoking, systolic blood pressure, diabetes, total and HDL cholesterol). Replication in the validation set was defined as a logistic regression coefficient of p<0.05 for the metabolites selected by 3 or 4 methods (tier 1), or a FDR adjusted p<0.05 for metabolites selected by only 1 or 2 methods (tier 2). Results: Sixty-seven metabolites were selected in the discovery data set (30 tier 1 and 37 tier 2). Twenty-six successfully replicated in the validation data set (21 tier 1 and 5 tier 2), with 25 significant with adjusting for matching factors only and 11 significant after additionally adjusting for medications and CHD risk factors. Validated metabolites included amino acids, sugars, nucleosides, eicosanoids, plasmologens, polyunsaturated phospholipids and highly saturated triglycerides. These include novel metabolites as well as metabolites such as glutamate/glutamine, which have been shown in other populations. Conclusions: Multiple metabolites in important physiological pathways with robust associations for risk of CHD in women were identified and replicated. These results may offer insights into biological mechanisms of CHD as well as identify potential markers of risk.
