“…This highlights the urgency to address hypertension in low‐ and middle‐income countries where awareness, treatment, and control are poor . In agreement with our previous results, Lloyd‐Sherlock and colleagues indicate that excessive alcohol use is a particularly important health behavior relating directly to the development of hypertension in low‐ and middle‐income countries. Although proactive public health interventions at a population level are advocated to curb the hypertension epidemic, we need to understand why certain health behaviors, such as excessive alcohol use, are driving the hypertension epidemic.…”

2Alarming increases in the incidence of hypertension in many low-and middle-income countries are related to alcohol overuse. It is unclear whether alcohol overuse is a symptom of psychological distress. The authors assessed psychological distress in Africans and its relationship with a 5-year change in blood pressure (BP), independent of alcohol intake. The authors followed 107 Africans with optimal BP (≤120/80 mm Hg) (aged 35-75 years) over 5 years. Alcohol intake (self-report and serum c-glutamyl transferase) and nonspecific psychological distress (Kessler Screening Scale for Psychological Distress [K6]) were assessed. The K6 predicted hypertension development (P=.019), and its individual component "nervous" increased a participant's risk two-fold to become hypertensive (hazard ratio, 2.00 [1.23-3.26]). By entering K6 and c-glutamyl transferase into multivariable-adjusted regression models for change in systolic BP, both were independently associated with change in systolic BP. Psychological distress and scoring high on being nervous predicted the development of hypertension over 5 years, independent of alcohol intake.

“…We and others have demonstrated that alcohol intake (self‐report or γ‐glutamyl transferase) predicts hypertension development in black South Africans with low socioeconomic status. Furthermore, the average consumption per drinker in sub‐Saharan Africa (19.5 L) is among the highest in the world .…”

“…[34] Also similar to the previous literature, infrequent/moderate alcohol consumption was negatively associated with SBP and DBP[36], while more frequent alcohol consumption was positively associated with SBP and DBP. [37] These associations, while statistically significant, were relatively small when compared to the observed associations between age, cohort, and urbanicity with SBP and DBP. Lastly, in our sensitivity analysis, we found that BMI was positively associated with absolute SBP and DBP in men and women.…”

Objective Little is known about whether large-scale environmental changes, such as those seen with urbanization, are differentially associated with systolic versus diastolic blood pressure, and whether those changes vary by birth cohort. Methods We used data from the China Health and Nutrition Survey, a population-based cohort study of Chinese adults (n=18,976; ages 18–70y) seen a maximum of 7 times over 1991–2009. We used hierarchical multivariable linear models to simultaneously estimate systolic and diastolic blood pressure as correlated outcomes over time, accounting for their physiologic, time-varying correlation. Main exposure variables were urbanicity, age, and birth cohort. Over 18 years of modernization, median systolic and diastolic blood pressure increased by 10 and 7 mm Hg, respectively. Results Our hierarchical model results suggest greater temporal increases in systolic and particularly diastolic blood pressure at lower versus higher urbanicity. At the same chronological age, for a 10-year difference in birth cohort (i.e., born in 1980s versus 1970s) the adjusted mean diastolic blood pressure was ~3mm Hg higher for the later birth cohort (p<0.001). Pulse pressure (calculated as model-predicted systolic minus diastolic blood pressure) was also higher at low versus high urbanicity. Conclusions These results suggest increased susceptibility of diastolic blood pressure (and thus peripheral vascular resistance) to environmental change, particularly in younger Chinese adults. Because diastolic blood pressure more strongly predicts cardiovascular disease risk in younger adulthood, hypertension-related health burden in China may increase over time.

“…Although more investigations are needed, the contribution of lifestyle factors to the epidemic of hypertension in SSA is increasingly being clarified . Indeed, it is known that at least 27.5% of the population in Africa is physically inactive; more than 30% of adults are overweight or obese; and alcohol consumption adversely influences the BP levels of African populations . Although studies on sodium and potassium content of local foods are scarce in SSA, the few available findings have suggested the potentially important role of these factors in SSA .…”

Higher-than-optimal blood pressure (BP), along with tobacco use and dyslipidemia, is one of the three most important modifiable risk factors for CVD. For more than 2 decades, studies have indicated an escalating pattern of hypertension in SSA. 1,2 Estimates indicate unacceptably high rates of undiagnosed and poorly controlled disease in SSA, in spite of substantially enhanced knowledge on pharmacologic and lifestyle interventions for controlling BP. The reasons for the escalating burden of hypertension in SSA are yet fully elucidated; however, important drivers include rapid urbanization, adoption of unhealthy eating habits, and sedentary lifestyles. Addressing hypertension in SSA requires multipronged interventions to achieve better prevention, detection, and control of the condition.In this article, we discuss the urgency of prevention as a priority for hypertension control, as well as possible strategies to be employed to initiate health service and community-based actions toward the prevention of hypertension in SSA. THE DEVASTATING HUMAN AND ECONOMIC BURDEN OF HYPERTENSION IN SSAHigh BP is one of the leading causes of death and disability globally, 1,2 and significantly affects countries within SSA. Between 1990 and 2010, the prevalence of hypertension in SSA increased by 67%, and hypertension was responsible for more than 500,000 deaths and 10 million years of life lost in 2010 in the region.2 This is at variance with many other countries worldwide where absolute BP levels and prevalence of hypertension may be decreasing. 2 The prevalence of hypertension in some SSA countries are among the world's highest. A recent review showed that hypertension prevalence varies between 15% and 70%, with an average of 30%, among SSA countries.3 Furthermore, between 44% and 93% of people with hypertension in SSA are unaware of their hypertensive status.3 The extent of the adverse effects of hypertension on the health and lives of populations within SSA remains largely unexplored. Extrapolations from studies among African descents in the diaspora suggest that the outcomes of hypertension among populations in SSA are likely devastating.Indeed, the few studies conducted among SSA populations indicate that up to 42% of cases of ischemic heart disease (IHD) are related to hypertension, 4 that hypertension increases the risk of stroke by at least five-fold, 5 and that a third of heart failure cases in SSA are caused by hypertension. 6 Other potential consequences of elevated BP in SSA that are becoming increasingly common are chronic kidney disease, 7 adverse pregnancy outcomes, 8 and vascular dementia. 9 The likelihood of these poor outcomes is heightened by the low uptake of treatments for hypertension in SSA. Only about 18% of individuals with hypertension in SSA receive any treatment for hypertension, with only about 7% achieving target BP control levels. 3Treating hypertension is expensive, imposing a huge economic burden on individuals and national healthcare systems in SSA, mainly because of the costs associated with con...
