          Abstract

          Background

          Hypertension is highly prevalent among recent sub-Saharan African (SSA) migrants in western countries and some tend to associate their hypertension to psychosocial stress. However data on the relationship between hypertension and psychosocial stress among SSA migrants are rare. We assessed the relationship between psychosocial stress and hypertension among the largest SSA migrant population (Ghanaians) in Amsterdam, the Netherlands.

          Methods

          Data were obtained from structured interviews along with medical examination among 212 participants from a cross-sectional study: the GHAIA study in 2010 in Amsterdam. Blood pressure was measured with a validated Oscillometric automated digital blood pressure device. Psychosocial stress was assessed by questionnaires on perceived discrimination, depressive symptoms and financial problems. Binary logistic regression was used to study associations between psychosocial stress and hypertension.

          Results

          The overall prevalence of hypertension was 54.7% . About two thirds of the study population experienced a moderate (31%) or high (36%) level of discrimination. 20.0% of the participants had mild depressive symptoms, whilst 9% had moderate depressive symptoms. The prevalence of financial stress was 34.8%. The psychosocial stresses we assessed were not significantly associated with hypertension: adjusted odds ratios comparing those with low levels and those with high levels were 0.99 (95% CI, 0.47–2.08) for perceived discrimination, 0.81 (95% CI, 0.26–2.49) for depressive symptoms and 0.71 (95% CI, 0.37–1.36) for financial stress, respectively.

          Conclusion

          We did not find evidence for the association between psychosocial stress and hypertension among recent SSA migrants. More efforts are needed to unravel other potential factors that may underlie the high prevalence of hypertension among these populations.

          Trends in prevalence, awareness, treatment, and control of hypertension in the United States, 1988-2000.

          Prior analyses of National Health and Nutrition Examination Survey (NHANES) data through 1991 have suggested that hypertension prevalence is declining, but more recent self-reported rates of hypertension suggest that the rate is increasing. To describe trends in the prevalence, awareness, treatment, and control of hypertension in the United States using NHANES data. Survey using a stratified multistage probability sample of the civilian noninstitutionalized population. The most recent NHANES survey, conducted in 1999-2000 (n = 5448), was compared with the 2 phases of NHANES III conducted in 1988-1991 (n = 9901) and 1991-1994 (n = 9717). Individuals aged 18 years or older were included in this analysis. Hypertension, defined as a measured blood pressure of 140/90 mm Hg or greater or reported use of antihypertensive medications. Hypertension awareness and treatment were assessed with standardized questions. Hypertension control was defined as treatment with antihypertensive medication and a measured blood pressure of less than 140/90 mm Hg. In 1999-2000, 28.7% of NHANES participants had hypertension, an increase of 3.7% (95% confidence interval [CI], 0%-8.3%) from 1988-1991. Hypertension prevalence was highest in non-Hispanic blacks (33.5%), increased with age (65.4% among those aged > or =60 years), and tended to be higher in women (30.1%). In a multiple regression analysis, increasing age, increasing body mass index, and non-Hispanic black race/ethnicity were independently associated with increased rates of hypertension. Overall, in 1999-2000, 68.9% were aware of their hypertension (nonsignificant decline of -0.3%; 95% CI, -4.2% to 3.6%), 58.4% were treated (increase of 6.0%; 95% CI, 1.2%-10.8%), and hypertension was controlled in 31.0% (increase of 6.4%; 95% CI, 1.6%-11.2%). Women, Mexican Americans, and those aged 60 years or older had significantly lower rates of control compared with men, younger individuals, and non-Hispanic whites. Contrary to earlier reports, hypertension prevalence is increasing in the United States. Hypertension control rates, although improving, continue to be low. Programs targeting hypertension prevention and treatment are of utmost importance.

            The role of size at birth and postnatal catch-up growth in determining systolic blood pressure: a systematic review of the literature.

            To conduct a systematic review in order to (i) summarize the relationship between birthweight and blood pressure, following numerous publications in the last 3 years, (ii) assess whether other measures of size at birth are related to blood pressure, and (iii) study the role of postnatal catch-up growth in predicting blood pressure. All papers published between March 1996 and March 2000 that examined the relationship between birth weight and systolic blood pressure were identified and combined with the papers examined in a previous review. More than 444,000 male and female subjects aged 0-84 years of all ages and races. Eighty studies described the relationship of blood pressure with birth weight The majority of the studies in children, adolescents and adults reported that blood pressure fell with increasing birth weight, the size of the effect being approximately 2 mmHg/kg. Head circumference was the only other birth measurement to be most consistently associated with blood pressure, the magnitude of the association being a decrease in blood pressure by approximately 0.5 mmHg/cm. Skeletal and non-skeletal postnatal catch-up growth were positively associated with blood pressure, with the highest blood pressures occurring in individuals of low birth weight but high rates of growth subsequently. Both birth weight and head circumference at birth are inversely related to systolic blood pressure. The relationship is present in adolescence but attenuated compared to both the pre- and post-adolescence periods. Accelerated postnatal growth is also associated with raised blood pressure.

              Does psychosocial stress cause hypertension? A systematic review of observational studies.

              Acute stress promotes transient elevation of blood pressure, but there is no consistent evidence that this effect results in hypertension. In this systematic review of cohort and case-control studies that investigated the association between psychosocial stress and hypertension, we conducted a complete search up to February 2007 in MEDLINE, EMBASE, PSYCINFO and LILACS, through a search strategy that included eight terms to describe the exposure, six related to the design of the studies and one term for outcome. The quality was assessed by the Newcastle-Ottawa Quality Assessment Scale. The selection was done in duplicate by two teams of independent reviewers. Among 82 studies selected in the second phase, only 14 (10 cohort studies and 4 case-control studies), totalling 52,049 individuals, fulfilled the selection criteria. The average quality of the studies was 6.6+/-1.3 in a 9-point scale. Acute life events were associated with hypertension in one and were not associated in two studies. Five out of seven studies found a significant and positive association between measures of chronic stress and hypertension, with risk ratios ranging from 0.8 to 11.1. Three out of five studies reported high and significant risks of affective response to stress for hypertension, one a significant risk close to a unit and one reported absence of risk. Acute stress is probably not a risk factor for hypertension. Chronic stress and particularly the non-adaptive response to stress are more likely causes of sustained elevation of blood pressure. Studies with better quality are warranted.
