Hypertension among US-born and foreign-born non-Hispanic Blacks: National Health and Nutrition Examination Survey 2003-2014 data.

ABSTRACT: OBJECTIVES:Non-Hispanic Blacks in the United States have the highest reported prevalence of hypertension (44%) worldwide. However, this does not consider the heterogeneity of Blacks within the United States, particularly comparing US-born to long-standing or recent (foreign-born) immigrants. The objective of this study is to compare odds of hypertension between US-born and foreign-born Blacks in the United States. METHODS:We assessed the prevalence of hypertension among US-born (n?=?4511) vs. foreign-born (n?=?522) non-Hispanic Black adults aged 22-79 years, based on pooled nationally representative data (2003-2014); as well by length of US residency among immigrants. Multivariable-adjusted logistic regression was used to investigate the association between nativity and hypertension odds. RESULTS:Nearly half (42.8%) of US-born Blacks but only 27.4% of foreign-born Blacks had hypertension. After adjusting for major covariates, foreign-born Blacks were 39.0% less likely (odds ratio 0.61 95% confidence interval 0.49, 0.77) to have hypertension than their US-born counterparts. Among foreign-born Blacks, length of US residency was not significantly associated with odds of hypertension. CONCLUSION:Foreign-born vs. US-born non-Hispanic Blacks have substantially lower prevalence of hypertension. Considering nativity among US Blacks in clinical research and public health efforts may improve accuracy of characterizing health disparities and facilitate development of targeted interventions to reduce hypertension in this diverse population.

Project description:BackgroundNon-Hispanic blacks in the United States are less likely to not meet national dietary recommendations than non-Hispanic whites; however, most studies do not consider nativity of US blacks.ObjectiveWith the use of the Alternative Healthy Eating Index-2010 (AHEI-2010) and the Dietary Approach to Stop Hypertension (DASH) scores, this cross-sectional study compared diet quality between US-born (n = 3,911) and foreign-born (n = 408) non-Hispanic black adults aged 22-79 y, based on pooled nationally representative data (NHANES 2003-2012) as well as by length of US residency.DesignThe association between nativity and diet quality was determined by using multivariable-adjusted linear regression for the continuous total diet quality scores and their components or multinomial (polytomous) logistic regression for categorical tertiles (low, medium, or high) of the total scores and their components.ResultsForeign-born blacks had significantly higher AHEI-2010 (β: 9.3; 95% CI: 7.5, 11.0) and DASH (β: 3.1; 95% CI: 2.5, 3.8) scores compared with US-born blacks and more favorable intakes for many of the score components. Among foreign-born blacks, diet quality did not significantly differ by length of residency. Foreign-born blacks were more likely to be in the high than in the low tertile for vegetables [excluding starchy vegetables; relative risk ratio (RRR): 1.68; 95% CI: 1.24, 2.29], fruit [excluding and including fruit juice-RRR: 2.42 (95% CI: 1.69, 3.47) and RRR: 2.95 (95% CI: 1.90, 4.59), respectively], percentage of whole grains (RRR: 2.39; 95% CI: 1.64, 3.49), and omega-3 (ω-3) fatty acids (RRR: 2.03; 95% CI: 1.38, 2.97).ConclusionsForeign-born blacks have better diet quality than their US-born counterparts. In nutrition research and public health efforts, considering the place of birth among US blacks may improve the accuracy of characterizing dietary intakes and facilitate the development of targeted nutrition interventions to reduce diet-related diseases in the diverse black population in the United States.

Project description:Background Current studies on the protective effects of dietary spermidine (SPD) on cardiovascular disease (CVD) are mainly limited to animal studies, and the relationship between dietary SPD and CVD mortality remains inconclusive. Objective This study aims to evaluate the association between dietary SPD intake and CVD and all-cause mortality. Methods A total of 23,894 people enrolled in the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2014 were recruited for this study. The dietary intake of SPD from 11 specific food origins and total SPD was categorized into tertiles or quartiles. Cox proportional hazard regression models were developed to evaluate the association of SPD intake with CVD and all-cause mortalities. Results Among the 23,894 participants, 2,365 deaths, including 736 deaths due to CVD, were documented. After adjustment for potential confounders, compared with participants in the lowest quartile, participants in the highest quartile of total SPD had a significantly lower risk of CVD mortality (HR = 0.68, 95% CI: 0.51–0.91) and all-cause mortality (HR = 0.70, 95% CI: 0.60–0.82); participants in the highest tertiles or quartiles of vegetable-derived SPD, cereal-derived SPD, legume-derived SPD, nut-derived SPD, and cheese-derived SPD had a lower risk of CVD mortality (HR vegetable − derivedSPD = 0.68, 95% CI: 0.54–0.86; HR cereal − derivedSPD = 0.75, 95% CI: 0.57–0.97; HR legume − derivedSPD = 0.68, 95% CI: 0.52–0.88; HR nut − derivedSPD = 0.66, 95% CI: 0.53–0.80; HR cheese − derivedSPD = 0.68, 95% CI: 0.52–0.88) and all-cause mortality (HR vegetable − derivedSPD = 0.73, 95% CI: 0.64–0.84; HR cereal − derivedSPD = 0.80, 95% CI: 0.69–0.93; HR legume − derivedSPD = 0.70, 95% CI: 0.60–0.80;HR nut − derivedSPD = 0.72, 95% CI: 0.64–0.81; HR cheese − derivedSPD = 0.70, 95% CI: 0.61–0.81) than those in the lowest tertiles or quartiles. Moreover, subgroup analysis showed consistent associations among the people with hypertension and hyperlipidemia. Conclusion Higher intake of dietary SPD is associated with decreased risk of CVD and all-cause mortality, and among specific food origin SPD, SPD derived from vegetables, cereals, legumes, nuts, and cheese was associated with reduced CVD and all-cause mortality.

Project description:BackgroundIntake time of diet has recently been demonstrated to be associated with the internal clock and circadian pattern. However, whether and how the intake time of minerals would influence the natural course of cancer was largely unknown.MethodsThis study aimed to assess the association of mineral intake at different periods with cancer and all-cause mortality. A total of 27,455 participants aged 18-85 years old in the National Health and Nutrition Examination Survey were recruited. The main exposures were the mineral intakes in the morning, afternoon and evening, which were categorized into quintiles, respectively. The main outcomes were mortality of cancer and all causes.ResultsDuring the 178,182 person-years of follow-up, 2680 deaths, including 601 deaths due to cancer, were documented. After adjusting for potential confounders, compared to the participants who were in the lowest quintile(quintile-1) of mineral intakes at dinner, the participants in the highest quintile intake(quintile-5) of dietary potassium, calcium and magnesium had lower mortality risks of cancer (HRpotassium = 0.72, 95% CI:0.55-0.94, P for trend = 0.023; HRcalcium = 0.74, 95% CI:0.57-0.98, P for trend = 0.05; HRmagnesium = 0.75, 95% CI:0.56-0.99, P for trend = 0.037) and all-cause (HRpotassium = 0.83, 95% CI:0.73-0.94, P for trend = 0.012; HRcalcium = 0.87, 95% CI:0.76-0.99, P for trend = 0.025; HRmagnesium = 0.85, 95% CI:0.74-0.97, P for trend = 0.011; HRcopper = 0.80, 95%CI: 0.68-0.94, P for trend = 0.012). Further, equivalently replacing 10% of dietary potassium, calcium and magnesium consumed in the morning with those in the evening were associated with lower mortality risk of cancer (HRpotassium = 0.94, 95%CI:0.91-0.97; HRcalcium = 0.95, 95%CI:0.92-0.98; HRmagnesium = 0.95, 95%CI: 0.92-0.98).ConclusionsThis study demonstrated that the optimal intake time of potassium, calcium and magnesium for reducing the risk of cancer and all-cause mortality was in the evening.
