BACKGROUND: Ambulatory blood pressure (ABP) is consistently superior to clinic blood pressure (CBP) as a predictor of cardiovascular morbidity and mortality risk. A common perception is that ABP is usually lower than CBP. The relationship of the CBP minus ABP difference to age has not been examined in the United States. METHODS: Between 2005 and 2012, 888 healthy, employed, middle-aged (mean±SD age, 45±10.4 years) individuals (59% female, 7.4% black, 12% Hispanic) with screening BP <160/105 mm Hg and not taking antihypertensive medication completed 3 separate clinic BP assessments and a 24-hour ABP recording for the Masked Hypertension Study...

: Mixed findings regarding effects of vitamin E on bone metabolism existed. We were the first to find a negative association between serum α-tocopherol concentration and bone mineral density in the US elderly population. Using vitamin E supplement as α-tocopherol to promote bone health was not warranted at this time. INTRODUCTION: The aim of the study is to examine the associations between serum vitamin E (α-tocopherol and γ-tocopherol) status and bone mineral density (BMD) among the US elderly population...

BACKGROUND: Because people care about their weight relative to peers and society, obesity inequality plays a role in explaining obesity incidence and the impacts of being obese on subjective well-being. While the increase in obesity prevalence and mean body mass index (BMI) is well documented, the measurement of distributional changes and corresponding obesity inequality is yet to be fully explored. METHODS: The present study analyzed BMI data for adults aged 20 to 74 from the National Health and Nutritional Examination Survey (NHANES) I (1971-1974), II (1976-1980), III (1988-1994), and continuous NHANES (1999-2014)...

BACKGROUND: Understanding trends in the distribution of body mass index (BMI) is a critical aspect of monitoring the global overweight and obesity epidemic. Conventional population health metrics often only focus on estimating and reporting the mean BMI and the prevalence of overweight and obesity, which do not fully characterize the distribution of BMI. In this study, we propose a novel method which allows for the estimation of the entire distribution. METHODS: The proposed method utilizes the optimization algorithm, L-BFGS-B, to derive the distribution of BMI from three commonly available population health statistics: mean BMI, prevalence of overweight, and prevalence of obesity...

There are few long-term nationally representative studies of all-cause mortality among those infected with hepatitis C virus (HCV). When an additional 5 years of data were made publicly available in 2015, the Third National Health and Nutrition Examination Survey Linked Mortality File became the longest nationally representative study in the United States. Our objective was to update the estimated HCV-associated all-cause mortality in the general US population and determine any differences by sex, age and race/ethnicity...

BACKGROUND: Water, an essential nutrient, is believed to be related to a variety of health outcomes. Published studies have examined the association of fluid or beverage intake with risk of mortality from coronary diseases, diabetes, or cancer, but few studies have examined the association of total water intake with all-cause mortality. OBJECTIVE: We examined prospective risk of mortality from all causes in relation to intakes of total water and each of the 3 water sources...

To examine how the food consumption from various food groups would impact American adults' sodium intake and whether this impact structurally changes over time, data were obtained from six-cycle National Health and Nutrition Examination Survey (NHANES) 1999-2010. Foods were categorized by the first two digits of the USDA food code. Regression models were employed to investigate the associations between the consumption of each food group and sodium intake, and whether there were changes in the associations in consecutive six cycles...

BACKGROUND: Leukocyte telomere length (LTL) is a putative biological marker of immune system age, and there are demonstrated associations between LTL and cardiovascular disease. This may be due in part to the relationship of LTL with other biomarkers associated with cardiovascular disease risk. However, the strength of associations between LTL and adiposity, metabolic, proinflammatory, and cardiovascular biomarkers has not been systematically evaluated in a United States nationally representative population...

INTRODUCTION: Physical activity may protect against health consequences associated with obesity, yet less is known on how the duration of obesity alters this association, specifically as it relates to leukocyte telomere length. METHODS: The 1999-2002 NHANES was used to place individuals into 6 mutually exclusive groups based on physical activity status and weight status/duration. RESULTS: All active individuals, except for those overweight/obese for longer durations, were associated with longer telomeres in comparison to sedentary individuals...

INTRODUCTION: This study aims to determine if evidence exists for a lasting effect of the Diabetes Prevention Program (DPP) lifestyle intervention on activity levels by comparing objectively collected activity data between the DPP Outcome Study (DPPOS) cohort and adults from the National Health and Nutrition Examination Survey (NHANES; 2003-2006). METHODS: Average minutes/day of light and moderate to vigorous physical activity (MVPA) and sedentary behavior from ActiGraph accelerometers (collected 2010-2012) were examined (2013-2014) for comparable DPPOS and NHANES subgroups by age, sex, and diabetes status...

BACKGROUND: Sedentary behavior, cardiorespiratory fitness, cognition and age are interrelated and associated with cardiovascular function. No study, however, has specifically evaluated the independent and combined associations of cardiorespiratory fitness and sedentary behavior on cognition, which was this study's purpose. METHODS: Data from the 1999-2002 NHANES were used (N=2451; 60-85yrs). Sedentary behavior was assessed via self-report; cardiorespiratory fitness was assessed from a medical-related algorithm; and cognition function was assessed from the Digit Symbol Substitution Test (DSST)...

BACKGROUND: Leukocyte telomere length (LTL) is an important biomarker of aging. This study examined whether inflammatory potential of diet, as measured by the Dietary Inflammatory Index(TM) (DII) has an impact on telomere shortening in the National Health and Nutrition Examination Survey (NHANES). We also carried out validation of the DII with C-reactive protein (CRP). METHODS: Data came from NHANES 1999-2002. LTL and CRP were assayed from leukocyte DNA and serum specimens, respectively...

Immigrants' health (dis)advantages are increasingly recognized as not being uniform, leading to calls for studies investigating whether immigrant health outcomes are dependent on factors that exacerbate health risks. We answer this call, considering an outcome with competing evidence about immigrants' vulnerability versus risk: childhood obesity. More specifically, we investigate obesity among three generations of Mexican-origin youth relative to one another and to U.S.-born whites. We posit that risk is dependent on the intersection of generational status, gender, and age, which all influence exposure to U...
