Associations between human papillomavirus and history of cancer among U.S. adults in the National Health and Nutrition Examination Survey (2003-2010).

ABSTRACT: BACKGROUND: Human papillomavirus (HPV) is an infectious agent that has been associated with human cancer. We have updated the U.S. population sero-prevalence using a large National Health and Nutrition Examination Survey (NHANES) sample of adults from 2003 to 2010, and have analysed the associations between HPV seropositivity and self-reported history of cancer. METHODS: Four cross-sectional cycles (2003-2004, 2005-2006, 2007-2008, and 2009-2010) were used, for a total of 12 759 participants who had both cancer history and HPV serum information. RESULTS: The sero-prevalences of HPV types 6, 11, 16, and 18 were 15.0%, 4.8%, 11.5%, and 4.1%, respectively. Females had significantly higher HPV prevalence than males (P<0.05) for all subtypes. Positive associations between HPV 16/18 seropositivity and lifetime history of any cancer (adjusted odds ratio-ORadj=1.68; 95% CI: 1.35, 2.01), history of any of eight selected cancers (ORadj=2.63; 95% CI: 1.78, 3.90), lung cancer (ORadj=5.14; 95% CI: 1.29, 20.44), and cervical cancer (ORadj=2.55; 95% CI: 1.63, 3.98) were observed. CONCLUSIONS: The finding of significant associations between HPV 16/18 seropositivity and lifetime history of cancer adds epidemiological evidence to the carcinogenicity potential of HPV 16 and 18 in other tissues. With increasing coverage of the HPV vaccine in the U.S., future NHANES data and sample collection may allow further detailed evaluation of the population impact of the HPV vaccination on cancer prevention.

Project description:Background2,4-Dichlorophenol (2,4-DCP), 2,5-dichlorophenol (2,5-DCP), and their precursors are widely used in industry and in consumer products. Urinary concentrations of these dichlorophenols (DCPs) have been measured as part of four National Health and Nutrition Examination Survey (NHANES) cycles in order to assess the exposure to these compounds or their precursors among the general U.S. population.ObjectivesWe identified predictors and evaluated trends in DCP concentrations according to race/ethnicity, age, sex, family income, and housing type.MethodsWe used analysis of covariance to examine associations of various demographic parameters and survey cycle with urinary concentrations of DCPs during NHANES 2003-2010. We also conducted weighted logistic regressions to estimate associations of DCP concentrations above the 95th percentile with housing type, race/ethnicity, and income.ResultsWe detected DCPs in at least 81% of participants. Geometric mean (GM) urinary concentrations were higher for 2,5-DCP (6.1-12.9 ?g/L) than 2,4-DCP (0.8-1.0 ?g/L) throughout 2003-2010. Adjusted GM concentrations of the DCPs among children (6-11 years of age) and adults > 60 years of age were higher than among adolescents and other adults. Adjusted GM concentrations among non-Hispanic whites were lower than among non-Hispanic blacks and Mexican Americans, although differences according to race/ethnicity were less pronounced among participants in high-income households. Among non-Hispanic blacks and Mexican Americans, adjusted GM concentrations were lowest among high-income participants relative to other income groups, with a monotonic decrease with increasing income among Mexican Americans. Type of housing and race/ethnicity were significant predictors of DCP urinary concentrations above the 95th percentile. Furthermore, urinary DCP concentrations have showed a downward trend since 2003.ConclusionsExposure to DCPs and their precursors was prevalent in the general U.S. population in 2003-2010. We identified age and race/ethnicity, family income, and housing type as predictors of exposure to these compounds.

Project description:IntroductionBerries are a rich source of antioxidant polyphenols and other nutrients that are associated with good health. Allostatic load (AL) is an aggregate measure of chronic stress-induced physiological dysregulations across cardiovascular, metabolic, autonomic, and immune systems; the extent of these dysregulations, collectively or in each system, can be characterized by a composite score or a domain score assessed by integrated biomarkers. It was hypothesized that the anti-inflammatory and other effects of berries lower AL. The association was determined between berry consumption and AL composite and domain scores in the 2003-2010 National Health and Nutrition Examination Survey (NHANES).MethodsBerry intake was measured using two 24 h dietary recalls collected from US adults in the 2003-2010 NHANES (n = 7684). The association with AL and its specific domains was examined using population weight-adjusted multivariable linear regression.ResultsThe mean AL composite scores for consumers of any berries (11.9), strawberries (11.6), and blueberries (11.6), respectively, were significantly lower than nonconsumers (12.3), after fully adjusting for sociodemographic, lifestyle, and dietary confounders. A significant dose-response relationship was determined between greater consumption of total berries, strawberries, and blueberries and lower mean AL composite scores (p-trend < 0.05, for all). Consistently, mean cardiovascular and metabolic domain scores remained significantly lower in the consumers of total berries (mean cardiovascular domain score: 4.73 versus 4.97 for nonconsumers; mean metabolic domain score: 2.97 versus 3.1), strawberries (4.73 versus 4.95; 2.99 versus 3.1), and blueberries (4.6 versus 4.95; 2.92 versus 3.11). Berry consumers also had significantly lower mean AL immune scores (1.52 versus 1.56) and lower mean AL autonomic scores (2.49 versus 2.57) than nonconsumers (initial sample: n = 15,620).ConclusionsThe current study indicates that consumption of berries lowers the AL composite scores and potentially reduces stress-related disease risks in the US adult population.

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.
