    ABSTRACT: Current recommendations target sodium reduction in the food supply and intake; however, information is limited on consumer readiness for these actions. Prevalence and determinants of consumer agreement for government restriction of manufacturers and restaurants putting excess salt in food and support for policies limiting sodium content of quick service restaurant (QSR) foods were examined. Data were analyzed from 9,579 adults aged ≥18 years who responded to consumer readiness for sodium reduction questions in the 2010 ConsumerStyles survey. Responses were collapsed into three categories. Consumer agreement was determined and logistic regression was used to estimate ORs. Analyses were conducted in 2012. The majority of consumers agree that it is a good idea for government to restrict food manufacturers (55.9%) from putting excess salt in foods. About half agreed that it is a good idea for government to restrict restaurants from putting excess salt in foods and 81.5% supported sodium reduction policies in QSRs. Odds of agreement/support were higher for non-Hispanic blacks compared with non-Hispanic whites, and those with incomes <$40,000 compared with ≥$60,000. Those reporting "neutral" or "yes" to wanting to eat a diet low in sodium were more likely to agree/support government action compared to those answering "no." Nearly half of consumers agree with government actions to reduce sodium in manufactured and restaurant foods, with even greater support for QSRs. These findings could inform industry and public health partners about consumer preferences to lower the sodium content of the food supply.

    ABSTRACT: BACKGROUND In a recent study, high maternal periconceptional intake of vitamin E was found to be associated with risk of congenital heart defects (CHDs). To explore this association further, we investigated the association between total daily vitamin E intake and selected birth defects. METHODS: We analyzed data from 4525 controls and 8665 cases from the 1997 to 2005 National Birth Defects Prevention Study. We categorized estimated periconceptional energy-adjusted total daily vitamin E intake from diet and supplements into quartiles (referent, lowest quartile). Associations between quartiles of energy-adjusted vitamin E intake and selected birth defects were adjusted for demographic, lifestyle, and nutritional factors. RESULTS: We observed a statistically significant association with the third quartile of vitamin E intake (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.01–1.35) and all CHDs combined. Among CHD sub-types, we observed associations with left ventricular outflow tract obstruction defects, and its sub-type, coarctation of the aorta and the third quartile of vitamin E intake. Among defects other than CHDs, we observed associations between anorectal atresia and the third quartile of vitamin E intake (OR, 1.66; 95% CI, 1.01–2.72) and hypospadias and the fourth quartile of vitamin E intake (OR, 1.42; 95% CI, 1.09–1.87). CONCLUSION: Selected quartiles of energy-adjusted estimated total daily vitamin E intake were associated with selected birth defects. However, because these few associations did not exhibit exposure-response patterns consistent with increasing risk associated with increasing intake of vitamin E, further studies are warranted to corroborate our findings.

    ABSTRACT: Little information is available on temporal trends in sodium intake in the U.S. population using urine sodium excretion as a biomarker. Our aim was to assess 1988-2010 trends in estimated 24-h urine sodium (24hUNa) excretion among U.S. adults (age 20-59 y) participating in the cross-sectional NHANES. We used subsamples from a 1988-1994 convenience sample, a 2003-2006 one-third random sample, and a 2010 one-third random sample to comply with resource constraints. We estimated 24hUNa excretion from measured sodium concentrations in spot urine samples by use of calibration equations (for men and women) derived from the International Cooperative Study on Salt, Other Factors, and Blood Pressure study. Estimated 24hUNa excretion increased over the 20-y period [1988-1994, 2003-2006, and 2010; means ± SEMs (n): 3160 ± 38.4 mg/d (1249), 3290 ± 29.4 mg/d (1235), and 3290 ± 44.4 mg/d (525), respectively; P-trend = 0.022]. We observed significantly higher mean estimated 24hUNa excretion in each survey period (P < 0.001) for men compared with women (31-33%) and for persons with a higher body mass index (BMI; 32-35% for obese vs. normal weight) or blood pressure (17-26% for hypertensive vs. normal blood pressure). After adjusting for age, sex, and race-ethnicity, temporal trends in mean estimated 24hUNa excretion remained significant (P-trend = 0.004). We observed no temporal trends in mean estimated 24hUNa excretion among BMI subgroups, nor after adjusting for BMI. Although several limitations apply to this analysis (the use of a convenience sample in 1988-1994 and using estimated 24hUNa excretion as a biomarker of sodium intake), these first NHANES data suggest that mean estimated 24hUNa excretion increased slightly in U.S. adults over the past 2 decades, and this increase may be explained by a shift in the distribution of BMI.

    ABSTRACT: The vast majority of Americans consume too much sodium, primarily from packaged and restaurant foods. The evidence linking sodium intake with direct health outcomes indicates a positive relationship between higher levels of sodium intake and cardiovascular disease risk, consistent with the relationship between sodium intake and blood pressure. Despite communication and educational efforts focused on lowering sodium intake over the last three decades data suggest average US sodium intake has remained remarkably elevated, leading some to argue that current sodium guidelines are unattainable. The IOM in 2010 recommended gradual reductions in the sodium content of packaged and restaurant foods as a primary strategy to reduce US sodium intake, and research since that time suggests gradual, downward shifts in mean population sodium intake are achievable and can move the population toward current sodium intake guidelines. The current paper reviews recent evidence indicating: (1) significant reductions in mean population sodium intake can be achieved with gradual sodium reduction in the food supply, (2) gradual sodium reduction in certain cases can be achieved without a noticeable change in taste or consumption of specific products, and (3) lowering mean population sodium intake can move us toward meeting the current individual guidelines for sodium intake.

    ABSTRACT: Background: Median urine iodine concentration (UIC; µg/L) in spot urine samples is recommended for monitoring population iodine status. Other common measures are iodine:creatinine ratio (I/Cr; µg/g) and estimated 24-hr urine iodine excretion (UIE; I/Cr*predicted 24-hr Cr; µg/d). Despite different units, these measures are often used interchangeably, and it is unclear how they compare with the reference standard 24-hr UIE. Methods: Volunteers aged 18-39y collected all their urine samples for 24-hours (n=400); voids from morning, afternoon, evening, overnight, and a composite 24-h sample were analyzed for iodine. We calculated median observed 24-hr UIE and 24-hr UIC, and spot UIC, I/Cr, and 2 measures of estimated UIE calculated using predicted 24-hr Cr from published estimates by Kesteloot & Joosens (varies by age and sex) and published equations by Mage (varies by age, sex, race, and anthropometric measures). We examined mean differences and relative difference across iodine excretion levels using Bland-Altman plots. Results: Median 24-hr UIE was 173.6 µg/d and 24-hr UIC was 144.8 µg/L. From timed spot urine samples, estimates were UIC: 147.3-156.2 µg/L, I/Cr: 103.6-114.3 µg/g, estimated 24-hr UIE (Kesteloot & Joosens): 145.7-163.3 µg/d, and estimated 24-hr UIE (Mage): 176.5-187.7 µg/d. Iodine measures did not vary consistently by timing of spot urine collection. Compared with observed 24-hr UIE, on average, estimated (Mage) 24-hr UIE was not significantly different, while estimated 24-hr UIE (Kesteloot& Joosens) was significantly different for some race/sex groups. Compared with 24-hr UIC, on average, spot UIC did not differ. Conclusions: Estimates of UIC, I/Cr, and estimated 24h-hr UIE (I/Cr*predicted 24-hr Cr) from spot urine samples should not be used interchangeably. Estimated 24-hr UIE, where predicted 24-hr Cr varies by age, sex, race, and anthropometric measures and was calculated with prediction equations using data from the sample, was more comparable to observed 24-hr UIE than when predicted 24-hr Cr was from published estimates from a different population. However, currently no cutoffs exist to interpret population estimated 24-hr UIE values.

    ABSTRACT: Collecting a 24-h urine sample is recommended for monitoring the mean population sodium intake, but implementation can be difficult. The objective was to assess the validity of published equations by using spot urinary sodium concentrations to predict 24-h sodium excretion. This was a cross-sectional study, conducted from June to August 2011 in metropolitan Washington, DC, of 407 adults aged 18-39 y, 48% black, who collected each urine void in a separate container for 24 h. Four timed voids (morning, afternoon, evening, and overnight) were selected from each 24-h collection. Published equations were used to predict 24-h sodium excretion with spot urine by specimen timing and race-sex subgroups. We examined mean differences with measured 24-h sodium excretion (bias) and individual differences with the use of Bland-Altman plots. Across equations and specimens, mean bias in predicting 24-h sodium excretion for all participants ranged from -267 to 1300 mg (Kawasaki equation). Bias was least with International Cooperative Study on Salt, Other Factors, and Blood Pressure (INTERSALT) equations with morning (-165 mg; 95% CI: -295 mg, 36 mg), afternoon (-90; -208, 28), and evening (-120; -230, -11) specimens. With overnight specimens, mean bias was least when the Tanaka (-23; 95% CI: -141, 95) or Mage (-145; -314, 25) equations were used but was statistically significant with the Tanaka equations in females (216-243 mg) and the Mage equations in races other than black (-554, -372 mg). Significant over- and underprediction occurred across individual sodium excretion concentrations. Using a single spot urine, INTERSALT equations may provide the least biased information about population mean sodium intakes among young US adults. None of the equations evaluated provided unbiased estimates of individual 24-h sodium excretion. This trial was registered at clinicaltrials.gov as NCT01631240.

    ABSTRACT: Data are limited on usual sodium and potassium intakes relative to age-specific recommendations and the sodium:potassium ratio in infants and preschoolers, especially among those aged <2 y, who are black or breastfed. The usual sodium intake above the Tolerable Upper Intake Levels (ULs), potassium intakes above Adequate Intakes (AIs), the sodium:potassium ratio, and sodium density (mg/kcal) among US infants and preschoolers by age group, as applicable, were estimated and compared by race-ethnicity and current breastfeeding status. Data were analyzed among 3 groups of children (aged 7-11 mo, 1-3 y, and 4-5 y) from the NHANES 2003-2010 by using measurement error models. Seventy-nine percent of children aged 1-3 y and 87% of those aged 4-5 y exceeded their sodium UL; among non-Hispanic black children, the estimates were 84% and 97%, respectively. For potassium, 97% of infants, 5% of children aged 1-3 y, and 0.4% aged 4-5 y met their AIs. Compared with non-Hispanic whites and Mexican Americans, non-Hispanic black infants and preschoolers had higher mean sodium density and sodium:potassium ratios. Currently breastfed infants and children consumed, on average, less sodium than those who were not breastfed (382 ± 53 compared with 538 ± 22 mg in those aged 7-11 mo and 1154 ± 88 compared with 1985 ± 24 mg in those aged 1-3 y, respectively), but the sodium:potassium ratio did not differ. Most US preschoolers, particularly non-Hispanic blacks, consume too much sodium, and nearly all do not consume enough potassium. Data that suggest that currently breastfed infants consume less sodium than do those who are not breastfeeding merit further investigation.

    ABSTRACT: The objective of this review is to evaluate the literature on the association between mild, moderate, and binge prenatal alcohol exposure and child neurodevelopment. Meta-analysis with systematic searches of MEDLINE (1970 through August 2012), EMBASE (1988 through August 2012), and PsycINFO(®) (1970 through August 2012) and examination of selected references. From 1,593 articles, we identified 34 presenting data from cohort studies that met our inclusion criteria. Information on study population, outcomes, measurement instruments, timing and quantification of alcohol exposure, covariates, and results was abstracted. Outcomes included academic performance, attention, behavior, cognition, language skills, memory, and visual and motor development. The quality of each article was assessed by 2 researchers using the Newcastle-Ottawa Scale. Based on 8 studies of 10,000 children aged 6 months through 14 years, we observed a significant detrimental association between any binge prenatal alcohol exposure and child cognition (Cohen's d [a standardized mean difference score] -0.13; 95% confidence interval [CI], -0.21, -0.05). Based on 3 high-quality studies of 11,900 children aged 9 months to 5 years, we observed a statistically significant detrimental association between moderate prenatal alcohol exposure and child behavior (Cohen's d -0.15; 95% CI, -0.28, -0.03). We observed a significant, albeit small, positive association between mild-to-moderate prenatal alcohol exposure and child cognition (Cohen's d 0.04; 95% CI, 0.00, 0.08), but the association was not significant after post hoc exclusion of 1 large study that assessed mild consumption nor was it significant when including only studies that assessed moderate alcohol consumption. None of the other completed meta-analyses resulted in statistically significant associations between mild, moderate, or binge prenatal alcohol exposure and child neuropsychological outcomes. Our findings support previous findings suggesting the detrimental effects of prenatal binge drinking on child cognition. Prenatal alcohol exposure at levels less than daily drinking might be detrimentally associated with child behavior. The results of this review highlight the importance of abstaining from binge drinking during pregnancy and provide evidence that there is no known safe amount of alcohol to consume while pregnant.

    ABSTRACT: We reviewed methods of studies assessing restaurant foods' sodium content and nutrition databases. We systematically searched the 1964-2012 literature and manually examined references in selected articles and studies. Twenty-six (5.2%) of the 499 articles we found met the inclusion criteria and were abstracted. Five were conducted nationally. Sodium content determination methods included laboratory analysis (n = 15), point-of-purchase nutrition information or restaurants' Web sites (n = 8), and menu analysis with a nutrient database (n = 3). There is no comprehensive data system that provides all information needed to monitor changes in sodium or other nutrients among restaurant foods. Combining information from different sources and methods may help inform a comprehensive system to monitor sodium content reduction efforts in the US food supply and to develop future strategies.

    ABSTRACT: Because of the logistic complexity, excessive respondent burden, and high cost of conducting 24-h urine collections in a national survey, alternative strategies to monitor sodium intake at the population level need to be evaluated. We conducted a calibration study to assess the ability to characterize sodium intake from timed-spot urine samples calibrated to a 24-h urine collection. In this report, we described the overall design and basic results of the study. Adults aged 18-39 y were recruited to collect urine for a 24-h period, placing each void in a separate container. Four timed-spot specimens (morning, afternoon, evening, and overnight) and the 24-h collection were analyzed for sodium, potassium, chloride, creatinine, and iodine. Of 481 eligible persons, 407 (54% female, 48% black) completed a 24-h urine collection. A subsample (n = 133) collected a second 24-h urine 4-11 d later. Mean sodium excretion was 3.54 ± 1.51 g/d for males and 3.09 ± 1.26 g/d for females. Sensitivity analysis excluding those who did not meet the expected creatinine excretion criterion showed the same results. Day-to-day variability for sodium, potassium, chloride, and iodine was observed among those collecting two 24-h urine samples (CV = 16-29% for 24-h urine samples and 21-41% for timed-spot specimens). Among all race-gender groups, overnight specimens had larger volumes (P < 0.01) and lower sodium (P < 0.01 -P = 0.26), potassium (P < 0.01), and chloride (P < 0.01) concentrations compared with other timed-spot urine samples, although the differences were not always significant. Urine creatinine and iodine concentrations did not differ by the timing of collection. The observed day-to-day and diurnal variations in sodium excretion illustrate the importance of accounting for these factors when developing calibration equations from this study.

    ABSTRACT: High intakes of dietary sodium are associated with elevated blood pressure levels and an increased risk of cardiovascular disease. National and international guidelines recommend reduced sodium intake in the general population, which necessitates population-wide surveillance. We assessed the utility of casual (spot) urine specimens in estimating 24-hour urinary sodium excretion as a marker of sodium intake in the International Cooperative Study on Salt, Other Factors, and Blood Pressure. There were 5,693 participants recruited in 1984-1987 at the ages of 20-59 years from 29 North American and European samples. Participants were randomly assigned to test or validation data sets. Equations derived from casual urinary sodium concentration and other variables in the test data were applied to the validation data set. Correlations between observed and estimated 24-hour sodium excretion were 0.50 for individual men and 0.51 for individual women; the values were 0.79 and 0.71, respectively, for population samples. Bias in mean values (observed minus estimated) was small; for men and women, the values were -1.6 mmol per 24 hours and 2.3 mmol per 24 hours, respectively, at the individual level and -1.8 mmol per 24 hours and 2.2 mmol per 24 hours, respectively, at the population level. Proportions of individuals with urinary 24-hour sodium excretion above the recommended levels were slightly overestimated by the models. Casual urine specimens may be a useful, low-burden, low-cost alternative to 24-hour urine collections for estimation of population sodium intakes; ongoing calibration with study-specific 24-hour urinary collections is recommended to increase validity.

    ABSTRACT: BACKGROUND Beyond perinatal folic acid supplementation, the need for additional prenatal prophylaxis of iron with or without other micronutrients remains unclear. We aim to investigate the maternal and infant health effects of iron plus folic acid and multiple micronutrient supplements vs folic acid alone when provided to pregnant women with no or mild anemia. METHODS In this randomized double-blind controlled trial, 18 775 nulliparous pregnant women with mild or no anemia were enrolled from 5 counties of northern China from May 2006 through April 2009. Women were randomly assigned to daily folic acid (400 μg) (control), folic acid-iron (30 mg), or folic acid, iron, and 13 additional vitamins and minerals provided before 20 weeks gestation to delivery. Primary outcome was perinatal mortality. Secondary outcomes included neonatal and infant mortality, preterm delivery, birth weight, birth length, gestational duration, and maternal hemoglobin concentration and anemia. RESULTS A total of 92.7% of women consumed 80% to 100% of supplements as instructed. On average, women consumed 177 supplements. Compared with daily prenatal folic acid, supplementation with iron-folic acid with or without other micronutrients did not affect the rate of perinatal mortality (8.8, 8.7, and 8.3, respectively) per 1000 births, and relative risks (RRs) were 1.00 (95% CI, 0.68-1.46; P = .99) and 0.94 (95% CI, 0.64-1.39; P = .76), respectively. Risk of other adverse maternal and infant outcomes also did not differ, except that RRs for third-trimester maternal anemia were 0.72 (95% CI, 0.63-0.83; P < .001) and 0.71 (95% CI, 0.62-0.82; P < .001), respectively. CONCLUSION Prenatal iron-folic acid and other micronutrient supplements provided to Chinese women with no or mild anemia prevented later pregnancy anemia beyond any benefit conferred by folic acid alone but did not affect perinatal mortality or other infant outcomes.

    ABSTRACT: Studies indicate high sodium and low potassium intake can increase blood pressure suggesting the ratio of sodium-to-potassium may be informative. Yet, limited studies examine the association of the sodium-to-potassium ratio with blood pressure and hypertension. We analyzed data on 10,563 participants aged ≥20 years in the 2005-2010 National Health and Nutrition Examination Survey who were neither taking anti-hypertensive medication nor on a low sodium diet. We used measurement error models to estimate usual intakes, multivariable linear regression to assess their associations with blood pressure, and logistic regression to assess their associations with hypertension. The average usual intakes of sodium, potassium and sodium-to-potassium ratio were 3,569 mg/d, 2,745 mg/d, and 1.41, respectively. All three measures were significantly associated with systolic blood pressure, with an increase of 1.04 mmHg (95% CI, 0.27-1.82) and a decrease of 1.24 mmHg (95% CI, 0.31-2.70) per 1,000 mg/d increase in sodium or potassium intake, respectively, and an increase of 1.05 mmHg (95% CI, 0.12-1.98) per 0.5 unit increase in sodium-to-potassium ratio. The adjusted odds ratios for hypertension were 1.40 (95% CI, 1.07-1.83), 0.72 (95% CI, 0.53-0.97) and 1.30 (95% CI, 1.05-1.61), respectively, comparing the highest and lowest quartiles of usual intake of sodium, potassium or sodium-to-potassium ratio. Our results provide population-based evidence that concurrent higher sodium and lower potassium consumption are associated with hypertension.

    ABSTRACT: Sodium intake is related to blood pressure, an established risk factor for heart disease and stroke. Reducing intake may save billions in United States health care dollars annually. Efforts targeting sodium reductions make accurate monitoring vital, yet limited information exists on the accuracy of the current data to assess sodium intake in the United States population. In this symposium, new findings were presented on the accuracy of estimating population 24-h urinary excretion of sodium from spot urine specimens or sodium intake from 24-h dietary recalls. Differences in accuracy by sex, BMI, and race were apparent as well as by timing of spot urine collections. Although some published equations appear promising for estimating group means, others are biased. Individual estimates of sodium intake were highly variable and adjustment for within-individual variation in intake is required for estimating population prevalence or percentiles. Estimates indicated United States sodium intake remains high.

    ABSTRACT: INTRODUCTION: In 2005, mean sodium content in school lunches was 1442 mg, which is two-thirds the recommended limit (2300 mg/day) for most children and just below the limit for African-American children (1500 mg/day). Reducing the sodium content of school meals is one of the recommendations by the Institute of Medicine to reduce US sodium intake and is required by USDA's new meal standards. We assessed consumer support for policies lowering sodium content of school cafeteria foods. METHODS: Data were used from 9,634 adults aged >18 years who responded to questions about sodium in general and in school foods on a 2010 mail panel survey. Estimates were weighted to the US census population. RESULTS: Ninety percent (95% confidence interval (CI): 89%-91%) of respondents reported they strongly (52%, CI: 51%-54%) or slightly (38%, CI: 36%-39%) support policies that lower the sodium/salt content of cafeteria foods in schools. Regardless of age, sex, race-ethnicity, body mass index, or parental status, US adult support remained at or above 78%. The highest support (strongly or slightly) rate came from respondents who reported wanting to eat a diet low in sodium (95%, CI: 94%-96%) and non-Hispanic blacks (94%, CI: 92%-96%). DISCUSSION: Our results suggest most US adults support policies that lower sodium content in school cafeteria foods. While widespread support is promising, this does not always translate into action. Strategies for change include working with a diverse group of stakeholders to adopt strong nutrition standards for school foods and engaging students to become advocates for change.

    ABSTRACT: The average adult in the United States of America consumes well above the recommended daily limit of sodium. Average sodium intake is about 3 463 mg/day, as compared to the 2010 dietary guidelines for Americans recommendation of < 2 300 mg/day. A further reduction to 1 500 mg/day is advised for people 51 years or older; African Americans; and people with high blood pressure, diabetes, or chronic kidney disease. In the United States of America, the problem of excess sodium intake is related to the food supply. Most sodium consumed comes from packaged, processed, and restaurant foods and therefore is in the product at the time of purchase. This paper describes sodium reduction policies and programs in the United States at the federal, state, and local levels; efforts to monitor the health impact of sodium reduction; ways to assess consumer knowledge, attitudes, and behavior; and how these activities depend on and inform global efforts to reduce sodium intake. Reducing excess sodium intake is a public health opportunity that can save lives and health care dollars in the United States and globally. Future efforts, including sharing successes achieved and barriers identified in the United States and globally, may quicken and enhance progress.

    ABSTRACT: To assess the association between usual dietary sodium intake and blood pressure among US children and adolescents, overall and by weight status. Children and adolescents aged 8 to 18 years (n = 6235) who participated in NHANES 2003-2008 comprised the sample. Subjects' usual sodium intake was estimated by using multiple 24-hour dietary recalls. Linear or logistic regression was used to examine association between sodium intake and blood pressure or risk for pre-high blood pressure and high blood pressure (pre-HBP/HPB). Study subjects consumed an average of 3387 mg/day of sodium, and 37% were overweight/obese. Each 1000 mg per day sodium intake was associated with an increased SD score of 0.097 (95% confidence interval [CI] 0.006-0.188, ∼1.0 mm Hg) in systolic blood pressure (SBP) among all subjects and 0.141 (95% CI: -0.010 to 0.298, ∼1.5 mm Hg) increase among overweight/obese subjects. Mean adjusted SBP increased progressively with sodium intake quartile, from 106.2 mm Hg (95% CI: 105.1-107.3) to 108.8 mm Hg (95% CI: 107.5-110.1) overall (P = .010) and from 109.0 mm Hg (95% CI: 107.2-110.8) to 112.8 mm Hg (95% CI: 110.7-114.9; P = .037) among those overweight/obese. Adjusted odds ratios comparing risk for pre-HBP/HPB among subjects in the highest versus lowest sodium intake quartile were 2.0 (95% CI: 0.95-4.1, P = .062) overall and 3.5 (95% CI: 1.3-9.2, P = .013) among those overweight/obese. Sodium intake and weight status appeared to have synergistic effects on risk for pre-HBP/HPB (relative excess risk for interaction = 0.29 (95% CI: 0.01-0.90, P < .05). Sodium intake is positively associated with SBP and risk for pre-HBP/HPB among US children and adolescents, and this association may be stronger among those who are overweight/obese.
