Project description:BackgroundIn the United States, current guidelines recommend a total sodium intake <2,300 mg/day, a guideline which does not consider kilocalorie intake. However, kilocalorie intake varies substantially by age and sex. We hypothesized that compared with sodium density, total sodium intake overestimates adherence to sodium recommendations, especially in adults consuming fewer kilocalories.MethodsIn the National Health and Nutrition Examination Survey (NHANES), we estimated the prevalence of adherence to sodium intake recommendations (<2,300 mg/day) and corresponding sodium density intake (<1.1 mg/kcal = 2,300 mg at 2,100 kcal) by sex, age, race/ethnicity, and kilocalorie level. Adherence estimates were compared between the 2005-2006 (n = 5,060) and 2015-2016 (n = 5,266) survey periods.ResultsIn 2005-2006, 23.1% (95% confidence interval [CI]: 21.5, 24.9) of the US population consumed <2,300 mg of sodium/day, but only 8.5% (CI: 7.6, 9.4) consumed <1.1 mg/kcal in sodium density. In 2015-2016, these figures were 20.9% (CI: 18.8, 23.2) and 5.1% (CI: 4.4, 6.0), respectively. In 2015-2016, compared with 2005-2006, adherence by sodium density decreased more substantially (odds ratio = 0.59; CI: 0.48, 0.72; P < 0.001) than adherence by total sodium consumption (odds ratio = 0.85; CI: 0.73, 0.98; P = 0.03). The difference in adherence between total sodium and sodium density goals was greater among those with lower kilocalorie intake, namely, older adults, women, and Hispanic adults.ConclusionsAdherence estimated by sodium density is substantially less than adherence estimated by total sodium intake, especially among persons with lower kilocalorie intake. Further efforts to achieve population-wide reduction in sodium density intake are urgently needed.

Project description:BackgroundEnergy intake is a key determinant of weight.ObjectiveOur objective was to examine trends in energy intake in adults in the United States from 1971-1975 to 2009-2010.DesignThe study was a trend analysis of 9 national surveys in the United States that included data from 63,761 adults aged 20-74 y.ResultsAdjusted mean energy intake increased from 1955 kcal/d during 1971-1975 to 2269 kcal/d during 2003-2004 and then declined to 2195 kcal/d during 2009-2010 (P-linear trend < 0.001, P-nonlinear trend < 0.001). During the period from 1999-2000 to 2009-2010, no significant linear trend in energy intake was observed (P = 0.058), but a significant nonlinear trend was noted (P = 0.042), indicating a downward trend in energy intake. Significant decreases in energy intake from 1999-2000 to 2009-2010 were noted for participants aged 20-39 y, men, women, and participants with a BMI (in kg/m(2)) of 18.5 to <25 and ≥30.ConclusionAfter decades of increases, mean energy intake has decreased significantly since 2003-2004.

Project description:Food prices may be one reason for the growing socioeconomic disparities in diet quality.To evaluate the association between diet costs and the Healthy Eating Index-2010 (HEI-2010).Cross-sectional study based on 11,181 adults from the 2007-2010 National Health and Nutrition Examination Survey, analyzed in spring 2014. Diet cost was estimated by linking dietary data with a national food price database. The HEI-2010, a measure of adherence to the dietary guidelines, was the outcome. The population ratio method was used to estimate the average HEI-2010 scores by quintile of energy-adjusted diet cost. Additional analyses evaluated the association between cost and HEI-2010 components.There was a strong positive association between lower energy-adjusted diet costs and lower HEI-2010 scores. The association was stronger among women (p-interaction=0.003). Lower diet costs were associated with lower consumption of vegetables, fruits, whole grains, and seafood, and higher consumption of refined grains and solid fat, alcohol and added sugars.Lower energy-adjusted diet costs were associated with lower-quality diets. Future efforts to improve the nutritional status of the US public should take food prices and diet costs into account.

Project description:BackgroundWhile extensive evidence suggests that the economic recession has had far reaching effects on many economic sectors, little is known regarding its impact on prescription drug utilization. The purpose of this study is to describe the association between state-level unemployment rates and retail sales of seven therapeutic classes (statins, antidepressants, antipsychotics, angiotensin-converting enzyme [ACE] inhibitors, opiates, phosphodiesterase [PDE] inhibitors and oral contraceptives) in the United States.MethodsUsing a retrospective mixed ecological design, we examined retail prescription sales using IMS Health Xponent™ from September 2007 through July 2010, and we used the Bureau of Labor Statistics to derive population-based rates and mixed-effects modeling with state-level controls to examine the association between unemployment and utilization. Our main outcome measure was state-level utilization per 100,000 people for each class.ResultsMonthly unemployment levels and rates of use of each class varied substantially across the states. There were no statistically significant associations between use of ACE inhibitors or SSRIs/SNRIs and average unemployment in analyses across states, while for opioids and PDE inhibitors there were small statistically significant direct associations, and for the remaining classes inverse associations. Analyses using each state as its own control collectively exhibited statistically significant positive associations between increases in unemployment and prescription drug utilization for five of seven areas examined. This relationship was greatest for statins (on average, a 4% increase in utilization per 1% increased unemployment) and PDE inhibitors (3% increase in utilization per 1% increased unemployment), and lower for oral contraceptives and atypical antipsychotics.ConclusionWe found no evidence of an association between increasing unemployment and decreasing prescription utilization, suggesting that any effects of the recent economic recession have been mitigated by other market forces.

Project description:BackgroundLimited nationally representative data are available on dietary supplement (DS) use and resulting nutrient exposures among infants and toddlers.ObjectiveThis study evaluated DS use among US infants and toddlers to characterize DS use, estimate nutrient intake from DSs, and assess trends in DS use over time.MethodsUsing nationally representative data from NHANES (2007-2014) and trends over time (1999-2014), we estimated prevalence of DS use and types of products used for US infants and toddlers aged <2 y (n = 2823). We estimated median daily intakes of vitamins and minerals consumed via DSs for all participants aged <2 y, by age groups (0-11.9 mo and 12.0-23.9 mo), and by feeding practices for infants 0-5.9 mo.ResultsOverall, 18.2% (95% CI: 16.2%, 20.3%) of infants and toddlers used ≥1 DS in the past 30 d. Use was lower among infants (0-5.9 mo: 14.6%; 95% CI: 11.5%, 18.1%; 6-11.9 mo: 11.6%; 95% CI: 8.8%, 15.0%) than among toddlers (12-23.9 mo: 23.3%; 95% CI: 20.4%, 26.3%). The most commonly reported DSs were vitamin D and multivitamin infant drops for those <12 mo, and chewable multivitamin products for toddlers (12-23.9 mo). The nutrients most frequently consumed from DSs were vitamins D, A, C, and E for those <2 y; for infants <6 mo, a higher percentage of those fed breast milk than those fed formula consumed these nutrients via DSs. DS use remained steady for infants (6-11.9 mo) and toddlers from 1999-2002 to 2011-2014, but increased from 7% to 20% for infants aged 0-5.9 mo.ConclusionsOne in 5 infants and toddlers aged <2 y use ≥1 DS. Future studies should examine total nutrient intake from foods, beverages, and DSs to evaluate nutrient adequacy overall and by nutrient source.

Project description:BackgroundArsenic is an ubiquitous element linked to carcinogenicity, neurotoxicity, as well as adverse respiratory, gastrointestinal, hepatic, and dermal health effects.ObjectiveIdentify dietary sources of speciated arsenic: monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA).MethodsAge-stratified, sample-weighted regression of NHANES (National Health and Nutrition Examination Survey) 2003-2010 data (?8,300 participants ?6 years old) characterized the association between urinary arsenic species and the additional mass consumed of USDA-standardized food groups (24-hour dietary recall data), controlling for potential confounders.ResultsFor all arsenic species, the rank-order of age strata for median urinary molar concentration was children 6-11 years > adults 20-84 years > adolescents 12-19 years, and for all age strata, the rank-order was DMA > MMA. Median urinary molar concentrations of methylated arsenic species ranged from 0.56 to 3.52 µmol/mol creatinine. Statistically significant increases in urinary arsenic species were associated with increased consumption of: fish (DMA); fruits (DMA, MMA); grain products (DMA, MMA); legumes, nuts, seeds (DMA); meat, poultry (DMA); rice (DMA, MMA); rice cakes/crackers (DMA, MMA); and sugars, sweets, beverages (MMA). And, for adults, rice beverage/milk (DMA, MMA). In addition, based on US (United States) median and 90th percentile consumption rates of each food group, exposure from the following food groups was highlighted: fish; fruits; grain products; legumes, nuts, seeds; meat, poultry; and sugars, sweets, beverages.ConclusionsIn a nationally representative sample of the US civilian, noninstitutionalized population, fish (adults), rice (children), and rice cakes/crackers (adolescents) had the largest associations with urinary DMA. For MMA, rice beverage/milk (adults) and rice cakes/crackers (children, adolescents) had the largest associations.

Project description:ObjectivesStudies 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.MethodsWe 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.ResultsThe 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.ConclusionsOur results provide population-based evidence that concurrent higher sodium and lower potassium consumption are associated with hypertension.

Project description:ObjectivesWe investigated differences in prevalence of major birth defects by maternal nativity within racial/ethnic groups for 27 major birth defects.MethodsData from 11 population-based birth defects surveillance systems in the United States including almost 13 million live births (approximately a third of U.S. births) during 1999-2007 were pooled. We calculated prevalence estimates for each birth defect for five racial/ethnic groups. Using Poisson regression, crude and adjusted prevalence ratios (aPRs) were also calculated using births to US-born mothers as the referent group in each racial/ethnic group.ResultsApproximately 20% of case mothers and 26% of all mothers were foreign-born. Elevated aPRs for infants with foreign-born mothers were found for spina bifida and trisomy 13, 18, and 21, while lower prevalence patterns were found for pyloric stenosis, gastroschisis, and hypospadias.ConclusionsThis study demonstrates that birth defects prevalence varies by nativity within race/ethnic groups, with elevated prevalence ratios for some specific conditions and lower prevalence for others. More detailed analyses focusing on a broader range of maternal behaviors and characteristics are required to fully understand the implications of our findings.

Project description:To determine the prevalence of gout associated with progressive degrees of kidney disease in the US population.We performed a cross-sectional analysis among non-institutionalized adults (age 20 and older) of the National Health and Nutrition Examination Surveys in 1988-1994 and 2007-2010. Gout status was ascertained by self-report of physician-diagnosed gout. Chronic kidney disease (CKD) was defined in stages based on estimated glomerular filtration rate (GFR) and single albuminuria measurements (albumin-to-creatinine ratio). Prevalence ratios comparing successive categories of GFR, albuminuria, and CKD as well as temporal trends over a 22-year interval were determined via Poisson regression.In the US, the crude prevalence of gout was 2-3% among participants without CKD, 4% among participants with CKD stage 1, 6-10% for stage 2, 11-13% for stage 3, and over 30% for stage 4. The adjusted prevalence ratio comparing the CKD stage 4 stratum to participants without CKD was 3.20 (95% CI: 1.96, 5.24) in 2007-2010 and remained significant even after adjustment for serum uric acid. Notably, there was a statistically significant, progressively greater adjusted prevalence ratio of gout associated with successively lower categories of GFR and higher categories of albuminuria.Among US adults, there exists a strong dose-response association between impaired renal function and prevalent gout. Health providers should be aware of the elevated burden of gout among patients with CKD especially when evaluating new onset joint pain and swelling.

Project description:To determine the association and prevalence of gout among overweight, obese, and morbidly obese segments of the US population.Among participants (age ?20 years) of the National Health and Nutrition Examination Surveys in 1988-1994 and 2007-2010, gout status was ascertained by self-report of a physician diagnosis. Body mass index (BMI) was examined in categories of <18.5 kg/m(2) , 18.5-24.9 kg/m(2) , 25-29.9 kg/m(2) , 30-34.9 kg/m(2) , and ?35 kg/m(2) and as a continuous variable. The cross-sectional association of BMI category with gout status was adjusted for demographic and obesity-related medical disorders.In the US, the crude prevalence of gout was 1-2% among participants with a normal BMI (18.5-24.9 kg/m(2) ), 3% among overweight participants, 4-5% with class I obesity, and 5-7% with class II or class III obesity. The adjusted prevalence ratio comparing the highest to a normal BMI category was 2.46 (95% confidence interval [95% CI] 1.44-4.21) in 1988-1994 and 2.21 (95% CI 1.50-3.26) in 2007-2010. Notably, there was a progressively greater prevalence ratio of gout associated with successively higher categories of BMI. In both survey periods, for an average American adult standing 1.76 meters (5 feet 9 inches), a 1-unit higher BMI, corresponding to 3.1 kg (~6.8 pounds) greater weight, was associated with a 5% greater prevalence of gout, even after adjusting for serum uric acid (P < 0.001).Health care providers should be aware of the elevated burden of gout among both overweight and obese adults, applicable to both women and men, and observed among non-Hispanic whites, non-Hispanic African Americans, and Mexican Americans in the US.
