Potential population-level nutritional impact of replacing whole and reduced-fat milk with low-fat and skim milk among US children aged 2-19 years.
OBJECTIVE: Dietary guidance emphasizes plain low-fat and skim milk over whole, reduced-fat, and flavored milk (milk eligible for replacement [MER]). The objective of this study was to evaluate the population-level impact of such a change on energy, macronutrient and nutrient intakes, and diet cost. DESIGN: Cross-sectional modeling study. SETTING: Data from the 2001-2002 and 2003-2004 National Health and Nutrition Examination Survey. PARTICIPANTS: A total of 8,112 children aged 2-19 years. MAIN OUTCOME MEASURES: Energy, macronutrient, and micronutrient intake before and after replacement of MER with low-fat or skim milk. ANALYSIS: Survey-weighted linear regression models. RESULTS: Milk eligible for replacement accounted for 46% of dairy servings. Among MER consumers, replacement with skim or low-fat milk would lead to a projected reduction in energy of 113 (95% confidence interval [CI], 107-119) and 77 (95% CI, 73-82) kcal/d and percent energy from saturated fat by an absolute value of 2.5% of total energy (95% CI, 2.4-2.6) and 1.4% (95% CI, 1.3-1.5), respectively. Replacement of MER does not change diet costs or calcium and potassium intake. CONCLUSIONS: Substitution of MER has the potential to reduce energy and total and saturated fat intake with no impact on diet costs or micronutrient density. The feasibility of such replacement has not been examined and there may be negative consequences if replacement is done with non-nutrient-rich beverages.This research was commissioned by

Water and beverage consumption among children age 4-13y in the United States: analyses of 2005–2010 NHANES data
BACKGROUND: Few studies have examined water consumption patterns among US children. Additionally, recent data on total water consumption as it relates to the Dietary Reference Intakes (DRI) are lacking. This study evaluated the consumption of plain water (tap and bottled) and other beverages among US children by age group, gender, income-to-poverty ratio, and race/ethnicity. Comparisons were made to DRI values for water consumption from all sources. METHODS: Data from two non-consecutive 24-hour recalls from 3 cycles of NHANES (2005–2006, 2007–2008 and 2009–2010) were used to assess water and beverage consumption among 4,766 children age 4-13y. Beverages were classified into 9 groups: water (tap and bottled), plain and flavored milk, 100% fruit juice, soda/soft drinks (regular and diet), fruit drinks, sports drinks, coffee, tea, and energy drinks. Total water intakes from plain water, beverages, and food were compared to DRIs for the US. Total water volume per 1,000 kcal was also examined. RESULTS: Water and other beverages contributed 70-75% of dietary water, with 25-30% provided by moisture in foods, depending on age. Plain water, tap and bottled, contributed 25-30% of total dietary water. In general, tap water represented 60% of drinking water volume whereas bottled water represented 40%. Non-Hispanic white children consumed the most tap water, whereas Mexican-American children consumed the most bottled water. Plain water consumption (bottled and tap) tended to be associated with higher incomes. No group of US children came close to satisfying the DRIs for water. At least 75% of children 4-8y, 87% of girls 9-13y, and 85% of boys 9-13y did not meet DRIs for total water intake. Water volume per 1,000 kcal, another criterion of adequate hydration, was 0.85-0.95 L/1,000 kcal, short of the desirable levels of 1.0-1.5 L/1,000 kcal. CONCLUSIONS: Water intakes at below-recommended levels may be a cause for concern. Data on water and beverage intake for the population and by socio-demographic group provides useful information to target interventions for increasing water intake among children
Arterial roads and area socioeconomic status are predictors of fast food restaurant density in King County, WA
<p>Abstract</p> <p>Background</p> <p>Fast food restaurants reportedly target specific populations by locating in lower-income and in minority neighborhoods. Physical proximity to fast food restaurants has been associated with higher obesity rates.</p> <p>Objective</p> <p>To examine possible associations, at the census tract level, between area demographics, arterial road density, and fast food restaurant density in King County, WA, USA.</p> <p>Methods</p> <p>Data on median household incomes, property values, and race/ethnicity were obtained from King County and from US Census data. Fast food restaurant addresses were obtained from Public Health-Seattle & King County and were geocoded. Fast food density was expressed per tract unit area and per capita. Arterial road density was a measure of vehicular and pedestrian access. Multivariate logistic regression models containing both socioeconomic status and road density were used in data analyses.</p> <p>Results</p> <p>Over one half (53.1%) of King County census tracts had at least one fast food restaurant. Mean network distance from dwelling units to a fast food restaurant countywide was 1.40 km, and 1.07 km for census tracts containing at least one fast food restaurant. Fast food restaurant density was significantly associated in regression models with low median household income (p < 0.001) and high arterial road density (p < 0.001) but not with percent of residents who were nonwhite.</p> <p>Conclusion</p> <p>No significant association was observed between census tract minority status and fast food density in King County. Although restaurant density was linked to low household incomes, that effect was attenuated by arterial road density. Fast food restaurants in King County are more likely to be located in lower income neighborhoods and higher traffic areas.</p
The feasibility of meeting the WHO guidelines for sodium and potassium: a cross-national comparison study.
OBJECTIVE: To determine joint compliance with the WHO sodium-potassium goals in four different countries, using data from nationally representative dietary surveys. SETTING: Compared to national and international recommendations and guidelines, the world's population consumes too much sodium and inadequate amounts of potassium. The WHO recommends consuming less than 2000 mg sodium (86 mmol) and at least 3510 mg potassium (90 mmol) per person per day. PARTICIPANTS: Dietary surveillance data were obtained from the National Health and Nutrition Examination Survey (NHANES 2007-2010) for the USA; the Encuesta Nacional de Salud y Nutrición 2012 for Mexico; the Individual and National Study on Food Consumption (INCA2) for France; and the National Diet and Nutrition Survey (NDNS) for the UK. PRIMARY OUTCOME MEASURES: We estimated the proportion of adults meeting the joint WHO sodium-potassium goals in the USA, the UK, France and Mexico. RESULTS: The upper bounds of joint compliance with the WHO sodium-potassium goals were estimated at 0.3% in the USA, 0.15% in Mexico, 0.5% in France and 0.1% in the UK. CONCLUSIONS: Given prevailing food consumption patterns and the current food supply, implementing WHO guidelines will be an enormous challenge for global public health.Supported by NIH grants R01 DK 077068-04 and R21 DK085406This is the final version.

Regional contributions of six preventable risk factors to achieving the 25 × 25 non-communicable disease mortality reduction target: a modelling study
Background Countries have agreed to reduce premature mortality from the four main non-communicable diseases
(NCDs) by 25% from 2010 levels by 2025 (referred to as the 25 × 25 target). Countries also agreed on a set of global
voluntary targets for selected NCD risk factors. Previous analyses have shown that achieving the risk factor targets can
contribute substantially towards meeting the 25 × 25 mortality target at the global level. We estimated the contribution
of achieving six of the globally agreed risk factor targets towards meeting the 25 × 25 mortality target by region.
Methods We estimated the eff ect of achieving the targets for six risk factors (tobacco and alcohol use, salt intake,
obesity, and raised blood pressure and glucose) on NCD mortality between 2010 and 2025. Our methods accounted
for multicausality of NCDs and for the fact that, when risk factor exposure increases or decreases, the harmful or
benefi cial eff ects on NCDs accumulate gradually. We used data for risk factor and mortality trends from systematic
analyses of available country data. Relative risks for the eff ects of individual and multiple risks, and for change in risk
after decreases or increases in exposure, were from reanalyses and meta-analyses of epidemiological studies.
Findings The probability of dying between the ages 30 years and 70 years from the four main NCDs in 2010 ranged
from 19% in the region of the Americas to 29% in southeast Asia for men, and from 13% in Europe to 21% in
southeast Asia for women. If current trends continue, the probability of dying prematurely from the four main NCDs
is projected to increase in the African region but decrease in the other fi ve regions. If the risk factor targets are
achieved, the 25 × 25 target will be surpassed in Europe in both men and women, and will be achieved in women (and
almost achieved in men) in the western Pacifi c; the regions of the Americas, the eastern Mediterranean, and southeast
Asia will approach the target; and the rising trend in Africa will be reversed. In most regions, a more ambitious
approach to tobacco control (50% reduction relative to 2010 instead of the agreed 30%) will contribute the most to
reducing premature NCD mortality among men, followed by addressing raised blood pressure and the agreed tobacco
target. For women, the highest contributing risk factor towards the premature NCD mortality target will be raised
blood pressure in every region except Europe and the Americas, where the ambitious (but not agreed) tobacco
reduction would have the largest benefi t.
Interpretation No WHO region will meet the 25 × 25 premature mortality target if current mortality trends continue.
Achieving the agreed targets for the six risk factors will allow some regions to meet the 25 × 25 target and others to
approach it. Meeting the 25 × 25 target in Africa needs other interventions, including those addressing infectionrelated
cancers and cardiovascular disease

Preventable Cancer Burden Associated With Poor Diet in the United States.
BACKGROUND: Diet is an important risk factor for cancer that is amenable to intervention. Estimating the cancer burden associated with diet informs evidence-based priorities for nutrition policies to reduce cancer burden in the United States. METHODS: Using a comparative risk assessment model that incorporated nationally representative data on dietary intake, national cancer incidence, and estimated associations of diet with cancer risk from meta-analyses of prospective cohort studies, we estimated the annual number and proportion of new cancer cases attributable to suboptimal intakes of seven dietary factors among US adults ages 20 years or older, and by population subgroups. RESULTS: An estimated 80 110 (95% uncertainty interval [UI] = 76 316 to 83 657) new cancer cases were attributable to suboptimal diet, accounting for 5.2% (95% UI = 5.0% to 5.5%) of all new cancer cases in 2015. Of these, 67 488 (95% UI = 63 583 to 70 978) and 4.4% (95% UI = 4.2% to 4.6%) were attributable to direct associations and 12 589 (95% UI = 12 156 to 13 038) and 0.82% (95% UI = 0.79% to 0.85%) to obesity-mediated associations. By cancer type, colorectal cancer had the highest number and proportion of diet-related cases (n = 52 225, 38.3%). By diet, low consumption of whole grains (n = 27 763, 1.8%) and dairy products (n = 17 692, 1.2%) and high intake of processed meats (n = 14 524, 1.0%) contributed to the highest burden. Men, middle-aged (45-64 years) and racial/ethnic minorities (non-Hispanic blacks, Hispanics, and others) had the highest proportion of diet-associated cancer burden than other age, sex, and race/ethnicity groups. CONCLUSIONS: More than 80 000 new cancer cases are estimated to be associated with suboptimal diet among US adults in 2015, with middle-aged men and racial/ethnic minorities experiencing the largest proportion of diet-associated cancer burden in the United States.This work was supported by NIH/ NIMHD 1R01MD011501 (FFZ), NIH/ NHLBI R01HL115189 (DM), United Kingdom Medical Research Council Epidemiology Unit Core Support (MC_UU_12015/5) (FI), and American Heart Association postdoctoral fellowship (JXL)
Reductions in national cardiometabolic mortality achievable by food price changes according to Supplemental Nutrition Assistance Program (SNAP) eligibility and participation
Background: Suboptimal diets are a major contributor to cardiometabolic disease (CMD) mortality, and substantial disparities exist for both dietary quality and mortality risk across income groups in the USA. Research is needed to quantify how food pricing policies to subsidise healthy foods and tax unhealthy foods could affect the US CMD mortality, overall and by Supplemental Nutrition Assistance Program (SNAP) eligibility and participation. Methods: Comparative risk analysis based on national data on diet (National Health and Nutrition Examination Survey, 2003–2012) and mortality (mortality-linked National Health Interview Survey) and meta-analyses of policy-diet and diet-disease relationships. Results: A national 10% price reduction on fruits, vegetables, nuts and whole grains was estimated to prevent 19 600 CMD deaths/year, including 2.6% (95% UI 2.4% to 2.8%) of all CMD deaths among SNAP participants, 2.7% (95% UI 2.4% to 3.0%) among SNAP-eligible non-participants and 2.6% (95% UI 2.4% to 2.8%) among SNAP-ineligible non-participants. Adding a national 10% tax on sugar-sweetened beverages (SSBs) and processed meats would prevent a total of 33 700 CMD deaths/year, including 5.9% (95% UI 5.4% to 7.4%) of all CMD deaths among SNAP participants, 4.8% (95% UI 4.4% to 5.2%) among SNAP-eligible non-participants and 4.1% (95% UI 3.8% to 4.5%) among SNAP-ineligible non-participants. Adding a SNAP-targeted 30% subsidy for the same healthy foods would offer the largest reductions in both CMD mortality and disparities. Conclusion: National subsidies for healthy foods and taxes on SSBs and processed meats would each reduce CMD mortality; taxes would also reduce CMD mortality more steeply for SNAP participants than for non-participants
The Effectiveness of Alcohol Screening and Brief Intervention in Emergency Departments: A Multicentre Pragmatic Cluster Randomized Controlled Trial
BACKGROUND:
Alcohol misuse is common in people attending emergency departments (EDs) and there is some evidence of efficacy of alcohol screening and brief interventions (SBI). This study investigated the effectiveness of SBI approaches of different intensities delivered by ED staff in nine typical EDs in England: the SIPS ED trial.
METHODS AND FINDINGS:
Pragmatic multicentre cluster randomized controlled trial of SBI for hazardous and harmful drinkers presenting to ED. Nine EDs were randomized to three conditions: a patient information leaflet (PIL), 5 minutes of brief advice (BA), and referral to an alcohol health worker who provided 20 minutes of brief lifestyle counseling (BLC). The primary outcome measure was the Alcohol Use Disorders Identification Test (AUDIT) status at 6 months. Of 5899 patients aged 18 or more presenting to EDs, 3737 (63·3%) were eligible to participate and 1497 (40·1%) screened positive for hazardous or harmful drinking, of whom 1204 (80·4%) gave consent to participate in the trial. Follow up rates were 72% (n?=?863) at six, and 67% (n?=?810) at 12 months. There was no evidence of any differences between intervention conditions for AUDIT status or any other outcome measures at months 6 or 12 in an intention to treat analysis. At month 6, compared to the PIL group, the odds ratio of being AUDIT negative for brief advice was 1·103 (95% CI 0·328 to 3·715). The odds ratio comparing BLC to PIL was 1·247 (95% CI 0·315 to 4·939). A per protocol analysis confirmed these findings.
CONCLUSIONS:
SBI is difficult to implement in typical EDs. The results do not support widespread implementation of alcohol SBI in ED beyond screening followed by simple clinical feedback and alcohol information, which is likely to be easier and less expensive to implement than more complex interventions
Linked randomised controlled trials of face-to-face and electronic brief intervention methods to prevent alcohol related harm in young people aged 14–17 years presenting to Emergency Departments (SIPS junior)
Background: Alcohol is a major global threat to public health. Although the main burden of chronic alcohol-related disease is in adults, its foundations often lie in adolescence. Alcohol consumption and related harm increase steeply from the age of 12 until 20 years. Several trials focusing upon young people have reported significant positive effects of brief interventions on a range of alcohol consumption outcomes. A recent review of reviews also suggests that electronic brief interventions (eBIs) using internet and smartphone technologies may markedly reduce alcohol consumption compared with minimal or no intervention controls.
Interventions that target non-drinking youth are known to delay the onset of drinking behaviours. Web based alcohol interventions for adolescents also demonstrate significantly greater reductions in consumption and harm among ‘high-risk’ drinkers; however changes in risk status at follow-up for non-drinkers or low-risk
drinkers have not been assessed in controlled trials of brief alcohol interventions
