ABSTRACT: Introduction
In the U.S., there is no consensus of how to define junk food. Strict regulations on what constitutes junk food denoted by front-of-package labels can serve as the basis for statutory actions. Chile was the first country to adopt this approach, and several countries have followed suit. This study examined the proportion of calories and nutrients of concern consumed by U.S. children and adolescents defined as junk food using the Chilean label criteria and the changes between 2003 and 2016.Methods
Data were obtained from 4 nationally representative food intake surveys in 13,016 U.S. children and adolescents: National Health and Nutrition Examination Survey 2003-2004, 2005-2006, 2013-2014, and 2015-2016, with analysis performed in 2019. Nutritional content of each consumed food was compared with nutrient thresholds from the Chilean regulation for energy, saturated fat, total sugars, and sodium per 100 g.Results
Between 2003 and 2016, there was a 10 percentage point decrease (71.1%-61.3%, p<0.01) in the proportion of foods consumed that were classified as junk food. A significant decrease was seen in mean intake of calories (1,610-1,367 kcal/day, p<0.01), total sugar (88.8-64.2 g/day, p<0.01), saturated fat (22.6-20.5 g/day, p<0.01), and sodium (2,306-2,044 mg/day, p<0.01).Conclusions
Although junk food intake has decreased since 2003-2006, diets of U.S. children and adolescents remain dominated by less-healthy foods. These results can help guide policy regulations regarding foods and beverages accessible in schools and marketed to children, adolescents, and their caregivers.

Project description:Physicians and policy makers are increasingly interested in caffeine intake among children and adolescents in the advent of increasing energy drink sales. However, there have been no recent descriptions of caffeine or energy drink intake in the United States. We aimed to describe trends in caffeine intake over the past decade among US children and adolescents.We assessed trends and demographic differences in mean caffeine intake among children and adolescents by using the 24-hour dietary recall data from the 1999-2010 NHANES. In addition, we described the proportion of caffeine consumption attributable to different beverages, including soda, energy drinks, and tea.Approximately 73% of children consumed caffeine on a given day. From 1999 to 2010, there were no significant trends in mean caffeine intake overall; however, caffeine intake decreased among 2- to 11-year-olds (P < .01) and Mexican-American children (P = .003). Soda accounted for the majority of caffeine intake, but this contribution declined from 62% to 38% (P < .001). Coffee accounted for 10% of caffeine intake in 1999-2000 but increased to nearly 24% of intake in 2009-2010 (P < .001). Energy drinks did not exist in 1999-2000 but increased to nearly 6% of caffeine intake in 2009-2010.Mean caffeine intake has not increased among children and adolescents in recent years. However, coffee and energy drinks represent a greater proportion of caffeine intake as soda intake has declined. These findings provide a baseline for caffeine intake among US children and young adults during a period of increasing energy drink use.

Project description:Over the past decade, blood pressure and sodium intake declined among children and adolescents (ie, youths) in the United States. We updated temporal trends and determined if secular changes in blood pressure might be partly associated with usual sodium intake. We included 12 249 youths aged 8 to 17 years who participated in the National Health and Nutrition Examination Survey from 2003 to 2016 and had blood pressure and dietary data. Logistic regression was used to describe secular trends and the association between usual sodium intake and blood pressure categorized according to 2017 Hypertension Guidelines. The prevalence of youths with combined elevated blood pressure/hypertension (ie, either elevated blood pressure or hypertension) significantly declined from 16.2% in 2003-2004 to 13.3% in 2015-2016 ( P<0.001 for trend), as did hypertension from 6.6% to 4.9% ( P=0.005 for trend). Across the same time period, mean usual sodium intake decreased from 3381 to 3208 mg/day ( P<0.001 for trend). Holding constant survey cycle, sex, age, race and Hispanic origin, and weight status, the adjusted odds ratio per 1000 mg/day of usual sodium intake for elevated blood pressure/hypertension was 1.18 (95% CI, 1.03-1.35) and for hypertension was 1.20 (95% CI, 0.96-1.50). From 2003 to 2016, blood pressure and usual sodium intake declined among youths. Although 1000 mg/day higher usual sodium intake was associated with ≈20% higher odds of elevated blood pressure/hypertension and hypertension, the association with hypertension was not statistically significant.

Project description:Trend analyses suggest that free sugar (FS) intake-while still exceeding 10%E-has decreased among German children and adolescents since 2005, yet that intakes may shift from sugars naturally occurring in foods to added sugars as children age. Thus, we analysed time and age trends in FS intake (%E) from food groups among 3-18 year-olds (1985-2016) using 10,761 3-day dietary records from 1312 DONALD participants (660 boys, 652 girls) by use of polynomial mixed-effects regression models. Among girls, FS from sugar & sweets decreased from 1985 to 2016 (linear trend p < 0.0001), but not among boys (p > 0.05). In the total sample, FS intake from juices increased until 2000 and decreased since 2005 (linear, quadratic trend p < 0.0001). FS from sugar sweetened beverages (SSB) decreased non-linearly from 1985 to 2016 (girls: linear, quadratic, cubic trend p < 0.0001; boys: linear, quadratic, cubic trend p < 0.02). Younger children consumed more FS from juices than older ones, who had a higher FS intake from SSB. FS intake from sugar & sweets increased until early adolescence and decreased afterwards. Since sugar & sweets represent the main source of FS intake and the source with the least pronounced decline in intake, public health measures should focus on these products.

Project description:BackgroundTrends in junk food consumption, a risk for obesity, are not well established.ObjectivesWe examined national trends in types of junk food (excluding beverages) and their sources (grocery, restaurants, schools, etc.), overall and in population subgroups.MethodsWe assessed 29,970 children (aged 2-19 y) and 44,501 adults (aged ≥20 y) with 24-h dietary recall data from 9 NHANES cycles (2001-2002 to 2017-2018). Trends in junk food were assessed over time using 1-d values for individuals with single recalls and 2-d means for others.ResultsFrom 2001 to 2018, percent energy (%E) from junk food remained stable for children (from 18.1% to 17.5%, P-trend = 0.25) and decreased for adults (14.1% to 13.0%, P-trend = 0.002). Among children, increases occurred in %E from crackers (1.19% to 1.35%) and snack/meal bars (0.38% to 0.69%) and decreases in candy (2.58% to 1.96%) and other desserts (3.11% to 2.48%) (all P-trends < 0.01). Among adults, increases occurred in snack/meal bars (0.31% to 0.78%, P-trend < 0.001) and decreases in candy (1.97% to 1.55%; P-trend < 0.001), sweet bakery products (5.52% to 4.98%; P-trend = 0.04), and other desserts (2.19% to 1.86%; P-trend = 0.001). In 2017-2018, grocery stores provided the largest proportion of junk food (72.7% for children, 77.1% for adults), followed by other sources (13.1%, 12.1%), restaurants (8.05%, 9.11%), schools (4.86%), and worksites (1.99%). In both children and adults, junk food intake was higher among non-Hispanic white and black Americans compared with Mexican Americans, among those with higher compared with lower education, among women compared with men, and among older compared with younger adults. In sensitivity analyses using only 1-d recalls, mean junk food intake each cycle was ∼0.8-1.0 and 0.3-0.4%E units higher in children and adults, respectively, with otherwise similar trends and subgroup differences over time.ConclusionsFrom 2001 to 2018, %E from junk food represented nearly 1 in 5 calories among children, without change, and nearly 1 in 7 calories, with modest decrease, among adults, with disparities in subgroups.

Project description:Objective: Food insecurity has been linked to adverse health consequences. We sought to determine if food insecurity was related to obesity and prediabetes risk in U.S. adolescents. We also investigated if Supplemental Nutrition Assistance Program (SNAP) utilization mitigated any observed risks. Materials and Methods: We used linear and logistic regression analysis of cross-sectional data from a nationally representative sample of U.S. adolescents aged 12-19 years participating in the National Health And Nutrition Examination Survey 2003-2014 who had an income:poverty ratio of <5.0 and had complete data regarding metabolic laboratory assessments, food security, and socioeconomic status (n = 2662). Results: Food insecurity was present in 18.40% (95% confidence interval (CI): 16.47-20.37) among U.S. adolescents meeting inclusion criteria. Food insecurity was associated with increased odds of elevated blood pressure (adjusted odds ratio [aOR] = 1.57, 95% CI: 1.11-2.22) and prediabetes (aOR = 1.94, 95% CI: 1.16-3.25). SNAP usage was associated with higher body mass index z-score (e.g., mean: 0.80 vs. 0.59, P = 0.02), increased insulin resistance, and increased prediabetes odds among food-secure adolescents relative to nonusage. Conclusions: Food insecurity is relatively prevalent among U.S. adolescents with an income:poverty ratio of <5.0. Food insecurity is related to laboratory abnormalities and corresponding adverse health outcomes among U.S. adolescents in this relatively large sample. SNAP usage was associated with adverse health observations among food-secure adolescents. Ongoing efforts are still needed toward food assistance as important public health efforts aimed at mitigating the adverse outcomes related to food insecurity.

Project description:BACKGROUND:It has been previously reported that total energy intake among US preschool children (ages 2-5 years) decreased between 2003-2004 and 2009-2010. However, little is known about how intakes of beverages among US preschoolers (ages 2-5 years) changed from 2003-2004 to 2011-2012. OBJECTIVES:This paper examines changes in intakes of key beverages during this period, as well as how eating location (at home or away from home) and source (store vs. others) may have contributed to these changes. METHODS:Cross-sectional day one dietary data among children ages 2-5 years from the National Health and Nutrition Examination Survey 2003-2004, 2005-2006, 2007-2008, 2009-2010 and 2011-2012 were used. Survey-weighted mean intakes by survey year, eating location and source were computed for total sugar-sweetened beverages (SSBs), milks, 100% juice, low/no-calorie beverages, 10 key beverages, total beverages and total foods. Means were compared using two-tailed z-tests with Bonferroni corrections (??<?0.05). RESULTS:Between 2003-2004 and 2011-2012, among 2-5 year olds, total caloric intake fell by 132?kcal?d(-1) , with intakes of beverages falling by 55?kcal?d(-1) . Decreases in intakes of total SSBs (-57?kcal?d(-1) ), fruit-flavoured or juice drinks containing <100% juice (juice drinks) (-37?kcal?d(-1) ), caloric soft drinks (-13?kcal?d(-1) ) and >1% fat, low-sugar milk (-42?kcal?d(-1) ) were among the major changes. By eating location, total beverage intake at home fell by 73?kcal?d(-1) . By source, total beverage intake from stores fell by 106?kcal?d(-1) . Changes in intakes occurred primarily between 2003-2004 and 2009-2010, as there were no significant differences in beverage intakes between 2009-2010 and 2011-2012. Intakes of total calories (+49?kcal?d(-1) ) and calories from foods (+53?kcal?d(-1) ) trended upward between 2009-2010 and 2011-2012, but changes were not significant. CONCLUSIONS:These findings suggest improvements in the diets of preschoolers between 2003-2004 and 2009-2010, of which stores were a major contributor.

Project description:BackgroundThere is no consensus on how to define "junk food." In 2016, Chile implemented the most comprehensive set of obesity-preventive regulations in the world, including criteria to define unhealthy foods.ObjectivesThe objective of this study was to examine the amount of energy, sodium, sugar, and saturated fat consumed by US adults defined as junk food using the Chilean criteria.MethodsWe used 2 nationally representative surveys of food intake in 10,001 US adults: NHANES 2015-2016 and NHANES 2017-2018. The main outcome measures were the contributions of energy, total sugars, saturated fat, and sodium deriving from junk food sources. Mean intake and proportion of energy, sugar, saturated fat, and sodium for junk food overall and each food category were calculated.ResultsOverall, 47% of energy, 75% of total sugar, 46% of sodium, and 48% of saturated fat consumed by US adults derived from junk food sources. Sugar-sweetened beverages (SSBs) were responsible for more than 40% of total sugar intake deriving from junk foods. Non-Hispanic black adults had the highest mean energy, total sugar, and sodium intake deriving from junk foods, with non-Hispanic white adults having the highest saturated fat intake. Non-Hispanic black adults had the highest intake of total sugar deriving from junk food sources of SSBs (26.7 g/d), with SSBs representing >40% of total sugar intake deriving from junk food sources for all race/ethnic groups.ConclusionsFoods that meet the Chilean criteria for junk food provide approximately half or more daily energy and food components to limit in the diet of US adults, with important differences observed between race/ethnic groups. Policy efforts to reduce junk food intake, particularly the intake of SSBs, must be expanded to improve the cardiometabolic health equitably in the United States.

Project description:Consumption of sugar-sweetened beverages (SSBs) increases total caloric intake, is linked to cardiometabolic outcomes as well as dental caries, and sugar in SSBs is associated with mortality and frailty among adults. We describe energy and total sugar intake trends among the United States (US) population from SSBs, soft drinks, other beverage groups, and the total diet based on the first 24-h recall data from the National Health and Nutrition Examination Survey (NHANES) cycles (2003-2004 through 2015-2016). SSBs included soft drinks, sports drinks, energy drinks, and fruit drinks, but excluded sports beverages with protein and sweetened teas/coffees. Among the total population (age ?2 years: 57,026), energy intake from SSBs declined significantly from 183.9 ± 6.9 mean kcal/d (±SE) in 2003-2004 to 95.0 ± 3.5 in 2015-2016, while total sugar intake declined from 43.6 ± 1.7 mean g/d to 22.3 ± 0.8 (p-trend < 0.0001). Decreases were found for energy and total sugar intake, as well as percentage of energy and total sugar intake from SSBs, soft drinks, and all beverages for all age groups examined (?2, 2-19, ?20 years) (p-trend < 0.0001). From 2003 to 2016, energy and sugar intake from all beverages, SSBs, soft drinks, and the total diet decreased among the total population, children, and adults.

Project description:BackgroundPhthalates and bisphenol A (BPA) are widely used industrial chemicals that may adversely impact human health. Human exposure is ubiquitous and can occur through diet, including consumption of processed or packaged food.ObjectiveTo examine associations between recent fast food intake and BPA and urinary metabolites of di(2-ethylhexyl) phthalate (?DEHPm) and diisononyl phthalate (DiNPm) among the U.S.PopulationMethodsWe combined data on 8,877 participants from the National Health and Nutrition Examination Survey (NHANES 2003-2010). Using 24-hr dietary recall data, we quantified: a) fast food intake [percent of total energy intake (TEI) from fast food]; b) fast food-derived fat intake (percent of TEI from fat in fast food); and c) fast food intake by food group (dairy, eggs, grains, meat, and other). We examined associations between dietary exposures and urinary chemical concentrations using multivariate linear regression.ResultsWe observed evidence of a positive, dose-response relationship between fast food intake and exposure to phthalates (p-trend < 0.0001) but not BPA; participants with high consumption (? 34.9% TEI from fast food) had 23.8% (95% CI: 11.9%, 36.9%) and 39.0% (95% CI: 21.9%, 58.5%) higher levels of ?DEHPm and DiNPm, respectively, than nonconsumers. Fast food-derived fat intake was also positively associated with ?DEHPm and DiNPm (p-trend < 0.0001). After adjusting for other food groups, ?DEHPm was associated with grain and other intake, and DiNPm was associated with meat and grain intake.ConclusionFast food may be a source of exposure to DEHP and DiNP. These results, if confirmed, could inform individual and regulatory exposure reduction strategies.CitationZota AR, Phillips CA, Mitro SD. 2016.

Project description:Recent national surveys suggest that child obesity in the United States may have reached a plateau, but corresponding trends in energy intake have not been examined in depth. This article evaluates medium-term trends in children's reported energy intake by using 4 waves of national dietary surveillance from 2003-2004 to 2009-2010. The analysis uses up to 2 24-h dietary recalls, incorporating methods that address challenges in estimating usual intake, accounting for intraindividual variance and covariates such as the presence of atypical consumption days. Quantile regression was used to assess disparities in intake among sociodemographic subgroups at extremes of the distribution as well as at the median, and the potential influence of misreporting was evaluated. Results indicated that after an initial decline in intakes across all age groups through 2007-2008, there were significant increases of ∼90 kcal/d at the median among adolescents in 2009-2010, whereas intakes in younger children remained steady. Among adolescent boys, the recent increase was larger at the 90th percentile than at the median. Intake trends did not vary by race/ethnic group, among whom intakes were similar at the upper end of the distribution. Misreporting did not influence trends over time, but intakes were lower in younger children and higher in older children after excluding misreporters. Overall, findings suggest that declines in children's energy intake from 2003-2004 through 2007-2008 were consistent with the obesity plateau observed in most age and gender subgroups through 2009-2010. However, there is evidence of increased intakes among adolescents in 2009-2010, which may threaten the earlier abatement in overweight in this older age group.
