We examined associations between sugar-sweetened beverage (SSB) intake - a chronic disease risk factor - and characteristics of 75,029 adults (≥18 y) in 9 states by using 2016 Behavioral Risk Factor Surveillance System (BRFSS) data. We used multinomial logistic regression to estimate adjusted odds ratios for SSB intake categorized as none (reference), fewer than 1 time per day, and 1 or more times per day, by sociodemographic and behavioral characteristics. Overall, 32.1% of respondents drank SSBs 1 or more times per day. We found higher odds for 1 or more times per day among younger respondents, men, Hispanic and non-Hispanic black respondents, current smokers, respondents residing in nonmetropolitan counties, employed respondents, and those with less than high school education, obesity, and no physical activity. Our findings can inform the targeting of efforts to reduce SSB consumption.

Purpose: To examine associations of adolescent sugar-sweetened beverage (SSB) intake with parent SSB intake and parent and adolescent knowledge of SSB-related health risks., Design: Quantitative, cross-sectional., Setting: 2014 SummerStyles survey., Subjects: Nine hundred and ninety parent and adolescent (12-17 years) pairs., Measures: The outcome was self-reported adolescent intake (0, >0 to <1, or ≥1 time/day) of SSBs (soda, fruit drinks, sports/energy drinks, other SSBs). The exposures were self-reported parent SSB intake (0, >0 to <1, ≥1 to <2, or ≥2 times/day) and parent and adolescent knowledge of SSB-related health risks (weight gain, diabetes, and dental caries)., Analysis: Separate multinomial logistic regression models were used to estimate adjusted odds ratios (aORs) for adolescent SSB intake ≥1 time/day (ref: 0 times/day), according to (1) parent SSB intake and (2) parent and (3) adolescent knowledge., Results: About 31% of adolescents consumed SSBs ≥1 time/day, and 43.2% of parents consumed SSBs ≥2 times/day. Adolescent and parent knowledge that SSB intake is related to health conditions ranged from 60.7% to 80.4%: weight gain (75.0% and 80.4%, respectively), diabetes (60.7% and 71.4%, respectively), and dental caries (77.5% and 72.9%, respectively). In adjusted models, adolescent SSB intake ≥1 time/day was associated with parent intake ≥2 times/day (aOR = 3.30; 95% confidence interval = 1.62-6.74) but not with parent or adolescent knowledge of health risks., Conclusion: Parental SSB intake may be an important factor in understanding adolescent behavior; knowledge of SSB-related health conditions alone may not influence adolescent SSB behavior.

Purpose: To compare the performance of a 1-question survey screener measuring total sugar-sweetened beverage (SSB) intake to a screener measuring SSB types separately using 4 questions., Design: Cross-sectional., Setting: Web-based 2014 SummerStyles survey., Participants: A total of 4167 US adults (≥18 years)., Measures: Frequency of SSB intake measured using a 1-question screener was compared to frequency using a 4-question screener (regular soda, fruit drinks, sports/energy drinks, sweetened coffee/tea). SSB intake (number of time/day) was categorized as 0, >0 to <1, and ≥1 time/day; difference in mean intake was calculated between 4 questions versus 1., Analysis: Paired t tests were used, and agreement was evaluated using weighted κ and Lin's concordance correlation coefficient (CCC)., Results: Mean SSB intake was 1.7 (95% confidence interval [CI]: 1.65-1.79) times/day using 4 questions and 0.6 (95% CI: 0.56-0.62) times/day using 1 question ( P < .001). Intake frequency based on 4 questions versus 1 was 16.0% versus 38.5% for 0 time/day, 15.6% versus 42.5% for >0 to <1 time/day, and 68.4% versus 18.9% for ≥1 time/day. There was fair agreement for the 3 SSB intake categories (κ: .27) and poor absolute agreement between the 2 continuous measures (Lin's CCC: 0.31)., Conclusion: Daily SSB intake was significantly lower using a 1-question screener versus a 4-question screener. Researchers should assess SSB types separately or consider that daily SSB intake is likely underestimated with 1 question.

Purpose: This study examined associations between knowledge of sugar-sweetened beverage (SSB)-related health conditions and SSB intake among US adults., Design: Quantitative, cross-sectional study., Subject: The 2014 SummerStyles survey data for 4163 US adults (≥18 years) were used., Measures: The outcome measure was frequency of SSB intake (regular soda, fruit drinks, sports or energy drinks, sweetened coffee/tea drinks). Exposure measures were knowledge of 6 SSB-related health conditions: weight gain, diabetes, cavities, high cholesterol, heart disease, and hypertension., Analysis: Six logistic regression models were used to estimate adjusted odds ratios (ORs) for consuming SSBs ≥2 times/d according to knowledge of SSB-related health conditions., Results: Overall, 37.8% of adults reported consuming SSBs ≥2 times/d. Although most adults identified that weight gain (80.2%), diabetes (73.6%), and cavities (71.8%) are related to drinking SSBs, fewer adults identified high cholesterol (24.1%), heart disease (31.5%), and hypertension (33.0%) as being related to drinking SSBs. Crude analyses indicated that lower SSB intake was significantly associated with knowledge of the associations between SSBs and weight gain, diabetes, cavities, and heart disease. However, after adjustment for covariates, only lack of knowledge of the association between heart disease and SSBs was significantly associated with consuming SSBs ≥2 times/d (OR = 1.29) than non-SSB consumers., Conclusions: The finding that knowledge of SSB-related health conditions, in general, was not associated with high SSB intake suggests that knowledge on SSB-related health conditions alone may not be sufficient for adult behavior change.

The 2015-2020 Dietary Guidelines for Americans recommend that the daily intake of calories from added sugars not exceed 10% of total calories. Sugar-sweetened beverages (SSBs) are significant sources of added sugars in the diet of U.S. adults and account for approximately one third of added sugar consumption. Among adults, frequent (i.e., at least once a day) SSB intake is associated with adverse health consequences, including obesity, type 2 diabetes, and cardiovascular disease. According to the 2009-2010 National Health and Nutrition Examination Survey (NHANES), an in-person and phone follow-up survey, 50.6% of U.S. adults consumed at least one SSB on a given day. In addition, SSB intake varies by geographical regions: the prevalence of daily SSB intake was higher among U.S. adults living in the Northeast (68.4%) and South (66.7%) than among persons living in the Midwest (58.8%). In 2013, the Behavioral Risk Factor Surveillance System (BRFSS), a telephone survey, revised the SSB two-item optional module to retain the first question on regular soda and expand the second question to include more types of SSBs than just fruit drinks. Using 2013 BRFSS data, self-reported SSB (i.e., regular soda, fruit drinks, sweet tea, and sports or energy drinks) intake among adults (aged ≥18 years) was assessed in 23 states and the District of Columbia (DC). The overall age-adjusted prevalence of SSB intake ≥1 time per day was 30.1% and ranged from 18.0% in Vermont to 47.5% in Mississippi. Overall, at least once daily SSB intake was most prevalent among adults aged 18-24 years (43.3%), men (34.1%), non-Hispanic blacks (blacks) (39.9%), unemployed adults (34.4%), and persons with less than a high school education (42.4%). States can use the data for program evaluation and monitoring trends, and information on disparities in SSB consumption could be used to create targeted intervention efforts to reduce SSB consumption.

Reducing consumption of calories from added sugars is a recommendation of the 2010 Dietary Guidelines for Americans and an objective of Healthy People 2020. Sugar-sweetened beverages (SSB) are major sources of added sugars in the diets of U.S. residents. Daily SSB consumption is associated with obesity and other chronic health conditions, including diabetes and cardiovascular disease. U.S. adults consumed an estimated average of 151 kcal/day of SSB during 2009-2010, with regular (i.e., nondiet) soda and fruit drinks representing the leading sources of SSB energy intake. However, there is limited information on state-specific prevalence of SSB consumption. To assess regular soda and fruit drink consumption among adults in 18 states, CDC analyzed data from the 2012 Behavioral Risk Factor Surveillance System (BRFSS). Among the 18 states surveyed, 26.3% of adults consumed regular soda or fruit drinks or both ≥1 times daily. By state, the prevalence ranged from 20.4% to 41.4%. Overall, consumption of regular soda or fruit drinks was most common among persons aged 18‒34 years (24.5% for regular soda and 16.6% for fruit drinks), men (21.0% and 12.3%), non-Hispanic blacks (20.9% and 21.9%), and Hispanics (22.6% and 18.5%). Persons who want to reduce added sugars in their diets can decrease their consumption of foods high in added sugars such as candy, certain dairy and grain desserts, sweetened cereals, regular soda, fruit drinks, sweetened tea and coffee drinks, and other SSBs. States and health departments can collaborate with worksites and other community venues to increase access to water and other healthful beverages.

Because there is limited information on associations between health-related knowledge and sugar-sweetened beverage (SSB) intake, our cross-sectional study examined this question using the 2010 HealthStyles Survey data for 3,926 adults (aged ≥18 years). Multivariable logistic regression analysis was used to estimate the adjusted odds ratios and 95% CIs for drinking SSBs ≥2 times per day. About 31% of adults consumed SSBs ≥1 time per day, with 20% doing so ≥2 times per day. About eight of 10 adults agreed that drinking SSBs can contribute to weight gain, yet, eight of 10 adults in this study did not know the actual kilocalorie content of a 24-oz fountain soda. After controlling for age, sex, race/ethnicity, education level, annual household income, and geographic region, the odds for drinking SSBs ≥2 times per day were significantly higher among adults who neither agreed nor disagreed (ie, were neutral) that drinking SSBs can contribute to weight gain (odds ratio 1.61, 95% CI 1.15 to 2.25 vs agree); however, knowledge about the energy content of regular soda was not associated with SSB intake. Our finding that knowledge about the adverse effects of SSB intake is significantly associated with SSB intake among adults suggests that health education regarding the potential contribution of excess energy intake from SSBs to weight gain could contribute to lowered consumption and lower rates of obesity. Although knowledge about the kilocalorie content of regular soda was unrelated to SSB intake, health education on the kilocalorie content of SSBs may still be beneficial because most adults did not know the actual kilocalorie content of SSBs. Longitudinal studies are needed to explore associations between knowledge about energy provided by SSBs and SSB intake., (Published by Elsevier Inc.)

Objectives: To compare 7 beverage intake survey questions against criterion data from 24-hour dietary recall interviews (24HrDRIs) among adolescents., Methods: Data were available from 610 US high school students completing a survey and ≥3 24HrDRIs. Analyses compared mean intake (times/day) calculated from the survey to intake (servings/day) from the 24HrDRIs. Proportions of students reporting intake of ≥1 times/day were compared to the 24HrDRI results., Results: Survey data significantly correlated with 24HrDRI data (all corrected r: 0.26-0.49). Survey results differed from 24HrDRI results on reported intake of 5 beverages., Conclusion: Intake from these beverage questions should be reported in times/day, which is related to, but not a proxy for, servings/day. These questions are useful for population-level surveillance of beverage intake and monitoring trends over time.

Introduction: Water is vital for life, and plain water is a calorie-free option for hydration. Increasing consumption of drinking water is a strategy to reduce energy intake and lose or maintain weight; however, information on the characteristics of consumers who drink water is limited. Our objective was to describe the characteristics of people who have a low intake of drinking water and to determine associations between their behaviors and attitudes and their intake of water., Methods: We analyzed data from a nationally representative sample of 3,397 US adults who participated in the National Cancer Institute's 2007 Food Attitudes and Behaviors Survey. Multivariable logistic regression was used to identify sociodemographic characteristics and health-related behaviors and attitudes associated with self-reported drinking water intake of less than 4 cups per day., Results: Overall, 7% of adults reported no daily consumption of drinking water, 36% reported drinking 1 to 3 cups, 35% reported drinking 4 to 7 cups, and 22% reported drinking 8 cups or more. The likelihood of drinking less than 4 cups of water daily was significantly higher among participants aged 55 years or older than among those aged 18 to 34 (adjusted odds ratio [AOR], 1.3), among residents of the Northeast than among residents of the South (AOR, 1.4), among participants who consumed 1 cup or less of fruits or vegetables per day than among those who consumed 4.5 cups or more (AOR, 3.0), among participants who did not exercise than among those who exercised 150 minutes or more per week (AOR, 1.7), and among participants who were neither trying to gain nor lose weight than among those trying to lose weight (AOR, 1.3)., Conclusion: Low drinking water intake was associated with age, region of residence, and several unhealthful behaviors and attitudes. Understanding characteristics associated with low drinking water intake may help to identify populations that could benefit from interventions to help adults drink more water.

Sales of sports and energy drinks have increased dramatically, but there is limited information on regular consumers of sports and energy drinks. Characteristics associated with sports and energy drink intake were examined among a sample representing the civilian noninstitutionalized US adult population. The 2010 National Health Interview Survey data for 25,492 adults (18 years of age or older; 48% males) were used. Nationwide, 31.3% of adults were sports and energy drink consumers during the past 7 days, with 21.5% consuming sports and energy drinks one or more times per week and 11.5% consuming sports and energy drinks three or more times per week. Based on multivariable logistic regression, younger adults, males, non-Hispanic blacks and Hispanics, not-married individuals, adults with higher family income, those who lived in the South or West, adults who engaged in leisure-time physical activity, current smokers, and individuals whose satisfaction with their social activities/relationships was excellent had significantly higher odds for drinking sports and energy drinks one or more times per week. In this model, the factor most strongly associated with weekly sports and energy drink consumption was age (odds ratio [OR]=10.70 for 18- to 24-year-olds, OR=6.40 for 25- to 39-year-olds, OR=3.17 for 40- to 59-year-olds vs 60 years or older). Lower odds for consuming sports and energy drinks one or more times per week were associated with other/multiracial (OR=0.80 vs non-Hispanic white) and obesity (OR=0.87 vs underweight/normal weight). Separate modeling of the association between other beverage intake and sports and energy drink intake showed that higher intake of regular soda, sweetened coffee/tea drinks, fruit drinks, milk, 100% fruit juice, and alcohol were significantly associated with greater odds for drinking sports and energy drinks one or more times per week. These findings can help medical care providers and public health officials identify adults most in need of encouragement to reduce sports and energy drink intake and increase healthier beverage intake., (Published by Elsevier Inc.)

Drinking plain water instead of sugar-sweetened beverages is one approach for reducing energy intake. Only a few studies have examined characteristics associated with plain water intake among US youth. The purpose of our cross-sectional study was to examine associations of demographic characteristics, weight status, dietary habits, and other behavior-related factors with plain water intake among a nationally representative sample of US high school students. The 2010 National Youth Physical Activity and Nutrition Study data for 11,049 students in grades 9 through 12 were used. Multivariable logistic regression analysis was used to calculate adjusted odds ratios (ORs) and 95% CIs for variables associated with low water intake (<3 times/day). Nationwide, 54% of high school students reported drinking water <3 times/day. Variables significantly associated with a greater odds for low water intake were age ≤15 years (OR 1.1), consuming <2 glasses/day of milk (OR 1.5), nondiet soda ≥1 time/day (OR 1.6), other sugar-sweetened beverages ≥1 time/day (OR 1.4), fruits and 100% fruit juice <2 times/day (OR 1.7), vegetables <3 times/day (OR 2.3), eating at fast-food restaurants 1 to 2 days/week and ≥3 days/week (OR 1.3 and OR 1.4, respectively), and being physically active ≥60 minutes/day on <5 days/week (OR 1.6). Being obese was significantly associated with reduced odds for low water intake (OR 0.7). The findings of these significant associations of low water intake with poor diet quality, frequent fast-food restaurant use, and physical inactivity may be used to tailor intervention efforts to increase plain water intake as a substitute for sugar-sweetened beverages and to promote healthy lifestyles., (Published by Elsevier Inc.)

Background: Due to limited information on sugar drink counseling, characteristics of parents who reported ever receiving counseling from a child's doctor to limit a child's sugar drink intake were examined., Methods: This cross-sectional analysis was conducted on a convenient sample of 1570 US parents (aged ≥ 18 years) using the 2009 HealthStyles Survey. The outcome measure was parents with children aged ≤ 18 years who reported being told by a child's doctor to limit a child's sugar drink intake. Data were weighted to provide national estimates. Multivariable logistic regression was used to examine factors associated with ever receiving sugar-drink counseling from a child's doctor., Results: Only 23% of parents reported receiving counseling from a child's doctor to limit a child's sugar drink intake. Parental factors significantly associated with receiving this counseling were: being male (adjusted odds ratio (OR) = 1.38; 95% confidence interval (CI) = 1.02, 1.86), having an annual household income of <$25 000 (versus ≥$60 000, OR = 2.12; 95% CI = 1.33, 3.38) and parents who agreed with 'enjoying learning about health issues' (versus disagree, OR = 2.43; 95% CI = 1.36, 4.36). Age, race/ethnicity, education and marital status were not significantly associated with receiving counseling., Conclusions: Few parents reported ever receiving counseling from a child's doctor, and we found a few differences among those reporting sugar drink counseling.

This cross-sectional study examined associations of demographic characteristics, weight status, availability of school vending machines, and behavioral factors with sugar-sweetened beverage (SSB) intake, both overall and by type of SSB, among a nationally representative sample of high school students. The 2010 National Youth Physical Activity and Nutrition Study data for 11,209 students (grades 9-12) were used. SSB intake was based on intake of 4 nondiet beverages [soda, other (i.e., fruit-flavored drinks, sweetened coffee/tea drinks, or flavored milk), sports drinks, and energy drinks]. Nationwide, 64.9% of high school students drank SSB ≥1 time/d, 35.6% drank SSB ≥2 times/d, and 22.2% drank SSB ≥3 times/d. The most commonly consumed SSB was regular soda. Factors associated with a greater odds for high SSB intake (≥3 times/d) were male gender [OR = 1.66 (95% CI = 1.41,1.95); P < 0.05], being non-Hispanic black [OR = 1.87 (95% CI = 1.52, 2.29); P < 0.05], eating at fast-food restaurants 1-2 d/wk or eating there ≥3 d/wk [OR = 1.25 (95% CI = 1.05, 1.50); P < 0.05 and OR = 2.94 (95% CI = 2.31, 3.75); P < 0.05, respectively] and watching television >2 h/d [OR = 1.70 (95% CI = 1.44, 2.01); P < 0.05]. Non-Hispanic other/multiracial [OR = 0.67 (95% CI = 0.47, 0.95); P < 0.05] and being physically active ≥60 min/d on <5 d/wk were associated with a lower odds for high SSB intake [OR = 0.85 (95% CI = 0.76, 0.95); P < 0.05]. Weight status was not associated with SSB intake. Differences in predictors by type of SSB were small. Our findings of significant associations of high SSB intake with frequent fast-food restaurant use and sedentary behaviors may be used to tailor intervention efforts to reduce SSB intake among high-risk populations.

The article presents the discussion on federal guidelines supporting a dietary pattern with daily fruit and vegetable consumption and limited added sugars. Topics include Government-published dietary intake estimates for young children being outdated at the national level and unavailable at the state level; and availability of fruits and vegetables and healthy beverages in places where young children live, learn, and play.

Objectives: Frequent sugar-sweetened beverage (SSB) intake is associated with weight gain in women, and pre-pregnancy overweight and excessive gestational weight gain are linked to adverse pregnancy outcomes. SSB intake information for women of reproductive age (WRA) is limited. We described SSB intake among non-pregnant and pregnant WRA and identified correlates of daily intake. Methods: Using 2017 Behavioral Risk Factor Surveillance System data, we analyzed SSB intake (regular soda, fruit drinks, sweet tea, sports/energy drinks) for 11,321 non-pregnant and 392 pregnant WRA (18–49 years) in 12 states and D.C. Adjusted odds ratios (aOR) for daily (≥ 1 time/day) SSB intake (reference: < 1 time/day) by characteristics were estimated using multivariable logistic regression. Results: Overall, 27.3% of non-pregnant and 21.9% of pregnant women reported consuming SSBs ≥ 1 time/day; 12.6% and 9.7%, respectively, consumed SSBs ≥ 2 times/day. Among non-pregnant women, odds of daily SSB intake were higher for women who were non-Hispanic black (aOR 2.04, 95% CI 1.55–2.69) vs. non-Hispanic white; had ≤ high school education (aOR 2.79, CI 2.26–3.44) or some college (aOR 1.85, CI 1.50–2.27) vs. college graduates; lived in nonmetropolitan counties (aOR 1.35, CI 1.11–1.63) vs. metropolitan; had no physical activity (aOR 1.72, CI 1.43–2.07) vs. some; were former (aOR 1.51, CI 1.17–1.94) or current (aOR 3.48, CI 2.82–4.28) smokers vs. nonsmokers. Among pregnant women, those not married had higher odds (aOR 2.81, CI 1.05–7.51) for daily SSB intake than married women. Conclusions: One in five pregnant women and one in four non-pregnant women of reproductive age consumed SSBs at least once per day. Sociodemographic and behavioral correlates of daily SSB intake were identified. [ABSTRACT FROM AUTHOR]

The article discusses research which compared beverage intake survey questions to results of 24-hour dietary recall interviews (24HrDRIs) of adolescents. It describes use of the Youth Risk Behavior Surveillance System (YRBSS) by the U.S. Centers for Disease Control and Prevention (CDC) in health risk monitoring among adolescents. Data from the National Youth Physical Activity and Nutrition Study were reportedly used in this study. Results of statistical analysis performed are reported.

The article reports on the extent of beverage consumption among high school students in the U.S. in 2010, based on data from the 2010 National Youth Physical Activity and Nutrition Study analyzed by the U.S. Centers for Disease Control and Prevention (CDC). According to results, 24.3 percent of students drank a serving of regular soda or pop, while 16.1 percent drank a serving of sports drink, and 16.9 percent drank a serving of another sugar-sweetened beverage (SSB) one or more times per day during the same period. A higher number of male students appeared to drink SSBs compared to females, and African American students were more likely to consume SSBs than white and Hispanic students. INSET: What is already known on this topic?.

Purpose: This study examined associations between knowledge of sugar-sweetened beverage (SSB)-related health conditions and SSB intake among US adults.Design: Quantitative, cross-sectional study.Subject: The 2014 SummerStyles survey data for 4163 US adults (≥18 years) were used.Measures: The outcome measure was frequency of SSB intake (regular soda, fruit drinks, sports or energy drinks, sweetened coffee/tea drinks). Exposure measures were knowledge of 6 SSB-related health conditions: weight gain, diabetes, cavities, high cholesterol, heart disease, and hypertension.Analysis: Six logistic regression models were used to estimate adjusted odds ratios (ORs) for consuming SSBs ≥2 times/d according to knowledge of SSB-related health conditions.Results: Overall, 37.8% of adults reported consuming SSBs ≥2 times/d. Although most adults identified that weight gain (80.2%), diabetes (73.6%), and cavities (71.8%) are related to drinking SSBs, fewer adults identified high cholesterol (24.1%), heart disease (31.5%), and hypertension (33.0%) as being related to drinking SSBs. Crude analyses indicated that lower SSB intake was significantly associated with knowledge of the associations between SSBs and weight gain, diabetes, cavities, and heart disease. However, after adjustment for covariates, only lack of knowledge of the association between heart disease and SSBs was significantly associated with consuming SSBs ≥2 times/d (OR = 1.29) than non-SSB consumers.Conclusions: The finding that knowledge of SSB-related health conditions, in general, was not associated with high SSB intake suggests that knowledge on SSB-related health conditions alone may not be sufficient for adult behavior change.

Objectives: Sugar-sweetened beverage (SSB) intake among U.S. adults is associated with obesity and type 2 diabetes. An association between SSB intake and asthma has been shown among U.S. children and Australian adults, but scant published information exists for U.S. adults. We examined associations between SSB intake and current asthma among U.S. adults, and the role of obesity in this association.Methods: We analyzed 2013 Behavioral Risk Factor Surveillance System data for 146,990 adults (≥18years) from 23 states and the District of Columbia. We used multivariable logistic regression to estimate associations between current asthma and frequency (none, <1 time/day, once/day, ≥2 times/day) of SSB intake (soda, fruit drink, sweet tea, and sports/energy drink). SSB intake was measured using two questions. Covariates included age, sex, race/ethnicity, education, and smoking. Obesity, based on self-reported height and weight, was assessed as an effect modifier.Results: Overall, 9.1% of adults reported current asthma: 8.5% of adults who did not consume SSBs had current asthma vs 12.1% of adults who consumed SSBs ≥2 times/day. There was no difference in asthma prevalence with SSB intake <1 time/day (8.7%) or once/day (8.7%). Among non-obese adults, the odds of having current asthma were higher among those who consumed SSBs ≥2 times/day (aOR=1.66, 95%CI=1.39, 1.99) than non-SSB consumers. However, SSB intake frequency was not associated with asthma among obese adults.Conclusions: Frequent SSB consumption was associated with asthma among non-obese adults. Research on asthma prevention should further consider the potential adverse effects of high SSB intake among U.S. adults. [ABSTRACT FROM AUTHOR]
