Trends in the contribution of greenhouse gas emissions from food and beverage purchases in Mexico: 1989-2020.

BACKGROUND: Assessing the trends in dietary GHGE considering the social patterning is critical for understanding the role that food systems have played and will play in global emissions in countries of the global south. Our aim is to describe dietary greenhouse gas emissions (GHGE) trends (overall and by food group) using data from household food purchase surveys from 1989 to 2020 in Mexico, overall and by education levels and urbanicity. METHODS: We used cross-sectional data from 16 rounds of Mexico's National Income and Expenditure Survey, a nationally representative survey. The sample size ranged from 11,051 in 1989 to 88,398 in 2020. We estimated the mean total GHGE per adult-equivalent per day (kg CO2-eq/ad-eq/d) for every survey year. Then, we estimated the relative GHGE contribution by food group for each household. These same analyses were conducted stratifying by education and urbanicity. RESULTS: The mean total GHGE increased from 3.70 (95%CI: 3.57, 3.82) to 4.90 (95% CI 4.62, 5.18) kg CO2-eq/ad-eq/d between 1989 and 2014 and stayed stable between 4.63 (95% CI: 4.53, 4.72) and 4.89 (95% CI: 4.81, 4.96) kg CO2-eq/ad-eq/d from 2016 onwards. In 1989, beef (19.89%, 95% CI: 19.18, 20.59), dairy (16.87%, 95% CI: 16.30, 17.42)), corn (9.61%, 95% CI: 9.00, 10.22), legumes (7.03%, 95% CI: 6.59, 7.46), and beverages (6.99%, 95% CI: 6.66, 7.32) had the highest relative contribution to food GHGE; by 2020, beef was the top contributor (17.68%, 95%CI: 17.46, 17.89) followed by fast food (14.17%, 95% CI: 13.90, 14.43), dairy (11.21%, 95%CI: 11.06, 11.36), beverages (10.09%, 95%CI: 9.94, 10.23), and chicken (10.04%, 95%CI: 9.90, 10.17). Households with higher education levels and those in more urbanized areas contributed more to dietary GHGE across the full period. However, households with lower education levels and those in rural areas had the highest increase in these emissions from 1989 to 2020. CONCLUSIONS: Our results provide insights into the food groups in which the 2023 Mexican Dietary Guidelines may require to focus on improving human and planetary health.

Coffee, Tea, and Mammographic Breast Density in Premenopausal Women.

Studies have investigated the associations of coffee and tea with mammographic breast density (MBD) in premenopausal women with inconsistent results. We analyzed data from 375 premenopausal women who attended a screening mammogram at Washington University School of Medicine, St. Louis, MO in 2016, and stratified the analyses by race (non-Hispanic White (NHW) vs. Black/African American). Participants self-reported the number of servings of coffee, caffeinated tea, and decaffeinated tea they consumed. Volpara software was used to determine volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV). We used generalized linear regression models to quantify the associations of coffee and tea intake with MBD measures. Coffee: ≥1 time/day (ß = 1.06; 95% CI = 0.93-1.21; p-trend = 0.61) and caffeinated tea: ≥1 time/day (ß = 1.01; 95% CI = 0.88-1.17; p-trend = 0.61) were not associated with VPD. Decaffeinated tea (≥1 time/week) was positively associated with VPD in NHW women (ß = 1.22; 95% CI = 1.06-1.39) but not in African American women (ß = 0.93; 95% CI = 0.73-1.17; p-interaction = 0.02). Coffee (≥1 time/day) was positively associated with DV in African American women (ß = 1.52; 95% CI = 1.11-2.07) but not in NHW women (ß = 1.10; 95% CI = 0.95-1.29; p-interaction = 0.02). Our findings do not support associations of coffee and caffeinated tea intake with VPD in premenopausal women. Positive associations of decaffeinated tea with VPD, with suggestions of effect modification by race, require confirmation in larger studies with diverse study populations.

Association of coffee, green tea, and caffeine with the risk of dementia in older Japanese people.

OBJECTIVES: Coffee, green tea, and caffeine are potential preventive factors for dementia, but the underlying evidence is insufficient. This study aimed to examine associations between the consumption of coffee, green tea, and caffeine and dementia risk in middle-aged and older people. METHODS: This was a cohort study with an 8.0-year follow-up. Participants were community-dwelling individuals (n = 13,757) aged 40-74 years. A self-administered questionnaire survey was conducted in 2011-2013. Predictors were the consumption of coffee/green tea, from which caffeine consumption was estimated. The outcome was incident dementia obtained from the long-term care insurance database. Covariates were demographic factors, body mass index, physical activity, energy, smoking, drinking, and disease history. Adjusted hazard ratios (HRs) were calculated using Cox proportional hazards models. HRs were also calculated using a Cox model with delayed entry. RESULTS: The number of dementia cases during the study period was 309. Participants with higher coffee consumption had lower HRs (adjusted p for trend = 0.0014), with the fifth quintile (≥326 ml/day) having a significantly lower HR (0.49, 95% confidence interval [CI]: 0.30-0.79) than the first quintile (<26 ml/day, reference). Similarly, participants with higher caffeine consumption had a significantly lower HR (adjusted p for trend = 0.0004) than the reference. The Cox model with delayed entry yielded similar results. These associations were significant in men, but not in women. Moreover, participants who consumed 2-2.9 cups/day and ≥3 cups/day of coffee had lower HRs (0.69, 95% CI: 0.48-0.98 and 0.53, 95% CI: 0.31-0.89, respectively) than those who consumed 0 cup/day. The association between green tea consumption and reduced dementia risk was significant (adjusted p for trend = 0.0146) only in the 60-69 years age subgroup. CONCLUSIONS: High levels of coffee and caffeine consumption were significantly associated with a reduced dementia risk in a dose-dependent manner, especially in men. Moreover, coffee consumption of ≥3 cups/day was associated with a 50% reduction in dementia risk.

Determinants of the Consumption of Regular Soda, Sport, and Energy Beverages in Spanish Adolescents.

Increasing sugar-sweetened beverages (SSB) consumption and associated health impacts warrant health-policy action. We assessed associations of socioeconomic and lifestyle variables with adolescents' consumption of regular soda (RSD), sport (SD), and energy (ED) drinks. Cross-sectional study of 3930 Spanish adolescents (2089 girls, 1841 boys) aged 13-18 years). We compared frequency of consuming each SSB type (European Food Safety Authority questionnaire) with sociodemographic and lifestyle variables (standardized questions). RSD, SD, and ED were consumed at least weekly by 72.7%, 32.3%, and 12.3% of participants, respectively, and more frequently (p < 0.001) by boys, compared to girls. Multivariate ordinal logistic regression showed inverse association between RSD, SD, and ED consumption and parental occupation-based socioeconomic status (p < 0.01). Daily smoking was associated (p < 0.001) with higher ED (OR 3.64, 95% CI 2.39-5.55) and RSD (OR 2.15, 95% CI 1.56-2.97) consumptions. SD intake was associated inversely with smoking (OR 0.60, 95% CI 0.40-0.89, p = 0.012) and directly with physical activity (OR 2.93, 95% CI 2.18-3.95, p < 0.001). School performance was lower among ED (OR 2.14, 95% CI, 1.37-3.35, p = 0.001) and RSD (OR 1.81, 95% CI 1.24-2.64, p = 0.002) consumers, compared to SD. Maleness and low socioeconomic status predicted SSB consumption. Smoking and low school performance were associated with higher ED and RSD intakes.

Food Insecurity and Dietary Intake among College Students with Unlimited Meal Plans at a Large, Midwestern University.

BACKGROUND: Food insecurity, a state of not being able to consistently access nutritious food due to financial constraints, has been associated with poor dietary intake among college students. The extent to which campus food resources contribute to this association is unknown. OBJECTIVES: This study examined the association between food insecurity and dietary intake in a sample of undergraduate students with unlimited meal plans and dining hall access at a large, public Midwestern university. DESIGN: The study design is cross-sectional. The data used are baseline data from a broader sugar-sweetened beverage intervention study that were collected using a Qualtrics survey prior to the intervention. PARTICIPANTS/SETTING: The sample consisted of 1033 undergraduate students recruited from 3 dining halls. The data were collected in November 2018. MAIN OUTCOME MEASURES: Food security was assessed using the 6-item Short Form Food Security Survey Module. Dietary intake was assessed using the National Cancer Institute 26-item Dietary Screener Questionnaire and the Beverage Intake Questionnaire-15. STATISTICAL ANALYSES PERFORMED: Generalized linear regression models were used to examine differences in dietary intake by students' food security status, adjusting for students' sociodemographic characteristics. RESULTS: In the sample, 14% of students were food-insecure. After adjusting for sociodemographic variables, food-insecure students reported 9% lower intake of fruits (P = 0.02), 9% lower intake of vegetables (P < 0.001), 10% higher intake of dairy (P = 0.002), 6% higher intake of total added sugars (P = 0.01), 10% higher intake of added sugars from sugar-sweetened beverages (P = 0.01), 4% higher intake of calcium (P = 0.01), and 4% lower intake of fiber (P = 0.01) compared with food-secure students. With respect to beverage intake, food-insecure students had 56% higher intake of total sugar-sweetened beverages (P = 0.002), which was driven by 185% higher intake of energy and sports drinks (P = 0.001), and 121% higher intake of sweetened teas (P = 0.001). CONCLUSIONS: Despite having identical food resources within campus dining halls, there were significant differences in the diets of college students by food security status.

Coffee Consumption and the Risk of All-Cause and Cause-Specific Mortality in the Korean Population.

BACKGROUND: There is a dearth of information regarding the association between coffee consumption and its health effects with respect to mortality among Korean people. OBJECTIVE: The aim of this study was to examine the association between coffee consumption and all-cause mortality and cause-specific mortality risks in the Korean population. DESIGN: This prospective cohort study had a median follow-up period of 9.1 years. PARTICIPANTS/SETTING: In total, 173,209 participants aged 40 years and older from the Health Examinees study were enrolled between 2004 and 2013. The analytic sample included 110,920 participants without diabetes, cardiovascular disease (CVD), or cancer at baseline who could be linked with their death information. MAIN OUTCOME MEASURES: Deaths of participants until December 31, 2018 were ascertained using the death certificate database of the National Statistical Office. Cause of death was classified according to the International Classification of Diseases, 10th Revision. STATISTICAL ANALYSES PERFORMED: Participants were categorized according to the amount and type of coffee consumed. Cox proportional hazards regression analysis was performed to estimate the hazard ratio (HR) and 95%CI of all-cause mortality and cause-specific mortality, such as CVD and cancer mortality. RESULTS: Compared with nonconsumers of coffee, participants who consumed > 3 cups/day had a reduced risk of all-cause mortality (HR 0.79, 95% CI 0.66 to 0.95). Participants who consumed ≤1 cup/day and 1 to 3 cups/day had a reduced risk of CVD mortality (≤1 cup/day: HR 0.58, 95% CI 0.69 to 0.94; 1 to 3 cups/day: HR 0.62, 95% CI 0.41 to 0.96). CONCLUSIONS: This study provides evidence that greater coffee consumption is associated with a decreased risk of all-cause mortality and moderate coffee consumption (approximately 3 cups/day) is associated with a decreased risk of CVD mortality, regardless of the type of coffee, in a Korean population.

Post-diagnostic coffee and tea consumption and breast cancer survival.

BACKGROUND: We examined the role of post-diagnostic coffee and tea consumption in relation to breast cancer-specific and all-cause mortality among women with breast cancer in prospective cohort studies. METHODS: We identified 8900 women with stage I-III breast cancer from 1980 through 2010 in the Nurses' Health Study (NHS) and from 1991 through 2011 in the NHSII. Post-diagnostic coffee and tea consumption was assessed by a validated food frequency questionnaire every 4 years after diagnosis. RESULTS: During up to 30 years of follow-up, we documented 1054 breast cancer-specific deaths and 2501 total deaths. Higher post-diagnostic coffee consumption was associated with a lower breast cancer-specific mortality: compared with non-drinkers, >3 cups/day of coffee was associated with a 25% lower risk (hazard ratio (HR) = 0.75, 95% confidence interval (CI) = 0.59-0.96; Ptrend = 0.002). We also observed a lower all-cause mortality with coffee consumption: compared with non-drinkers, >2 to 3 cups/day was associated with a 24% lower risk (HR = 0.76, 95% CI = 0.66-0.87) and >3 cups/day was associated with a 26% lower risk (HR = 0.74, 95% CI = 0.63-0.87, Ptrend < 0.0001). Post-diagnostic tea consumption was associated with a lower all-cause mortality: compared with non-drinkers, >3 cups/day was associated with a 26% lower risk (HR = 0.74, 95% CI = 0.58-0.95; Ptrend = 0.04). CONCLUSIONS: Among breast cancer survivors, higher post-diagnostic coffee consumption was associated with better breast cancer and overall survival. Higher post-diagnostic tea consumption may be related to better overall survival.

Added, free and total sugar content and consumption of foods and beverages in Canada.

BACKGROUND: Consumption of sugars contributes to obesity and various chronic diseases. The U.S. Department of Agriculture and the World Health Organization recommend that added and free sugar consumption be less than 10% of total energy intake (TEI). However, in Canada, the added and free sugar content of foods and beverages is not documented, so Canadians' consumption and compliance with the above recommendations are unknown. DATA AND METHODS: This study calculated the added and free sugar content of all 5,374 foods and beverages recorded in the 24-hour dietary recalls of the 2015 Canadian Community Health Survey - Nutrition using established procedures. The usual intake of added, free and total sugars was estimated with the National Cancer Institute method. RESULTS: In 2015, residents of Canada consumed an average of 57.1 g/day of added sugars, 67.1 g/day of free sugars and 105.6 g/day of total sugars. This represented 11.1%, 13.3% and 21.6% of TEI for added, free and total sugar intake, respectively. Among all Canadians, 49.0% consumed less than 10% of TEI from added sugars, while 33.8% consumed less than 10% of TEI from free sugars. The food groups with the highest added and free sugar content were desserts and sweets, breakfast cereals, baked products, beverages, and snacks. Desserts and sweets and beverages were the two main contributors of sugar in the Canadian diet. DISCUSSION: The majority of Canadians consumed more added and free sugars than recommended. Estimating added and free sugar content and consumption could help researchers assess the health of Canadians and the economic burden of excessive sugar consumption and could help policy makers articulate intervention targets.

Relations between sweetened beverage consumption and individual, interpersonal, and environmental factors: a 6-year longitudinal study in German children and adolescents.

OBJECTIVES: This study aims to characterize the consumption of sweetened beverages (SB) among young people in Germany in terms of individual and interpersonal-environmental correlates. METHODS: A representative sample of children and adolescents from Germany was assessed twice, 6 years apart (total longitudinal sample n = 11,691 children and adolescents aged between 0 and 17 years old; weighted). The relations between individual and interpersonal-environmental factors at baseline with SB intake 6 years later were analysed using bivariate and multivariate methods. RESULTS: The majority of children and adolescents in Germany consume sweetened beverages weekly, 23% daily. SB consumption is particularly high in boys and often accompanied by other unhealthy lifestyle behaviours including a high level of tobacco and media consumption with a concurrent deficiency in fruit and vegetable consumption. Interpersonal factors associated with higher sweetened beverage consumption include low socio-economic status, tobacco consumption of parents, and older maternal age. CONCLUSIONS: Research on factors that correlate with sweetened beverage consumption is crucial to design effective interventions. Our findings underline the importance of complex, multi-level interventions to target sweetened beverage intake and obesity.

Dietary factors and risk of mortality among patients with esophageal cancer: a systematic review.

BACKGROUND: The effects of dietary factors on prognosis of esophageal cancer remain unclear. This systematic review and meta-analysis aimed to assess the association between dietary intake and the risk of mortality among patients with esophageal cancer. METHODS: Six electronic databases (PubMed, Web of Science, OVID, ProQuest, CNKI and Wanfang) were searched for studies published up to Oct. 2019 that examined the association between dietary intake and all-cause mortality, esophageal cancer-specific mortality and esophageal cancer recurrence. The pooled hazard ratio (HR) with 95% confidence interval (CI) were derived by comparing the highest with the lowest categories of each dietary item and by using random effect models. RESULTS: A total of 15 cohort studies were included in this study and all reported pre-diagnosis dietary exposure; two focused on dietary folate, 12 on alcohol consumption and three on other dietary components (sugary beverages, phytochemicals and preserved vegetables). When comparing the highest with the lowest categories, dietary folate intake was associated with a reduced risk of esophageal cancer-specific mortality in patients with esophageal squamous cell carcinoma (HR: 0.41, 95% CI: 0.25-0.69), with low heterogeneity (I2 = 0%, P = 0.788). When comparing the highest with the lowest categories of alcohol consumption, alcohol consumption was associated with an increased risk of all-cause mortality in patients with esophageal squamous cell carcinoma (HR: 1.29, 95% CI: 1.07-1.55; heterogeneity: I2 = 53%, P = 0.030), but this increased risk was not significant in patients with esophageal adenocarcinoma (HR = 1.05, 95% CI: 0.84-1.32). CONCLUSIONS: This review with pre-diagnostic dietary exposure showed that dietary folate intake was associated with a reduced risk of mortality of esophageal squamous cell carcinoma, whereas alcohol consumption was associated with an increased risk. More studies are needed to investigate effect of dietary factors, especially post-diagnosis dietary consumption, on esophageal cancer prognosis.

Motivations Influencing Caffeine Consumption Behaviors among College Students in Korea: Associations with Sleep Quality.

Caffeinated beverages are a part of daily life. Caffeinated beverages such as coffee, tea, energy drinks, and soft drinks are easy to purchase and are frequently consumed by young college students. Moreover, smoking influences the consumption of caffeinated beverages. The concentration of caffeine in these products is an attractive factor for individuals that desire the effects of caffeine; however, abusing such products may lead to poor sleep quality. The motivations that drive caffeinated beverage consumption were investigated in this study through a survey. Self-reported questionnaires were distributed on campus to students enrolled at a university in Korea. The motivations of the students for consuming each caffeinated beverage and their sleep quality were investigated. The results of exploratory factor analysis showed the motivations for caffeinated beverage consumption were alertness, taste, mood, socialization, health benefits, and habit. The motivations for consuming each caffeinated beverage product were different. For instance, coffee consumption was motivated by a desire for alertness (B = .107, SE = .049, t = 2.181, p < 0.05) and by habit (B = .345, SE = .046, t = 7.428, p < 0.001), whereas tea consumption was influenced by socialization (B = .142, SE = .060, t = 2.357, p < 0.05). Energy drink consumption was motivated by a desire for alertness (B = .100, SE = .034, t = 2.966, p < 0.01) and health benefits (B = .120, SE = .051, t = 2.345, p < 0.05), while the consumption of soft drinks was not motivated by any specific factors. Caffeinated beverage consumption did not show a significant relationship with sleep quality, although the general sleep quality of the respondents was poor. Smoking status showed significant differences in coffee and tea consumption as well as sleep quality. Smokers had a higher intake of coffee and a lower intake of tea than non-smokers. No interaction effect between smoking and coffee on sleep quality was found. Labeling detailing the amount of caffeine in products is necessary and a cautionary statement informing consumers that smoking cigarettes enhances the effects of caffeine should be included.

Fluid intake and clinicopathological characteristics of bladder cancer: the West Midlands Bladder Cancer Prognosis Programme.

OBJECTIVE: Between 10 and 20% of bladder cancer patients who are diagnosed with nonmuscle-invasive bladder cancer will progress to muscle-invasive disease. Risk of progression depends on several factors at diagnosis including age, tumour stage, grade, size and number, and the presence or absence of carcinoma in situ. Fluid intake may be related to these factors. METHODS: Data of 1123 participants from the West Midlands Bladder Cancer Prognosis Programme were used. Data collection was via a semistructured questionnaire, and case report forms were used to collect clinicopathological data. Fluid intake was measured for six main categories: alcoholic fluids, hot fluids, fruit fluids, milk, fizzy drinks, and water, and converted into quintile variables. Multilevel mixed-effects linear regression was performed for every beverage category per clinicopathological variable and corrected for age, gender, and smoking status. RESULTS: Age at diagnosis was distributed differently amongst those in different total fluid intake quintiles (predicted means 71.5, 70.9, 71.5, 69.9, and 67.4, respectively) and showed a significant inverse linear trend in alcohol (P < 0.01), hot fluids (P < 0.01), and total fluids intake (P < 0.01), in nonmuscle-invasive bladder cancer patients. CONCLUSION: Our results suggest an inverse association for alcohol intake and total fluid intake with age at diagnosis. These results should be confirmed by future studies, alongside a possible (biological) mechanism that could influence tumour growth, and the effect of micturition frequency.

Sugar-sweetened beverage consumption among Indigenous Australian children aged 0-3 years and association with sociodemographic, life circumstances and health factors.

OBJECTIVE: To explore beverage intake and associations between sugar-sweetened beverage (SSB) intake and sociodemographic, life circumstances, health and well-being factors in a national cohort of Indigenous children. DESIGN: We calculated prevalence ratios for any SSB consumption across exposures, using multilevel Poisson regression (robust variance), adjusted for age group and remoteness. A key informant focus group contextualised these exploratory findings. SETTING: Diverse settings across Australia. PARTICIPANTS: Families of Indigenous children aged 0-3 years, in the Longitudinal Study of Indigenous Children. RESULTS: Half (50·7 %, n 473/933) of children had ever consumed SSB at survey, increasing from 29·3 % of 0-12-month-olds to 65·7 % of 18-36-month-olds. SSB consumption prevalence was significantly lower in urban and regional v. remote areas, and in families experiencing socio-economic advantage (area-level advantage, caregiver employed, financial security), better life circumstances (caregiver social support, limited exposure to stressors) and caregiver well-being (non-smoking, social and emotional well-being, physical health). SSB consumption prevalence was significantly lower among those engaged with health services (adequate health-service access, regular prenatal check-ups), except SSB consumption prevalence was higher among those who received home visits from an Aboriginal Health Worker compared with no home visits. Key informants highlighted the role of water quality/safety on SSB consumption. CONCLUSIONS: A substantial proportion of Indigenous children in this sample consumed SSB from an early age. Health provider information needs to be relevant to the context of families' lives. Health system strategies must be paired with upstream strategies, such as holistic support programmes for families, reducing racism and improving water quality.

Fluid and total water intake in a senior mediterranean population at high cardiovascular risk: demographic and lifestyle determinants in the PREDIMED-Plus study.

PURPOSE: We aimed to evaluate associations between compliance with recommendations for total water intake (TWI) and total water intake from fluids (TWIF), and some socio-demographic and lifestyle factors of a senior Mediterranean population at high cardiovascular risk. METHODS: Cross-sectional analysis with data of 1902 participants from the PREDIMED-Plus study. A validated 32-item Spanish fluid-intake questionnaire was used to assess beverage consumption and water intake. Multivariable logistic regression models were used to assess the odds ratio (OR) and the 95% confidence interval (CI) for complying with European Food Safety Agency recommendations for TWI and TWIF according to various socio-demographic and lifestyle factors, and for the joint associations of Mediterranean diet (MedDiet) adherence and moderate-vigorous physical activity (MVPA). RESULTS: The mean total volume of fluid intake in the population studied was 1934 ± 617 mL/day. Water was the most frequently consumed beverage. Significant differences between sex were only observed in alcoholic and hot beverage consumption. Compliance with TWIF was associated with being women (OR 3.02; 2.40, 3.80), high adherence to MedDiet (OR 1.07; 1.02, 1.12), and participants who were more engaged in physical activity (PA) (OR 1.07; 1.02, 1.13). Age was inversely associated (OR 0.96; 0.94, 0.98). Similar results for TWI recommendations compliance were observed in relation to being women (OR 5.34; 3.85, 7.42), adherence to MedDiet (OR 1.16; 1.02, 1.31) and PA (OR 1.07; 1.00, 1.15). The joint association of PA and MedDiet, showed that participants with higher adherence to MedDiet and meeting WHO recommendations for MVPA complied better with the TWI recommendations (OR 1.66; 1.19, 2.32). CONCLUSIONS: High compliance with recommendations for TWI was associated with being a woman, and a healthy lifestyle characterized by high adherence to the MedDiet and PA.

Main sources of added sugar in Argentina

The high consumption of added sugars in the diet of the Argentine population and its consequent effect on health are current concerns both at the clinical and public health levels. The objective of this study was to determine the main sources of added sugars in the Argentine diet and the proportional energy contribution of each of them. The sample consisted of 1266 individuals, representative of the country's urban population from 15 to 65 years old, stratified by region, age, gender and socio-economic level. Two 24-hour dietary recalls and one socio-economic questionnaire were carried out. Among the total food and beverages consumed by Argentines, 26.9% of added sugars were provided by soft drinks and 23.8% by infusions. The third place, with 15.4%, came from baked goods (bread, cookies, etc.) and the fourth, with 12%, from ready-to-prepare juices, ahead of sweets and candies and dairy products. Men, compared to women, consumed significantly more added sugars in soft drinks (32.6 vs. 22.1%), while women consumed more added sugars in infusions (25.5 vs. 21.8%), baked goods, sugar and honey. The lower income population consumed significantly more sugar in infusions at the expense of "mate" (21.4 vs. 7 g/day), while no differences were observed in the consumption of soft drinks by socio-economic level (32.9 vs. 34.4 g/day). Urgent measures based on education could improve the consumption habits of added sugars and the health of the population.

El alto consumo de azúcares añadidos en la dieta de la población argentina y su consecuente efecto sobre la salud son preocupaciones actuales tanto a nivel clínico como de salud pública. El objetivo del presente estudio consistió en determinar las principales fuentes de azúcares añadidos de la dieta argentina y determinar el aporte proporcional de energía de cada una de ellas. La muestra consistió en 1266 individuos, representativa de la población urbana del país de 15 a 65 años y estratificada por región, edad, género y nivel socioeconómico. Se efectuaron dos recordatorios de ingesta de 24 horas y un cuestionario de nivel socioeconómico. Entre el total de alimentos y bebidas consumidos por los argentinos el 26.9% del azúcar lo aportaron las gaseosas y el 23.8% las infusiones. El tercer lugar, con 15.4%, provino de los panificados (pan, galletitas, facturas) y el cuarto, con 12%, de jugos listos para preparar, por delante de los dulces y golosinas y lácteos. Los hombres, en comparación con las mujeres consumieron significativamente más azúcares añadidos en gaseosas (32.6 vs. 22.1%) y las mujeres más en infusiones (25.5 vs. 21.8%), panificados, azúcar y miel. La población de menores recursos consumió significativamente más azúcar en infusiones a expensas del mate (21.4 vs. 7 g/día) y no se observaron diferencias en el consumo de gaseosas por nivel socioeconómico (32.9 vs. 34.4 g/día). Urgentes medidas basadas en la educación podrían mejorar los hábitos de consumo de azúcares y la salud de la población.

Principales fuentes de azúcares de adición en Argentina / Main sources of added sugars in Argentina

Urgentes medidas basadas en la educación podrían mejorar los hábitos de consumo de azúcares y la salud de la población.

The high consumption of added sugars in the diet of the Argentine population and its consequent effect on health are current concerns both at the clinical and public health levels. The objective of this study was to determine the main sources of added sugars in the Argentine diet and to determine the proportional energy contribution of each of them. The sample consisted of 1266 individuals, representative of the country's urban population from 15 to 65 years old, stratified by region, age, gender and socio-economic level. Two 24-hour intake records and one socio-economic questionnaire were carried out. Among the total food and beverages consumed, 26.9% of added sugars was contributed by soft drinks and 23.8% by infusions. The third place, with 15.4%, was obtained by baked goods (bread, cookies, etc.) and the fourth, with 12%, from ready-to-prepare juices, ahead of sweets, candies and dairy products. Men, compared to women, consumed significantly more added sugars in soft drinks (32.6 vs. 22.1%) and women more in infusions (25.5% vs. 21.8%), baked goods, sugar and honey. The lower income population consumed significantly more sugar in infusions at the expense of "mate" (21.4 vs. 7 g/day) and no differences were observed in the consumption of soft drinks by socio-economic level (32.9 vs. 34.4 g/day). Urgent measures based on education could improve the consumption habits of added sugars and the health of the population.

Consumo de bebidas açucaradas e fatores associados em adultos / Consumption of sweetened beverages and associated factors in adults

Resumo O objetivo deste estudo foi avaliar o consumo regular de bebidas açucaradas e sua associação com aspectos sociodemográficos e comportamentais de adultos de uma cidade do sudoeste brasileiro. Trata-se de um estudo de base populacional com 1226 adultos de 20 a 59 anos, residentes na zona urbana do município de Viçosa-MG. Foi aplicado um questionário estruturado para medir as condições sociodemográficas e comportamentais. O consumo de bebidas açucaradas foi classificado como regular quando a frequência de ingestão foi igual ou superior a cinco vezes por semana. O consumo regular de bebidas açucaradas foi superior em homens e mulheres com idade entre 20 e 29 anos (p < 0,01). Homens com hábito de realizar refeições em frente à televisão (p = 0,03) e mulheres insatisfeitas com seu peso (p = 0,03) apresentaram maior consumo regular de bebidas açucaradas. Conclui-se que os indivíduos de maior idade apresentaram menor consumo regular de bebidas açucaradas e este consumo esteve associado a comportamentos obesogênicos, como o hábito em realizar refeições em frente à televisão, e em indivíduos insatisfeitos com o peso corporal.

Abstract The aim of this study was to evaluate the regular consumption of sweetened beverages and its association with sociodemographic and behavioral aspects in a city in the southwest of Brazil. It involves is a population-based study of 1,226 adults aged 20 to 59 living in the urban area of the municipality of Viçosa in the state of Minas Gerais. A structured questionnaire to measure sociodemographic and behavioral conditions was applied. The consumption of sweetened beverages was considered regular when the frequency of consumption was five or more times a week. Regular consumption of sweetened beverages was higher in men and women aged between 20 and 29 years (p < 0.01). Men with the habit of eating meals in front of the television (p = 0.03) and women dissatisfied with their weight (p = 0.03) consumed greater regular amounts of sweetened beverages. The conclusion reached is that older individuals showed less regular consumption of sweetened beverages and that the consumption of same was associated with obesogenic behaviors, such as the habit of eating meals in front of the television and among individuals dissatisfied with their body weight.

Intake of caffeine from all sources and reasons for use by college students.

BACKGROUND & AIMS: Caffeine intake in a convenience sample of U.S. college students (N = 1248) was surveyed at five geographically-dispersed United States (U.S.) universities. METHODS: Intake from coffee, tea, soft drinks, energy drinks, gums, and medications was assessed. Associations between caffeine intake and demographic variables including sex, age, race/ethnicity, family income, general health, exercise, weight variables and tobacco use were examined. Reasons for use of caffeine-containing products were assessed. RESULTS: Caffeine, in any form, was consumed by 92% of students in the past year. Mean daily caffeine consumption for all students, including non-consumers, was 159 mg/d with a mean intake of 173 mg/d among caffeine users. Coffee was the main source of caffeine intake in male (120 mg/d) and female (111 mg/d) consumers. Male and female students consumed 53 vs. 30 mg/d of caffeine in energy drinks, respectively, and 28% consumed energy drinks with alcohol on at least one occasion. Students provided multiple reasons for caffeine use including: to feel awake (79%); enjoy the taste (68%); the social aspects of consumption (39%); improve concentration (31%); increase physical energy (27%); improve mood (18%); and alleviate stress (9%). CONCLUSIONS: As in the general U.S. population, coffee is the primary source of caffeine intake among the college students surveyed. Energy drinks provide less than half of total daily caffeine intake but more than among the general population. Students, especially women, consume somewhat more caffeine than the general population of individuals aged 19-30 y but less than individuals aged 31-50 y.

Persistent disparities over time in the distribution of sugar-sweetened beverage intake among children in the United States.

Background: Recent research suggests that sugar-sweetened beverage (SSB) consumption has been declining among US children aged 2-18 y. However, most studies focused on changes in mean intake, ignore high SSB consumers and do not examine intake among vulnerable groups and, including adolescents, low-income households, and several racial/ethnic minorities. Objective: The aim was to estimate usual SSB intake from NHANES surveys from 2003-2004 to 2013-2014 to examine shifts at both the median and 90th percentile among US children, evaluating the extent to which intake disparities in total SSBs and subtypes have persisted. Design: Children 2-18 y from NHANES 2003, 2005, 2007, 2009, 2011 and 2013. SSBs were all non-diet beverages sweetened with sugars including revising all beverages to as consumed status and excluding soy and dairy based beverages. The NCI usual intake method was used to estimate usual intake from two 24-hour recalls. A 2-part correlated model accounted for nonconsumers. Quantile regression was then used to examine differences in SSB usual intakes at the 50th and 90th percentiles by race-ethnicity, and examine interactions indicating whether racial-ethnic disparities in intake were modified by income. Results: Despite considerable declines, children's SSB intake remains high, particularly among heavy consumers. Among adolescents, median SSB intake in 2013-2014 was on the order of 150-200 kcal/d, and heavy intake at the 90th percentile was on the order of 250-300 kcal/d. There were important disparities in intake that persisted over time. Although high household income was associated with lower SSB intake in non-Hispanic white (NHW) children, intakes of non-Hispanic black (NHB) and Mexican-American (MA) children from these households were similar to or higher than those from poor households. There were also large racial/ethnic differences in the types of SSBs consumed. The consumption of regular sodas by NHB children was somewhat lower than among MA and NHW children, whereas fruit drink intake was markedly higher. Conclusions: Overall, these findings suggest that, despite recent declines, strategies are needed to further reduce SSB consumption, and particularly heavy intake, especially among NHB children where fruit drinks also are key source of SSBs.

Dietary Intake Changes in Response to a Sugar-Sweetened Beverage Reduction Trial for Various Supplemental Nutrition Assistance Program (SNAP) Eligibility Groups.

OBJECTIVE: To examine dietary intake differences resulting from a sugar-sweetened beverage reduction intervention by 3 Supplemental Nutrition Assistance Program (SNAP) participation groups: SNAP participants (n = 56), income-eligible nonparticipants (n = 30), and income-ineligible nonparticipants (n = 60). METHODS: Adults in southwest Virginia were enrolled in a 6-month behavioral trial. The researchers collected SNAP enrollment status and 3 24-hour dietary recalls at baseline and 6 months. Repeated-measures ANOVAs were used to assess differences in dietary intake among SNAP participation groups. RESULTS: No significant group × time differences were found for energy density, Healthy Eating Index scores, Healthy Beverage Index scores, or intake of total calories, added sugars, and sugar-sweetened beverages. However, several within-group improvements were noted: income-ineligible nonparticipants and SNAP participants improved in more areas compared with income-eligible nonparticipants, including intake of total calories, added sugars, and sugar-sweetened beverages. CONCLUSIONS AND IMPLICATIONS: This exploratory analysis suggests that the overall effectiveness of a sugar-sweetened beverage intake reduction intervention was not influenced by SNAP eligibility and participation status, because there were no significant group by time differences over the intervention. It is important to recognize for future programs that different approaches to improving dietary intake may be needed to match the characteristics of this audience better. This may be accomplished by attempting to decrease the disparity gap between income-eligible nonparticipants and those receiving SNAP or who are income ineligible through the use of programs such as SIPsmartER.
