Association between intake of soft drinks and testicular function in young men

Is intake of sugar-sweetened beverages (SSB) or artificially sweetened beverages (ASB) associated with testicular function in young men? Among young men unaware of their semen quality and reproductive hormone levels, intake of SSBs was associated with lower sperm concentration, lower total sperm count, and a lower ratio of serum inhibin-B/FSH. SSBs may adversely impact testicular function, but results are not consistent across studies. Moreover, the associations of ASB, energy-drinks or fruit juices with testicular function are unclear. Young healthy men and unselected for fertility status men enrolled in a cross-sectional study between 2008 and 2017. A total of 2935 young (median age: 19 years) men enrolled in the study. Intake of SSBs, ASBs, fruit juices, and energy-drinks was assessed with a validated food frequency questionnaire. Testicular function was assessed through conventional semen quality parameters (semen volume, sperm concentration, total count, motility and morphology), testicular volume assessed with ultrasound, and serum reproductive hormone concentrations (total testosterone, free testosterone, E2, inhibin-B, LH, FSH, sex hormone-binding globulin) were measured. In multivariable-adjusted analyses, men in the highest category of SSB intake (median: 1.1 servings (∼220 ml)/day) had a 13.2 million/ml lower median sperm concentration (95% CI: -21.0, -5.5) than non-consumers. A similar pattern was observed with total sperm count (-28 million (95% CI: -48, -9)), serum inhibin-B (-12 pg/ml (95% CI: -21, -4)), and inhibin-B/FSH ratio (-9 (95% CI: -18, 0)). The adjusted median difference in sperm concentration and inhibin-B associated with increasing SSB intake by 1 serving (∼200ml)/day at the expense of water was -3.4 million sperm/ml (95% CI: -5.8, -1.0) and -7 pg/ml (95% CI: -11, -3), respectively. Inferring causality is limited owing to the cross-sectional design. We adjusted for a number of potential confounders but cannot exclude that unmeasured lifestyle and behavior associated with soft drink intake is associated with testicular function in these young men. In the largest study to date, intake of SSBs was associated with lower sperm concentration, total sperm count, and serum inhibin-B/FSH ratio, consistent with a direct suppressive effect of SSB intake on testicular function among otherwise healthy men, potentially affecting fertility. However, the observed association between higher SSB intake and lower semen quality does not necessarily imply a decrease in fertility.

Parental knowledge of dental erosion and erosion-related risk factors in children.

Dental erosion in children has been steadily on the increase in recent years. This is mainly due to the contemporary eating habits of the new generations and their upbringing from an early age to prefer foods and beverages with high acid content. To study the knowledge of parents about dental erosion and the most common risk factors associated with it. Data were gathered through a direct individual questionnaire administered to the parents of children aged 3 to 5 years. The results were analyzed by descriptive statistics and the Pearson chi-squared test for independence using SPSS 19. A large proportion of respondents (68.5%) stated that they knew what dental erosion was. Most of them (77.4%) were aware of the detrimental effect of carbonated beverages. In contrast, only 23.8% were aware of the potentially harmful effect of excessive consumption of citrus fruits, and only 31.9% of parents considered the impact of excessive intake of fruit juices. 16.1% of the participants were informed about the erosive potential of some medicines such as vitamin C. Nearly half of the parents (46.6%) found vigorous tooth brushing damaging. Despite the high self-esteem, a low percentage of the respondents were actually aware of the most common risk factors for dental erosion in children.

Using a translational research paradigm to investigate dietary intake of fruit juice on per- and polyfluoroalkyl substances (PFAS) concentrations

BACKGROUND AND AIM: Certain fruit juices, such as apple juice (AJ), contain bioactive molecules that can impair intestinal drug absorption through inhibition of transporter Organic Anion Transporting Polypeptide 2B1 (OATP2B1). Because some PFAS have been shown to be OATP2B1 substrates, we used a translational research paradigm to explore our hypothesis that higher fruit juice intake is associated with lower PFAS concentrations. METHODS: Female C57Bl/6 mice were administered perfluorooctane sulfonic acid (PFOS, 5 mg/kg) in buffer or in 4x AJ concentrate, with blood and tissues collected 5 hours after administration. Tissue PFOS was extracted and quantified by LC-MS. Epidemiologic analysis was conducted on 345 adolescents aged 12-19 years and 1,458 adults aged 20-80 years using the National Health and Nutrition Examination Study (NHANES), 2013 - 2014 cycle. Pure (100%) fruit juice intake was assessed by 24h dietary recall. Log-2 transformed serum concentrations of PFOS, perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS) were evaluated. Multivariable regression models were used to assess changes in PFAS concentrations in relation to dietary intake of juice, adjusting for covariates. RESULTS:In mice, 4x AJ co-administration decreased PFOS concentrations in blood, liver, kidney, and brain 5 hours after administration, indicating that 4x AJ can inhibit or delay PFOS absorption. Intake of pure fruit juice more than 1 time in the previous 24h was associated with a 15% (95%CI: -28%, -1%) reduction in serum PFOA concentration compared with no intake of juice among adolescents. No associations were observed between fruit juice intake and PFAS concentrations in adults. CONCLUSIONS:Combining experimental and epidemiological data, fruit juice consumption might lower PFAS burden. More research is needed to elucidate the effect of fruit juice consumption on PFAS concentrations in humans across age groups. KEYWORDS: PFAS, juice, translational, exposure reduction

Fruit and Vegetable Intake and Barriers to Their Consumption among University Students in Kuwait: A Cross-Sectional Survey.

Data on fruit and vegetable (F/V) consumption and barriers to their intake by Kuwait college students are needed for health promotional activities to curtail obesity and related comorbidities prevalent in Kuwait. This study employed a cross-sectional survey aimed at assessing the median F/V intake in a sample of Kuwait University students to determine its relationship with gender, body weight, college affiliation, and family monthly income and to explore perceived barriers to eating F/V. The median total F/V intake was 2.06, and the median intake of F/V without fries was even lower. Significant gender differences were found in intakes of fruit juice and the percentage of juice from fruit intake, with males consuming more servings per day compared to females. Male students were found to consume proportionately more fried potatoes of total vegetable intake when compared to females, whereas female students were found to consume more vegetables without fries than males. Taste, inconvenience, and lack of knowledge on F/V intake recommendations and preparation methods were among the main barriers to consuming more F/V. College students require encouragement to consume more F/V through targeted campaigns to increase awareness of recommendations, health benefits, and ways to incorporate F/V in their daily diet.

Longitudinal associations of fruit juice intake in infancy with DXA-measured abdominal adiposity in mid-childhood and early adolescence

Excessive abdominal adiposity is associated with health risks in children and adults. Higher consumption of fruit juice and other sources of fructose has been shown to promote weight gain and specifically visceral adiposity in adulthood. We aimed to examine the longitudinal associations of fruit juice intake in infancy with visceral adiposity in mid-childhood and early adolescence. We analyzed data from 783 participants in Project Viva, a US prebirth cohort. Our exposure was fruit juice intake at 1 y old. We measured visceral adipose tissue (VAT), subcutaneous abdominal adipose tissue (SAAT), and total abdominal adipose tissue (TAAT) in mid-childhood (mean age 7.8±0.7 y) and early adolescence (13±0.8 y) using DXA. We examined longitudinal associations of fruit juice intake at 1 y with VAT, SAAT, and TAAT area sex-specific standard deviation scores (SDSs) in mid-childhood and early adolescence using linear mixed models. We adjusted for child age at outcome, sex, race/ethnicity, age and BMI z-score at 1 y-questionnaire, maternal prepregnancy BMI, level of education, and prenatal sugar-sweetened beverage intake, paternal BMI, and median household income at birth. After adjusting for child and parental covariates, each serving (120 mL) per day of fruit juice intake at 1 y was associated with persistently greater VAT area SDS (β = 0.08; 95% CI: 0.03, 0.13) at both timepoints in boys and girls. The association of fruit juice intake with VAT appeared stronger than that with SAAT (β = 0.05; 95% CI: 0.00, 0.09) and TAAT (β = 0.05; 95% CI: 0.01, 0.10). Higher fruit juice intake in infancy was associated with greater abdominal adiposity, particularly VAT, in mid-childhood and early adolescence. Our findings support limiting fruit juice intake in infancy, which can have later impact on visceral adiposity in childhood and adolescence.Clinical Trial Registry number: NCT02820402 (https://clinicaltrials.gov/ct2/show/NCT02820402).

P97 Reducing Obesogenic Behaviors Through a Culturally-Tailored Family-Based Program: “Abriendo Caminos”

<h3>Introduction</h3> Hispanic children in the U.S. exhibit the highest rates of obesity compared to other racial/ethnic groups. Effective interventions to reduce the burden of this growing epidemic are needed. Obesity prevention interventions can improve weight outcomes by targeting modifiable lifestyle factors such as dietary patterns and physical activity. Furthermore, there is evidence that culturally-tailored interventions increase fruit and vegetable consumption and decrease sugar-sweetened beverage (SSB) consumption among Hispanic children. <h3>Objective</h3> To evaluate the effect of Abriendo Caminos 2 (AC2) on Hispanic children's dietary behaviors. <h3>Methods</h3> AC2 is a multi-state randomized-control trial that aims to prevent childhood obesity among Hispanic families by providing culturally-tailored nutrition, physical activity, and family wellness education. Families of Mexican or Puerto Rican origin with a child between the ages of 6–18 years were recruited from Illinois, California, Iowa, and Texas. Parents' reported their child's dietary intake of SSB, fruit juice, fruits, French fries, vegetables, fast food, sweets, and salty snacks using items from the U.S. Department of Education's Early Childhood Longitudinal Study, Birth Cohort protocol. Pre/post dietary changes were evaluated using Generalized Estimating Equation models adjusted for site, child sex, age, and mother's education using SAS 9.4 (SAS Institute, Cary, NC, USA). <h3>Results</h3> Children randomized to the intervention arm reduced their consumption of SSB (OR 0.35, 95% CI 0.15, 0.84, <i>P</i> = 0.003), fast food (OR 0.53, 95% CI 0.30, 0.92, <i>P</i> = 0.03), and increased consumption of vegetables (OR 1.95, 95% CI 1.13, 3.36, <i>P</i> = 0.02) after 6 weeks of participating in the program. Children in the control group reportedly decreased SSB consumption frequency (OR 0.40, 95% CI 0.17, 0.97, <i>P</i> = 0.04). There were no changes in the frequency of consumption of the other food items for either group. <h3>Conclusion</h3> Culturally-tailored family-based interventions can help improve dietary behaviors among Hispanic children. Future research should address methods to help Hispanic children transition short-term changes into lifestyle habits.

Beverage Intake and the Risk of Gestational Diabetes Mellitus: The SECOST.

The contribution and impact of beverage intake to total nutrient and energy intake may be substantial. Given the link between lifestyle, diet, and the risk of pregnancy complications, this study investigated the association between the quantity and types of beverages with gestational diabetes mellitus (GDM) risk. The study included 452 women from the Seremban Cohort Study (SECOST). The mean energy by beverage intake was 273 ± 23.83 kcal/day (pre-pregnancy), 349 ± 69.46 kcal/day (first trimester) and 361 ± 64.24 kcal/day (second trimester). Women significantly increased intake of maternal milks and malted drinks, but significantly reduced the intake of carbonated drinks and other drinks from before until the second trimester of pregnancy. For chocolate drinks, carbonated drinks, and soy milk, women increased intake from pre-conception to the first trimester, but reduced their intake from the first to the second trimester. While higher intake of cultured-milk drinks was associated with an increased risk of GDM, higher fruit juice intake was associated with a lower risk of GDM. However, these associations were only observed for intake prior to pregnancy and during the first trimester. Further research is needed to corroborate these findings and investigate the contributions of different beverages to overall diet quality as well as adverse health outcomes during pregnancy.

Associations Between Fruit Intake and Risk of Diabetes in the AusDiab Cohort.

ContextFruit, but not fruit juice, intake is inversely associated with type 2 diabetes mellitus (T2DM). However, questions remain about the mechanisms by which fruits may confer protection.ObjectiveThe aims of this work were to examine associations between intake of fruit types and 1) measures of glucose tolerance and insulin sensitivity and 2) diabetes at follow-up.MethodsAmong participants of the Australian Diabetes, Obesity and Lifestyle Study, fruit and fruit juice intake was assessed by food frequency questionnaire at baseline. Associations between fruit and fruit juice intake and 1) fasting plasma glucose, 2-hour postload plasma glucose, updated homeostasis model assessment of insulin resistance of β-cell function (HOMA2-%β), HOMA2 of insulin sensitivity (HOMA2-%S), and fasting insulin levels at baseline and 2) the presence of diabetes at follow-up (5 and 12 years) were assessed using restricted cubic splines in logistic and linear regression models.ResultsThis population of 7675 Australians (45% males) had a mean ± SD age of 54 ± 12 years at baseline. Total fruit intake was inversely associated with serum insulin and HOMA2-%β, and positively associated with HOMA2-%S at baseline. Compared to participants with the lowest intakes (quartile 1), participants with moderate total fruit intakes (quartile 3) had 36% lower odds of having diabetes at 5 years (odds ratio, 0.64; 95% CI, 0.44-0.92), after adjusting for dietary and lifestyle confounders. Associations with 12-year outcomes were not statistically significant.ConclusionA healthy diet including whole fruits, but not fruit juice, may play a role in mitigating T2DM risk.

Sugar-Sweetened Beverages, Fruit Juice, and Low-Calorie Beverages, and All-Cause Mortality Risk Among Dutch Adults: The Lifelines Cohort Study Within the SWEET Project

ObjectivesTo examine prospective associations between intakes of sugar-sweetened beverages (SSB), fruit juice, and low-calorie beverages (LCB), and all-cause mortality among Dutch adults participating in the Lifelines Cohort Study. MethodsA total of 118,439 participants aged 45 ± 13 years (60% women) were included in a prospective cohort analysis. Dietary intake at baseline was assessed using an extensive semi-quantitative food frequency questionnaire (FFQ). Uni- and multivariate Cox proportional hazard regression analyses, including substitution analyses, were performed adjusted for demographics, self-reported diseases and lifestyle, and dietary factors. The association was modelled continuously in each 1 glass (or 150 mL)/day intake increment and in four categories of each beverages intake (no intake, ≤2 glass/week, >2--<7 glass/week, and ≥1 glass/day). ResultsOf the total participants, 63% were SSB consumers, 76% were fruit juice consumers, and 56% were LCB consumers. The median intake among consumers was 0.4 [0.2–1.0] glass/day for SSB, 0.3 [0.1–0.7] glass/day for fruit juice, and 0.5 [1.2–1.1] glass/day for LCB. During a follow-up period of 8.3 [7.5–9.3] y, 2,023 (1.8%) deaths were recorded. Compared to no intake, ≥1 glass SSB/day was associated with a higher risk of mortality (HR 1.24, 95% CI 1.05, 1.46), whereas LCB intake was not associated with all-cause mortality risk. Theoretical replacement of 1 glass/day of SSB with the same amount of LCB was associated with a lower risk of all-cause mortality (HR 0.90, 95% CI 0.83, 0.98). Finally, compared to no intake, moderate fruit juice intake (≤2 glass/week and >2--<7 glass/week) was inversely associated with all-cause mortality (HR 0.80, 95% CI 0.72, 0.90 and HR 0.85, 95% CI 0.76, 0.95 respectively). ConclusionsSSB intake was associated with a higher risk of all-cause mortality in the general Dutch adult population, whereas moderate fruit juice intake showed the opposite. Replacing SSB with LCB was associated with a lower risk of all-cause mortality Funding SourcesThis EU-project under the acronym “SWEET” has received funding from the European Union’s Horizon 2020 research and innovation programme.

The Influence of Rurality on Fruit and Vegetable Intake and BMI: Findings in Mississippi Are Not Consistent with Those at the National Level.

Sixty percent of Americans have at least one chronic disease that is both diet-related and preventable. Those living in rural areas often experience a greater burden of disease than those who live near a city center. The purpose of this study is to determine the influence of rurality on fruit and vegetable (FV) consumption and BMI. Additionally, the study compares national results to those in Mississippi, a state with an aging population, and high rates of poverty, rurality, poor diet, and obesity. Data utilized were from the 2017 Behavioral Risk Factor Surveillance System. One-way analyses of covariance were performed to determine impact of rurality on nutritional intake and BMI, while controlling for age, income, education, race, and the presence of children in the home. At the national level, rurality had a significant impact on BMI, and the daily intake of fruit juice, fruits, dark green vegetables, French fries, potatoes, other vegetables, and total daily vegetable intake. BMI and nutritional intake of those living in Mississippi was significantly poorer than those living in other states. More research is needed to determine how to best facilitate access to healthy FVs for those living in rural communities.

Associations between dietary patterns and the incidence of total and fatal cardiovascular disease and all-cause mortality in 116,806 individuals from the UK Biobank: a prospective cohort study

BackgroundTraditionally, studies investigating diet and health associations have focused on single nutrients. However, key nutrients co-exist in many common foods, and studies focusing solely on individual nutrients may obscure their combined effects on cardiovascular disease (CVD) and all-cause mortality. We aimed to identify food-based dietary patterns which operate through excess energy intake and explain high variability in energy density, free sugars, saturated fat, and fiber intakes and to investigate their association with total and fatal CVD and all-cause mortality.MethodsDetailed dietary data was collected using a 24-h online dietary assessment on two or more occasions (n = 116,806). We used reduced rank regression to derive dietary patterns explaining the maximum variance. Multivariable Cox-proportional hazards models were used to investigate prospective associations with all-cause mortality and fatal and non-fatal CVD.ResultsOver an average of 4.9 years of follow-up, 4245 cases of total CVD, 838 cases of fatal CVD, and 3629 cases of all-cause mortality occurred. Two dietary patterns were retained that jointly explained 63% of variation in energy density, free sugars, saturated fat, and fiber intakes in total. The main dietary pattern was characterized by high intakes of chocolate and confectionery, butter and low-fiber bread, and low intakes of fresh fruit and vegetables. There was a positive linear association between the dietary pattern and total CVD [hazard ratio (HR) per z-score 1.07, 95% confidence interval (CI) 1.04–1.09; HRtotal CVD 1.40, 95% CI 1.31–1.50, and HRall-cause mortality 1.37, 95% CI 1.27–1.47 in highest quintile]. A second dietary pattern was characterized by a higher intakes of sugar-sweetened beverages, fruit juice, and table sugar/preserves. There was a non-linear association with total CVD risk and all-cause mortality, with increased risk in the highest quintile [HRtotal CVD 1.14, 95% CI 1.07–1.22; HRall-cause mortality 1.11, 95% CI 1.03–1.19].ConclusionsWe identified dietary patterns which are associated with increased risk of CVD and all-cause mortality. These results help identify specific foods and beverages which are major contributors to unhealthy dietary patterns and provide evidence to underpin food-based dietary advice to reduce health risks.

Food consumption pattern and dietary diversity of a vegetarian population in Ghana.

This study examined the food consumption pattern and dietary diversity of a vegetarian population in the Greater Accra Region of Ghana. A cross-sectional study was employed to examine the nutritional status of four (4) vegetarian groups in the Greater Accra Region of Ghana. One hundred and twenty-two (122) vegetarians were recruited using the total enumeration technique. Food consumption pattern and dietary diversity were assessed using a validated qualitative food frequency questionnaire and a 24-hour dietary recall, respectively. Dietary diversity was calculated using the FAO guidelines. Sixty eight percent (68%) of the vegetarians reported daily intakes of vegetable protein. Majority of the vegetarians (80.6%) reported daily intakes of cereals and grains while 54% reported daily intakes of tubers. Eighty two percent (82%) and 72% of the vegetarians consumed vegetables and fruits on daily basis respectively. A few of the vegetarians (29%) reported daily intakes of fruit juices. Soft drinks, deep fried foods and fast foods were occasionally consumed. About 40.3% of the vegetarians obtained a dietary diversity score of four (4). Majority of them (68.9%) had low dietary diversity. The vegetarians had low dietary diversity which may lead to inadequate nutrient intakes. Thus, there is the need for nutrition-related professionals to give appropriate information on a vegetarian diet and educate vegetarians to include a variety of foods in their diet. None declared.

Fruit and Vegetable Intake and Mortality: Results From 2 Prospective Cohort Studies of US Men and Women and a Meta-Analysis of 26 Cohort Studies.

The optimal intake levels of fruit and vegetables for maintaining long-term health are uncertain. We followed 66 719 women from the Nurses' Health Study (1984-2014) and 42 016 men from the Health Professionals Follow-up Study (1986-2014) who were free from cardiovascular disease (CVD), cancer, and diabetes at baseline. Diet was assessed using a validated semiquantitative food frequency questionnaire at baseline and updated every 2 to 4 years. We also conducted a dose-response meta-analysis, including results from our 2 cohorts and 24 other prospective cohort studies. We documented 33 898 deaths during the follow-up. After adjustment for known and suspected confounding variables and risk factors, we observed nonlinear inverse associations of fruit and vegetable intake with total mortality and cause-specific mortality attributable to cancer, CVD, and respiratory disease (all Pnonlinear<0.001). Intake of ≈5 servings per day of fruit and vegetables, or 2 servings of fruit and 3 servings of vegetables, was associated with the lowest mortality, and above that level, higher intake was not associated with additional risk reduction. In comparison with the reference level (2 servings/d), daily intake of 5 servings of fruit and vegetables was associated with hazard ratios (95% CI) of 0.87 (0.85-0.90) for total mortality, 0.88 (0.83-0.94) for CVD mortality, 0.90 (0.86-0.95) for cancer mortality, and 0.65 (0.59-0.72) for respiratory disease mortality. The dose-response meta-analysis that included 145 015 deaths accrued in 1 892 885 participants yielded similar results (summary risk ratio of mortality for 5 servings/d=0.87 [95% CI, 0.85-0.88]; Pnonlinear<0.001). Higher intakes of most subgroups of fruits and vegetables were associated with lower mortality, with the exception of starchy vegetables such as peas and corn. Intakes of fruit juices and potatoes were not associated with total and cause-specific mortality. Higher intakes of fruit and vegetables were associated with lower mortality; the risk reduction plateaued at ≈5 servings of fruit and vegetables per day. These findings support current dietary recommendations to increase intake of fruits and vegetables, but not fruit juices and potatoes.

Associations between fruit juice and milk consumption and change in BMI in a large prospective cohort of U.S. adolescents and preadolescents.

There are concerns that fruit juice and milk contribute to childhood obesity. Determine the relationship between fruit juice and milk intakes and body mass index (BMI) change among preadolescents/adolescents. Participants aged 9 to 16 years old from the Growing Up Today Study II completed surveys including validated food frequency questionnaires in 2004, 2006 and 2008. The contributions of one serving of juice or milk to total energy intake and 2-year change in BMI were evaluated using multiple linear regression. Additional analyses were conducted with subgroups of juice (orange juice and other fruit juice) and milk (low fat and high fat). Missing values for BMI were imputed using a multiple imputation approach, after which data from 8173 participants and 13 717 2-year interval observations were analysed. Baseline fruit juice consumption was inversely associated with BMI change in girls (β=-.102 kg/m2 , SE=0.038, P value=.008) but not boys after controlling for race, age, baseline BMI, and baseline and 2-year changes in total energy intake and physical activity. Orange juice was inversely associated with BMI change among girls (β=-.137 kg/m2 , SE=0.053, P value=.010) while other fruit juice, low fat and high fat milk were not associated with BMI change. Orange juice was inversely associated with 2-year BMI change among preadolescent/adolescent girls but not boys and there were no significant associations with other juices or milk among either gender.

Association of infant diet with subsequent obesity at 2-5years among children exposed to gestational diabetes: the SWIFT study.

This longitudinal analysis evaluated the independent and joint associations of any breastfeeding (BF) or exclusive BF (EBF) and intake of sugar-sweetened beverages (SSBs) and 100% fruit juice from birth to 1year with subsequent overweight and obesity among young children exposed to gestational diabetes (GDM). The analysis utilised prospectively collected data from participants enrolled in the Study of Women, Infant Feeding and Type 2 Diabetes after GDM (SWIFT); 1035 pregnant women (20-45years) diagnosed with GDM, of whom 75% were of Black, Hispanic or Asian race and ethnicity. Mother-infant dyad characteristics and infant dietary intake were assessed via research protocols at in-person examinations, telephone interviews and monthly mailed surveys from birth to 1year. Child weight, length and height were obtained from electronic health records at birth (2008-2011) and ages 2-5years (2010-2016) to classify BMI percentile groups (n = 835). Adequate BF (≥6months), adequate EBF duration (≥6months), and SSB and 100% fruit juice intake in the first year were independently associated with child obesity at ages 2-5years (all p < 0.05). Compared with children with adequate EBF and no intake of SSB or 100% fruit juice, those with adequate EBF and intake of 100% fruit juice and/or SSBs had a four- to fivefold higher odds of obesity (aOR 4.2, 95% CI:1.6, 11.2 for 100% fruit juice; aOR 4.5, 95% CI:1.4, 8.5 for fruit juice or SSBs; and aOR 4.7, 95% CI:1.4, 15 for SSBs; all p < 0.01), while those with inadequate EBF (<6months) and intake of 100% fruit juice and/or SSBs had a six- to 12-fold higher odds of obesity (aOR 6.4, 95% CI:2.4, 17.2 for fruit juice; aOR 6.6, 95% CI:2.7, 14.8 for fruit juice or SSBs; and aOR 12.2, 95% CI:4.3, 25 for SSBs; all p < 0.001). Compared with children with adequate BF and no intake of SSB or 100% fruit juice, those with adequate BF and intake of 100% fruit juice and/or SSBs had a threefold higher odds of obesity (aOR 3.1, 95% CI:1.1, 7.3 for fruit juice; aOR 3.3, 95% CI:1.3, 8.3 for fruit juice or SSBs; and aOR 3.4, 95% CI:1.3, 8.5 for SSBs; all p < 0.05), while those with inadequate BF (<6months) and intake of 100% fruit juice and/or SSB were associated with five- to tenfold higher odds of obesity (aOR 4.8, 95% CI:2.3, 12.2 for fruit juice; aOR 6.0, 95% CI:2.5, 12.8 for fruit juice or SSBs; aOR 9.5, 95% CI:3.7, 15.1 for SSBs; all p < 0.05). This is the first study to prospectively evaluate the relation of BF or EBF duration and intake of SSB and 100% fruit juice during the first year of life with subsequent obesity in children exposed to GDM. Adequate BF or EBF combined with avoidance of SSB and 100% fruit juice during early infancy may ameliorate future child obesity in this high-risk population.

A Comparison of Weight-Related Behaviors of Hispanic Mothers and Children by Acculturation Level.

Hispanic mothers and children in the United States experience a high prevalence of obesity, which may be affected by maternal acculturation level. Little is known about the association of acculturation on weight-related behaviors. This study describes differences in weight-related behaviors by acculturation level of Hispanic mothers residing in the U.S. and compares them to behaviors of White mothers. Acculturation level was determined using personal acculturation and acculturation environment variables. Cluster analysis of acculturation variables identified three groups of Hispanic mothers: low personal and environmental acculturation (n = 46), high personal and low environmental acculturation (n = 65), and high personal and environmental acculturation (n = 38). Results indicate that, compared to White mothers (n = 340), the least acculturated cluster of Hispanic mothers tended to model physical activity less often and the most acculturated exerted more pressure on children to eat. Mothers in the least acculturated cluster tended to rate children’s health status lower, indicate that children had greater fruit juice and less milk intakes, have more meals in locations associated with less healthy meals, and have the least space and supports for physical activity. Findings highlight relationships between maternal acculturation level and weight-related behaviors and suggest strategies for helping acculturating Hispanic mothers create healthier lifestyles and home environments.

Consumption of sugar-sweetened beverages and fruit juice and human cancer: a systematic review and dose-response meta-analysis of observational studies

Background: Several epidemiological studies have assessed the association of sugary drinks consumption with cancer, but the results remain controversial.Objective: We performed this analysis to evaluate possible causal relationship between sugary drinks consumption and cancer risk and mortality.Methods: We searched PubMed, Embase, and Web of Science databases in English. Observational studies evaluating the association of sugary drinks intake with cancer were included. Random-effects meta-analysis was used to calculate the risk estimates.Results: A total of 71 observational articles with 32 case-control and 39 cohort studies were included in the meta-analysis. 60 addressed cancer risk, and 11 reported cancer mortality. Compared with the lowest level, the highest level of sugar-sweetened beverages (SSB) consumption showed an increased overall cancer risk (RR=1.12 95% CI: 1.06-1.19, P=0.000) and mortality (RR=1.07 95% CI: 1.01-1.14, P=0.029), and fruit juice intake showed a positive association with cancer risk in cohort studies (RR=1.06 95% CI: 1.01-1.11, P=0.013). Subgroup analyses based on cancer type indicated that risk of breast cancer, hepatocellular carcinoma, colorectal cancer, and prostatic cancer mortality had a positive association with SSB consumption. For dose-response analysis, evidence of a linear association was found between overall cancer risk and SSB or fruit juice consumption, and the risk increase by 4% for one servings/d increment in SSB intake and 14% in fruit juice.Conclusions: Our findings suggest the consumption of sugary beverages may increase the risk and mortality of cancer, especially risk of breast cancer, hepatocellular carcinoma, colorectal cancer, and prostatic cancer, and mortality of breast cancer, though the evidence was limited.

Long-Term Consumption of Anthocyanin-Rich Fruit Juice: Impact on Gut Microbiota and Antioxidant Markers in Lymphocytes of Healthy Males.

Polyphenols are considered protective against diseases associated with oxidative stress. Short-term intake of an anthocyanin-rich fruit juice resulted in significantly reduced deoxyribonucleic acid (DNA) strand-breaks in peripheral blood lymphocytes (PBLs) and affected antioxidant markers in healthy volunteers. Consequently, effects of long-term consumption of fruit juice are of particular interest. In focus was the impact on nuclear factor erythroid 2 (NFE2)-related factor 2 (Nrf2), the Nrf2-regulated genes NAD(P)H quinone oxidoreductase 1 (NQO-1) and heme oxygenase 1 (HO-1) as well as effects on the gut microbiota. In a nine-week placebo-controlled intervention trial with 57 healthy male volunteers, consumption of anthocyanin-rich juice significantly increased NQO-1 and HO-1 transcript levels in PBLs compared to a placebo beverage as measured by real-time polymerase chain reaction (PCR). Three Nrf2-promotor single nucleotide polymorphisms (SNPs), analyzed by pyrosequencing, indicated an association between individual Nrf2 transcript levels and genotype. Moreover, the Nrf2 genotype appeared to correlate with the presence of specific microbial organisms identified by 16S-PCR and classified as Spirochaetaceae. Furthermore, the microbial community was significantly affected by the duration of juice consumption and intake of juice itself. Taken together, long-term consumption of anthocyanin-rich fruit juice affected Nrf2-dependent transcription in PBLs, indicating systemic effects. Individual Nrf2 genotypes may influence the antioxidant response, thus requiring consideration in future intervention studies focusing on the Nrf2 pathway. Anthocyanin-rich fruit juice had an extensive impact on the gut microbiota.

Sugar-containing beverages and their association with risk of breast, endometrial, ovarian and colorectal cancers among Canadian women

BackgroundThe association of sugar containing beverages (SCBs) with risk of breast, endometrial, ovarian and colorectal cancers is unclear. Therefore, we investigated these associations in the Canadian Study of Diet, Lifestyle, and Health. MethodsThe study population comprised an age-stratified subcohort of 3185 women and 848, 161, 91 and 243 breast, endometrial, ovarian and colorectal cancer cases, respectively. We used Cox proportional hazards regression models modified for the case-cohort design to assess the associations of SCBs with risk of the aforementioned cancers. ResultsCompared to SCB intake in the lowest tertile, SCB intake in the highest tertile was positively associated with endometrial cancer risk (HRT3 vs T1 = 1.58, 95 % CI = 1.08−2.33 and 1.78, 95 % CI = 1.12−2.81 for overall and Type 1 endometrial cancer, respectively) and ovarian cancer (HRT3 vs T1 = 1.76, 95 % CI: 1.09−2.83). Fruit juice intake was also positively associated with risk of Type 1endometrial (HRT3 vs T1 = 1.63, 95 % CI = 1.03−2.60). After excluding women with diabetes or cardiovascular diseases, we also observed sugar-sweetened beverages (SSBs) intake in the highest tertile was associated with higher risk of Type 1 endometrial cancer (HR T3 vs T1 = 1.65; 95 % CI: 1.03−2.64). None of the beverages was associated with risk of breast or colorectal cancer. ConclusionWe conclude that, in this cohort, relatively high SCB intake was associated with higher risk of endometrial and ovarian cancers, but not of breast or colorectal cancers. Our findings also suggest that relatively high SSB and fruit juice intake are associated with higher risk of Type 1 endometrial cancer.

Ultrasound assessment of gastric emptying time after intake of clear fluids in children scheduled for general anesthesia-A prospective observational study.

While many clinics have changed their local regimen toward a more liberal policy regarding clear fluid fasting for general anesthesia, there is a lack of studies evaluating gastric emptying time in a clinical setting. Based on this and before implementation of a more liberal preoperative clear fluid fasting policy for children, we studied gastric emptying time of clear fluids in children and hypothesized that the mean gastric emptying time would be 1hour. Between March and December 2019, children scheduled for general anesthesia at our University Children's Hospital were enrolled in this prospective observational study. After overnight fasting, gastric emptying was examined by sonographic measurements of the gastric antral area before and 5, 15, 30, 45, and 60minutes after intake of water or fruit juice. Twenty-six children were enrolled in this study, and 24 aged 11 (range 4-17) years were included for statistical analysis. The median ingested fluid volume was 4.7 (range 1.8-11.8)mLkg-1 . The gastric antral area of the children initially increased and subsequently decreased after intake of clear fluids and correlated significantly with fasting time (r=-0.55, P<.0001). After 1hour, the gastric antral area had returned to the baseline level in 20 children but not in four children with a fluid intake >5mLkg-1 . There was no difference in the gastric antral area between water and fruit juice. Using a linear regression model, the calculated mean gastric emptying time of clear fluids was 52minutes. This study showed that the gastric emptying time of children after intake up to 5mLkg-1 clear fluids was <1hour in a clinical setting. These results support the more liberal fasting regimen favoring a 1-hour fasting time and suggest 5mLkg-1 as an upper limit for clear fluids (eg, water, sugared water or tea or diluted fruit juice) from 2hours to 1hour before induction of anesthesia in children.
