In this research it was found that the most frequently consumed caffeine drink by the student (men) JU is a tea and caffeinated drinks are most often consumed for thein taste. Processing research results also revelaed that caffeinated drinks have not a hight proportion of respondents it the drinking regime.

INTRODUCTION: Research has strongly linked increased consumption of sugar-sweetened beverages (SSBs) to obesity/overweight in youth. AIM: This study aims to: (1) examine SSB consumption rates in high school students nationwide, (2) explore association between SSB consumption and adiposity (overweight/obesity), (3) examine gender, racial/ethnic, and physical activity (PA) status differences in SSB consumption. METHODS: The Youth Risk Behavior Survey (YRBS)-2015 was employed in this study. Weighted percentages were used to examine differences in SSB consumption and adiposity prevalence by gender, race and PA status. Multivariate logistic regression was used to determine association between SSB consumption and adiposity. Adjusted and unadjusted odds ratios and 95% CIs were calculated. RESULTS: Overall, 20% of students drank sodas daily ≥ 1 times a day and about 14% drank sports drinks daily. More male students consumed both sodas and sports drinks than female students. Soda consumption was largest in the group with zero days PA (25%) and consumption of sports drinks was highest in the daily PA category (24%) than the other categories. Multivariate logistic regression revealed higher odds of obesity among male students as compared to female students (OR=1.7, 95% CI=1.4, 2.1) and among Hispanic students as compared to white students (OR=1.5, 95% CI=1.2, 1.8), after adjusting for all other covariates. Students who engaged in daily PA had lower odds of obesity than those who had no PA (OR=0.6, 95% CI=0.5, 0.8). There was no significant difference in the odds of obesity between those who consumed SSBs and those who did not. DISCUSSION: This study provides insight into SSB consumption trends in US adolescents by socio- demographic factors and PA status, as well as its association with adiposity. Male gender, certain racial minorities and lack of physical activity can potentially be responsible for greater SSB consumption. Sports drinks consumption is high even in physically active youth. Lack of association between SSB intake and adiposity may be due to the limited SSBs included.

Objective: This study aimed to assess the impact of in vitro erosion provoked by different cola-based drinks (Coke types), associated or not with toothbrushing, to bonding to enamel. Material and methods: Forty-six bovine enamel specimens were prepared and randomly assigned into seven groups (N=8): C- Control (neither eroded nor abraded), ERO-RC: 3x/1-minute immersion in Regular Coke (RC), ERO-LC: 3x/1-minute immersion in Light Coke (LC), ERO-ZC: 3x/1-minute immersion in Zero Coke (ZC) and three other eroded groups, subsequently abraded for 1-minute toothbrushing (EROAB-RC, EROAB-LC and EROAB-ZC, respectively). After challenges, they were stored overnight in artificial saliva for a total of 24 hours and restored with Adper Single Bond 2/Filtek Z350. Buildup coronal surfaces were cut in 1 mm2-specimens and subjected to a microtensile test. Data were statistically analyzed by two-way ANOVA/Bonferroni tests (a=0.05). Failure modes were assessed by optical microscopy (X40). The Interface of the restorations were observed using Confocal Laser Scanning Microscopy (CLSM). Results: All tested cola-based drinks significantly reduced the bond strength, which was also observed in the analyses of interfaces. Toothbrushing did not have any impact on the bond strength. CLSM showed that except for Zero Coke, all eroded specimens resulted in irregular hybrid layer formation. Conclusions: All cola-based drinks reduced the bond strength. Different patterns of hybrid layers were obtained revealing their impact, except for ZC. / This study was supported in part by grants given by the São Paulo Research Foundation (FAPESP), Process no. 2009/14986-0, and the National Council for Scientific and Technological Development (CNPq), Process no. 480038/2007-4.

<p>Various factors, including low levels of physical activity (PA), and high consumption levels of sugar-sweetened drinks (SD), have been implicated in the general increase of fat mass (FM) levels seen in youth. <b>Purpose</b>: To determine if a significant relationship exists between fat mass (FM) and physical activity (PA) or sugar-sweetened drink (SD), in boys and girls, using longitudinal analysis. <b>Methods</b>: 105 boys and 103 girls were assessed repeatedly during childhood and adolescence, for a maximum of 7 years. Height was measured annually, as was fat free mass (FFM) and FM estimated by dual X-ray absorptiometry (DXA). PA was evaluated bi-annually using a questionnaire for children (PAQ-C/A: 1 low, 5 high), and SD was assessed using a 24-hour dietary intake questionnaire completed 1-4 times/year. Years from peak height velocity were used as a biological age indicator. Random effects models were used to analyze the data, subsequent to log linearization of the FM variable since it was not initially normally distributed. <b>Results</b>: The constructed model, controlling for maturation, FFM, and adjusted energy intake, found no interaction effect between SD and PA (p>0.05). After removal of the interaction term from the model, SD was found to have no significant relationship (p>0.05) with FM of boys or girls. In contrast, PA level was found to have a significant relationship (p<0.05) with FM of males; but not with FM of females. <b>Conclusion</b>: The longitudinal models employed revealed a significant negative relationship between level of PA and FM in males but not females, after controlling for maturational status, body size and dietary energy intake. This finding lends support, to proponents of increasing PA in youth to control FM. Regarding SD and FM, the models employed showed no relationship. Future investigation with more complex models, accounting for more covariates, may be warranted in this area.</p>
