Soda Consumption Among Adolescents: Implications for Low- and Middle-Income Countries

Consumption of carbonated soft drinks, fruits and vegetables and association with macroeconomic indicators: the analysis of students from seventy-four countries (2003-2015)

This study aimed to compare fruits and vegetables (FV), and carbonated soft drink (CSD) consumption among adolescents from seventy-four countries, according to macroeconomic indicators. This is an ecological study, developed with countries evaluated through the Global School-based Student Health Survey (2003-2014) and the National School Health Survey (PeNSE-Brazil, 2015). The percentages of students in each country who consumed CSD and FV daily and their association with the Human Development Index (HDI) and the Gross National Income per capita (GNIpc) were assessed. Scatter plots were constructed for each marker, and a multilevel model was tested to consider the effects of region in the associations. The overall prevalence of daily CSD consumption was 54·1 %. CSD consumption was positively associated with HDI and GNIpc through multilevel models, and Central and South America showed a considerable higher consumption compared with other regions. Overall, FV daily consumption was 67·9 % and 74·6 %, respectively, and no associations with macroeconomic indicators were found. The study shows concerning rates of CSD consumption among adolescents, and a trend of increased consumption with the improvement of the country's development and GNIpc. This points for the importance of public policies that regulate food and beverage industries to reduce CSD consumption and related co-morbidities among adolescents.

Correlation of Caries Prevalence, Oral Health Behavior and Sweets Nutritional Habits among 10 to 19-Year-Old Cluj-Napoca Romanian Adolescents

Background and objectives: The primary oral disease during adolescence is dental caries. Less is known about the caries prevalence, oral health behavior, and sweets nutritional habits in Romanian adolescents. The objective of this study was to assess the actual caries prevalence among Romanian adolescents in a representative area of Romania, Cluj, and to correlate with oral hygiene behaviors and dietary sugary foods intake. Materials and methods: We have done a cross-sectional study of 650 adolescents aged 10 to 19-years-old (average age 15.3 ± 2.8). We performed the oral dental examination according to the WHO methodology, calculated the number of decayed, missing (due to caries), and filled teeth (DMFT index), assessed the oral hygiene and dietary behaviors using a two-section valid questionnaire and statistically analyzed the interrelation between DMFT, oral hygiene and eating behaviors by multivariate statistical analysis. Results: (a) The caries prevalence in the adolescent population enrolled in the study was 95.5%; (b) the mean DMFT was 3.13 ± 2.0, without significant differences between the urban and rural adolescents (p = 0.253); lower in females than males (p < 0.050), (c) more than one third (33.7%, n = 219) of teenagers are seldom or never brush their teeth in the evening; (c) 40.6% of adolescents are missing the regular annual dental check-ups leading to an increased DMFT as shown in the multivariate analysis (p = 0.038); and (d) there is an increased prevalence of caries with age (p = 0.020), and with sugary sweetened beverages consumption (p = 0.028). Conclusions: Our study evidenced a persistent high caries prevalence in Romanian teenagers. Their dietary habits and irregular dental check-up were associated with the occurrence of dental conditions.
