Association between Cardiovascular Risk in Adolescents and Daily Consumption of Soft Drinks: a Brazilian National Study

Abstract Background: Cardiovascular risk in adolescence is a public health problem that has grown along with the increase in soft drink consumption. Objective: To investigate the association between cardiovascular risk factors and daily consumption of soft drinks in Brazilian adolescents. Methods: We conducted a cross-sectional, national, school-based study of 36,956 Brazilian adolescents aged 12 to 17 years. Daily soft drink consumption was estimated using a 24-hour dietary recall. Cardiovascular risk was categorized as overweight, obesity, hypertension, hyperglycemia, and dyslipidemia. The survey command of Stata 14.0® was used to analyze data from a complex sample. The chi-square test was used to assess differences in soft drink consumption and other variables in the descriptive analysis. The odds ratio of cardiovascular risk factors and their respective 95% confidence intervals were estimated, considering sociodemographic and behavioral variables in the Mantel-Haenszel model. Statistical significance was set at p < 0.05. Results: Daily consumption of soft drinks was common among adolescents. A daily serving ≥ 450 mL was significantly associated with overweight and hypertension. Results associated with the consumption of regular soft drinks show the possibility of reverse causality. Consumption of diet soft drinks in adolescence should be considered a cardiovascular risk factor. Conclusion: Daily consumption of soft drinks can be understood as a relevant risk factor in the epidemiological scenario. Improper eating habits are multifactorial in nature and need to be better understood in the context of adolescent health and further explored in national surveys.

Relação entre renda e consumo alimentar habitual de β-caroteno, vitamina C e vitamina E de crianças / The relationship between income and children's habitual consumption of β-carotene, vitamin C and vitamin E in food / Relación entre el ingreso y el consumo habitual de β-caroteno, vitamina C y vitamina en niños

Objetivo Analisar a relação entre renda e consumo alimentar de b-caroteno, vitamina C e vitamina E em crianças na cidade de João Pessoa, Brasil. Método Foram avaliadas 183 crianças com idade entre 2 e < 10 anos, em uma amostra representativa estratificada por níveis de renda da população de João Pessoa. O instrumento de pesquisa consistiu de questionários que abordaram aspectos sócio-econômicos, demográficos, antropométricos e de consumo alimentar. Analisou-se os resultados com o software R, por meio da estatística descritiva e inferencial (correlação e regressão). Resultados Observou-se predomínio do gênero masculino (55 por cento), das classes de renda E (até U.S. $ 428,64) e C (> U.S. $ 622,31-U.S. $ 2,682.93) e de mães que estudaram nove anos ou mais. Quanto à ingestão de vitaminas, houve baixa inadequação de vitamina C (8 por cento) e inadequação elevada de vitamina E (59 por cento), sendo esta última mais freqüente na faixa etária de 4-8 anos (33 por cento das crianças). Houve uma correlação inversa entre renda familiar e consumo energético (r=-0,1525, p <0,05) e entre renda e consumo de vitamina E (r =-0,3, p <0,05). As relações entre renda e escolaridade materna (p <0,05), renda e consumo de b-caroteno e renda e consumo de vitamina C (r=0,33 e r=0,28, respectivamente, p <0,05) foram significativamente positivas. Conclusão Concluiu-se que o consumo das vitaminas antioxidantes é positivamente relacionado com a renda familiar, em relação à vitamina C e b-caroteno e negativamente em relação à vitamina E e calorias.

Objective Examining the relationship between family income and daily b-carotene, vitamin C and vitamin E consumption amongst children in the city of João Pessoa / PB, Brazil. Method One hundred and eighty-three children aged 2 to <10 years were evaluated, in a sample stratified by income level which was representative of the population of Joao Pessoa. The research instrument consisted of questionnaires addressing socio-economic, demographic, epidemiological, anthropometric and food consumption variables. The results were analysedby using R software, using descriptive (mean, median, standard-deviation, simple and relative frequency and percentage) and inferential statistics (correlation and regression). Results Participants were predominantly male (55 percent) from income classes E (up to US$ 428.64) and C (> US$ 622.31-US$ 2,682.93) and mothers who had studied for nine years or more. Regarding vitamin intake, there was low vitamin C inadequacy (8 percent) and high vitamin E inadequacy (59 percent), the latter being more frequent in the 4-8 year-old age group (33 percent of children). There was an inverse correlation between income and energy intake (r=-0.1525, p<0.05) and between income and vitamin E consumption (r=-0.3, p<0.05). The relationship between income and maternal education (p<0.05), between income and b-carotene consumption and between income and vitamin C consumption was significantly positive (r=0.33 and r=0.28, respectively, p<0.05). Conclusion It was concluded that consuming vitamins having antioxidant properties was positively related to family income regarding vitamin C and b-carotene and negatively related regarding vitamin E and calories.

Prevalence and anthropometric predictors of high blood pressure in schoolchildren from João Pessoa - PB, Brazil.

BACKGROUND: Arterial hypertension (AH) belongs to the group of cardiovascular diseases with the highest mortality in the world and its onset can occur in childhood. OBJECTIVE: To evaluate the prevalence of high blood pressure (BP) in schoolchildren from public schools and its association with anthropometric indicators. METHODS: The present was a cross-sectional study, consisting of a random sample of 750 schoolchildren aged 6 to 9 years from public schools of the city of Joao Pessoa, state of Paraiba, Brazil. The data were collected by a previously trained team. BP was measured by auscultation, using a stethoscope and an aneroid sphygmomanometer. The collected anthropometric data were weight, height and abdominal circumference. Chi-square and Student's t association tests were used to compare means, both with a level of significance of 5%. Three logistic regression models were constructed, correlating high BP with the anthropometric variables to find a better prediction model. RESULTS: The prevalence of high BP levels was 13.6%. The body mass index (BMI) variable presented a significant association with the increase in BP levels (p < 0.0001) and a higher odds ratio (OR = 1.17). The increase in the BP levels also occurred with the increase in weight (p < 0.0001) and abdominal circumference (p < 0.0001). CONCLUSION: The identified association between excess weight with high BP levels emphasizes the need for intervention and for nutritional status control measures, such as dietary education programs aimed at the prevention and treatment of obesity as a risk factor for cardiovascular diseases in the pediatric and older age ranges.
