Evaluation of the Effects of Sugary Beverages on the Health of Adolescent Students in Guangxi Based on Health System Function Scores

Objective:To evaluate the health effects of sugary beverage consumption among adolescent students in Guangxi.Methods:In three cities of Guangxi(Nanning,Liuzhou,and Guilin),we investigated the consumption of sugary beverages by distributing a self-administered Functional Assessment Questionnaire of Life Health System and a Dietary Behavior Questionnaire(this paper analyzes only the part of sugary beverage consumption)to adolescent students in four schools,aiming to find out the general health status of the students and also to assess the effects of sugary beverages on the functional system health of adolescent students.Results:A total of 953 adolescent students between the ages of 14 and 24 were surveyed.Among them,46.17%consumed sugary beverages once a week;37.46%consumed them 2-3 times;11.52%consumed them more than 3 times;and 4.83%consumed them every day.The mean score of Functional Assessment Questionnaire of Life Health System was 32.There was a positive correlation between the frequency of consumption of sugary beverages and the overall systemic function assessment score(P<0.05),and the rank of the total score elevated by 0.314 times for each increase in the level of consumption.Compared to those who drink sugary beverages at least once a day,drinking them once a week showed a statistically significant difference(P<0.05).However,there was no statistically significant difference between drinking 2-3 times a week and more than 3 times a week(P>0.05).The correlation between consuming sugary beverages once a week and 2-3 times a week and endocrine system scores was also statistically significant(P<0.05).Conclusion:More than half of the students in the surveyed areas consumed sugary beverages two or more times a week,and the higher the frequency of consumption,the higher the scores of systemic function assessment.Health education on sugar reduction among adolescents should be strengthened.

Mixed methods evaluation of a randomized control pilot trial targeting sugar-sweetened beverage behaviors

This Excessive sugar-sweetened beverage (SSB) consumption and low health literacy skills have emerged as two public health concerns in the United States (US);however, there is limited research on how to effectively address these issues among adults. As guided by health literacy concepts and the Theory of Planned Behavior (TPB), this randomized controlled pilot trial applied the RE-AIM framework and a mixed methods approach to examine a sugar-sweetened beverage (SSB) intervention (SipSmartER), as compared to a matched-contact control intervention targeting physical activity (Move-More). Both 5-week interventions included two interactive group sessions and three support telephone calls. Executing a patient-centered developmental process, the primary aim of this paper was to evaluate patient feedback on intervention content and structure. The secondary aim was to understand the potential reach (i.e., proportion enrolled, representativeness) and effectiveness (i.e. health behaviors, theorized mediating variables, quality of life) of SipS- martER. Twenty-five participants were randomized to SipSmartER (n = 14) or MoveMore (n = 11). Participants’ intervention feedback was positive, ranging from 4.2 - 5.0 on a 5-point scale. Qualitative assessments reavealed several opportuneties to improve clarity of learning materials, enhance instructions and communication, and refine research protocols. Although SSB consumption decreased more among the SipS-martER participants (?256.9 ± 622.6 kcals), there were no significant group differences when compared to control participants (?199.7 ± 404.6 kcals). Across both groups, there were significant improvements for SSB attitudes, SSB behavioral intentions, and two media literacy constructs. The value of using a patient-centered approach in the developmental phases of this intervention was apparent, and pilot findings suggest decreased SSB may be achieved through targeted health literacy and TPB strategies. Future efforts are needed to examine the potential public health impact of a large-scale trial to address health literacy and reduce SSB.

Uncovering Consumer Mindsets Regarding Raw Beverages

Nutritional fads in the health and fitness world are constantly changing. Each new craze has its believers and critics. For the consumer, “what to believe” becomes a topic filled with uncertainty. This paper presents a systematic approach to understanding what consumers believe about the health messaging of “raw beverages”. The paper presents both substantive results from US consumers, as well as demonstrates a general approach by which researchers can more deeply understand the consumer mind with respect to the specifics of health and wellness issues.

Health effects of fruit juices and beverages with varying degrees of processing

The degree of processing is rarely considered an independent factor in the health effects of fruit juices and beverages(FJBs)consumption.In fact,the consumption of ultra-processed foods has been shown to pose health risks.In this study,we first integrated 4 systems used to classify the degree of food processing and then classified FJBs into three major categories,low(minimal),moderate and high.Second,we compared the differences in attitudes towards FJBs in dietary guidelines.Third,we integrated the results of existing epidemiological surveys,randomized controlled trials,and animal experiments to explore the health risks associated with consuming FJBs.Deepening the processing of FJBs has been found to lead to an increased risk of diseases.Dietary pattern,nutrients,addition agents and consumer preferences may be influential factors.Finally,we investigated whether there were any changes in the health benefits of 100%fruit juices produced by different processing methods.In conclusion,minimally/moderately processed 100%fruit juices provide more health benefits than highly processed fruit beverages.The results support the need to consider the extent of FJBs processing in future studies to adjust official nutritional recommendations for beverage consumption.
