Association of sugar-sweetened beverage consumption and cardiorespiratory fitness with executive function: a cross-sectional survey based on Tajik adolescents at high altitude in China.

BACKGROUND

Executive function has a significant impact on adolescents' academic and future achievement and is strongly associated with multiple factors. However, few studies have examined the association between sugar-sweetened beverage (SSB) consumption, cardiorespiratory fitness, and executive function. Moreover, no research studies have been found on Tajik adolescents at high altitudes in China. The present study aimed to understand the associations between SSB consumption, cardiorespiratory fitness, and executive function among Tajik adolescents in high-altitude areas of China. To accumulate information on the physical and mental health development of Tajik adolescents in high-altitude areas of China.

METHODS

In this study, a cross-sectional assessment of SSB consumption, cardiorespiratory fitness, and executive function was conducted on 1,121 Tajik adolescents aged 13-15 years at high altitude in China in 2023. One-way analysis of variance (ANOVA), binary logistic regression analysis, and ordered logistic regression analysis with a generalized linear model were used to analyze the associations that existed between SSB consumption and cardiorespiratory fitness and executive function.

RESULTS

The proportions of Tajik adolescents aged 13-15 years with SSB consumption of ≤1 time/week, 2-5 times/week, and ≥ 6 times/week were 14.6, 51.6, and 33.8%, respectively, in high-altitude areas of China. The VO of Tajik adolescents was (37.17 ± 5.52) ml.kg.min. The inhibit control function response, refreshing memory function response, and switching flexibility function response of Chinese Tajik adolescents were (19.71 ± 5.86) ms, (1114.39 ± 356.85) ms, (382.2 ± 213.4) ms. Overall, using the SSB consumption ≤1 times/w and VO of the Q4 group as the reference group, ordered logistic regression analysis showed that Tajik adolescents with SSB consumption ≥5 times/w and VO of the Q1 group experienced inhibit control function dysfunction (OR = 28.80, 95%CI: 10.23 ~ 81.07), refreshing memory function dysfunction (OR = 6.79, 95%CI: 3.19 ~ 14.43), switching flexibility function dysfunction (OR = 13.10, 95%CI: 5.59 ~ 30.70) were at increased risk ( < 0.001).

CONCLUSION

SSB consumption and cardiorespiratory fitness were associated with executive function in Tajik adolescents at high altitudes in China. Increased frequency of SSB consumption and decreased cardiorespiratory fitness increased the risk of executive function disorders in Tajik adolescents. In the future, SSB consumption and cardiorespiratory fitness should be effectively controlled in Tajik adolescents to improve their executive function and promote the physical and mental health of Tajik adolescents in high-altitude areas.
