Objectives
This study aimed to analyze the association between sugar intake and cancer risk among Korean adults aged 19 years and older.
Methods
A total of 13,016 adults aged 19 years and older who participated in the 8th Korea National Health and Nutrition Examination Survey from 2019 to 2021 were included. Sugar intake was assessed in terms of both absolute intake and sugar energy rate. Sugar intake was divided into quartiles, while sugar energy rate was categorized into three groups (< 10%, 10%–20%, > 20%) based on the 2020 Dietary Reference Intakes for Koreans and into two groups (< 10%, ≥ 10%) based on WHO recommendations. Cancer prevalence was determined using cancer-related survey questions. The association between sugar intake and cancer prevalence was analyzed by sex and cancer type using logistic regression. All statistical analyses were performed using IBM SPSS statistics 29.0 (IBM Co.).
Results
From 2019 to 2021, sugar intake significantly declined with age in both men and women (P for trend < 0.001), with the highest intake observed in the 19–29 age group (61.38 g). Men consumed significantly more sugar than women across all age groups except for the 50–64 and 65–74 groups (P < 0.05). However, the sugar energy rate was significantly higher in women than in men (P < 0.05). While the association between sugar intake and cancer prevalence varied across regression models and cancer types, cervical cancer consistently showed a significant association with sugar intake (P < 0.05).
Conclusion
The association between sugar energy rate and the prevalence of premenopausal cervical cancer was consistent and significant. Given that women had a higher sugar energy rate than men, the relationship between sugar intake and cancer prevalence in women warrants further investigation. Longitudinal studies with more detailed sugar intake assessments are needed.

Total sugar intake and its contributed foods by age groups in Koreans using the 8th (2019–2021) Korea National Health and Nutrition Examination Survey: a cross-sectional study: Hyejin Yu, Sang-Jin Chung; Korean J Community Nutr 2024;29(3):222-233.

Abstract PDF PubReader ePub: Objectives
This study was conducted to investigate the status of total sugar intake and contributing foods in Korea according to age groups.
Methods
This study used 24-hour dietary recall data from the 8th Korea National Health and Nutrition Examination Survey (2019–2021) to investigate the nutritional and total sugar intake status among Koreans. A total of 18,338 research participants (≥3 years old) were included in this study. To analyze the types of foods contributing to total sugar intake, these foods were categorized into 15 types. Moreover, we examined the total sugar intake and ranked the most consumed foods by age groups (3–11 years, 12–18 years, 19–34 years, 35–49 years, 50–64 years, over 65 years). A survey procedure was employed for statistical analysis.
Results
The energy intake ratio from total sugars was approximately 12%–15%, which was within the recommended range. However, the proportion of individuals consuming total sugar exceeding 20% of their total caloric intake is nearly 20%, raising concerns about excessive sugar consumption. Furthermore, the percentage of participants whose intake of sugar from processed foods exceeded 10% of their total calories was highest in the 12–18 age group at 37.1%, followed by the 3–11 age group at 35.2%, and the 19–34 age group at 34.0%. Carbonated drinks, cola, and cider were the primary foods consumed by children and adolescents (3–18 years old) and young adults (19–34 years old). For middle-aged and older adults, mixed coffee with sugar and cream was a prominent contributor to sugar intake.
Conclusions
This study investigated sugar consumption patterns among Koreans, finding the principal foods contributing to this intake. Identifying these contributors is pivotal, given their potential impact on public health.
