OBJECTIVES
This study investigated the potential correlation between 4 plant-based diet indices and the predicted risk of coronary heart disease (CHD) in Korean men using the Framingham Risk Score.
METHODS
The study included 12,356 male participants (aged ≥40 years) from the Health Examinees Study. Dietary intake was estimated using a validated food frequency questionnaire. Four plant-based diet indices were measured, including the overall plant-based diet index, the healthy plant-based diet index (hPDI), the unhealthy plant-based diet index (uPDI), and the pro-vegetarian diet index. Multivariable Cox proportional hazard models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for the predicted 10-year risk of CHD.
RESULTS
The study found that individuals in the highest hPDI quintile had a 19% lower risk score for CHD based on the Framingham Risk Score (model 3, HR=0.801; 95% CI, 0.689–0.930, p for trend=0.0105). In stratified analyses, the highest pro-vegetarian diet index was associated with a lower risk score for CHD in physically active individuals (HR=0.740; 95% CI, 0.588–0.931; p for interaction=0.020). Conversely, the highest uPDI was associated with the highest risk score for CHD in those with a body mass index of ≥25 kg/m² and a waist circumference ≥90 cm.
CONCLUSIONS
This prospective cohort study highlights the positive role of adhering to a high hPDI diet in the prevention of CHD in Korean men. Further prospective studies are needed to determine the association between various plant-based diet indices and the risk of CHD in Asian populations with different dietary habits.; Summary

OBJECTIVES
This study assessed the association of dietary patterns with the incidence of chronic kidney disease (CKD) and kidney function decline among Korean adults.
METHODS
Data were collected from the records of 20,147 men and 39,857 women who participated in the Health Examinees study. Principal component analysis was used to identify 3 dietary patterns (prudent, flour-based food and meat, and white rice-based), and CKD risk was defined using the Epidemiology Collaboration equation for estimated glomerular filtration rate: (eGFR) <60 mL/min/1.73 m2. A kidney function decline was defined as a >25% decrease in eGFR from baseline.
RESULTS
During the 4.2-year follow-up, 978 participants developed CKD and 971 had a 25% decline in kidney function. After adjusting for potential impact variables, compared with the lowest quartile of the prudent dietary pattern, participants in the highest quartile had a 37% lower risk of kidney function decline among men (hazard ratio [HR], 0.63; 95% confidence interval [CI], 0.47 to 0.85); while higher adherence to the flour-based food and meat dietary pattern was associated with an increased risk of CKD in both men (HR, 1.63; 95% CI, 1.22 to 2.19) and women (HR, 1.47; 95% CI, 1.05 to 2.05) as well as a decline in kidney function in both men (HR, 1.49; 95% CI, 1.07 to 2.07) and women (HR, 1.77; 95% CI, 1.33 to 2.35).
CONCLUSIONS
Although a higher adherence to the prudent dietary pattern was inversely associated with the risk of kidney function decline in men, there was no association with CKD risk. In addition, a higher adherence to the flour-based food and meat dietary pattern increased the risk of CKD and kidney function decline. Further clinical trials are needed to confirm these associations.; Summary

Korean summary
건강한 식이패턴(prudent dietary pattern)은 한국 남성의 신장기능 저하 위험을 감소와 관련성이 있었다. 반면, 밀가루 음식과 육류 위주의 식이패턴(Flour-based food and meat dietary pattern)은 남성과 여성 모두에서 신장 기능 저하 위험뿐만 아니라, 만성신장질환(CKD) 위험의 증가와 관련이 있었다. 본 연구의 결과는 한국 성인에서 식사패턴이 신장 기능 및 만성 신장 질환의 발생에 미치는 영향을 확인하였다.

Key Message
1. Better adherence to the prudent dietary pattern may lower the risk of kidney function decline in Korean man. 2. A higher adherence to the flour-based food and meat dietary pattern may higher the risk of chronic kidney disease and kidney function decline.

The association between fruit and vegetable consumption and metabolic syndrome in Korean adults: does multivitamin use matter?: Jihae Kim, Li-Juan Tan, Hyein Jung, Yumi Roh, Kyungjoon Lim, Sangah Shin; Epidemiol Health. 2022;44:e2022039.

Abstract

OBJECTIVES
Metabolic syndrome (MetS) is closely associated with dietary intake; however, few studies have investigated whether the consumption of fruits and vegetables and multivitamin use affect MetS in the Korean population. This study aimed to examine these effects in Korean adults.

METHODS

This was a cross-sectional study of 89,548 participants aged between 40 years and 69 years selected from the baseline data of the Health Examinees study conducted in Korea. Fresh vegetable and fruit consumption was assessed using a validated 106-item food frequency questionnaire. MetS and its components were defined using the National Cholesterol Education Program, Adult Treatment Panel III criteria. Multivariate logistic regression analyses were conducted to identify associations of fresh vegetable, fruit, and fresh vegetable+fruit consumption and multivitamin use with the prevalence of MetS.

RESULTS

Female in the highest quartile of fresh vegetable, fruit, and fresh vegetable + fruit consumption exhibited a lower prevalence of MetS than those in the lowest quartile. An inverse association with the prevalence of MetS was observed among male with only fresh vegetable consumption. The interaction between the 3 categories and multivitamin intake on the prevalence of MetS was not significant (all pinteraction>0.05), regardless of sex.

CONCLUSIONS

Multivitamin use and consumption of fresh vegetables and fruits had no significant synergistic effects. Although fresh vegetable and fruit consumption showed an inverse association with the prevalence of MetS, this relationship was not altered by multivitamin use.

Key Message
This study aimed to examine whether the consumption of fruits and vegetables and multivitamin use affect MetS among Korean middle-aged adults. Data was from the Health Examinees Study among 89 548 subjects. Results suggested that fruits and vegetables consumption was related with a decreased prevalence of MetS. However, there was no significant synergistic effect between the consumption of fruits and vegetables and multivitamin use in further reducing MetS prevalence.

Abstract

OBJECTIVES
It has been suggested that the consumption of dairy products helps lower the prevalence of type 2 diabetes (T2D). We investigated the association between the consumption of dairy products and T2D events in middle-aged Korean adults.

METHODS

We followed up 53,288 participants (16,895 male and 36,393 female) in the Health Examinees (HEXA) study. The consumption of dairy products was assessed using the self-administered food frequency questionnaire, and T2D was defined according to the 2015 treatment guidelines of the Korean Diabetes Association. Hazard ratios (HRs) and 95% confidence intervals (CIs) between the consumption of dairy products and the risk of T2D were calculated using Cox proportional hazards models after adjusting for potential confounders. Spline regression was used to better represent the association between the consumption of dairy products and the risk of T2D.

RESULTS

Among male, those with higher consumption of dairy products had a significantly lower risk of T2D than those who consumed essentially no dairy products (HR, 0.73; 95% CI, 0.58 to 0.91). In particular, consumption of yogurt (HR, 0.75; 95% CI, 0.60 to 0.93; ptrend=0.035) and cheese (HR, 0.66; 95% CI, 0.49 to 0.89; ptrend=0.005) was negatively associated with the incidence of T2D in male. In female, daily consumption of 1 serving of yogurt decreased the risk of T2D by 11%.

CONCLUSIONS

The association between the consumption of dairy products and the risk of T2D differed by sex and dairy product type. Further prospective studies are needed to confirm these associations.

Key Message
The study aimed to assess the association between the consumption of dairy products and type 2 diabetes events in Korean adults. Data was from the Health Examinees Study among 53 288 participants. Higher consumption of dairy products including yogurt and cheese was associated with a lower risk of developing type 2 diabetes in men. Increasing yogurt intake by one serving/day reduces the risk of type 2 diabetes in women. The association between the consumption of dairy products and the risk of type 2 diabetes differed by gender and dairy product type. Further studies are needed to confirm this.
