Background
Interest in healthy aging has grown with the increase in the older population. Nutritional intake is crucial in frailty. Therefore, we aimed to investigate the relationship between frailty and multivitamin and mineral supplements (MVMS), which can easily provide micronutrients.
Methods
The Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2018 to 2019 included 3,395 adults aged ≥65 years. Of these, 1,511 who did not consume dietary supplements (DS, non-DS group) and 415 who took MVMS (MVMS group) were included in the study. We modified Fried’s definition of frailty to fit the KNHANES data. Using multivariate logistic regression, we examined the association between MVMS use and frailty, which varied with satisfaction with total energy intake. Additional subgroup analyses were performed based on age, sex, and income.
Results
MVMS reduced most micronutrient deficiencies compared to obtaining nutrients solely through food. The overall analysis revealed no association between MVMS use and frailty (odds ratio [OR], 0.75; 95% confidence interval [CI], 0.52–1.09). However, a subanalysis revealed that participants with a low income (≤25%) who took MVMS had decreased odds for frailty (OR, 0.55; 95% CI, 0.35–0.88) compared with the non-DS group. Furthermore, a significant association between using MVMS and frailty was confirmed in the group with low income and energy intake below the recommended daily allowance, with a low OR of 0.52 (95% CI, 0.30–0.90).
Conclusion
MVMS use was significantly associated with frailty among the low-income and low-daily energy intake groups.

Background
Cancer survivors experience decreased physical function and reduced muscle strength, which leads to lower quality of life (QOL). The hand grip strength (HGS) can be a predictor of poor health-related QOL as a parameter of sarcopenia. The purpose of this study was to investigate the relationship between low HGS and QOL in cancer survivors and healthy controls.
Methods
We analyzed 392 cancer survivors and 1,176 healthy controls from the Korea National Health and Nutrition Examination Survey, 2014–2017. We defined low HGS as 2 standard deviation values for healthy young Korean adults from a previous study. QOL was evaluated using the European Quality of Life Scale-Five Dimensions. A complex sample logistic regression model was used to assess the relationship between each dimension of low HGS and QOL.
Results
The odds ratios (ORs) for decreased QOL were significantly higher in male cancer survivors with low HGS on self-care (OR, 8.51; 95% confidence interval [CI], 1.69–42.83) and usual activities (OR, 6.63; 95% CI, 1.22–36.03). The ORs for problems in mobility (OR, 5.87; 95% CI, 2.04–16.91), usual activities (OR, 14.46; 95% CI, 3.84–54.44), pain/discomfort (OR, 4.90; 95% CI, 2.00–12.01), and anxiety/depression (OR, 6.43; 95% CI, 2.16–19.12) were significantly high in female cancer survivors with low HGS. However, healthy controls showed no significant relationship between low HGS and QOL.
Conclusion
For cancer survivors, low HGS was associated with poor QOL in some domains. Strategies to increase muscle strength must be considered to improve the QOL of cancer survivors.

Background
In 2015, tobacco prices significantly increased in Korea as part of the government’s smoking cessation policy. This study examined the changes in the stages of smoking cessation among Korean male smokers before and after the implementation of the tobacco price policy, and identified the predictors of such changes.
Methods
The study population comprised 3,533 male current smokers (age ≥19 years) who participated in the Korea National Health and Nutrition Survey in 2012, 2013, 2015, and 2016. Current smokers were defined as persons who had smoked ≥100 cigarettes during their lifetime and are continuing to smoke. In accordance with the transtheoretical model, smokers were classified into the precontemplation stage (no plan to quit), contemplation stage, and preparation stage (planning to quit within 6 months). We examined the changes in the smoking cessation stages before and after the implementation of the policy. Multivariate logistic regression analysis was conducted to identify factors related to the likelihood of continuing smoking, after adjustments for potential confounders.
Results
Immediately after the policy implementation, the percentage of smokers in the precontemplation stage decreased from 65.6% to 60.8% (P=0.014). However, this effect was temporary. Significant risk factors for remaining in the precontemplation stage were older age (odds ratio [OR], 1.010; 95% confidence interval [CI], 1.002–1.018; P=0.004), being in the lowest income quartile (OR, 1.226; 95% CI, 1.001–1.502; P=0.049), and manual worker or unemployed status (OR, 1.256; 95% CI, 1.036–1523; P=0.020).
Conclusion
Increasing tobacco prices only temporarily change the stage of smoking cessation among Korean male smokers.
