“…The importance of engaging in an active lifestyle was found to be influential on the risk of COVID-19 over the pandemic period. The result of this study aligns with those of a recent study, which reported the decrement of PA engagement over the period of COVID-19 ( 20 ) and the lower likelihood of developing COVID-19 ( 14 ). However, the current study has taken a step forward by utilizing the most recent data available before the pandemic.…”

IntroductionDuring the coronavirus disease 2019 (COVID-19) pandemic, many populations have experienced reduced physical activity (PA) levels, weight gain, and increased anxiety and depression. However, according to a previous study, engaging in PA has a positive effect on damages caused by COVID-19. Therefore, this study aimed to investigate the association between PA and COVID-19 using the National Health Insurance Sharing Service Database in South Korea.MethodsLogistic regression analysis was used to analyze the association of PA with COVID-19 and mortality. The analysis was adjusted for body mass index, sex, age, insurance type, comorbidity, and region of residence at baseline. Disability and lifestyle (weight, smoking, and drinking status) were adjusted consecutively.ResultsThe results indicated that engaging in insufficient PA as per the WHO guidelines predicts a higher risk of COVID-19 when controlling for personal characteristics, comorbidity, lifestyle, disability, and mortality.DiscussionThis study revealed the need to engage in PA and manage weight to reduce the risk of infection and mortality associated with COVID-19. Because engaging in PA is an important component of weight management and can help restore physical and mental health after the COVID-19 pandemic, it should be emphasized as a pillar of recovery after COVID-19.

“…In urban areas, intake levels of carbohydrates, sodium, and calcium also decreased significantly during the pandemic. This reduction may be attributed to decreased physical activity resulting from social distancing measures implemented to control the spread of the virus (33), leading to a reduction in nutrient intake. However, in urban areas, the proportion of daily energy intake from protein increased significantly during the COVID-19 period compared to the pre-pandemic era.…”

BackgroundUnderstanding changes in food sufficiency within various demographic groups during emergency situations, such as the global coronavirus disease 2019 (COVID-19) pandemic, is crucial in formulating public health policies for future preparedness. This study investigated potential differences between urban and rural residents in food sufficiency trends during the COVID-19 pandemic and examined how these changes varied according to sociodemographic factors. MethodsThis cross-sectional study analyzed data from 19,724 adults aged 20 years and older, utilizing information from the 7th-8th Korea National Health and Nutrition Examination Survey (2018)(2019)(2020)(2021). ResultsIn urban areas, across all subpopulations, food sufficiency improved significantly during the COVID-19 period relative to pre-pandemic levels (p<0.001). However, in rural regions, a significant increase in food sufficiency during the COVID-19 era was observed only among women, with an odds ratio of 1.42 (confidence interval, 1.06 to 1.89). Nevertheless, no significant interaction terms were found between region and various sociodemographic factors regarding changes in food sufficiency during the COVID-19 period. ConclusionDuring the COVID-19 pandemic, food sufficiency among urban residents improved compared to the prepandemic era, whereas their rural counterparts saw no such improvement. Additionally, no significant interaction was detected between urban versus rural areas and changes in food sufficiency during the COVID-19 period.These findings indicate the need for targeted food policies to prepare for potential future pandemics, particularly in rural areas, where food sufficiency did not improve.

“…Drinking was defined as having consumed alcohol at least once a month during the past year [31]. Regular walking was defined as walking ≥30 min at least five times per week [32]. The KNHANES also recorded whether individuals brush their teeth before and after breakfast, before and after lunch, before and after dinner, after snacks, and before going to bed.…”

We investigated whether older Korean women with prolonged breastfeeding duration have an increased risk of tooth loss, chewing difficulty, or undernutrition, as well as whether tooth loss and chewing difficulty mediate the association between breastfeeding duration and undernutrition risk. This study included 1666 women aged ≥65 years from the 2013–2015 Korea National Health and Nutrition Examination Survey who breastfed after delivery. The number of teeth and chewing ability were investigated based on the status of individual teeth and a self-report questionnaire, respectively. Dietary intake was estimated using the 24 h recall method. Compared with women who breastfed for 1–18 months, the odds ratios for tooth loss were 1.16 (95% confidence interval [CI] = 0.69–1.94), 1.79 (95% CI = 1.08–2.94), and 1.86 (95% CI = 1.16–2.97) among women who breastfed for 19–36, 37–72, and ≥73 months, respectively (p for trend = 0.004). Similar results were obtained for chewing difficulty and undernutrition. Furthermore, tooth loss and chewing difficulty partially mediated the association between breastfeeding duration and undernutrition risk. In conclusion, older Korean women who breastfed for longer periods are more likely to experience tooth loss, chewing difficulty, and undernutrition, which are particularly severe among women who breastfed for ≥37 months. The association between breastfeeding duration and undernutrition risk is mediated by tooth loss and chewing difficulty.
