Factors related to femoral bowing among Korean female farmers: a cross-sectional study.

ABSTRACT: Background:Female farmers have a high prevalence of knee osteoarthritis (KOA) in South Korea. Femoral bowing has been reported to be related to KOA by increasing load on the mechanical axis. This study aimed to investigate factors related to femoral bowing in Korean female farmers. Methods:We analyzed the legs of 264 female farmers registered with the Korea farmers' knee cohort of Jeonnam Center for Farmers' Safety and Health. A structured questionnaire was used to determine sociodemographic variables, agricultural career, cumulative squatting working time (CSWT), and cumulative heavy lifting working time. Femoral bone density was measured and Kellgren-Lawrence (KL) grades were obtained from the knee radiographs. Mechanical axis angle (MAA), femoral bowing angle (FBA), anatomical lateral distal femoral angle (aLDFA), anatomical medial proximal tibial angle (aMPTA), and condylar-plateau angle (CPA) were measured. We examined the relationship between the FBA and related factors by using multiple linear regression. Results:The proportion of individuals with radiographic KOA (? KL grade 2) in this study was 37.9%. As KL grades increased, MAA, FBA, and CPA increased, whereas aLDFA and aMPTA decreased. FBA increased with age. Multiple linear regression analyses using FBA as a dependent variable showed relationship with higher age, lower height, higher BMI, lower bone mineral density, longer CSWT, and longer agricultural careers. Conclusions:The results of this study suggest that external factors related to agricultural work in female farmers was associated with femoral bowing, in addition to internal factors such as age, bone density, height, and obesity.

Project description:BackgroundInternational authorities recommend prolonged breastfeeding (PBF) for 12-24 months or more with 6 months of exclusive breastfeeding (EBF). Based on the Korean National Health and Nutrition Examination Survey (KNHANES) data, this study attempted to help encourage and educate breastfeeding (BF) over 1 year by investigating long-term BF trends and related factors in Korean infants and their mothers.MethodsThis cross-sectional study was based on data on children aged 12-23 months and their mothers from 2010 to 2020. BF rates were compared between KNHANES V (2010-2012), KNHANES VI (2013-2015), KNHANES VII (2016-2018), and part of KNHANES VIII (2019-2020). In addition, data related to mothers and infants, including demographics, socioeconomic, educational, and health status, were collected, and their association with BF status was analyzed.ResultsOf the 933 infants included in the study, the proportions achieving full BF at 6 months of age and PBF at 12 and 18 months were 34.8%, 33.7%, and 7.1%, respectively. Over the past 10 years, the trends of all three BF practices have significantly decreased since 2016 (P < 0.001). Of the 849 infants whose maternal data were available, multiple logistic regression analysis showed that EBF for 6 months (defined as full BF at 1, 3, and 6 months of age) positively correlated with maternal and infants' factors such as unemployed status, past BF experience, no history of drinking, and infants' birth weight of ≥ 2.5 kg. The mother's education level, particularly the nutrition label impact, current employment status, and smoking and drinking status, were significantly associated with PBF for ≥ 12 months but were not related to PBF for ≥ 18 months, except for drinking status.ConclusionsIn Korea, the long-term BF rate of ≥ 12 months has declined in the past 10 years, and BF becomes rare after 18 months. Higher maternal interest in nutrition information appears to be driving access to PBF over 12 months than EBF for 6 months or PBF over 18 months. To promote PBF over 12 months in Korea, it may be helpful to strengthen nutrition education that specifically emphasizes the benefits of PBF along with EBF, especially during infant health examinations.

Project description:BACKGROUND:In South Korea, the number of coronavirus disease (COVID-19) cases has declined rapidly and much sooner than in other countries. South Korea is one of the most digitalized countries in the world, and YouTube may have served as a rapid delivery mechanism for increasing public awareness of COVID-19. Thus, the platform may have helped the South Korean public fight the spread of the disease. OBJECTIVE:The aim of this study is to compare the reliability, overall quality, title-content consistency, and content coverage of Korean-language YouTube videos on COVID-19, which have been uploaded by different sources. METHODS:A total of 200 of the most viewed YouTube videos from January 1, 2020, to April 30, 2020, were screened, searching in Korean for the terms "Coronavirus," "COVID," "Corona," "Wuhan virus," and "Wuhan pneumonia." Non-Korean videos and videos that were duplicated, irrelevant, or livestreamed were excluded. Source and video metrics were collected. The videos were scored based on the following criteria: modified DISCERN index, Journal of the American Medical Association Score (JAMAS) benchmark criteria, global quality score (GQS), title-content consistency index (TCCI), and medical information and content index (MICI). RESULTS:Of the 105 total videos, 37.14% (39/105) contained misleading information; independent user-generated videos showed the highest proportion of misleading information at 68.09% (32/47), while all of the government-generated videos were useful. Government agency-generated videos achieved the highest median score of DISCERN (5.0, IQR 5.0-5.0), JAMAS (4.0, IQR 4.0-4.0), GQS (4.0, IQR 3.0-4.5), and TCCI (5.0, IQR 5.0-5.0), while independent user-generated videos achieved the lowest median score of DISCERN (2.0, IQR 1.0-3.0), JAMAS (2.0, IQR 1.5-2.0), GQS (2.0, IQR 1.5-2.0), and TCCI (3.0, IQR 3.0-4.0). However, the total MICI was not significantly different among sources. "Transmission and precautionary measures" were the most commonly covered content by government agencies, news agencies, and independent users. In contrast, the most mentioned content by news agencies was "prevalence," followed by "transmission and precautionary measures." CONCLUSIONS:Misleading videos had more likes, fewer comments, and longer running times than useful videos. Korean-language YouTube videos on COVID-19 uploaded by different sources varied significantly in terms of reliability, overall quality, and title-content consistency, but the content coverage was not significantly different. Government-generated videos had higher reliability, overall quality, and title-content consistency than independent user-generated videos.

Project description:IntroductionSexuality is a critical part of overall well-being. However, until now, studies on women's health related to the effect of sexuality on physical and psychosocial outcomes have been seriously ignored, especially the health-related quality of life (QOL) of reproductive-aged married female migrant workers.AimTo analyze the associations between sexuality-related factors and QOL and explore the independent contributions of sexuality-related factors to QOL in this population group in southern China.MethodsIn this cross-sectional survey, 609 Chinese married female migrant workers aged 19-49 years were studied. Clustered multiple linear regressions were used to analyze the associations between sexuality-related variables and QOL.OutcomesQOL was measured using the Short Form (SF-36) Healthy Survey. Details of the participants (sociodemographic, health-related and sexuality-related factors) were obtained.ResultsApproximately 10.0% of respondents always felt a lack of sexual interest and lubrication difficulties, and 37.5% of respondents seldom or never experienced sexual satisfaction. Multiple regression analyses revealed that women who never felt lubrication difficulties obtained higher role physical, bodily pain, general health, and physical component summary scores in physical domains and higher vitality (VT), mental health (MH), and mental component summary (MCS) scores in mental domains compared with those who always felt lubrication difficulties. Compared with those who always experienced sexual satisfaction, women who never experienced sexual satisfaction had relatively lower role physical, bodily pain, and general health scores in physical domains, and women who never or seldom experienced sexual satisfaction had lower VT, MH, and MCS scores in mental domains. The independent contributions of sexuality-related factors in mental domains (VT, MH, and MCS) accounted for 50.0%, 52.4%, and 39.5%, respectively; more than that of all sociodemographic and health-related variables in the VT and MH domains.ConclusionsSexuality-related factors (lubrication difficulties and sexual satisfaction) were significant independent determinants of QOL among reproductive-aged Chinese married female migrant workers, especially in mental domains.
