중년여성의 대사증후군과 폐경연령의 관계

Purpose: This study was attempted to investigate the relationship between the prevalence of metabolic syndrome and the age of menopause in middle-aged Korean women using data from The Korea National Health and Nutrition Examination Survey (Ⅸ-1, 2022). Method: The number of subjects was 1,337, and complex sample frequency, descriptive statistics, cross and logistic regression analysis were conducted using IBM SPSS Statistics 26. Results: The prevalence of metabolic syndrome in subjects who adjusted for sociodemographic and health-related characteristics simultaneously did not show a significant relationship with menopausal age. Early menopause was significantly lower by 0.30 times in high school graduates and 0.28 times lower in those with low fasting blood sugar levels, and significantly increased by 6.75 times, 4.44 times, and 2.72 times in low, middle, and non-single-person households, respectively. Late menopause was found to significantly increase 2.28 times in those with an education level of elementary school or less, 4.93 times in those with low income level, 3.85 times in those with middle income, and 2.87 times in those without binge drinking. Conclusion: Interventions that takes into account those with low levels of education or income should be prepared to prevent premature or late menopause. To manage early menopause, fasting blood sugar levels must be managed and family and social attention must be maintained for middle-aged women. To manage late menopause, personal practice of maintaining appropriate drinking habits is necessary.

Individual and community-level factors associated with repeat induced abortion among women in Ghana: a multivariable complex sample logistic regression analysis of 2017 Ghana maternal health survey

BackgroundRepeat induced abortion is a serious public health issue that has been linked to adverse maternal health outcomes. However, knowledge about repeat induced abortion and its associated factors among reproductive age women in Ghana is very scarce. The objective of this study is to examine individual and community factors associated with repeat induced abortion in Ghana which would be helpful to design appropriate programmes and policies targeted at improving the sexual and reproductive health of women.MethodsWe used secondary cross-sectional data from the 2017 Ghana Maternal Health Survey. The study included a weighted sample of 4917 women aged 15–49 years with a history of induced abortion. A multivariable complex sample logistic regression analysis was used to investigate individual and community factors associated with repeat induced abortion among women in Ghana. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) was used to measure the association of variables.ResultsOf the 4917 reproductive women with a history of abortion, 34.7% have repeat induced abortion. We find that, compared to women who experience single induced abortion, women who experience repeat abortion are age 25–34 years (AOR:2.16;95%CI = 1.66–2.79) or 35–49 years (AOR:2.95;95%CI:2.18–3.99), have Middle/JHS education (AOR:1.69;95%CI = 1.25–12.27), use contraceptive at the time of conception (AOR:1.48: 95%CI = 1.03–2.14), had sexual debut before 18 years (AOR:1.57; 95%CI: 1.33–1.85) and reside in urban areas (AOR:1.29;95%CI = 1.07–1.57). On the other hand, women who reside in Central (AOR:0.68;95%CI: 0.49–0.93), Northern (AOR:0.46;95%CI:0.24–0.88), Upper West (AOR:0.24; 95%CI: 0.12–0.50) and Upper East (AOR:0.49; 95%CI = 0.24–0.99) regions were less likely to have repeat induced abortion.ConclusionThe study showed that both individual and community level determinants were significantly associated with repeat induced abortion. Based on the findings, it is recommended to promote sexual and reproductive health education and more emphasis should be given to adult, those with early sexual debut, those with Middle/JHS education and those who live in urban centers.

Association between allergic diseases, generalized anxiety disorder, and depressive symptoms in South Korean adolescents: a secondary data analysis of the 2022 Korea Youth Risk Behavior Survey.

This study investigated the relationship between allergic diseases, general anxiety disorder, and depressive symptoms among Korean adolescents. A secondary analysis was conducted on the findings of the 18th Korea Youth Risk Behavior Survey (2022). The study included 51,850 adolescents and analyzed the relationships among allergic diseases, general anxiety disorder, and depressive symptoms using complex samples logistic regression analysis. Among the Korean adolescents, 12.7% experienced general anxiety disorder, while 28.7% experienced depressive symptoms. The prevalence of allergic diseases was 5.7% for asthma, 36.3% for allergic rhinitis, and 22.2% for atopic dermatitis. General anxiety disorder was associated with asthma and allergic rhinitis but not atopic dermatitis. Depressive symptoms were associated asthma, allergic rhinitis, and atopic dermatitis. Examining the correlation among allergic diseases, general anxiety disorder, and depressive symptoms in adolescents underscores the need for implementing suitable strategies. Moreover, when addressing general anxiety disorder and depressive symptoms in adolescents, it becomes crucial to consider the presence of allergic diseases.

우울감 노인의 정신상담 이용행태 및 영향요인 연구

Objectives This study aims to validate the influencing factors of psychological counseling utilization in elderly individuals with depression based on the Andersen Behavioral Model, which consists of predisposing factors, enabling factors, and need factors, and to provide foundational data for promoting the utilization of psychological counseling.
 Methods Using data from the 2021 Community Health Survey, we conducted complex sample cross-tabulation, univariate logistic regression analysis, and complex sample logistic regression analysis through the SPSS 20 program to identify the factors influencing the utilization of psychological counseling among 5,859 elderly individuals aged 65 and older who experienced depression.
 Results Predisposing factors included being female, younger age, higher education level, and being separated, divorced, or widowed. Enabling factors included not having unmet medical needs. Need factors included having poor subjective health status and perceiving stress, which were associated with higher utilization of psychological counseling.
 Conclusions This suggests the need for the development of strategies to promote the utilization of psychological counseling for elderly individuals with depression, with particular emphasis on prioritizing older age, lower education levels, and those with unmet medical needs.

Risk of Obstructive Sleep Apnea, Chronic Dizziness, and Sleep Duration.

Although it is recommended that obstructive sleep apnea (OSA) be screened for using a validated self-report questionnaire in patients experiencing dizziness, there is still a lack of research on the relationship between high risk of OSA and chronic dizziness. The study aimed to examine the relationship between the high risk of OSA and chronic dizziness and investigate how this relationship is affected by sleep duration. This cross-sectional study used data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). Adults aged 40 years or older were included and divided into two groups using the STOP-Bang Questionnaire (SBQ): a high-risk group for OSA or not. Complex samples logistic regression analyses were performed to examine the odds ratios of chronic dizziness based on the national population estimates. Our findings showed that individuals in the high-risk group for OSA were significantly more likely to experience chronic dizziness. Specifically, among subgroups based on sleep duration, the high-risk group for OSA with a short sleep duration of ≤5 hours demonstrated the highest odds of chronic dizziness, showing a significantly 2.48-fold increased likelihood compared to the non-high risk for OSA with a sleep duration of 5-9 hours. The SBQ can be beneficial when other causes do not explain chronic dizziness, helping to rule in the possibility of OSA. Educating individuals suspected of having OSA or who have been diagnosed with OSA about the importance of adequate sleep duration may help reduce the risk of chronic dizziness.

Examining the association of breakfast skipping with sleep disturbance, mental health, and health-related quality of life: data from the 2018 Korean community health survey

ABSTRACT Objectives: This study aimed to explore the relationship between breakfast skipping and its effects on sleep disorders, mental health, and health-related quality of life among Korean adults. Methods: Utilizing data from the 2018 Korea Community Health Survey, this cross-sectional analysis included 173,272 adults aged 19 years and older. Instruments used for assessment included the Patient Health Questionnaire-9 for depression, the EuroQol 5-dimension (EQ-5D) for health-related quality of life, and the Pittsburgh Sleep Quality Index for sleep disorders. The complex sample logistic regression analysis was employed to adjust for potential confounders. Results: Breakfast skipping was found to be significantly associated with delayed mid-sleep time, an increased propensity for daytime sleepiness, and a notable decline in sleep quality. Additionally, it was linked to a significant increase in depression risk, compromised health-related quality of life, and elevated stress levels across both genders. All five dimensions of the EQ-5D were negatively impacted by breakfast skipping. Discussion: The findings highlight the detrimental effects of skipping breakfast on sleep patterns, mental health, and overall quality of life, stressing the importance of regular breakfast consumption for enhancing these health outcomes. The study suggests the need for further research to uncover the mechanisms behind these associations and to devise targeted interventions to mitigate the negative impacts of breakfast skipping.

학업을 중단한 한국 청소년의 건강상태와 건강행위 특성

The purpose of this study is to identify the health status and health behavior characteristics of Korean adolescents who have dropped out of school in order to maintain and improve their health. Using data from the 8th National Health and Nutrition Examination Survey (2019-2021), a total of 1,097 adolescents aged 12 to 18 years old, excluding those attending elementary school and 2/3-year college or higher, are eligible in terms of education level. Among these, 53 people who responded that they did not continue their studies after graduation or dropped out were subject to discontinuation of studies. Complex sample logistic regression analysis was conducted to identify characteristics associated with dropping out of school. As a result,, adolescents who dropped out of school were more likely to have not received necessary medical services in the past year compared to adolescents who continued their education (OR: 6.77, 95% CI: 1.84-24.93, p = .004). Additionally, they were more likely to have consumed alcohol in the past year (OR: 3.02; 95% CI: 1.00-9.08, p = .050) and to engage in physical activity less than three times a week (OR: 3.77; 95% CI: 1.44- 9.89, p = .007). These research results mean that the health status and health behavior of adolescents who have dropped out of school are more vulnerable, and it is recommended that they receive necessary medical services and provide education and prevention and management programs to prevent drinking and promote physical activity. It indicates that it is required.

Factors related to scaling experience among Korean youth according to their family background: the 18th Youth Health Behavior Survey (KYRBS)

Objectives: To investigate factors related to scaling between Korean and multicultural families using data from the 18th Youth Health Behavior Survey (KYRBS), 38,320 Korean adolescents were selected as subjects. Methods: A complex sample crossanalysis was conducted on general characteristics and oral health characteristics using the IBM SPSS program. Factors related to adolescent scaling were analyzed using complex sample logistic regression analysis. Results: Compared to Korean families, adolescents from multicultural families had 0.50 times less scaling experience within 12 months. Learning achievement was 1.30 times higher in high compared to low, indicating that scaling experience was high. In terms of economic status, scaling experience was found to be high at 1.50 times in high compared to low. Non-smoking adolescents had 1.26 times higher scaling experience. It was found that adolescents who do not use dental floss and interdental brushes have 0.71 and 0.55 times less scaling experience, respectively. Conclusions: Based on the above results, there is a need to increase adolescents awareness of oral health and motivate them to manage their own oral care. There is a need to provide opportunities to participate in various oral health education programs and to deepen continuous oral health education on oral disease prevention.

Variation in maternal mortality in Sidama National Regional State, southern Ethiopia: A population based cross sectional household survey.

Maternal mortality studies conducted at national level do not provide information needed for planning and monitoring health programs at lower administrative levels. The aim of this study was to measure maternal mortality, identify risk factors and district level variations in Sidama National Regional State, southern Ethiopia. A cross sectional population-based survey was carried in households where women reported pregnancy and birth outcomes in the past five years. The study was conducted in the Sidama National Regional State, southern Ethiopia, from July 2019 to May 2020. Multi-stage cluster sampling technique was employed. The outcome variable of the study was maternal mortality. Complex sample logistic regression analysis was applied to assess variables independently associated with maternal mortality. We registered 10602 live births (LB) and 48 maternal deaths yielding the overall maternal mortality ratio (MMR) of 419; 95% CI: 260-577 per 100,000 LB. Aroresa district had the highest MMR with 1142 (95% CI: 693-1591) per 100,000 LB. Leading causes of death were haemorrhage 21 (41%) and eclampsia 10 (27%). Thirty (59%) mothers died during labour or within 24 hours after delivery, 25 (47%) died at home and 17 (38%) at health facility. Mothers who did not have formal education had higher risk of maternal death (AOR: 4.4; 95% CI: 1.7-11.0). The risk of maternal death was higher in districts with low midwife to population ratio (AOR: 2.9; 95% CI: 1.0-8.9). The high maternal mortality with district level variations in Sidama Region highlights the importance of improving obstetric care and employing targeted interventions in areas with high mortality rates. Due attention should be given to improving access to female education. Additional midwives have to be trained and deployed to improve maternal health services and consequently save the life of mothers.

Sleep duration, weekend catch-up sleep, and risk of obstructive sleep apnea in relation to handgrip strength

PurposeThis cross-sectional study aimed to evaluate whether weekday sleep duration, weekend catch-up sleep, and risk of obstructive sleep apnea are individually and in combination associated with handgrip strength. MethodsData from the Korea National Health and Nutrition Examination Survey 2019, including weekday sleep duration, weekend catch-up sleep, STOP-BANG scores, relative handgrip strength (handgrip strength divided by body mass index), and confounding factors (sociodemographic factors, health behaviors, and health and nutritional status), were evaluated in 3678 Korean adults aged 40 to 80 years. Adequate (vs. inadequate) sleep parameters were defined as weekday sleep duration (6-7 vs. ≤ 5 or ≥ 8 h), weekend catch-up sleep (presence vs. absence), and risk of obstructive sleep apnea (low vs. high based on STOP-BANG scores). Sex-specific quintiles of relative handgrip strength were categorized as high (highest 5th quintile) or low (lower 1st to 4th quintiles). A complex-sample logistic regression analysis was performed. ResultsAfter adjusting for other sleep parameters and confounding variables, each adequate sleep parameter individually and collectively was associated with high relative handgrip strength (adjusted odds ratios [95% confidence interval], 1.43 [1.09, 1.89] for 6-7 h weekday sleep duration; 1.44 [1.10, 1.90] for low risk of obstructive sleep apnea; 1.72 [1.23, 2.40] for any two parameters; 1.81 [1.18, 2.79] for all parameters). The combination of adequate weekend catch-up sleep and obstructive sleep apnea risk had the highest odds ratio for high relative handgrip strength (2.36 [1.45, 3.83]). ConclusionsAdequate weekday sleep duration, weekend catch-up sleep, and low obstructive sleep apnea risk were individually and in combination associated with high handgrip strength.

코로나19 유행으로 인한 청소년의 우울감 변화에 따른 건강행태와 정신건강

Objectives This study is intended to investigate health behavior and mental health according to depression change due to COVID-19 in adolescents and provide basic data for improving their positive health behavior and mental health.
 Methods This is a secondary analysis study that received raw data from the 17th Annual Youth Health Behavior Survey of 2021. It was analyzed through complex samples frequency analysis, complex samples cross-tabulation, and complex samples logistic regression analysis using the SPSS/WIN 20 program.
 Results First, depression change due to COVID-19 increased in girl students, high school students, high school record, low economic level, and high-educated parents. Second, adolescents with decreased depression increased in physical activity(1.13 times) and drinking(1.13 times) but decreased in smoking(0.89 times). Third, adolescents with depression change increased in smartphone use hours and damages by smartphone use. Adolescents with increased depression increased in weekday sleep time(1.64 times) and weekend sleep time(1.28 times). In particular, adolescents with increased depression increased in sadness and hopelessness(4.23 times), suicidal thoughts(5.37 times), suicide plans(4.16 times), and suicide attempts(4.98 times).
 Conclusions It is necessary to develop and apply a digital platform education program to improve the health behavior and mental health of students with depression change due to COVID-19.

Relationship between obstructive sleep apnea, insulin resistance, and metabolic syndrome: a nationwide population-based survey.

We aimed to identify the association between obstructive sleep apnea (OSA), insulin resistance (IR), and metabolic syndrome (MetS) in a nationwide population-based sample. A total of 7,900 adults with information on the STOP-Bang score and MetS (3,341 men and 4,469 women) were identified from the dataset of the Korea National Health and Nutrition Examination Survey 2019-2020. The association between OSA, IR, MetS, and its components was estimated using complex sample logistic regression analysis with adjustments for age, body mass index, residence, smoking status, alcohol consumption, household income, education, and the presence of diabetes. Participants with a high OSA score were more likely to have IR (odds ratio [OR] 2.78, 95% confidence interval [CI] 1.96-3.95 in men and OR 2.64, 95% CI 0.55-12.80 in women), MetS (OR 6.05, 95% CI 4.23-8.69 in men and OR 4.20, 95% CI 1.23-15.70 in women), and components of MetS, compared to individuals with a low OSA score. Compared to premenopausal women, postmenopausal women had a more intense association between OSA and IR (OR 1.78, 95% CI 0.13-24.43 for premenopausal women and OR 3.64, 95% CI 0.60-22.28 for postmenopausal women) and MetS (OR 2.58, 95% CI 0.23-29.55 for premenopausal women and OR 5.36, 95% CI 1.42-20.21 for postmenopausal women). OSA was associated with abdominal obesity and hypertension in premenopausal women, while all components of MetS were associated with OSA in postmenopausal women. Further studies are necessary to elucidate the underlying mechanisms of these findings.

Association between Stress Perception and Physical Activity in Elderly

Purpose: The purpose of this study was to investigate the relationship of stress perception and physical activity in the elderly over 60 years of age in Korea. Methods: This s tudy was a s econdary d ata analysis and used d ata from the 8 th 2 nd ( 2 02 0) National Health and Nutrition Examination Survey (KNHANES) as raw data. The subjects of this study were 2,360 elderly people aged 60 years or older from raw data. Data analysis was performed using IBM SPSS 25 ver. Descriptive statistics, chi-square analysis and complex sample logistic regression analysis were performed. Results: Household income, women, subjective health perception, walking were related to stress perception. In result of complex sample logistic regression analysis after adjusting the control variables, the stress perception in 60-69 ages was 2.064 times higher in the case of '1-2 days' walking per week compared to 'more than 3 days' walking per week. The stress perception in 70 years and older was 1.801 times higher in the case of 'none' walking per week compared to 'more than 3 days walking per week. Conclusion: The results provide a basis information for developing an intervention program to improve the stress management and develop a program for healthy aging.

Association between Dental Caries and Handgrip Strength: In a Population-Based Study in Korea (KNHANES 2016-2018).

This study aimed to verify the relationship between handgrip strength and oral health using data from the Korea National Health and Nutrition Examination Survey, representing Korean adults. Data from the seventh survey (2016–2018) conducted by the Korea Centers for Disease Control and Prevention were utilized, and 10,607 final study participants were recruited according to the selection and exclusion criteria. A complex sample logistic regression analysis was performed to confirm the relationship between handgrip strength and dental caries according to the sex of the study participants. On analyzing the correlation in men, “C1 (DMFT: 11–32),” when compared to “C4 (DMFT: 0–3),” in Model 1 without adjustment for potential confounders, was 2.92 (95% confidence interval [CI]: 2.15–3.97) times more likely to be associated with lower handgrip strength, and a statistically significant result was detected (p < 0.001). Additionally, significant odds ratios (ORs) were confirmed for all adjusted models. In women, the ORs in Model 1 without adjustment for potential confounders were 1.41 times (95% CI: 1.14–1.75) and demonstrated a significant result; however, the results were not significant in all adjusted models 2–4. Resultantly, a significant association was detected between dental caries and handgrip strength in Korean adults.

The Association between Physical Activity and Smartphone Addiction in Korean Adolescents: The 16th Korea Youth Risk Behavior Web-Based Survey, 2020.

Many side effects of smartphone addiction have been reported, such as a lack of sleep, obesity, and poor concentration. However, the relationship between physical activity (PA) and smartphone addiction has not been fully elucidated. This study aimed to analyze the relationship between physical activity and smartphone addiction among 53,534 Korean adolescents using raw data from the 16th (2020) Korea Youth Risk Behavior Web-based Survey (KYRBS). The dependent variables were the general user group, potential risk user group, and high-risk user group for smartphone addiction. The independent variables were moderate PA (over 5 days per week), vigorous PA (over 3 days per week), and strength exercise (over 3 days per week). Sex, body mass index (BMI), school grade, academic achievement, sleep satisfaction, depression, loneliness, and stress were selected as confounding variables. A complex sample logistic regression analysis was performed. Potential smartphone addiction risk users showed statistically significant odds ratios of 1.423 (p < 0.001), 1.379 (p < 0.001), and 1.383 (p < 0.001) based on general users participating in moderate PA, vigorous PA, and strength exercise, respectively. High-risk users showed statistically significant odds ratios of 1.475 (p < 0.001), 1.484 (p < 0.001), and 1.619 (p < 0.001), respectively. In conclusion, to prevent smartphone addiction among Korean adolescents, participation in moderate PA for more than five days a week, vigorous PA for more than three days a week, or strength exercise for more than three days a week is considered effective.

The prevalence and correlates of depression in Korean adults with rheumatoid arthritis: Results from the Korea National Health and Nutrition Examination Surveys.

This study aimed to investigate the prevalence and correlates of depression in Korean patients with rheumatoid arthritis (RA). We analyzed the data of the Korean National Health and Nutrition Examination Survey (KNHANES). The sociodemographic, clinical, and psychiatric variables were compared between the RA group (n=277) and the gender- and age-matched non-RA group (n=1068). Participants in the RA group who had a Patient Health Questionnaire-9 (PHQ-9) score of 10 or more were sub-categorized as the depression group (n=52), and the prevalence of depression with RA was determined. Complex samples logistic regression analysis was performed to clarify the associated factors for depression in patients with RA. The prevalence of depression in patients with RA was 17.4%. The RA group experienced more pain, restrictions on usual activities, and stress in their daily lives. RA patients with 3 or more comorbid diseases, extreme pain, problems in usual activities, and moderate to severe perceived stress were more likely to develop depression. Female gender and low income were also associated factors to consider. Depression is significantly prevalent in Korean RA patients. Along with managing pain and daily life functions, interventions to reduce perceived stress are needed for comprehensive RA management.

Association between Women’s Empowerment and Other Socio-Demographic and Nutritional Factors on Stunting among Children Aged 6 to 59 Months: Data from 2016 EDHS

Background: Stunting is the most prevalent form of malnutrition in children under five years of age in Ethiopia. Evidence supporting women’s impact on reducing child stunting is limited. Ithis study aimed to examine the association between women’s empowerment and socio-demographic factors on stunting among children aged 6 to 59 months. Subjects and Method: The study used the EDHS 2016 dataset. Children aged 6-59 months whose mothers (aged 15-49 years) were living with their husbands at the time of the survey were included. We enrolled 8,496 mother and child pairs. Complex sample logistic regression analysis was employed to determine the association between child stunting and the predictors. Data analyses were employed using SPSS Version 22. Results: Around 2,624 (31%) of the mothers were 25 to 29 years old. In the 12 months before the survey, around 45% (3,806) of the mothers were employed; 2,072 (54%) of them had seasonal jobs, and the 1,734 (45%) remaining mothers had full-time employment. Among employed mothers, about 50.5% (1,921) had not received payment for their work. Household wealth index (AOR= 1.9; 95% CI= 1.44 to 2.73) and maternal height (AOR= 1.9; 95% CI= 1.28 to 2.82), and having a boy child (AOR= 1.3; 95%CI= 1.08 to 1.46) is more liked associating with stunting. But maternal attitude towards wife-beating (AOR= 1.1; 95% CI= 0.89 to 1.26) had no association with it. Conclusion: children born from the poorest households, low maternal height (&lt;145cm), and male sex have increased risk of stunting. Lastly, Mothers' economic and socio-familial empowerment do not predict the risk of child stunting. Keywords: stunting, empowerment, women, Ethiopian demographic health survey.

Metabolic dysfunction associated fatty liver disease (MAFLD) and serum vitamin D concentration in South Korea.

Non-alcoholic fatty liver disease (NAFLD) has recently been renamed as metabolic dysfunction-associated fatty liver disease (MAFLD) by the Asian Pacific Association for the Study of the Liver (APASL) to reflect metabolic dysfunction. Vitamin D regulates free fatty acid flux from the periphery to the liver. The association MAFLD and vitamin D has been controversial. We investigated the association of MAFLD, nutrient intake, and vitamin D status in South Korean adults. We analyzed patient responses from the Korea National Health and Nutrition Examination survey (KNHANES) 2010-2011. The disease group was selected as per the latest guidelines. Steatosis was evaluated by the fatty liver index (FLI). Frequency analysis was performed on general characteristics. We compared differences in nutritional status using complex sample adjusted chi-square tests and generalized linear models. After adjusting for age, complex sample logistic regression analysis was used to examine the relationship between MAFLD and vitamin D. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), LDL, triglyceride, creatinine, glucose, nutrient intake, and serum 25(OH)D concentrations were significantly elevated while HDL was reduced in the disease group than in the control group. The OR for 25(OH)D was 1.015 (95% CI: 1.004-1.026, p<0.0001). However, MAFLD presented no significant association with vitamin D concentration (OR 1.010, 95% CI: 0.985-1.037, p=0.431) after adjusting for age. We found no significant relationship between MAFLD and serum vitamin D concentration in South Korean adults.

Associations between Mental Health and Oral Health among Korean Adolescents: Analysis of the National Surveys (2008-2017).

We aimed to analyze the trends and associations between the oral and mental health of Korean adolescents using the Korea Youth Risk Behavior Web-based Surveys. In total, 713,713 adolescents who participated in the surveys were included. To examine trends in oral and mental health, Pearson’s correlation coefficients were calculated between the weighted percentages and years, and the regression line slope was assessed to estimate annual changes. A complex sample logistic regression analysis was also performed. Experiencing oral symptoms and suicide-related factors both showed a gradually decreasing trend from 2008 and slight increases in 2017 and 2016, respectively. Compared with adolescents who had no oral symptoms, those with all six oral symptoms showed an increase in suicide attempts in the last 12 months, suicide ideation, and feelings of sadness and despair. In conclusion, experiencing more oral symptoms is associated with an increased risk of suicide-related factors.
