ABSTRACT

Purpose@#This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. @*Methods@#A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, x 2 test and logistic regression analysis were statistical tools used to analyze the data. @*Results@#In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. @*Conclusion@#Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.

ABSTRACT

Background@#Malnutrition is a well-known risk factor of falls, although studies examining the association between nutritional status and falls are rare. We aimed to investigate the association between nutritional status and falls according to gender among Korean older adults. @*Methods@#The study included 10,675 participants (4,605 men and 6,070 women) aged 65 years and older and used data from the 2011 Survey of Living Conditions and Welfare Needs of Korean Older Persons. Nutritional status of the participants was assessed using the Nutritional Screening Initiative checklist, and the participants were categorized into the following groups: “good,” “moderate nutritional risk,” and “high nutritional risk.” Odds ratios (OR) of fall risk in the above groups based on gender were evaluated using multivariate logistic regression analyses. @*Results@#Fallers in both genders showed significant association with older age, lower household income, inadequate exercise, and poor nutritional status compared with non-fallers. Considering the good nutritional status group as the reference group, the high nutritional risk group showed a higher risk of falls in men (OR, 1.59; 95% confidence interval [CI], 1.26–1.99); both moderate and high nutritional risk groups showed a higher risk of falls after adjusting for confounding factors in women (OR, 1.39; 95% CI, 1.19–1.62 and OR, 1.90; 95% CI, 1.61–2.24, respectively). @*Conclusion@#The risk of falls was associated with poor nutritional status, and statistical significance of the association between nutritional status and falls was stronger in women than in men.

ABSTRACT

Background@#Recent studies suggest that acanthosis nigricans (AN) is associated with insulin resistance in obese children. However, very few studies have assessed insulin resistance and obesity according to the degree of AN. Therefore, this study aimed to investigate the correlation between the degree of obesity and insulin resistance according to the severity of AN. @*Methods@#A total of 141 participants (83 boys and 58 girls) aged 6−17 years were recruited for the Intervention for Childhood and Adolescents obesity via Activity and Nutrition study between 2016 and 2017. The participants were categorized into four groups according to the severity of AN: grade 0 (n=69), grade 1 (n=19), grade 2–3 (n=35), and grade 4 (n=18). All participants underwent physical examination and blood tests. We compared the mean homeostatic model assessment (HOMA-IR) and body mass index Z score (BMI Z-score) in each group using ANCOVA and linear regression model. @*Results@#The HOMA-IR, which represents insulin resistance, increased with increasing AN severity (grade 0 group: 3.25±0.070; grade 1 group: 3.97±0.103; grade 2–3 group: 4.76±0.079; AN grade 4: 6.40±0.107; P for trend<0.001). Similarly, the BMI Z-score, which represents the degree of obesity, increased with increasing AN severity (grade 0 group: 2.29±0.052; grade 1 group: 2.42±0.080; grade 2–3 group: 2.44±0.062, grade 4: 2.67±0.089; P for trend<0.001). @*Conclusion@#Insulin resistance and the degree of obesity increase with the severity of AN in Korean obese children.
