Social Determinants of Health of Multicultural Adolescents in South Korea: An Integrated Literature Review (2018~2020)

Purpose@#This study is an integrated literature review to analyze health problems and social determinants of multicultural adolescents in South Korea. @*Methods@#An integrative review was conducted according to Whittemore & Knafl’s guideline. An electronic search that included publications from 2018 to 2020 in the PubMed, EMBASE, Cochrane Library, CINAHL, RISS, and KISS databases was conducted. Of a total of 67 records that were identified, 13 finally met full inclusion criteria. Text network analysis was also conducted to identify keywords network trends using NetMiner program. @*Results@#The health problems of multicultural adolescents were classified into mental health (depression, anxiety, suicide and acculturative stress) and health risk behaviors (smoking, risky drinking, smartphone dependence and sexual behavior). As social determinants affecting the health of multicultural adolescents, the biological factors such as gender, age, and visible minority, and the psychological factors such as acculturative stress, self-esteem, family support, and ego-resiliency were identified. The sociocultural factors were identified as family economic status, residential area, parental education level, and parents' country of birth. As a result of text network analysis, a total of 41 words were identified. @*Conclusion@#Based on these results, mental health and health risk behaviors should be considered as interventions for health promotion of multicultural adolescents. Our findings suggest that further research should be conducted to broaden the scope of health determinants to account for the effects of the physical environment and health care system.

Association of Work-Time, Leisure-Time Physical Activity and Osteoporosis Prevalence: Korea National Health and Nutrition Examination Survey in 2015–2016

BACKGROUND: Physical activity is an important factor for preventing osteoporosis. This study aimed to investigate the association of work- and leisure-time physical activities with osteoporosis in postmenopausal women.METHODS: Data were obtained from the Korea National Health and Nutritional Examination Survey 2015–2016. A total of 2,885 postmenopausal women were included in the analysis. The subjects were divided into 3 groups according to the intensity of the work- and leisure-time physical activities. T-test, chi-square test, and multivariable logistic regression analysis were used.RESULTS: No association was found between work-time physical activity and osteoporosis prevalence. However, a dose-response relationship was found in case of leisure-time physical activity. People with leisure-time physical activity of at least >1,000 MET-min/week showed lower prevalence of osteoporosis.CONCLUSION: An appropriate level of leisure-time physical activity should be recommended to prevent and treat osteoporosis.

The Effects of Diet Alone or in Combination with Exercise in Patients with Prehypertension and Hypertension: a Randomized Controlled Trial

BACKGROUND AND OBJECTIVES@#Supervised lifestyle interventions, including dietary and exercise programs, may be infeasible to implement in real-world settings. Therefore, this study aimed to evaluate the effectiveness of a home-based lifestyle modification intervention on blood pressure (BP) management.@*METHODS@#Eighty-five patients aged over 20 years and diagnosed with prehypertension or mild hypertension were randomly assigned to an advice-only comparison group (C group, n=28), a Dietary Approaches to Stop Hypertension (DASH) diet education group (D group, n=30), or a DASH and home-based exercise group (D+Ex group, n=27). The intervention lasted for 8 weeks. The primary outcome was the difference in office systolic blood pressure (SBP) before and after the study period (Trial registry at ClinicalTrials.gov, NCT01637909).@*RESULTS@#Seventy-two participants (87.8%) completed the trial. The degree of change in office SBP did not significantly differ among the intervention groups; however, the D+Ex group demonstrated a tendency toward decreased SBP. Upon analysis of 24-hour ambulatory BP measurements, daytime ambulatory SBP was significantly lower in the D+Ex group (134 mmHg; 95% confidence interval [CI], 131 to 137; p=0.011) than in the C group (139.5 mmHg; 95% CI, 130.9 to 137), and daytime ambulatory SBP was significantly decreased in the D+Ex group (−5.2 mmHg; 95% CI, −8.3 to −2.1; p=0.011) compared to the C group (0.4 mmHg, 95% CI, −2.5 to 3.3).@*CONCLUSIONS@#In conclusion, lifestyle modification emphasizing both diet and exercise was effective for lowering BP and should be favored over diet-only modifications.

Attributional Style in Healthy Persons: Its Association with 'Theory of Mind' Skills

OBJECTIVE: Attributional style, especially external personal attribution bias, was found to play a pivotal role in clinical and non-clinical paranoia. The study of the relationship of the tendency to infer/perceive hostility and blame with theory of mind skills has significant theoretical importance as it may provide additional information on how persons process social situations. The aim of this study was whether hostility perception bias and blame bias might be associated with theory of mind skills, neurocognition and emotional factors in healthy persons. METHODS: Total 263 participants (133 male and 130 female) were recruited. The attributional style was measured by using the Ambiguous Intentions Hostility Questionnaire (AIHQ). Participants were requested to complete a Brune's Theory of Mind Picture Stories task, neurocognitive task including Standard Progressive Matrices (SPM) and digit span, and other emotional dysregulation trait scales including Rosenberg's self-esteem, Spielberg's trait anxiety inventory, and Novaco anger scale. RESULTS: Multiple regression analysis showed that hostility perception bias score in ambiguous situation were found to be associated with theory of mind questionnaire score and emotional dysregulation traits of Novaco anger scale. Also, composite blame bias score in ambiguous situation were found to be associated with emotional dysregulation traits of Novaco anger scale and Spielberg's trait anxiety scale. CONCLUSION: The main finding was that the attributional style of hostility perception bias might be primarily contributed by theory of mind skills rather than neurocognitive function such as attention and working memory, and reasoning ability. The interpretations and implications would be discussed in details.

The Cardiovascular Effects of Thoracic Bolus Epidural Injection of Lidocaine, Morphine and Fentanyl during Sevoflurane General Anesthesia / 대한마취과학회지

BACKGROUND: Sevoflurane is an inhalational anesthetic that produces rapid induction, emergence and little cardiovascular depression. Elevated sympathetic activity during surgery produces undesirable effects on the cardiovascular system, such as hypertension, tachycardia or arrhythmias. So combined general and epidural anesthesia have been used recently for the operation, especially the abdominal surgery. This study was performed to evaluate the cardiovascular effects of thoracic epidural anesthesia during sevoflurane general anesthesia. METHODS: Forty patients of ASA class 1-2 undergoing elective subtotal gastrectomy were divided into 5 groups. Thoracic epidural bolus injection was administered via an epidural catheter during sevoflurane general anesthesia in a double-blind random manner: Group 1; normal saline (N/S) 10 ml (placebo), Group 2; morphine 0.1 mg/kg mixed with N/S in 10 ml, Group 3; fentanyl 1 mcg/kg mixed with N/S in 10 ml, Group 4; 1% lidocaine 10 ml, and Group 5; 1% lidocaine 10 ml mixed with morphine 0.1 mg/kg and fentanyl 1 mcg/kg. Systolic and diastolic blood pressures, pulse rates, peripheral oxygen saturation levels (SpO2) and end-tidal carbon dioxide partial pressures (ETCO2) were measured every 5 minutes. RESULTS: Systolic and diastolic blood pressures were significantly reduced from 10 minutes after epidural bolus injection in groups 4 and 5, but these decreases in blood pressure were not severe enough to require treatment in either group. Pulse rates were significantly decreased from 10 minutes after injection in groups 3, 4, and 5, but these decreases in pulse rate were not so severe enough to require treatment in 3 groups. SpO2 and ETCO2 were stable, and arrhythmia was not observed. CONCLUSIONS: The thoracic epidural injection of 1% lidocaine mixed with morphine 0.1 mg/kg and fentanyl 1 mcg/kg can be safely used during sevoflurane anesthesia without severe cardiovascular complications during upper abdominal surgery in ASA 1-2 patients.
