INTRODUCTION: Adolescent depression is prevalent, and teen suicide rates are on the rise locally. A systemic review to understand associated risk and protective factors is important to strengthen measures for the prevention and early detection of adolescent depression and suicide in Singapore. This systematic review aims to identify the factors associated with adolescent depression in Singapore. METHODS: A systematic search on the following databases was performed on 21 May 2020: PubMed, EMBASE and PsycINFO. Full texts were reviewed for eligibility, and the included studies were appraised for quality using the Newcastle Ottawa Scale. Narrative synthesis of the finalised articles was performed through thematic analysis. RESULTS: In total, eight studies were included in this review. The four factors associated with adolescent depression identified were: (1) sociodemographic factors (gender, ethnicity); (2) psychological factors, including childhood maltreatment exposure and psychological constructs (hope, optimism); (3) coexisting chronic medical conditions (asthma); and (4) lifestyle factors (sleep inadequacy, excessive internet use and pathological gaming). CONCLUSION The identified factors were largely similar to those reported in the global literature, except for sleep inadequacy along with conspicuously absent factors such as academic stress and strict parenting, which should prompt further research in these areas. Further research should focus on current and prospective interventions to improve mental health literacy, targeting sleep duration, internet use and gaming, and mitigating the risk of depression in patients with chronic disease in the primary care and community setting.

INTRODUCTION: Wheeled recreational devices (WRDs) include tricycles, bicycles, scooters, inline skates, skateboards, longboards and waveboards, and can cause significant morbidity and mortality. This study aimed to describe the epidemiology and nature of injuries sustained by children from WRD use, and risk factors for severe injury. METHOD: We described injuries relating to WRD use in children <18 years who presented to the emergency department of an Asian tertiary hospital between 2016 and 2020. Demographic data, site and nature of the injury, and historical trends were analysed. Risk factors for severe injury (defined as fractures or dislocations), Injury Severity Score ≥9, and injuries resulting in hospitalisation, surgery or death were evaluated. RESULTS: A total of 5,002 patients with 5,507 WRD-related injuries were attended to over the 5-year study period. Median age was 4.7 years. Injuries related to bicycles (54.6%) and scooters (30.3%) were most frequent, followed by skateboards and waveboards (7.4%), inline skates (4.7%), and tricycles (3.0%). Injuries occurred most frequently in public spaces. Soft tissue injuries (49.3%) and fractures (18.7%) were the most common diagnoses. Upper limb (36.4%) and head and neck (29.0%) regions were the most common sites of injury. Among the patients, 1,910 (38%) had severe injuries with potential morbidity. On multivariate analysis, heavier children of the school-going age who use either scooters, skateboards or inline skates are more prone to severe injuries. Involvement in a vehicular collision was a negative predictor. CONCLUSION WRD use in children can result in severe injuries. Wrist and elbow guards, as well as helmets are recommended, along with adequate parental supervision.

Objective: Using two measuring tools to examine the prevalence and correlates of neurocognitive impairment (NCI) as well as characteristics of neurocognitive performance among people with HIV (PWH) on antiretroviral treatment (ART). Methods: A total of 2 250 treated PWH from the Comparative HIV and Aging Research in Taizhou (CHART) were recruited in Taizhou, Zhejiang province. The Chinese version of the Mini-mental State Examination (MMSE) and the International HIV Dementia Scale (IHDS) were used to evaluate their neurocognitive performance. Cluster analysis was conducted on the seven cognitive domains in the scale. Results: Among 2 250 treated PWH, 48.0% (1 080/2 250) were aged 45 to 89, 79.2% (1 782/2 250) were male, and 37.8% (852/2 250) had primary school education or below. The prevalence of neurocognitive impairment judged by MMSE and IHDS among HIV-infected people was 14.3% (321/2 250) and 31.8% (716/2 250), respectively. Aged 60 to 89 (aOR=2.63, 95%CI:1.52-4.56), depressive symptoms (aOR=5.58, 95%CI:4.20-7.40) and treatment with EFV (aOR=2.86, 95%CI:1.89-4.34) were main risk factors of NCI diagnosed by MMSE. Male (aOR=0.71, 95%CI:0.51-1.00), overweight (aOR=0.63, 95%CI:0.44-0.89), and high education level (aOR=0.11, 95%CI:0.05-0.25) were protective factors of NCI diagnosed by MMSE. Aged 60 to 89 (aOR=3.10, 95%CI:2.09-4.59), depressive symptoms (aOR=1.78, 95%CI:1.44-2.20) and treatment with EFV (aOR=1.79, 95%CI:1.41-2.29) were risk factors of NCI diagnosed by IHDS. Male (aOR=0.75, 95%CI:0.58-0.97), underweight (aOR=0.67, 95%CI:0.47-0.96), baseline CD4⁺ T lymphocyte (CD4) counts ≥350 cells/μl (aOR=0.69, 95%CI:0.53-0.91) and high education level (aOR=0.23, 95%CI:0.14-0.39) were protective factors of NCI diagnosed by IHDS. The neurocognitive performance of HIV-infected people can be divided into four main types. Among four types, age, gender, education level, alcohol drinking, depressive symptoms, waist-to-hip ratio, hypertension, diabetes, baseline CD4 counts and treatment with EFV were different statistically (all P<0.05). Conclusions: There are four main types of neurocognitive performance in treated PWH. The prevalence of NCI is high among this population, underscoring the need for tailored prevention and intervention.

OBJECTIVE: To investigate the current situation of virus exposure risk incidents of nurses against corona virus disease 2019 (COVID-19) in Wuhan, and to provide reference evidence for nursing managers to protect nursing staff who were working in the isolation ward. METHODS: In the study, 308 nursing staff against COVID-19 working in the isolation ward in Wuhan were conveniently selected to participate in the investigation. The designed questionnaires including 7 kinds of protective exposure risk events were made by the team of researchers on the basis of literature review and interview with the nurses in Wuhan. All the participants recalled their working experience in the status of dressing in personal protective equipment and filled in the questionnaires online by WeChat according to the same instruction. RESULTS: The questionnaires were filled in validly by a total of 304 nursing staff, of whom 88.8% received emergency training on the prevention and dealing measurement of exposure risk events. The incidence of shoe cover contamination, falling off or torn was relatively high, about 53.6%. Due to the protection of gloves, the incidence of hand or skin contamination was relatively low, about 14.1%. The most nervousness of protective exposure risk event for nurses was N95 mask contamination, falling off or shifting, with a score of 8.2±2.3, showing a higher psychiatric burden. Single factor analysis found that the number of days in Wuhan was different, the number of the types of protective risk events occurred was different (χ²=14.562, P=0.024), orderly multivariate Logistic regression found that men were the independent protective factor for the number of the types of protective exposure risk events that occurred (P=0.019). CONCLUSION Protective exposure risk events may occur in the work of nursing staff working in the isolation ward in Wuhan. It is necessary to guide nurses to prevent the occurrence of protective exposure risk events and effectively deal with them, so as to prevent virus exposure and reduce psycholo-gical burden.

protective conditions in children are not well defined and represent the aims of this study.METHODS: We prospectively enrolled inpatient children submitted to antibiotic treatment. Indication, type, dose and duration of treatment, probiotic supplementation and gastrointestinal symptoms were recorded at recruitment, after two and four weeks. Antibiotic-associated diarrhea (AAD) was defined as the presence of at least 3 loose/liquid stools within 14 days from antibiotic onset.RESULTS: AAD occurred in 59/289 (20.4%) of patients, with increased risk in children younger than 3 years (relative risk [RR]=4.25), in lower respiratory (RR=2.11) and urinary infections (RR=3.67), intravenous administration (RR=1.81) and previous AAD episodes (RR=1.87). Abdominal pain occurred in 27/289 (9.3%), particularly in children >6 years (RR=4.15), with previous abdominal pain (RR=7.2) or constipation (RR=4.06). Constipation was recorded in 23/289 (8.0%), with increased risk in children having surgery (RR=2.56) or previous constipation (RR=7.38). Probiotic supplementation significantly reduced AAD (RR=0.30) and abdominal pain (RR=0.36). Lactobacillus rhamnosus GG (LGG) and L. reuteri significantly reduced AAD (RR=0.37 and 0.35) and abdominal pain (RR=0.37 and 0.24).CONCLUSION: AAD occurred in 20.4% of children, with increased risk at younger age, lower respiratory and urinary tract infections, intravenous treatment and previous AAD. LGG and L. reuteri reduced both AAD and associated abdominal pain.]]>

PURPOSE: It is controversial whether indoor pet exposure is either a risk or protective factor developing sensitization to pet allergens or asthma. Therefore, we investigated whether indoor pet ownership entails a risk for the development of asthma and sensitization in childhood. METHODS: The Panel Study of Korean Children (PSKC) is a general-population-based birth cohort study that recruited 2,078 mother-baby dyads in Korea between April and July of 2008. Among 1,577 children who were followed up in 2015, 559 underwent skin prick tests, spirometry and bronchial provocation tests using Provocholine. Having a cat or a dog and the prevalence of asthma were evaluated by using self-reported questionnaires and physicians’ medical records. RESULTS: During infancy, the rate of dog ownership was 4.5% (71 of 1,574) and that of cat ownership was 0.5% (8 of 1,574). Of the subjects, 7.9% (n=109) currently had at least 1 dog and 2.5% (n=34) had at least 1 cat. Pet ownership during infancy was associated with sensitization to cats or dogs (adjusted odds ratio [aOR], 4.24; 95% confidence interval [CI], 1.29–13.98), wheezing within 12 months (aOR, 5.56; 95% CI, 1.65–18.75) and current asthma (wheezing episode in the last 12 months+diagnosed asthma by physicians) (aOR, 6.36; 95% CI, 1.54–26.28). In contrast, pet ownership during the last 12 months was not associated with sensitization to cats or dogs or current asthma. CONCLUSION: Indoor pet exposure during infancy can be critical for developing sensitization to cats or dogs and asthma in childhood. Avoidance of pet exposure in early life may reduce sensitization to cats or dogs and development of asthma.

BACKGROUND: Dry eye disease is an aging-related ophthalmic disease that not only affects the daily activities but also causes deterioration in the quality of life. This study aimed to evaluate the factors associated with dry eye symptoms in elderly Koreans. METHODS: We investigated 4,185 subjects (men=1,787 and women=2,398) aged ≥65 years from the fifth Korea National Health and Nutrition Examination Survey 2010–2012. Data were analyzed using multiple logistic regressions to identify the relationships between dry eye symptoms and other factors. RESULTS: The prevalence of dry eye symptoms was 17.9%. After adjustment for confounding factors, dry eye symptoms were significantly associated with female sex (adjusted odds ratio [aOR], 1.806; 95% confidence interval [CI], 1.410–2.313), a history of cataract (aOR, 1.683; 95% CI, 1.255–2.255), suicidal ideation (aOR, 1.414; 95% CI, 1.070–1.870), hypercholesterolemia (aOR, 1.289; 95% CI, 1.025–1.621), age ≥80 years (aOR, 0.538; 95% CI, 0.337–0.859), and sleep duration ≥9 h/d (aOR, 0.524; 95% CI, 0.330–0.834). CONCLUSION: Among elderly Koreans, female sex, a history of cataract, suicidal ideation, and hypercholesterolemia may be the risk factors for dry eye symptoms, whereas sleep duration ≥9 h/d can be a protective factor against dry eye symptoms.

OBJECTIVES: The goals of the study are how to establish the cohort systems for the children and adolescents victims with sexual abuse in Korea and to identify the risk and protective factors that influence mental health in child sexual abuse (CSA). This is initial assessment data based on the analysis of cohort variables for baseline evaluation of subjects. METHODS: We constructed the cohort systems for CSA victims recruited by Seoul Sunflower Children Center, CSA victims protection center. The initial assessment data which consisted of demographic and psychological inventories of CSA victims and their parents/families, psychiatric diagnoses were the results of statistical analysis of 65 subjects under 19 years old for 3 years 7 months. RESULTS: The initial data were followings : female participants, N=56; mean age, 11.6 (SD=4.5); the most sexual assault, molestation 71.8%; victims, family and acquaintance 87.1%; 61.5% of the subjects diagnosed with psychiatric disorder; 29.2% diagnosed with PTSD and 23.1% diagnosed with depression. Mean duration for abuse to report is 1.5 years. Mean score of IES-R-K, TSCYC-avoidant and CBCL-problematic behavior were increased above clinical cut-off. CONCLUSIONS: CSA victims tend to have high risks in mental health problem. The cohort study could provide the risk and protective factors of CSA in mental health, and construct the predictive model for mental illness in Korea.

BACKGROUND: The correlations between the amount of daily fiber intake and bone mineral densities (BMDs) in Korean adult population were investigated in our study. METHODS: Utilizing the Korean National Health and Nutrition Examination Survey in 2011, multivariable linear regression was performed to explore the association between fiber consumption and BMD of lumbar vertebrae 1 to 4 (L1–4 total), L1, L2, L3, and L4 vertebrae, femur neck, femur total, and trochanter. All models were adjusted for age, body mass index, vitamin D level, smoking, physical activity, alcohol use, contraceptive use, hormonal replacement therapy, consumption of carbohydrate, protein, fat, calcium, phosphate, iron, thiamine, riboflavin, niacin, and vitamin C. RESULTS: In males aged between 18 and 45, fiber intake significantly increased BMDs of L1 (coefficient β=0.004, P=0.040) and L2 (β=0.004, P=0.038) while daily protein consumption significantly lowered BMDs of femur neck (β=−0.001, P=0.009), femur total (β=−0.001, P=0.008), and trochanter (β=−0.001, P=0.008). In males aged 65 and older, nutrient intake shows no significant correlations with BMDs except fat consumption was inversely associated with BMD of trochanter (β=−0.001, P=0.017). In females aged between 18 and 45, fiber intake shows no significant relationship with BMDs while daily fat consumption significantly increased BMDs of L1 (β=0.001, P=0.028), L2 (β=0.001, P=0.024), L3 (β=0.001, P=0.033), and L1–4 total (β=0.001, P=0.017). CONCLUSIONS: Fiber intake was a protective factor of lumbar spine (L1 and L2) BMD in male aged between 18 and 45 but not in female participants of any age groups.

BACKGROUND: A positive association between birth weight (BW) and body mass index (BMI) has been shown among children in many populations. The aim of this study was to investigate BMI trajectory according to BW status and the protective effect of breastfeeding on the prevalence of overweight/obesity in children 6 years of age. METHODS: A retrospective cohort study was conducted between January 1, 2008 and December 31, 2016 utilizing data from the National Health Information Database of Korea. The 38,049 subjects were followed until the end of 2016, providing that subjects were completely eligible for all health check-ups from birth to 6 years of age. At each check-up period, multiple logistic regressions were used to investigate the association between BW status (low birth weight [LBW], normal birth weight [NBW], high birth weight [HBW]) and growth development. RESULTS: HBW infants were highly likely to be overweight/obese compared to NBW infants (odds ratio [OR], 1.70–2.35) and LBW infants were highly likely to be underweight (OR, 1.69–2.20) through 6 years of age. The risk of overweight/obesity decreased significantly if HBW infants were breast-fed for 6 months (OR, 0.54–0.76). CONCLUSION: HBW status is associated with overweight/obesity during early childhood. Exclusive breastfeeding is a significant protective factor against overweight/obesity in children with HBW.
