XRCC1 Arg399Gln and clinical outcome of platinum-based treatment for advanced non-small cell lung cancer: a meta-analysis in 17 studies

Objective: XRCC1 polymorphism is a research hotpot in individual treatment for non-small cell lung cancer (NSCLC). To obtain the association between XRCC1 polymorphism and clinical outcome of platinum-based treatment for NSCLC, a meta-analysis was conducted. Methods: Databases including PubMed, Embase, Cochrane, and Chinese National Knowledge Infrastructure (CNKI) were searched for publications that met the inclusion criteria. A fixed effect model was used to estimate pooled odds ratio (OR) and hazard ratio (HR) with 95% confidence interval (CI) for the association between XRCC1 Arg399Gln and response or survival of platinum-based treatment for advanced NSCLC. A chi-squared-based Q-test was used to test the heterogeneity hypothesis. Egger’s test was used to check publication bias. Results: Seventeen published case-control studies that focus on the association between XRCC1 Arg399Gln and response or survival of platinum-based treatment for advanced NSCLC in 2 256 subjects were included in this meta-analysis, of whom 522 were AA genotypes (23.2% frequency), 916 AG genotypes (40.6% frequency), and 818 GG genotypes (36.2% frequency). The overall response rate (ORR) was 45.2% (110/243) for AA genotype patients, 29.9% for AG genotype (73/244), and 30.7% for GG genotype (124/403). The heterogeneity test did not show any heterogeneity and the Egger’s test did not reveal an obvious publication bias among the included studies. The meta-analysis indicated that AA genotype patients presented higher response rates toward platinum drug treatment compared with G model (GG+GA) patients (GG vs. AA model: OR=0.489, 95% CI 0.266–0.900, P=0.021; AG vs. AA model: OR=0.608, 95% CI 0.392–0.941, P=0.026; GA+AA vs. GG model: OR=1.259, 95% CI 0.931–1.701, P=0.135; GG+GA vs. AA model: OR=0.455, 95% CI 0.313–0.663, P=0.0001). However, no evidence validates XRCC1 associates with the survival following platinum drug therapy. Conclusions: Our meta-analysis suggested that XRCC1 Arg399Gln is related with the sensitivity of NSCLC patients to platinum-based treatment. AA genotype patients present more desirable curative effectiveness compared with other patients.     

Association of CASP9, CASP10 gene polymorphisms and tea drinking with colorectal cancer risk in the Han Chinese population

The initiators caspase-9(CASP9) and caspase-10(CASP10) are two key controllers of apoptosis and play important roles in carcinogenesis.This study aims to explore the association between CASPs gene polymorphisms and colorectal cancer(CRC) susceptibility in a population-based study.A two-stage designed population-based case-control study was carried out,including a testing set with 300 cases and 296 controls and a validation set with 206 cases and 845 controls.A total of eight tag selected single nucleotide polymorphisms(SNPs) in CASP9 and CASP10 were chosen based on HapMap and the National Center of Biotechnology Information(NCBI) datasets and genotyped by restriction fragment length polymorphism(RFLP) assay.Multivariate logistic regression models were applied to evaluate the association of SNPs with CRC risk.In the first stage,from eight tag SNPs,three polymorphisms rs4646077(odds ratio(OR) AA+AG:0.654,95% confidence interval(CI):0.406-1.055;P=0.082),rs4233532(OR CC:1.667,95% CI:0.967-2.876;OR CT:1.435,95% CI:0.998-2.063;P=0.077),and rs2881930(OR CC:0.263,95% CI:0.095-0.728,P=0.036) showed possible association with CRC risk.However,none of the three SNPs,rs4646077(OR AA+AG:1.233,95% CI:0.903-1.683),rs4233532(OR CC:0.892,95% CI:0.640-1.243;OR CT:1.134,95% CI:0.897-1.433),and rs2881930(OR CC:1.096,95% CI:0.620-1.938;OR CT:1.009,95% CI:0.801-1.271),remained significant with CRC risk in the validation set,even after stratification for different tumor locations(colon or rectum).In addition,never tea drinking was associated with a significantly increased risk of CRC in testing set together with validation set(OR:1.755,95% CI:1.319-2.334).Our results found that polymorphisms of CASP9 and CASP10 genes may not contribute to CRC risk in Chinese population and thereby the large-scale case-control studies might be in consideration.In addition,tea drinking was a protective factor for CRC.     

Association between serum vitamin D and severity of liver fibrosis in chronic hepatitis C patients: a systematic meta-analysis

To conduct a systematic review of group studies assessing the association of serum vitamin D status with the severity of liver fibrosis in chronic hepatitis C patients using meta-analysis. The relevant research literatures were identified by searching PubMed and EMBASE databases prior to October 2013 with no restrictions. We included group studies that reported odds ratio (OR) estimates with 95% confidence intervals (CIs) or a mean with standard deviation (SD) for the association between serum vitamin D status and the severity of liver fibrosis in chronic hepatitis C patients. Approximately 8321 participants from several countries were included in this analysis. Six studies on serum vitamin D status and the severity of liver fibrosis were included in this meta-analysis. ORs with 95% CIs were extracted from four studies and the pooled ORs were 0.866 (95% CI, 0.649 to 1.157). The means with SDs were extracted from three studies and the pooled means were −0.487 (95% CI, −0.659 to −0.315). There was statistically significant heterogeneity among the mean data extracted studies (P=0.029; I ²=71.8%) but not among the OR data extracted studies (P=0.061; I ²=55.6%). Finally, results from the mean data extracted studies suggest that lower serum vitamin D is a risk factor for the severity of liver fibrosis in chronic hepatitis C patients. However, there is no conclusive evidence on this association because of inconsistencies between the OR data extracted studies and the mean data extracted studies.     

Efficacy of amiodarone and lidocaine for preventing ventricular fibrillation after aortic cross-clamp release in open heart surgery: a meta-analysis of randomized controlled trials

Objective

The relative preventative efficacy of amiodarone and lidocaine for ventricular fibrillation (VF) after release of an aortic cross-clamp (ACC) during open heart surgery has not been determined. This meta-analysis was designed to systematically evaluate the influence of amiodarone, lidocaine, or placebo on the incidence of VF after ACC.

Methods

Prospective randomized controlled trials (RCTs) that compared the VF-preventative effects of amiodarone with lidocaine, or amiodarone or lidocaine with placebo were included. PubMed, EMBASE, and the Cochrane Library were searched for relevant RCTs. Fixed or randomized effect models were applied according to the heterogeneity of the data from the selected studies.

Results

We included eight RCTs in the analysis. Pooled results suggested that the preventative effects of amiodarone and lidocaine were comparable (relative risk (RR)=1.12, 95% confidence interval (CI): 0.70 to 1.80, P=0.63), but both were superior to the placebo (amiodarone, RR=0.71, 95% CI: 0.51 to 1.00, P=0.05; lidocaine, RR=0.63, 95% CI: 0.46 to 0.88, P=0.006). The percentage of patients requiring electric defibrillation counter shocks (DCSs) did not differ significantly among patients administered amiodarone (RR=0.21, 95% CI: 0.04 to 1.19, P=0.08), lidocaine (RR=2.44, 95% CI: 0.13 to 44.02, P=0.55), or the placebo (RR=0.56, 95% CI: 0.25 to 1.25, P=0.16).

Conclusions

Amiodarone and lidocaine are comparably effective in preventing VF after ACC, but the percentage of patients who subsequently require DCSs does not differ among those administered amiodarone, lidocaine, or placebo.

     

Behavioral problems among children whose mothers are abused by an intimate partner

OBJECTIVES: To determine the association between children's exposure to maternal intimate partner violence (IPV) and behavior problems as measured by the parent report version of the Child Behavior Checklist (CBCL). METHODS: The study population was comprised of 167 2- to 17-year-old children of Seattle women with police-reported or court-reported intimate partner abuse. The CBCL normative population served as the comparison group. Risk of behavior problems was calculated among the exposed children, in the presence and absence of a history of reported child maltreatment, relative to the normative population. Multiple logistic regression served as the primary method of analysis. RESULTS: Children exposed to maternal IPV were more likely to have borderline to clinical level scores on externalizing (i.e., aggressive, delinquent) behavior (RR=1.6, 95% CI: 1.2, 2.1) and total behavioral problems (RR=1.4, 95% CI: 1.1, 1.9) compared to the CBCL normative sample after adjusting for age and sex. Children who were exposed to maternal IPV and were victims of child maltreatment were more likely to receive borderline to clinical level scores on internalizing (i.e., anxious, depressed) behaviors (RR=2.6, 95% CI: 1.5, 3.6), externalizing (i.e., aggressive, delinquent) behaviors (RR=3.0, 95% CI: 1.9, 4.0) and total behavioral problems (RR=2.1, 95% CI: 1.2, 3.2) compared to the CBCL normative sample after adjusting for age and sex. CONCLUSIONS: Exposure to maternal IPV is significantly associated with child behavioral problems both in the presence and absence of co-occurring child maltreatment. Appropriate attention to the mental health of children living in households with IPV is needed.     

A meta-analysis of randomized trials on clinical outcomes of paclitaxel-eluting stents versus bare-metal stents in ST-segment elevation myocardial infarction patients

A meta-analysis was performed to address the efficacy and safety of paclitaxel-eluting stent (PES) in ST-segment elevation myocardial infarction (STEMI) patients. A systematic literature search was conducted to identify all randomized clinical trials in mortality, recurrent myocardial infarction (rMI), repeat revascularization (RR), and stent thrombosis (ST). A total of 4190 STEMI patients were enrolled in six randomized trials comparing PES with bare-metal stent (BMS). The pooled repeat revascularization rate was 5.7% in PES group, significantly lower than 10.0% in BMS group with an odds ratio (OR) of 0.56, 95% confidence interval (CI) [0.44, 0.72] (P<0.00001). No significant difference was found between PES and BMS groups in mortality at one year after the indexing procedure (3.9% vs. 5.1%, OR 0.88, 95% CI [0.63, 1.21], P=0.42). Similarly, rMI rate did not differ significantly between the two groups (3.4% vs. 4.1%, OR 0.80, 95% CI [0.56, 1.13], P=0.21). PES was also associated with the comparable pooled rate of definite stent thrombosis with BMS (2.3% vs. 2.4%, OR 0.81, 95% CI [0.52, 1.26], P=0.35). The results show that PES improved clinical outcomes in STEMI patients with a decreased need for repeat revascularization and no concerns for safety.

Association of matrix metalloproteinase-9 C1562T polymorphism and coronary artery disease: a meta-analysis简

Objective

Many investigations have studied the associations between matrix metalloproteinase-9 (MMP-9) C1562T polymorphisms and coronary artery disease (CAD). However, the conclusions of these studies were inconsistent. Therefore, this study was aimed at clarifying the association between MMP-9 C1562T polymorphisms and CAD in a large-scale meta-analysis.

Methods

The PubMed and Embase databases were retrieved to collect all publications on the association between MMP-9 C1562T polymorphisms and CAD. Then the odd ratios (ORs) and 95% confidence intervals (95% CIs) for C1562T TT+TC versus CC genotype between CAD and the control groups were evaluated. Subgroup analysis was also performed according to different races. The meta-analysis was performed by Stata 10.0.

Results

Sixteen case-control studies were included in our meta-analysis, involving 11 032 CAD patients and 4628 non-CAD controls. Compared with C allele carriers, East Asian T allele carriers TT+TC had a significantly higher risk of CAD (OR=1.43; 95% CI: 1.03–1.99; P=0.031); however, there were no significant associations in Western populations (OR=1.06; 95% CI: 0.96–1.18; P=0.240) or West Asians (OR=1.13; 95% CI: 0.75–1.70; P=0.565). When further analyzing the association between C1562T polymorphisms and myocardial infarction (MI, the most serious type of CAD), the risk of TT+TC genotype versus CC genotype for MI was significantly higher for the overall (OR=1.21; 95% CI: 1.04–1.40; P=0.012) and for East Asians (OR=1.58; 95% CI: 1.26–1.97; P=0.000) but not in Western populations (OR=1.12; 95% CI: 0.99–1.26; P=0.078).

Conclusions

Our meta-analysis suggested an obvious ethnic difference in the association between MMP-9 C1562T polymorphisms and CAD. MMP-9 C1562T polymorphism was significantly related to CAD in East Asians. However, no significant associations were observed in either West Asians or Western populations.     

Effects of antiepileptic drugs on bone mineral density and bone metabolism in children: a meta-analysis

Objective: The aim of our meta-analysis was to assess the effects of antiepileptic drugs on bone mineral density and bone metabolism in epileptic children. Methods: Searches of PubMed and Web of Science were undertaken to identify studies evaluating the association between antiepileptic drugs and bone mineral density and bone metabolism. Results: A total of 22 studies with 1492 subjects were included in our research. We identified: (1) a reduction in bone mineral density at lumbar spine (standardized mean difference (SMD)=−0.30, 95% confidence interval (CI) [−0.61, −0.05]), trochanter (mean difference (MD)=−0.07, 95% CI [−0.10, −0.05]), femoral neck (MD=−0.05, 95% CI [−0.09, −0.02]), and total body bone mineral density (MD=−0.33, 95% CI [−0.51, −0.15]); (2) a reduction in 25-hydroxyvitamin D (MD=−3.37, 95% CI [−5.94, −0.80]) and an increase in serum alkaline phosphatase (SMD=0.71, 95% CI [0.38, 1.05]); (3) no significant changes in serum parathyroid hormone, calcium, or phosphorus. Conclusions: Our meta-analysis suggests that treatment with antiepileptic drugs may be associated with decreased bone mineral density in epileptic children.     

Effect of corticosteroids on atrial fibrillation after catheter ablation: a meta-analysis

Objective

The purpose of this meta-analysis was to explore the effect of corticosteroids on atrial fibrillation (AF) following catheter ablation.

Methods

We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials for published articles describing the effect of corticosteroids in preventing AF recurrence after catheter ablation. Data on study and patient were extracted. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated by use of a random-effect model, and P values of <0.05 were considered significant.

Results

Two randomized controlled trials (RCTs) and three cohort studies involving 846 patients were included in this meta-analysis. Within one month of catheter ablation, corticosteroid use was associated with a declined risk of recurrence of AF in RCT (RR 0.57, 95% CI 0.39 to 0.85, P=0.005), but without significant effect in cohort studies (RR 1.01, 95% CI 0.79 to 1.30, P=0.94). After three months of catheter ablation, corticosteroids did not have a significant effect in the prevention of late recurrence of AF in either RCT (RR 0.78, 95% CI 0.38 to 1.59, P=0.49) or cohort studies (RR 0.96, 95% CI 0.70 to 1.31, P=0.78).

Conclusions

Our meta-analysis suggested that periprocedural administration of corticosteroids of catheter ablation was associated with reduction of early but not late recurrence of AF.

     

Levosimendan versus dobutamine in critically ill patients: a meta-analysis of randomized controlled trials

Objective

To evaluate the clinical efficacy of levosimendan versus dobutamine in critically ill patients requiring inotropic support.

Methods

Clinical trials were searched in PubMed, EMBASE, and the Cochrane Central Registry of Clinical Trials, as well as Web of Science. Studies were included if they compared levosimendan with dobutamine in critically ill patients requiring inotropic support, and provided at least one outcome of interest. Outcomes of interest included mortality, incidence of hypotension, supraventricular arrhythmias, and ventricular arrhythmias.

Results

Data from a total of 3 052 patients from 22 randomized controlled trials (RCTs) were included in the analysis. Overall analysis showed that the use of levosimendan was associated with a significant reduction in mortality (269 of 1 373 [19.6%] in the levosimendan group, versus 328 of 1 278 [25.7%] in the dobutamine group, risk ratio (RR)=0.81, 95% confidence interval (CI) 0.70-0.92, P for effect=0.002). Subgroup analysis indicated that the benefit from levosimendan could be found in the subpopulations of cardiac surgery, ischemic heart failure, and concomitant β-blocker therapy in comparison with dobutamine. There was no significant difference in the incidence of hypotension, supraventricular arrhythmias, or ventricular arrhythmias between the two drugs.

Conclusions

In contrast with dobutamine, levosimendan is associated with a significant improvement in mortality in critically ill patients requiring inotropic support. Patients having cardiac surgery, with ischemic heart failure, and receiving concomitant β-blocker therapy may benefit from levosimendan. More RCTs are required to address the questions about no positive outcomes in the subpopulation in a cardiology setting, and to confirm the advantages in long-term prognosis.     

Serum lipids and other risk factors for diabetic retinopathy in Chinese type 2 diabetic patients

Objective

To investigate the association of serum lipids and other risk factors with diabetic retinopathy (DR) in Chinese type 2 diabetic patients.

Methods

Five hundred and twenty-three type 2 diabetic patients underwent ophthalmic examination by experienced retinal specialists to assess their DR. Serum lipids, including triglycerides, total cholesterol, high density lipoprotein cholesterol (HDLC), and low density lipoprotein cholesterol (LDLC), were measured using Roche automated clinical chemistry analyzers. The concentration of very low density lipoprotein cholesterol (VLDLC) was calculated based on total cholesterol, HDLC and LDLC. Hyperlipidemia was defined as a total cholesterol concentration of 6.2 mmol/L or higher or the use of lipid-lowering medications. The association of risk factors with any DR or proliferative diabetic retinopathy (PDR) was assessed using the odds ratio (OR) and its 95% confidence interval (CI), calculated from logistic regression models.

Results

In multivariate logistic regression models, hyperlipidemia (OR=2.39, 95% CI: 1.02–5.66), higher VLDLC (OR=1.59, 95% CI: 1.14–2.23), and higher triglyceride (OR=1.18, 95% CI: 1.03–1.37) were associated with increased risk of DR. A longer diabetic duration was associated with increased risk of DR (P<0.0001) and PDR (P=0.002) in a dose-response manner. Higher systolic blood pressure (P=0.02) and higher serum creatinine (P=0.01) were independently associated with increased risk of DR, and female gender was associated with increased risk of PDR (P=0.03).

Conclusions

Among Chinese type 2 diabetic patients, hyperlipidemia, higher VLDLC, and higher triglyceride were independently associated with increased risk of DR, suggesting control of serum lipids may decrease the risk of DR.     

Association of p53 codon 72 polymorphism with liver metastases of colorectal cancers positive for p53 overexpression

Objective: To evaluate the association between p53 codon 72 polymorphism (R72P) and the risk of colorectal liver metastases. Methods: The p53 R72P genotype was identified by polymerase chain reaction-restriction fi'agment length poly-morphism (PCR-RFLP) method in 78 consecutive colorectal cancer patients with liver metastases and 214 age- and sex-matched cases with nonmetastatic colorectai cancer. Results: The R allele of the p53 R72P polymorphism was more frequently found in metastatic cases than in nonmetastatic cases (P=0.075). Carriers of the 72R allele had a 2.25-fold (95% CI (confidence inter-val)=1.05～4.83) increased risk of liver metastases. On the stratification analysis, 72R-carrying genotype conferred a 3.46-fold (95% CI=1.02～11.72) and a 1.05-fold (95% CI=0.36～3.08) increased risk of liver metastases for p53 overexpression-positive and negative colorectal cancers, respectively. Conclusion: These results demonstrate for the first time that the 72R allele of the p53 polymorphism has an increased risk for liver metastases in colorectal cancers positive for p53 overexpression.     

HER-2 overexpression and survival in colorectal cancer: a meta-analysis

Objective

Numerous studies examining the relationship between human epidermal growth factor receptor 2 (HER-2) overexpression and survival in patients with colorectal cancer (CRC) have yielded controversial results. We therefore performed a meta-analysis more precisely to estimate its prognostic value.

Methods

Published studies investigating the effect of HER-2 overexpression on CRC survival were identified; the hazard ratios (HRs) and their corresponding 95% confidence intervals (95% CIs) were pooled in terms of disease-specific or overall survival.

Results

Eleven studies were included in the meta-analysis. The pooled data showed that HER-2 overexpression was negatively related to CRC survival (HR=1.10, 95% CI: 0.77–1.44). Subgroup analyses regarding test method and study quality also demonstrated little association between HER-2 overexpression and CRC survival (HR=0.89, 95% CI: 0.50–1.29; HR=0.90, 95% CI: 0.43–1.37, respectively).

Conclusions

Regardless of several limitations, our study suggested that HER-2 overexpression probably had little impact on CRC survival.     

Spanking and subsequent behavioral problems in toddlers: A propensity score-matched,prospective study in Japan

Harsh or frequent spanking in early childhood is an established risk factor for later childhood behavioral problems as well as mental disorder in adulthood in Western societies. However, few studies have been conducted in Asian populations, where corporal punishment is relatively accepted. Moreover, the impacts of occasional spanking on subsequent behavioral problems remain uncertain. This study sought to investigate prospectively the association between the frequency of spanking of toddlers and later behavioral problems in Japanese children using national birth cohort data. We used data from the Longitudinal Survey of Newborns in the 21st Century, a population-based birth cohort data set collected by the Japanese Ministry of Health, Labour, and Welfare (N = 29,182). Frequency of spanking (“never”, “sometimes” and “always”) and child behavioral problems were assessed via a caregiver questionnaire when the child was 3.5 years old and again at 5.5 years. Propensity score matching was used to examine the association between frequency of spanking and child behavioral problems, adjusting for parental socioeconomic status, child temperament and parenting behaviors. Compared to children who were never spanked, occasional spanking (“sometimes”) showed a higher number of behavioral problems (on a 6-point scale) (coefficient: 0.11, 95% CI: 0.07–0.15), and frequent spanking (“always”) showed an even larger number of behavioral problems compared with “sometimes” (coefficient: 0.08, 95% CI:0.01–0.16). Spanking of any self-reported frequency was associated with an increased risk for later behavioral problems in children.     

Eight-year outcome of implementation of abusive head trauma prevention

Low incidence rates and economic recession have hampered interpretation of educational prevention efforts to reduce abusive head trauma (AHT). Our objective was to determine whether the British Columbia experience implementing a province-wide prevention program reduced AHT hospitalization rates. A 3-dose primary, universal education program (the Period of PURPLE Crying) was implemented through maternal and public health units and assessed by retrospective-prospective surveillance. With parents of all newborn infants born between January 2009 and December 2016 (n = 354,477), nurses discussed crying and shaking while delivering a booklet and DVD during maternity admission (dose 1). Public health nurses reinforced Talking Points by telephone and/or home visits post-discharge (dose 2) and community education was instituted annually (dose 3). During admission, program delivery occurred for 90% of mothers. Fathers were present 74.4% of the time. By 2–4 months, 70.9% of mothers and 50.5% of fathers watched the DVD and/or read the booklet. AHT admissions decreased for <12-month-olds from 10.6 (95% CI: 8.3–13.5) to 7.1 (95% CI: 4.8–10.5) or, for <24-month-olds, from 6.7 (95% CI: 5.4–8.3) to 4.4 (95% CI: 3.1–6.2) cases per 100,000 person-years. Relative risk of admission was 0.67 (95% CI: 0.42–1.07, P = 0.090) and 0.65 (95% CI: 0.43-0.99, P = 0.048) respectively. We conclude that the intervention was associated with a 35% reduction in infant AHT admissions that was significant for <24-month-olds. The results are encouraging that, despite a low initial incidence and economic recession, reductions in AHT may be achievable with a system-wide implementation of a comprehensive parental education prevention program.     

Childhood maltreatment: A predictor of mental health problems among adolescents and young adults

Child maltreatment is a risk factor for detrimental effects on mental health that may extend to adulthood. This study aimed to examine the association between exposure to childhood maltreatment, socio-demographic factors, and students’ mental health status and self-esteem. A cross-sectional study enrolled a representative sample of 1270 students from Kuwait University. An anonymous self-administered questionnaire included students’ socio-demographic characteristics, history of exposure to childhood physical and/or emotional maltreatment, DASS-21 to assess mental health status, and Rosenberg self-esteem scale was used. Chi-square test and binary logistic regression models were applied. The study found that among participants, 49.6%(95% CI: 64.8%–52.4%), 63.0%(95% CI: 60.3%–65.7%), and 43.8%(95% CI: 41.1%–46.6%) reported having depression, anxiety, and stress respectively. Moreover, 22.5%(95% CI: 20.1%–24.8%) and 18.6%(95% CI:16.5%–20.9%) reported childhood physical and emotional maltreatment, respectively; while 12.7% reported both. Multivariate analysis revealed that experiencing childhood physical and emotional maltreatment were independent contributors to reporting depression and anxiety; while exposure to only emotional maltreatment contributed to reporting stress. Gender, GPA, childhood enrollment in private/public schools, number of close friends, were other contributors to mental health problems. Participants’ median score of self-esteem was 17/30, and only childhood emotional maltreatment was a significant predictor to low self-esteem after adjustment for other confounders. Mental health problems, and experiencing childhood physical and emotional maltreatment were prevalent relatively high among university students. Childhood corporal and emotional maltreatment were independent predictors to adolescents and young adults’ mental health problems. Experiencing childhood emotional maltreatment predicted low self-esteem. Further research to assess culture factors associated with childhood maltreatment is recommended.     

Prevalence and correlates of physical abuse in Hong Kong Chinese adolescents: a population-based approach.

OBJECTIVE: The objectives were to estimate the prevalence and correlates of physical abuse-related outcomes in the family setting in Hong Kong's adolescent population. METHOD: A cross-sectional study design was used. A randomly selected sample of 3,355 secondary school students in Kwai Tsing District of Hong Kong was surveyed. The response rate was 98%. RESULTS: The prevalence rates of corporal punishment, being beaten by parents for no apparent reason, being beaten to injury by family members in the past 3 months and any one of the above three were 4.9% (95% CI, 4.2% to 5.6%), 2.0% (95% CI, 1.5% to 2.5%), 1.1% (95% CI, .98% to 1.2%) and 6.6% (95% CI, 5.7% to 7.5%), respectively. Students who had experienced the above physical abuse-related outcomes were at a significant disadvantage for a wide range of morbidity indicators, including self-perceived bad health, anxiety and stress, somatic illnesses (such as asthma and epigastric pain), injuries and accidents, and hospitalization. They were more likely to have poor familial relations and coping skills, and to take up habits which potentially put their health at risk, such as smoking, alcohol consumption, and fighting with others. CONCLUSIONS: Our prevalence estimates of physical abuse in the family setting for a student population in Hong Kong is an improvement over previous local estimates of physical abuse occurrence, which were mainly based on case notifications and clinical samples. The results also show that the abused adolescents are growing up in an environment filled with physical, psychological, and familial adversities.
