Child maltreatment and telomere length in middle and older age: retrospective cohort study of 141 748 UK Biobank participants.

BACKGROUND: There is evidence that child maltreatment is associated with shorter telomere length in early life. AIMS: This study aims to examine if child maltreatment is associated with telomere length in middle- and older-age adults. METHOD: This was a retrospective cohort study of 141 748 UK Biobank participants aged 37-73 years at recruitment. Leukocyte telomere length was measured with quantitative polymerase chain reaction, and log-transformed and scaled to have unit standard deviation. Child maltreatment was recalled by participants. Linear regression was used to analyse the association. RESULTS: After adjusting for sociodemographic characteristics, participants with three or more types of maltreatment presented with the shortest telomere lengths (ß = -0.05, 95% CI -0.07 to -0.03; P < 0.0001), followed by those with two types of maltreatment (ß = -0.02, 95% CI -0.04 to 0.00; P = 0.02), referent to those who had none. When adjusted for depression and post-traumatic stress disorder, the telomere lengths of participants with three or more types of maltreatment were still shorter (ß = -0.04, 95% CI -0.07 to -0.02; P = 0.0008). The telomere lengths of those with one type of maltreatment were not significantly different from those who had none. When mutually adjusted, physical abuse (ß = -0.05, 95% CI -0.07 to -0.03; P < 0.0001) and sexual abuse (ß = -0.02, 95% CI -0.04 to 0.00; P = 0.02) were independently associated with shorter telomere length. CONCLUSIONS: Our findings showed that child maltreatment is associated with shorter telomere length in middle- and older-aged adults, independent of sociodemographic and mental health factors.

Who Is at High Risk for Child Abuse and Neglect: Risk Assessment among Battered Women Using Shelter Services.

BACKGROUND: The intersections between intimate partner violence (IPV) and child abuse and neglect (CAN) have received growing attention from the research community. However, there is limited research examining the risk factors for CAN among children of battered women who have experienced severe IPV and seek refuge in shelters. OBJECTIVE: In the current study, we examined the co-occurrence of IPV and CAN and the risk factors for CAN in a sample of battered women. PARTICIPANTS AND SETTING: We recruited 260 battered women who were staying in women's shelters in Hong Kong. METHODS: We analyzed the data collected from the risk assessment reports of battered women and focused on IPV against women, CAN, and risk assessment. RESULTS: Nearly half of the battered women had reported both IPV against themselves and CAN against their children. These women were, in general, younger, unemployed, and had been living in Hong Kong for less than seven years as new immigrants. Other risk factors for CAN in violent families included women's conflicts with their partner and abusers with higher levels of stress and approval of violence. CONCLUSIONS: This exploratory study of risk factors for the co-occurrence of IPV and CAN advances our understanding of the causes of violence against women and children in families with violence. Our findings suggest that additional integrated services should be offered to both battered women and their children during their stay in shelters and after shelter departure. Addressing IPV and CAN and reducing adverse consequences needs greater collaboration among the various stakeholders across the social services, health, educational, and legal sectors.

Social, Community, and Cultural Factors Associated with Parental Stress in Fathers and Mothers.

Parenting stress is a key factor in predicting the quality of parent−child relationships and child development outcomes. Previous research tends to focus on examining individual factors contributing to parental stress, with minimal attention to other important contextual factors that may affect parenting. This study examines the issue from a broader ecological perspective by investigating social, cultural, and community factors associated with parental stress in a community sample of economically active fathers and mothers in Hong Kong. A secondary analysis was conducted using the data from the 2017 Family Survey, a territory-wide household survey conducted in Hong Kong. The data of the current study included a sub-sample of 736 working-class parents (48.4% males and 51.6% females). The mean age of fathers and mothers was 50.99 (SD = 11.2) and 48.68 (SD = 10.34) years, respectively. Mothers reported significantly higher levels of parental stress than fathers, t = −4.241, p < 0.001. Different social, cultural, and community factors were associated with parental stress for fathers and mothers. Strong endorsement of traditional family values (B = −0.23, p = 0.032) and frequent practice of filial piety (B = −0.005, p = 0.019) reduced parental stress in fathers. Additionally, fathers who perceived formal support as effective scored higher levels of parental stress, B = 0.20, p < 0.001. For mothers, informal social support from family members was the only social predictor for reduced parental stress (B = −0.14, p < 0.001) among all the other contextual variables. Community support to reduce parental stress in working parents should address the respective risk factors for fathers and mothers.

The association between victimization and inflammation: A meta-analysis.

BACKGROUND: To meta-analyze the existing studies examining the association of childhood and adulthood victimization with inflammation and to explore the moderating variables that affect these relationships. METHODS: Relevant work published before 28th February 2021 was identified by searching five major databases. We analyzed the cross-sectional data extracted from cross-sectional and longitudinal studies using the random-effects model to estimate the correlation (r) as the pooled effect size and further conducted subgroup analyses and sensitivity analyses. RESULTS: A total of 37 articles finally met the inclusion criteria, including studies for C-reactive protein (CRP) (k = 23; NCRP = 11,780), interleukin-6 (IL-6) (k = 31; NIL-6 = 8943), and tumor necrosis factor-alpha (TNF-α) (k = 14; NTNF-α = 4125). Overall, victimization has a significantly positive association with inflammation, with a small effect size (r = 0.122). Specifically, effect sizes were the largest for TNF-a (r = 0.152), followed by IL-6 (r = 0.119), and CRP (r = 0.084). Additionally, the effect sizes for victimization against children were r = 0.145 (k = 6) for childhood victimization - childhood inflammation, and r = 0.139 (k = 27) for childhood victimization - adulthood inflammation, which appear to be larger than that of victimization against adults (r = 0.039; k = 2). LIMITATIONS: Only a small number of studies on adult victimization were included. In addition, we only analyzed the cross-sectional relationship and did not have sufficient data to compare different types of victimization and single vs. multiple victimizations. CONCLUSIONS: Victimization is associated with a heightened inflammatory response. As victimization against children may have a stronger effect than victimization against adults, prevention of victimization targeting the childhood period may be necessary. Studies with more robust methodologies (i.e., representative, longitudinal, and multi-country designs) are needed to confirm these findings and to unpack the underlying mechanisms.

Changing Patterns of Intimate Partner Violence against Pregnant Women: A Three-Year Longitudinal Study.

Intimate partner violence (IPV) against pregnant women adversely impacts women's and infants' health. This study aims to provide longitudinal evidence regarding how pregnant women's exposure to IPV changes over time. Additionally, we examine the risk and protective factors associated with these changes. In total, 340 pregnant women were recruited from an antenatal clinic in Hong Kong. IPV experiences and health conditions were assessed at pregnancy and at both 4 weeks and 3 years after childbirth. The women also reported adverse childhood experiences (ACEs), their family support, and perceived partner involvement. We found IPV prevalence among the study sample decreased from 22.9% before pregnancy to 13.5% during pregnancy, 14.7% at 4 weeks after childbirth, and 11.8% at 3 years after childbirth. We further found three types of IPV: 11.8% of women had a violent relationship (VR) persistently over time from pregnancy to 3 years after childbirth, 20.6% experienced decreased IPV (DVR), and 67.6% reported a nonviolent relationship (NVR) throughout the study period. VRs were associated with more severe mental health problems and higher ACEs. Family support and partner involvement may be protective factors for decreased IPV. Our present findings highlight the importance of identifying different IPV types over time to provide targeted intervention to the most vulnerable groups.

Association between Childhood Exposure to Family Violence and Telomere Length: A Meta-Analysis.

The aims of this meta-analysis were to examine the association between childhood exposure to family violence and telomere length and the moderating variables that influence this association. Relevant works published on or before 1st September 2022 were identified through a search in five major databases in English and 19 articles (N = 18,977) finally met the inclusion criteria. A meta-analysis was conducted to compute the pooled effect size (correlation; r), and moderator analyses were performed using a random effects meta-analytic model. The studies yielded a significant inverse association between childhood exposure to family violence and telomere length, with a small effect size (r = -0.038, 95% CI [-0.070, -0.005], p = 0.025). Furthermore, the strength of this association was stronger in studies examining the co-occurrence of multiple types of violence than in those examining just one type (Q = 8.143, p = 0.004). These findings suggested that victims' telomere length may be negatively influenced by childhood exposure to family violence and that such impairment appears to be stronger for those who are exposed to multiple types of violence. Future studies are necessary to examine the moderating and mediating factors underlying the association between childhood exposure to family violence and telomere length.

The effectiveness of parenting programs in regard to improving parental reflective functioning: a meta-analysis.

Although parenting interventions aiming to improve parental RF have been developed, there have been conflicting results in regard to intervention effectiveness. This meta-analytic review seeks to synthesize the available evidence that group-based parenting interventions improve parental RF, in order to provide conclusive evidence regarding their effectiveness. A systematic search was performed to retrieve relevant studies published before November 2019. A total of 15 studies met the selection criteria, of which 3 studies were randomized controlled trials (RCTs). The studies yielded a significant intervention effect with a small pooled effect size (Hedge's g = 0.279, p = 0.002) on parental RF. However, the pooled effect size of the 3 RCTs was non-significant (pooled effect size: Hedge's g = 0.189, p = 0.244), indicating that current best evidence is limited. As the heterogeneity test was significant (Q = 32.486, df = 14, p = 0.003), which suggests the presence of heterogeneity among the selected studies, a series of moderator analyses were performed to examine factors that may influence intervention effects. Interventions that involved children in middle childhood had a larger effect size than those involving children in infancy and early childhood.

Influence of Maternal Infection and Pregnancy Complications on Cord Blood Telomere Length.

BACKGROUND: Exposure to suboptimal intrauterine environment might induce structural and functional changes that can affect neonatal health. Telomere length as an important indicator of cellular health has been associated with increased risk for disease development. OBJECTIVES: This study was aimed to examine the independent and combined effects of maternal, obstetric, and foetal factors on cord blood telomere length (TL). METHODS: Pregnant women at the gestational age of 20th to 24th week who attended the antenatal clinic of a major local hospital in Hong Kong were recruited. Participants were asked to complete a questionnaire on demographics, health-related quality of life, and history of risk behaviors. Medical history including pregnancy complications and neonatal outcomes was obtained from electronic medical records of both mother and neonate. Umbilical cord blood was collected at delivery for TL determination. RESULTS: A total of 753 pregnant women (average age: 32.18 ± 4.51 years) were recruited. The prevalence of maternal infection, anaemia, and hypertension during pregnancy was 30.8%, 30.0%, and 6.0%, respectively. The adjusted regression model displayed that maternal infection was negatively associated with cord blood TL (ß = -0.18, p = 0.026). This association became even stronger in the presence of antenatal anaemia, hypertension, delivery complications, or neonatal jaundice (ß = -0.25 to -0.45). CONCLUSIONS: This study consolidates evidence on the impact of adverse intrauterine environment at the cellular level. Maternal infection was significantly associated with shorter cord blood TL in a unique manner such that its presence may critically determine the susceptibility of telomere to other factors.

Association of harsh parenting and maltreatment with internet addiction, and the mediating role of bullying and social support.

Growing evidence has shown that exposure to harsh parenting and child maltreatment elevate the risk of Internet addiction in adolescence. Yet, limited research has examined the mechanisms underlying this association. The present study was a cross-sectional school survey of 1204 adolescents (52.2 % male and 47.8 % female; mean age, 13.36 years) in Hong Kong. The adolescents completed a self-reported questionnaire about their exposure to bullying victimization, bullying perpetration, child maltreatment, Internet addiction, and social support. The findings showed that harsh parenting and maltreatment was significantly associated with Internet addiction. After controlling for a number of confounding factors, the results of the mediation analyses showed that family support and bullying perpetration, and family support and bullying victimization accounted for 36 % and 25 % of the effect of harsh discipline and maltreatment on Internet addiction, respectively. Effective prevention and intervention strategies for Internet addiction should target family and social vulnerabilities in adolescents.

Risk of Child Maltreatment in Chinese Teenage and Young Mothers With Rapid Repeat Pregnancy: The Moderating Role of Family Cohesion and Support From Friends.

Rapid repeat pregnancy (RRP) often occurs in teenage and young mothers. Mothers with a history of RRP are more likely to experience high stress increasing their risk of child maltreatment. Despite these challenges, some mothers can continue to cope adaptively. Social support may play a role in empowering these mothers to overcome the childbearing difficulties. Although the protective effects of social support are well recognized, there has been little evidence on the relative importance of sources of support. For example, whether support from family and friends is equally important in relieving parenting stress remains unanswered. RRP, a social phenomenon encompassing various adverse living and parenting issues, provides an ideal research context to investigate the role of family and friends in preventing child maltreatment. This study examined whether family cohesion and friends' support moderated the association between RRP and child maltreatment in young mothers. We recruited 392 Chinese teenage and young mothers from a population-based integrated young mothers supporting program in Hong Kong. Questionnaires on pregnancy history, family cohesion, social support, and risk of child maltreatment were administered. Moderation analysis was conducted to examine the effect of RRP on child maltreatment as a function of family cohesion or friend support. Results showed that RRP was associated with a higher risk of child neglect (adjusted odds ratio [aOR] = 1.72, p < .05) and physical maltreatment (aOR = 1.91, p < .01), and that family cohesion was more important than friend support in mitigating the risk of child maltreatment for mothers with a history of RRP. Our findings suggest that interventions for young mothers, particularly those with a history of RRP, should be family-based so the whole family can be empowered to tackle the childrearing burden.

Disentangling the Effects of Exposure to Maternal Substance Misuse and Physical Abuse and Neglect on Child Behavioral Problems.

There is inconsistent evidence on the association between prenatal substance exposure and child behavioral problems. Children affected by maternal substance misuse are vulnerable to physical abuse and neglect. Few studies have examined factors contributing to internalizing and externalizing problems in these children. This study, with a focus on children with prenatal substance exposure, investigated whether family characteristics (the duration of maternal substance misuse postpartum or the existence of a sibling) moderated the association between adverse exposure (physical abuse or neglect) and behavior (internalizing or externalizing problems). We recruited 54 Hong Kong Chinese mothers with registered records of substance misuse during pregnancy and their children (2-9 years). Mothers completed questionnaires on drug use patterns during pregnancy and postpartum, abusive and neglectful parenting behaviors in the preceding year, and children's current behavioral problems. Moderated regression analyses tested whether abusive and neglectful parenting behavior interacted with family characteristics to affect child behavioral problems. The existence of a sibling moderated the relationship between neglect experience and internalizing problems, with a positive relationship observed only among single children (adjusted B [95% confidence interval] = 3.70 [0.98, 6.41], p = .012). The duration of maternal substance misuse postpartum moderated the relationship between physical abuse experience and externalizing problems, with a positive relationship observed only among children of mothers abusing substances beyond the child's infancy period (adjusted B [95% confidence interval] = 6.86 [2.34, 11.38], p = .008). The results show that the impact of physical abuse and neglect experiences depend on the type of behavior assessed and family and child characteristics. Positive sibling relationship and early detoxification in the mother can foster healthy behavioral development for children exposed prenatally to maternal substance misuse.

The association between intimate partner violence against women and newborn telomere length.

Intimate partner violence (IPV) against women negatively impacts infant health. However, its impact on infant's biology, in particular on telomere length (TL) is unknown. The aim of this study was to examine the association between IPV against women before childbirth and cord blood TL in their newborn. A total of 774 pregnant women in the 20th-24th week of gestation were recruited at a public hospital in Hong Kong. The mothers' exposure to IPV before childbirth, demographic characteristics, obstetric outcomes, health and mental health were measured at the time of recruitment and 4 weeks after childbirth. Umbilical cord blood was collected by midwives at the time of delivery. The newborn TL was quantified using quantitative PCR method and expressed in T/S ratio (the ratio of telomere repeat copy numbers to single-copy gene numbers). After adjusting for a number of confounding variables, the mothers' exposure to any IPV before childbirth (ß = -0.08, 95% CI = -0.14, -0.01) was associated with shorter TL. Specifically, psychological abuse against women before childbirth (ß = -0.08, 95% CI = -0.15, -0.02) and sexual abuse against women before childbirth (ß = -0.22, 95% CI = -0.43 to -0.01) were significantly associated with reduced newborn TL. This study is the first to provide evidence of an association between IPV against women before childbirth and TL shortening in their newborns. Through TL- dependent transcription and epigenetic mechanisms, our finding suggests maternal exposure to IPV may exert a life-long impact on the offspring's health.

Screening for Multiple Types of Family Violence: Development and Validation of the Family Polyvictimization Screen.

Objective: Different types of violence tend to co-occur within a family where the members often share common family characteristics, a situation described as family polyvictimization. In response to the lack of a validated screening tool, this study developed and validated the Family Polyvictimization Screen (FPS), the first brief screening tool applicable to members of the same family with up to three generations. Methods: The FPS was designed to screen family polyvictimization by assessing and capturing different types of violence, including child abuse and neglect (CAN), intimate partner violence (IPV), and elder abuse. The FPS was compared with the Criterion Standard scales. It is suitable for use as a self-report for individual family members for specific violence or as a proxy report for an adult family member to serve as informant. In this study, a community sample of 445 households was recruited from Hong Kong (n = 250) and Shanghai (n = 195). One adult parent from each three-generation family was selected as the informant to report all family polyvictimization experiences in the preceding year. Results: Moderate to high agreement (79.1-99.8%) was found between the FPS and the standard measurements, such as the revised Conflict Tactics Scales (CTS2) and the Conflict Tactics Scales: Parent-Child Version (CTSPC). Exceptions appeared in regard to physical assault on elders due to the rarity of reported cases. The specificity was high, while the sensitivity estimates appeared low, especially for the more sensitive sexual abuse cases. Conclusion: The validated FPS demonstrated its potential utility as a brief tool for screening family polyvictimization in clinical settings with substantial agreement and satisfactory accuracy in the Chinese population.

Prevalence of Child Maltreatment and Its Association with Parenting Style: A Population Study in Hong Kong.

Previous studies point to a link between parenting style and child maltreatment, but evidence from a Chinese context is lacking. We investigated the association between parenting style and child maltreatment in Hong Kong, and examined whether family socio-economic status and child gender moderate this relationship. Using stratified random sampling, 7585 children in Grade 1 to Grade 3 of 51 schools in Hong Kong were recruited and their parents were invited to complete the questionnaire. The past year weighted prevalence for minor physical abuse, severe/very severe physical abuse, psychological abuse, and neglect were 63.9%, 23.4%, 84.1%, and 23.2%, respectively. Authoritarian parenting was associated with all types of child maltreatment (prevalence ratio (PR) range: 1.10⁻1.53; p < 0.001), whereas authoritative parenting was associated with a lower risk of all types of child maltreatment (PR range: 0.89⁻0.97; p < 0.001). Child maltreatment is prevalent in Hong Kong and is strongly associated with parenting style. The association was significantly stronger among girls and those with higher family socioeconomic status. Education to empower parenting skills may alleviate the burden of child maltreatment.

Disability-Specific Associations with Child Health and Functioning.

This study examined the health profile of children with different types of disabilities and explored the disability-specific associations with various types of health and functioning using a large nonclinical sample of children. A cross-sectional school survey was conducted during 2016 and 2017. A total of 4114 children (aged 6⁻18 years) receiving primary or secondary education, or their proxy, in Hong Kong participated in the study. Disabilities were categorized as (a) physical disabilities; (b) learning and developmental disabilities; (c) intellectual disabilities; (d) internalizing disorders or mental illness; and (e) autism spectrum disorder. Health-related quality of life (QoL), sleep-related QoL, activities of daily living (ADL), emotional functioning, and social functioning were assessed and compared between children with disabilities and those without. The results showed that children with disabilities showed poorer physical functioning, health-related QoL, and emotional and social functioning than their counterparts without disabilities. Disability-specific associations with health were found: (a) physical disabilities and intellectual disabilities were associated with greater difficulties in ADL; (b) language impairment and Attention deficit/ hyperactivity disorder (ADHD) were negatively associated with sleep-related QoL; (c) all types of disabilities but hearing impairment were negatively associated with health-related QoL (HRQoL); and (d) language impairment, ADHD, internalizing disorder, as well as autism spectrum disorder were associated with greater abnormal behavioral difficulties. The findings warrant the development of tailor-made intervention programs and give insights to effective resource allocation for the children in need.

Insecure Adult Attachment and Child Maltreatment: A Meta-Analysis.

Extant evidence has shown that insecure adult attachment is related to dysfunctional parenting styles that heighten parents' risk of child maltreatment. However, there is a lack of studies appraising the evidence for the association between insecure adult attachment and child maltreatment. This meta-analytic study examined the relationship between parents' adult attachment and child maltreatment perpetration/child abuse potential. Studies examining the relationship between parents' adult attachment and child maltreatment/child abuse potential published before February 2017 were identified through a systematic search of online databases. In total, 16 studies (N = 1,830) were selected. Meta-analysis based on random-effects models shows a significant positive association between insecure attachment and child maltreatment (pooled effect size: odds ratio [OR] = 2.93, p = .000). Subgroup analyses show insecure attachment was more strongly associated with failure to thrive (OR = 8.04, p = .000) and filicide (OR = 5.00, p < .05). Medium effect sizes were found for subgroup analyses on insecure romantic attachment (OR = 3.76, p = .000), general attachment (OR = 3.38, p = .000), attachment to own child (OR = 3.13, p = .001), and to own parents (OR = 2.63, p = .000) in relation to child maltreatment.

Associating disabilities, school environments, and child victimization.

Inclusive education has become one of the key policy objectives for the education for children with disabilities in recent decades. However, its effectiveness in promoting happy school life among those children has been questioned. In this study, we aimed to provide a detailed profile of the associations between disabilities and child victimization, and to examine the effects of school environments on those associations. We conducted a cross-sectional survey with a sample of 4114 school-aged children (6-18 years), who were receiving primary or secondary education in Hong Kong in 2016-2017. Children's experiences of 7 types of victimization in the past year, status of disabilities, type of school attending, and other demographic factors were captured with questionnaire completed by the children or their parents. Apart from descriptive statistics, we conducted logistic regression analyses to examine the associations between disabilities, types of school, and child victimization. Children with ADHD, internalizing disorder, autistic spectrum disorder, and restrictions in body movement were at higher risks of victimization while other types of disabilities were not. Children attending special schools were at lower risks of victimization, while children with disabilities who had been placed in ordinary schools for inclusive education were at higher risks of most types of victimization when compared to children without disabilities. Our findings suggested an important role of the school environments on the associations between disabilities and victimization. When placed in a protective environment, children with disabilities could even be less vulnerable to victimization than those without disabilities.

Family poly-victimization and cyberbullying among adolescents in a Chinese school sample.

The sustained increase in their use of social networking facilitates the development of adolescents but comes with the risk of cyberbullying, which creates new challenges in regard to adolescent protection. Past evidence shows that family victimization may play an essential role in the way adolescents learn cyberbullying behaviors. Yet, research on the co-occurrence of family victimization and cyberbullying is limited. This study aims to investigate the associations between cyberbullying and family victimization among adolescents, and to examine the health correlates of cyberbullying and family poly-victimization. A large sample of 18,341 students, aged 15-17, from six cities in China, collected between 2009 and 2010 is employed in the present study, which investigated the association between various kinds of family victimization and adolescent cyberbullying. Data analysis was conducted in 2017. In-law conflict, intimate partner violence, elder abuse and neglect, and child maltreatment were associated with a higher possibility of children becoming internet victims. Parents' divorce and separation, low family income, mother's low level of education, and father's unemployment were all associated with cyberbullying victimization. Cyber victimization was positively correlated to symptoms of PTSD and depression, self-harm, and other physical and mental health variables. Possible explanations for the relationships found in this study are discussed and implications for future research and services are provided. Proactive screening for family poly-victimization and cyberbullying is suggested. Schools are highly recommended to cooperate with parents to promote cyber safety.

Evaluation of "Colorful Life": A Multi-Addiction Expressive Arts Intervention Program for Adolescents of Addicted Parents and Parents with Addiction.

This study evaluated an expressive arts intervention program ("Colorful Life") for adolescents with addicted parents and parents with addiction in Hong Kong. Different evaluation strategies were employed. Objective outcome evaluation adopting a one group pretest-posttest design showed positive changes in adolescents' (N = 43) beliefs about addiction. Both adolescents' and parents' (N = 21) psychosocial competencies were enhanced post-intervention. Subjective outcome evaluation from both adolescent (N = 47) and parent (N = 22) groups showed positive perceptions of the program content, implementers, and achievement of program objectives. Findings provided preliminary evidence to support and yielded practical implications for the adoption of the multi-addiction syndrome model, positive youth development, and expressive arts approaches in the development of interventions for high-risk adolescents and addictive parents.

Risk factors for child physical abuse and neglect among Chinese young mothers.

Although studies have reported a linkage between young pregnancy and child maltreatment risk, it is still unclear about what factors place young mothers at greater risk of maltreating their child in Chinese context. Based on the socio-ecological model, risk factors in 4 domains: family background/structure, maternal stressors, mother-child interaction, and child behavioral issue in relation to physical assault, neglect, both physical assault and neglect, and either physical assault or neglect among Chinese young mothers in Hong Kong were assessed. 392 young mothers were recruited from an integrated supportive program for young mothers. The mean age of mothers at delivery was 21.8 (SD=3.0) and 52.3% were married. Individual risk factors and cumulative risk domains related to different child maltreatment groups were examined. Our results show both overlapping and unique risk factors across the domains associated with physical assault and neglect. Further, young families exposed to higher number of risk domains show higher rates for physical assault and neglect, co-occurrence of physical assault and neglect, and either form of maltreatment. In addition, various risk domains were found to be particularly important for different forms of maltreatment: family background/structure domain was found to be an important risk domain for neglect; mother-child interaction domain for both physical assault and neglect; family background/structure and maternal stressors domains for either physical assault or neglect. Closer examination of a subgroup of adolescent mothers aged 18 and below shows that family background/structure was an important risk domain for this group.
