RESUMO

Fatty acids are vital for the survival of eukaryotes, but when present in excess can have deleterious consequences. The AMP-activated protein kinase (AMPK) is an important regulator of multiple branches of metabolism. Studies in purified enzyme preparations and cultured cells have shown that AMPK is allosterically activated by small molecules as well as fatty acyl-CoAs through a mechanism involving Ser108 within the regulatory AMPK ß1 isoform. However, the in vivo physiological significance of this residue has not been evaluated. In the current study, we generated mice with a targeted germline knock-in (KI) mutation of AMPKß1 Ser108 to Ala (S108A-KI), which renders the site phospho-deficient. S108A-KI mice had reduced AMPK activity (50 to 75%) in the liver but not in the skeletal muscle. On a chow diet, S108A-KI mice had impairments in exogenous lipid-induced fatty acid oxidation. Studies in mice fed a high-fat diet found that S108A-KI mice had a tendency for greater glucose intolerance and elevated liver triglycerides. Consistent with increased liver triglycerides, livers of S108A-KI mice had reductions in mitochondrial content and respiration that were accompanied by enlarged mitochondria, suggestive of impairments in mitophagy. Subsequent studies in primary hepatocytes found that S108A-KI mice had reductions in palmitate- stimulated Cpt1a and Ppargc1a mRNA, ULK1 phosphorylation and autophagic/mitophagic flux. These data demonstrate an important physiological role of AMPKß1 Ser108 phosphorylation in promoting fatty acid oxidation, mitochondrial biogenesis and autophagy under conditions of high lipid availability. As both ketogenic diets and intermittent fasting increase circulating free fatty acid levels, AMPK activity, mitochondrial biogenesis, and mitophagy, these data suggest a potential unifying mechanism which may be important in mediating these effects.

RESUMO

Complex interactions between noncoordinating residues are significant yet commonly overlooked components of macromolecular catalyst function. While these interactions have been demonstrated to impact binding affinities and catalytic rates in metalloenzymes, the roles of similar structural elements in synthetic polymeric catalysts remain underexplored. Using a model Suzuki-Miyuara cross-coupling reaction, we performed a series of systematic studies to probe the interconnected effects of metal-ligand cross-links, electrostatic interactions, and local rigidity in polymer catalysts. To achieve this, a novel bifunctional triphenylphosphine acrylamide (BisTPPAm) monomer was synthesized and evaluated alongside an analogous monofunctional triphenylphosphine acrylamide (TPPAm). In model copolymer catalysts, increased initial reaction rates were observed for copolymers untethered by Pd complexation (BisTPPAm-containing) compared to Pd-cross-linked catalysts (TPPAm-containing). Further, incorporating local rigidity through secondary structure-like and electrostatic interactions revealed nonmonotonic relationships between composition and the reaction rate, demonstrating the potential for tunable behavior through secondary-sphere interactions. Finally, through rigorous cheminformatics featurization strategies and statistical modeling, we quantitated relationships between chemical descriptors of the substrate and reaction conditions on catalytic performance. Collectively, these results provide insights into relationships among the composition, structure, and function of protein-mimetic catalytic copolymers.

RESUMO

"Giving the cells exactly what they need, when they need it" is the core idea behind the proposed bioprocess control strategy: operating bioprocess based on the physiological behavior of the microbial population rather than exclusive monitoring of environmental parameters. We are envisioning to achieve this through the use of genetically encoded biosensors combined with online flow cytometry (FCM) to obtain a time-dependent "physiological fingerprint" of the population. We developed a biosensor based on the glnA promoter (glnAp) and applied it for monitoring the nitrogen-related nutritional state of Escherichia coli. The functionality of the biosensor was demonstrated through multiple cultivation runs performed at various scales-from microplate to 20 L bioreactor. We also developed a fully automated bioreactor-FCM interface for on-line monitoring of the microbial population. Finally, we validated the proposed strategy by performing a fed-batch experiment where the biosensor signal is used as the actuator for a nitrogen feeding feedback control. This new generation of process control, -based on the specific needs of the cells, -opens the possibility of improving process development on a short timescale and therewith, the robustness and performance of fermentation processes.

RESUMO

Parents play a central role in children's ongoing participation and enjoyment of sport. Despite compelling evidence that parental behaviour can undermine the quality of children's experiences in sport, little research has examined whether strategies to support parents to engage in positive sports parenting behaviour are effective. In this paper, we report two studies that had the overall aim of developing, implementing and evaluating a program designed to promote positive parental involvement and improve spectator behaviour in junior rugby league in Australia. Study 1 involved the development of a prototype version of the program, named Play Well Triple P, which was qualitatively evaluated through interviews with 19 parents about their satisfaction with the program. In Study 2, we used feedback from Study 1 to refine the program and develop a pilot version, which was then evaluated in a quasi-experimental feasibility study with 101 parents (mean age = 38.42 years; 72% mothers) of junior rugby league players. The pilot version involved one interactive online module and text messages to reinforce content and prompt strategy implementation across the season. Participation in Play Well Triple P was associated with increased positive sports parenting behaviour and reduced controlling and intrusive sports parenting behaviour, with a trend towards reducing over-reactive parenting practices at home. These findings are discussed in relation to the feasibility of implementing a brief and engaging sports parenting intervention in the context of a broader integrated system designed to facilitate ongoing participation of children in sport.

RESUMO

AMP-activated protein kinase (AMPK) is a central energy sensor that coordinates the response to energy challenges to maintain cellular ATP levels. AMPK is a potential therapeutic target for treating metabolic disorders, and several direct synthetic activators of AMPK have been developed that show promise in preclinical models of type 2 diabetes. These compounds have been shown to regulate AMPK through binding to a novel allosteric drug and metabolite (ADaM)-binding site on AMPK, and it is possible that other molecules might similarly bind this site. Here, we performed a high-throughput screen with natural plant compounds to identify such direct allosteric activators of AMPK. We identified a natural plant dihydrophenathrene, Lusianthridin, which allosterically activates and protects AMPK from dephosphorylation by binding to the ADaM site. Similar to other ADaM site activators, Lusianthridin showed preferential activation of AMPKß1-containing complexes in intact cells and was unable to activate an AMPKß1 S108A mutant. Lusianthridin dose-dependently increased phosphorylation of acetyl-CoA carboxylase in mouse primary hepatocytes, which led to a corresponding decrease in de novo lipogenesis. This ability of Lusianthridin to inhibit lipogenesis was impaired in hepatocytes from ß1 S108A knock-in mice and mice bearing a mutation at the AMPK phosphorylation site of acetyl-CoA carboxylase 1/2. Finally, we show that activation of AMPK by natural compounds extends to several analogs of Lusianthridin and the related chemical series, phenanthrenes. The emergence of natural plant compounds that regulate AMPK through the ADaM site raises the distinct possibility that other natural compounds share a common mechanism of regulation.

RESUMO

Synthetic polymers are a modular solution to bridging the two most common classes of catalysts: proteins and small molecules. Polymers offer the synthetic versatility of small-molecule catalysts while simultaneously having the ability to construct microenvironments mimicking those of natural proteins. We synthesized a panel of polymeric catalysts containing a novel triphenylphosphine acrylamide monomer and investigated how their properties impact the rate of a model Suzuki-Miyaura cross-coupling reaction. Systematic variation of polymer properties, such as the molecular weight, functional density, and comonomer identity, led to tunable reaction rates and solvent compatibility, including full conversion in an aqueous medium. Studies with bulkier substrates revealed connections between polymer parameters and reaction conditions that were further elucidated with a regression analysis. Some connections were substrate-specific, highlighting the value of the rapidly tunable polymer catalyst. Collectively, these results aid in building structure-function relationships to guide the development of polymer catalysts with tunable substrates and environmental compatibility.

RESUMO

BACKGROUND: The COVID-19 pandemic disrupted the normality of daily life for many children, their families, and schools, resulting in heightened levels of anxiety, depression, social isolation, and loneliness among young people. An integrated public health model of interventions is needed to address the problem and to safeguard the mental health and wellbeing of children. The Triple P - Positive Parenting Program is one system of parenting support with a strong evidence-base and wide international reach. When implemented as a public health approach, Triple P has demonstrated population level positive effects on child wellbeing. This study will be the first large-scale, multi-site randomised controlled trial of a newly developed, low-intensity variant of Triple P, a school-based seminar series, as a response to the impacts of the pandemic. METHODS: The evaluation will employ an Incomplete Batched Stepped Wedge Cluster Randomised Trial Design. At least 300 Australian primary schools, from South Australia, Queensland, and Victoria will be recruited and randomised in three batches. Within each batch, schools will be randomly assigned to either start the intervention immediately or start in six weeks. Parents will be recruited from participating schools. The Triple P seminar series includes three seminars titled: "The Power of Positive Parenting", "Helping Your Child to Manage Anxiety", and "Keeping your Child Safe from Bullying". Parents will complete measures about child wellbeing, parenting, parenting self-regulation and other key intervention targets at baseline, six weeks after baseline, and 12 weeks after baseline. Intervention effectiveness will be evaluated with a Multilevel Piecewise Latent Growth Curve Modelling approach. Data collection is currently underway, and the current phase of the project is anticipated to be completed in January 2024. DISCUSSION: The findings from this study will extend the current knowledge of the effects of evidence-based parenting support delivered through brief, universally offered, low intensity, school-based parenting seminars in a post pandemic world. TRIAL REGISTRATION: The trial is registered at the Australian New Zealand Clinical Trials Registry (Trial Registration Number: ACTRN12623000852651).

RESUMO

Parents can be essential change-agents in their children's lives. To support parents in their parenting role, a range of programs have been developed and evaluated. In this paper, we provide an overview of the evidence for the effectiveness of parenting interventions for parents and children across a range of outcomes, including child and adolescent mental and physical health, child and adolescent competencies and academic outcomes, parental skills and competencies, parental wellbeing and mental health, and prevention of child maltreatment and family violence. Although there is extensive research showing the effectiveness of evidence-based parenting programs, these are not yet widely available at a population level and many parents are unable to access support. We outline how to achieve increased reach of evidence-based parenting supports, highlighting the policy imperative to adequately support the use of these supports as a way to address high priority mental health, physical health, and social problems.

RESUMO

The importance of champions in the implementation of evidence-based public health programs has been well established. Champions perform a range of behaviors which can have significant influence on the adoption and sustainability of interventions. This study investigates champion behaviors in parenting practitioners with the aim to provide insight into the range and extent that practitioners engage in champion behaviors and to examine predictors of practitioners' champion behaviors using structural equation modeling. Data were collected during a large international implementation survey of 1606 practitioners trained to deliver an evidence-based parenting program, the triple P-Positive Parenting Program. We developed a 13-item Champion Behaviors Scale which was administered alongside other measures of predictors of implementation outcomes. Perceived usefulness of the program was the most important facilitator of both public and personal champion behaviors. Certain desirable features of the program tended to not only be positively associated with the perceived usefulness of the program, but also had a unique impact on practitioners' personal champion behaviors. Higher positions within organizations were linked with more public champion behaviors. Although organizational support was found to be unrelated to champion behaviors in the structural model, it facilitated other predictors of champion behaviors.

RESUMO

PURPOSE: Sustained implementation is required for evidence-based parenting programs to promote children and their families' wellbeing at the societal level. Previous literature has examined the role of a range of different factors in enhancing sustainability. However, the inter-relationship between, and the relative importance of different factors remain largely unknown. The overall aim of this study is to identify predictors of sustained program use, the relative importance of factors, and potential mediation pathways. METHODS: We surveyed 1202 practitioners who were trained in at least one variant of the Triple P-Positive Parenting Program, at least one and half years before data collection. The present data were linked with data collected during professional training. We first examined the independent effect of each factor on sustained program use, then, developed and evaluated a structural equation model of sustained program use. RESULTS: The structural equation model explained a considerable amount of variance in sustained program use, with seven positive predictors and one negative predictor identified. Organisational support was identified as a key facilitator, which was not only positively linked with other facilitators but also had an independent positive effect. Perceived usefulness of the program was the most important practitioner-level facilitator, which might be contributed by both research-based evidence and practice-based evidence. Practitioners' self-regulation in program delivery impacted sustained use by influencing other factors such as perceived usefulness of the program. CONCLUSION: The findings provided insight into factors influencing the sustainability of evidence-based parenting programs which could be used to inform future implementation practice.

RESUMO

BACKGROUND: This study evaluated whether an evidence-based parenting intervention, when delivered online, could effectively address disruptive behavior problems in young children and yield outcomes comparable to in-person delivery of the same intervention. METHODS: Families (n = 334) of children (3-7 years; 63% White, 22% African American, 15% other races; 63% male) with disruptive behavior problems were randomized to online-delivered intervention (ODI) or staff-delivered intervention (SDI), resulting in baseline and demographic equivalence. Primary outcome measures for child disruptive behavior (independent observation, parent report) and secondary outcome measures of parenting and family impact were assessed at baseline, postintervention, and follow-up. Conducted using intent-to-treat (ITT) as well as per-protocol (PP) methods, noninferiority analyses, which drew on an HLM framework with repeat measures across three timepoints and on REML to provide unbiased estimates of model parameters, tested whether the outcome-difference CI did not exceed the a priori noninferiority margin. RESULTS: For ITT and PP analyses, the ODI was found to be noninferior to the SDI on the primary outcome: independently observed child disruptive behavior and parent-reported child behavior problems. The pattern for secondary outcomes was more varied: (a) noninferiority for observed positive and aversive parenting; (b) noninferiority for observed quality of parent-child relationship at post but not follow-up assessment; (c) noninferiority for parent-reported inappropriate/inconsistent discipline for PP but not ITT analyses; and (d) noninferiority not confirmed for parenting daily hassles and adverse family quality of life, despite large effect sizes for the ODI (Cohen's d .75-1.07). Finally, ODI noninferiority was found for teacher-reported child disruptive behavior. CONCLUSIONS: The tested online-delivered parenting intervention demonstrated clear noninferiority with the corresponding staff-delivered parenting intervention on the primary outcome, child disruptive behavior problems, and reflected substantial though nonuniform noninferiority and meaningful effect sizes for secondary outcomes related to parenting and family. Future research will guide optimization of online interventions.

RESUMO

Bullying victimisation is a serious risk factor for mental health problems in children and adolescents. School bullying prevention programs have consistently produced small to moderate reductions in victimisation and perpetration. However, these programs do not necessarily help all students affected by bullying. Paradoxically whole-school programs lead to higher levels of depression and poorer self-esteem for students who continue to be victimised after program implementation. This may be because some elements of whole-school programs make victims more visible to their peers, thus further eroding their peer social status. Three main identified risk factors for children and adolescents who continue to be victimised following school bullying prevention programs are peer rejection, internalising problems, and lower quality parent-child relationships. All are potentially modifiable through family interventions. A large body of research demonstrates the influence of families on children's social skills, peer relationships and emotional regulation. This paper describes the theoretical foundations and empirical evidence for reducing the incidence and mental health outcomes of school bullying victimisation through family interventions. Family interventions should be available to complement school efforts to reduce bullying and improve the mental health of young people.

RESUMO

OBJECTIVE: Developing an effective population-level system of evidence-based parenting support capable of shifting (at a population level) rates of child maltreatment and social, emotional, and behavioral problems in children requires an integrated theory of change. This paper presents a systems-contextual model of change and identifies modifiable mechanisms that can potentially explain population-level changes in parenting and child outcomes. METHOD: Using the Triple P-Positive Parenting Program as an exemplar of a tiered, multi-level system of evidence-based parenting interventions, we discuss the putative mechanisms of change necessary to produce change in child behavior, parenting, practitioner behavior, and organizational changes to support the sustained implementation of an intervention. RESULTS: A model of change is proposed that blends theoretical perspectives derived from social learning theory, self-regulation theory, applied behavior analysis, cognitive behavior principles, developmental theory, and principles derived from the fields of public health, implementation science, and economics to explain change in the behavior at the community wide level. Different types of interventions targeting different populations and mechanisms are used to illustrate how sustainable change in child and parent outcomes can be achieved. CONCLUSIONS: Evidence supporting specific mechanisms and moderators of intervention effects are discussed as well as directions for future research on mechanisms.

RESUMO

PURPOSE: This study assesses postoperative quality-of-life outcomes via the Glasgow Benefit Inventory (GBI) in patients undergoing transnasal endoscopic pituitary surgery for pituitary adenoma. METHODS: This was a retrospective cohort study in a UK tertiary referral centre. 145 patients who had undergone transnasal endoscopic pituitary surgery for pituitary adenoma over a 6-year period at one institution completed the GBI with at least 3 months' follow up. Patients with prior radiotherapy were excluded. The GBI is a patient-reported outcome measure that assesses post-intervention outcomes in three domains: 'general' functioning, 'social support' and 'physical' functioning. Pre- and post-operative visual loss scores were additionally assessed via a 1-5 Likert scale. GBI scores were assessed alongside these visual loss scores, clinical and surgical parameters and demographics. RESULTS: Mean age was 59.5 years (range 20-87 years) and mean follow up was 36 months. A total of 46 of 145 (31.7%) patients had secreting tumours. The most common primary symptom was visual loss. Mean total score for all patients was positive (+8.4); with 'general' domain score the most positive (+10.5). All patient groups had overall positive, 'general' and 'social support' domain scores. Patients with Cushing's disease reported significantly higher mean total scores (+29.6) than all other groups. Acromegaly (+7.9) and non-functioning adenoma (NFA) groups (+5.2) reported lower mean total scores. 'Physical' domain mean scores were negative for acromegaly and NFA groups. There was statistical significance between a pre- to post-operative improvement in visual score and mean total GBI score (p = 0.02) and mean 'general' domain GBI score (p = 0.02). CONCLUSIONS: These findings can aid preoperative counselling of patients undergoing this surgery. Those with NFA and no anticipated improvement to visual loss symptoms may be advised of possible worsened physical outcomes and of the option to delay the surgery until symptoms are present.

RESUMO

Of all the potentially modifiable influences affecting children's development and mental health across the life course, none is more important than the quality of parenting and family life. In this position paper, we argue that parenting is fundamentally linked to the development of life skills that children need in order to achieve the United Nations Sustainable Development Goals. We discuss key principles that should inform the development of a global research and implementation agenda related to scaling up evidence-based parenting support programs. Research over the past 50 years has shown that parenting support programs of varied intensity and delivery modality can improve a wide range of developmental, emotional, behavioral and health outcomes for parents and their children. Such findings have been replicated across culturally and socioeconomically diverse samples, albeit primarily in studies from Western countries. We highlight the evidence for the relevance of parenting interventions for attaining the SDGs globally, and identify the barriers to and strategies for achieving their scale-up. The implications of the global COVID-19 pandemic for the delivery of evidence-based parenting support are also discussed.

RESUMO

Identify predictors of maternal bonding and responsiveness for mothers of very preterm infants (< 32 weeks gestational age) at 6 weeks and 12 months corrected-age (CA). Cross-sectional and longitudinal study containing 39 mothers of very preterm infants. At 6 weeks CA maternal self-efficacy made a significant unique contribution to the variance in self-reported maternal bonding and responsiveness (21% and 26%, respectively). At 12 months CA maternal trauma symptoms, depressive symptoms and self-efficacy made a significant unique contribution to the variance in bonding (14%, 9% and 9%, respectively). Maternal self-efficacy made a significant 31% unique contribution to the variance in responsiveness. The combined effects of maternal trauma symptoms, depressive symptoms and self-efficacy at 6 weeks CA predicted maternal responsiveness at 12 months CA (p = .042). Supporting maternal self-efficacy is key to facilitating bonding and responsiveness up to 12 months CA following a very preterm birth.Trial registration: Australian New Zealand Clinical Trials Registry: ACTRN12612000194864.

RESUMO

OBJECTIVE: To assess whether preoperative gonioscopy status is associated with the development of postoperative glaucoma after phacoemulsification. PROCEDURE: Eligible dogs and eyes were selected from medical records (2007-2017), and each eye was classified as having normal or abnormal gonioscopy status. Records were examined for postoperative glaucoma, and data were collected for baseline variables including patient signalment, surgical factors, and pre, intra, and postoperative medications. RESULTS: Of 305 dogs (505 eyes) selected for review in this study, 111 dogs (163 eyes) had abnormal gonioscopy findings, and 194 dogs (342 eyes) had normal gonioscopy findings. Postoperative glaucoma occurred in 24% (39/163) of eyes with abnormal gonioscopy and in 14% (49/342) eyes with normal gonioscopy. Eyes with abnormal gonioscopy status were at higher risk of postoperative glaucoma compared to normal eyes (P = .025). There was no important confounding due to the numerous baseline variables summarised above. Regardless of gonioscopy status, the risk of glaucoma was highest during the first 2 months after surgery. CONCLUSIONS: Eyes with abnormal gonioscopy findings are at increased risk of postoperative glaucoma compared with eyes with normal gonioscopy findings. Gonioscopy is recommended as a part of presurgical assessment in all dogs prior to phacoemulsification. Further study is needed to assess whether the incidence of postoperative glaucoma can be reduced by increased monitoring or altered treatment protocols in cases that are known to have abnormal gonioscopy findings prior to cataract surgery.

RESUMO

Shared care between parents and grandparents is common in Asian cultures. This cocare practice provides many benefits to families but is also particularly complex, as both parents and grandparents must simultaneously fulfill their roles as cocaregivers as well as maintain their relationship with each other. This study aims to explore the determinants of coparenting relationships between parents and grandparents in Vietnam. Data were collected from 501 Vietnamese parents whose aging parents are active carers for their children. The results indicated that grandparent psychological control and parent-grandparent quality of communication explain the largest variance in both parent-grandparent coparenting conflict and cooperation. The results suggest that parenting interventions aimed at the Asian cultures, where grandparent care is common, may benefit from the inclusion of a content focus on promoting the coparenting relationship between parents and grandparents.


El cuidado compartido entre abuelos y padres es común en las culturas asiáticas. Esta práctica de cocuidado ofrece muchos beneficios a las familias pero también es particularmente compleja, ya que tanto los padres como los abuelos deben cumplir sus roles simultáneamente como cocuidadores y también mantener su relación mutua. Este estudio tiene como finalidad analizar los determinantes de las relaciones de cocrianza entre los padres y los abuelos en Vietnam. Se recopilaron datos de 501 padres vietnamitas cuyos padres de la tercera edad son cuidadores activos de sus hijos. Los resultados indicaron que el control psiscológico de los abuelos y la calidad de la comunicación entre los padres y los abuelos explican la mayor varianza en el conflicto y la cooperación en la cocrianza entre padres y abuelos. Los resultados sugieren que las intervenciones en la crianza orientadas a las culturas asiáticas, donde el cuidado de los abuelos es común, pueden beneficiarse de la inclusión de un contenido centrado en promover la relación de cocrianza entre padres y abuelos.

RESUMO

OBJECTIVE: To determine the efficacy of a hospital-based intervention that transitions into existing community support, in enhancing developmental outcomes at 2 years of corrected age in infants born at less than 32 weeks. STUDY DESIGN: In total, 323 families of 384 infants born <32 weeks were randomized to receive intervention or care-as-usual. The intervention teaches parents coping skills, partner support, and effective parenting strategies over 4 hospital-based and 4 home-phone sessions. At 2 years of corrected age maternally reported child behavior was assessed by the Infant and Toddler Social Emotional Adjustment Scale. Observed child behavior was coded with the Revised Family Observation Schedule. Cognitive, language, and motor skills were assessed with the Bayley Scales of Infant and Toddler Development III. RESULTS: Mean gestational age of infants was 28.5 weeks (SD = 2.1), and mothers' mean age was 30.6 years (SD = 5.8). A total of 162 families (n = 196 infants) were allocated to intervention and 161 families (n = 188 infants) received care-as-usual. There was no significant adjusted difference between treatment groups on dysregulation (0.2; 95% CI -2.5 to 3.0, P = .9) externalizing (0.3; 95% CI -1.6 to 2.2, P = .8), internalizing (-1.5; 95% CI -4.3 to 1.3, P = .3), observed aversive (0.00; -0.04 to 0.04, P = .9), or nonaversive behavior (-0.01; 95% CI -0.05 to 0.03, P = .7). Intervention children scored significantly higher on cognition (3.5; 95% CI 0.2-6.8, P = .04) and motor skill (5.5; 95% CI 2.5-8.4, P < .001), and approached significance on language (3.8; 95% CI -0.3 to 7.9, P = .07). CONCLUSIONS: Baby Triple P for Preterm Infants increases cognitive and motor skills but does not impact behavior. The results are evidence that hospital-based interventions can improve some developmental outcomes for infants <32 weeks. TRIAL REGISTRATION: ACTRN 12612000194864.

RESUMO

BACKGROUND: The quality of the family environment-in particular, the kind of parenting children receive in their early years-plays a critical role in influencing children's growth and development. To facilitate the development and delivery of appropriate parenting and family interventions for Chinese parents, this study explores the prevalence of the difficulties that may arise in the course of child-rearing, the associated sociodemographic factors and parents' help-seeking behavior. METHODS: A cross-sectional self-reporting survey was conducted with a sample of 2229 parents of children between 6 and 35 months of age. Using a stratified random-digit design, parents from 15 Chinese cities were surveyed to determine their child-rearing difficulties, support-seeking behavior and their preferences for service delivery. The sociodemographic factors that influenced major child-rearing difficulties were analyzed using bivariate and logistic analyses. RESULTS: The majority (87.5%) of Chinese parents of children aged 6-35 months reported experiencing child-rearing difficulties. Nearly one third (31.5%) of parents reported experiencing major difficulties. Feeding and sleep problems were most often reported. Regression analysis revealed that major child-rearing difficulties most often involved male children (OR = 1.35, 95% CI 1.11-1.64), single-child households (OR = 1.38, 95% CI 1.07-1.77), and households with financial problems (OR = 1.40, 95% CI 1.06-1.85). Just over one third of parents (33.44%) sought professional support, while 21.37% had attended a parenting course in the past year. Prefer ways of sourcing parental support included professional online platform (69.24%), self-help books (43.70%), face-to-face consultation (24.99%), and attending lectures (36.57%). CONCLUSIONS: Child-rearing difficulties are common among parents of children between 6 and 35 months of age in Chinese cities. The family with boys, single-child, financial problems, and father not joining in child-rearing may face the high risk to major child-rearing difficulties. The national initiative to provide more guidance and support for child-rearing difficulties is worthwhile, as is the development of online parenting programs.
