Effects of a novel positive psychological intervention on prenatal stress and well-being: A pilot randomised controlled trial

PROBLEM Low prenatal well-being has adverse outcomes for mother and infant but few interventions currently exist to promote and maintain prenatal well-being. BACKGROUND Mindfulness and gratitude based interventions consistently demonstrate benefits in diverse populations. Interventions integrating these constructs have potential to improve psychological and physiological health during pregnancy. AIM The aim of this pilot study is to examine the effect of a novel gratitude and mindfulness based intervention on prenatal stress, cortisol levels, and well-being. METHODS A pilot randomised controlled trial was conducted with 46 pregnant women. Participants used an online mindfulness and gratitude intervention 4 times a week for 3 weeks. Measures of prenatal stress, salivary cortisol, gratitude, mindfulness, and satisfaction with life were completed at baseline, 1.5 weeks later, and 3 weeks later. FINDINGS Intervention participants demonstrated significant reductions in prenatal stress in comparison to the control condition (p=.04). Within subjects reductions in waking (p=.004) and evening cortisol (p>.001) measures were observed for intervention participants. Significant effects were not observed for other well-being outcomes. DISCUSSION Reducing self-report and physiological stress in pregnancy can improve maternal and infant outcomes. The findings of this pilot study indicate potential direct effects of the intervention on self-reported stress in comparison to a treatment-as-usual control. Effects on a biomarker of stress, cortisol, were also observed within the intervention group. CONCLUSION A brief mindfulness and gratitude based intervention has the potential to reduce stress in pregnancy. Future research is needed to further explore mechanisms and potential benefits of such interventions.

The role of prenatal, obstetric, and post-partum factors in the parenting stress of mothers and fathers of 9-month old infants

Abstract Introduction: The aim of this paper was to examine the role of perinatal, obstetric and post partum factors on maternal and paternal stress. It will present the first examination of the role of prenatal, obstetric, post-partum, and demographic variables in parenting stress for mothers and fathers at 9 months. Methods: Data from 6821 parental dyads of 9-month-old infants were extracted from the Growing Up in Ireland National Longitudinal Study of Children. Participants completed the Parental Stress Scale, the Dyadic Adjustment Scale, the Quality of Attachment Sub-scale from the Maternal and Paternal Postnatal Attachment Scales, and a single item health status question from the Short Form 12 Health Survey. Information on prenatal care, pregnancy complications, obstetric outcomes, infant health, and participant demographics were also collected. Separate hierarchical linear regressions were conducted for mothers and fathers Results: Mothers reported higher levels of parenting stress than fathers (p < 0.001). Maternal parenting stress was predicted by attachment, own health status, average sleep, occupation, household income, and having a very rapid labor. Paternal parenting stress was predicted by attachment and own health status. Discussion: A range of perinatal factors was associated with an increased risk of higher parenting stress at 9 months post-partum and the roles of these factors differ between mothers and fathers. These findings are important for predicting and reducing risk of parenting stress in both genders.

Effects of healthcare professional delivered early feeding interventions on feeding practices and dietary intake: A systematic review

BACKGROUND Childhood obesity is a global public health challenge. Parental feeding practices, such as responsive feeding, are implicated in the etiology of childhood obesity. PURPOSE This systematic review aimed to examine of effects of healthcare professional-delivered early feeding interventions, on parental feeding practices, dietary intake, and weight outcomes for children up to 2 years. The role of responsive feeding interventions was also specifically examined. METHODS Databases searched included: CINAHL, the Cochrane Library, EMBASE, Medline, PubMed, PsycINFO, and Maternity and Infant Care. INCLUSION CRITERIA participants are parents of children ≤2 years; intervention includes focus on early child feeding to prevent overweight and obesity; intervention delivered by healthcare professionals. RESULTS Sixteen papers, representing 10 trials, met inclusion criteria for review. Six interventions included responsive feeding components. Interventions demonstrated inconsistent effects on feeding practices, dietary intake, and weight outcomes. Findings suggest some reductions in pressure to eat and infant consumption of non-core beverages. Responsive feeding based interventions demonstrate greater improvements in feeding approaches, and weight outcomes. CONCLUSIONS The findings of this review highlight the importance of incorporating responsive feeding in healthcare professional delivered early feeding interventions to prevent childhood obesity. Observed inconsistencies across trials may be explained by methodological limitations.

The association between childcare arrangements and risk of overweight and obesity in childhood: a systematic review

Over 80% of preschool‐aged children experience non‐parental childcare. Childcare type has the potential to influence weight outcomes, but its impact on childhood overweight/obesity is not well established. This review aims to (i) systematically evaluate the effects of childcare type on childhood overweight/obesity risk and (ii) investigate the impact of childcare intensity and age at commencement. Five electronic databases were searched for observational studies quantifying an association between childcare type ≤5 years and weight outcomes <18 years. Twenty‐four studies were included (n = 127,529 children). Thirteen studies reported increased risk of overweight/obesity in children attending informal care (n = 9) or centre care (n = 4) vs. parental care. Seven studies reported decreased risk of overweight/obesity for children in centre vs. ‘non‐centre’ care (parental and informal). Four studies reported no association between informal or centre care and overweight/obesity. Early (<3 years) informal care, especially by a relative, was associated with increased risk of overweight/obesity. Higher intensity childcare, especially when commenced early (<1 year), increased overweight/obesity risk. Later (≥3 years) centre care was associated with decreased risk of overweight/obesity. Early informal care, earlier commencement age and higher intensity represent a risk for childhood obesity. Exploration of the obesogenic aspects of these contexts is essential to inform preventative measures.

Parental experiences and perceptions of infant complementary feeding: a qualitative evidence synthesis: Infant complementary feeding experiences and perceptions

Interventions to prevent childhood obesity increasingly focus on infant feeding, but demonstrate inconsistent effects. A comprehensive qualitative evidence synthesis is essential to better understand feeding behaviours and inform intervention development. The aim of this study is to synthesize evidence on perceptions and experiences of infant feeding and complementary feeding recommendations.

Parental experiences and perceptions of infant complementary feeding: a qualitative evidence synthesis.

Background: Current childhood obesity interventions increasingly focus on infant feeding but often do so without considering parental perceptions and experiences. Qualitative research on infant feeding has yet to be systematically evaluated to inform intervention development. A qualitative evidence synthesis (QES) of the extant literature focusing on experiences, barriers and facilitators to healthy infant feeding and feeding guideline adherence is therefore crucial. Methods: A QES of papers examining caregivers’ experiences of complementary feeding and weaning of infants (< 2 years) was conducted. Twenty-three papers, comprising 1047 participants, were included in the QES. A ‘Best Fit’ Framework Synthesis approach, with the COM-B model as the analysis framework, was used. Themes emerging from the data that were not accounted for by the COM-B model were added to the coding framework. Results: Beliefs about health and behavioural outcomes, and daily pressures and time constraints, are important considerations for parental feeding approaches. Infant feeding guidelines and advice are more likely valued and adhered to when they are consistent, from a trusted and experienced source, and are compatible with caregiver experiences. The role of ‘maternal instinct’ guides much infant feeding and often justifies lack of adherence to feeding guidelines. Discussion: The key factors in infant feeding relate to presentation and trust in infant feeding advice. How guidelines correspond to feeding beliefs, experiences and beliefs about capabilities further influence parental engagement in healthy feeding practices. The findings of this review highlight key areas for intervention to help improve infant feeding for childhood overweight and obesity.

Study within a trial (SWAT) protocol. Participants' perspectives and preferences on clinical trial result dissemination: The TRUST Thyroid Trial experience

Introduction Dissemination of results of randomised controlled trials is traditionally limited to academic and professional groups rather than clinical trial participants. While there is increasing consensus that results should be communicated to trial participants, there is a lack of evidence on the most appropriate methods of dissemination. This study within a trial (SWAT) aims to address this gap by using a public and patient involvement (PPI) approach to identify, develop and evaluate a patient-preferred method of receiving trial results of the Thyroid Hormone Replacement for Subclinical Hypothyroidism Trial (TRUST). Methods An experimental (intervention) study will be conducted using mixed methods to inform the development of and evaluation of a patient-preferred method of communication of trial results. The study will involve three consecutive phases. In the first phase, focus groups of trial participants will be conducted to identify a patient-preferred method of receiving trial results. The method will be developed and then assessed and refined by a patient and public expert group. In the second phase participants will be randomly assigned to the intervention (patient-preferred method) and comparison groups (standard dissemination method as developed by the lead study site in Glasgow, Scotland). In the third phase, a quantitative questionnaire will be used to measure and compare patient understanding of trial results between the two groups. Discussion This protocol provides a template for other trialists who wish to enhance patient and public involvement and additionally, will provide empirical evidence on how trialists should best disseminate study results to their participants.

Physical and psychosomatic health outcomes in people bereaved by suicide compared to people bereaved by other modes of death: a systematic review

BackgroundLittle research has been conducted into the physical health implications of suicide bereavement compared to other causes of death. There is some evidence that suicide bereaved parents have higher morbidity, particularly in terms of chronic illness. This systematic review aims to examine the physical and psychosomatic morbidities of people bereaved by a family member’s suicide and compare them with family members bereaved by other modes of death.MethodsMEDLINE, EMBASE, CINAHL, and PsycINFO were searched from 1985 to February 2016. The search was re-run in March 2017. Peer-reviewed English language articles comparing suicide-bereaved family members to non-suicide bereaved family members on measures of physical or psychosomatic health were eligible for inclusion. Cohort, cross-sectional, case-control and cohort-based register studies were eligible for inclusion. A modified version of the Newcastle Ottawa Scale was used for quality assessment. Results were synthesised using narrative synthesis.ResultsThe literature search located 24 studies which met the inclusion criteria. Seven studies found statistically significant associations between physical health and suicide bereavement. Five of the studies found that suicide-bereaved family members were more likely to experience pain, more physical illnesses and poorer general health. They were also at increased risk of cardiovascular disease, hypertension, diabetes and chronic obstructive pulmonary disease. In contrast, another study in Denmark found that those bereaved by suicide had a lower risk of a number of physical health disorders, including cancers, diabetes, cardiovascular and chronic lower respiratory tract disorders compared to those bereaved by other causes of death. Additionally, a further study conducted in the United States found that suicide-bereaved children visited a GP less frequently than non-suicide bereaved children.ConclusionsReview findings are relevant for clinicians working with people bereaved by suicide as they highlight that such clients are at increased risk of several adverse physical health outcomes. Future research should examine health risk behaviours of suicide-bereaved and non-suicide bereaved family members as they may confound the association between exposure and outcome.Trial RegistrationsThe review protocol has been registered on PROSPERO, registration number CRD42016030007.

Surveying knowledge, practice and attitudes towards intervention fidelity within trials of complex healthcare interventions

BackgroundIntervention fidelity is the degree to which interventions have been implemented as intended by their developers. Assessing fidelity is crucial for accurate interpretation of intervention effectiveness, but fidelity is often poorly addressed within trials of complex healthcare interventions. The reasons for this are unclear, and information on the use of methods to enhance and assess fidelity in trials of complex interventions remains insufficient. This study aimed to explore the knowledge, practice and attitudes towards intervention fidelity amongst researchers, triallists and healthcare professionals involved with the design and conduct of trials of complex healthcare interventions.MethodsAn online survey consisting of closed and open-ended questions exploring four sections (Demographics, Fidelity knowledge, Practice and Attitudes) was conducted. This was an opportunistic sample of individuals with experience of direct involvement in trials of complex healthcare interventions (e.g. design/development, conduct, evaluation).ResultsData from 264 participants representing 15 countries were analysed. The majority (65.9%, n = 174) of participants identified themselves as ‘Researchers’. The majority of participants were familiar with the term “intervention fidelity” (69.7%, n = 184) and indicated that fidelity is important (89.7%, n = 236). Mean self-reported understanding of fidelity was moderate. Although 68% (n = 182) had previously used strategies to assess (e.g. audio/video-recording sessions) and enhance (e.g. training manual) fidelity in trials of complex interventions, only a limited proportion of participants indicated always reporting these strategies in subsequent publications (30.9%, n = 56). Poor knowledge or understanding was the most commonly cited barrier to addressing intervention fidelity in trials (77.4%, n = 202). Over half of respondents (52.1%, n = 137) had never completed specific fidelity training or research, and the vast majority (89.7%, n = 236) would welcome specific training in this area.ConclusionDespite good awareness of intervention fidelity and its importance, poor knowledge and understanding appears to be a key factor limiting how intervention fidelity is addressed in trials of complex interventions. Participants identified a need for further training and education in this area. Additionally, clarification of the terminology, definition and components of intervention fidelity would facilitate better understanding of the concept. A discrepancy between participants’ use of fidelity strategies and subsequent reporting raises concerns around inadequate fidelity reporting in the trials literature.

Do mothers accurately identify their child’s overweight/obesity status during early childhood? Evidence from a nationally representative cohort study

BackgroundMaternal recognition of overweight/obesity during early childhood is a key determinant in achieving healthy weight status in children. The aim of this study is to 1) investigate maternal perceptions of their child weight, focusing on whether or not mothers accurately identify if their child is overweight or obese at three years old and five years old; 2) identify the factors influencing maternal misperceptions regarding their child’s weight at three years old and five years old, 3) ascertain if a failure to recognize overweight/obesity at three years old is associated with the likelihood of doing so at five years old.MethodsUsing two waves of the longitudinal Growing Up in Ireland study data regarding child, maternal, and household characteristics as well as healthcare access and utilization variables were obtained for mothers when their children are three and five years old respectively. Multivariate logistic analysis was used to examine the factors associated with mothers inaccurately perceiving their child to be of normal weight status when the child is in fact either clinically overweight or obese.ResultsIn wave 2, 22% of mothers failed to accurately identify their child to be overweight or obese. This inaccuracy decreased to 18% in wave 3. A failure of mothers to identify their child’s overweight/obesity was more likely to occur if the child was a girl (OR: 1.25) (OR: 1.37), had a higher birth weight (OR:1.00), if the mother was obese (OR: 1.50), (OR: 1.72) or working (OR:1.25) (OR:1.16) in wave 2 and wave 3, respectively. Other factors affecting the odds of misperceiving child’s weight include gestation age, income and urban living.ConclusionThese findings suggest that mothers of overweight or obese three and five year olds show poor awareness of their child’s weight status. Both child and mother characteristics play a role in influencing this awareness. Mothers unable to accurately identify their child’s overweight or obesity status at three years old are likely to do again when the child is five years old. This study highlights the need for increased support to help improve mothers’ understanding of healthy body size in preschool aged children.
