Development of an outcome indicator framework for a universal health visiting programme using routinely collected data.

BACKGROUND: Universal health visiting has been a cornerstone of preventative healthcare for children in the United Kingdom (UK) for over 100 years. In 2016, Scotland introduced a new Universal Health Visiting Pathway (UHVP), involving a greater number of contacts with a particular emphasis on the first year, visits within the home setting, and rigorous developmental assessment conducted by a qualified Health Visitor. To evaluate the UHVP, an outcome indicator framework was developed using routine administrative data. This paper sets out the development of these indicators. METHODS: A logic model was produced with stakeholders to define the group of outcomes, before further refining and aligning of the measures through discussions with stakeholders and inspection of data. Power calculations were carried out and initial data described for the chosen indicators. RESULTS: Eighteen indicators were selected across eight outcome areas: parental smoking, breastfeeding, immunisations, dental health, developmental concerns, obesity, accidents and injuries, and child protection interventions. Data quality was mixed. Coverage of reviews was high; over 90% of children received key reviews. Individual item completion was more variable: 92.2% had breastfeeding data at 6-8 weeks, whilst 63.2% had BMI recorded at 27-30 months. Prevalence also varied greatly, from 1.3% of children's names being on the Child Protection register for over six months by age three, to 93.6% having received all immunisations by age two. CONCLUSIONS: Home visiting services play a key role in ensuring children and families have the right support to enable the best start in life. As these programmes evolve, it is crucial to understand whether changes lead to improvements in child outcomes. This paper describes a set of indicators using routinely-collected data, lessening additional burden on participants, and reducing response bias which may be apparent in other forms of evaluation. Further research is needed to explore the transferability of this indicator framework to other settings.

Working mechanisms of the use and acceptability of ecological momentary interventions: a realist evaluation of a guided self-help ecological momentary intervention targeting self-esteem.

BACKGROUND: Technology improves accessibility of psychological interventions for youth. An ecological momentary intervention (EMI) is a digital intervention geared toward intervening in daily life to enhance the generalizability and ecological validity, and to be able to intervene in moments most needed. Identifying working mechanisms of the use of ecological momentary interventions might generate insights to improve interventions. METHODS: The present study investigates the working mechanisms of the use and acceptability of an ecological momentary intervention, named SELFIE, targeting self-esteem in youth exposed to childhood trauma, and evaluates under what circumstances these mechanisms of use and acceptability do or do not come into play. A realist evaluation approach was used for developing initial program theories (data: expert interviews and a stakeholders focus group), and subsequently testing (data: 15 interviews with participants, a focus group with therapists, debriefing questionnaire), and refining them. RESULTS: The SELFIE intervention is offered through a smartphone application enabling constant availability of the intervention and thereby increasing accessibility and feasibility. When the intervention was offered on their personal smartphone, this enhanced a sense of privacy and less hesitance in engaging with the app, leading to increased disclosure and active participation. Further, the smartphone application facilitates the practice of skills in daily life, supporting the repeated practice of exercises in different situations leading to the generalizability of the effect. Buffering against technical malfunction seemed important to decrease its possible negative effects. CONCLUSIONS: This study enhanced our understanding of possible working mechanisms in EMIs, such as the constant availability supporting increased accessibility and feasibility, for which the use of the personal smartphone was experienced as a facilitating context. Hereby, the current study contributes to relatively limited research in this field. For the field to move forward, mechanisms of use, and acceptability of EMIs need to be understood. It is strongly recommended that alongside efficacy trials of an EMI on specific target mechanisms, a process evaluation is conducted investigating the working mechanisms of use. TRIAL REGISTRATION: The current paper reports on a realist evaluation within the SELFIE trial (Netherlands Trial Register NL7129 (NTR7475)).

Reducing hospital readmissions amongst people experiencing homelessness: a mixed-methods evaluation of a multi-disciplinary hospital in-reach programme.

INTRODUCTION: People experiencing homelessness are at increased risk of experiencing ill-health. They are often readmitted to hospital after discharge, usually for the same or similar reasons for initial hospitalisation. One way of addressing this issue is through hospital in-reach initiatives, which have been established to enhance the treatment and discharge pathways that patients identified as homeless receive after hospital admission. Since 2020, the Hospital In-reach programme (which involves targeted clinical interventions and structured discharge support) has been piloted in two large National Health Service (NHS) hospitals in Edinburgh, United Kingdom (UK). This study describes an evaluation of the programme. METHODS: This evaluation used a mixed method, pre-post design. To assess the effect of the programme on hospital readmission rates from baseline (12 months pre-intervention) and follow-up (12 months post-intervention), aggregate data describing the proportions of homeless-affected individuals admitted to hospital during the evaluation period were analysed using Wilcoxon signed rank test, with level of significance set at p = 0.05. Qualitative interviews were conducted with fifteen programme and hospital staff (nurses, general practitioners, homeless link workers) to assess the processes of the programme. RESULTS: A total of 768 referrals, including readmissions, were made to the In-reach programme during the study period, of which eighty-eight individuals were followed up as part of the study. In comparison to admissions in the previous 12 months, readmissions were significantly reduced at 12 months follow-up by 68.7% (P = 0.001) for those who received an in-reach intervention of any kind. Qualitative findings showed that the programme was valued by hospital staff and homeless community workers. Housing services and clinical staff attributed improvements in services to their ability to collaborate more effectively in secondary care settings. This ensured treatment regimens were completed and housing was retained during hospital admission, which facilitated earlier discharge planning. CONCLUSIONS: A multidisciplinary approach to reducing readmissions in people experiencing homelessness was effective at reducing readmissions over a 12-month period. The programme appears to have enhanced the ability for multiple agencies to work more closely and ensure the appropriate care is provided for those at risk of readmission to hospital among people affected by homelessness.

Smokers' user experience of smoking cessation apps: A systematic review.

OBJECTIVES: To explore how smokers view common functions and characteristics of smoking cessation apps. DESIGN: Systematic review. SEARCH SOURCES: CINAHL PLUS, MEDLINE, PsycINFO, EMBASE, IEEE Xplore, ACM Digital Library, and Google Scholar. REVIEW METHODS: Seven digital databases were searched separately using relevant search terms. Search results were uploaded to Covidence. Inclusion and exclusion criteria were identified with the expert team in advance. Titles, abstracts, and full texts were screened by two reviewers independently. Any disagreements were discussed in research meetings. Pertinent data were extracted and analysed using qualitative content analysis. Findings were presented in a narrative approach. RESULTS: 28 studies were included in this review. The overarching themes were app functionality and app characteristics. Under app "functionality", six subthemes emerged: 1) education; 2) tracking; 3) social support; 4) compensation; 5) distraction, and 6) reminding. Under "app characteristics", five subthemes emerged: 1) simplification, 2) personalisation, 3) diverse content forms, 4) interactivity, and 5) privacy and security. CONCLUSION: Understanding user needs and expectations is crucial for developing a programme theory for smoking cessation app interventions. Relevant needs identified in this review should be linked to broader theories of smoking cessation and app-based intervention.

Challenges and possible solutions for accessing scholarly literature among medical and nursing professionals and students in low-and-middle income countries: A systematic review.

BACKGROUND: Access to high quality research literature is essential for educating nursing and healthcare students to promote evidence-based practice. Within Low- and Middle-Income countries (LMICs) access is limited due to financial and structural constraints within countries and institutions. Reduced access to research literature limits the achievement of the Sustainable Development Goals through its impact on the education of healthcare staff and on the development of contextually appropriate evidence for practice. OBJECTIVE: To identify the challenges and possible solutions for accessing scholarly literature among medical and nursing professionals and students in low-and-middle income countries. DESIGN: Systematic review. DATA SOURCES: Searches were conducted in MEDLINE, CINAHL PLUS, ERIC, ASSIA, EMBASE, and Google Scholar. REVIEW METHODS: Five bibliography databases were searched using relevant search terms, from January 2002 to July 2022. Additional searches were carried out in Google Scholar. Titles, abstracts, and full texts were independently screened by at least two authors, based on predefined eligibility criteria. Pertinent data were extracted from included studies, and critical appraisal was undertaken. Data were analysed and presented in a narrative approach. RESULTS: Five papers met the inclusion criteria and were included. Three aspects of challenges at different levels emerged: infrastructure and institutional level factors, individual factors, and lack of contextually appropriate evidence. Three solutions were identified: capacity development opportunities, improving Internet access, and increasing awareness of free resources. CONCLUSION: This review provides an overview of common barriers medical and nursing professionals and students encounter whilst accessing scholarly literature in LMICs and identifies some possible solutions to address them. The findings can be used to guide institutions, as well as national and international decision makers to elicit policy which can promote the uptake of research in LMICs. Further research should focus on how these solutions could be harnessed to address the problems identified in this review.

Costs and clinical benefits of enhanced recovery after surgery (ERAS) in pancreaticoduodenectomy: an updated systematic review and meta-analysis.

PURPOSE: ERAS is a holistic and multidisciplinary pathway that incorporates various evidence-based interventions to accelerate recovery and improve clinical outcomes. However, evidence on cost benefit of ERAS in pancreaticoduodenectomy remains scarce. This review aimed to investigate cost benefit, compliance, and clinical benefits of ERAS in pancreaticoduodenectomy. METHODS: A comprehensive literature search was conducted on Medline, Embase, PubMed, CINAHL and the Cochrane library to identify studies conducted between 2000 and 2021, comparing effect of ERAS programmes and traditional care on hospital cost, length of stay (LOS), complications, delayed gastric emptying (DGE), readmission, reoperation, mortality, and compliance. RESULTS: The search yielded 3 RCTs and 28 cohort studies. Hospital costs were significantly reduced in the ERAS group (SMD = - 1.41; CL, - 2.05 to - 0.77; P < 0.00001). LOS was shortened by 3.15 days (MD = - 3.15; CI, - 3.94 to - 2.36; P < 0.00001) in the ERAS group. Fewer patients in the ERAS group had complications (RR = 0.83; CI, 0.76-0.91; P < 0.0001). Incidences of DGE significantly decreased in the ERAS group (RR = 0.72; CI, 0.55-0.94; P = 0.01). The number of deaths was fewer in the ERAS group (RR = 0.76; CI, 0.58-1.00; P = 0.05). CONCLUSION: This review demonstrated that ERAS is safe and feasible in pancreaticoduodenectomy, improves clinical outcome such as LOS, complications, DGE and mortality rates, without changing readmissions and reoperations, while delivering significant cost savings. Higher compliance is associated with better clinical outcomes, especially LOS and complications.

Understanding the use of telehealth in the context of the Family Nurse Partnership and other early years home visiting programmes: A rapid review.

Overview: This rapid review sought to understand the use of telehealth in early parenthood programmes sharing similarities with the Family Nurse Partnership. Methods: A rapid review protocol was developed in accordance with Cochrane Rapid Reviews Methods Guidance. Medline, Cochrane Library, and CINAHL databases were searched. Inclusion criteria were developed using population, intervention, comparator, outcome, study design, and timeframe components. Two reviewers searched, screened, and extracted data. AMSTAR was used for critical appraisal. Results were synthesised narratively. Results: Searches yielded 18 studies out of 881 for inclusion. Findings were identified across seven domains: acceptability and accessibility; therapeutic relationships; flexibility offered by telehealth; participation and engagement; confidentiality and privacy; equipment and technical considerations; and training and support. Conclusion: Telehealth provides unique opportunities to improve access to early years health services for young mothers. However, considerable accessibility barriers remain in the form of connectivity issues, access to appropriate technology, and the acceptability of remote healthcare delivery. This review presents a timely overview of the opportunities and challenges associated with the use of telehealth in early parenthood and family-based programmes.

Validity of Scottish predictors of child obesity (age 12) for risk screening in mid-childhood: a secondary analysis of prospective cohort study data-with sensitivity analyses for settings without various routinely collected predictor variables.

OBJECTIVE: To analyse the Growing Up in Scotland cohort for predictors of obesity at age 12, present at school entry (age 5-6). METHODS: The initial model included literature-based risk factors likely to be routinely collected in high-income countries (HICs), as well as "Adverse/Protective Childhood Experiences (ACEs/PCEs)". Missing data were handled by Multiple Chained Equations. Variable-reduction was performed using multivariable logistic regression with backwards and forwards stepwise elimination, followed by internal validation by bootstrapping. Optimal sensitivity/specificity cut-offs for the most parsimonious and accurate models in two situations (optimum available data, and routinely available data in Scotland) were examined for their referral burden, and Positive and Negative Predictive Values. RESULTS: Data for 2787 children with full outcome data (obesity prevalence 18.3% at age 12) were used to develop the models. The final "Optimum Data" model included six predictors of obesity: maternal body mass index, indoor smoking, equivalized income quintile, child's sex, child's BMI at age 5-6, and ACEs. After internal validation, the area under the receiver operating characteristic curve was 0.855 (95% CI 0.852-0.859). A cut-off based on Youden's J statistic for the Optimum Data model yielded a specificity of 77.6% and sensitivity of 76.3%. 37.0% of screened children were "Total Screen Positives" (and thus would constitute the "referral burden".) A "Scottish Data" model, without equivalized income quintile and ACEs as a predictor, and instead using Scottish Index of Multiple Deprivation quintile and "age at introduction of solid foods," was slightly less sensitive (76.2%) but slightly more specific (79.2%), leading to a smaller referral burden (30.8%). CONCLUSION: Universally collected, machine readable and linkable data at age 5-6 predict reasonably well children who will be obese by age 12. However, the Scottish treatment system is unable to cope with the resultant referral burden and other criteria for screening would have to be met.

Study protocol: a mixed-methods realist evaluation of the Universal Health Visiting Pathway in Scotland.

INTRODUCTION: The growing political emphasis on the early years reflects the importance of these formative years of life. Health visitors in the UK are uniquely positioned to improve health outcomes for children and families and to reduce health inequalities. Recently, there has been a policy change in Scotland in an attempt to enhance the delivery of the universal health visiting service. This study aims to examine the extent to which the enhanced Universal Health Visiting Pathway is implemented and delivered across Scotland and to assess any associated impacts. METHODS AND ANALYSIS: A mixed-methods study incorporating four methodological components and uses realist evaluation as the overall conceptual framework. It comprises three phases (1) initial programme theory development; (2) programme theory validation and (3) programme theory refinement. The programme theory validation will use interview and focus group data of parents and health visitors, and conduct a case note review at five study sites. It also involves a national survey of parents and health visitors and routine data analysis of existing secondary data. The analyses of the ensuing qualitative and quantitative data will be carried out using a convergent mixed-methods approach to ensure continuous triangulation of multiple data. The findings of the evaluation will provide contextually relevant understanding of how the Universal Health Visiting Pathway works and evidence the impact of increased investments in health visiting in Scotland. ETHICS AND DISSEMINATION: This protocol has been approved by the School of Health in Social Science Research Ethics Committee, University of Edinburgh. Additional approvals have been granted/will be sought from the Public Benefit and Privacy Panel for health and social care in Scotland for the case note review,survey and routine data analysis elements of the evaluation. The findings will be prepared as reports to the funders and presented at conferences. It will be submitted for publication in peer-reviewed journals.

Cohort study of high maternal body mass index and the risk of adverse pregnancy and delivery outcomes in Scotland.

OBJECTIVE: To examine the association between high maternal weight status and complications during pregnancy and delivery. SETTING: Scotland. PARTICIPANTS: Data from 132 899 first-time singleton deliveries in Scotland between 2008 and 2015 were used. Women with overweight and obesity were compared with women with normal weight. Associations between maternal body mass index and complications during pregnancy and delivery were evaluated. OUTCOME MEASURES: Gestational diabetes, gestational hypertension, pre-eclampsia, placenta praevia, placental abruption, induction of labour, elective and emergency caesarean sections, pre-term delivery, post-term delivery, low Apgar score, small for gestational age and large for gestational age. RESULTS: In the multivariable models controlling for potential confounders, we found that, compared with women with normal weight, the odds of the following outcomes were significantly increased for women with overweight and obesity (overweight adjusted ORs; 95% CI, followed by the same for women with obesity): gestational hypertension (1.61; 1.49 to 1.74), (2.48; 2.30 to 2.68); gestational diabetes (2.14; 1.86 to 2.46), (8.25; 7.33 to 9.30); pre-eclampsia (1.46; 1.32 to 1.63) (2.07; 1.87 to 2.29); labour induction (1.28; 1.23 to 1.33), (1.69; 1.62 to 1.76) and emergency caesarean section (1.82; 1.74 to 1.91), (3.14; 3.00 to 3.29). CONCLUSIONS: Women with overweight and obesity in Scotland are at greater odds of adverse pregnancy and delivery outcomes. The odds of these conditions increases with increasing body mass index. Health professionals should be empowered and trained to deliver promising dietary and lifestyle interventions to women at risk of overweight and obesity prior to conception, and control excessive weight gain in pregnancy.

The Daily Mile: teachers' perspectives of the barriers and facilitators to the delivery of a school-based physical activity intervention.

OBJECTIVES: Children spend a significant amount of their time in a school environment, often engaged in sedentary activities. The Daily Mile is a physical activity intervention which aims to increase physical activity and fitness in children through the completion of an outdoor teacher-led walk or run during the school day. This study aimed to explore the barriers, facilitators and perceived benefits of the Daily Mile from the perspectives of teachers through the use of qualitative semi-structured interviews. It also aimed to identify important context-specific factors, which might require consideration for those who intend to adopt the Daily Mile. SETTING: Eight Local Authority primary schools in the City of Edinburgh and East Lothian, UK. PARTICIPANTS: Thirteen teachers (eleven women) who teach children in primaries one to seven in a school which delivered the Daily Mile. RESULTS: Data were analysed using an interpretative thematic analysis. Teachers were positive and enthusiastic about the Daily Mile and perceived it to be beneficial to children's health and fitness. A number of barriers to participation were identified including inadequate all-weather running surfaces and time constraints in an already full school curriculum. The perceived impact on learning time was identified as a concern for teachers, while other benefits were also identified including increased teacher-child rapport and perceived enhanced classroom concentration levels. CONCLUSION: The Daily Mile appears to be a valuable addition to the school day, however important context-specific barriers to delivery of the Daily Mile exist, which should be considered when implementing the Daily Mile in schools.

Failures in reproductive health policy: overcoming the consequences and causes of inaction.

It is assumed that long-established research findings and internationally accepted evidence should, and will, be translated into policy and practice. Knowledge about what prevents harm and promotes health has, in fact, guided and resulted in numerous beneficial public health actions. However, such is not always the case. The authors examine three notable, and unwelcome, exceptions in the UK-all in the field of reproductive health and all focused on the period prior to pregnancy. The three examples of counterproductive inaction discussed are: fortifying flour with Vitamin B9 (folic acid); preventing foetal alcohol spectrum disorders; and reducing risks and better regulating a highly teratogenic medication (valproate). The adverse consequences, as well as the causes, of inaction are analysed for each example. Reasons for optimism, and recommendations for overcoming inaction, are also offered, in particular, greater priority should be accorded to preconception health, education and care.

Credibility of subgroup analyses by socioeconomic status in public health intervention evaluations: An underappreciated problem?

There is increasing interest amongst researchers and policy makers in identifying the effect of public health interventions on health inequalities by socioeconomic status (SES). This issue is typically addressed in evaluation studies through subgroup analyses, where researchers test whether the effect of an intervention differs according to the socioeconomic status of participants. The credibility of such analyses is therefore crucial when making judgements about how an intervention is likely to affect health inequalities, although this issue appears to be rarely considered within public health. The aim of this study was therefore to assess the credibility of subgroup analyses in published evaluations of public health interventions. An established set of 10 credibility criteria for subgroup analyses was applied to a purposively sampled set of 21 evaluation studies, the majority of which focussed on healthy eating interventions, which reported differential intervention effects by SES. While the majority of these studies were found to be otherwise of relatively high quality methodologically, only 8 of the 21 studies met at least 6 of the 10 credibility criteria for subgroup analysis. These findings suggest that the credibility of subgroup analyses conducted within evaluations of public health interventions' impact on health inequalities may be an underappreciated problem.

Supporting the health and well-being of school-aged children through a school nurse programme: a realist evaluation.

BACKGROUND: The school nurse's role varies across countries. In Scotland, the Chief Nursing Officer recommended that the role should be refocused. The refocused programme emphasises nine care pathways with a view to improve pupils' health and wellbeing. Two sites were identified to test this new programme. Our aim was to assess how, for whom and under what circumstances the programme works in order to provide learning to support school nurse training and intended national roll-out. METHODS: This study was a mixed methods study, using a realist evaluation approach, and conducted in three phases. In phase one, six nurse managers from both study sites took part in individual interviews or focus groups and this was complemented by programme documents to develop initial programme theory. In phase two, the programme theory was tested using qualitative data from 27 school nurses, and quantitative data from the first 6 months of the programme that captured patterns of referral. The programme theory was refined through analyses and interpretation of data in phase three. RESULTS: The findings show that the programme enhanced opportunities for early and improved identification of health and wellbeing needs. The context of the nine pathways worked through the mechanism of streamlining referral of relevant cases to school nurses, and yielded positive outcomes by extending school nurses and thus children's engagement with wider services. The mental health and wellbeing pathway was the most frequently used, and nurses referred complex mental health cases to more specialist mental health services, but felt less equipped to deal with low to moderate cases. CONCLUSIONS: The programme facilitated early identification of risk but was less successful at equipping school nurses to actually deliver specific interventions as intended. Capacity building strategies for school nurses should seek to enhance intervention delivery skills within the parameters of the pathways. Realist evaluation provided a useful framework in terms of identifying contextual and mechanistic influences that required strengthening prior to wider implementation.

Adolescents and health-related behaviour: using a framework to develop interventions to support positive behaviours.

BACKGROUND: Experimentation is a natural part of adolescent maturation. In conjunction with increased exposure to behaviours such as alcohol or substance use, and the potentially intensified influence of peer groups, unhealthy behaviour patterns may develop as part of this experimentation. However, the adolescent years also provide considerable opportunity for behaviour to be shaped in positive ways that may improve immediate and longer term health outcomes. A systematic review carried out by the authors concluded that physiological changes during adolescence need to be considered when designing or implementing interventions, due to their influence on health behaviours. The aim of the study is to demonstrate how the six steps in quality intervention development (6SQuID) framework can be used, in conjunction with research or review findings, to inform the development of pilot or feasibility studies. Using the synthesised findings from our adolescent systematic review, we sought to illustrate how adolescent interventions might be designed to target specific health behaviours and augment positive adolescent health outcomes. METHODS: We applied the 6SQuID framework to the findings from a review of adolescent physiological influences on health behaviour. This involved following the process defined within 6SQuID and applying the sequential steps to build a proposed pilot study, based on the pre-defined findings of our systematic review. We used the Social Learning Theory to assist in identifying how and why change can be influenced, with and for adolescents. RESULTS: We devised a pilot study example, targeting teaching assistants, to illustrate how the detailed steps within the 6SQuID framework can assist the development and subsequent implementation of adolescent interventions that are likely to be effective. CONCLUSIONS: This paper gives details of how the 6SQuID framework can be used for intervention development, using specific research findings, across a variety of adolescent health behaviours. This example provides details of how to operationalise 6SQuID in practical terms that are transferrable to other populations and situations. In this respect, we anticipate that this illustrative case may be of use in the design, development, and implementation of a wide variety of interventions.

Realist evaluation of an enhanced health visiting programme.

BACKGROUND: The health visitors' role in many countries is changing. In Scotland, the role has undergone substantial changes through the introduction of an enhanced health visiting programme, which includes increased, structured home visits. This evaluation was conducted within NHS Ayrshire and Arran, one of the 14 Scottish Health Boards. Our aim was to understand and explain how, and why, the programme could contribute to improving health and wellbeing outcomes for children and families. METHODS: We used a realist evaluation approach, conducted in three phases. In phase one, eight managerial staff involved in developing and implementing the programme provided data, which were used to develop initial programme theories. In phase two, the programme theories were tested using qualitative data from 25 health visitors and 22 parents. The programme theories were refined through analyses and interpretation of data in phase three. RESULTS: The home visiting context provided by the programme interacted with the mechanisms of the programme and produced outcomes such as early identification of health and wellbeing issues amongst families who needed more support, leading to referral and engagement with sources of additional help. The home visits facilitated development of parent-health visitor relationships, and parents considered health visitors as their first point of contact on children's wellbeing and developmental-related issues. Moreover, the programme provided more clarity to health visitors' role, which in turn enhanced partnership working. However, there were aspects of the programme that may require further development. For instance, both parents and health visitors were concerned about the wide gaps between some home visits. CONCLUSIONS: The enhanced health visiting programme increased opportunities for monitoring and early identification of health and wellbeing concerns. It created structures for a more efficient partnership working and ensured that the needs of children and families were supported. These benefits need to be evaluated further in an effectiveness study.

How has child growth around adiposity rebound altered in Scotland since 1990 and what are the risk factors for weight gain using the Growing Up in Scotland birth cohort 1?

BACKGROUND: Adiposity rebound is considered critical to the development of overweight and obesity. The purpose of this study was to investigate how growth has changed in comparison to the UK 1990 BMI growth reference curves between the ages 4-8 years and identify any marked deviations in growth. We also examined potential maternal and child risk/protective factors associated with the altered growth patterns. METHODS: We used data from birth cohort 1 of the Growing Up in Scotland study. Height and weight data (N = 2 857) were available when the children were aged approximately 4 (sweep 4), 6 (sweep 6) and 8 years (sweep 7). For each child, percentile change per month was calculated to identify deviations from the UK 1990 growth patterns. Marked changes (>10 % annual change) in percentiles or weight category between each sweep for each child were considered as reflecting a decreasing (leptogenic), increasing (obesogenic) or no change pattern. Logistic regression was used to explore which maternal or child risk factors were associated with belonging to the different growth patterns. RESULTS: Sixty six percent (66 %) of the cohort did not show marked changes in BMI percentile and growth compared to the UK 1990 reference population. However, the median BMI percentile of this group was around the 70th. The most common deviation in BMI percentile was early decrease (11.5 %). In terms of weight categories, contemporary maternal obesity (odd ratio (OR) =2.89; 95 % confidence interval (CI) 2.09, 3.98) and mother smoking during pregnancy (OR =1.56; 95 % CI 1.13, 2.15) were found to be significantly associated with increased odds of obesogenic growth trajectory relative to no change trajectory. Breastfeeding (OR = 1.18; 95 % CI 0.88, 1.57) was also associated with increased odds of obesogenic growth but this was not significant in the adjusted model. CONCLUSIONS: This study has shown that there is a substantial shift in the general population distribution of BMI since 1990. We identified maternal weight status as the strongest obesogenic factor and this is an indication that more innovative obesity preventive strategies should also consider intergenerational approaches.

Six steps in quality intervention development (6SQuID).

Improving the effectiveness of public health interventions relies as much on the attention paid to their design and feasibility as to their evaluation. Yet, compared to the vast literature on how to evaluate interventions, there is little to guide researchers or practitioners on how best to develop such interventions in practical, logical, evidence based ways to maximise likely effectiveness. Existing models for the development of public health interventions tend to have a strong social-psychological, individual behaviour change orientation and some take years to implement. This paper presents a pragmatic guide to six essential Steps for Quality Intervention Development (6SQuID). The focus is on public health interventions but the model should have wider applicability. Once a problem has been identified as needing intervention, the process of designing an intervention can be broken down into six crucial steps: (1) defining and understanding the problem and its causes; (2) identifying which causal or contextual factors are modifiable: which have the greatest scope for change and who would benefit most; (3) deciding on the mechanisms of change; (4) clarifying how these will be delivered; (5) testing and adapting the intervention; and (6) collecting sufficient evidence of effectiveness to proceed to a rigorous evaluation. If each of these steps is carefully addressed, better use will be made of scarce public resources by avoiding the costly evaluation, or implementation, of unpromising interventions.

A realist evaluation of an antenatal programme to change drinking behaviour of pregnant women.

OBJECTIVE: to use realist evaluation to describe and explain how and in what circumstances screening and alcohol brief interventions work in routine antenatal care. DESIGN: a realist evaluation incorporating systematic reviews and qualitative data. SETTING: NHS Lothian, which is one of the 14 Scottish health boards. PARTICIPANTS: participants were recruited from two maternity units. In phase one, interviews were conducted with four participants responsible for policy implementation. These data were supported by two systematic reviews. In phase two, 17 pregnant women and 15 midwives participated in interviews, with a further six midwifery team leaders involved in a focus group. FINDINGS: training and resources provided to midwives as part of the programme acted as facilitating mechanisms that improved their skills and confidence to screen and deliver alcohol brief interventions. The programme elicited positive change in attitudes to drinking in pregnancy and possibly stimulated drinking behaviour change amongst pregnant women. However, the small numbers of pregnant women being identified for alcohol brief interventions meant delivery was infrequent and resulted in the programme not working as anticipated. The findings also revealed contextual issues around midwife-pregnant woman relationship and the challenges of negotiating the timing of screening and alcohol brief interventions delivery. CONCLUSIONS: Drinking in pregnancy is an emotive issue, therefore delivering alcohol brief interventions at the first antenatal appointment when they are more likely to achieve the most benefits poses challenges. When training midwives to screen and deliver alcohol brief interventions, special attention is needed to improve person-centred communication skills to overcome barriers associated with discussing sensitive prenatal alcohol use and enhance early identification and delivery of alcohol brief interventions at the first antenatal appointment.

Alcohol brief interventions in Scottish antenatal care: a qualitative study of midwives' attitudes and practices.

BACKGROUND: Infants exposed to alcohol in the womb are at increased risk of experiencing health problems. However, mixed messages about the consequences of prenatal alcohol consumption have resulted in inconsistent attitudes and practices amongst some healthcare practitioners. Screening and alcohol brief interventions (ABIs) can reduce risky drinking in various clinical settings. Recently, a program of screening and ABIs have been implemented in antenatal care settings in Scotland. However, current evidence suggests that midwives' involvement in alcohol brief interventions activities is patchy. This study explored midwives' attitudes and practices regarding alcohol screening and ABIs in order to understand why they are relatively underutilized in antenatal care settings compared to other clinical settings. METHODS: This was a qualitative study, involving semi-structured interviews with 15 midwives and a focus group with a further six midwifery team leaders (21 participants in total) in Scotland. Interview transcripts were analysed using thematic analysis. RESULTS: Midwives were positive about their involvement in the screening and ABI program. However, they were not completely convinced about the purpose and value of the screening and ABIs in antenatal care. In the midst of competing priorities, the program was seen as having a low priority in their workload. Midwives felt that the rapport between them and pregnant women was not sufficiently established at the first antenatal appointment to allow them to discuss alcohol issues appropriately. They reported that many women had already given up drinking or were drinking minimal amounts prior to the first antenatal appointment. CONCLUSIONS: Midwives recognised the important role they could play in alcohol intervention activities in antenatal care. As the majority of women stop consuming alcohol in pregnancy, many will not need an ABI. Those who have not stopped are likely to need an ABI, but midwives were concerned that it was this group that they were most likely to alienate by discussing such concerns. Further consideration should be given to pre-pregnancy preventative measures as they are more likely to reduce alcohol-exposed pregnancies.
