Perceptions of antibiotic resistance among hospital healthcare professionals in high-income countries: A systematic review of causes, consequences, and solutions

OBJECTIVE

Antibiotic resistance (ABR) is a major threat to public health. Hospital healthcare professionals are important stakeholders in curbing ABR. To be able to encourage healthcare professionals to act against ABR, information on their perceptions is needed. Yet, summary evidence on how healthcare professionals perceive ABR causes, consequences, and solutions is outdated. This review aims to elucidate these perceptions.

METHODS

We searched MEDLINE, EMBASE, PsycINFO, and CINAHL for literature published until July 6th, 2022, and used Web of Science and Scopus to identify reports citing included studies. Reports of quantitative original research from high-income countries were included if they investigated hospital healthcare professionals' perceptions about ABR. Descriptive data and data on perceptions about causes, consequences, and solutions regarding ABR were extracted. PROSPERO registration: CRD42022359249.

RESULTS

The database search and citation tracking yielded 13,551 and 694 papers respectively. Forty-eight reports from 46 studies were included in the review. These studies were performed between 1999 and 2023 and included between 8 and 1362 participants. Healthcare professionals perceived ABR as a problem that is more severe nationally than locally and they primarily recognize ABR as a distant and abstract problem. Studies mostly concurred on prescribing behavior as a cause and a solution for ABR, while external causes and solutions (e.g., in agriculture) elicited less agreement.

CONCLUSIONS

Studies with a primary focus on the perceptions of healthcare professionals about ABR are limited. Healthcare professionals perceive prescribing behavior as a major cause of ABR and a focus area for ABR solutions.

Barriers and facilitators of implementation of new antibacterial technologies in patient care: an interview study with orthopedic healthcare professionals at a university hospital

BACKGROUND

Antimicrobial resistance is a major global health threat. Therefore, promising new antibacterial technologies that could minimize our dependence on antibiotics should be widely adopted. This study aims to identify the barriers and facilitators of the adoption of new antibacterial technologies in hospital patient care.

METHODS

Semi-structured interviews, based on the Consolidated Framework for Implementation Research, were conducted with healthcare professionals related to the orthopedics department of an academic hospital in The Netherlands.

RESULTS

In total, 11 healthcare professionals were interviewed. Scientific evidence for the effectiveness of the technology was the most explicitly mentioned facilitator of adoption, but other (often contextual) factors were also considered to be important. At the level of the inner and outer setting, high costs and lacking coverage, competition from other firms, and problems with ordering and availability were the most explicit perceived barriers to adoption. Participants did not collectively feel the need for new antibacterial technologies.

CONCLUSIONS

Barriers and facilitators of the adoption of new antibacterial technologies were identified related to the technology, the hospital, and external factors. The implementation climate might have an indirect influence on adoption. New antibacterial technologies that are scientifically proven effective, affordable, and easily obtainable will most likely be adopted.

Outcomes of the combined lifestyle intervention CooL during COVID-19: a descriptive case series study

BACKGROUND

The main objective of this nationwide study was to investigate changes in outcomes between baseline and eight months of participation regarding anthropometrics, control and support, physical activity, diet attentiveness, perceived fitness, sleep, and stress of participants in Coaching on Lifestyle (CooL), a Combined Lifestyle Intervention (CLI). Since the study took place when the COVID-19 pandemic emerged, we defined a subobjective, i.e., to address changes in intervention outcomes over time while participants were exposed to pandemic-related restrictions and uncertainties.

METHODS

Data were collected from November 2018 until October 2021 at different locations across the Netherlands from 1824 participating adults, meeting the CLI inclusion criteria. We collected a broad set of data on anthropometrics (weight, body mass index (BMI), waist circumference), control and support (self-mastery, social support), physical activity (sedentary time on least/most active days, physical active minutes), diet attentiveness (attentiveness to meal composition, awareness to amounts of food and attentiveness to consuming), alcohol consumption, smoking, perceived fitness (perceived health, fitness when waking, fitness during daytime, impact daily stress), sleep and stress.

RESULTS

All outcomes showed improvements after eight months compared to baseline except for social support and smoking. Large effect sizes were found on weight (0.57), waist circumference (0.50) and perceived health (0.50). Behaviour patterns showed small to large effect sizes, with the largest effect sizes on diet attentiveness (i.e., attentiveness to meal composition (0.43), awareness to amounts of food (0.58) and attentiveness to consuming (0.39)). The outcomes of participants pre COVID-19 versus during COVID-19 showed differences on self-mastery (p = 0.01), sedentary time (all underlying constructs p < 0.02), perceived fitness (all underlying constructs p < 0.02) and stress (p < 0.01).

CONCLUSION

The results show that small changes in multiple behaviours go along with a large positive change in perceived health and health-related outcomes in line with the lifestyle coaching principles. In addition, participating in CooL may have protected against engaging in unhealthier behaviour during the pandemic.

TRIAL REGISTRATION

As the CLI is considered usual health care that does not fall within the scope of the Dutch Medical Research Involving Human Subjects Act, this study was exempt from trial registration.

Is the transition from primary to secondary school a risk factor for energy balance-related behaviours? A systematic review

OBJECTIVE

The substantial changes in the physical and social environment during the transition from primary to secondary school may significantly impact adolescents' energy balance-related behaviours (i.e. dietary behaviour, sedentary behaviour, sleep behaviour and physical activity (PA)). This is the first review systematically summarising evidence on changes in four energy balance-related behaviours of adolescents across the school transition from primary to secondary school.

DESIGN

For this systematic review, the electronic databases Embase, PsycINFO and SPORTDiscus were searched for relevant studies from inception to August 2021. PubMed was searched for relevant studies from inception to September 2022. Inclusion criteria were: (i) longitudinal studies reporting; (ii) one or more energy balance-related behaviours; and (iii) across the school transition, that is, with measurement(s) during both primary and secondary school.

SETTING

Transition from primary to secondary school.

PARTICIPANTS

Adolescents across the transition from primary to secondary school.

RESULTS

Thirty-four studies were eligible. We found strong evidence for an increase in sedentary time, moderate evidence for a decrease in fruit and vegetable consumption, and inconclusive evidence for a change in total, light, and moderate-to-vigorous PA, active transport, screen time, unhealthy snack consumption, and sugar-sweetened beverages consumption among adolescents across the school transition.

CONCLUSIONS

During the transition from primary to secondary school, sedentary time and fruit and vegetable consumption tend to change unfavourably. More high-quality, longitudinal research is needed specifically on changes in energy balance-related behaviour across the school transition, especially regarding sleep behaviour.

Effects of timed and targeted counselling by community health workers on maternal and household practices, and pregnancy and newborn outcomes in rural Uganda

INTRODUCTION

Pregnancy and birth-related complications claim the lives of millions of women and newborns every year. Improving their survival chances remains an urgent global challenge, including in Uganda. Community health workers (CHWs) play a crucial role in bridging the gap between the community and the official health system in Uganda. Timed and targeted Counselling (ttC) is an individual-level behavioral change communication method used by CHWs, aimed at pregnant women and caregivers of children under the age of two.

AIM

This study examined whether the implementation of the ttC intervention by the CHWs was associated with improved household practices and outcomes during the pregnancy and newborn period.

METHODS

A multi-stage sampling technique was employed with a total of 749 participants in the intervention group (ttC intervention), and 744 participants in the control group (no ttC). Data on quality of maternal and household antenatal care (ANC) and essential newborn care (ENC) practices, as well as on pregnancy and newborn outcomes were collected through questionnaires from May 2018 to May 2020. McNemar's Chi-square tests were used to compare outcomes before and after implementation, and between the intervention and control group.

RESULTS

Results showed that, compared to baseline, ttC contributed significantly to the demand for quality of service during ANC, ENC and partner involvement in maternal and newborn health. In comparison to the control group, the ttC group showed significantly higher early ANC attendance rates and higher quality of ANC and ENC.

CONCLUSION

ttC is a comprehensive, goal-driven approach that seems to contribute to the improvement of quality of maternal and household practices, and pregnancy and newborn outcomes in Uganda.

Supporting schools during the implementation of the health-promoting school approach: The roles of a healthy school advisor

Introduction

The health-promoting school (HPS) approach was developed by the World Health Organization to create health promotion changes in the whole school system. Implementing the approach can be challenging for schools because schools are dynamic organizations with each a unique context. Many countries worldwide have a health promotion system in place in which healthy school (HS) advisors support schools in the process of implementing the HPS approach. Even though these HS advisors can take on various roles to provide support in an adaptive and context-oriented manner, these roles have not yet been described. The current study aims to identify and describe the key roles of the HS advisor when supporting schools during the dynamic process of implementing the HPS approach.

Methods

The study was part of a project in which a capacity-building module was developed for and with HS advisors in the Netherlands. In the current study, a co-creation process enabled by participatory research was used in which researchers, HS advisors, national representatives, and coordinators of the Dutch HS program participated. Co-creation processes took place between October 2020 and November 2021 and consisted of four phases: (1) a narrative review of the literature, (2) interviews, (3) focus groups, and (4) a final check.

Results

Five roles were identified. The role of "navigator" as a more central one and four other roles: "linking pin," "expert in the field," "critical friend," and "ambassador of the HPS approach." The (final) description of the five roles was recognizable for the HS advisors that participated in the study, and they indicated that it provided a comprehensive overview of the work of an HS advisor in the Netherlands.

Discussion

The roles can provide guidance to all Dutch HS advisors and the regional public health organizations that employ them on what is needed to provide sufficient and context-oriented support to schools. These roles can inspire and guide people from other countries to adapt the roles to their own national context.

Impact of malaria control interventions on malaria infection and anaemia in low malaria transmission settings: a cross-sectional population-based study in Sudan

BACKGROUND

The past two decades were associated with innovation and strengthening of malaria control interventions, which have been increasingly adopted at large scale. Impact evaluations of these interventions were mostly performed in moderate or high malaria transmission areas. This study aimed to evaluate the use and performance of malaria interventions in low transmission areas on malaria infections and anaemia.

METHODS

Data from the 2016 Sudan malaria indicator survey was used. Multi-level logistic regression analysis was used to assess the strength of association between real-life community-level utilization of malaria interventions [diagnosis, artemisinin-based combination therapies (ACTs) and long-lasting insecticidal nets (LLINs)] and the study outcomes: malaria infections and anaemia (both overall and moderate-to-severe anaemia).

RESULTS

The study analysis involved 26,469 individuals over 242 clusters. Malaria infection rate was 7.6%, overall anaemia prevalence was 47.5% and moderate-to-severe anaemia prevalence was 4.5%. The average community-level utilization was 31.5% for malaria diagnosis, 29.9% for ACTs and 35.7% for LLINs. The odds of malaria infection was significantly reduced by 14% for each 10% increase in the utilization of malaria diagnosis (adjusted odds ratio (aOR) per 10% utilization 0.86, 95% CI 0.78-0.95, p = 0.004). However, the odds of infection was positively associated with the utilization of LLINs at community-level (aOR per 10% utilization 1.20, 95% CI 1.11-1.29, p < 0.001). No association between malaria infection and utilization of ACTs was identified (aOR per 10% utilization 0.97, 95% CI 0.91-1.04, p = 0.413). None of the interventions was associated with overall anaemia nor moderate-to-severe anaemia.

CONCLUSION

There was strong evidence that utilization of malaria diagnosis at the community level was highly protective against malaria infection. No protective effect was seen for community utilization of ACTs or LLINs. No association was established between any of the interventions and overall anaemia or moderate-to-severe anaemia. This lack of effectiveness could be due to the low utilization of interventions or the low level of malaria transmission in the study area. Identification and response to barriers of access and low utilization of malaria interventions are crucial. It is crucial to ensure that every suspected malaria case is tested in a timely way, notably in low transmission settings.

Determinants of natural adult sleep: An umbrella review

BACKGROUND

Sleep has a major impact on health, which makes it a relevant topic for research and health practitioners. Research on sleep determinants, i.e. factors that positively or negatively influence sleep, is fragmented.

OBJECTIVE

The purpose of this umbrella review is to provide an overview of the current evidence on determinants of natural adult sleep.

METHODS

A comprehensive literature search was performed on determinants of sleep. Reviews and meta-analyses on natural adult sleep were included. Six electronic databases (PubMed, WoS, Embase, CINAHL, PsycInfo and Cochrane) were used for the search, last accessed September 2021. The quality of the selected articles was assessed using the AMSTAR2 tool. Results were categorized in four main categories: biological, behavioral, environmental and personal/socio-economical determinants.

RESULTS

In total 93 reviews and meta-analyses resulted in a total of 30 identified determinants. The impact of each determinant differs per individual and per situation. Each determinant was found to affect different sleep parameters and the relationship with sleep is influenced by both generic and specific moderators.

DISCUSSION

A comprehensive overview on relevant sleep determinants provides a practical and scientifically based starting point to identify relevant intervention approaches to secure or improve individual sleep quality. The difference in aggregation level of the determinants and in measurement methods are the major limitations of this umbrella review. Extending existing generic sleep hygiene rules with an overview of all types of potential determinants will enhance the awareness of the complexity and can be used to improve the effect of sleep interventions in health promotion.

TRIAL REGISTRATION

The umbrella review was registered with PROSPERO (registration ID CRD42020149648) https://www.google.com/search?client=firefox-b-d&q=CRD42020149648.

Exploring the implementation dynamics of the Health Promoting School approach in Europe: a qualitative study among school health representatives

Purpose

Adapting the Health Promotion School (HPS) approach to context specifics is acknowledged as being essential for implementation and achieving optimal effectiveness. This study aims to explore implementation variations on seven HPS spectra (such as top-down to bottom-up involvement of stakeholders) on which implementation of the HPS approach can vary, and the factors that relate to navigation on these spectra.

Design/methodology/approach

In 2020, fourteen HPS researchers and professionals from ten European countries participated in semi-structured interviews.

Findings

Navigation variations on the HPS spectra occurred throughout most spectra. Further, a tendency was found towards spectrum extremes of addressing multiple core-components, implementing non-disruptive Health Promotion (HP) programmes, and evaluating the HPS approach through an action-oriented research approach. Important general factors were resources, staff capacity and time available to staff members for implementing the HPS approach. Some spectra required more specific factors like organisational skills, leadership or a certain level of democracy.

Practical implications

The implementation of the HPS approach should be supported by implementation strategies addressing the spectrum-specific factors, but more generic factors such as staff capacity, resources and the level of democracy should also be considered.

Originality/value

This study explores navigation variations throughout HPS spectra rather than the HPS approach in general. It also nuances implementation diversity across and within different European contexts.

As Steady as a Rock! Gaining Insight in Recruitment and Retention Among Primary School Children With Behavioural Problems in Sport Mix Club

The number of children dealing with behavioural problems is increasing. A major challenge in many health-supportive programmes is the recruitment and retention of these children. In the current study, Sport Mix Club (SMC), an approach to enhance socioemotional disorders of 4- to 12-year-old children through sport classes in municipality Vaals, the Netherlands, is used as an illustration. Where many studies faced difficulties getting and keeping children in their interventions, SMC overcame this challenge. Therefore, we decided to explore "What factors contribute to enhanced recruitment and retention procedures among children with behavioural problems in Sport Mix Club?" A qualitative case study design using the analysis of the administrative logbook of the SMC coach and trainees, individual interviews with the SMC coach, trainees (n = 2), school teachers (n = 3) and parents of participating children (n = 9), and four focus group interviews with children (n = 13) were carried out. During the recruitment and retention of SMC, the human psychological need of relatedness seemed to be of crucial value. The fact that the SMC coach: (1) made efforts to become a familiar face for children, parents and community partners beforehand; (2) showed enthusiasm; and (3) placed her focus on having fun as opposed to the children's problems, seemed to be decisive in the process of getting children to participate in SMC and retaining their participation.

Impact of malaria control interventions on malaria infection and anaemia in areas with irrigated schemes: a cross-sectional population-based study in Sudan

Background

While the overall burden of malaria is still high, the global technical strategy for malaria advocates for two sets of interventions: vector control-based prevention and diagnosis and prompt effective treatment of malaria cases. This study aimed to assess the performance of malaria interventions on malaria infection and anaemia in irrigated areas in Sudan.

Methods

Based on the Sudan 2016 national malaria indicator survey, data for two states (Gezira and Sennar), characterized by large-irrigated schemes, were analysed. Four community-level malaria interventions were used as contextual variables: utilization of malaria diagnosis, utilization of Artemisinin-based combination therapy (ACT), utilization of long-lasting insecticidal nets (LLINs) and coverage with indoor residual spraying (IRS). Association between these interventions and two outcomes: malaria infection and anaemia, was assessed separately. Malaria infection was assessed in all age groups while anaemia was assessed in children under 5 years. Multilevel multiple logistic regression analysis were conducted.

Results

Among 4478 individuals involved in this study distributed over 47 clusters, the overall malaria infection rate was 3.0% and 56.5% of the children under 5 years (total = 322) were anaemic. Except for IRS coverage (69.6%), the average utilization of interventions was relatively low: 52.3% for utilization of diagnosis, 33.0% for utilization of ACTs and 18.6% for LLINs utilization. The multi-level multiple logistic regression model showed that only IRS coverage was associated with malaria infection (Odds ratio 0.83 per 10% coverage, 95%Confidence Interval (95%CI) 0.74–0.94, p = 0.003) indicating that a higher level of IRS coverage was associated with less malaria infection. Anaemia was not associated with any intervention (all p values larger than 0.1).

Conclusions

Malaria transmission in Gezira and Sennar areas is low. IRS, with insecticide to which vectors are susceptible, is an effective malaria control intervention in irrigated schemes. Community utilization of other interventions was not associated with malaria infection in this study. This may be due to the low utilization of these interventions. However, individual use of LLINs provide personal protection. This study failed to establish an association between anaemia and malaria control interventions in low transmission areas. The higher level of malaria infection in urban areas is a cause for concern.

Changing the preschool setting to promote healthy energy balance-related behaviours of preschoolers: a qualitative and quantitative process evaluation of the SuperFIT approach

Background

The Early Care and Education (ECE) setting plays an important role in the promotion of a healthy lifestyle in young children. SuperFIT is a comprehensive, integrated intervention approach designed to promote healthy energy balance-related behaviours in preschoolers. Insight in the process of implementation and the context in which SuperFIT was implemented supports the understanding of how the intervention works in practice. This process evaluation examined factors that influenced the implementation and maintenance, as well as the (perceived) changes in the ECE setting.

Methods

A mixed-methods study was conducted. SuperFIT was implemented at twelve preschools in the south of the Netherlands. The process evaluation was performed among preschool teachers, managers of the preschool organisation, and implementers. Semi-structured in-depth (group) interviews, quantitative process questionnaires, the Child-care Food and Activity Practices Questionnaire (CFAPQ) and the Environmental and Policy Assessment and Observation (EPAO) were used to evaluate the implementation and maintenance of SuperFIT and the changes in the preschool setting. The interviews were analysed using a theoretical framework based on the Implementation Framework of Fleuren and Damschröder’s Consolidated Framework for Implementation Research. Descriptive analyses were performed on the quantitative data.

Results

Various intervention activities were implemented in the preschool setting. Although the intention to maintain SuperFIT was present, this was hindered by time constraints and lack of financial resources. Important factors that influenced implementation and maintenance were incongruence with current practice, limited perceived capabilities to integrate SuperFIT in daily practice, group composition at the preschools, and the perceived top-down implementation. Organizational vision and societal attention regarding healthy behaviour in general were perceived to be supportive for implementation and maintenance. Predominantly, favourable changes were seen in the nutrition- and physical activity-related practices of preschool teachers and other aspects of the social preschool environment such as the use of play materials. Limited changes were observed in the physical preschool environment.

Conclusions

Several factors influenced the implementation and maintenance of SuperFIT in the preschool setting. Some factors evolved over time from hindering to facilitating, emphasising the importance of allowing sufficient time for intervention implementation. SuperFIT changed mainly the social preschool environment.

HealthyLIFE, a Combined Lifestyle Intervention for Overweight and Obese Adults: A Descriptive Case Series Study

(1) Background: The aim of this study is to investigate changes over time in participants of healthyLIFE, a Combined Lifestyle Intervention (CLI) based on the Coaching on Lifestyle (CooL) intervention. This study focuses on changes in behavior, physical fitness, motivation and Positive Health eight months after the start of the intervention. (2) Methods: In total, 602 Dutch adults, meeting the CLI inclusion criteria, were included from January 2018 until October 2020 in this descriptive case series study. We collected a broad set of data regarding weight/BMI, physical fitness, motivation, self-efficacy, social influence, personal barriers and needs towards food and physical activity and perceived personal health by means of the six dimensions of Positive Health. (3) Results: Eight months after baseline, positive effects of the intervention were found on most outcome measures. We found an increase in all measured aspects of physical fitness (stamina, flexibility, mobility, hand grip strength and BMI). Dietary changes were limited during the healthyLIFE intervention, except for fruit consumption (increase with an effect size of 0.42). The largest effect sizes were found for the dimensions of Positive Health ranging from 0.41 to 0.68. (4) Conclusion: The healthyLIFE intervention is successful in improving participants’ BMI, physical fitness, and perceived physical, mental and social health. A broad health perspective, beyond physical measurements, is recommended when studying effects of the CLI.

Determinants of Weight-Related Behaviors in Male Saudi University Students: A Qualitative Approach Using Focus Group Discussions

Obesity is a serious public health concern in the Gulf States. Students are exposed to many unhealthy weight-related behaviors due to college life. However, research that gives insight into regional and culture-specific aspects and determinants of weight-related behaviors in students is lacking. The purpose of this study was to explore the potential determinants of weight change, eating behaviors, physical activity, sedentary behaviors, and sleep behaviors in Saudi university students. Five semi-structured focus group discussions guided by Social Cognitive Theory were conducted, consisting of 33 male university students 20 to 22 years old. The data were transcribed, coded, and organized according to themes. The students reported weight gain due to personal, social, and environmental factors related to university lifestyle, such as unhealthy eating behaviors, low physical activity, high sedentary behaviors, and inadequate sleep. Both eating behaviors and physical activity shared similar personal aspects found in other studies, such as knowledge, stress, lack of time, and lack of motivation. However, there were some unique social and environmental factors in the region, such as the social norms, cultural aspects, weather conditions, passive transport dependency, and khat consumption, compared with studies worldwide. Such differences are key factors to developing effective interventions in the future.

[Effects and costs of The Healthy Primary School of the Future]

OBJECTIVE

To study school lifestyle interventions for elementary school children (The Healthy Primary School of the Future).

RESEARCH QUESTION

What are the effects of the introduction of increased physical activity with or without healthy nutrition on health behaviour and BMI of young children and what are the costs of this program?

DESIGN

Prospective controlled non-randomized study with nearly 1700 children in Parkstad (South-East Netherlands).

RESULTS

Preliminary results after two years show that the combination of increased physical activity and healthy nutrition result in a decreased BMIz-score (-0.036), increased physical activity alone in hardly any change (-0.10) while in the control group the BMIz-score increased (0.052). The net societal costs of the combination of physical activity and health nutrition costs were 1 euro per child per day.

CONCLUSION

The study contributes to the increasing amount of evidence proving that lifestyle interventions are effective in reducing the obesity epidemic. Future studies will show whether a weight reduction in children will result in the prevention of chronic disease later on in life and what the cost reduction related to this result will be.

Anaemia prevalence and determinants in under 5 years children: findings of a cross-sectional population-based study in Sudan

Background

Early childhood is an age at risk of anaemia and its deleterious consequences. In Sudan, there is limited evidence on the prevalence and determinant of anaemia in under-five children. This study was conducted in Sudan to assess the prevalence of anaemia in children and to identify its determinants.

Methods

We conducted a household survey involving children aged 6 months to 5 years in November 2016. A representative population was sampled across rural, urban and camps settlements across 18 states in Sudan. We used a pre-designed questionnaire data collection. Haemoglobin (Hb) level and malaria infection were checked. In this cross-sectional study, we dichotomized the outcome variable and performed logistic regression analyses.

Results

A total of 3094 children under 5 years enrolled in the study, 1566 (50.6%) of them were female and 690 (22.3%) of them were under 2 years old. Anaemia prevalence in the whole cohort (6 months - < 5 years) was 49.4% and the mean haemoglobin concentration was 108.1 (standard deviation (SD): 15.4) g/L. The prevalence in younger (6 months - < 2 years) children (61.9%) was higher than in older (2 - < 5 years) children (45.6%) (p < 0.001). Severe anaemia (Hb < 70 g/L) prevalence in the whole population was 1.6%. Age (Odds ratio (OR) 2.25, 95% confidence interval (95%CI) 1.75–2.90, p < 0.001), type of place of residence (OR 0.37, 95%CI 0.18–0.74, p = 0.005), maternal anaemia (OR 1.74, 95%CI 1.39–2.17, p < 0.001), and malaria infection (OR 2.82, 95%CI 1.56–5.11, p < 0.001) were the identified predictors of anaemia in the whole cohort. In younger children, only the economic class was an anaemia predictor, with a lower anaemia risk among the rich wealth class (OR 2.70, 95%CI 1.29–5.62, p = 0.008). However, in older children, three anaemia predictors were identified. These are maternal anaemia (OR 1.79, 95%CI 1.40–2.28, < 0.001), malaria infection (OR 2.77, 95%CI 1.48–5.21, p = 0.002), and type of residency (where camps’ residents were less likely affected with anaemia than rural children (OR 0.38, 95%CI 0.17–0.87, p = 0.022)).

Conclusions

About half of the under-5 children in Sudan are anaemic, with worse prevalence in younger children. Efforts targeted at improving socio-economic status, decreasing maternal anaemia and childhood malaria infection may mitigate this alarming trend.

Maternal and newborn healthcare practices: assessment of the uptake of lifesaving services in Hoima District, Uganda

BACKGROUND

The current maternal mortality ratio in Uganda is 336 maternal deaths per 100,000 live births. Infant mortality is 43 deaths per 1000 live births, with 42% of the mortality occurring during the neonatal period. This might be related to a weak health system in the country. This study aimed at assessing the uptake of lifesaving services during pregnancy and childbirth in Hoima District, Uganda.

METHODS

The study used a cross-sectional quantitative design among 691 women with a child under 5 years. Households were randomly sampled from a list of all the villages in the district with the ENA for SMART software using the EPI methodology. Pre-coded questionnaires uploaded in the Open Data Kit were used for data collection. The data was cleaned and analysed using MS Excel and SPSS software. Descriptive results are presented.

RESULTS

Of the 55.1% women attending at least four antenatal care (ANC) visits, only 24.3% had the first ANC within the first trimester. Moreover, ANC services generally was of poor quality, with only 0.4% meeting all the requirements for quality of ANC service. The highest contributors to this poor quality included poor uptake of iron-folic acid (adherence 28.8%), the six-required birth preparedness and complication readiness items (13.2%), and recognition of the seven danger signs of pregnancy (3.0%). Adherence to the seven essential newborn care actions was very low (0.5%), mainly caused by three practices: initiating breastfeeding within 1 h (59.9%), lack of postnatal care within 24 h (20.1%), and failure to recognize the 6 danger signs of the newborn (2.4%). Only 11.1% of the males participated in all maternal and newborn care requirements, by encouraging women to seek healthcare (39.9%), accompanying them to healthcare (36.9%), and HIV counselling and support services (26.2%).

CONCLUSION

The study reveals poor maternal and newborn practices throughout the continuum of care, from ANC and skilled birth attendance to newborn care during childbirth. With such poor results, it is not surprising that Hoima is sixth of 10 districts that have the highest numbers of deaths due to maternal mortality in Uganda.

Prevalence and determinants of anaemia in women of reproductive age in Sudan: analysis of a cross-sectional household survey

BACKGROUND

Anaemia is a global health problem and women in reproductive age (WRA) are amongst the most affected population. Its consequences include low birth weight and maternal mortality. This study aimed to assess the prevalence of anaemia and to identify its determinants in Sudanese women in reproductive age.

METHODS

A population-based cross-sectional study was conducted in Sudan in 2016. A multi-stage stratified cluster sampling design was executed with consideration of rural population, urban population, and internally displaced persons/refugees camps residents. All women in reproductive age (15-49 years), classified by pregnancy status, in the targeted households were surveyed and personal characteristic data were collected. Their haemoglobin level and malaria infection (using rapid diagnostic test, RDT) were assessed. The World Health Organization (WHO) haemoglobin level cut-off for defining anaemia and severe anaemia in pregnant and non-pregnant women was used. Logistic regression analyses were performed.

RESULTS

A total of 4271 women (WRA) of which 421 (9.9%) pregnant women (PW) were included in the study. The overall anaemia prevalence in WRA was 35.6%. It was 36.0 and 35.5% in PW and non-pregnant women (NPW), respectively. The average haemoglobin level was found to be 113.9 g/L (SD 16.3) and 123.2 g/L (SD 15.7) for PW and NPW respectively. Severe anaemia prevalence was 1.2% in each group. In the logistic regression model, anaemia was associated with malaria infection in PW (aOR 4.100, 95%CI 1.523-11.039, p = 0.003), NPW (aOR 2.776, 95%CI 1.889-4.080, p < 0.001), and WRA (aOR 2.885, 95%CI 2.021-4.119, p < 0.001). Other identified determinants of anaemia in NPW was living in camps (aOR 1.499, 95%CI 1.115-2.017, p = 0.007) and in WRA was being in the poorest economic class (aOR 1.436, 95%CI 1.065-1.936, p = 0.018).

CONCLUSIONS

Anaemia is a public health problem in Sudan. The study supported the association between malaria infection and anaemia, but not with low and moderate malaria transmission areas. Resources need to be allocated for all anaemic populations with special attention for the populations in most need and interventions need to be implemented based on local variations. Malaria control interventions, specifically case management, may have a major impact in reducing anaemia prevalence in low to moderate malaria transmission areas.

The Power of Trading: Exploring the Value of a Trading Shop as a Health-Promoting Community Engagement Approach

Involving and engaging vulnerable communities from the very beginning is important if we wish to enhance general well-being. With a focus on equal partnership with low-socioeconomic status (SES) families, a Trading Shop in Vaals was developed as a community engagement initiative. In the current study, we focused on the participation process, from preparation to sustaining the Trading Shop, in order to define whether the Trading Shop can be successful in engaging families through focusing specially on their needs and perceived positive health. A formative case study design was carried out to monitor, evaluate, and timely adjust the developments within the Trading Shop by using participatory action research. The Trading Shop was monitored from its preparation to its opening, as well as during the start and the steps taken towards continuation in the form of municipal policy. The results showed one central theme during all phases: the optimal navigation between top-down support from professionals and bottom-up developments among the volunteers in the Trading Shop. With the input from both approaches, it was possible to create an optimal environment for the volunteers to achieve personal development. The inclusivity and accessibility of the Trading Shop as a community engagement initiative offered the opportunity to volunteers to enhance their needs, realizing personal growth and development of their talents in several positive health domains.

Investigating longitudinal context-specific physical activity patterns in transition from primary to secondary school using accelerometers, GPS, and GIS

INTRODUCTION

Previous longitudinal studies indicate that physical activity (PA) significantly declines from primary-to secondary school, and report both changes in individual and environmental determinants of PA. In order to understand this transition and to prevent this negative trend, it is important to gather contextually rich data on possible mechanisms that drive this decline. Therefore, the aim of this study was to investigate changes of PA patterns in transition between primary and secondary school, and to add domain-specific insights of how, where, and when these changes occur.

METHODS

In total, 175 children participated in a 7-day accelerometer- and Global Positioning System (GPS) protocol at their last year of primary and their first year of secondary school. GPS data-points were overlaid with Geographical Information Systems (GIS) data using ArcGIS 10.1 software. Based on the GPS locations of individual data-points, we identified child's PA at home, school, local sports grounds, shopping centers, and other locations. Also, trips in active and passive transport were identified according to previously validated GPS speed-algorithms. Longitudinal multi-level linear mixed models were fitted adjusting for age, gender, meteorological circumstances, and the nested structure of days within children and children within schools. Outcome measures were minutes spent in light PA and moderate-to-vigorous PA, specified for the time-segments before school, during school, after school and weekend days.

RESULTS

Total PA significantly declined from primary to secondary school. Although transport-related PA increased before- and during school, decreases were found for especially afterschool time spent at sports grounds and transport-related PA during weekends.

CONCLUSIONS

This is the first study that demonstrated longitudinal changes of context- and domain-specific PA patterns in transition between primary and secondary school, based on device-assessed PA. Given the importance of this transition-period for the development of long-term PA patterns, results from this study warrant the development of evidence-based PA programs in this transition period, while acknowledging the integrative role of schools, parents, and afterschool sports providers. More specifically, the results underline the need to increase children's PA levels in primary schools, promote afterschool PA at secondary schools, and to prevent the drop-out in sports participation at secondary schools.

Small Successes Make Big Wins: A Retrospective Case Study towards Community Engagement of Low-SES Families

In health-promoting interventions, a main difficulty is that low socioeconomic status (SES) groups especially seem to experience barriers to participation. To overcome this barrier, the current study focused on the success factors and obstacles in the process of supporting low-SES families in becoming partners, while carrying out small-scale activities based on their needs. A retrospective case study design was used to construct a timeline of activities organized by and together with low-SES families based on mainly qualitative data. Next, key events were grouped into the four attributes of the resilience activation framework: human, social, political, and economic capital. The following key lessons were defined: professionals should let go of work routines and accommodate the talents of the families, start doing, strive for small successes; create a functional social network surrounding the families, maintaining professional support over time as back-up; and create collaborative governance to build upon accessibility, transparency and trust among the low-SES families. Continuous and flexible ‘navigating the middle’ between bottom-up and top-down approaches was seen as vital in the partnership process between low-SES families and local professional partners. Constant feedback loops made the evaluation points clear, which supported both families and professionals to enhance their partnership.

The influence of preschoolers' emotional and behavioural problems on obesity treatment outcomes: Secondary findings from a randomized controlled trial

BACKGROUND

Few studies have explored the influence of preschoolers' behavioural problems on obesity treatment.

OBJECTIVES

To assess emotional and behavioural problems before and after an obesity intervention and examine relationships between changes in child behaviour and changes in weight status.

METHOD

The study included 77 children (4-6 years old, 53% girls, mean body mass index [BMI] z-score of 3.0 [SD 0.6]) who participated in the More and Less Study, a randomized controlled trial. Families were randomized to a parenting program or to standard treatment. The children's heights and weights (BMI z-score, primary outcome) were measured at baseline and 12 months post baseline. Parents rated their children's behaviours (secondary outcome) on the Child Behavior Checklist (CBCL) for ages 1.5 to 5 years, a questionnaire that measures psychosocial health and functioning, encompassing emotional and behavioural problems. Changes in child behaviour during treatment were examined through paired samples t tests; the influence of child behaviour on treatment effects was examined through linear regressions.

RESULTS

Child emotional and behavioural problems significantly improved after obesity treatment. Lower scores were found for Emotional Reactivity, Sleep Problems, Affective Problems, Aggressive Behaviour, Externalizing Behaviours, Oppositional Defiant Problems, and Total Problems. Child behaviour significantly affected obesity treatment results: Attention Problems and attention deficit hyperactivity disorder (ADHD) at baseline contributed to increasing BMI z-scores, whereas Oppositional Defiant Problems, Externalizing Behaviours, and a higher number of behavioural problems predicted decreasing BMI z-scores.

CONCLUSIONS

Child behaviours at baseline influenced treatment results. Child emotional and behavioural problems improved post treatment. The results suggest that obesity treatment may help in reducing emotional distress among preschoolers.

The Comprehensive Community Engagement Framework for Health and Well-being

Background

Community engagement (CE) and empowerment are required to support the sustainability and effectiveness of actions to reach Agenda 2030. There is a need to guide CE for health and well-being to take action on important societal challenges such as the growing burden of non-communicable diseases (NCDs) and health inequities. The framework proposed in this study has been designed to assist professionals, practitioners and communities to effectively engage.

Methods

A narrative review of existing grey literature, policy papers and models related to CE was performed. This guided the development of a systematic search strategy, performed by two researchers, which reviewed CE approaches and key influencing factors. The search strategy captured different terms used for CE.

Results

A total of 27 studies of different types, from around the world, were identified for inclusion into the review. The study compiled a set of widely-used theories and approaches to CE. Key factors such as governance, trust, accessibility and sociocultural contextualisation were also identified as important for the success of CE initiatives. Subsequently, the Comprehensive Community Engagement Framework (CCEF) was developed. It combines theoretical and empirical principles, proven participatory actions and key factors to produce evidence-based health and well-being outcomes across different sectors and levels of society.

Conclusions

This study has formed the basis of a forthcoming WHO report on CE. The CCEF enables the operationalisation of CE to guide for possible practical approaches to planning, initiating, sustaining and evaluating CE processes alongside the community. It can be used by the health sector as well as the non-health sectors to address health, well-being and broader societal challenges.

Key messages

The CCEF can be used to engage health and non-health stakeholders to tailor CE processes, increase impact of interventions and policies, building capacity and empowering communities. The proposed framework provides the first comprehensive guidance to conduct community engagement.

The implementation of the coaching on lifestyle (CooL) intervention: lessons learnt

Background

Combined lifestyle interventions (CLIs) are designed to help people who are overweight or obese maintain a healthy new lifestyle. The CooL intervention is a CLI in the Netherlands, in which lifestyle coaches counsel adults and children (and/or their parents) who are obese or at high risk of obesity to achieve a sustained healthier lifestyle. The intervention consists of coaching on lifestyle in group and individual sessions, addressing the topics of physical activity, dietary behaviours, sleep, stress management and behavioural change. The aim of this study was to evaluate the implementation process of the Coaching on Lifestyle (CooL) intervention and its facilitating and impeding factors.

Methods

Mixed methods were used in this action-oriented study. Both quantitative (number of referrals, attendance lists of participants and questionnaires) and qualitative (group and individual interviews, observations, minutes and open questions) data were collected among participants, lifestyle coaches, project group members and other stakeholders. The Consolidated Framework for Implementation Research was used to analyse the data.

Results

CooL was evaluated by stakeholders and participants as an accessible and useful programme, because of its design and content and the lifestyle coaches’ approach. However, stakeholders indicated that the lifestyle coaches need to become more familiar in the health care network and public sectors in the Netherlands. Lifestyle coaching is a novel profession and the added value of the lifestyle coach is not always acknowledged by all health care providers. Lifestyle coaches play a crucial role in ensuring the impact of CooL by actively networking, using clear communication materials and creating stakeholders’ support and understanding.

Conclusion

The implementation process needs to be strengthened in terms of creating support for and providing clear information about lifestyle coaching. The CooL intervention was implemented in multiple regions, thanks to the efforts of many stakeholders. Lifestyle coaches should engage in networking activities and entrepreneurship to boost the implementation process. It takes considerable time for a lifestyle coach to become fully incorporated in primary care.

Unravelling the Effects of the Healthy Primary School of the Future: For Whom and Where Is It Effective?

The 'Healthy Primary School of the Future' (HPSF) aims to integrate health and well-being within the whole school system. This study examined the two-year effects of HPSF on children's dietary and physical activity (PA) behaviours at school and at home and investigated whether child characteristics or the home context moderated these effects. This study (n = 1676 children) has a quasi-experimental design with four intervention schools, i.e., two full HPSF (focus: nutrition and PA), two partial HPSF (focus: PA), and four control schools. Measurements consisted of accelerometry (Actigraph GT3X+) and questionnaires. Favourable effects on children's dietary and PA behaviours at school were found in the full HPSF; in the partial HPSF, only on PA behaviours. Children in the full HPSF did not compensate at home for the improved health behaviours at school, while in the partial HPSF, the children became less active at home. In both the full and partial HPSF, less favourable effects at school were found for younger children. At home, less favourable effects were found for children with a lower socioeconomic status. Overall, the effect of the full HPSF on children's dietary and PA behaviours was larger and more equally beneficial for all children than that of the partial HPSF.

Randomized phase-II trial evaluating induction therapy with idarubicin and etoposide plus sequential or concurrent azacitidine and maintenance therapy with azacitidine

The aim of this randomized phase-II study was to evaluate the effect of substituting cytarabine by azacitidine in intensive induction therapy of patients with acute myeloid leukemia (AML). Patients were randomized to four induction schedules for two cycles: STANDARD (idarubicin, cytarabine, etoposide); and azacitidine given prior (PRIOR), concurrently (CONCURRENT), or after (AFTER) therapy with idarubicin and etoposide. Consolidation therapy consisted of allogeneic hematopoietic-cell transplantation or three courses of high-dose cytarabine followed by 2-year maintenance therapy with azacitidine in the azacitidine-arms. AML with CBFB-MYH11, RUNX1-RUNX1T1, mutated NPM1, and FLT3-ITD were excluded and accrued to genotype-specific trials. The primary end point was response to induction therapy. The statistical design was based on an optimal two-stage design applied for each arm separately. During the first stage, 104 patients (median age 62.6, range 18-82 years) were randomized; the study arms PRIOR and CONCURRENT were terminated early due to inefficacy. After randomization of 268 patients, all azacitidine-containing arms showed inferior response rates compared to STANDARD. Event-free and overall survival were significantly inferior in the azacitidine-containing arms compared to the standard arm (p < 0.001 and p = 0.03, respectively). The data from this trial do not support the substitution of cytarabine by azacitidine in intensive induction therapy.

The Moderating Role of the School Context on the Effects of the Healthy Primary School of the Future

Background: The current study investigated the moderating role of the school context on the effects of a Dutch health promoting school initiative on children's health and health behaviors. Methods: The study used a mixed-methods design. The school context (n = 4) was assessed by the characteristics of the school population, teacher's health-promoting (HP) practices, implementers' perceived barriers, school's HP elements, and dominating organizational issues. Outcomes included objectively assessed BMI z-scores and physical activity (PA), and parent and child-reported dietary intake. Analyses included linear mixed models (four intervention schools versus four control schools), and qualitative comparisons between intervention schools with similar HP changes. Results: Effects on outcomes varied considerably across schools (e.g., range in effect size on light PA of 0.01-0.26). Potentially moderating contextual aspects were the child's socioeconomic background and baseline health behaviors; practices and perceived barriers of employees; and organizational issues at a school level. Conclusions: Similar HP changes lead to different outcomes across schools due to differences in the school context. The adoption of a complex adaptive systems perspective contributes to a better understanding of the variation in effects and it can provide insight on which contextual aspects to focus on or intervene in to optimize the effects of HP initiatives.

Overweight and obesity among adults in the Gulf States: A systematic literature review of correlates of weight, weight-related behaviours, and interventions

Obesity has increased to an epidemic level in the Gulf States. This systematic review is the first to explore the scientific evidence on correlates and interventions for overweight (body mass index [BMI] ≥ 25) or weight-related behaviours in the region. A systematic search of peer-reviewed articles was conducted using PubMed and PsycINFO. Ninety-one studies were eligible for this review including 84 correlate studies and seven intervention studies. Correlate studies of overweight focused on sociodemographic factors, physical activity, and dietary habits. Low physical activity, sedentary behaviour, and unhealthy dietary habits were associated with overweight. The most-reported sociodemographic correlates of overweight were increased age, being married, low education, urban residence, and unemployment. Correlate studies of physical activity and dietary behaviours mostly focused on sociodemographic variables. Being female and increased age (the latter less consistently) were associated with low physical activity. Interventions were very heterogeneous with respect to the target group, intensity, and behavioural strategies used. The effectiveness of interventions was difficult to evaluate because of the chosen study design or outcome measure, the small sample size, or high attrition rate. Few studies have investigated sociocognitive and environmental determinants of weight-related behaviours. Such information is crucial to developing health promotion initiatives that target those weight-related behaviours.

Population Characteristics and Needs of Informal Caregivers Associated With the Risk of Perceiving a High Burden: A Cross-Sectional Study

This study explored the population characteristics and needs of informal caregivers reporting a low or high burden. A cross-sectional study was conducted in the Netherlands to explore the associations between the characteristics and needs of informal caregivers and the burden they perceive and to assess the variance in perceived burdens that is explained by these variables. Three thousand sixty-seven adult informal caregivers and 1936 senior informal caregivers participated, almost 15% of whom perceived a high burden. Particularly caregivers in the 40 to 54 age group perceived a high burden, while caregivers with an intermediate educational level reported a low burden. Higher burden was also reported by caregivers who spent more time on the care provision tasks, had a high level of depressive symptoms, or reported loneliness. The explored variables seem to be important to explain caregiver burden. Longitudinal research is warranted to establish the causal directions of these associations.

Shining light inside the tunnel: using photovoice as a strategy to define the needs for health promotion among families of low socioeconomic status

PURPOSE

This study aimed to identify opportunities to improve the current health and social situation of low socioeconomic status (SES) families and to gain a better understanding of the main needs regarding health promotion. Low-SES families were approached to participate in a photovoice study.

METHOD

The study took place in the municipality of Vaals, which is located in the southernmost part of the Netherlands. A diverse group of ten people from eight different families took about 150 photographs within their community on topics they considered important for their health and quality of life. This was followed by individual interviews and a focus group interview.

RESULTS

Four main needs were identified: meeting each other, helping each other, feeling safe and being mobile. The photographs showed that health-related themes had low priority for these families.

CONCLUSION

The low-SES families focused on upstream factors relating to independence, self-resilience and a sense of belonging, to help them cope with their current situation. This study represents a first step towards the development of a community approach to health promotion in low-SES families.

With whom are you dealing? Using social network analysis as a tool to strengthen service delivery structures for low socioeconomic status populations

Background: Health disparities between populations with different socioeconomic status (SES) are increasing. Although a wide variety of support service organizations and arrangements are in place, no general overview of this social network, its reach, and harmonization of services surrounding low-SES populations are available. The present participatory health research study examined the current network structure and the utility of using social network analysis (SNA) as a tool to improve service delivery structures. Design and methods: We applied a mixed-methods study design. An online-questionnaire was used to examine the relationships among organizations assumed to support low-SES individuals in the municipality of Vaals, the Netherlands. In addition, semi-structured interviews and a networking session were used to examine the current network structure and to explore opportunities for improvement. Results: The SNA revealed a weak network structure, and all interviewed professionals mentioned that the current structure should be improved. Participants indicated that a first step would be to install a central information system. Conclusions: SNA can be a useful tool to gain more in-depth insights into the relations within a service delivery network. The professionals were assisted in discovering new organizations that could help them reach low SES populations and in harmonizing and improving their service delivery.

The 2017 Dutch Physical Activity Guidelines

Background

The objective of this study was to derive evidence-based physical activity guidelines for the general Dutch population.

Methods

Two systematic reviews were conducted of English language meta-analyses in PubMed summarizing separately randomized controlled trials and prospective cohort studies on the relation between physical activity and sedentary behaviour on the one hand and the risk of all-cause mortality and incidence of 15 major chronic diseases and conditions on the other hand. Other outcome measures were risk factors for cardiovascular disease and type 2 diabetes, physical functioning, and fitness. On the basis of these reviews, an expert committee derived physical activity guidelines. In deriving the guidelines, the committee first selected only experimental and observational prospective findings with a strong level of evidence and then integrated both lines of evidence.

Results

The evidence found for beneficial effects on a large number of the outcome measures was sufficiently strong to draw up guidelines to increase physical activity and reduce sedentary behaviour, respectively. At the same time, the current evidence did not provide a sufficient basis for quantifying how much physical activity is minimally needed to achieve beneficial health effects, or at what amount sedentary behaviour becomes detrimental. A general tenet was that at every level of current activity, further increases in physical activity provide additional health benefits, with relatively larger effects among those who are currently not active or active only at light intensity. Three specific guidelines on (1) moderate- and vigorous-intensity physical activity, (2) bone- and muscle-strengthening activities, and (3) sedentary behaviour were formulated separately for adults and children.

Conclusions

There is an unabated need for evidence-based physical activity guidelines that can guide public health policies. Research in which physical activity is measured both objectively (quantity) and subjectively (type and quality) is needed to provide better estimates of the type and actual amount of physical activity required for health.

The Coaching on Lifestyle (CooL) Intervention for Overweight and Obesity: A Longitudinal Study into Participants' Lifestyle Changes

Combined lifestyle interventions (CLIs) can be effective in reducing weight and improving lifestyle-related behaviours but it is unclear how CLIs can best be implemented in practice in order to achieve sustained lifestyle changes. The Coaching on Lifestyle programme (CooL) is a CLI in the Netherlands, in which professional lifestyle coaches counsel adults and children (and/or their parents) who are obese or at high risk of obesity to achieve a sustained healthier lifestyle. The CooL intervention consists of group and individual sessions addressing the topics of physical activity, dietary behaviours, sleep and stress. Our longitudinal one-group pre-post study aimed to identify lifestyle changes among participants (adults, children and their parents) at 8 and 18 months after initiation. We assessed constructs ranging from motivation and behaviour-specific cognitions to behaviours and health outcomes. Positive and sustained changes among adults were found regarding perceived autonomy, motivation, perceived barriers, lifestyle behaviours, quality of life and weight. Among children and their parents, few improvements were found regarding behaviours and quality of life. CooL has been successful in coaching adult participants towards sustained behavioural change during the intervention period. Mixed results and smaller effect sizes were found for children and their parents.

Assessment of imatinib as first-line treatment of chronic myeloid leukemia: 10-year survival results of the randomized CML study IV and impact of non-CML determinants

Chronic myeloid leukemia (CML)-study IV was designed to explore whether treatment with imatinib (IM) at 400 mg/day (n=400) could be optimized by doubling the dose (n=420), adding interferon (IFN) (n=430) or cytarabine (n=158) or using IM after IFN-failure (n=128). From July 2002 to March 2012, 1551 newly diagnosed patients in chronic phase were randomized into a 5-arm study. The study was powered to detect a survival difference of 5% at 5 years. After a median observation time of 9.5 years, 10-year overall survival was 82%, 10-year progression-free survival was 80% and 10-year relative survival was 92%. Survival between IM400 mg and any experimental arm was not different. In a multivariate analysis, risk group, major-route chromosomal aberrations, comorbidities, smoking and treatment center (academic vs other) influenced survival significantly, but not any form of treatment optimization. Patients reaching the molecular response milestones at 3, 6 and 12 months had a significant survival advantage. For responders, monotherapy with IM400 mg provides a close to normal life expectancy independent of the time to response. Survival is more determined by patients' and disease factors than by initial treatment selection. Although improvements are also needed for refractory disease, more life-time can currently be gained by carefully addressing non-CML determinants of survival.

Playability of school-environments and after-school physical activity among 8-11 year-old children: specificity of time and place

Background

Physical Activity (PA) occurs in several behavioral domains (e.g., sports, active transport), and is affected by distinct environmental factors. By filtering objective PA using children’s school schedules, daily PA can be separated into more conceptually meaningful domains. We used an ecological design to investigate associations between “playability” of 21 school-environments and children’s objectively measured after-school PA. We also examined to what extent distinct time-periods after-school and the distance from children’s residence to their school influenced this association.

Methods

PA was measured in 587 8–11 year-old children by accelerometers, and separated in four two-hour time-periods after-school. For each school-environment, standardized playability-scores were calculated based on standardized audits within 800 m network buffers around each school. Schools and children’s residences were geocoded, and we classified each child to be residing in 400, 800, 1600, or >1600 m crow-fly buffers from their school. The influence of network-distance buffers was also examined using the same approach.

Results

Playability was associated with light PA and moderate-to-vigorous PA after-school, especially in the time-period directly after-school and among children who lived within 800 m from their school. Playability explained approximately 30 % of the after-school PA variance between schools. Greater distance from children’s residence to their school weakened the association between playability of the school-environments and after-school PA.

Conclusions

This study demonstrated that relationships between the conceptually matched physical environment and PA can be revealed and made plausible with increasing specificity in time and distance.

Association between prenatal and current exposure to selected LCPUFAs and school performance at age 7

INTRODUCTION

Long-chain polyunsaturated fatty acids (LCPUFAs) are important for brain functioning and might, thus, influence cognition and school performance. However, research investigating LCPUFAs relationships with school performance is limited. The objective of this study was to determine the association between levels of the LCPUFAs docosahexaenoic acid (DHA), arachidonic acid (AA), eicosapentaenoic acid (EPA) and n-6 docosapentaenoic acid (Osbond acid, ObA) at study entry, 22 weeks of pregnancy, 32 weeks of pregnancy, at partus, in umbilical cord plasma and child's plasma at age 7 and school performance scores at age 7.

METHODS

Data from the Maastricht Essential Fatty Acid Birth cohort (MEFAB) were used for this study. Fatty acid levels of plasma phospholipids were measured in maternal blood plasma at study entry, 22 weeks of pregnancy, 32 weeks of pregnancy and partus. Childs fatty acid levels of plasma phospholipids were measured a in umbilical cord blood plasma, and in blood plasma of the child at age 7. Scores on national standardised tests for spelling, reading and arithmetic at age 7 were obtained via the school (scores were available for 149, 159 and 155 children, respectively). Associations between LCPUFA levels and school performance scores were analysed with categorical regression analyses with correction for covariates (smoking, maternal education, sex, breastfeeding, maternal intelligence, birth weight and BMI at age 7).

RESULTS

Significant (p<0.001) associations between DHA level at age 7 and both reading (β=0.158) and spelling (β=0.146) were found. Consistent significant negative associations were observed between all maternal DHA plasma levels and arithmetic scores at age 7 (all p<0.001, all β<-0.019). Additional significant negative associations were observed between maternal LCPUFA plasma levels at study entry and both reading and spelling scores at age 7; these associations were less consistent.

CONCLUSION

Plasma DHA levels at age 7 were positively associated with reading and spelling scores at age 7. Consistent significant negative associations between maternal plasma DHA levels and arithmetic scores of the child at age 7 were found. Although this is an observational study, which cannot proof causality, the consistent negative associations observed between maternal plasma DHA levels and the arithmetic scores of the children at age 7 calls upon prudence when considering DHA supplementation during pregnancy.

Bits and pieces. Food texture influences food acceptance in young children

BACKGROUND

Picky or fussy eating is common in early childhood and associated with a decreased preference for a variety of foods. The aim of the current study was to test experimentally which sensory food feature influences food acceptance, which, in turn is an indication for fussy eating, in young children (32 - 48 months). Another aim was to evaluate if the behavioural measurement of food acceptance is related to parental reports of their child's fussy eating behaviour, parental feeding styles and children's BMI.

METHOD

In a repeated-measures-design, three sensory features were manipulated separately (i.e., colour, texture and taste) while keeping the other two features constant. The baseline measurement consisted of a well-liked yoghurt, which was presented before each manipulation variant. The number of spoons that children (N = 32) consumed from each variant were registered as behavioural indication for food acceptance. Parental reports of children's eating behaviour and parental feeding styles; and children's BMI were also measured.

RESULTS

The manipulation of food texture caused a significant decrease in intake. Colour and taste manipulations of the yoghurt did not affect children's intake. Parental reports of children's fussy eating behaviour and parental feeding styles were not related to the behavioural observation of food acceptance. The behavioural measurement of food acceptance and parental accounts of fussy eating were not related to children's BMI.

CONCLUSION

Food texture but not taste or colour alternations affected food acceptance, at least when consuming variations of a well-liked yoghurt. This knowledge is important for further research on picky-eating interventions. Parental reports of fussy eating did not concur with the behavioural observation of food acceptance. Further research is warranted to test whether these findings generalize to other food types.

Survival after neoadjuvant chemotherapy with or without bevacizumab or everolimus for HER2-negative primary breast cancer (GBG 44-GeparQuinto)†

BACKGROUND

The GeparQuinto study showed that adding bevacizumab to 24 weeks of anthracycline-taxane-based neoadjuvant chemotherapy increases pathological complete response (pCR) rates overall and specifically in patients with triple-negative breast cancer (TNBC). No difference in pCR rate was observed for adding everolimus to paclitaxel in nonearly responding patients. Here, we present disease-free (DFS) and overall survival (OS) analyses.

PATIENTS AND METHODS

Patients (n = 1948) with HER2-negative tumors of a median tumor size of 4 cm were randomly assigned to neoadjuvant treatment with epirubicin/cyclophosphamide followed by docetaxel (EC-T) with or without eight infusions of bevacizumab every 3 weeks before surgery. Patients without clinical response to EC ± Bevacizumab were randomized to 12 weekly cycles paclitaxel with or without everolimus 5 mg/day. To detect a hazard ratio (HR) of 0.75 (α = 0.05, β = 0.8) 379 events had to be observed in the bevacizumab arms.

RESULTS

With a median follow-up of 3.8 years, 3-year DFS was 80.8% and 3-year OS was 89.7%. Outcome was not different for patients receiving bevacizumab (HR 1.03; P = 0.784 for DFS and HR 0.974; P = 0.842 for OS) compared with patients receiving chemotherapy alone. Patients with TNBC similarly showed no improvement in DFS (HR = 0.99; P = 0.941) and OS (HR = 1.02; P = 0.891) when treated with bevacizumab. No other predefined subgroup (HR+/HER2-; locally advanced (cT4 or cN3) or not; cT1-3 or cT4; pCR or not) showed a significant benefit. No difference in DFS (HR 0.997; P = 0.987) and OS (HR 1.11; P = 0.658) was observed for nonearly responding patients receiving paclitaxel with or without everolimus overall as well as in subgroups.

CONCLUSIONS

Long-term results, in opposite to the results of pCR, do not support the neoadjuvant use of bevacizumab in addition to an anthracycline-taxane-based chemotherapy or everolimus in addition to paclitaxel for nonearly responding patients.

Effects of an intervention aimed at reducing the intake of sugar-sweetened beverages in primary school children: a controlled trial

BACKGROUND

Since sugar-sweetened beverages (SSB) may contribute to the development of overweight in children, effective interventions to reduce their consumption are needed. Here we evaluated the effect of a combined school- and community-based intervention aimed at reducing children's SSB consumption by promoting the intake of water. Favourable intervention effects on children's SSB consumption were hypothesized.

METHODS

In 2011-2012, a controlled trial was conducted among four primary schools, comprising 1288 children aged 6-12 years who lived in multi-ethnic, socially deprived neighbourhoods in Rotterdam, the Netherlands. Intervention schools adopted the 'water campaign', an intervention developed using social marketing. Control schools continued with their regular health promotion programme. Primary outcome was children's SSB consumption, measured using parent and child questionnaires and through observations at school, both at baseline and after one year of intervention.

RESULTS

Significant positive intervention effects were found for average SSB consumption (B -0.19 litres, 95% CI -0.28;-0.10; parent report), average SSB servings (B -0.54 servings, 95% CI -0.82;-0.26; parent report) and bringing SSB to school (OR 0.51, 95% CI 0.36;0.72; observation report).

CONCLUSIONS

This study supports the effectiveness of the water campaign intervention in reducing children's SSB consumption. Further studies are needed to replicate our findings.

General and food-specific parenting: measures and interplay

BACKGROUND

Parental influence on child food intake is typically conceptualized at three levels-parenting practices, feeding style, and parenting style. General parenting style is modeled at the most distal level of influence and food parenting practices are conceptualized as the most proximal level of influence. The goal of this article is to provide insights into contents and explanatory value of instruments that have been applied to assess food parenting practices, feeding style, and parenting style.

METHODS

Measures of food parenting practices, feeding style, and parenting style were reviewed, compared, and contrasted with regard to contents, explanatory value, and interrelationships.

RESULTS

Measures that are used in the field often fail to cover the full scope and complexity of food parenting. Healthy parenting dimensions have generally been found to be positively associated with child food intake (i.e., healthier dietary intake and less intake of energy-dense food products and sugar-sweetened beverages), but effect sizes are low. Evidence for the operation of higher-order moderation has been found, in which the impact of proximal parental influences is moderated by more distal levels of parenting.

CONCLUSIONS

Operationalizing parenting at different levels, while applying a contextual higher-order moderation approach, is advocated to have surplus value in understanding the complex process of parent-child interactions in the area of food intake. A research paradigm is presented that may guide future work regarding the conceptualization and modeling of parental influences on child dietary behavior.

Food parenting measurement issues: working group consensus report

Childhood obesity is a growing problem. As more researchers become involved in the study of parenting influences on childhood obesity, there appears to be a lack of agreement regarding the most important parenting constructs of interest, definitions of those constructs, and measurement of those constructs in a consistent manner across studies. This article aims to summarize findings from a working group that convened specifically to discuss measurement issues related to parental influences on childhood obesity. Six subgroups were formed to address key measurement issues. The conceptualization subgroup proposed to define and distinguish constructs of general parenting styles, feeding styles, and food parenting practices with the goal of understanding interrelating levels of parental influence on child eating behaviors. The observational subgroup identified the need to map constructs for use in coding direct observations and create observational measures that can capture the bidirectional effects of parent-child interactions. The self-regulation subgroup proposed an operational definition of child self-regulation of energy intake and suggested future measures of self-regulation across different stages of development. The translational/community involvement subgroup proposed the involvement of community in the development of surveys so that measures adequately reflect cultural understanding and practices of the community. The qualitative methods subgroup proposed qualitative methods as a way to better understand the breadth of food parenting practices and motivations for the use of such practices. The longitudinal subgroup stressed the importance of food parenting measures sensitive to change for use in longitudinal studies. In the creation of new measures, it is important to consider cultural sensitivity and context-specific food parenting domains. Moderating variables such as child temperament and child food preferences should be considered in models.

What moves them? Active transport among inhabitants of Dutch deprived districts

BACKGROUND

Active modes of transport like walking and cycling have been shown to be valuable contributions to daily physical activity. The current study investigates associations between personal and neighbourhood environmental characteristics and active transport among inhabitants of Dutch deprived districts.

METHOD

Questionnaires about health, neighbourhoods, and physical activity behaviour were completed by 742 adults. Data was analysed by means of multivariate linear regression analyses.

RESULTS

Being younger, female, and migrant and having a normal weight were associated with more walking for active transport. Being younger, male, and native Dutch and having a normal weight were associated with more cycling for active transport. Neighbourhood characteristics were generally not correlated with active transport. Stratified analyses, based on significant person-environment interactions, showed that migrants and women walked more when cars did not exceed maximum speed in nearby streets and that younger people walked more when speed of traffic in nearby streets was perceived as low. Among migrants, more cycling was associated with the perceived attractiveness of the neighbourhood surroundings.

DISCUSSION AND CONCLUSION

Results indicated that among inhabitants of Dutch deprived districts, personal characteristics were associated with active transport, whereas neighbourhood environmental characteristics were generally not associated with active transport. Nevertheless, interaction effects showed differences among subgroups that should be considered in intervention development.

Treatment of older patients with mantle-cell lymphoma

BACKGROUND

The long-term prognosis for older patients with mantle-cell lymphoma is poor. Chemoimmunotherapy results in low rates of complete remission, and most patients have a relapse. We investigated whether a fludarabine-containing induction regimen improved the complete-remission rate and whether maintenance therapy with rituximab prolonged remission.

METHODS

We randomly assigned patients 60 years of age or older with mantle-cell lymphoma, stage II to IV, who were not eligible for high-dose therapy to six cycles of rituximab, fludarabine, and cyclophosphamide (R-FC) every 28 days or to eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 21 days. Patients who had a response underwent a second randomization to maintenance therapy with rituximab or interferon alfa, each given until progression.

RESULTS

Of the 560 patients enrolled, 532 were included in the intention-to-treat analysis for response, and 485 in the primary analysis for response. The median age was 70 years. Although complete-remission rates were similar with R-FC and R-CHOP (40% and 34%, respectively; P=0.10), progressive disease was more frequent with R-FC (14%, vs. 5% with R-CHOP). Overall survival was significantly shorter with R-FC than with R-CHOP (4-year survival rate, 47% vs. 62%; P=0.005), and more patients in the R-FC group died during the first remission (10% vs. 4%). Hematologic toxic effects occurred more frequently in the R-FC group than in the R-CHOP group, but the frequency of grade 3 or 4 infections was balanced (17% and 14%, respectively). In 274 of the 316 patients who were randomly assigned to maintenance therapy, rituximab reduced the risk of progression or death by 45% (in remission after 4 years, 58%, vs. 29% with interferon alfa; hazard ratio for progression or death, 0.55; 95% confidence interval, 0.36 to 0.87; P=0.01). Among patients who had a response to R-CHOP, maintenance therapy with rituximab significantly improved overall survival (4-year survival rate, 87%, vs. 63% with interferon alfa; P=0.005).

CONCLUSIONS

R-CHOP induction followed by maintenance therapy with rituximab is effective for older patients with mantle-cell lymphoma. (Funded by the European Commission and others; ClinicalTrials.gov number, NCT00209209.).
