Increasing stair climbing in a train station: effects of contextual variables and visibility

Accumulation of physical activity during daily living is a current public health target that is influenced by the layout of the built environment. This study reports how the layout of the environment may influence responsiveness to an intervention. Pedestrian choices (n = 41 717) between stairs and the adjacent escalators were monitored for seven weeks in a train station (Birmingham, UK). After a 3.5 week baseline period, a stair riser banner intervention to increase stair climbing was installed on two staircases adjacent to escalators and monitoring continued for a further 3.5 weeks. Logistic regression analyses revealed that the visibility of the intervention, defined as the area of visibility in the horizontal plane opposite to the direction of travel (termed the isovist) had a major effect on success of the intervention. Only the largest isovist produced an increase in stair climbing (isovist=77.6 m2, OR = 1.10, CIs 1.02-1.19; isovist=40.7 m2, OR = 0.98, CIs 0.91-1.06; isovist=53.2 m2, OR = 1.00, CIs 0.95-1.06). Additionally, stair climbing was more common during the morning rush hour (OR = 1.56, CIs 1.80-2.59) and at higher levels of pedestrian traffic volume (OR = 1.92, CIs 1.68-2.21). The layout of the intervention site can influence responsiveness to point-of-choice interventions. Changes to the design of train stations may maximize the choice of the stairs at the expense of the escalator by pedestrians leaving the station

Promoting healthy eating in pregnancy: What kind of support services do women say they want?

Aim: To identify characteristics of the services and support women want to enable them to eat healthily during pregnancy to make a potential future service acceptable to this population. Background: An unhealthy diet during pregnancy may have a significant influence on pregnancy outcome, either directly through nutrient deficiencies or indirectly through maternal weight gain. Many pregnant women in the United Kingdom gain too much weight in pregnancy, and this weight gain may lead to an increased risk of preeclampsia, gestational diabetes and having an obese child. Thus, there is a need for interventions aimed at improving healthy eating in pregnancy. It is crucial in developing successful interventions to understand how participation can be maximised by optimising intervention acceptability. Methods: Four focus groups were conducted; two with prenatal women (n = 9) and two with postnatal women (n = 14). Discussion focused on identifying relevant characteristics of a service targeting prenatal and postnatal women's eating to ensure that a future service was acceptable to the women. Findings: The participants’ responses were clustered into three broad themes: (1) early information leading to routine formation of healthier eating habits, (2) the delivery of practical sessions to increase information and (3) health professionals providing support and signposting to services. The participants reported wanting a practical service held in a convenient location, preferably led by women who have been pregnant themselves. The participants also reported wanting to be offered this service in pregnancy to help them get into a routine before they gave birth. Several suggestions for how this service should be marketed were mentioned, including through midwives and the internet. This research provides practical information for how to design support for prenatal women to increase their knowledge and practical skills regarding eating healthily during their pregnancy

In search of the ‘like-minded’ people: pregnant women’s sense-making of their physical activity-related social experiences

Aims/Background: Social factors are increasingly recognised as influential on antenatal physical activity. While pregnant women describe the people and support they require to remain physically active, little is known about how pregnant women select and make sense of their social experiences throughout pregnancy. This study followed pregnant women’s sense-making of their physical activity-related social experiences as pregnancy progressed, and physical activity declined. Design/Methods: This study used a qualitative design. Four pregnant women were recruited in their second trimester, participated in three individual semi-structured interviews and submitted diary entries throughout trimesters two and three. Data were analysed using longitudinal interpretative phenomenological analysis. Results: To facilitate physical activity, pregnant women were ‘searching for the “like-minded” people who motivate, share and understand’, namely pregnant women and prenatally trained exercise professionals. When making sense of social experiences, pregnant women were ‘grading and critiquing the quality and paucity of “active pregnancy” information’, and‘cherry-picking social experiences necessary for “nesting”, obtaining support and protecting self-esteem as physical activity declined’. This involved disengaging from social experiences, and consequently, some pregnant women found themselves ‘lamenting interactions with the “like-minded” people, contending with grief and inner conflict’. Conclusion: Pregnant women proactively seek and make sense of social experiences to facilitate physical activity. In an increasingly digitalised society, interventions should support pregnant women to utilise social media constructively and safely to access ‘like-minded’ people, provide in-person and virtual networks to meet individual support needs throughout pregnancy and encourage health professionals to demonstrate interest in the ‘active pregnancy’ to maximise influence

Midwives' experiences of referring obese women to either a community or home-based antenatal weight management service:Implications for service providers and midwifery practice

Objective a variety of services to support women to undertake weight management behaviours during pregnancy have recently been implemented as a means to reduce the risks to mother and infant. In the UK, midwives lead the care of the majority of pregnant women and are seen as the ideal source of referral into antenatal services. However, midwives have reported concerns regarding raising the topic of weight with obese women and negative referral experiences have been cited as a reason not to engage with a service. This study explored midwives’ experiences of referring women to one of two antenatal weight management services. Design qualitative, cross-sectional interview and focus group study, with data analysed thematically. Setting midwifery teams in the West Midlands, England. Participants midwives responsible for referring to either a home-based, one to one service (N=12), or a community-based, group service (N=11). Findings four themes emerged from the data. Participants generally had a positive View of the service, but their Information needs were not fully met, as they wanted more detail about the service and feedback regarding the women they had referred. Approaches to referral differed, with some participants referring all women who met the eligibility criteria, and some offering women a choice to be referred or not. Occasionally the topic was not raised at all when a negative reception was anticipated. Reasons for poor uptake of the services included pragmatic barriers, and their perception of women's lack of interest in weight management. Key conclusions midwives’ differing views on choice and gaining agreement to refer means referral practices vary, which could increase the risk that obese women have inequitable access to weight management services. However, midwives’ confidence in the services on offer may be increased with more detailed information about the service and feedback on referrals, which would additionally act as prompts to refer. Implications for practice weight management services need to improve communication with their referral agents and try to overcome practical and psychosocial barriers to uptake. It would be beneficial to develop a shared understanding of the concept of ‘informed choice’ specifically regarding referral to health promotion services among midwives. Training which demonstrates effective methods of sensitively introducing a weight management service to obese women may increase midwives’ confidence to consistently include this in their practice. These measures may improve women's engagement with services which have the potential to reduce the risks associated with maternal obesity

Elevator availability and its impact on stair use in a workplace

Consistent success in encouraging stair climbing on public access staircases contrasts with equivocal evidence for effectiveness in worksites. This paper tests whether contextual factors may affect stair/elevator choice. The study investigated the impact of elevator availability, pedestrian traffic (number using the elevator and stairs per minute), building occupancy (total individuals in the building) and time of day on stair ascent and descent in a workplace. Stair and elevator choices were monitored by automatic counters every weekday during two phases. In a natural experiment, days with four available elevators were compared with days when three elevators were available. Stair use increased for three elevators compared to four. Increasing building occupancy was associated with increased stair use, whilst increasing pedestrian traffic and time of day was associated with reduced stair use. A follow-up study revealed complimentary effects of building occupancy and time of day on elevator waiting times, indicating that increased stair use by contextual factors reflects increased elevator waiting times. In contrast, shorter waiting times are likely when momentary pedestrian traffic is high and later in the day. Crucially, the magnitude of the effects of these contextual factors was ten times larger than previously reported effects of stair climbing interventions

Adopting a healthy lifestyle when pregnant and obese - an interview study three years after childbirth

Background: Obesity during pregnancy is increasing and is related to life-threatening and ill-health conditions in both mother and child. Initiating and maintaining a healthy lifestyle when pregnant with body mass index (BMI) ≥ 30 kg/m2 can improve health and decrease risks during pregnancy and of long-term illness for the mother and the child. To minimise gestational weight gain women with BMI ≥ 30 kg/m2 in early pregnancy were invited to a lifestyle intervention including advice and support on diet and physical activity in Gothenburg, Sweden. The aim of this study was to explore the experiences of women with BMI ≥ 30 kg/m2 regarding minimising their gestational weight gain, and to assess how health professionals' care approaches are reflected in the women's narratives. Methods: Semi-structured interviews were conducted with 17 women who had participated in a lifestyle intervention for women with BMI ≥ 30 kg/m2 during pregnancy 3 years earlier. The interviews were digitally recorded and transcribed in full. Thematic analysis was used. Results: The meaning of changing lifestyle for minimising weight gain and of the professional's care approaches is described in four themes: the child as the main motivation for making healthy changes; a need to be seen and supported on own terms to establish healthy routines; being able to manage healthy activities and own weight; and need for additional support to maintain a healthy lifestyle. Conclusions: To support women with BMI ≥ 30 kg/m2 to make healthy lifestyle changes and limit weight gain during pregnancy antenatal health care providers should 1) address women's weight in a non-judgmental way using BMI, and provide accurate and appropriate information about the benefits of limited gestational weight gain; 2) support the woman on her own terms in a collaborative relationship with the midwife; 3) work in partnership to give the woman the tools to self-manage healthy activities and 4) give continued personal support and monitoring to maintain healthy eating and regular physical activity habits after childbirth involving also the partner and family

Why don't many obese pregnant and post-natal women engage with a weight management service?

Objective: This study investigated the views and experiences of obese pregnant and post-natal women who had declined or disengaged from an evidence-based weight management service, and their reasons for doing so. Background: Despite significant risks of maternal obesity to both mother and baby, the majority of obese women offered tailored weight management support during or after pregnancy declined to use it, and many women who accepted the service disengaged soon after. Methods: Semi-structured interviews regarding women’s views and experiences were conducted with obese pregnant and post-natal women who declined the service (N = 7) and women who disengaged from the service (N = 11) and analysed thematically. Results: Four main themes were identified. ‘First contact counts’ related to inadequate explanation of the service by the referrer, being offended by the referral, and negative expectations of the service. ‘Missed opportunities for support’ describes what support declining women identified as desirable, such as regular weight monitoring. ‘No need for help’, and ‘Service not meeting needs’ related to personal choices regarding weight management, including not wanting support and preferring group-based services. Conclusions: While some obese pregnant and post-natal women did not want any type of weight management support, many did but failed to engage with the service on offer due to a variety of barriers. A more sensitive and transparent referral process and further tailoring of the service to meet individual needs may increase uptake and continued use of this service. The inclusion of non-participants and non-completers formed a valuable element of service evaluation

Women's dietary changes before and during pregnancy: A systematic review

Background: dietary intake before and during pregnancy has significant health outcomes for both mother and child, including a healthy gestational weight gain. To ensure effective interventions are successfully developed to improve dietary intake during pregnancy, it is important to understand what dietary changes pregnant women make without intervention. Aims: to systematically identify and review studies examining women's dietary changes before and during pregnancy and to identify characteristics of the women making these changes. Methods: a systematic search strategy was employed using three databases (Web of Science, CINAHL and PubMed) in May 2016. Search terms included those relating to preconception, pregnancy and diet. All papers were quality assessed using the Scottish Intercollegiate Guidelines Network methodology checklist for cohort studies.The search revealed 898 articles narrowed to full-text review of 23 studies. In total, 11 research articles were included in the review, describing nine different studies. The findings were narratively summarised in line with the aims of the review. Findings: the included studies showed marked heterogeneity, which impacts on the findings. However, the majority report an increase in energy intake (kcal or kJ) during pregnancy. Of the studies that reported changes through food group comparisons, a majority reported a significant increase in fruit and vegetable consumption, a decrease in egg consumption, a decrease in fried and fast food consumption and a decrease in coffee and tea consumption from before to during pregnancy. The characteristics of the women participating in these studies, suggest that age, education and pregnancy intention are associated with healthier dietary changes; however these factors were only assessed in a small number of studies. Key conclusions: the 11 included articles show varied results in dietary intake during pregnancy as compared to before. More research is needed regarding who makes these healthy changes, this includes consistency regarding measurement tools, outcomes and time points. Implications for practice: Midwives as well as intervention developers need to be aware of the dietary changes women may spontaneously engage in when becoming pregnant, so that care and interventions can build on these

Weight management across pregnancy and postpartum care: The need for interprofessional education and collaboration

The journey from pregnancy to caring for a new infant is a significant experience for many women and crucial period for obesity prevention. During this time, a large portion of care is allocated to midwives and maternal and child health nurses (MCHN). These professions have the potential to play a crucial role in supporting women with weight management across pregnancy and postpartum; however, both midwives and MCHNs report barriers to doing this. Upskilling achieved through midwifery and MCHN education that equips midwives and MCHNs with the skills and knowledge to provide evidence-based advice for weight management could assist in addressing some of these barriers. Interprofessional collaboration should be fostered so healthy lifestyle messages and support are reinforced consistently by midwives and MCHNs throughout pregnancy and postpartum
