Older people and internet engagement: acknowledging social moderators of internet adoption, access and use

– This paper seeks to describe a deep investigation of the phenomenon of internet engagement amongst older people. The likelihood of internet engagement has been shown in previous work to rapidly decrease with age, and patterns of disengagement are most pronounced amongst older people., – The study comprises a qualitative investigation consisting of observation and interviews conducted within a programme of internet literacy workshops funded by the Welsh Assembly Government., – The reflection of previous research with data collected has led to the development of a model of older peoples internet engagement. This model helps us better understand the context for patterns of engagement and disengagement with the internet., – The model of internet engagement is used to highlight a number of strategies that should be considered in future policy intervention in the area of digital inclusion., – The model described offers a more sophisticated instrument for understanding the issue of the digital divide amongst this excluded group and potentially may be applied more generally in understanding the complex nature of this issue.

Obesity in pregnancy: a retrospective prevalence-based study on health service utilisation and costs on the NHS.

Objective To estimate the direct healthcare cost of being overweight or obese throughout pregnancy to the National Health Service in Wales. Design Retrospective prevalence-based study. Setting Combined linked anonymised electronic datasets gathered on a cohort of women enrolled on the Growing Up in Wales: Environments for Healthy Living (EHL) study. Women were categorised into two groups: normal body mass index (BMI; n=260) and overweight/obese (BMI>25; n=224). Participants 484 singleton pregnancies with available health service records and an antenatal BMI. Primary outcome measure Total health service utilisation (comprising all general practitioner visits and prescribed medications, inpatient admissions and outpatient visits) and direct healthcare costs for providing these services in the year 2011–2012. Costs are calculated as cost of mother (no infant costs are included) and are related to health service usage throughout pregnancy and 2 months following delivery. Results There was a strong association between healthcare usage cost and BMI (p<0.001). Adjusting for maternal age, parity, ethnicity and comorbidity, mean total costs were 23% higher among overweight women (rate ratios (RR) 1.23, 95% CI 1.230 to 1.233) and 37% higher among obese women (RR 1.39, 95% CI 1.38 to 1.39) compared with women with normal weight. Adjusting for smoking, consumption of alcohol, or the presence of any comorbidities did not materially affect the results. The total mean cost estimates were £3546.3 for normal weight, £4244.4 for overweight and £4717.64 for obese women. Conclusions Increased health service usage and healthcare costs during pregnancy are associated with increasing maternal BMI; this was apparent across all health services considered within this study. Interventions costing less than £1171.34 per person could be cost-effective if they reduce healthcare usage among obese pregnant women to levels equivalent to that of normal weight women.

Physical Activity and Excess Weight in Pregnancy Have Independent and Unique Effects on Delivery and Perinatal Outcomes

Background This study examines the effect of low daily physical activity levels and overweight/obesity in pregnancy on delivery and perinatal outcomes. Methods A prospective cohort study combining manually collected postnatal notes with anonymised data linkage. A total of 466 women sampled from the Growing Up in Wales: Environments for Healthy Living study. Women completed a questionnaire and were included in the study if they had an available Body mass index (BMI) (collected at 12 weeks gestation from antenatal records) and/or a physical activity score during pregnancy (7-day Actigraph reading). The full statistical model included the following potential confounding factors: maternal age, parity and smoking status. Main outcome measures included induction rates, duration of labour, mode of delivery, infant health and duration of hospital stay. Findings Mothers with lower physical activity levels were more likely to have an instrumental delivery (including forceps, ventouse and elective and emergency caesarean) in comparison to mothers with higher activity levels (adjusted OR:1.72(95%CI: 1.05 to 2.9)). Overweight/obese mothers were more likely to require an induction (adjusted OR:1.93 (95%CI 1.14 to 3.26), have a macrosomic baby (adjusted OR:1.96 (95%CI 1.08 to 3.56) and a longer hospital stay after delivery (adjusted OR:2.69 (95%CI 1.11 to 6.47). Conclusions The type of delivery was associated with maternal physical activity level and not BMI. Perinatal outcomes (large for gestational age only) were determined by maternal BMI.

Factors associated with low fitness in adolescents – A mixed methods study

BackgroundFitness and physical activity are important for cardiovascular and mental health but activity and fitness levels are declining especially in adolescents and among girls. This study examines clustering of factors associated with low fitness in adolescents in order to best target public health interventions for young people.Methods1147 children were assessed for fitness, had blood samples, anthropometric measures and all data were linked with routine electronic data to examine educational achievement, deprivation and health service usage. Factors associated with fitness were examined using logistic regression, conditional trees and data mining cluster analysis. Focus groups were conducted with children in a deprived school to examine barriers and facilitators to activity for children in a deprived community.ResultsUnfit adolescents are more likely to be deprived, female, have obesity in the family and not achieve in education. There were 3 main clusters for risk of future heart disease/diabetes (high cholesterol/insulin); children at low risk (not obese, fit, achieving in education), children ‘visibly at risk’ (overweight, unfit, many hospital/GP visits) and ‘invisibly at risk’ (unfit but not overweight, failing in academic achievement). Qualitative findings show barriers to physical activity include cost, poor access to activity, lack of core physical literacy skills and limited family support.ConclusionsLow fitness in the non-obese child can reveal a hidden group who have high risk factors for heart disease and diabetes but may not be identified as they are normal weight. In deprived communities low fitness is associated with non-achievement in education but in non-deprived communities low fitness is associated with female gender. Interventions need to target deprived families and schools in deprived areas with community wide campaigns.

Parental recommendations for population level interventions to support infant and family dietary choices: a qualitative study from the Growing Up in Wales, Environments for Healthy Living (EHL) study

BackgroundChildhood obesity presents a challenge to public health. This qualitative study explored the main barriers to dietary choices faced by parents with infants, and the types of interventions and policy level recommendations they would like to see put in place, to promote a healthier food environment.Methods61 semi-structured interviews with prospective parents and parents of infants (61 mothers and 35 fathers) were conducted. Families were selected according to community deprivation levels using the Townsend Deprivation Index to ensure a representative sample from deprived and affluent neighbourhoods. Inductive thematic analysis was used to analyse the data.ResultsParents identified triggers which led to unhealthy dietary choices such as reliance on fast food outlets due to; shift work, lack of access to personal transport, inability to cook, their own childhood dietary experiences, peer pressure and familial relationships. Parents who made healthy dietary choices reported learning cooking skills while at university, attending community cooking classes, having access to quality food provided by church and community organisations or access to Healthy Start vouchers. They called for a reduction in supermarket promotion of unhealthy food and improved access to affordable and high-quality fresh produce in the local area and in supermarkets. There was a strong message to policy makers to work with commercial companies (food manufactures) as they have resources to lower costs and target messages at a diverse population. Provision of targeted advice to fathers, minority ethnic parents, and tailored and practical advice and information on how to purchase, prepare, store and cook food was requested, along with community cookery classes and improved school cookery lessons.ConclusionsThere is a need for parent directed community/population level interventions that aims to reduce socio-ecological barriers to making healthy dietary choices. Parents desired improvements in meals provided in workplaces, schools and hospitals, as well as increased access to healthy foods by increasing local healthy food outlets and reducing unhealthy, fast food outlets. Knowledge and skills could then be enhanced in line with these improvements, with confidence gained around cooking and storing food appropriately.

Mothers' perspectives on the delivery of childhood injury messages: a qualitative study from the growing up in Wales, environments for healthy living study (EHL).

BackgroundChildhood injury is the second leading cause of death for infants aged 1–5 years in the United Kingdom (UK) and most unintentional injuries occur in the home. We explored mothers’ knowledge and awareness of child injury prevention and sought to discover mothers’ views about the best method of designing interventions to deliver appropriate child safety messages to prevent injury in the home.MethodsQualitative study based on 21 semi-structured interviews with prospective mothers and mothers of young children. Mothers were selected according to neighbourhood deprivation status.ResultsThere was no difference in awareness of safety devices according to mothers’ deprivation status. Social networks were important in raising awareness and adherence to child safety advice. Mothers who were recent migrants had not always encountered safety messages or safety equipment commonly used in the UK. Mothers’ recommended that safety information should be basic and concise, and include both written and pictorial information and case studies focus on proactive preventive messages. Messages should be delivered both by mass media and suitably trained individuals and be timed to coincide with pregnancy and repeated at age appropriate stages of child development.ConclusionsThe findings suggest that timely childhood injury-related risk messages should be delivered during pregnancy and in line with developmental milestones of the child, through a range of sources including social networks, mass media, face-to-face advice from health professionals and other suitably trained mothers. In addition information on the safe use of home appliances around children and use of child safety equipment should be targeted specifically at those who have recently migrated to the United Kingdom.

Classification of accelerometer wear and non-wear events in seconds for monitoring free-living physical activity

Objective To classify wear and non-wear time of accelerometer data for accurately quantifying physical activity in public health or population level research. Design A bi-moving-window-based approach was used to combine acceleration and skin temperature data to identify wear and non-wear time events in triaxial accelerometer data that monitor physical activity. Setting Local residents in Swansea, Wales, UK. Participants 50 participants aged under 16 years (n=23) and over 17 years (n=27) were recruited in two phases: phase 1: design of the wear/non-wear algorithm (n=20) and phase 2: validation of the algorithm (n=30). Methods Participants wore a triaxial accelerometer (GeneActiv) against the skin surface on the wrist (adults) or ankle (children). Participants kept a diary to record the timings of wear and non-wear and were asked to ensure that events of wear/non-wear last for a minimum of 15 min. Results The overall sensitivity of the proposed method was 0.94 (95% CI 0.90 to 0.98) and specificity 0.91 (95% CI 0.88 to 0.94). It performed equally well for children compared with adults, and females compared with males. Using surface skin temperature data in combination with acceleration data significantly improved the classification of wear/non-wear time when compared with methods that used acceleration data only (p<0.01). Conclusions Using either accelerometer seismic information or temperature information alone is prone to considerable error. Combining both sources of data can give accurate estimates of non-wear periods thus giving better classification of sedentary behaviour. This method can be used in population studies of physical activity in free-living environments.

Association of Diabetes in Pregnancy with Child Weight at Birth, Age 12 Months and 5 Years – A Population-Based Electronic Cohort Study

Background This study examines the effect of diabetes in pregnancy on offspring weight at birth and ages 1 and 5 years. Methods A population-based electronic cohort study using routinely collected linked healthcare data. Electronic medical records provided maternal diabetes status and offspring weight at birth and ages 1 and 5 years (n = 147,773 mother child pairs). Logistic regression models were used to obtain odds ratios to describe the association between maternal diabetes status and offspring size, adjusted for maternal pre-pregnancy weight, age and smoking status. Findings We identified 1,250 (0.9%) pregnancies with existing diabetes (27.8% with type 1 diabetes), 1,358 with gestational diabetes (0.9%) and 635 (0.4%) who developed diabetes post-pregnancy. Children whose mothers had existing diabetes were less likely to be large at 12 months (OR: 0.7 (95%CI: 0.6, 0.8)) than those without diabetes. Maternal diabetes was associated with high weight at age 5 years in children whose mothers had a high pre-pregnancy weight tertile (gestational diabetes, (OR:2.1 (95%CI:1.25–3.6)), existing diabetes (OR:1.3 (95%CI:1.0 to 1.6)). Conclusion The prevention of childhood obesity should focus on mothers with diabetes with a high maternal pre-pregnancy weight. We found little evidence that diabetes in pregnancy leads to long term obesity ‘programming’.

Obesity in pregnancy: infant health service utilisation and costs on the NHS

Objective To estimate the direct healthcare cost of infants born to overweight or obese mothers to the National Health Service in the UK. Design Retrospective prevalence-based study. Setting Combined linked anonymised electronic data sets on a cohort of mother–child pairs enrolled on the Growing Up in Wales: Environments for Healthy Living (EHL) study. Infants were categorised according to maternal early-pregnancy body mass index (BMI): healthy weight mother (18.5≤BMI<25 kg/m2; n=342), overweight mother (25≤BMI≤29.9 kg/m2; n=157) and obese mother (BMI≥30; n=110). Participants 609 singleton pregnancies with available health service records and an antenatal maternal BMI. Primary outcome measure Total health service utilisation and direct healthcare costs for providing these services in the year 2012–2013. Costs are calculated as cost of the infant (no maternal costs considered) and are related to health service usage from birth to age 1 year. Results A strong association existed between healthcare usage cost and BMI (p<0.001). Mean total costs were 72% higher among children born to obese mothers (rate ratio (RR) 1.72, 95% CI 1.71 to 1.73) compared with infants born to healthy weight mothers. Higher costings were attributed to a significantly greater number (RR 1.39, 95% CI 1.04 to 1.84) and duration (RR 1.55, 95% CI 1.37 to 1.74) of inpatient visits and a higher number of general practitioner visits (RR 1.10, 95% CI 1.03 to 1.16). Total mean additional resource cost was estimated at £65.13 for infants born to overweight mothers and £1138.11 for infants born to obese mothers, when compared with infants of healthy weight mothers. Conclusions Increasingly infants born to mothers with high BMIs consume additional health service resources in the first year of life; this was apparent across inpatient and general practitioner services. Considering both maternal and infant health service use, interventions that cost less than £2310 per person in reducing obesity early pregnancy could be cost-effective.

Evaluating a digital divide index in a regional context

Purpose – The purpose of this research is to show that the provision of an increasing range of remote, electronic access channels by private and public sector bodies is predicated on a critical mass of citizenry utilising such access channels. However, a major concern is that the increasing use of ICT for private and public sector transactions is seen as potentially creating a “digital divide” between those with access to technology and those who do not. This paper adapts an index of the digital divide documented in previous work and utilises this instrument to analyse the depth and breadth of this phenomenon in a UK region – Wales. Design/methodology/approach – The paper discusses the construction of a “digital divide index” (DDIX) for Wales based upon the previous established work of Husing and Selhofer. The DDIX is applied to data collected as part of a major European-wide project – UNDERSTAND. Findings – The DDIX situates four citizen segments in terms of internet access and usage – gender, age, education and income. There are no significant digital divides evident within the Welsh region in terms of gender and income. However, there are significant digital divides in terms of age and education. Research limitations/implications – The DDIX as formulated considers a limited range of possible dimensions, both in terms of citizen groups and internet access and usage. Other possible dimensions for consideration are discussed in the paper. Practical implications – Our application of a DDIX has been useful in highlighting the multi-faceted nature of this phenomenon within a regional context. Further research is required both to refine such an important information society metric and to apply it in further domains of analysis. Originality/value – The paper will be of interest both to academic researchers and policy-makers interested in understanding and measuring the digital divide.
