There is increasing interest in modelling longitudinal dietary data and classifying individuals into subgroups (latent classes) who follow similar trajectories over time. These trajectories could identify population groups and time points amenable to dietary interventions. This paper aimed to provide a comparison and overview of two latent class methods: group-based trajectory modelling (GBTM) and growth mixture modelling (GMM). Data from 2963 mother–child dyads from the longitudinal Southampton Women's Survey were analysed. Continuous diet quality indices (DQI) were derived using principal component analysis from interviewer-administered FFQ collected in mothers pre-pregnancy, at 11- and 34-week gestation, and in offspring at 6 and 12 months and 3, 6–7 and 8–9 years. A forward modelling approach from 1 to 6 classes was used to identify the optimal number of DQI latent classes. Models were assessed using the Akaike and Bayesian information criteria, probability of class assignment, ratio of the odds of correct classification, group membership and entropy. Both methods suggested that five classes were optimal, with a strong correlation (Spearman's = 0·98) between class assignment for the two methods. The dietary trajectories were categorised as stable with horizontal lines and were defined as poor (GMM = 4 % and GBTM = 5 %), poor-medium (23 %, 23 %), medium (39 %, 39 %), medium-better (27 %, 28 %) and best (7 %, 6 %). Both GBTM and GMM are suitable for identifying dietary trajectories. GBTM is recommended as it is computationally less intensive, but results could be confirmed using GMM. The stability of the diet quality trajectories from pre-pregnancy underlines the importance of promotion of dietary improvements from preconception onwards. [ABSTRACT FROM AUTHOR]

Ageing in place has been promoted by policy makers as the optimal residential solution for later life, premised on older people's reluctance to contemplate relocation, their declining residential mobility and high levels of residential satisfaction. This paper takes a critical perspective to the notion of ageing in place by examining older people's dislikes about, rather than levels of satisfaction with their home and neighbourhood environments, and establishing whether such dislikes influence a desire to move. Analysis of the 2004 Living in Wales Survey shows that despite high levels of residential satisfaction, a significant proportion of older people do wish to move. Logistic regression results indicate this desire is strongly associated with dislikes about their immediate home environment, more than neighbourhood factors. Contemplating a move in later life may be shaped more by a desire to ‘attach’ to people, than to remain in situ to preserve an attachment to place. [ABSTRACT FROM PUBLISHER]

Background: Developing, elaborating, and consolidating positive views of the self is a plausible route to increased psychological well-being. We set out to provide an assessment of positive self-beliefs that could be used in research and clinical practice. Methods: A non-probability online survey was conducted with 2500 UK adults, quota sampled to match the population for age, gender, ethnicity, income, and region. Exploratory factor analysis of a 94-item pool – generated with guidance from people with lived experience of mental health difficulties – was conducted to develop the Oxford Positive Self Scale (OxPos). The item pool was further reduced using regularised structural equation modelling (SEM) before confirmatory factor analysis. Optimal cut-off scores were developed using receiver operating characteristic curves. Additional validations were carried out with two further general population cohorts (n = 1399; n = 1693). Results: A 24-item scale was developed with an excellent model fit [robust χ2 = 995.676; df = 246; CFI = 0.956; TLI = 0.951; RMSEA = 0.049 (0.047, 0.052); SRMR = 0.031]. The scale comprises four factors: mastery; strength; enjoyment; and character. SEM indicated that the scale explains 68.6% of variance in psychological well-being. The OxPos score was negatively correlated with depression (r = −0.49), anxious avoidance (r = −0.34), paranoia (r = −0.23), hallucinations (r = −0.20), and negative self-beliefs (r = −0.50), and positively correlated with psychological well-being (r = 0.79), self-esteem (r = 0.67), and positive social comparison (r = 0.72). Internal reliability and test–retest reliability were excellent. Cut-offs by age and gender were generated. A short-form was developed, explaining 96% of the full-scale variance. Conclusions: The new open access scale provides a psychometrically robust assessment of positive cognitions that are strongly connected to psychological well-being. [ABSTRACT FROM AUTHOR]

Background: Patient safety is a key priority for healthcare systems. Patient safety huddles have been advocated as a way to improve safety. We explored the feasibility of huddles in general practice. Methods: We invited all general practices in West Yorkshire to complete an online survey and interviewed practice staff. Results: Thirty-four out of 306 practices (11.1%) responded to our survey. Of these, 22 practices (64.7%) reported having breaks for staff to meet and eight (23.5%) reported no longer having breaks in their practices. Seven interviewees identified several barriers to safety huddles including time and current culture; individuals felt meetings or breaks would not be easily integrated into current primary care structure. Discussion: Despite their initial promise, there are major challenges to introducing patient safety huddles within the current context of UK general practice. General practice staff may need more convincing of potential benefits. [ABSTRACT FROM AUTHOR]

In April 2015, the UK introduced Shared Parental Leave (SPL), allowing mothers to transfer their maternity leave to their partners from two weeks after the birth or adoption of a child. There has been very limited research conducted on this leave policy to date and knowledge on take-up is poor. We present findings from an in-depth survey conducted with expectant mothers in two NHS trusts in England on their knowledge, views and plans around leave after the birth of their child and examine variations across educational and ethnic groups. A total of 575 expectant mothers took part in the survey. Around 7.4 per cent of expectant mothers who were (self-)employed or in education intended to take SPL. Finances and worries over fathers' careers were cited as the primary barriers to take up of SPL. Individual entitlement for fathers and knowing others who took SPL increased individuals' reported intention to take SPL. Applying logistic regression models, we found that knowledge of and access to SPL is correlated with education, ethnicity and home ownership. Future research and policy design should attend to such issues to ensure equitable access across families. [ABSTRACT FROM AUTHOR]

Objective: To test whether diets achieving recommendations from the UK's Scientific Advisory Committee on Nutrition (SACN) were associated with higher monetary costs in a nationally representative sample of UK adults.Design: A cross-sectional study linking 4 d diet diaries in the National Diet and Nutrition Survey (NDNS) to contemporaneous food price data from a market research firm. The monetary cost of diets was assessed in relation to whether or not they met eight food- and nutrient-based recommendations from SACN. Regression models adjusted for potential confounding factors. The primary outcome measure was individual dietary cost per day and per 2000 kcal (8368 kJ).Setting: UK.Subjects: Adults (n 2045) sampled between 2008 and 2012 in the NDNS.Results: On an isoenergetic basis, diets that met the recommendations for fruit and vegetables, oily fish, non-milk extrinsic sugars, fat, saturated fat and salt were estimated to be between 3 and 17 % more expensive. Diets meeting the recommendation for red and processed meats were 4 % less expensive, while meeting the recommendation for fibre was cost-neutral. Meeting multiple targets was also associated with higher costs; on average, diets meeting six or more SACN recommendations were estimated to be 29 % more costly than isoenergetic diets that met no recommendations.Conclusions: Food costs may be a population-level barrier limiting the adoption of dietary recommendations in the UK. Future research should focus on identifying systems- and individual-level strategies to enable consumers achieve dietary recommendations without increasing food costs. Such strategies may improve the uptake of healthy eating in the population. [ABSTRACT FROM AUTHOR]
