Changes in diet quality across life transitions from adolescence to early adulthood: a latent growth analysis.

Background: Adolescence to early adulthood is a period of multiple life transitions. These transitions, along with changing resources and contexts, could contribute to significant changes in diet, which may persist into later adulthood.

Objectives: We investigated diet quality trajectories from age 15 to 31 y and changes in diet quality associated with life transitions by sex.

Early adulthood socioeconomic trajectories contribute to inequalities in adult diet quality, independent of childhood and adulthood socioeconomic position.

Background: Diet is an important risk factor for cardiovascular disease and shows well-established socioeconomic patterning among adults. However, less clear is how socioeconomic inequalities in diet develop across the life course. This study assessed the associations of early adulthood socioeconomic trajectories (SETs) with adult diet quality, adjusting for childhood socioeconomic position (SEP) and testing for mediation by adulthood SEP.

Interpersonal determinants of diet quality and eating behaviors in people aged 13-30 years: A systematic scoping review.

Adolescence is an important period of increasing independence, when adolescents experience changing influences of family and friends on their diets as they transition into adulthood. We conducted a scoping review to map the literature on interpersonal determinants of diet quality and eating behaviors among individuals aged 13-30 years. We searched seven literature databases, and following screening, 329 papers were included.

Exploring the changing association between parental and adolescent fruit and vegetable intakes, from age 10 to 30 years.

Background: Adolescence is a pivotal developmental stage, where escalating rates of overweight and obesity have raised concerns about diet quality and its association with adverse health outcomes. Parents are known to have considerable influence on childhood diet, but how this influence changes as adolescents mature is unknown. This study investigates the association between parental fruit and vegetable (FV) intake and adolescent FV consumption, exploring how this changes across adolescence and when adolescents leave home.

Changes in diet quality across life transitions from adolescence to early adulthood: a latent growth analysis.

Background: Adolescence to early adulthood is a period of multiple education-, employment- and family-related life transitions. Changing resources and food environments within the context of these transitions could contribute to significant changes in diet, which persist into later adulthood. This study investigated diet quality trajectories from age 15 to 31 years and changes in diet quality associated with life transitions, by sex.

Total and temporal patterning of physical activity in adolescents and associations with mental wellbeing.

Background: There is limited understanding of the extent to which differences in physical activity across the day and week may be associated with mental wellbeing. Such an understanding is needed for better targeting of interventions. In this study, we describe total and temporal patterning of physical activity across the week in adolescents (age 13-14y) and assess their prospective associations with mental wellbeing.

A longitudinal study of lifestyle behaviours in emerging adulthood and risk for symptoms of depression, anxiety, and stress.

Background: Little research has examined how lifestyle behaviours cluster together to contribute to mental health outcomes. The current study aimed to identify latent classes of emerging adult lifestyle behaviours (diet, physical activity, sedentary time, smoking, alcohol, cannabis, and other drug use) at age 20 years and their associations with depression, anxiety, and stress symptoms at age 22 and 27 years.

Methods: Participants were 616 emerging adults enrolled in the Raine Study.

Shorter sleep among adolescents is associated with lower fruit and vegetable consumption the following day.

Background: Insufficient sleep has been associated with weight gain and metabolic dysregulation, with one suggested mechanism being through reduction in diet quality. Experimental evidence supports a causal effect of sleep timings on diet but this may not be applicable to a free-living adolescent population. In this analysis we use daily measures of sleep timings and diet quality, to examine the effect of sleep duration and timing on diet quality the following day among free-living adolescents.

Recruitment and retention into longitudinal health research from an adolescent perspective: a qualitative study.

Background: High quality longitudinal studies investigating changes in health behaviours over the transition into early adulthood are critical. However, recruiting and retaining adolescents is challenging. This study explored adolescents' perspectives of signing up to and continuing involvement in a hypothetical longitudinal health research study.

Device-measured sleep onset and duration in the development of depressive symptoms in adolescence.

Background: Sleep deprivation in adolescence is increasing in prevalence and may be linked to subsequent depression. Findings regarding associations between sleep duration, sleep onset time, and the development of depressive symptoms over time in adolescents are mixed, and rely on subjective measures of sleep.

Methods: Sleep onset and duration were assessed using a combined heart rate monitor and accelerometer and self-report in 688 participants from the ROOTS study at age 15.

Early adulthood socioeconomic trajectories contribute to inequalities in adult cardiovascular health, independently of childhood and adulthood socioeconomic position.

Background: Cardiovascular health shows significant socioeconomic inequalities, however there is little understanding of the role of early adulthood in generation of these inequalities. We assessed the contribution of socioeconomic trajectories during early adulthood (16-24 years) to cardiovascular health in mid-adulthood (46 years).

Methods: Participants from the 1970 British Cohort Study with socioeconomic data available in early adulthood were included (n=12 423).

Cohabitation and marriage during the transition between adolescence and emerging adulthood: A systematic review of changes in weight-related outcomes, diet and physical activity.

Our aim was to systematically review the effect of cohabitation and marriage on physical activity, diet and weight-related outcomes during emerging adulthood. A systematic search of six electronic databases was conducted until July 2019 (PROSPERO:CRD42018106943). Prospective studies were included if data were presented for a weight-related outcome, physical activity, and/or diet among 15-35 years-old participants assessed pre- and post-cohabitation or marriage and compared to a consistently non-cohabiting/non-married (single) reference group.

How do associations between sleep duration and metabolic health differ with age in the UK general population?

Background: Despite a growing body of evidence suggesting that short sleep duration may be linked to adverse metabolic outcomes, how these associations differ between age groups remains unclear. We use eight years of data from the UK National Diet and Nutritional Survey (NDNS) (2008-2016) to analyse cross-sectional relationships between sleep duration and metabolic risk in participants aged 11-70 years.

Methods: Participants (n = 2008) who provided both metabolic risk and sleep duration data were included.

Associations of early adulthood life transitions with changes in fast food intake: a latent trajectory analysis.

Background: Early adulthood is a period of rapid personal development when individuals experience major life transitions (e.g. leaving the parental home, leaving education, beginning employment, cohabitation and parenthood).

Cohabiting and becoming a parent: associations with changes in physical activity in the 1970 British cohort study.

Background: We examined the association between family-related life events (cohabitation/marriage and becoming a parent) and change in physical activity.

Methods: Longitudinal data (n = 8045) from the 1970 British Cohort Study (30 and 34 years) were included. Life events (beginning cohabitation/marriage and becoming a parent) were reported and coded: 0 no, 1 yes, for each event occurring between 30 and 34 years.

How do short-term associations between diet quality and metabolic risk vary with age?

Purpose: Poor diet quality is one of the key contributors to poor cardiovascular health and associated morbidity and mortality. This study aimed to assess how the short-term associations between diet quality and metabolic risk factors change with age.

Methods: This longitudinal, observational study used data from the National Diet and Nutrition Survey (2008-2016) (n = 2024).

Becoming a parent: A systematic review and meta-analysis of changes in BMI, diet, and physical activity.

Obesity prevalence rises fastest during young adulthood when weight, diet, and physical activity may be influenced by life events, including becoming a parent, but the impact is uncertain. We searched six electronic databases to July 2019 for longitudinal studies (both sexes) aged 15 to 35 years with a prospective pre-pregnancy/parenthood and post-delivery outcome. Of 11 studies (across 15 papers), six studies (women only) were eligible for meta-analysis of the difference in change in body mass index (BMI; kg/m ) between remaining without children and becoming a parent.

Changes in physical activity, diet, and body weight across the education and employment transitions of early adulthood: A systematic review and meta-analysis.

Early adulthood is a time when individuals go through important life transitions, such as moving from high school into higher education or employment, but the impact of these life transitions on changes in body weight, diet, and physical activity is not known. We searched six electronic databases to July 2019 for longitudinal observational studies providing data on adiposity, diet, and/or physical activity across education or employment transitions in young people aged between 15 and 35 years. We found 19 studies, of which 17 assessed changes in physical activity, three body weight, and five diet or eating behaviours.

Diet Quality through Adolescence and Early Adulthood: Cross-Sectional Associations of the Dietary Approaches to Stop Hypertension Diet Index and Component Food Groups with Age.

Late adolescence to early adulthood is the period of life when prevalence of overweight and obesity rises the fastest, and an important time to understand changes in dietary risk factors. In this study we assess the variation in diet quality through analysis of cross-sectional data from 2957 individuals aged 13 to 30 from the National Diet and Nutrition Study (2008⁻2016). Diet data were self-reported using four-day food diaries and coded to give diet quality using the dietary approaches to stop hypertension (DASH) index (range 0⁻80) and DASH component food groups (grams/day).

Changes in diet through adolescence and early adulthood: longitudinal trajectories and association with key life transitions.

Background: Early adulthood is a period associated with poor diet and rapid weight gain. This is also an age of transition, including environmental, social and lifestyle changes which may be associated with changes in diet. We assess longitudinal associations between four early adulthood life transitions (leaving home, leaving education, entering employment, and cohabitation) and changes in consumption of fruit, vegetables, confectionery and sugar-sweetened beverages (SSBs).

Diet quality and depressive symptoms in adolescence: no cross-sectional or prospective associations following adjustment for covariates.

Objective: Adolescence is a critical period for development of depression and understanding of behavioural risk factors is needed to support appropriate preventive strategies. We examined associations between adolescent diet quality and depressive symptoms, cross-sectionally and prospectively, in a large community cohort, adjusting for behavioural and psychosocial covariates.

Design: Prospective community-based cohort study (ROOTS).

Current and future cardiovascular disease risk assessment in the European Union: an international comparative study.

Background: Risk assessment is central to primary prevention of cardiovascular disease (CVD), but there remains a need to better understand the use of evidence-based interventions in practice. This study examines: (i) the policies and guidelines for risk assessment in Europe, (ii) the use of risk assessment tools in clinical practice and (iii) the barriers to, and facilitators of, risk assessment.

Methods: Data were collected from academics, clinicians and policymakers in an online questionnaire targeted at experts from all European Union member states, and in 8 in-depth country case studies that were developed from a targeted literature review and 36 interviews.

Changes in diet from age 10 to 14 years and prospective associations with school lunch choice.

Background: There is limited evidence on how diet changes over the transition from primary to secondary school. In this study we investigated changes in diet from age 10 (2007) to age 14 years (2011) and the contribution of school-time consumption and school lunch choice to such changes.

Methods: The 351 participants with dietary data (4 day food record) available at baseline (age 10 years) and follow-up (age 14 years) were included.

Change in diet in the period from adolescence to early adulthood: a systematic scoping review of longitudinal studies.

Background: Late adolescence to early adulthood is a period of lifestyle change and personal development which may influence dietary behaviour. Understanding dietary trajectories across this age range may help in targeting interventions appropriately. This scoping review aimed to assess how longitudinal change in diet is conceptualised and measured between the ages of 13 to 30.

Community Hospitals in Selected High Income Countries: A Scoping Review of Approaches and Models.

Background: There is no single definition of a community hospital in the UK, despite its long history. We sought to understand the nature and scope of service provision in community hospitals, within the UK and other high-income countries.

Methods: We undertook a scoping review of literature on community hospitals published from 2005 to 2014.
