Diet Quality and Bone Measurements Using HRpQCT and pQCT in Older Community-Dwelling Adults from the Hertfordshire Cohort Study.

ABSTRACT: There are few data describing associations between dietary patterns and bone microarchitecture. This study investigated the relationship between diet quality and HRpQCT and pQCT measures in older adults. Data were available for 184 men and 166 women. Dietary data were collected at baseline (1998-2003) using an administered food frequency questionnaire. A 'prudent' diet score (PDS) was identified using principal component analysis and used as an indicator of dietary quality. HRpQCT and pQCT images were acquired at follow-up in 2012, from the non-dominant distal radius and tibia using Scanco XtremeCT and Stratec XCT2000 instrument scanners, respectively. The mean (SD) PDS was - 0.24 (1.23) for men and 0.62 (1.14) for women. In women, a significant positive relationship was found between baseline dietary pattern and total and trabecular area at both the radius and the tibia, measured by HRpQCT. Similar trends were observed with pQCT parameters. Positive associations were observed for tibia total area (38% slice). At the radius, significant positive associations were found for total area (4% slice) and polar strength strain index (33% slice). All relationships remained robust to adjustment. For men, although patterns were similar, there were no significant associations for HRpQCT outcomes. Significant associations were observed for baseline PDS and polar strength strain and total area (66% slice) at the radius, measured by pQCT. Our data suggest that diets high in fruit, vegetables, oily fish and whole grain cereals in early old age are associated with greater bone size but not volumetric bone density or microarchitecture in later life in women.

Project description:ObjectiveThis analysis examined whether specific social, physical, and financial factors were associated with diet quality among older, community-dwelling women.MethodsThis cross-sectional analysis was conducted in a subset of 6,094 community-dwelling Women's Health Initiative participants who completed a food frequency questionnaire, administered from 2012 to 2013, and a self-administered supplemental questionnaire, administered approximately 1 year later. The supplemental questionnaire included five questions assessing social, physical, and financial factors related to eating. Diet quality was assessed with the Healthy Eating Index-2010 (HEI-2010; range of 0-100; higher score indicates a higher quality diet). The total HEI-2010 score was calculated by summing individual scores representing the intake of nine adequacy components (beneficial food groups) and three moderation components (food groups to limit). Associations of responses to the five questions on the supplemental questionnaire with HEI-2010 scores were examined with multiple linear regression, adjusting for relevant covariates.ResultsMean ± standard deviation age of participants was 78.8 ± 6.7 years. Reporting eating fewer than two meals per day, having dental or other mouth problems causing problems with eating, and not always being able to shop, cook, or feed oneself were associated with statistically significantly lower HEI-2010 scores, compared with those not reporting these issues, after multivariable adjustment: 5.37, 2.98, and 2.39 lower scores, respectively (all P values <0.0001). Reporting eating alone most of the time and not always having enough money to buy food were not associated with HEI-2010 scores.ConclusionsAmong older, community-dwelling women, eating fewer than two meals per day, dental and other mouth problems, and diminished ability to shop for food, prepare meals, and feed oneself were associated with lower diet quality. These are potential targets for interventions to improve diet quality in older women. : Video Summary:http://links.lww.com/MENO/A561.

Project description:We investigated cross-sectional and longitudinal associations of diet quality with middle-aged caregiver status. Caregiving in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study (57.7% women, 62% African American (AA)) was measured at waves 3 (2009-2013) and 4 (2013-2017) (mean follow-up time 4.1 years). Diet quality was assessed by the Healthy Eating Index 2010 (HEI-2010) derived from two separate 24 h diet recalls. Multivariable ordinary least square regression was performed for cross-sectional analyses of the association of wave 4 caregiving with wave 4 HEI-2010. Wave 3 caregiving was examined both cross-sectionally and with annual rate of change in HEI using mixed-effects linear regression Models. Multivariable models were adjusted for age, sex, and poverty status. Cross-sectional analyses at wave 4 demonstrate an inverse association of frequent caregiving ("Daily or Weekly" vs. "Never") for grandchildren with HEI-2010 total score (i.e., lower diet quality) among Whites (β = -2.83 ± 1.19, p = 0.03, Model 2) and AAs (β = -1.84 ± 0.79, p = 0.02,). The "cross-sectional" analysis pertaining to grandchildren caregiving frequency suggested that frequent caregiving (i.e., "Daily or Weekly" vs. "Never" (β = -2.90 ± 1.17, p = 0.04)) only among Whites was inversely related to HEI-2010 total score. Total HEI-2010 score was also related to caring (Model 1), for the elderly over "5 years vs. Never" among Whites (-7.31 ± 3.54, p = 0.04, Model 2). Longitudinally, we found slight potential improvement in diet quality over time ("Daily or Weekly" vs. Never by TIME interaction: +0.88 ± 0.38, p = 0.02) with frequent caregiving among Whites, but not so among AAs. Frequent caring for grandchildren had an inverse relationship with the diet quality of White and AA urban middle-aged caregivers, while caring for elderly was inversely linked to diet quality among Whites only. Longitudinal studies should address the paucity of research on caregivers' nutritional quality.

Project description:BackgroundThe health benefits of physical activity (PA) participation in later life are widely recognised. Understanding factors that can influence the participation of community-dwelling older adults in PA is crucial in an ageing society. This will be paramount in aiding the design of future interventions to effectively promote PA in this population. The main aim of this qualitative study was to explore influences on PA among community-dwelling older people, and the secondary aim was to explore gender differences.MethodsQualitative data were collected in 2014 by conducting focus group discussions using a semi-structured discussion guide with older people resident in Hertfordshire, UK. Discussions were audio-recorded, transcribed verbatim and transcripts analysed thematically.ResultsNinety-two participants were recruited to the study (47% women; 74-83 years) and a total of 11 focus groups were conducted. Findings indicated six themes that appeared to affect older adults' participation in PA: past life experiences; significant life events; getting older; PA environment; psychological/personal factors; and social capital. Overall, the findings emphasised the role of modifiable factors, namely psychological factors (such as self-efficacy, motivation, outcome expectancy) and social factors (such as social support and social engagement). These factors exerted their own influence on physical activity participation, but also appeared to mediate the effect of other largely non-modifiable background and ageing-related factors on participants' engagement with PA in later life.ConclusionIn view of these findings, intervention designers could usefully work with behavioural scientists for insight as to how to enhance psychological and social factors in older adults. Our data suggest that interventions that aim to build self-efficacy, motivation and social networks have the potential to indirectly promote PA participation in older adults. This would be best achieved by developing physical activity interventions through working with participants in an empowering and engaging way.

Project description:BackgroundOlder adults have been especially vulnerable to adverse effects from the COVID-19 pandemic including higher mortality and more severe disease complications. At the same time, social isolation, malnutrition and physical inactivity are serious concerns among older adults. The pandemic and associated restrictions may serve to exacerbate these issues, presenting increased risks to physical and mental health. The aims of this qualitative study were: i) to explore how community-living older people in the UK experienced the first wave of the COVID-19 pandemic, specifically how it impacted their well-being and associated health behaviours; ii) to explore how older people's experiences and behaviours changed over time throughout the first wave.MethodsQualitative data were collected by conducting serial telephone interviews, with an interval of approximately three months. Participants were from the Hertfordshire Cohort Study, all aged over 80 years. Discussions were audio-recorded, information related to the COVID-19 pandemic was transcribed verbatim and transcripts analysed thematically. Interviews were conducted from March to October 2020.ResultsData for twelve participants (7 men and 5 women) from a total of 35 interviews were used, comprising two or three timepoints per participant. Analysis identified five overarching themes: 1) shopping strategies and food accessibility, 2) limitations on activities and going out, 3) disruption to healthcare, 4) social and psychological repercussions, and 5) coping strategies. Findings highlight challenges associated with accessing shops, healthcare, and usual activities due to pandemic-related restrictions. Longitudinal findings showed that for some, the ongoing pandemic and related restrictions appeared to aggravate mental health issues (low mood, anxiety) over time, as well as greater feelings of isolation or loneliness, reduced activity and functional limitations; this was despite some relaxation of restrictions later on. Coping strategies used by participants included finding ways to keep busy and to do physical activity safely, maintaining social contact remotely, and having an optimistic or positive outlook, a 'do what you can' attitude.ConclusionsInterventions are likely to be needed in the wake of the COVID-19 pandemic to support health behaviours, such as increasing physical activity, social engagement and improving mental health among community-living older adults.
