Dietary Patterns and Socioeconomic Status in the Very Old: The Newcastle 85+ Study.

ABSTRACT:

Background

Dietary patterns (DP) are associated with health outcomes in younger adults but there is a lack of evidence in the very old (aged 85+) on DP and their association with sociodemographic factors, lifestyle, health and functioning measures. Higher socioeconomic status (SES) has been linked with healthier DP but it is not known whether these associations are sustained in the very old.

Objective

We aimed to (a) characterise DP in the very old and (b) assess the relationships between three SES indicators (education, occupational class and area-deprivation index [IMD]) and DP.

Methods

Complete dietary data at baseline (2006/07) for 793 participants in the Newcastle 85+ Study were established through 24-hr multiple pass recall. We used Two-Step clustering and 30 food groups to derive DP, and multinomial logistic regression models to assess the association with SES.

Results

We identified three distinct DP (characterised as 'High Red Meat', 'Low Meat', and 'High Butter') that varied with key sociodemographic, health and functioning measures. 'Low Meat' participants were more advantaged (i.e. higher education and occupational class, and lived in more affluent areas in owned homes), were least disabled, cognitively impaired, and depressed, and were more physically active than those in the other DP. After adjusting for other lifestyle factors, cognitive status and BMI, lower educational attainment remained a significant predictor of 'High Red Meat' and 'High Butter' membership compared with 'Low Meat' ('High Red Meat': OR [95% CI] for 0-9 and 10-11 years of education vs. ?12 years: 5.28 [2.85-9.79], p<0.001 and 3.27 [1.65-6.51], p = 0.001, respectively; 'High Butter': 3.32 [1.89-5.82], p<0.001 and 2.83 [1.52-5.28], p = 0.001).

Conclusions

In this cohort of very old adults, we detected a favourable DP ('Low Meat'), which was associated with better health and functioning and higher SES.

Project description:BACKGROUND:Sarcopenia, a progressive age-related loss of skeletal muscle mass and strength, leads to disability, falls, and hospitalisation. Individual variation in sarcopenia onset may be partly explained by lifestyle factors such as physical activity and diet. Healthy dietary patterns (DPs) have been linked to better physical functioning in older adults, but their role in sarcopenia in the very old (aged ?85) is unknown. AIMS:To investigate the association between DPs and the risk of sarcopenia over 3 years, and to determine whether protein intake influences this relationship in community-dwelling older adults from the Newcastle 85 + Study. METHODS:The analytic sample consisted of 757 participants (61.2% women) who had dietary assessment at baseline. After two-step clustering with 30 food groups to derive DPs, we used logistic regression to determine the risk of prevalent and incident sarcopenia across DPs in all participants, and in those with low (<1 g/kg adjusted body weight/day [g/kg aBW/d]) and good protein intake (?1 g/kg aBW/d). RESULTS:We identified three DPs (DP1: 'Low Red Meat', DP2: 'Traditional British' and DP3: 'Low Butter') that varied by unsaturated fat spreads/oils, butter, red meat, gravy and potato consumption. Compared with participants in DP3, those in DP2 had an increased risk of prevalent (OR = 2.42, 95% CI: 1.15-5.09, p = 0.02) but not 3-year incident sarcopenia (OR = 1.67, 0.59-4.67, p = 0.33) adjusted for socio-demographic, anthropometry, health and lifestyle factors. Furthermore, DP2 was associated with an increased risk of prevalent sarcopenia at baseline (OR = 2.14, 1.01-4.53, p = 0.05) and 3-year follow-up (OR = 5.45, 1.81-16.39, p = 0.003) after adjustment for key covariates in participants with good protein intake. CONCLUSION:A DP high in foods characteristic of a traditional British diet (butter, red meat, gravy and potato) was associated with an increased risk of sarcopenia even when overall protein intake was good. The results need to be replicated in other cohorts of the very old to understand the role of DPs in sarcopenia onset and management.
