The association between nutrient intake, nutritional status and physical function of community-dwelling ethnically diverse older adults

Abstract Background: There are limited longitudinal data regarding nutrient intake, nutritional status and physical function in community-dwelling ethnically diverse older adults. This study explored these variables and their relationship at baseline (n=100) and 8-months’ follow-up (n=81) among community-dwelling ethnically diverse older adults (≥60 years) in Birmingham, United Kingdom. Methods: Multiple-pass 24-hour dietary recalls and the Mini Nutritional Assessment-Short Form assessed nutritional intake and status, respectively. Short Physical Performance Battery (SPPB) and handgrip strength measured physical function. Linear and multinomial regressions were used to predict relationships between physical function, nutritional status and nutrient intake. Results: Complete data were collected at baseline (n=100) and 8-months’ follow-up (n=81). Mean (SD) age was 70 (8.1) years (60% male), with 62% being obese. Statistically significant decreases in intakes of vitamin B6, vitamin B1, iron, folate, and magnesium occurred over time. Daily intake of all micronutrients except vitamin B12, phosphorus and manganese were below the Recommended Nutrient Intakes (RNI). SPPB (Z=-4.01, p<0.001) and nutritional status (Z=-2.37, p=0.018) declined over time. Higher SPPB scores at baseline (OR=0.54 95% CI 0.35, 0.81) were associated with a slower decline in nutritional status. Conclusion: The observed declines and inadequate nutrient intakes in the absence of weight loss in just eight months may pose serious challenges to healthy ageing, identifying an urgent need to re-evaluate and tailor appropriate dietary advice for this population. Additionally, the associations of nutrition and physical function observed in this study serves as an essential resource to design and implement community/faith-based interventions targeting early screening of nutritional status and physical function to ensure most older adults are assessed and treated accordingly.

Abstract There are limited longitudinal data regarding nutritional intake and status, and physical function in community-dwelling ethnically diverse older adults. This study explored these variables and their relationship at baseline (n=100) and after 8-months (n=81) among community-dwelling ethnically diverse older adults (≥60 years) in Birmingham, United Kingdom. Multiple pass 24-hour dietary recalls and the Mini Nutritional Assessment-Short Form assessed nutritional intake and status, respectively. The Short Physical Performance Battery(SPPB) and handgrip strength measured physical function. Linear and multinomial regression analyses were used to predict the relationship between nutritional intake, status and physical function. Mean(SD) age was 70(8.1) years (60% male), with 62% of the sample being obese. Significant decreases in intakes of vitamin B6(0.88-0.77mg/day, p=0.014); vitamin B1(0.73-0.63mg/day, p=0.029); iron(6.16-5.85mg/d, p=0.045); folate(113.23-106.66µg/d, p=0.043); and magnesium(154.54-144.59mg/d, p=0.031) occurred over time. At both timepoints, across sexes, daily intakes of all micronutrients except vitamin B12, phosphorus and manganese were below the Recommended Nutrient Intakes. There were significant declines in SPPB scores(Z=-4.01, p<0.001) and nutritional status(Z=-2.37,p=0.018) over time. At baseline, younger age, better nutritional status, and higher vitamin D and fibre intakes were associated with higher SPPB scores. At follow-up, higher baseline SPPB scores (OR=0.54 95% CI:0.35, 0.81) were associated with reduced decline in nutritional status. The observed declines in nutritional status and physical function, and the inadequate nutrient intakes in the absence of weight loss within eight months pose serious challenges to healthy ageing. There is an urgent need to re-evaluate and tailor appropriate dietary advice for this population to support them to age healthily.

Lifestyle Practices

Ethnic minorities have a high prevalence of non-communicable diseases relating to unhealthy lifestyle practices. Several factors have been identified as influencing unhealthy lifestyle practices among this population; however, there is little evidence about how these factors differ among a heterogeneous sample living in a super-diverse city. This study aimed to: (1) identify and compare factors influencing eating behaviours and physical function among ethnic older minorities living in Birmingham, United Kingdom; and (2) understand how these factors and their association with healthy eating and physical function changed over 8-months. An in-depth interviewing approach was used at baseline (n = 92) and after 8-months (n = 81). Interviews were transcribed verbatim and analysed using directed content analysis. Healthy eating was viewed as more important than, and unrelated to, physical function. Personal, social and cultural/environmental factors were identified as the main factors influencing eating behaviours and physical function, which differed by ethnicity, age, and sex. At 8-month interviews, more men than women reported adverse changes. The study provides unique and useful insights regarding perceived eating behaviours and physical function in a relatively large and diverse sample of older adults that can be used to design new, and adapt existing, culturally-tailored community interventions to support healthy ageing.

Abstract Background The effects of group exercise on the physical function of community-dwelling older adults remain unclear. The changes in lower extremity muscle strength, timed up and go (TUG) time, and the motor fitness scale (MFS), over time, among older adults who expressed a willingness to participate in community-based physical exercise groups, were determined using multilevel modelling. Methods We analyzed data of 2407 older adults between April 2010 and December 2019 from the registry of physical tests of community-based physical exercise groups. We conducted a retrospective cohort study to assess the effect of physical exercise on lower extremity muscle strength, TUG time, and MFS scores. The durations of the exercises were evaluated by frequency of physical test’s participate. Results A deterioration in lower extremity muscle strength was found in the short-term participant group only. However, in the mid-term and long-term participation groups, lower extremity muscle strength showed a trend of improvement. The TUG time and the MFS score were negatively correlated with increasing age in both groups divided by the duration of participation. However, there was a slower rate of deterioration in the long-term participation group. Discussion Lower extremity muscle strength, TUG time, and MFS scores decline with increasing age and there were differences in the slope of deterioration that depended on the duration of participation in community-based group exercise. Conclusion Participation in group exercise improved lower extremity muscle strength, TUG time, and MFS scores of older adults living in a community. The positive effects of group exercise were dependent on long-term participation.
