Nutrient Intake and Factors Influencing Eating Behaviors in Older Migrant Women Living in the United Kingdom

Eating preferences and behaviors of older immigrants in Oslo: A qualitative study

Norway's population of older, first-generation immigrants is expected to almost triple by the year 2060 due to decreased mortality and continued immigration. Studies indicate that older immigrants in Norway have a higher rate of non-communicable disease than older non-immigrants. Eating a health-supporting diet is important for reducing disease risk and maintaining independence in older adults. The purpose of this study was to increase understanding of the eating preferences and behaviors of older, home-dwelling, first-generation immigrants in Oslo, and to identify influences on their eating preferences and behaviors. This qualitative study took a phenomenological approach to understand older immigrants' shared experience of changing eating behaviors with aging. Fourteen home-dwelling, older immigrants were recruited using a combination of purposeful random sampling and snowball sampling. In-depth interviews were conducted then analyzed according to reflexive thematic analysis. Study findings indicate that older immigrants eat a bi-cultural diet pattern. In addition, they seek out information about nutrition, and incorporate many health-supporting eating habits for disease management and prevention. In this way, older immigrants in Oslo share much in common with older non-immigrants. Hopes and worries for the future motivate older immigrants to eat more healthfully in order to maintain independence and cultural identity as long as possible. These results can be useful for designing culturally tailored programs which support eating habits for health maintenance and disease prevention among older immigrants.

Transitioning food environments and diets of African migrants: implications for non-communicable diseases

Non-communicable diseases disproportionately affect African migrants from sub-Saharan Africa living in high-income countries (HICs). Evidence suggests this is largely driven by forces that include migration, globalisation of unhealthy lifestyles (poor diet, physical inactivity and smoking), unhealthy food environments, socio-economic status and population ageing. Changes in lifestyle behaviours that accompany migration are exemplified primarily by shifts in dietary behaviours from more traditional diets to a diet that incorporates that of the host culture, which promotes the development of obesity, diabetes, hypertension and CVD. The current paper presents a critical analysis of dietary change and how this is influenced by the food environment and the socio-economic context following migration. We used a food systems framework to structure the discussion of the interaction of factors across the food system that shape food environments and subsequent dietary changes among African migrant populations living in HICs.

Past, present and future influences of diet among older adults - A scoping review

A tacit understanding of the influence of healthy eating on chronic disease risk and quality of life among older adults is essential for successful design and roll-out of healthy ageing policies. Existing research on dietary determinants among older adults is largely outdated owing to the changing geopolitical scenarios including advancements in health and technology and global migration. Studies published between 2000 and 2020 that explored determinants of diet in older adults were identified using five databases, following Preferred Reporting of Systematic review and Meta-Analyses extended for Scoping Review (PRISMA ScR) guidelines. The final 51 studies (25 quantitative, 22 qualitative and 4 mixed methods) were analysed and interpreted to corroborate existing evidence and identify research gaps. The review identified past influences including childhood affluence and future apprehensions regarding loss of independence and fear of disability to be major drivers of food choices. Current socio-economic status, health conditions and cultural contexts were congruent with past and future influences, implying the role of behavioural change programmes in early life to achieve long term health goals for older adults.

Global Perspective of the Vitamin D Status of African-Caribbean Populations: A Systematic Review and Meta-analysis

BACKGROUND/OBJECTIVES

Vitamin D deficiency remains a global public health issue, particularly in minority ethnic groups. This review investigates the vitamin D status (as measured by 25(OH)D and dietary intake) of the African-Caribbean population globally.

SUBJECTS/METHODS

A systematic review was conducted by searching key databases (PUBMED, Web of Science, Scopus) from inception until October 2019. Search terms included 'Vitamin D status' and 'African-Caribbean'. A random effects and fixed effects meta-analysis was performed by combining means and standard error of the mean.

RESULT

The search yielded 19 papers that included n = 5670 African-Caribbean participants from six countries. A meta-analysis found this population to have sufficient (>50 nmol/L) 25(OH)D levels at 67.8 nmol/L, 95% CI (57.9, 7.6) but poor dietary intake of vitamin D at only 3.0 µg/day, 95% CI (1.67,4.31). For those living at low latitudes 'insufficient' (as defined by study authors) 25(OH)D levels were found only in participants with type 2 diabetes and in those undergoing haemodialysis. Suboptimal dietary vitamin D intake (according to the UK recommended nutrient intake of 10 µg/day) was reported in all studies at high latitudes. Studies at lower latitudes, with lower recommended dietary intakes (Caribbean recommended dietary intake: 2.5 µg/day) found 'sufficient' intake in two out of three studies.

CONCLUSIONS

25(OH)D sufficiency was found in African-Caribbean populations at lower latitudes. However, at higher latitudes, 25(OH)D deficiency and low dietary vitamin D intake was prevalent.

Vitamin D Status of the British African-Caribbean Residents: Analysis of the UK Biobank Cohort

The vitamin D status of the United Kingdom (UK) African-Caribbean (AC) population remains under-researched, despite an increased risk of vitamin D deficiency due to darker skin phenotypes and living at a high latitude. This cross-sectional study explored the vitamin D status and intake of AC individuals (n = 4046 with a valid serum 25(OH)D measurement) from the UK Biobank Cohort, aged ≥40 years at baseline (2006-2010). Over one third of the population were deficient (<25 nmol/L), 41.1% were insufficient (25-50 nmol/L) and 15.9% were sufficient (>50 nmol/L). Median (IQR) 25(OH)D was 30.0 (20.9) nmol/L. Logistic regression showed that brown/black skin phenotype, winter blood draw, not consuming oily fish and not using vitamin D supplements predicted increased odds of vitamin D deficiency, whilst older age and a summer or autumn blood draw were significantly associated with reduced odds of vitamin D deficiency. Vitamin D deficiency and insufficiency were prevalent in this AC population and is of considerable concern given the individual and societal implications of increased morbidity. Public health messaging for this group should focus on year-round vitamin D supplementation and increasing intakes of culturally appropriate vitamin D-rich foods. These data also support the urgent requirement for a revised vitamin D RNI for ethnic groups.

Unpacking the Complexity of Migrated Older Adults' Lives in the UK through an Intersectional Lens: A Qualitative Systematic Review

BACKGROUND AND OBJECTIVES

The intersection of population ageing and international migration increases the ethnic and cultural diversity of the UK's older population, which has significant implications for health and care services and requires social inclusion and equal access to welfare. This review aimed to explore the complexity of migrated older adults' lives and analyse how their multiple identity markers interweave and affect their lived experiences.

RESEARCH DESIGN AND METHODS

This review is a qualitative systematic review. Intersectionality was applied as a theoretical scaffold to inform the qualitative thematic synthesis of the data.

RESULTS

A total of 29 studies in the period 2000-2020 were included. Three themes- language barriers, racism and discrimination, negotiating cultural influences, were identified as common challenges faced by migrated older adults. However, the degree of these challenges and the resources to buffer their effects vary dramatically given the significant differences in older migrated adults' gender, socio-economic status (SES), cultural backgrounds and migration pathways.

DISCUSSION AND IMPLICATIONS

Rather than focusing on any single factor, it is required to consider the intersection of age, race, ethnicity, gender, SES, and migration status when understand and address inequality not only between migrated older adults and native older adults, among different migrated older adult groups but also within any certain group. This review calls for the acknowledgment and awareness of policymakers, care and service practitioners and academics on the heterogeneity of migrated older adults.

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

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-h 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 8 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.

Micronutrient Deficiencies in Medical and Surgical Inpatients

Inpatients are threatened by global malnutrition, but also by specific micronutrient (i.e., trace element and vitamins) deficiencies that frequently are overseen in the differential diagnosis of major organ dysfunctions. Some of them are related to specific geographic risks (iodine, iron, selenium, zinc, vitamin A), while others are pathology related, and finally many are associated with specific feeding patterns, including low dose enteral feeding. Among the pathologies in which laboratory blood investigations should include a micronutrient outwork, anemia is in the front line, followed by obesity with bariatric surgery, chronic liver disease, kidney disease, inflammatory bowel disease, cardiomyopathies and heart failure. The micronutrients at the highest risk are iron, zinc, thiamine, vitamin B12 and vitamin C. Admission to hospital has been linked with an additional risk of malnutrition—feeding below 1500 kcal/day was frequent and has been associated with a structural additional risk of insufficient micronutrient intake to cover basal needs. Although not evidence based, systematic administration of liberal thiamine doses upon admission, and daily complementation of inpatients’ food and enteral feeding solutions with multi-micronutrient tablets might be considered.

Perceptions and Factors Influencing Eating Behaviours and Physical Function in Community-Dwelling Ethnically Diverse Older Adults: A Longitudinal Qualitative Study

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.

Improving Dietary Behavior Among Ethnic Minority Women in Denmark: A Feasibility Study Based on a Participatory and Culturally Adapted Intervention

The Danish Heart Foundation and the non-governmental organization Neighborhood Mothers have co-developed a culturally adapted intervention seeking to promote healthy dietary behaviour among ethnic minority women. This feasibility study explores the potential of the intervention to reach ethnic minority women using health promotion initiatives. Participants attended instructor courses or cooking events, where culturally adapted, healthy recipes were introduced and meals prepared. Feasibility was explored using a mixed-method approach. Surveys were completed by 59 volunteers and 150 participants at five instructor courses and 21 cooking events. Individual interviews and focus group discussions were conducted with volunteers and participants after completion of the intervention. After the intervention, 61% of the 150 participants had high levels of knowledge about dietary recommendations, 96% intended to cook healthy dishes in the future and 84% intended to incorporate measuring equipment into their daily cooking routine. Participants with a high level of knowledge reported intention to change dietary behaviour more often than participants with lower levels of knowledge. Interviews confirmed that the participants cooked healthy dishes after participating, and incorporated knowledge about healthy food practices into their daily cooking. Few participants used measuring equipment. The intervention proved to be feasible as a health promotion initiative targeting a hard-to-reach population.
