Emigrants face a high level of food insecurity. There is a wide research gap in the domain of identifying the determinants and problems of dietary acculturation in the context of emigrant students. This article attempts to study the factors affecting the dietary acculturation of African emigrant students in India.

For conducting a first-of-its-kind study for African emigrant students in India, we used field survey method, and the primary data were collected using a pre-structured questionnaire.

This was a field survey conducted in Punjab (a state of India).

One hundred and twenty African emigrant students participated in the survey.

Results of logistic regression indicated that food awareness (P = 0·027) and food suitability (P = 0·043) were the major determinants of dietary acculturation. Lack of familiarity and lack of proximity to food access points are the major problems faced by the African emigrant students. African emigrant students prepared for dietary acculturation largely only after coming to India. There is a significant positive correlation (P = 0·013) between problems faced by the respondents and tendency to prepare for acculturation after coming to India.

Information regarding local food environment plays a significant role in dietary acculturation. There is a pertinent need to educate emigrant students regarding food availability and access by developing suitable educational content.

To explore the dietary habits, nutrient adequacies and dietary change experiences of immigrant and refugee children.

Mixed-methods cross-sectional design. Children completed three 24 h dietary recalls to determine nutrient inadequacies. Parents and service providers were interviewed to capture dietary practices.

Healthy Immigrant Children study, Saskatchewan, Canada.

Three hundred immigrant and refugee children aged 3–13 years and twenty-two parents who lived in Regina or Saskatoon for less than 5 years; twenty-four newcomer services providers.

Immigrant children had higher mean intakes of meat and alternatives, milk and alternatives, and whole grains; and consumed more vitamin B12, folate, Ca, vitamin D, Fe and Zn compared with refugee children. Refugee children were at higher risk of having inadequate intakes of folate (37 %) and Fe (18 %). Both immigrant and refugee children were at high risk of inadequate vitamin D (87 and 93 %, respectively) and Ca intakes (79 and 80 %), and a substantial portion were at risk for inadequate Zn intake (21 and 31 %). Participants mentioned challenges with maintaining a healthy traditional diet in the midst of a busy schedule, while responding to their children’s demands for foods high in fat and sugar.

Newcomer children are at risk for inadequate intakes of vitamin D, Ca and Zn, while refugee children are at additional risk for inadequate folate and Fe intakes. Newcomers to Canada may experience subtle or drastic changes in their food environment leading to dietary acculturation that includes increased consumption of foods high in sugar, salt and fat.

To test Koctürk’s model of dietary change among South-Asian Surinamese in the Netherlands. The model categorizes foods into staple, complementary and accessory foods and postulates that dietary change after migration begins with accessory foods while foods associated with ethnic identity (staple foods) change at a slower rate.

Cross-sectional data from the HELIUS study. Dietary intake was assessed with an FFQ. Acculturation was based on social contacts and sense of belonging and was translated into four strategies of acculturation: assimilation, integration, separation and marginalization. Other indicators of acculturation included residence duration, age at migration and migration generation status.

Amsterdam, the Netherlands.

Participants of Dutch (n 1456) and South-Asian Surinamese origin (n 968).

Across all acculturation strategies, South-Asian Surinamese participants reported significantly higher intakes of rice (staple food) and chicken (complementary food) and significantly lower intakes of red meat and vegetables (complementary foods) and cookies and sweets (accessory food) than Dutch participants. Men, second-generation and assimilated South-Asian Surinamese were inclined towards Dutch foods such as potato, pasta and red meat. Accessory foods like fruits showed variation across acculturation strategies.

Consistent with the Koctürk model, the intake of staple foods was stable among South-Asian Surinamese irrespective of acculturation strategy while the intake of accessory foods like fruit varied. Contrary to expectations, South-Asian Surinamese showed consistently high intakes of complementary foods like chicken and fish irrespective of acculturation strategy. Public health practitioners should take into consideration the complex and dynamic nature of dietary acculturation.

Acculturation to the UK diet may contribute to the increased burden of non-communicable diseases in Black British communities. The present study aimed to assess nutritional composition and the contribution that traditional foods make to dietary intake in a group of UK-residing Caribbean and West African adults and to explore differences according to ethnicity and duration of residence.

Observational study. Dietary intake was assessed using multiple, standardised triple-pass 24 h recalls and analysed using a nutritional composition database. Associations between sociodemographic variables and duration of residence with dietary intake were assessed using ANCOVA.

London, UK, October 2011–December 2012.

UK adults of Caribbean (n 50) or West African (n 83) ancestry, aged 18–75 years.

The Caribbean participants were older and more likely to be born in the UK. After adjusting for age, sex and ethnicity, those who had been resident in the UK for the longest duration had significantly higher intakes of energy (P<0·001), fat (P=0·002) and Na (P=0·03). The West African participants sourced significantly more energy (P=0·04), fat (P=0·02), saturated fat (P=0·02) and Na (P=0·001) from traditional cultural foods compared with the Caribbean diet, which was more reliant on ‘Westernised’ foods such as sugar-sweetened beverages.

These results are novel in demonstrating dietary acculturation in UK adults of Caribbean and West African ancestry. We have provided detailed data regarding the role of traditional foods, presenting dietary information that may guide in individualising care for patients from these communities and improve the cultural sensitivity of public health strategies.

The Hmong are a growing population of South-East Asian immigrants with increasing rates of obesity and diabetes, yet little is known about their dietary consumption patterns. The present study aimed to investigate the dietary intake of Hmong children and whether acculturation and/or time lived in the USA influences dietary intake, BMI and nutritional status.

Two 24 h dietary recalls were collected on non-consecutive days using the multiple-pass interviewing method and were averaged. Heights and weights were measured, from which BMI was calculated. An acculturation score was computed.

Schools, churches, Hmong organizations, and community centres.

Three hundred and thirty-five Hmong children aged 9–18 years from Twin Cities, Minnesota, USA.

Approximately half of our participants were either overweight or obese. US-born children were significantly heavier, taller, had a higher BMI, and in general consumed more energy, saturated fat and Na than those who were born in Thailand/Laos and were living in the USA for <5 years. Children who were more acculturated to US norms including language use, social connections and dietary habits had higher BMI-for-age and consumed significantly more saturated fat, trans fatty acids, Na and Ca compared with their less acculturated counterparts.

Diets of most Hmong children appear below the recommendations for fibre, vitamins A, D and E, Ca, P, Mg and K, and are higher in fats, sugars and Na. Living in an obesogenic US environment is a probable reason for poor dietary quality of Hmong and may be a contributing factor to the rising rates of obesity and diabetes in this population.

To determine whether a short set of questions about foods in the household can provide information about the fat-related dietary behaviour of individual household members in less-acculturated Chinese populations.

Cross-sectional survey.

The study population included 244 adult females of Chinese ethnicity in Seattle, WA, and Vancouver, BC, Canada.

Bilingual interviewers collected information on the presence of 14 high-fat foods and seven reduced-fat foods in the household. Respondents were also asked about the consumption of foods and behaviour reflective of adoption of Western dietary practices, fat-related dietary behaviour, changes in consumption of high-fat foods since immigration, and sociodemographic characteristics.

Although this was a less-acculturated sample, many households had Western foods such as butter (58%), lunchmeats (36%), snack chips (43%), and 1% or skim milk (48%). Households with respondents who were younger, married, employed outside the home, and lived with young children had significantly more high-fat foods, while high education and longer percentage of life in North America were significantly associated with having more reduced-fat foods (P ≤ = 0.05). Participants living in households with more high-fat foods had higher-fat dietary behaviour than those with fewer high-fat foods (fat-related dietary behaviour score, 1.54 versus 1.28; P < 0.001). Women in households with more reduced-fat foods had a significantly decreased consumption of high-fat foods since immigration compared with those in households with fewer reduced-fat foods (P < 0.001). Western dietary acculturation was higher among women in households both with more high-fat foods and more reduced-fat food counterparts (P ≤ 0.05).

Our inventory of household foods was strongly associated with current dietary behaviour, changes in food consumption, and westernization of dietary patterns. This simple, practical measure may be a useful alternative dietary assessment tool in less-acculturated Chinese populations.
