Abstract
This NED Infobite takes a look at some aspects of health and nutrition through the diversity and inclusion lens. It includes studies on nutrition and lifestyle interventions in under-served communities, health disparities during the COVID-19 pandemic in ethnic minority and migrant populations, as well as a look at the socio-demographic risk factors related to Type 2 diabetes.

Assessment of vitamin B12 deficiency and B12 screening trends for patients on metformin: a retrospective cohort case review
BMJ Nutrition, Prevention & Health aims to present the best available evidence of the impact of nutrition and lifestyle factors on the health of individuals and populations. The journal will present robust research on the key determinants of health including the social, economic, and physical environment, as well as lifestyle and behaviour. It will explore dietary factors, exercise, healthcare interventions and technologies, which aim to maintain and improve health and wellbeing and to prevent illness and injury.

Abstract
This study investigates the impact of > 1-year use of metformin on vitamin B12 levels of patients. Populations at a greater risk for B12 deficiency rates included: patients with >5 years of metformin use, and those aged > 65 years old. The African-American population was tested at a lower rate (<15% less likelihood of being tested compared with non-African-Americans) and has historically always been; suggesting that further research is required to analyse this ethnic group's response. This research encourages practitioners to consider B12 deficiency screening in these populations, even if asymptomatic.

Plain language summary
Ethnic inequalities in a wide range of chronic diseases are well documented. Poor dietary habits in childhood may contribute to higher rates of chronic diseases such as type 2 diabetes (T2D), hypertension and Coronary Heart Disease (CHD). This study was a longitudinal follow-up of a subsample of the Determinants of Adolescent Social well-being and Health (DASH) study. The researchers aimed to identify dietary patterns and investigate their impact on chronic diseases in young adulthood. The study participants were 107 White British, 102 Black Caribbean, 132 Black African, 98 Indian, 111 Bangladeshi/Pakistani and 115 other/mixed ethnicity. Participants completed a 24-hour dietary intake recall and behaviour questionnaire at age 11-13yrs, and then again at age 21-23yrs. Body mass index (BMI), blood pressure, blood cholesterol and blood sugar were measured. The researchers found that dietary behaviours such as skipping breakfast and a low intake of fruit and vegetables were common. Rates of skipping breakfast and low fruit and vegetable consumption were highest among Black African and Black Caribbean participants. BMI and cholesterol levels in young adults were higher among those who regularly skipped breakfast. The researchers concluded that skipping breakfast is more common in certain ethnic groups and is associated with risk factors for chronic disease in young adults. They suggest that interventions to improve dietary habits could be targeted at specific population groups.
Abstract
Unfavourable dietary habits, such as skipping breakfast, are common among ethnic minority children and may contribute to inequalities in cardiometabolic disease. We conducted a longitudinal follow-up of a subsample of the UK multi-ethnic Determinants of Adolescent Social well-being and Health cohort, which represents the main UK ethnic groups and is now aged 21-23 years. We aimed to describe longitudinal patterns of dietary intake and investigate their impact on cardiometabolic risk in young adulthood. Participants completed a dietary behaviour questionnaire and a 24 h dietary intake recall; anthropometry, blood pressure, total cholesterol and HDL-cholesterol and HbA1c were measured. The cohort consisted of 107 White British, 102 Black Caribbean, 132 Black African, 98 Indian, 111 Bangladeshi/Pakistani and 115 other/mixed ethnicity. Unhealthful dietary behaviours such as skipping breakfast and low intake of fruits and vegetables were common (56, 57 and 63 %, respectively). Rates of skipping breakfast and low fruit and vegetable consumption were highest among Black African and Black Caribbean participants. BMI and cholesterol levels at 21-23 years were higher among those who regularly skipped breakfast at 11-13 years (BMI 1·41 (95 % CI 0·57, 2·26), P=0·001; cholesterol 0·15 (95 % CI -0·01, 0·31), P=0·063) and at 21-23 years (BMI 1·05 (95 % CI 0·22, 1·89), P=0·014; cholesterol 0·22 (95 % CI 0·06, 0·37), P=0·007). Childhood breakfast skipping is more common in certain ethnic groups and is associated with cardiometabolic risk factors in young adulthood. Our findings highlight the importance of targeting interventions to improve dietary behaviours such as breakfast consumption at specific population groups.

Plain language summary
Vitamin D is essential for healthy bones, and low vitamin D status is associated with an increased risk of chronic diseases such as cardiovascular disease and type 2 diabetes. Ethnic minority populations with darker skin are considered as a high-risk group for vitamin D deficiency, owing mainly to having less ability to synthesise vitamin D from sunlight due to the skin pigment melanin and/or reduced skin exposure due to clothing required by religious or cultural traditions. The aim of this literature review was to evaluate vitamin D intake and status of ethnic minority populations with darker skin. The authors examined previous observational studies and randomised controlled trials. Ethnic minority populations generally have a lower vitamin D status than white populations. Compared with Caucasians, there is evidence that Asians require approximately three times longer periods of sunlight exposure, and Africans six times the same exposure, to achieve the same blood levels of vitamin D. The main food sources for dietary vitamin D intake were different for ethnic minority populations and white populations. There is limited evidence on the impact of vitamin D supplementation on different ethnic groups. The authors concluded that food fortification could be explored to increase dietary vitamin D intake in ethnic minority populations who generally have lower levels of vitamin D.
Abstract
In recent years, vitamin D deficiency has attracted attention worldwide. Especially many ethnic minority populations are considered at high-risk of vitamin D deficiency, owing to a lesser ability to synthesis vitamin D from sunlight (ultraviolet B), due to the skin pigment melanin and/or reduced skin exposure due to coverage required by religious and cultural restrictions. Therefore, vitamin D intake from dietary sources has become increasingly important for many ethnic minority populations to achieve adequate vitamin D status compared with the majority of the population. The aim of the study was critically evaluate the vitamin D intake and vitamin D status of the ethnic minority populations with darker skin, and also vitamin D absorption from supplements and ultraviolet B. Pubmed, Embaase and Scopus were searched for articles published up to October 2018. The available evidence showed ethnic minority populations generally have a lower vitamin D status than the majority populations. The main contributory food sources for dietary vitamin D intake were different for ethnic minority populations and majority populations, due to vary dietary patterns. Future strategies to increase dietary vitamin D intake by food fortification or biofortification needs to be explored, not only for the majority population but more specifically for ethnic minority populations who are generally of lower vitamin D status.
