Vitamin D status and dietary intake in young university students in the UK
Purpose
Vitamin D deficiency is prevalent worldwide. This paper aims to investigate the vitamin D status and dietary intake in young university students.
Design/methodology/approach
Forty-one healthy students aged 18–29 years from Coventry University UK were recruited during January-February 2019, including white Caucasians (n = 18), African-Caribbeans (n = 14) and Asians (n = 9). Plasma 25(OH)D concentrations were measured and dietary vitamin D intake was determined. Chi-square and simple linear regression were used to analyse the data.
Findings
The plasma 25(OH)D concentrations were (36.0 ± 22.2) nmol/L in all subjects, (46.5 ± 25.3) nmol/L in white Caucasians, (22.6 ± 7.4) nmol/L in African-Caribbeans and (37.4 ± 21.7 nmol/L) in Asians. The majority (85.7%) of African-Caribbeans were vitamin D deficient compared with 22.2% of white Caucasians and 33.3% of Asians (p = 0.001). Overweight/obese subjects showed a significant higher proportion of vitamin D deficiency (65%) than normal weight subjects (28.6%) (p = 0.04). The average dietary vitamin D intake in all subjects was (4.6 ± 3.9) µg/day. Only 12.1% of the subjects met the recommended dietary vitamin D intake of 10 µg/day. Dietary vitamin D intake (p = 0.04) and ethnicity (p = 0.01) were significant predictors of 25(OH)D levels and accounted for 13% and 18.5% of 25(OH)D variance, respectively.
Research limitations/implications
This small-scale study showed an alarmingly high prevalence of vitamin D deficiency among subjects from African-Caribbean origin during wintertime. Education programs and campaigns are urgently needed to fight the vitamin D deficiency in this population.
Originality/value
The targeted population were in a critical period of transition from adolescence toward adulthood involving in changes in behaviours and nutrition.
期刊介绍:
Nutrition & Food Science* (NFS) is an international, double blind peer-reviewed journal offering accessible and comprehensive coverage of food, beverage and nutrition research. The journal draws out the practical and social applications of research, demonstrates best practice through applied research and case studies and showcases innovative or controversial practices and points of view. The journal is an invaluable resource to inform individuals, organisations and the public on modern thinking, research and attitudes to food science and nutrition. NFS welcomes empirical and applied research, viewpoint papers, conceptual and technical papers, case studies, meta-analysis studies, literature reviews and general reviews which take a scientific approach to the following topics: -Attitudes to food and nutrition -Healthy eating/ nutritional public health initiatives, policies and legislation -Clinical and community nutrition and health (including public health and multiple or complex co-morbidities) -Nutrition in different cultural and ethnic groups -Nutrition during pregnancy, lactation, childhood, and young adult years -Nutrition for adults and older people -Nutrition in the workplace -Nutrition in lower and middle income countries (incl. comparisons with higher income countries) -Food science and technology, including food processing and microbiological quality -Genetically engineered foods -Food safety / quality, including chemical, physical and microbiological analysis of how these aspects effect health or nutritional quality of foodstuffs
