Socioeconomic disparities in diet vary according to migration status among adolescents in Belgium

Little information concerning social disparities in adolescent dietary habits is currently available, especially regarding migration status. The aim of the present study was to estimate socioeconomic disparities in dietary habits of school adolescents from different migration backgrounds. In the 2014 cross-sectional Health Behavior in School-Aged Children survey in Belgium, food consumption was estimated using a self-administrated short food frequency questionnaire. In total, 19,172 school adolescents aged 10-19 years were included in analyses. Multilevel multiple binary and multinomial logistic regressions were performed, stratified by migration status (natives, 2nd- and 1st-generation immigrants). Overall, immigrants more frequently consumed both healthy and unhealthy foods. Indeed, 32.4% of 1st-generation immigrants, 26.5% of 2nd-generation immigrants, and 16.7% of natives consumed fish two days a week. Compared to those having a high family affluence scale (FAS), adolescents with a low FAS were more likely to consume chips and fries once a day (vs. <once a day: Natives aRRR = 1.39 (95%CI: 1.12-1.73); NS in immigrants). Immigrants at schools in Flanders were less likely than those in Brussels to consume sugar-sweetened beverages 2-6 days a week (vs. once a week: Natives aRRR = 1.86 (95%CI: 1.32-2.62); 2nd-generation immigrants aRRR = 1.52 (1.11-2.09); NS in 1st-generation immigrants). The migration gradient observed here underlines a process of acculturation. Narrower socioeconomic disparities in immigrant dietary habits compared with natives suggest that such habits are primarily defined by culture of origin. Nutrition interventions should thus include cultural components of dietary habits

Socioeconomic and sociocultural disparities in the dietary habits of adolescents in Belgium: Analysis of the "Health Behaviour in School-aged Children" Surveys

Diet contributes to a large proportion of preventable deaths and diseases. Adolescence is a period during which diet may particularly evolve, and therefore represents an opportunity to develop long-lasting healthy dietary behaviours. However, dietary habits are particularly subject to social variations, which may lead to social inequalities in health. Tackling them requires public health actions based on a comprehensive approach of social determinants at this life stage. This doctoral thesis aimed to examine socioeconomic and sociocultural disparities in dietary habits among adolescents, using the repeated cross-sectional Health Behaviour in School-aged Children (HBSC) surveys conducted in French- and Dutch-speaking Belgian schools. The three specific objectives of this aim were: (i) to study the socioeconomic disparities in dietary habits of adolescents from different migration status; (ii) to determine trends in dietary disparities between 1990 and 2014; (iii) to estimate disparities in dietary habits according to the socioeconomic and migration status at both individual and contextual levels. Firstly, different socioeconomic disparity patterns according to the migration status were observed, with narrower disparities in 1st-generation immigrants than among natives, highlighting the major role of cultural influences in immigrant populations. Secondly, the long-term trend analyses emphasised increasing disparities for healthy foods and decreasing disparities for unhealthy foods. In addition, when the consumption of a food group increased overall, disparities decreased, and vice-versa. Finally, the multilevel analyses showed that individual and school disparities were independently associated with food consumption frequencies. Furthermore, this observational assessment revealed the weak relationships between nutrition policy in schools and dietary habits. Note that in the Brussels-Capital Region, native adolescents were at higher risk of unhealthy dietary behaviours than immigrants, but the risk of unhealthy behaviours tended to be higher when, in the school, the socioeconomic index decreased, and the proportion of immigrants increased. Overall, our analyses underlined the need to include, in addition to the socioeconomic factors, cultural components in public health actions aimed at addressing social inequalities in adolescent diet, in a multicultural context such as Belgium. Support to schools, with a greater emphasis on those disadvantaged in order to prevent increased inequalities, is needed to develop a consistent and effective nutrition policy. Finally, further studies are needed to better understand the mechanisms behind dietary disparities among adolescents, particularly those related to their migration status and broader socioeconomic environment.Doctorat en Santé Publiqueinfo:eu-repo/semantics/nonPublishe

Food Consumption in Adolescents and Young Adults: Age-Specific Socio-Economic and Cultural Disparities (Belgian Food Consumption Survey 2014)

A key issue in nutritional public health policies is to take into account social disparities behind health inequalities. The transition from adolescence toward adulthood is a critical period regarding changes in health behaviors. This study aimed to determine how consumption of four emblematic food groups (two to favor and two to limit) differed according to socio-economic and cultural characteristics of adolescents and young adults living in Belgium. Two non-consecutive 24-h dietary recalls were carried out in a nationally representative sample of 10–39 year old subjects (n = 1505) included in the Belgian food consumption survey 2014. Weighted daily mean consumption of “fruits and vegetables”, “whole grain bread and cereals”, “refined starchy food”, and “sugary sweetened beverages” (SSB) was calculated and explored in multivariable linear regressions stratified into four age groups. After adjustment, 10–13 year old adolescents living in less educated households daily consumed lower amounts of “fruits and vegetables” (adjusted mean: 165.6 g/day (95% CI: 125.3–206.0)) and “whole grain bread and cereals” (40.4 g/day (22.9–58.0)), and higher amounts of SSB (309.7 g/day (131.3–488.1) than adolescents of same ages living in more educated households (220.2 g/day (179.8–260.7); 59.0 g/day (40.3–77.8); and 157.8 g/day (1.7–314.0), respectively). The same trends were observed in older groups, along with strong consumption disparities according to region of residency, country of birth, and occupation, with specificities according to age. Our findings suggest the need to better explore such disparities by stage of transition to adulthood, and to adapt nutritional health programs.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Ten-year changes in diet quality among adolescents and young adults (Food Consumption Survey 2004 and 2014, Belgium)

Purpose: To estimate the 10-year change in the overall nutritional quality of adolescent and young adult’s diet, as measured by the modified Nutrient Profiling System of the British Food Standards Agency individual Dietary Index (FSAm-NPS-DI) which funds the Nutri-Score development, and in different components of this score, overall and according to the individual characteristics. Methods: Two 24-h dietary recalls were carried out in 15- to 39-year-old respondents included in the Belgian Food Consumption Surveys in 2004 (n = 1186) and 2014 (n = 952). The weighted mean individual FSAm-NPS-DI was computed from all foods and beverages consumed, converted into a scale from 0 to 100 (from the poorest to the most favorable diet), and compared between survey years. Subject characteristics associated with the score, along with the mean daily intake of food groups, energy, and nutrients were explored in multiple linear regressions stratified by survey year and age group. Results: The weighted mean daily FSAm-NPS-DI significantly increased between 2004 and 2014 [2004: 55.3 (SEM: 0.2) vs. 2014: 57.4 (0.5), P < 0.001 in 15- to 18-year olds; 55.0 (0.6) vs. 58.1 (0.4), P < 0.001 in 19- to 25-year olds; 57.1 (0.4) vs. 58.5 (0.3), P < 0.01 in 26- to 39-year olds]. SFA intake decreased in all age groups, and sugar-sweetened beverage, sugar, sodium, and fiber intakes decreased among 15‒18-year olds. The nutritional quality changed unevenly according to sociocultural characteristics, levels of education and regions being the main sources of disparities. Conclusion: The quality of diet improved overall between 2004 and 2014 among young people in Belgium, an uneven change that need to be confirmed in future surveys, following the implementation of the Nutri-Score.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
