Relationship between Diet Quality and Socioeconomic and Health-Related Factors in Adolescents by Gender

Adolescence is a key period for consolidating heathy lifestyles and proper eating habits that can last into adulthood. To analyze the diet quality of Spanish adolescents and its association with socioeconomic factors and health behaviors by gender, a cross-sectional study was conducted using data from the DESKcohort project, consisting of a biannual panel survey on health, health behaviors, and associated determinants, collected in secondary education centers. The study population consisted of 7319 students aged 12 to 18 years. Data were collected from October 2019 to March 2020. The dependent variable was diet quality score according to the Spanish adaptation of the Healthy Eating Index (S-HEI). The independent variables included were socioeconomic factors and health behaviors. We conducted linear regression separately by gender. Diet quality score was significantly higher for girls than for boys (68 and 65, respectively, p < 0.001). For both genders, poorer diet quality was associated with a low level of physical activity [-0.9 (95% CI = -1.6:-0.2) in boys, -1.2 (95% CI = -1.9:-0.4) in girls], alcohol use [-2.5 (95% CI = -3.7:-1.3) in boys, -1.0 (95% CI = -1.9:0.0) in girls], poor self-perceived health [-1.1 (95% CI = -2.4:0.2) in boys, -3.5 (95% CI = -4.6:-2.4) in girls], and having attended Intermediate Level Training Cycles [-2.9 (95% CI = -4.3:-1.5) in boys, -1.9 (95% CI = -3.5:-0.3) in girls]. In girls, poorer diet quality also was associated with low mood [-1.1 (95% CI = -1.9:-0.3)]. The variance was 9% in boys and 12% in girls. Our results highlight the need to consider socioeconomic and health-related factors, as well as gender, when conducting interventions to promote healthy eating among adolescents.

Younger age, higher father education level, and healthy lifestyle behaviors are associated with higher adherence to the Mediterranean diet in school-aged children

OBJECTIVES

This study aimed to assess adherence to the Mediterranean Diet (MDiet) in school-aged children in Turkey and explore the associated factors with high adherence to the MDiet.

METHOD

This cross-sectional was conducted with 2693 school-aged children. Sociodemographic, dietary, and lifestyle data were collected using a questionnaire. Mediterranean Diet Quality Index (KIDMED) was used to evaluate adherence to the MDiet. Body weight, height, neck, waist, and hip circumference were measured. Dietary intake was assessed with a 24-h food consumption record.

RESULTS

Of the 2693 children, 29.5% had high, 53.9% had moderate, and 16.6% had low adherence to the MDiet. Primary school children had significantly higher adherence to the diet than secondary school children. Adherence to the MDiet was higher in children whose fathers were university graduates. There were no significant differences in sex, body mass index (BMI), or anthropometric measurements according to MDiet adherence. The high adherence group had a significantly higher intake of protein, fiber, vitamins C, B1, B6, B2, folate, polyunsaturated fatty acids, zinc, potassium, and calcium, but lower carbohydrate intake compared with the low/moderate adherence group. Higher adherence to the MDiet was associated with adequate sleep duration (≥9 to <12 h) (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.24-2.78), whereas poor/moderate adherence was associated with age (OR, 0.80; 95% CI, 0.73-0.87) and screen time (OR, 0.50; 95% CI, 0.40-0.63). Children who reported engaging in regular physical activity were more likely to have higher MDiet adherence (OR, 1.46; 95% CI, 1.16-1.85).

CONCLUSION

The results of this study showed that >50% of the children presented moderate MDiet adherence. Younger age, adequate sleep duration, engaging in regular physical activity, less screen time, and higher education level of fathers were associated with higher adherence to the diet.

Factors associated with non-frequent breakfast consumption in adolescents (EVA-JF Study)

ABSTRACT Objective To estimate the association of infrequent breakfast consumption with socioeconomic, behavioral, and individual factors in a sample of Brazilian adolescents from public schools. Methods Cross-sectional study with adolescents aged from 14 to 19 from public schools in Juiz de Fora, state of Minas Gerais. The frequency of consumption of breakfast, snacks, soft drinks, industrialized drinks, the usual food consumption, body mass index, body fat percentage, and waist circumference were evaluated. Other socioeconomic, behavioral, and individual data were obtained through questionnaires. Logistic regression analysis and hierarchical selection of variables were used to verify the associated factors. Results The sample consisted of 805 adolescents; 53.4% reported infrequent breakfast consumption. Through hierarchical logistic regression analysis, it was evidenced that the house occupancy status (OR: 0.618; 95%CI: 0.4410.865; p=0.005) was the distal factor associated with infrequent breakfast consumption; the intermediate factors were the consumption of industrialized beverages (OR: 0.658; 95%CI: 0.486-0.890; p=0.007) and percentage of energy from processed foods (OR: 0.935; 95%CI: 0.907-0.964; p<0.001); and the proximal factors were the male gender (OR: 0.696; 95%CI: 0.520-0.932; p=0.0015) and being nonwhite (OR: 1.529; 95%CI: 1.131-2.069; p=0.006). Conclusion Male adolescents who lived in owned houses, with occasional consumption of industrialized beverages and a higher percentage of energy derived from processed foods, had lower chances of infrequent breakfast consumption, while non-white adolescents had higher chances.

Changes in food habits amongst Norwegian adolescents in 2016 and 2019 according to gender and socioeconomic status

Background

Monitoring dietary habits is important in order to identify risk groups and as a basis for targeted public health initiatives.

Objective

To study trends in consumption of selected foods and beverages from 2016 to 2019 amongst Norwegian adolescents according to gender and parental education.

Design

Repeated cross-sectional study amongst 25,996 adolescents, aged 14–17 years old. Consumption of selected food and beverages was measured by an online food frequency questionnaire and general linear models were applied to estimate changes in dietary habits.

Results

Between 2016 and 2019, we observed a reduced frequency of consumption of vegetables (from 4.7 to 4.4 times/week), fruit and berries (from 4.4 to 4.2 times/week), whole-grain bread (from 5.1 to 4.2 times/week), and fish (from 2.3 to 1.6 times/week). During this time period, we also observed a reduced frequency of consumption of salty snacks (from 2.1 to 1.9 times/week), sweets (from 2.3 to 2.0 times/week), sugar-sweetened beverages (from 2.8 to 2.6 times/week), and artificially sweetened beverages (from 2.2 to 1.5 times/week). In girls, there was a decrease in the reported frequency of consumption of fruit and berries (−4%, vs. no change in boys). The decrease in consumption frequency of whole-grain bread was larger in girls than in boys (−19% vs. −14%). Further, a 17% decrease in consumption of sweets was observed amongst adolescents with no or only one parent having college/university education compared to a 13% decrease in adolescents whose both parents had college/university education.

Conclusion

Our results showed a decrease in frequency of consumption of selected healthy and unhealthy food and beverages amongst adolescents between 2016 and 2019. The gender gap in consumption of fruit and berries and whole-grain bread seemed to decrease during this time period, and the socio-economic gap in consumption of sweets seemed to disappear.

Three-Year Intervention Effects on Food and Beverage Intake-Results from the Quasi-Experimental Copenhagen School Child Intervention Study (CoSCIS)

The diet of Danish children is often not in accordance with dietary guidelines. We aimed to evaluate changes in the intake of selected foods and beverages during a multi-component school-based physical activity intervention, and to investigate if changes were modified by socioeconomic status (SES). The study included 307 children (intervention group: 184; comparison group: 123) with information on dietary intake pre- and post-intervention as well as on SES. Linear regression models were conducted to assess the effect of the intervention on changes in dietary factors. Children from the intervention group increased their intake of whole-grain bread during the intervention (group means: 6.1 g/d (95% CI: 2.2 to 10.0) vs. 0.3 g/d (95% CI: −3.1 to 3.7) in the comparison group, p = 0.04). A significant interaction between SES and group allocation was observed to change in fruit intake (p = 0.01). Among children from low SES families, only those from the comparison group decreased their fruit intake (group means: −40.0 g/d (95% CI: −56.0 to −23.9) vs. 9.3 g/d (95% CI: −16.1 to 94) in the intervention group, p = 0.006). The present study found no convincing effect of introducing a multi-component intervention on dietary intake except a small beneficial effect on whole-grain bread consumption. However, beneficial intervention effects in fruit intake were found particularly among children from low SES families.

Predictors of breakfast skipping among 14 to 16 years old adolescents in Jordan: The influential role of mothers

AIM

To assess the prevalence and identify the predictors of breakfast skipping among 14- to 16-year-old adolescents in Jordan, focusing on mother-related variables.

BACKGROUND

Breakfast is an essential meal across one's entire lifespan and especially important during the adolescent years. The practice of skipping breakfast has become so prevalent among adolescents that it is now a well-documented nutritional problem.

DESIGN

A descriptive cross-sectional correlational design.

METHODS

A proportional cluster stratified sampling protocol was used to select 1896 adolescents and their mothers (1013) during the period of March to June 2016. A self-reported questionnaire was used to collect data on breakfast-skipping rates, the perceived reasons for this behavior, the perceived importance of consuming breakfast, and maternal encouragement of breakfast consumption.

RESULTS

The prevalence of breakfast skipping was 34.3% among adolescents and 21.5% among their mothers. A significant association was found between breakfast skipping among adolescents and their mothers (χ² [1, n = 998] = 37.90, P = .001). Maternal encouragement of breakfast consumption, gender, and adolescent perception of the importance of this meal were found to be significant predictors of adolescent breakfast skipping.

CONCLUSION

The findings highlight the importance of involving mothers in developing nutritional health plans aimed at promoting regular breakfast consumption among adolescents.

The Role of Body Image in Internalizing Mental Health Problems in Spanish Adolescents: An Analysis According to Sex, Age, and Socioeconomic Status

During adolescence there is a relatively high prevalence of weight problems and eating disorders. Furthermore, body image plays an important role in weight control and eating behaviors as well as in mental health. This study analyses the influence of body mass index, perception of being overweight, and body image satisfaction (BIS) on internalizing symptoms related to mental health in adolescents. In addition, sex, age, socioeconomic status (SES), dieting, and physical activity are taken into consideration. This research is based on the international study Health Behaviour in School-aged Children (HBSC). The sample consists of 4531 Spanish adolescents from 13 to 18 years old. Participants were selected through random multi-stage sampling stratified by conglomerates. Two instruments were employed: the HBSC questionnaire and the Youth Self-Report (Achenbach System of Empirically Based Assessment, ASEBA). Results demonstrated that BIS –the emotional component related to body image– was the main predictor of adolescent internalizing symptoms. In addition, results show double-inequalities according to the interaction effects of sex, age, and SES. Likewise, interesting results are shown regarding how dieting behaviors to lose or gain weight/volume and physical activity relate to body image perception and satisfaction, as well as with internalizing symptoms. This study highlights important body image aspects relevant to intervention and prevention of internalized mental health problems in adolescence.
