Diet- and body size-related attitudes and behaviors associated with vitamin supplement use in a representative sample of fourth-grade students in Texas

Different Socio-Demographic and Lifestyle Factors Can Determine the Dietary Supplement Use in Children and Adolescents in Central-Eastern Poland

Vitamin/mineral supplement (VMS) use has become increasingly popular in children and adolescents; however, different predictors may be associated with their usage. Therefore, the aim of this study was to compare determinants of VMS use in 1578 children and adolescents. Data was collected among parents of children (≤12 years old) and among adolescents (>12 years old) who attended public schools by a self-administered questionnaire. Multivariate-adjusted logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for determining the predictors of VMS use. In children, the following determinants of VMS use were indicated: socioeconomic status (average vs. very good/good; OR: 1.69, 95% CI: 1.16–2.48), physical activity (1–5 vs. <1 h/week; OR: 1.44, 95% CI: 1.02–2.04), BMI (≥25 vs. 18.5–24.9 kg/m²; OR: 0.67, 95% CI: 0.46–0.98), and presence of chronic diseases (yes vs. no; OR: 2.32, 95% CI: 1.46–3.69). In adolescents, gender (male vs. female; OR: 0.56, 95% CI: 0.37–0.87), residential area (rural vs. urban; OR: 0.63, 95% CI: 0.40–0.99), BMI (<18.5 vs. 18.5–24.9 kg/m²; OR: 0.35, 95% CI: 0.17–0.73), and health status (average/poor vs. at least good; OR: 1.96, 95% CI: 1.13–3.39) were factors of VMS use. In both groups, the mother’s higher educational level, fortified food consumption and diet modification towards better food choices were predictors of VMS use. In conclusion, most of the predictors of VMS use were different in children and adolescents.

The association between sport participation and dietary behaviors among fourth graders in the school physical activity and nutrition survey, 2009-2010

PURPOSE

To determine the association between youth sport team participation and dietary behaviors among elementary school-aged children.

DESIGN

Cross-sectional survey.

SETTING

Public schools in Texas during 2009-2010.

SUBJECTS

A total of 5035 ethnically diverse fourth graders.

MEASURES

Participation in organized sports teams, consumption of select food items (fruits, vegetables, beverages, sweets/snacks).

ANALYSIS

Multiple logistic regression was used to assess the association between each food item (eaten at least once on the previous day) and number of sports teams as the independent class variable (0, 1 ,2, ≥3), adjusting for body mass index physical activity, socioeconomic status, and ethnicity.

RESULTS

Significant dose-response associations were observed between number of sports teams and consumption of fruits and vegetables. For boys, the likelihood of eating fruit and fruit-flavored drinks was significantly higher and the odds of drinking soda were lower with the number of teams. For girls, the likelihood of consuming green vegetables increased as sports teams participation increased, and participation was positively associated with diet soda consumption. A positive association was observed between the number of sports teams and scores on the Healthy Food Index for boys and girls.

CONCLUSION

The findings that sports participation is associated with consumption of fruits and vegetables and lower consumption of soda suggest that efforts should be focused on supporting youth team sports to promote healthier food choices. Since sports are available to all ages, sports may be an important venue for promoting healthier dietary behaviors.

Associations among dietary supplement use and dietary and activity behaviors by sex and race/ethnicity in a representative multiethnic sample of 11th-grade students in Texas

BACKGROUND AND OBJECTIVE

The purpose of this study was to examine associations among dietary supplement use and dietary/activity patterns in a representative sample of adolescents by sex and race/ethnicity, a research area where extant data is limited.

DESIGN/PARTICIPANTS

Cross-sectional, multistage, probability-based sample of 11th graders in Texas during 2004-2005 (n=6,422; 48.8% white/other, 37% Hispanic, and 14.2% African American; 50.6% boys; mean age 16.7 years).

SETTING

Classrooms. MAIN VARIABLES ASSESSED: Dietary supplement use, dietary/activity patterns, and anthropometrics.

STATISTICAL ANALYSES PERFORMED

Multiple logistic regression models (odds ratios [ORs] and 95% confidence intervals [CIs]).

RESULTS

Dietary supplement users reported healthy dietary and physical activity behaviors overall, yet sex- and race/ethnicity-specific differences were seen in associations among specific diet/activity behaviors and supplement use. In whites/others and Hispanics, but not African Americans, supplement use was associated with higher diet quality scores (OR 2.93, 95% CI 1.74 to 4.95 for whites/others; OR 3.93, 95% CI 2.26 to 6.83 for Hispanics), and regular consumption of breakfast (OR 2.27, 95% CI 1.40 to 3.66 for whites/others; OR 1.96, 95% CI 1.11 to 3.46 for Hispanics) and low-fat foods (OR 3.02, 95% CI 1.53 to 5.98 for whites/others; OR 3.59, 95% CI 1.11 to 11.6 for Hispanics). Supplement use was not associated with body mass index or with sedentary behaviors overall, but was associated with less television viewing only in whites/others (OR 0.53, 95% CI 0.33 to 0.84). For physical activity, boys and whites/others showed positive associations between supplement use and all indicators examined, but girls, Hispanics and African Americans showed mixed patterns of associations. Supplement use was associated with higher weight preference only in boys (OR 2.47, 95% CI 1.24 to 4.90), and vegetarian diets only in girls (OR 2.96, 95% CI 1.35 to 6.47).

CONCLUSIONS

Dietary and activity patterns associated with dietary supplement use may vary by sex- and racial/ethnic subpopulation, especially amongst African American youth. These findings together with further research on psychosocial and attitudinal characteristics associated with adolescent supplement use can enhance the development of targeted and tailored health communications about supplement use in adolescent subpopulations.
