Vitamin or supplement use among adults, behavioral risk factor surveillance system, 13 states, 2001
Public health reports (Washington, D.C. : 1974)
The authors examined vitamin/supplement (V/S) use and its relationship to sociodemographics, health behaviors, and health conditions among adults in 13 states. This investigation used 2001 data from a cross-sectional study of non-institutionalized adults aged > or = 18 years, the Behavioral Risk Factor Surveillance System. Of 45,415 respondents with complete data (18,723 males and 26,692 females), 56.5% (n=5,652) reported current V/S use. After adjusting for age, sex, race/ethnicity, and education, the authors found a statistically significant association between V/S use and positive health risk behavior (adjusted odds ratio [OR]=1.46; p<0.001). Also, WS use was found to increase with age (p<0.001). No association was found between V/S use and the absence of specific chronic disease conditions (adjusted OR=0.93; p=0.052). People who used V/S in the states surveyed were more likely to demonstrate positive health risk behaviors than those who did not report V/S use. Thus it a...

To describe factors associated with vitamin supplement use in a large cohort of adult women. California teachers and administrators (n = 133,479) completed a questionnaire on lifestyle factors and medical history. Specific supplement users regularly used at least one specific vitamin supplement in the past year; multivitamin users regularly used a multivitamin; and multivitamin and specific supplement users took a multivitamin and one or more specific supplements. Associations between supplement use and other variables were quantified using means, cross-tabulations, and age-adjusted prevalence odds ratios. Multivitamin and specific supplement users tended to be older and Caucasian. Compared to non-users, they were also leaner (odds ratio [OR] for BMI > or = 30 kg/m2 = 0.6 for specific supplement users with or without multivitamins, and OR = 0.7 for multivitamin only users), and were less likely to be current smokers (OR for current smoking = 0.8 for multivitamin plus specific sup...

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. f...
The Prevalence and Awareness Concerning Dietary Supplement Use among Saudi Adolescents
International Journal of Environmental Research and Public Health, 2020
Current dietary supplement (DS) use among Saudi school students is not well described. In this study, we aim to investigate the prevalence and predictors of DS use among adolescents. This cross-sectional study collected data via self-administered questionnaire from 1221 students (12 to 18 years). The overall prevalence of DS use was 26.2%, significantly higher in females than males (33% vs. 17.9%, p < 0.001). High proportion of female DS users demonstrated normal BMI than males (84% vs. 56.5%, p < 0.001). High percentage of male DS users were engaged in vigorous and/or high physical activity (PA) levels than female DS users (58.2% vs. 43%, p = 0.022; and 57.1% vs. 20.7%, p < 0.001, respectively). The main reasons for DS use among females were vitamin deficiency (63.3%), hair condition (37.6%) and nail health (23.5%) while in males, the main reasons were vitamin deficiency (58.4%) and body building (34.4%). The predictors of DS use in Saudi adolescents included being female,...
