Causal model of health literacy in dietary supplement use and sufficient health behavior among working-age adults.

ABSTRACT:

Background

Sufficient health behavior (SHB) and health literacy in dietary supplement use (HL-DSU) are the key determinants of health status. However, the link between HL-DSU and SHB is not fully understood. Therefore, the objective of this research was to investigate the model and identify the size of its effect on HL-DSU and SHB among adults of working age.

Methods

The study employed a cross-sectional survey design, with cluster random sampling used for the selection of 696 working-age adults ranging from 20-59 years. Data on their SHB, HL-DSU, awareness of dietary supplement advertising (DSA), and social support were collected from August to October 2021 through questionnaires employing a 5-point rating scale. Content validity was determined using item-objective congruence (IOC) values ranging from 0.6 to 1.0 obtained for each item on the questionnaire. The Cronbach's alpha values ranging from 0.93 to 0.96 indicated reliability, while the independent t-test, descriptive analysis, and structural equation modeling (SEM) were performed.

Results

SHB is defined as the health-beneficial behaviors based on a balanced lifestyle, utilizing conceptual approaches resulting in positive health outcomes relating to fundamental goals in the use of dietary supplements and other contexts emphasizing sufficiency. The causal model was found to fit the empirical data with an acceptable goodness-of-fit value. The findings indicate that social support, awareness of DSA, and HL-DSU directly affect SHB (Beta of 0.33, 0.20, and 0.13, respectively, p < .05) and could predict 34% of SHB overall. HL-DSU is shown to be significantly and directly impacted by social support and awareness of DSA, with influence coefficients of 0.36 and 0.57, respectively. The variance of HL-DSU can be predicted by these two factors as 67%.

Conclusion

The establishment of campaign activities to promote awareness regarding the advantage and disadvantages, as well as media literacy of supplementary food products in health centers and communities, should be the focus of healthcare providers.

Project description:BackgroundHealth literacy comprises the ability to identify, obtain, interpret and act upon health information. Low health literacy is a major risk factor for hospitalizations, use of emergency care and premature mortality among others. Known risk factors for low health literacy such as lower educational attainment, migration history and chronic illnesses overlap with those for long-term unemployment - in itself a risk factor for low health literacy. These factors are difficult to address in interventions to support health literacy. Therefore, the objective of this review is to identify potentially modifiable predictors of HL in populations potentially affected by long-term unemployment.MethodsA rapid review (PROSPERO registration number: 290873) was carried out in Pubmed and SCOPUS including quantitative studies on potentially modifiable predictors of health literacy in working-age populations following PRISMA guidelines for systematic reviews. Where possible, reported effect sizes were transformed into r, and random-effects meta-analyses were conducted where appropriate to pool effect sizes for the association between modifiable predictors and health literacy.ResultsIn total, 4765 titles and abstracts were screened, 114 articles were assessed in full-text screening, and 54 were included in the review. Forty-one effect sizes were considered for 9 different meta-analyses. Higher language proficiency, higher frequency of internet use, using the internet as a source of health information more often, being more physically active, more oral health behaviours, watching more health-related TV and a good health status were significantly associated with higher health literacy. Significant heterogeneity suggests between-study differences.ConclusionsImproving language proficiency and/or providing information in multiple and simplified languages, together with reliable and accessible health information on the internet and in linear media are potentially promising targets to improve health literacy levels in working-age populations.

Project description:BackgroundExperiencing financial insecurity and being underserved is often associated with low health literacy, i.e., the ability to identify, obtain, interpret and act upon health information, which may result in poor health outcomes. Little is known about effective interventions for promoting health literacy among underserved populations. The objective of this systematic review is to summarize the literature on such interventions and identify characteristics that differentiate more effective interventions.MethodsFollowing PRISMA guidelines we searched the databases SCOPUS, Pubmed, Web of Science core collection and CINAHL. We included primary studies with a quantitative study design and control groups testing interventions to increase health literacy or health knowledge in underserved populations between 18 and 65 years. Where possible, we converted effect sizes into Cohen's d and compared mean differences of intervention and control groups. Albatross plots were created to summarize the results according to different health literacy and health knowledge outcomes.ResultsWe screened 3,696 titles and abstracts and 206 full texts. In total, 86 articles were analyzed, of which 55 were summarized in seven albatross plots. The majority of the studies (n = 55) were conducted in the United States and had a randomized controlled study design (n = 44). More effective intervention approaches assessed needs of participants through focus group discussions prior to conducting the intervention, used bilingual educational materials, and included professionals fluent in the first languages of the study population as intervention deliverers. Additionally, the use of educational materials in video and text form, fotonovelas and interactive group education sessions with role playing exercises were observed to be effective.DiscussionAlthough the outcomes addressed in the included studies were heterogeneous, effective intervention approaches were often culturally sensitive and developed tailored educational materials. Interventions aiming to promote health literacy in underserved populations should hence consider applying similar approaches.Systematic review registration: https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=323801, PROSPERO registration ID: CRD42022323801.

Project description:ObjectiveTo prospectively examine the long-term safety of a cardiovascular health dietary supplement by assessing a comprehensive set of safety measures.DesignSingle-arm, open-label study.LocationNational University of Natural Medicine, Portland, OR.SubjectsThirty adults with screening blood pressure readings consistent with prehypertension or stage I hypertension.InterventionOne caplet per day of a dietary supplement for 6 months. The investigated herbal-mineral supplement contains several ingredients, most notably Rauwolfia serpentina.Outcome measuresPrimary measures included b-type natriuretic peptide (NT-proBNP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), estimated glomerular filtration rate (eGFR), electrolytes, and the Patient Health Questionnaire (PHQ-9). Exploratory measures included physical vital signs, cholesterol levels, high-sensitivity cardiac troponin-I, cystatin C, endothelin, interleukin (IL)-6, IL-17a, tumor necrosis factor-α, high-sensitivity C-reactive protein, blood counts, and the Patient Reported Outcome Measure Information System (PROMIS) Sleep Disturbance Short Form 8b.ResultsNT-proBNP, AST, ALT, eGFR, sodium, calcium, magnesium, PHQ-9 score, and the majority of exploratory measures did not change. However, serum potassium increased (p < 0.05), systolic blood pressure decreased (p < 0.0001), and diastolic blood pressure decreased (p < 0.0001). There were no serious adverse events, but 30% of participants withdrew citing potential side effects, most commonly nasal congestion or fatigue; most participants who reported nasal congestion also reported concomitant seasonal allergies. Adherence to the supplement was 90.9%.ConclusionsThe findings of this study suggest that the investigated dietary supplement is safe for long-term use in adults with prehypertension and stage I hypertension. Additional results of this study, particularly the increase in serum potassium and decreases in systolic and diastolic blood pressure, are promising and suggest that future research on this dietary supplement, or its ingredients, should further explore effects on blood pressure and biologic mechanisms of action, which may involve potassium-sparing and diuretic effects.
