Health and nutrition literacy in adults: Links with lifestyle factors and obesity

Nutritional literacy levels of university academic and administrative staff: A cross-sectional study from Turkey

AIM

This study aimed to evaluate the nutritional literacy levels of university academic and administrative staff.

METHODS

Data were collected with a questionnaire including sociodemographic variables, some eating habits, and the Nutritional Literacy Assessment Tool of Adults. A total of 413 individuals, 211 women (51.1%) and 202 men (48.9%), aged 23-64 (mean: 37.41 ± 10.04 years), were included in the study. The data obtained were evaluated with the SPSS 25.0 statistical package program.

RESULTS

It was found that the nutritional literacy level of 18.15% of the participants is at the borderline, 81.85 are sufficient. Women's nutrition literacy scores are significantly higher than men's (p = 0.034). A significant relationship was found between nutritional literacy, socioeconomic status, and some eating habits (p < 0.05). The average daily water consumption of individuals with sufficient nutritional literacy is statistically significantly higher than those with borderline nutritional literacy (p < 0.001). It was determined that individuals with borderline nutritional literacy skipped meals more frequently (p < 0.05).

CONCLUSION

The present study suggests that nutritional literacy may be effective in developing healthy eating behaviors. The study's results can guide the determination of methods that will improve nutritional literacy and increase awareness in the future.

Modifiable predictors of health literacy in working-age adults - a rapid review and meta-analysis

Background

Health 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.

Methods

A 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.

Results

In 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.

Conclusions

Improving 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.
