Nutritional Behaviors, Health Literacy, and Health Locus of Control of Secondary Schoolers in Southern Poland: A Cross-Sectional Study

Exploring healthy lifestyle with health locus of control and sociodemographic variables in Türkiye

In this study, we aimed to explore the effects of Internal/Chance/Powerful Others Health Locus of Control (IHLC/CHLC/PHLC) on the healthy lifestyle and to assess the sensitivity of the healthy lifestyle to sociodemographic variables. To achieve this goal, we collected data by performing online and hand-delivered surveys (n = 950) with individuals aged 18 or older in Türkiye. The results showed that IHLC and PHLC had positive and significant effects on Healthy Lifestyle Index (HLI). However, the results expressed that CHLC had no negative and significant effect on HLI. Our assessment of a healthy lifestyle in terms of health locus of control (HLC) and sociodemographic variables revealed important findings, which may contribute to the development of public health strategies in several ways; for example, they can be used as a framework to conduct public health interventions that promote a healthy lifestyle.

Can Nutritional Status in Adults Be Influenced by Health Locus of Control?

The external health locus of control (HLC) is based on an assumption that obtained health results depend on the influences of external factors. As for the internal HLC-that is the effect of our own actions and capabilities. Little is known regarding how the HLC can influence body weight or the occurrence of visceral obesity. The study aimed to assess the relationship between the health locus of control and nutritional status in adults. The study included 744 adults (452 women, 292 men; 2.8% underweight, 43.8% normal weight, 29.7% overweight, and 23.7% obese). In addition to anthropometric measurement and socio-demographic data, the health locus of control, using the Multidimensional Health Locus of Control Scale (MHLC) by Wallston K, Wallston B, and DeVellis R, was assessed. The percentage of subjects with an internal HLC did not differ significantly between obese, overweight, and normal-weight groups. However, the percentage of subjects with an external HLC-dependent on the impact of others-was significantly higher in both men and women with obesity than in corresponding overweight and normal-weight groups (p < 0.01). Yet, the percentage of subjects with an external HLC subject to the impact of chance was significantly higher among overweight and obese women than in those of normal weight (p < 0.05) only. Women with overweight or obesity, with external health locus of control, experienced both the impact of others and of chance more often than women with normal weight. However, men with overweight and with obesity more often had external health locus of control influenced only by others.

Promoting Sustainable Lifestyle Habits: “Real Food” and Social Media in Spain

Obesity and state of being overweight are beginning to be treated as global epidemics. In this context, health professionals are increasingly acting as expert opinion leaders that use social media to connect with the public, in order to promote healthy lifestyles and provide specific recommendations for different product categories, including fresh, processed, and ultra-processed meat products. This study investigates how exposure to content created by health professionals, and posted on social media, influences consumers’ attitudes. For this purpose, the collaboration of one relevant nutritionist influencer in Spain has been obtained. The online survey created has provided 4.584 responses, received from followers (from May to June 2019). After applying a partial least squares path modeling approach, the results suggest that trust in the content shared, the perceived credibility of the professional sharing the information and the informative value, determine the strength with which consumers acquire more knowledge about endorsed products, develop a favorable predisposition towards them, prefer them over their options, and modify their behaviour by purchasing them, instead of their usual foods. The link is stronger, in the case of trust and influencer’s credibility, than for informative value. However, the latter has an indirect effect on the attitude phases through the former.

IS THERE AN ASSOCIATION BETWEEN HEALTH LITERACY AND ADHERENCE TO THE MEDITERRANEAN DIET? A CROSS-SECTIONAL STUDY IN GREECE

OBJECTIVE

The aim: To evaluate the relationship between adherence to the Mediterranean diet and health literacy and to find possible differences based on the demographic characteristics of the participants.

PATIENTS AND METHODS

Materials and methods: A cross-sectional study was carried out with a convenience sample from the Greek general population (n=203). The questionnaires were distributed through the Google Forms platform, while some of them were given on hand. The questionnaire used included demographic information, questions about the participants' health status and nutrition habits and the Health Literacy Scale (HLS - EU-Q16) and the MedDietScore. The survey was conducted June - July 2022. The program SPSS v. 26.0 was used for the analysis of data.

RESULTS

Results: The mean score in HLS-EU-Q16 was 12.08 (SD=4.17) (15.8%=inadequate level, 30% =problematic level, 54.2%=sufficient level). The mean score in Med DietScore was 31.54 (SD=4.84) and the majority (72.4%) had medium adherence to the Mediterranean diet. Concerning the HLS-EU-Q16, women and those who had not children, were not patients and used the Internet for finding health information had higher score. In contrast, widows/ers and those with elementary education had lower score. With regard to the Med DietScore, those who were patients and had normal weight had higher score than the rest categories. A negative correlation was found between age-HLS-EU-Q16 (r=-.605, p<.01) and between BMI-Med DietScore (r=-.142, p<.05).

CONCLUSION

Conclusions: Most of the participants had sufficient level of health literacy and medium adherence to the Mediterranean diet. Furthermore, there was not a significant correlation between adherence to the Mediterranean diet and health literacy. Several demographic and medical characteristics impact the health literature level and the adherence to the Mediterranean diet. Future research is suggested to further evaluate the results of this study.
