Aim: The research was conducted to measure the effect of health literacy-grounded web-based education program on health literacy, nutrition and exercise behaviours in adolescents.
Background: The increasing prevalence of obesity in adolescents is explained by a sedentary lifestyle and unhealthy diet. Health literacy is essential for adolescents to maintain their healthy behaviours.
Methods: The research was conducted as a parallel group randomized controlled trial. The study was completed by 114 adolescents (experimental = 42, control = 72). The Personal Information Form, the Health Literacy Scale for School-Age Children and the Nutrition and Exercise Subscales were used to collect data. A web-based education program was implemented. Two-way mixed design ANOVA with Bonferroni test was used to examine the group, time and group * time interaction of the measurements.
Results: There was no statistically significant difference between the experimental and control groups regarding health literacy level, nutrition and exercise behaviours pre-test mean scores (p > 0.05). In the post-test, the mean scores of health literacy and nutrition behaviours in the experimental group were higher than the control group (p < 0.001). However, there was no significant difference in exercise behaviours (p > 0.05). The power and effect size in mean scores changes for health literacy (99.8%, η = 0.039) and nutrition (99.8%, η = 0.039) were moderate.
Conclusion: The study concluded that health literacy-grounded web-based education program increased the health literacy levels of adolescents and improved their nutritional behaviours; however, there was no sufficient change in exercise behaviours.

By addressing communication gaps, the integration of AI tools in healthcare has a greater ability to improve decision-making and to empower patients with more control over their health. Current systems for navigating healthcare - such as finding providers or understanding costs - are fragmented and cumbersome, often leaving patients frustrated and uninformed. An AI Healthcare Assistant App, leveraging advances in health IT interoperability, price transparency, and user-centred design, could simplify these processes.

Background: Public health professionals (PHPs) have increasing information needs to inform evidence-based public health decisions and practice, which requires good information literacy. A comprehensive and reliable assessment tool is necessary to assess PHPs' literacy and guide future promotion programs. However, there is a lack of measurement tools specifically for the information literacy of PHPs.

Background: eHealth literacy (eHL) is positively associated with health-related behaviors and outcomes. Previous eHL studies primarily collected data from online users and seldom focused on the general population in low- and middle-income countries (LMIC). Additionally, knowledge about factors that affect eHL is limited.

Background: Women's reproductive years are a time of increased vulnerability to mental health problems. However, only a small proportion of women seek help, and seems that poor mental health literacy is a major obstacle in this regard. This study aimed to elucidate the concept and provide a better understanding of the main dimensions of mental health literacy in women of reproductive age.

Objectives: Develop a primary health care-based nurse-led culturally tailored hypertension self-care intervention for rural residents.
Design: The culturally tailored hypertension self-care intervention was developed using a six-step intervention mapping approach that involved: needs assessment using literature review and interviews; setting program goals using integrated thematic synthesis method; selecting intervention modules through the process dimension of the self-care theory of chronic illness; producing program components and materials by developing intervention modules using the motivational interviewing and behavior change techniques; planning program adoption by encouraging sustainable behavior; and evaluation using the education content validity index in health and the intervention acceptability, appropriateness, and feasibility scale.
Measurements: Education content validity index in health and the intervention acceptability, appropriateness, and feasibility scale.
