Health Literacy And Body Mass Index: A Population-Based Study In A South-Eastern European Country

Background The relationship of health literacy (HL) with objective measures including anthropometric measurements remains an under-researched topic to date.Objective To assess the association between body mass index (BMI) and HL among Albanian adults.Methods A cross-sectional study was conducted in Tirana, Albania, in 2012-2014 including a population-based sample of 1154 individuals aged >= 18 years. HL was assessed by the use of HLS-EU-Q instrument. Anthropometrics included measurement of weight and height based on which BMI was calculated. Information on socio-demographic characteristics was also collected. Logistic regression was employed to assess the independent association of BMI and HL controlling all socio-demographic factors.Results One-fifth of the participants reported an inadequate HL level, whereas almost one-third (31%) reported an excellent HL level. About 41% of study participants were overweight and further 22% were obese. In multivariate analysis, there was evidence of a strong and significant association between BMI and HL: the odds of overweight/obesity were two times higher (OR = 2.0, 95% CI = 1.3-3.1) among inadequate HL individuals compared with excellent HL participants.Conclusion Our findings, pertinent to a transitional country in the South East Europe, point to a strong, consistent and highly significant association between BMI and HL, irrespective of a wide array of socio-demographic characteristics.
