OBJECTIVES: The eating habits of most Lithuanian people do not adhere to the recommendations for a healthy diet. If children and adolescents were provided with the relevant information, it would not only improve their nutritional knowledge, but also their eating habits in adulthood and the subsequent health of their children. The objective of this study was to determine the need for information on nutrition among Lithuanian adolescents, the current knowledge of adults regarding recommendations for the consumption of various food groups, and the factors that influence both the need for information and the current knowledge. METHODS: Two cross-sectional studies were conducted, consisting of 3,574 adolescents aged 14-18 years and 1,007 adults aged 18-75 years. Logistic regression models with confidence intervals of 95% were used to determine the influence of various socio-demographic factors on the adolescent need for information on nutrition and the adult knowledge of nutrition. RESULTS: A total of 66.7% of adolescents stated that they need information regarding nutrition, whereas 29.8% indicated that they lack such information. Significantly more girls than boys, and more students from schools in urban areas than students from schools in rural areas, expressed their need for information on nutrition. Lithuanian adults lacked knowledge of recommendations for the consumption of various food groups. Women and respondents with higher education degrees were found to have more knowledge on recommendations of the consumption of various food groups compared to men and respondents of other levels of education respectively. CONCLUSIONS: The results of this study demonstrate that the required information on nutrition must be continuously provided via various channels to both adolescents and adults, and socio-demographic factors must be taken into account when planning public health intervention measures.
