Age-Related Differences in Dietary Intake and Nutritional Status Among Older Adults in Croatia: Results from a...

Understanding nutrient intake and diet quality in older adults is essential for promoting healthy ageing and quality of life. The aim of the study was to assess dietary intake and nutritional status in two age groups of older adults in Croatia (65-74 years and ≥75 years).

A total of 786 participants aged 65 and older were included in this cross-sectional study. Data from the National food consumption survey (OC/EFSA/DATA/2017/01), based on the EU Menu methodology, were used. Data collection included a general questionnaire, the International Physical Activity Questionnaire, two 24-h recalls or food diaries, and anthropometric measurements. The effects of body mass index and physical activity level on dietary intake were analysed using a general linear model.

21.5% of older adults in Croatia had a normal weight, while 78.5% of were classified as overweight or obese. Significant differences were recorded in energy and macronutrient intake between the two age groups. Body mass index was significantly associated with energy (kcal/day), fat intake (g/day), and intake of the meat, poultry, fish and eggs food group in the 65-74 year age group. In the ≥75 year age group, physical activity level showed an effect on energy, carbohydrates, and milk and dairy product intake. Intake of nutrient-dense foods and fluids was below recommendations in both observed groups.

The study results, based on a representative sample, provide the first overview of the nutritional status of older adults in Croatia. These findings offer a foundation for public health initiatives and further research on the nutritional status of the older population in Croatia.
